What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that  cookie contains 9 grams of fat and eat no fewer than 4 and no more than 7 cookies, then;

Since each cookie has 9 grams of fat, four cookies would be;

4 x 9 = 36 grams of fat.

Also, the nine cookies have 7 x 9 = 63 grams of fat.

Therefore, the number of grams consumed will be; at least 36 and no more than 63.

For Judy's birthday, her friends gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clothing. Judy used all of the money on the gift card to pay for part of the total. She paid the remaining $71.30 with cash. Which percentage best describes the part of the total Judy paid for with the gift card?

Answers

Answer:

60%

Step-by-step explanation:

Firstly, we want to solve for the amount on the gift card

the total cost is $178.25

the cash payment is  $71.30

then the value of the gift card is

=$178.25- $71.30

=$106.95

Therefore the percentage of the gift card to the total pay is

=(106.95/178.25)*100

=0.6*100

=60%

How does transformation of a function happens?

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

WE are given that AB is rotated 120° clockwise about B.

AB is rotated 120° clockwise about B. Then AB  is rotated 45° counterclockwise about A.

It is rotated 120° clockwise and clockwise is negative and the other is rotated 45° counterclockwise and counterclockwise is positive.

A ratio shows us the number of times a number contains another number.

Since For every 5 hardcover books a teacher buys, he or she can get 2 paperback books for free. Therefore, the ratio of hardcover books to paperback books will be,

Hardcover/paperback = 5/2

Using the same ratio for 35 hardcover books,

35/Paperbook = 5/2

(35×2)/5 =Paperbook

Paperbook = 14

Hence, the number of paperback books Ms. Baldwin get for free is 14.
