Answer:

It would be D). 2.0 because we know the square root of 2 over the square root of 5 is the square root of 10 over 5. Now, we can plug in pi, giving us the square root of 10 times pi over 5. Giving us 1.98 which can be rounded up to 2.0

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression (√2)π/(√5) is 2.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of the expression (√2)π/(√5) can be written as,

\dfrac{\sqrt2 \pi}{\sqrt5}\\\\= \sqrt{\dfrac25}\pi\\\\=\sqrt{0.4} \times \pi\\\\

= 0.6324 × π

= 1.9869 ≈ 2

Hence, The value of the expression (√2)π/(√5) is 2.

The expression that represents the volume of the composite figure is \pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12). The correct option is the third option \pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)

<h3>Calculating Volume </h3>

From the question, we are to determine the expression that represents the volume of the composite figure

The composite figure consist of a cylinder and a cone

∴ Volume of the composite figure = Volume of the cylinder + Volume of the cone

Volume of a cylinder = \pi r^{2} h

Where r is the radius

and h is the height of the cylinder

Volume of a cone = \frac{1}{3} \pi r^{2} h

Where r is the radius

and h is the height of the cone

Consider the composite figure

For the cylinder part

r = 5

h = 13

For the cone part

r = 5

h = 25 - 13 = 12

Thus,

Volume of the composite figure = \pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)

Hence, the expression that represents the volume of the composite figure is \pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12). The correct option is the third option \pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)

X= Kaden
Quan= 15

4/5 (3x-10) = 15
12/5x-8 = 15
12x- 40= 75
12x= 40+ 75
12x = 115
x= 115/12
x= 9.583
