The local public pool is a rectangle with two semicircles.

Reptile [31]

The area of the surface of the pool is 7322.64 m².

<h3>What is Area of rectangle?</h3>

The area of rectangle is product of length and its breadth.

i.e., length * breadth

Given: Length = 100 m, Width = 52 m and Diameter = 52 m

Area of rectangle,

= 100 × 52

= 5200 m²

Now,

Area of semicircle = 1/2 × πr²

=1/2 × 3.14 × 26²

= 1061.32 m²

Hence, area of the surface of the pool is

= 1061.32 + 1061.32 + 5200

= 7322.64 m²

600 or 600 decreased by 20% and then increased by 20% of the result? Which amount is larger and by how much

ohaa [14]

Answer:

The initial value of 600 is larger and larger by 24.

Step-by-step explanation:

First of all a 20% decreased of 600.

So, the new value will be $600(1 - \frac{20}{100}) = 600 \times 0.8 = 480$ .

Now, then it is increased by 20% i.e. 480 will be increased by 20%.

So, the new value will be $480(1 + \frac{20}{100}) = 480 \times 1.2 = 576$ .

Therefore, the initial value of 600 is larger and larger by (600 - 576) = 24. (Answer)

Which equation represents a linear function? A) y = |x| B) y = x2 C) y = -3x3 D) y = 1 4 x

Step2247 [10]

Linear means the highest exponent on the placholder is 1
it is also just a straight line

y=|x| is like y=(√x)², it is 2 straight lines

B. y=x², exponent is 2 so no

C. y=-3x³, exponent is 3, so no

D. y=1/4x, yep

D is the answer
