Mathematics
1 answer:
EastWind [94]3 years ago
3 0

Answer:

2 1/4 cups

Step-by-step explanation:

the first step is to determine how many cups would be needed for 1 pancake

1 1/4 ÷ 8

5/4 x 1/8 = 5/32 cups

the second step is to determine how many cups would be needed for 40 pancakes

5/32 x 40 = 25/4 = 6 1/4

The next step is to convert quart to cups

1 quart = 4 cups

So Maria has 4 cups of milk.

the cups she needs more = 6 1/4 - 4 = 2 1/4 cups

I need help with this by Wednesday Please Help!!!!!
GuDViN [60]

Answer:

Step-by-step explanation:

To complete the given table we will substitute the output value to calculate the input value.

Given function is,

y = 2x + 4

For output value, y = 18

18 = 2x + 4

2x = 18 - 4

x = 7

For output value, y = 22

22 = 2x + 4

2x = 22 - 4

x = 9

For output value, y = 34

34 = 2x + 4

2x = 34 - 4

2x = 30

x = 15

Therefore, table will be,

       Input (x)                 y = 2x + 4                output

          7                                                              18

          9                                                             22

         15                                                             34

The label on the paint container states that its average​ coverage rate is 275 square feet per gallon. ​What is the​ difference
Katen [24]

Answer:

  • <u><em>The rate of paint coverage of Angela is 13ft²/gallon less than the average rate indicated on the label of the container.</em></u>

Explanation:

This question is the second part (Part B) of a two-parts question.

You need solve the first part first, to use the result as input of this second part.

Please, find attached the whole question.

<u>Part A. Angela's rate of paint coverage</u>

          \text{Rate of paint coverage}=\frac{\text{gallons of paint used}}{area}

Convert the mixed numbers to improper fractions:

        42\frac{2}{3}=42+\frac{2}{3}=\frac{3\times 42+2}{3}=\frac{128}{3}          [this is square yards]

        1\frac{1}{3}=1+\frac{1}{3}=\frac{3\times 1+1}{3}=\frac{4}{3}                  [this is gallons]

Now calculate the rate:

\frac{\frac{128}{3}}{\frac{4}{3}}=\frac{128}{3}\times \frac{3}{4}=\frac{128}{4}=32          [that is square yards per gallon]

Part. B.

To compare the rates first change 32 yard²/gallon to feet²/gallon.

           1 yd^2=9ft^2\implies 1=9ft^2/1yd^2\\ \\ 32yd^2/gallon\times 9ft^2/1yd^2=288ft^2

<h2>Difference:</h2>

  • 288 ft²/gallon - 275ft²/gallon = 13ft²/gallon

Help? I will post another one in a sec
mafiozo [28]
Okay so take:

3.99×3=11.97 that's how much the magazines cost together

add the tax which is 1.02→ 11.97+1.02=12.99

12.99 is how much the tax and magazines were now you need to add the four sheets of stickers and add the coupon because the total was more and the total was 16.49 with the coupon and without it its 17.99

take 17.99-12.99=5.00 and divide that by 4 and your answer is 1.25

EACH SHEET OF STICKERS COST 1.25 EACH
