Answer:

V_a=125 cubic\ inches

Step-by-step explanation:

From the question we are told that:

Height of pyramid A h_a=6

Height of pyramid B h_b=6

The volume of pyramid B  V_b= 312.5 cubic inches.

 

Generally the equation for volume for pyramid A is mathematically given by

Since they are similar

 \frac{l_a}{l_b}=\frac{V_a}{V_b}\\\\\frac{6}{15}=\frac{V_a}{312.5}\\\\V_a=\frac{6}{15}*312.5

 V_a=125 cubic\ inches

a building with a height of 32m casts a shadow that is 20m long. a person standing casts a shadow that is 1.2 m long how tall is
wlad13 [49]
Most of the information's required for solving the question is already given in the question.
Height of the building that casts a shadow of 20 m = 32 m
Then
Height of the man that casts a shadow of 1.2 m = (32/20) * 1.2 meter
                                                                             = 3.2 * 1.2 meter
                                                                             = 3.84 meter
So the actual height of the person casting a shadow of 1.2 meter is 3.84 meters. I hope that the procedure used for solving the problem is easy enough for you to understand. You can definitely use this method in future for solving problems of similar type without requiring any additional help from outside.

What is k/5.2 + 81.9= 47.2
weqwewe [10]
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)

k/5.2+81.9 = 47.2 // - 47.2

k/5.2-47.2+81.9 = 0

0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2

0.19230769*k = -(81.9-47.2) // : 0.19230769

k = (-(81.9-47.2))/0.19230769

k = 5.20000006*(47.2-81.9)

k = 5.20000006*(47.2-81.9)

Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>brainly.com/question/253764

Which is a simplified form of the expression -4(3r – 2) – 2(r + 1)?
Delicious77 [7]

Answer:

2 (3 - 7 r)

Step-by-step explanation:

Simplify the following:

-4 (3 r - 2) - 2 (r + 1)

-4 (3 r - 2) = 8 - 12 r:

8 - 12 r - 2 (r + 1)

-2 (r + 1) = -2 r - 2:

-12 r + -2 r - 2 + 8

Grouping like terms, -2 r - 12 r - 2 + 8 = (8 - 2) + (-12 r - 2 r):

(8 - 2) + (-12 r - 2 r)

-12 r - 2 r = -14 r:

-14 r + (8 - 2)

8 - 2 = 6:

6 - 14 r

Factor 2 out of 6 - 14 r:

Answer: 2 (3 - 7 r)
