Answers

Answer 1
Answer: greatest common factor is found by finding the factors of each
factors48=2 times 2 times 2 times 2 times 3
78=2 times 3 times 13
find common group
comon group=2 times 2=6
gcf=6
find others
narrow it down by crossing out any choices with numbers not divisible by 6
(crosses out A,B,C since A has 4 and B has 8 and C has 9)

therefor the answer is D, 12 and 18
check
12=2 times 2 times 3
18=2 times 3 times 3
common group=2 times 3=6
correct

answer is D, 12 and 18

1. At a refreshment stand, 73% of the beverages are cold and 43% of the beverages are caffeinated. Of the total beverages at the refreshment stand, 37% are cold caffeinated beverages. Beverages are only hot or cold and caffeinated or decaffeinated. What percentage of the total beverages are hot decaffeinated beverages?

Answers

Answer:

Therefore, 94% of the total beverages are hot decaffeinated beverages.

Step-by-step explanation:

Let's break down the information given step by step to find the percentage of hot decaffeinated beverages:

73% of beverages are cold.

43% of beverages are caffeinated.

37% of beverages are cold and caffeinated.

To find the percentage of hot decaffeinated beverages, we can first find the percentage of cold caffeinated beverages, and then use that information to find the percentage of hot caffeinated beverages.

Percentage of cold caffeinated beverages = Percentage of beverages that are both cold and caffeinated = 37%

Now, let's find the percentage of hot caffeinated beverages:

Percentage of hot caffeinated beverages = Percentage of caffeinated beverages - Percentage of cold caffeinated beverages = 43% - 37% = 6%

Since beverages are only hot or cold and caffeinated or decaffeinated, the sum of the percentages of hot and cold caffeinated beverages should be equal to the total percentage of caffeinated beverages:

Percentage of hot caffeinated beverages + Percentage of cold caffeinated beverages = Percentage of caffeinated beverages 6% + 37% = 43%

Now, let's find the percentage of hot decaffeinated beverages:

Percentage of hot decaffeinated beverages = 100% - Percentage of hot caffeinated beverages = 100% - 6% = 94%

Therefore, 94% of the total beverages are hot decaffeinated beverages.

Step-by-step explanation:

Let's look at this question step by step.

Cold and hot beverages.

--> 73% and 27%

Caffeine or decaffeinated

--> 43% and 57%

Then it has said that 37% are cold caffeinated beverages.

Which means 100% minus 37% would be 63%.

Answer is 63%.

Katie has read 32% of a book. if she has read 80 pages, how many more pages does Katie have left to read ?

Answers

Hi

100%-32% = 68%

32% ⇒ 80 pages
68% ⇒ x pages

32x = 80·(68)
32x = 5440
x = 5440/32
x = 170 pages left to read

Answer: 170 pages

Answer:

Step-by-step explanation:

x=total number of pages.

1)we calculate the total number of pages.

32% of x =80

(32/100)x=80

x=(80*100)/32

x=250.

2) we calculate the number of pages don´t read.

number of pages don´t read=250-80=170  

Answer: 170 pages.

Answer : x= 1 3/7
-1(x + 2) = 2(3x - 6)

First, simplify 1 × (x + 2) to (x + 2) / Your problem should look like: -x - 2 = 2(3x - 6)
Second, expand. / Your problem should look like: -x - 2 = 6x - 12
Third, add x to both sides. / Your problem should look like: -2 = 6x - 12 + x
Fourth, simplify 6x - 12 + x to get 7x - 12. / Your problem should look like: -2 = 7x - 12
Fifth, add 12 to both sides. / Your problem should look like: -2 + 12 = 7x
Sixth, add -2 + 12 to get 10. / Your problem should look like: 10 = 7x
Seventh, divide both sides by 7. / Your problem should look like: (10)/(7) = x
Eighth, switch your sides. / Your problem should look like: x = (10)/(7)

Answer: x = (10)/(7)
