Louis owns a rectangular piece of property with an area of 1, square miles. The length of the property is 2) miles.
What is the width of the property?
mile
O2 miles
O 3 miles
O4 miles
Answer:
The Width of the property is 1/2 (or 0.5) miles
Step-by-step explanation:
Step I - Formula for the length of a rectangle is given as
L = [tex]\frac{A}{w}[/tex]
Where L = Lenght
A = Area and
w = Width
Step II - Insert values
We have L to be equal to 2 Miles, and
W to be equal to 1 square mile
Therefore
2 = [tex]\frac{1}{w}[/tex]
To obtain w, we have to collect like terms to one side of the equation by cross multiplying
So
[tex]\frac{2}{1}[/tex] = [tex]\frac{1}{w}[/tex]
Cross multiplying we have
2w = 1
to get the value of w, we divide both sides by 2
[tex]\frac{2w}{2}[/tex] = [tex]\frac{1}{2}[/tex]
On the left side we are left with w, whilst on the right side we are left with a fraction - 1/2 (which in decimal form is 0.5)
Therefore, w = 0.5 Miles and this is the width of the property.
To confirm, Area of a rectangle is given by A = w * l
If we insert our figures, we'd get 0.5 x 2
Which is equals to 1 which was given in the question.
Cheers!
What percentage of the data values falls between the values of 27 and 45 in the data set shown?
25
30
35
40
45
50
25%
50%
75%
O 100%
Answer:
50%
Step-by-step explanation:
So the values that fall between 27 and 45 are 30, 35, 40. So that's 3 values out of 6, and 3/6 = 1/5 = 50/100. So the answer is 50%

On a separate sheet of paper: Respond to the following question. Show work, explain, be neat
Ann and Sue are saving money. Ann begins with $20 and saves $5 per week. Sue begins with no money, but can save
$10 per week.
1. Write a System of Equations representing Ann and Sue's savings.
Let x= # of weeks; y= Total amount of money saved
2. How many weeks will it take for the two girls to have the same amount of money?
How much money will they have at that time?
*Solve using TWO of the three methods you have learned (Table, Graph, Equal Values).
*Solution must be SHOWN and STATED in each representation.
Answer:
In 4 four weeks, they'll have the same amount of money
Step-by-step explanation:
1. Ann: y=5x+20; Sue: y=10x
2. You have to set both equations equal to each other so, 5x+20=10x. Solve for x. Take 5x away from each side, 20=5x. Divide both sides by 5, 4=x.
With the equations, you can graph and where the two lines meet is where they'll have the same amount of money.

Answer:
The radius of mercury is 6 times larger than the radius of hydrogen and the radius of uranium is 7 times larger than the radius of hydrogen.
Step-by-step explanation:
For mercury,
[tex]Ratio=\frac{radius of Hg}{radius of H} \\=\frac{1.5e-10}{2.5e-11} \\=6[/tex]
For uranium,
[tex]Ratio=\frac{radius of U}{radius of H} \\=\frac{1.75e-10}{2.5e-11} \\=7[/tex]
A gardening store wants to but supplies that cost $1,500. They can afford 4/5 of the total cost. How much can he store afford?
Answer: They can afford $1200 .
Step-by-step explanation:
Given : The total cost = $ 1500
Gardening store can afford [tex]\dfrac45[/tex] of the total cost.
Then, the amount they can afford can be computed as:
[tex]\dfrac45\times \text{(Total cost)}\\\\=\dfrac45\times(1500)\\\\=4\times300\\\\=1200[/tex]
i.e. The amount the store can afford = $ 1200
Therefore, they can afford $1200 .

Solve for x
Answer:
x = 10.5
Step-by-step explanation:
Firstly, in geometry, you may have to prove that the two triangles pictured are similar.
Since the two horizontal lines are marked, they are assumed to be parallel.
Therefore, if the lines are parallel, the two bottom angles of each triangle can be treated as the same due to the [Corresponding Angles Theorem], respectively
As such, the two triangles can be seen as SIMILAR as proven by Angle-Angle Similarity.
Now that we've proven both triangles to be similar, we can then set up ratios for the sides:
[tex]\frac{8}{6}[/tex] = [tex]\frac{8+14}{y}[/tex]
Note: we are using y as a measure of the entire right side of the triangle, so
y = 6 + x
Continuing on, if you cross-multiply the fractions to solve for y:
8y = 6 * 22
Simplify.
8y = 132
Simplify again.
y = 16.5
We are not done yet! We are solving for x, so remember y = 6 + x
16.5 = 6 + x
Solve for x.
x = 10.5
A sine function has a maximum y value of 8 and a minimum y value of -2. The period of the sine function is 4pi, and there is no phase shift/horizontal translation. What is the equation of the sine function?
Answer:
[tex]\displaystyle y = 5\sin(\frac{1}{2} x) +3[/tex]
Step-by-step explanation:
The Sine Function
The general form of the sine function (with no phase shift) is:
[tex]y = A\sin(\omega x) +M[/tex]
Where:
A = Amplitude
ω = angular frequency
M= Midline or vertical shift
The midline can be calculated as the mean value of the maximum and minimum values of the oscillation, thus:
[tex]M=\frac{8-2}{2}=3[/tex]
The amplitude is half the difference between the maximum and minimum values of the oscillation:
[tex]A=\frac{8+2}{2}=5[/tex]
The angular frequency is calculated in terms of the period T as:
[tex]\displaystyle \omega=\frac{2\pi}{T}[/tex]
Since T=4π:
[tex]\displaystyle \omega=\frac{2\pi}{4 \pi}=\frac{1}{2}[/tex]
Substituting in the general form of the sine function:
[tex]\boxed{\displaystyle y = 5\sin(\frac{1}{2} x) +3}[/tex]
The first choice is correct

If x varies inversely with ³√y, and x=3 when y=64 find x when y=1000
Answer:
Statement says that x varies inversely with ³√y
According to the above problem, we get
x=k/³√y, where k is a constant
Now, by putting x=3 when y=64
we have to find the value of k
3=k/³√64
3=k/4
k=3×4
k=12
Now, by putting the value of k
we have a find the value of x when y=1000
x=12/³√1000
x=12/10
x=1.2
★ x=1.2 is the right answer.

2. The area of a trapezium is 1080
cm2. If the lengths of the parallel
sides are 55.6 cm and 34.4 cm,
then find the distance between
them.
Answer:
Therefore, the distance (height) is 24cm.
Brainliest plzzzzz
Step-by-step explanation:
Area of trapezium = 1/2 × (a+b) × h
*a and b are the parallel lengths
Now we are going to find the distance, which is height (also known as 'h').
First, substitute the given values into the equation.
1080 = 1/2 × (55.6 + 34.4) × h
Move the 1/2 over to 1080 and divide.
1080 ÷ 1/2 = (55.6 + 34.4) × h
2160 = (55.6 + 34.4) × h
Add the numbers in the brackets.
2160 = 90 × h
Move 90 over to 2160 and divide.
2160 ÷ 90 = h
24 = h
Step-by-step explanation:
area = a+b/2×h
1080=55.6+34.4/2×h
1080×2=55.6+34.4h
2160=90h
h=2160/90
h=24
