A recipe for cookies calls for

A.

B.

C.

Answers

The answer is B.) you will need 3 cups of chocolate chips

For 7 dozens cookies 3 1/2 cups needed.

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

For 3 dozen cookies = 1 1/2 cups = 3/2 cups

For 1 dozen cookies = 3/2 * 1/3 = 1/2 cups needed

So, for 7 dozen cookies = 1/2 * 7

                                       = 3 1/2 cups needed

Hence, for 7 dozens cookies 3 1/2 cups needed.

Answer:  4955.30

Step-by-step explanation:

F = P (1+i)^n

F = $4000 (1+.055)^4

F = $4955.2986

Which will be 4955.30

Answer:

A. $4955.30

Step-by-step explanation:

Look at the equation

A(t)= P(1+r)^t

In this equation,

A(t) is your amount after a period of time,

P is the initial balance stated in the question (4000)

r is the rate (must be converted to a decimal) as stated in the question (0.055)

t represents the amount of time that has passed (4 years)

Whenever you plug this into the equation, you get

A(t) = 4000(1.055)^4 and this can be plugged into a calculator to get your answer which will be

4955.29 (round up to .3) and your final answer is A. 4995.30

In order to convert from percent to decimal you just need to move the decimal to the left two places

5.5 becomes 0.055 after the decimal is shifted

Answers

Answer:

x = 60

Step-by-step explanation:

So, ever triangle, no matter what shape or size, is always going to equal 180 degrees. You start off by trying to find angle L which is 71. The way you find this is you subratch 109 from 180 which ultimately gives you 71.

180 - 109 = 71

After that you have to add what you already have (49 degrees) with what you just found (71 degrees)

49 + 71 = 120

Now that you have 120, you have to again subtract 180 by 120 to get your answer, 60 degrees. And that's it.

180 - 120 = 60
