Answer:
3:45 pm
Step-by-step explanation:
Every 90 degree = 15 minutes
270 degrees = 15 x 3 = 45 minutes
3:00 + 0:45 = 3:45 pm
Hope this helps!
Answer:
The correct ratio is 7:8, so no, Emma is not correct.
Step-by-step explanation:
The height of the swipe card is given by :
.....(1)
We need to find the maximum height of the swipe card and the time to reach the maximum height.
For maximum height, put dh/dt = 0
So,

It will take 1.67 seconds to reach the maximum height.
Now, put t = 1.67 s in equation (1).

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.

Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55
