This is just algebraic manipulation. The question asks you to isolate the equation for L.

Step 1) Multiply both sides by (R1+R2)

Step 2) Divide both sides by h

Doing those two steps will leave you with:

d(R1+R2)/h = L

So the answer is B.

Tahmar knows the formula for simple interest is I = Prt, where I represents the simple interest on an amount of money, P, for t
frez [133]
The formula to find the simple interest earned is
I = Prt
Solve for p by dividing both sides by rt to get
P=I/rt
P=?
I=20
R=0.05
T=5years
So
P=20÷(0.05×5)
P=80

Hope it helps!

What is the volume of the right rectangular prism? Enter your answer in the box.​
Nutka1998 [239]

Answer:

1000 cm²

Step-by-step explanation:

Given:

  • Length = 10 cm
  • Width = 12.5 cm
  • Height = 8 cm

<u>Formula:</u>

\text{Volume = Length} \times \text{Width} \times \text{Height}

Substitute the length, width, and the height of the prism to determine the volume of the prism.

\implies \text{Volume = 10} \times 12.5 \times 8

Simplify the right hand side of the equation, as needed;

\implies \text{Volume = 10} \times 12.5 \times 8

\implies \text{Volume =}\ 125 \times 8

\implies \boxed{\text{Volume =}\ 1000 \ \text{cm}^{2} }

Therefore, the volume of the prism is 1000 cm².
