Answer:
The larger circle area is 314 cm
The smaller circle area is 78.5 cm
Step-by-step explanation:
The formula for circles area is r^2×π
r is radius to the power or 2 then multiplied by 3.14
The big circle is 10 so 10 to the second power is 100
So 100×3.14=314
Therefore, the big circle's area is 314 cm
You do the same for the smaller circle
5 to the second power is 25
25×3.14=78.5
And for this reason the area of the smaller circle is 78.5 cm

The percentage of the cards Elin has finished is 72.5%.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Elin has made twenty-nine note cards for her friends. She plans to send out a total of forty cards.
Now, the percentage is
29/40 ×100

Answer:
72.5%
Step-by-step explanation:
(The total number of cards - 40 / Number completed - 29)
1. 40 = 100%
2. Divide both sides of the equation by 40 to get 1 on the right side (40/40 = 1) (100%/40 = 2.5%)
3. multiply both sides of the equation by 29 to find the percentage of cards completed (1*29 = 29 cards finished) (2.5%*29 = 72.5%)
4. Answer: Elin has completed 29 cards which is 72.5% of 40
B. 3h=17
C. 17h-3
D. 17h+3
Answer:
A. 3h+17
Step-by-step explanation:
Given,
The initial number of unloaded trucks = 17,
Also, 3 trucks per hour can be uploaded,
So, the additional number of uploaded truck after h hours = 3h,
Hence, the total number of uploaded trucks after h hours = Initial uploaded trucks + additional trucks
= 17 + 3h
Which is the required equation,
Option A is correct.
Answer:
A
Step-by-step explanation:
3 trucks per hour and you have already unloaded 17
