Allie : (6.5 + 9) / 2 = 15.5/2 = 7.75 (mean of allie)
franco : (6 + 10.5)/2 = 16.5/2 = 8.25 (mean for franco)
blake : (8 + 7)/2 = 15/2 = 7.5 (mean for blake)

to find the mean, u would add up the number of hrs on those 2 days, then divide by 2.

Blake's mean would be : (4b + 4c) / 2 = 4d

How is the process of finding the surface area of a rectangular prism the same as finding the surface area of a triangular prism
harina [27]

Answer:

see the explanation

Step-by-step explanation:

we know that

The surface area of a prism is given by the formula

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

For both prism the formula is the same

How is it different?

Rectangular prism

The area of the base is given by the formula

A=LW -----> is the area of rectangle

where

L is the length and W is the width of rectangle

The perimeter of the base is given by

P=2(L+W) ---> is the perimeter of rectangle

The height H is the same in both cases

Triangular prism

The area of the base is given by the formula

A=\frac{1}{2} (b)(h) -----> is the area of the triangular base

where

b is the base of triangle and h is the height of triangle

The perimeter of the base is given by

P=(a+b+c) ---> is the perimeter of triangle

where

a, b and c are the length sides of triangle

The height H is the same in both cases

Parallelogram FGHI on the coordinate plane below represents the drawing of a horse trail through a local park.
Setler [38]
The answer is <span>A)(13, 8).

Distance I to F is:     yf - yi = -1 - (-4) = -1 + 4 = 3
Distance D to A is:   ya - yd = 8 - 2 = 6

</span>Distance D to A : Distance I to F = 6 : 3<span>
6 : 3 = 2, so scale factor is 2.

Among all choices, we see that the y point of another corner is 8, so we need to find x point.

Distance I to H is:                 xh - xi = -2 - (-7) = -2 + 7 = 5
Distance A to x corner is:    x - xa = x - 3

Since </span>Distance I to H is 5, and scale factor is 2, we have:
Distance A to x corner : Distance I to H = 2
Distance A to x corner = 2 * Distance I to H = 2 * 5 = 10

Distance A to x corner is:    xa - x = x - 3 = 10
x - 3 = 10
x = 10 + 3
x = 13
