The answer is D because the temperature between 7:00 am and 9:00 am is decreasing by 5
Solution:
<u>Note that:</u>
<u>Use the equation above to solve for t.</u>
- 5t - 8 + 68 = 180
- => 5t + 60 = 180
- => 5t = 180 - 60
- => 5t = 120
- => t = 120/5 = 24
The value of t is 24.
Answer: She's wrong.
Step-by-step explanation:
Numbers of hours used in solving homework last week = 15
Numbers of hours used in solving homework this week = 18
Percentage increase = (18 - 15) / 15 × 100
= 3/15 × 100
= 1/5 × 100
= 20%
Since Maxie said that she spent 120% more time doing homework this week, she's wrong. She only spent 20% more.
Perimeter = (length+width) x 2
Let w units be the width of the rectangle.
Length of the rectangle = 2w
Perimeter:
(2w+w) x 2 = 60
(3w)2 = 60
6w = 60
w = 10
Area:
2(10) x 10
= 20 x 10
= 200 units
