Answer:
Option 1
Option 3
Option 4
Step-by-step explanation:
Inversely proportional means "one quantity increases, the other decreases" or "one quantity decreases, other increases". Inverse relationship, that's it.
Option1:
Since the volume is given as 56 and we know the volume is area of base * height, to keep the volume at constant [56], if height increases, area of base would need to decrease, and vice verse. So inversely proportional.
Option2:
The time spend in plowing a field with a tractor will increase when we area using more fuel. So more fuel used means more time spent. So these are directly proportional, NOT inverse.
Option3:
Since the price is at constant, the amount of length we buy more, the price per one yard HAS to decrease, and vice versa. So, this is inverse relationship.
Option 4:
If the number of identical tranctors increase, it will take less time to plow the set 358 acre farm. And vice versa. So this is inversely proportional as well.
Answer:
area is 26.75 units^2
Step-by-step explanation:
Top Triangle area is (3.5*9)/2=15.75
Square area is 2*2=4
Left bottom triangle is (2*2)/2=2
bottom right triangle is (2*5)/2=5
15.75+4+2+5=26.75
So, Noah would most likely have - wait hold up what's the main question?is it how much Noah has? if it is I will be able to solve it. Or is it how much water will fill it or something?
A) The formula for surface area of a sphere is A = 4*PI*r^2
using 3.14 for PI:
Surface area for Earth = 4 * 3.14 x 3960^2 = 196,960,896 miles^2
Surface area of the moon: 4 * 3.14 * 1080^2 = 14,649,984 miles^2
B)Divide the Surface of the Earth by the moon:
196,960,896 / 14,649,984 = 13.44
The Earths surface is 13.4 times larger than the moon.
C) Multiply the surface of the Earth by 70%:
196,960,896 * 0.70 = 137,872,627.2 million square miles of water.
