Emma says the GCF of 16 and 12 is 48. Her friend Grace says the answer is 4. Who is right?

The new average will be 89.55%.

What is an average?

The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.

It is given that,

Average score after 8 tests = 91%.

Therefore, Total score of 8 tests = Average score*Number of tests

Total score of 8 tests = 91*8

Total score of 8 tests = 728

Now, Cory scored 78% in 9th test,

So, Total score of 9 tests = Total score of 8 tests + 78

Total score of 9 tests =  728 + 78

Total score of 9 tests = 806

Hence, Average score of 9 test =  Total score of 9 tests/9

Average score of 9 test = 806/9

⇒ Average score of 9 test = 89.55%

Hence, the new average will be 89.55%.

Hey there!

3/4 + 1/12 + 2/3

= 5/6 + 2/3

= 5/6 + 4/6

= 5 + 4 / 6

= 9 / 6

= 9 ÷ 3 / 6 ÷ 3

= 3/2
≈ 1.5

1.5 - 1 = 0.5

Therefore, your answer is: 0.5

Good luck on your assignment & enjoy your day!

Answer:70/100

Step-By-Step:

Well you should simplify 70/100 which would be 7/10, so now that is a decimal and will move one step to the left which is 0.7 in decimal form

Answer:

The following system of equations represents the situation:

0.2h + 0.1s = 2

s + h = 15

Step-by-step explanation:

Hi there!

The total amount of yarn is 2 kg and we know that each hat uses 0.2 kg yarn and each scarf uses 0.1 kg. Then, the amount of yarn used per hat times the number of hats made, plus the amount of yarn used per scarf times the number of scarves made will be 2 kg.

h = number of hats

s = number of scarves

0.2h + 0.1s = 2

We also know that the total quantity of items made is 15, then, the number of hats plus the number of scarves will be 15:

s + h = 15

Then, we obtain the following system of equations:

0.2h + 0.1s = 2

s + h = 15

Only for curiosity, let´s solve the system:

Solve for h in the second equation:

h = 15 - s

Replace h in the first equation:

0.2(15 - s) + 0.1s = 2

3 - 0.2s + 0.1s = 2

-0.1s = -1

s = -1/-0.1

s = 10

Then, h = 5

Answer:

0.2h + 0.1s = 2

h + s = 15
