We have to choose which expression represents the height of the prism.
The base is a square of edge length x units.
Base Area = x · x = x²
Volume of the prism = B · h
x³ = x² · h
h = x³ : x²
h = x
Answer: x units.

A boy leaves on a bicycle trip at the rate of 8 mph. One hour later the father, realizing that his son forgot his camping
KatRina [158]

Answer:

40 mph

Step-by-step explanation:

One hour includes 60 minutes

8/60=0.13(3 repeating)

You only need 15 minutes of time

0.13(3 repeating)*15=2

8+2=10 miles

15 minutes is 1/4 of an hour

10*4=40 mph

Find the center of the circle that you can circumscribe about DABC.
Vlada [557]

The center of the circle that circumscribe about DABC is (h,k) = (1, 5).

A circle can be modelled after a expression of the form:

A\cdot x + B\cdot y + C =-x^{2}-y^{2} (1)

We can determine all coefficients by knowing three <em>distinct</em> points on plane.

If we know that (x_{1}, y_{1}) = (2, 8), (x_{2}, y_{2}) = (0, 8) and (x_{3}, y_{3}) = (2, 2), then the solution of the system of linear equations is:

2\cdot A + 8\cdot B + C = -68 (2)

8\cdot B + C = -64 (3)

2\cdot A + 2\cdot B + C = -8 (4)

A = -2, B = -10, C = 16

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

x^{2}+y^{2}-2\cdot x -10\cdot y +16 = 0

(x^{2}-2\cdot x +1)-1+(y^{2}-10\cdot y +25)-25 +16 = 0

(x-1)^{2}+(y-5)^{2}= 10

The center of the circle that circumscribe about DABC is (h,k) = (1, 5).

The ratio of the sales of black coffee to sugar coffee to milk coffee is 3:7:5. The total sales of the three coffees is 300 cups
Virty [35]
Answer = $55
Because 3 + 7 + 5 = 15
The 3 = black coffee
The 7 = sugar coffee
And the 5 = milk coffee
So then u do 5/15 simplified = 1/3
So then do 1 /3 of $165 = $55

The test scores of a geometry class are given below.
Artyom0805 [142]
Variance is given by s^2 = [summation (x - mean)^2] / n.
mean = (90 + 75 + 72 + 88 + 85) / 5 = 82
Variance = [(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)] / 5
= [8^2 + (-7)^2 + (-10)^2 + 6^2 + 3^2] / 5
= (64 + 49 + 100 + 36 + 9] / 5
= 258 / 5
Therefore, the value of the numerator of the calculation of the variance of the data set is 258.
