Answer:
FE
Step-by-step explanation:
The radius of a circle is the line segment from the centre of the circle to a point on the circle.
F is the centre of the circle, thus
FA, FE, FD, FC and FB are all radii of the circle
Answer:C
Step-by-step explanation: In order for it to become the second figure it needs to be enlarged and reflected. It needs to be enlarged first so it will end up placed in the right spot.
Part (a)
<h3>Answer: 0.2</h3>
----------------------------------
Work Shown
It costs $15 to rent a bike for 3 hours. We can write the following ratio below
15 dollars : 3 hours
To represent the connection of the two concepts (dollars connecting with hours)
We want the "15 dollars" to turn into "1 dollar". This is because the phrasing "per dollar" really means "per 1 dollar".
Divide both sides of the ratio by 15 to achieve this goal.
15 dollars : 3 hours
15/15 dollars : 3/15 hours
1 dollar : 1/5 hours
1 dollar : 0.2 hours
0.2 hours : 1 dollar
So we get 0.2 hours per dollar.
As a side note, 0.2 hours = 0.2*60 = 12 minutes.

Part (b)
<h3>Answer: 3.38</h3>
----------------------------------
Work Shown
27 pages : 8 minutes
27/8 pages : 8/8 minutes
3.375 pages : 1 minute
3.38 pages : 1 minute
I'm dividing both parts of the original ratio by 8 to turn "8 minutes" into "1 minute" (due to the phrasing "per minute"). Don't forget to round to 2 decimal places.
Answer:
The cost is $352.80
Step-by-step explanation:
step 1. 14 * 12 = 168 ----> find out the area (base times height)
step 2. 168 * 2.10 = 352.80 -----> multiply the area with the cost of per square foot of the carpet
I hope this helped :))
