E/4 + 2d - 3 when e = 12 and f = 1/2.
Oxana [17]

Given that,

An expression : \dfrac{e}{4}+2f-3

To find,

The value of the above expression when e = 12 and f = 1/2

Solution,

We have,

\dfrac{e}{4}+2f-3

Put e = 12 and f = 1/2

So,

=\dfrac{12}{4}+2\times \dfrac{1}{2}-3\\\\=3+1-3\\\\=1

So, the value of the above expression is 1.

Cylinder A has a radius of 7 inches and a height of 5 inches. Cylinder B has a volume of 490π. What is the percentage change in
olasank [31]

Percentage change is 100% increase.

Step-by-step explanation:

  • Step 1: Find volume of cylinder A using equation, V(A) = πr²h, where r = 7 in and h = 5 in

⇒ V(A) = π × 7 × 7 × 5 = 245π

and V(B) = 490π

  • Step 2: Calculate percentage change from V(A) to V(B)

⇒ % change = [V(B) - V(A)/V(A)] × 100 = (490π - 245π/245π) × 100

                     = 245π/245π × 100 = 100% increase
