The length of the base of an isosceles triangle is x = 7
Yes, there is enough information to solve for x. The perimeter of an isosceles triangle is the sum of all its sides. Since the perimeter is given and two sides are known, it can be expressed as follows:
x + (3x +2) + (3x +2) = 39
Solving for x,
5x + 4 = 39
5x = 35
x = 7
Therefore, the length of the base is 7. This can be verified by substituting the value of x into the equation for the perimeter, which would yield a result of 39.

If (x,1), (-3,7), (-5,9), (5,4) find the value of x
The value is x=9, when the points are (x,1), (-3,7), (-5,9), (5,4).
The slope formula is defined as the formula used to calculate the steepness of a line and to determine how much it's inclined. To calculate the slope of the lines, we need the x and y coordinates of the points.
The formula to calculate slope is given as,
m = (y2 - y1)/(x2 - x1)
where m is the slope of the line,
x1, x2 are the coordinates of the x-axis,
y1 and y2 are the coordinates of the y-axis.
Consider the Points as A=(x,1),B=(-3,7),C=(-5,9),D=(5,4)
Now, take two points C, D to know the m value:
Slope = y₂ - y₁/ x₂-x₁
m1 = 4 - 9 / 5- [-5]
= -5 / 5+5 = -5/10 = -1/2
m1 = -1/2
Consider the next two points A, B:
A(x, 1), B(-3,7)
Slope of AB m2 = 7- 1 / -3 - x
m2= 6/-3-x
As AB || CD, m2 = m1

Find measures for 4-6
The measures of the angles of the triangles are
m∠1 = 55°
m∠2 = 125°
m∠3 = 35°
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the first triangle be represented as ΔABC
Let the second triangle be represented as ΔCDE
And ∠BAC = m∠1
And , ∠CDE = m∠3
Now , from the triangle ΔABC
∠ABC = 180° - 110° ( Angle of a straight line is 180° )
So , the measure of angle ∠ABC = 70°
The sides of the triangle AC and BC are similar
So , The angles of the triangle are = 70° + x + x = 180°
On simplifying the equation , we get
70° + m∠1 + m∠1 = 180°
Subtracting 70° on both sides of the equation , we get
2m∠1 = 110°
Divide by 2 on both sides of the equation , we get
m∠1 = 55° = ∠ACB
And , ∠ACB and m∠2 are on a straight line
So , m∠2 = 180° - 55°
On simplifying the equation , we get
m∠2 = 125°
The triangle ΔCDE is a right triangle with ∠DCE = m∠1 ( vertically opposite angles )
So , the angles of the triangle are = 90° + 55° + m∠3 = 180°
On simplifying the equation , we get
145° + m∠3 = 180°
Subtracting 145° on both sides of the equation , we get
m∠3 = 35°
Hence , the measures of the angles of the triangles are are m∠1 = 55° , m∠2 = 125° , m∠3 = 35°

The checkpoint Odalis will be when they catch up to Jaquan is 0.1 km.
Given that, Jaquan passed a checkpoint jogging at a constant speed of 9 km/hr.
2 minutes later Odalis passed the same checkpoint.
Odalis runs at a constant speed of 12 km/hr.
We know that, 1 hour = 60 minutes
So, 2 minutes = [tex]\frac{2}{60}[/tex] hour
= [tex]\frac{1}{30}[/tex] hour
So, the distance = [tex]9\times\frac{1}{30}[/tex]

When the speed is 12 km/hr, we get
Distance = [tex]12\times\frac{1}{30}[/tex]
= [tex]\frac{2}{5}[/tex] km
Now, [tex]\frac{2}{5} - \frac{3}{10}[/tex]

A 10 cm thick grindstone is initially 200 cm in diameter, and it is wearing away at a rate of. At what rate is it's diameter decreasing?.
The diameter is twice the radius, so it is decreasing at a rate of [tex]$2(1.26 \times 10^{-2} \ \text{cm}/\text{hr}) = \boxed{2.52 \times 10^{-2} \ \text{cm}/\text{hr}}$[/tex]
The volume of the grindstone is [tex]$\pi r^2 h = \pi \cdot 100^2 \cdot 10 = 3141600 \ \text{cm}^3$[/tex], so the rate at which it is wearing away is [tex]$\frac{50}{3141600} = 1.59 \times 10^{-4} \ \text{cm}^3/\text{hr}$[/tex]
The grindstone is a cylinder, so its volume is proportional to its radius squared. Therefore, the radius is decreasing at a rate proportional to [tex]$\sqrt{1.59 \times 10^{-4}} = 1.26 \times 10^{-2} \ \text{cm}/\text{hr}$[/tex].

