Answer the following questions.
(a) What percent of 80 is 44?
(b) What number is 45% of 40?
Answer:
a. 55%
b. 22
Step-by-step explanation:
Answer:
[tex]a)55[/tex]
b) 18
Step-by-step explanation:
→ Set up an for part a
[tex]\frac{80x}{100} =44[/tex]
→ Multiply both sides by 100
[tex]80x=4400[/tex]
→ Divide both sides by 80
[tex]x = 55[/tex]
→ Multiply both numbers together for part b
45 × 40 = 1800
→ Divide the answer by 100
1800 ÷ 100 = 18

hannah is making maffins. The recipe calls for 5/8 cup of milk to make 20 muffins. What is the unit rate for cups of milk per muffins? For muffins per cup of milk?
Answer:
32 muffins
Step-by-step explanation:
one cup of milk will make 32 muffins
you can set up a proportion of milk/muffins = milk/muffins
let 'x' = number of muffins made from one cup of milk
5/8 ÷ 20 = 1 ÷ x
cross-multiply to get 5x = 20(8)
5x = 160
x = 32

Hanna and Dien are both getting a raise. Who will earn more
per hour after the raise?
Step-by-step explanation:
First, you need to calculate how much they will earn per hour by multiplying their raise per hour by there hours and adding it to their earnings divided by the hours worked. Then, whoever's is the highest will be the answer.
Hanna will earn more per hour after the raise, with an hourly rate of $10.75 compared to Dien's hourly rate of $10.60.
What is Division?A division is a process of splitting a specific amount into equal parts.
To find the new earnings per hour for Hanna and Dien
Divide their total earnings after the raise by the total number of hours they worked after the raise.
The raise per hour is already given, so we can simply add it to their old hourly rate.
For Hanna, her new hourly rate would be:
(New earnings) / (Hours worked) = (78 + 8) / 8
= 86 / 8
= $10.75
This means that Hanna will earn $10.75 per hour after the raise.
For Dien, his new hourly rate would be:
(New earnings) / (Hours worked) = (60.60 + 3) / 6
= 63.60 / 6
= $10.60
This means that Dien will earn $10.60 per hour after the raise.
Therefore, Hanna will earn more per hour after the raise, with an hourly rate of $10.75 compared to Dien's hourly rate of $10.60.

HELPPP LAST ATTEMPT!!
Answer:
Here’s something I wrote that can help you. I don’t really wanna do transformations but this should help you get the answer in a snap.
ONLY FOR REFLECTIONS
Over the x-axis: (x, y) — > (x, –y)
Over the y-axis: (x, y) — > (–x, y)
Over the line y = x: (x, y) — > (y, x)
Through the origin: (x, y) — > (–x, –y)
So for example E is (6,-1)
Over the y axis so following the coordinate plane rules, (6,-1) — > (-6, -1)
(-6, -1) over x axis which is following the rules
(-6, -1) — > (-6, 1)
Final answer (-6,1)
Answer:
(-6, 1)
Step-by-step explanation:
If you reflect over y-axis and x-axis it is just the opposite of each number.

For any right triangle, the sum of the sqaures of the legs is equal to the square of the hypotenuse
Answer:
Pythagorean Theorem. The Pythagorean theorem states that in any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs of the right triangle. This same relationship is often used in the construction industry and is referred to as the 3-4-5 Rule.
