The radii of Earth and Pluto are 6,371 kilometers and 1,161 kilometers, respectively. Approximately how many spheres the size of Pluto does it take to have the same volume as Earth?

Answers

Answer 1

Answer: so find the volume of them
volume of sphere=4/3pi times r^3
volume of earuth
4/3 times pi times 6371^3=aprox 1.08 times 10^12 (really big number so scientific notation)

volume of pluto
4/3 times pi times 1161^3=6.56 times 10^9

so pluto times x=earht
divide both sdies by pluto
x=earth/pluto
solve for x
earth=1.08 times 10^12
pluto=6.56 times 10^9
(1.08 times 10^12)/(6.56 times 10^9)=(1.08/6.56) times (10^12)/(10^9)
when dividing exponents, just subtract
12-9=3
so
1.08/6.56 times 10^3
0.164634 times 10^3
164.634
aprox 165 plutos will fit in earth

The junior class has 50 students. Twenty-five students take only French, 15 take only Latin, and 10 take both. If a student is chosen at random from the class, what is the probability that the student chosen takes either French only or Latin only? 1/2 4/5 1

Answers

The answer is going to be 4/5

The answer is 4/5 because the combined probability (French only is .5, and Latin only is .3) for French only and Latin only is .8, which is equal to 4/5.

Find all values of m so that the function y = e^mx
is a solution of the given differential equation. y' + 9y = 0

Answers

Hello,

y=e^(mx)
y'=m*e^(mx)

0=y'+9y=m*e^(mx)+9*e^(mx)
==> e^(mx)*(m+9)=0
This must be exact for every value of ,so
m=-9

Select all that apply.Which of the following expressions could you use to estimate 47% of 89?

1/2 · 90
0.5 · 90
0.47 · 89
90/2

Answers

Given:
47% of 89

Exact solution is : 0.47 * 89 = 41.83

Estimates: you round the number to the nearest tens.
47% can be 50% ; 89 can be 90

0.50 * 90 = 45

50% is the same as 1/2
1/2 * 90 = 45

90/2 is also applicable to estimate for the above figure. 90/2 = 45
