Answer:
3,200
Step-by-step explanation:
4000
3200 x 250 = 800,000 x 0.1 = 80,000
4000 x 250 = 1,000,000 x 0.1 = 100,000
4200 x 250 = 1,050,000 x 0.1 = 105,000
5000 x 250 = 1,250,000 x 0.1 = 125,000
28.8 and 180
you just times B by 2/5 to get C and divide it by 2/5 to get A
C = (72)(2/5) = 28.8 km³
A = (72)/(2/5) = 180 km³
We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.
60
Dividends are paid quarterly and it wants the annual amount, so you have to mulitply what you originally got by 4
or
75*.2*4=60
1/2 person
We can use a ratio to solve
6 rolls 1 roll
------------ = -------------
3 people x people
Using cross products
6x =3
Divide each side by 6
6x/6 = 3/6
x = 1/2
1 roll will solve 1/2 person