The diameter of the grindstone is decreasing at a rate of 5/(πr) cm/hr.
Therefore the answer is b) 5/ (πr) cm/hr.
The grindstone is losing material at a rate of 50 cm³/hr, and since it is a cylinder, we can use the formula for the volume of a cylinder to find the rate at which its diameter is decreasing.
The volume of a cylinder is given by:
[tex]V= \frac{ \pi D^{2} h}{4}[/tex]
where V is the volume, d is the diameter and h is the height (in this case the thickness of the grindstone).
We know that the grindstone is losing material at a rate of 50 cm³/hr, and that the grindstone's thickness is 10 cm. To find the rate at which the diameter is decreasing, we need to find the rate at which the radius is decreasing, which we can find by differentiating the volume equation with respect to time.
So
[tex]\frac{dV}{dt} = -50\ cm^{3}/hr[/tex]
[tex]\frac{d(\frac{\pi\\D^{2}h }{4}) }{dt} = -50\ cm^{3}/hr[/tex]
[tex]\frac{2}{4}\pi Dh\frac{dD}{dt} = -50\ cm^{3}/hr[/tex]
Substitute the known values,
[tex]\frac{2}{4}\pi *(D)*(10cm)\frac{dD}{dt} = -50\ cm^{3}/hr[/tex]
[tex]\frac{dD}{dt}= (-50 cm^3/hr)*\frac{4}{2\pi *(D cm)*(10 cm)}[/tex]
[tex]\frac{dD}{dt}= \frac{-10}{\pi D}cm/hr[/tex]
We know D = 2r
[tex]\frac{dD}{dt}= \frac{-10}{\pi*(2r)}cm/hr[/tex]

I WILL GIVE 20p to anyone who answers correctly!!!
Answer: $180 for 4 shirts and 360 for 8 shirts (this includes the 10% discount for both answers)
Step-by-step explanation: First, we have to multiply 50 by 4, since each shirt is $50 and there are 4 shirts to purchase. The answer is $200, but you have a 10% discount to consider. 10% of 200 is 20, so subtract $20 from 200, and you get $180 for 4 shirts. To find out the amount of money it costs to pay for 8 shirts, you can simply add 180 and 180 together and it'll give you 360. This way, the 10% discount will not be left out.

O$1,409.15
O$4,145 24
O $5,000.00
Answer:
(a) $1049.15
Step-by-step explanation:
You want to know the interest earned by an account that pays 3.2% interest compounded semiannually if the balance is $6049.15 after 6 years.
Compound interestThe formula for the balance of an account earning compound interest is ...
A = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.
ApplicationWe have ...
6049.15 = P(1 +0.032/2)^(2·6) = P(1.016^12)
The amount of interest earned is the difference between the account balance and the principal:
interest = 6049.15 -(6049.15/1.016^12) ≈ 1049.15
The total amount of interest earned is $1049.15.

Ghart bought 18 boxes.Rico bought 36 boxes.Mia bought 45 boxes.We can decompose these numbers as a product between their prime factors, we will get:
18 = 2*3*3
36 = 2*2*3*3
45 = 5*3*3
You can see that the largest common factor is 3*3 = 9
So the maximum number of boxes that each pack can have is 9 boxes.
In that case:
Garth bought 18/9 = 2 packs.
Rico bougth 36/9 = 4 packs.
Mia bought 45/9 = 5 packs.

Behold. Longest explanation for 1 + 1 I have done.
First you take the first number that you have, which is 1(one). and then you take the second number that is shown, which is also 1(one). Then you check the symbol in which what the problem is asking you to do, which is +(plus). Then, finally you can see what the problem is asking. The equation translates to: 1 + 1 (one plus one.) Plus is the symbol in which what a problem is asking you to add add two or more numbers together, so you will add 1 and 1 together. To see how to do so is you can count to get the sum. We know that the number that comes first when counting is 1, so you can begin by counting up by 1's, until you get the sum. The number that comes after 1 is 2, which so happens to be 1 number after 1, so which is what the question is asking, so therefore, 1 + 1 is equal to 2. (The sum of 1 and 1 is 2.)
No haters better delete this. This took time!
Answer:1. Let a = 1 and b = 1 .
2. Now this means that a = b .
3. If we multiply both sides by a we get a^{2} = ab .
4. If we then subtract b^{2} from both sides we would have a^{2} - b^{2} = ab - b^{2} .
5. We can then factorise both sides to get (a + b)(a - b) = b(a - b) .
6. Dividing both sides by (a - b) would give us a + b = b .
7. Substituting back the values of a = 1 and b = 1 would give us that 1 + 1 = 1 .
8. So this "proves" that 1 + 1 = 1 not 2 .
Except that in step 6, when we are dividing by a - b , we are in fact dividing by zero. This is a violation of the rules of mathematics :/ soo... Um lol...

