To Find the least common denominator you have to find the multiples of each number

multiple means the product of each factor

so the multiples of 4 would be 4 8 12 16 20

you want to name at least five multiples but if there are not the same multiples you might have to list more

the multiples of 5 would be 5 10 15 20

then I can stop there because I have found two of the same multiples

so now we have our least common denominator which is 20

HOPE THIS HELPS!!!

Jeremy ate 5 pieces of shrimp, Julie ate 7 pieces. What fraction of the total did Jeremy eat?
matrenka [14]

Answer:

\frac{5}{12}

Step-by-step explanation:

The total amount of shrimp that was eaten was 12 pieces of shrimp.

To make the fraction you will simply put the amount of shrimp Jeremy ate over the total number of shrimp eaten by the pair.

Therefore, the fraction would look like this:

\frac{5}{12}

The decimal form of this would be 0.4167. Which also means that Jeremy ate 41.67% of the total amount of shrimp eaten.

Hope this helps!!

Precal question please help I don’t understand
frez [133]

A) True.  The domain of both is: x ≥ 0

B) True. 1/2 is on the outside so it is vertical.  1/2 is between 0 and 1 so it shrinks.

C) False.  the coefficient is not 2 (it is 1/2)

D) False. 1/2 is not on the inside with "x" so it is not horizontal.

Answer: A, B

A zip line is setup 150ft in the air, where a person can expect to zip line at a safe declining speed to the ground as they pass
hichkok12 [17]

Answer:

139 ft

Step-by-step explanation:

So the zip line forms a right triangle.  The height of the triangle is 150 ft, and the opposite angle is 40°.  The horizontal distance covered by the zip liner can be found with trigonometry, specifically with tangent.

tan 40° = 150 / x

x = 150 / tan 40°

x ≈ 179 feet

But this includes the 40 ft long body of water, so the amount of ground covered is:

179 ft - 40 ft = 139 ft
