Answer:
<em>The elephants' moat should be 3.2 meters deep.</em>
Step-by-step explanation:
Suppose, the depth of the elephants' moat is
meter.
Width of the lions' moat is 5 meter and width of the elephants' moat is 4 meter.
Given that, the lion’s moat is 4 meter deep.
So, <u>according to the ratio of width and depth</u>, the equation will be.......

Thus, the elephants' moat should be 3.2 meters deep.
Answer:
Step-by-step explanation:
If she travels by air, she will be able to work seven hours in D.C. work four hours once there. Her expected income from each hour of work in D.C. is $40. This means that the total amount that she earns in 7 hours would be
40 × 7 = $280
if she drives, she will only have time to work four hours once there. This means that the total amount that she earns in 4 hours would be
40 × 4 = $160
The difference in both amounts would be
280 - 160 = $120
she will chose to fly if and only if the price differential (air cost minus driving cost) is less than $120
The first step you should do is subtract 32 from both sides so your answer will turn out like this -
F = (9/5) C + 32
-
F - 32 = (9/5)
Then we will multiply both sides by 5.
5 ( F - 32 ) = 9 C
Divide both sides by 9 to isolate C.
(5/9) ( F - 32 ) = C
So the answer is :
C = (5/9) ( F - 32 )