Use the following box plot on TV Time per night (in minutes) to answer the
following question:
0 15
60
110
225
Use the outlier rule to determine if the 225 minutes of TV watching time is
an outlier.
O Yes, because 225 minutes is greater than 205 minutes.
O No, because 225 is not greater than 252.5 minutes.
O Yes, because it is more than twice as much time as the 110 minutes.
O Yes, because it is more than 95 minutes away from the upper quartile.
Yes, because 225 minutes is greater than 205 minutes.
what is outlier rule?Outlier rules, also known as outlier detection algorithms, are algorithms designed to detect the presence of outliers in a dataset. Outliers are data points that are significantly different from the rest of the data, and can be caused by measurement error, experimental error, or some other anomaly. Outlier rules are used to identify and remove outliers from data sets in order to improve the accuracy of data analysis and modeling. Outlier rules typically use some combination of statistical measures, such as mean, median, and standard deviation, to detect the presence of outliers in the data.In this question answer is
Yes, because 225 minutes is greater than 205 minutes.
This can be determined by using the outlier rule
which states that any data point that is more than 1.5 times the interquartile range (IQR) away from the upper quartile (Q3) is considered an outlier.
The IQR is calculated as Q3 - Q1,
which in this case is
110 - 15 = 95. Therefore,
1.5 times the IQR is 95 x 1.5 = 142.5.
The upper quartile (Q3) is 110,
so any data point more than 205 (110 + 142.5) is considered an outlier, including 225.

Answer:
-3.5,-3,-2[tex]\frac{1}{2}[/tex], -2,2.5
Step-by-step explanation:
For numbers that are negative, the larger the number is the lesser the value is. For numbers that are positive, the larger the number is the larger is value is. Positive numbers are always greater than negative numbers.
Answer:
-3.5 | -3 | -2[tex]\frac{1}{2}[/tex] | -2 | 2.5 |
Step-by-step explanation:
Negative number are smaller than positive numbers so 2.5 is the largest number. Negative numbers are kind of opposite of positive numbers. The larger the negative number is, the smaller it is. With positive numbers, the larger the number, the larger the value is.
Fencing encloses a rectangular backyard that measures 200 feet by 600 feet. A blueprint of the backyard is drawn on the coordinate
plane so that the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0).
A circular flower garden is dug to be exactly in the a center of the backyard, with a radius of 40 feet. This garden is represented of on the
blueprint.
What is the equation of the flower garden represented on the blueprint?
Enter your answer by filling in the boxes.
The equation of the circular flower garden represented on the blueprint is (x-5)²+(y-15)² = 4
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Fencing encloses a rectangular backyard that measures 200 feet by 600 feet. A blueprint of the backyard is drawn on the coordinate
plane so that the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0).
A circular flower garden is dug to be exactly in the centre of the backyard, with a radius of 40 feet. This garden is represented of on the blueprint.
Since, the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0) therefore, it will form a rectangle with width 10 units and height 30 units.
In this situation, the centre of the rectangle is at (5, 15) (Half of the width in the first coordinate and half of the height in the second one)
Since, we know that the equation of the circle is given by;
(x-a)²+(y-b)² = R²
Where, (a, b) is the centre point and R is the radius,
Therefore, the equation of the flower garden will be;
(x-5)²+(y-15)² = R²
Now, solving for R,
We know that the rectangular backyard width is 200 feet and this is represented with a rectangle in the blueprint with width 10 units
10 units = 200 ft
Therefore, 40 ft = 2 units
Therefore, The radius of 40 feet is represented with 2 units in the blueprint.
Now we replace R = 2 in the equation :
(x-5)²+(y-15)² = 2²
(x-5)²+(y-15)² = 4
Hence, the required equation is (x-5)²+(y-15)² = 4
