Ethan’s cookie recipe uses 3 cups of sugar to make 21 cookies. Mia’s recipe uses 4 cups of sugar to make 24 cookies. Who's recipe has more sugar per cookie?

Answers

Alright, so ethan’s cookies would be 21 cookies per 3 cups of sugar. So you would do 21/3 to find you get 7 cookies per one cup of sugar

Then Mias cookies are 24 cookies per 4 cups of sugar. You would do 24/4 to get 6, so 6 cookies per cup of sugar.

Mia’s cookies make less cookies per cup of sugar, so they’d have more sugar in them.

Mia- 6:1

Nathan used 2(5/6) loaves of bread to make sandwiches for a lunch. He made equal numbers of 4 different types of sandwiches.
What fraction of a loaf of bread did Nathan use for each type of sandwich?

Answers

Answer:

A)

[tex]\displaystyle \frac{1}{12}[/tex]

B)

[tex]\displaystyle \frac{3}{5}[/tex]

C)

[tex]\displaystyle \frac{17}{24}[/tex]

Step-by-step explanation:

Part A)

The Hendersons were traveling 1/3 of the distance on the first day.

However, they had to stop, having only traveled 1/4 of the 1/3 distance.

So, we can multiply the two fractions together.

Therefore, the fraction of the total distance they traveled is given by:

[tex]\displaystyle \frac{1}{4}\times\frac{1}{3}=\frac{1}{12}[/tex]

The Hendersons traveled 1/12 of the total distance.

Part B)

We are assuming the bottle of milk was full at the beginning.

So, at the beginning, there were 1/1 bottle of milk left.

Howie fed a piglet 1/5 of the bottle. So, there is now:

[tex]\displaystyle 1-\frac{1}{5}[/tex]

Of the bottle left.

Making common denominators and subtracting yields:

[tex]\displaystyle =\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]

So, after feeding the piglet, 4/5 of the bottle of milk was still there.

3/4 of the remainder was fed to a calf.

So, the amount that was fed to the calf is 3/4 times 4/5. Therefore:

[tex]\displaystyle \frac{3}{4}\times\frac{4}{5}[/tex]

Multiply:

[tex]\displaystyle =\frac{12}{20}=\frac{3}{5}[/tex]

So, the calf drank 3/5 of the bottle of milk.

Part C)

Nathan used 2 (5/6) loaves of bread to make 4 sandwiches.

First, convert 2 (5/6) to an improper fraction. So:

[tex]\displaystyle 2\frac{5}{6}=\frac{12+5}{6}=\frac{17}{6}[/tex]

Nathan made 4 sandwiches using this. So, we will divide this by 4. Note that this is the same as multiplying by 1/4. Therefore:

[tex]\displaystyle \frac{17}{6}\times\frac{1}{4}=\frac{17}{24}[/tex]

So, Nathan used 17/24 loaves of bread per sandwich.

$92.81

$82.27

$59.91

Answers

Answer:92.81

Step-by-step explanation:

Answer:

$82.27

Step-by-step explanation:

First, figure out how much it would be without tax.

(2*16=32) + (3*2.50=7.50) + 37.75 = 77.25

Then, multiply this number by your tax rate.

77.25*6.5 = 5.02

Lastly, add your original total with this tax amount for your answer.

77.25+5.02= 82.27

9. The two figures below have a scale factor of 3 : 2. What is the value of x?

Answers

C I think hope this helps

The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.

The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.

Setting up the proportion, gives:

8/3 = x/2.

To solve for x,  cross-multiply:

[tex]8 \times 2 = 3 \times x.[/tex]

Simplifying the equation, gives:

16 = 3x.

Next, divide both sides of the equation by 3 to isolate x:

x = 16/3.

Therefore, the value of x is 16/3.
