3 0

Answer:

25m/s

Step-by-step explanation:

distance = 30km = 30× 1000m

time = 20 min = 20 × 60 = 1200sec

we know,

speed = distance/time taken

= 30000/1200

= 25m/s

\bf \cfrac{24w^{10}+8w^{12}}{4w^4}\impliedby \textit{distibuting the denominator}
\\\\\\
\cfrac{24w^{10}}{4w^4}+\cfrac{8w^{12}}{4w^4}\implies 6w^{10}w^{-4}+2w^{12}w^{-4}\implies 6w^{10-4}+2w^{12-4}

Susan designed a circular pool with a diameter of 25 meters. What is the area of the bottom of the pool? Round to the nearest te
ludmilkaskok [199]
Given:
circular pool with a diameter of 25 meters.

find: area of the bottom of the pool.

It is safe to assume that the diameter of the pool is the same from the top of the pool to the bottom of the pool.

Area of a circle = π r²
where: 
π = 3.14
r = diameter / 2 = 25 meters / 2= 12.5 meters

Area of a circle = 3.14 * (12.5m)²
                        = 3.14 * 156.25 m²
Area of a circle = 490.625 m²

490.625 m² round to the nearest tenth is 490.60 m²

We round down because the number after 6 is 2. Whenever a number to be rounded off is followed by 0,1,2,3,and 4. Then, the number is rounded down.
