The perimeter of a scene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used to find the side lengths if the longest side measures 6.2cm?
Answer:
[tex]\huge\boxed{6.2 + (\frac{6.2}{2}) + x = 14.5}[/tex]
Step-by-step explanation:
To create an equation for this, we have to note a couple of things.
A scalene triangle has 3 different length sidesAll sides will add up to the perimeter (in this case 14.5)We know that the longest side is 6.2 cm long. We also know that the longest side is twice the length of the shortest side. Therefore, the shortest side will be half the amount of the longest side.
Basically - we divide the longest side by 2 (6.2) so [tex]\frac{6.2}{2}[/tex].
We don't know the third side. However, we know the total perimeter (14.5). Therefore, we can use a placeholder for the third side - [tex]x[/tex].
Adding up all the sides, we have [tex]6.2 + (\frac{6.2}{2}) + x = 14.5[/tex].

A. 2x^3 + 3/2x+1
B. 2x^2 + 3/2x-5
C. x^2-6
D. 2x^2 + x/2+1
Answer:
B
Step-by-step explanation:
We have the two functions:
[tex]f(x)=\frac{x}{2}-2\text{ and } g(x)=2x^2+x-3[/tex]
And we want to find:
[tex](f+g)(x)[/tex]

Suppose the manager of a gas station monitors how many bags of ice he sells daily along with recording the highest temperature each day during the summer. The data are plotted with temperature, in degrees Fahrenheit (°F), as the explanatory variable and the number of ice bags sold that day as the response variable. The least squares regression (LSR) line for the data is Yˆ = −114.05+2.17X. On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.
1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.
2. Compute the residual at this temperature.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Equation of regression line :
Yˆ = −114.05+2.17X
X = Temperature in degrees Fahrenheit (°F)
Y = Number of bags of ice sold
On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.
X = 82°F ; Y = 66 bags of ice sold
1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.
X = 82°F
Yˆ = −114.05+2.17(82)
Y = - 114.05 + 177.94
Y = 63.89
Y = 64 bags
2. Compute the residual at this temperature.
Residual = Actual value - predicted value
Residual = 66 - 64 = 2 bags of ice

Step-by-step explanation:
Here we have the equation y= -3/2x - 3.
In order to graph this, we will put replace the x with a number and the solution will be y. For example, x is 2. That would make y, -6. Then we put those together (2,-6) and we graph that and so on.
find y if x is equal to 20
Answer:
Hope this help
Step-by-step explanation:
Plug in the y value found from the first equation in to the second equation in order to find the x value. In the previous example, this means the second equation becomes "x + 5(2- 3x) = 20"
Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7.
Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

A parent places in the saving bank Rs 500 on his child's first birthday, Rs 1000 on his second, Rs 1500 on his third and so on increasing the amount by Rs 500 on each birthday. How much will he save up when the child reaches the sixteenth birthday, the latter inclusive?
Answer:
The child will reach Rs 68,000 on his 16th birthday
Step-by-step explanation:
The parent increases the amount by Rs 500 each birthday which means
1st: 500
2nd: 1,000
3rd: 1,500
4th: 2,000
5th: 2,500
6th: 3,000

12th: 6,000
13th: 6,500
14th: 7,000
15th: 7,500
16th: 8,000
and then you add all of those numbers together and it equals 68,000
Step-by-step explanation:
The formula to calculate 16th term of an arithematic progression is tn=a+(n-1). By using given formulae we can find out the money that the child's parent saved till his 16th birthday. After that the formula to calculate the sum to n terms of an AP id Sn= n/2[2a+(n-1)d]. By using the formula we can find out the sum.

Bob has a recipe for salad dressing the recipe says to mix 1/4 cup lemon juice. 1/8 cup mustard and 1/4 cup vinegar how much lemon juice does he need to make 4 cups of salad dressing show your work
Answer:
Step-by-step explanation:
1/4*x + 1/8*x + 1/4 * x = 4 cups
5/8 * x = 4 cups Multiply both sides by 8/5
5/8 * 8/5 x = 4 8/5
x = 32/5
x = 6.4
That means that each ingredient must be multiplied by 6.4
1/4 * 6.4 = 1.6 cups lemon juice
1/8 * 6.4 = .8 cups mustard
1/4 * 6.4 = 1.6 cups vinegar
Total = 4 cups.
(5x + 4)° (8x – 710°
Answer:
x = 19
Step-by-step explanation:
Assuming the question was (5x + 4)° (8x – 71)°=180° not (5x + 4)° (8x – 710°,
Simplifying
(5x + 4) + (8x + -71) = 180
Reorder the terms:
(4 + 5x) + (8x + -71) = 180
Remove parenthesis around (4 + 5x)
4 + 5x + (8x + -71) = 180
Reorder the terms:
4 + 5x + (-71 + 8x) = 180
Remove parenthesis around (-71 + 8x)
4 + 5x + -71 + 8x = 180
Reorder the terms:
4 + -71 + 5x + 8x = 180
Combine like terms: 4 + -71 = -67
-67 + 5x + 8x = 180
Combine like terms: 5x + 8x = 13x
-67 + 13x = 180
Solving
-67 + 13x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '67' to each side of the equation.
-67 + 67 + 13x = 180 + 67
Combine like terms: -67 + 67 = 0
0 + 13x = 180 + 67
13x = 180 + 67
Combine like terms: 180 + 67 = 247
13x = 247
Divide each side by '13'.
x = 19
Simplifying
x = 19

Answer:
In general, an unresolved nth root, commonly involving a radical symbol ^n√x, is known as a surd. However, the term surd or "surd expression" (e.g., Hardy 1967, p. 25) can also be used to mean a sum of one or more irrational roots. In the mathematical literature, the term arises most commonly in the context of quadratic surds.

Step-by-step explanation:
We know that the sum of the angles of a triangle is 180
HCA + CAH + AHB = 180
80+ CAH + 90 = 180
Combine like terms
170 + HAC = 180
HAC= 180-170
HAC = 10
We also know that HCA + ACB is a straight line so it adds to 180
HCA + ACB = 180
80+ACB = 180
ACB = 180-80
ACB = 100
Since ACB is isosceles the base angles have the same measure so CAB = ABC
We know that the sum of the angles of a triangle is 180
CAB + ABC + ACB = 180
Replacing ABC with CAB
CAB + CAB + 100 = 180
2CAB + 100 =180
2 CAB = 180-100
2 CAB = 80
Divide by 2
CAB = 80/2
CAB = 40
Now find HAB
HAB = HAC + CAB
= 10 + 40
= 50
