The school’s fish eat 1/5 jar of food per day. How many days will 4 1/2 jars feed them? Possible answers : 22 1/2days, 21 days, 21 1/2 days, 22 days

22 1/2 days

Step-by-step explanation:

All you gotta do is divide!

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
