What is the solution to the following equation? -32-8x=-7x+8(8x-4)

Answers

the answer to your question is x=0

X=0

−32−8x=−7x+8(8x−4)

−8x−32=−7x+8(8x−4)

−8x−32=−7x+64x−32

−8x−32=57−32

−8−32+32=57−32+32

−8=57

How do you find the answer to 6*3pi but in pi form?

Answers


Well, look at it this way:

-- 6 x 3 cows = 18 cows.

-- 6 x 3 bottles= 18 bottles

-- 6 x 3 cellphones = 18 cellphones

-- 6 x 3 rocks= 18 rocks

-- 6 x $3 = $18

so

6 x 3π = 18π
6*3*3.14 thats the pi

The height of the pyramid in the diagram is three times the radius of the cone. The base area of the pyramid is the same as the base area of the cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?

Answers

B(cone)=B(pyramid)=r²π
V(pyramid)=1/3 * B * H = 1/3 * r² π * 3 r ( 3 will cancel out )= r³ π
Answer: r³ π
Hello,

base of the pyramid :πr²
height=r

Volume=b*h/3=1/3* π*r^3

84c −4 = 72c−244 What is C?

Answers

Answer:

 c=20

Step-by-step explanation:

84c −4 = 72c−244

subract 72x from both sides

12c-4=-244

add 4 to both sides

12c=240

divide both sides by 12

c=20

The braking distance, D, of a car is directly proportional to the square of its speed, v. When d=5, v=10Find d when v=70​

Answers

d \propto v^2

$\implies d=kv^2$

substitute the given values, $5=k(10)^2\implies k=\frac1{20}$

now, $d=\frac{1}{20}\times( 70)^2=\frac{70\times70}{20}=245$
