V = (1/3)*B*H
3V = B*H ... multiply both sides by 3
B*H = 3V
B = (3V)/H ... divide both sides by H

Answer: Choice A

Answer:

Option A.

Step-by-step explanation:

The given formula for the volume of a pyramid is

$V=\dfrac{1}{3}Bh$

We need to find the equation which is equivalent to the given formula.

Multiply both sides by 3.

$V\times 3=\dfrac{1}{3}Bh\times 3$

$3V=Bh$

Divide both sides by h.

$\dfrac{3V}{h}=\dfrac{Bh}{h}$

$\dfrac{3V}{h}=B$

Hence, the correct option is A.

Answer:

30 waiters

Step-by-step explanation:

the ratio of 5 waiters to 2 cooks

you are given the total number of waiters and cooks = 42

write equation

x (5 + 2) = 42

7x = 42

x = 6

now distribute the x into waiters which is 5x or 5(6) = 30 waiters

additionally 2x is for cooks or 2(6) = 12 cooks; which adds up to 42

since they are all in the same line you only need to use 2 of the points I'm using (1,-1) and (2,1) next you do (x1,y1) and (x2, y2) which would be (1,2) and (-1, 1) then do y2-y1 / x2-x1 which would be 1/2

Factorise the following, using the identity a2 – 2ab + b2 = (a – b)2

Rasek [7]

The factorisation of the given expressions is as follows;

a) p²y²– 2py + 1 = (py -1)²
b) a²y² -2aby +b² = (ay - b)²

<h3>Factorization using identities</h3>

The given identity is;

a²– 2ab + b² = (a – b)²

From the given identity, we can conclude that;

In the expression (a);

py represents a in the identity and 1 represents b in the identity.

In the expression (b);

ay represents a in the identity and b represents b in the identity.

Hence, the factorised expressions are as represented above.
