$12(1)/(2)$ percent of 96 men is 12 men.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, $12(1)/(2)$ % of 96 men.

Simplify the following expression.(45x + 64y) - (3x - 16y)
A.42x - 80y
B.42x - 48y
C.42x + 80y
D.42x + 48y

Answers

(45x + 64y) - (3x - 16y)

First, simplify to remove brackets. / Your problem should look like: $45x + 64y - 3x + 16y$
Second, gather like terms. / Your problem should look like: $(45x - 3x) + (64y + 16y)$
Third, simplify. / Your problem should look like: $42x + 80y$

Answer: C) 42x + 80y

$(45x + 64y) - (3x - 16y)$
$45x + 64y -3x +16y$
$42x+64y+16y$
$42x+80y$
The answer is: $C. 42x+80y$

Find the surface area of a bar of soap if the diameter is 5 cm and the height is 2cm .

Answers

Please see the pic, I'd solved in it.

Given that:
Diameter = 5 cm
which means,
Radius= $(diameter)/(2)$ = $(5)/(2)$ = 2.5 cm (radius is half the diameter)
and Height = 2 cm
We can assume that the shape is cylindrical

Formula of the Surface Area of a Cylinder
=2 $\pi$ r² + 2 $\pi$ rh
=2 $\pi$ (2.5)² + 2 $\pi$ (2.5)(2)
=12.5 $\pi$ + 10 $\pi$
=22.5 $\pi$ cm² (in terms of $\pi$ )
=70.69 cm² ≈ 70.7 cm²
