Answer:

10 days

Step-by-step explanation:

We are given that

Each person takes 56 days

7 painters take time=56\times 7=392 painter days

In first 6 days , 7 painters take time=7\times 6=42painter days

After 6 days , 28 volunteers are added then,

Total persons=28+7=35

Now, remaining days=392-42=350

Therefore, number of days are required before the painting of the king of rock 'n' roll is completed=\frac{350}{35}=10days

Hence,10 more days are required before the painting of the king of rock 'n' roll is completed

Distribute the 4 on the right side

36=4(h+2)

36=4h+8

Subtract 8 on both sides

28=4h

Divide by 4 on both sides

h=7

PLEASE HELP

You don't say whether this is a right triangle or not.

Assuming it is a right triangle, then we use the Pythagorean Theorem to determine the length of the hypotenuse:

(hypo) = (length of third side) = √(12^2 + 4^2) = √(144+16) = √160 = 4√10.

This is approx. 12.65 inches. Since this does not match any of the possible answer choices, we'll have to take a different approach to answering this question.

Given that 2 sides of the given triangle are 12 and 4 inches, respectively, we see that the 3rd side has to be longer than 8 inches; otherwise we'd have three line segments on the same line, not forming a triangle.

By this reasoning, 9 inches is the only possible answer that could be correct. With sides 12, 9 and 4 inches, the triangle would be obtuse and appear quite flat, but not be part of a straight line as with a third side of 8.

How many whole servings of 3/4 cups are in 3 1/2 cups of ice cream?
Kisachek [45]
Well, what you're going to do is.. turn 3 1/2 into an irregular fraction.

3 = 6/2
we still have the initially 1/2 left so we will add that.
7/2

now we want to change it so that the denominator is equal to 4 so we multiply both top and bottom by 2

14/4

now we divide the 14 by 3 and you will get approximately 4. we will ignore the rest because it asks for whole servings and 3 only goes nicely into 14 4 times
