Hello!
We know that Isaac played 20 games and won about 70% of them. Now, we must find what 70% of 20 is, so that we know how many games Isaac won.
First, convert the percentage to a decimal by dividing it by 100.
70% ÷ 100 = 0.70
Next, multiply the total amount of games Isaac played (20) by about how many he won (0.70):
20 × 0.70 = 14
ANSWER:
Isaac won about 14 games.
I believe it’s b I am not sure
Step by step explanation
Amanda Billy
1st week 10 5
2nd week 20 10
3rd week 30 20
4th week 40 40
<span>
A) Amanda's method is linear because the number of minutes increased by an equal number every week.</span>
common difference is 10.
1st week 0 + 10 = 10
2nd week 10 + 10 = 20
3rd week 20 + 10 = 30
4th week 30 + 10 = 40
Billy's method is exponential:
5(2)^x
1st week 5(2⁰) = 5(1) = 5
2nd week 5(2¹) = 5(2) = 10
3rd week 5(2²) = 5(4) = 20
4th week 5(2³) = 5(8) = 40
All angles are of triangle and thus give sum of 180⁰
x + 5 + 7x - 5 + x = 180⁰
9x = 180⁰
x = 20⁰
Answer:
4,318÷7= 617
I have already rounded the decimal to make it into a whole.
