Answer:
x > 8
Step-by-step explanation:
Given
17 < 9 + x ( subtract 9 from both sides )
8 < x , hence
x > 8
A = 1/2 BH
#17
B = 3 H = 4
A = 1/2 BH
A = 1/2 (3)(4) = 6
#18
B = 6 H = 4
A = 1/2 BH
A = 1/2 (6)(4) = 12
#19
B = 12 H = 8
A = 1/2 BH
A = 1/2 (12)(8) = 48
#20
B = 11 H = 5
A = 1/2 BH
A = 1/2 (11)(5) = 27.5
Paul must get 13 since Peter gets more more than Jane so Jane would get 7 and then peter would get 12
Answer:3*78=234
Step-by-step explanation:
Answer:
Step-by-step explanation:
- 1) Total points = 25
- 2) Points earned = 21
- 3) Percent score = 84%
<u>Proportion:</u>
Solving the others in the table
<u>21 out of 25 points:</u>
- 21/25 = x/ 100 ⇒ x = 100*21/25 = 84
<u>15 out of 20 points:</u>
- 15/20 = x/100 ⇒ x = 100*15/20 = 75
<u>47 out of 50 points:</u>
- 47/50 = x/100 ⇒ x = 100*47/50 = 94
<u>28 out of 30 points:</u>
- 20 / 30 = x/100 ⇒ x = 100*20/30 = 66.66
<u>19 out of 45 points:</u>
- 19/45 = x/100 ⇒ x = 100*19/45 = 42.22
<u>3 out of 4 points:</u>
- 3/4 = x/100 ⇒ x = 100*3/4 = 75
