Answer:

Step-by-step explanation:

Surface area of sphere = 4πr²

4πr² = 500

4*3.14*r² = 500

r² = $\frac{500}{3.14*4}\\$

r² = 500*100/3.14*4*100

r² = 500*100/314*4

r² = 39.80

r =√39.8

r= 6.30 meters

The average mass of an ant is approximately 3 × 10 − 3 grams. The average mass of a giraffe is approximately 2 × 10 3 kilograms.

Vika [28.1K]

Given that average mass of an ant $= 3 \times 10^{-3}$ grams.

Given that average mass of a giraffe $= 2 \times 10^{3}$ Kilograms.

Now we have to find about how many times more mass does a giraffe have than an ant. Before carring out any comparision, we must make both units equal.

Like convert kilogram into gram or gram into kilogram.

I'm going to convert kilogram into gram using formula

1 Kg = 1000 g

So the average mass of a giraffe $= 2 \times 10^{3} *10^3$ grams.

Now we just need to divide mass of giraffe by mass of ant to find the answer.

$\frac{2 \times 10^{3} *10^3 }{3 \times 10^{-3} }$

$= \frac{2 \times 10^{3} *10^3 *10^{3}}{3 }$

$= \frac{2 \times 10^{3+3+3}}{3 }$

$= \frac{2 \times 10^9}{3 }$

$= \frac{2}{3 } \times 10^9$

=666666666.667

Hence final answer is $\frac{2}{3 } \times 10^9$ which is approx 666666666.667.

Which is the better by three toy cars for 7.50 or seven Toycars for 16.45

Len [333]

Answer:If I’m correct I believe seven you cars for 16.45 would be better

Step-by-step explanation:

Since three cars cost 7.50 you would divide 7.50 to get the cost for each car which would give you 2.50 and since seven cars cost 16.45 you would divide 16.45 by 7 to get the cost of each car which would come out to 2.35 making it a better buy
