Answer:diameter=9.92m
Step-by-step explanation:
Area=77.28
π=3.14
Area=π x (d/2)^2
77.28=3.14 x (d/2)^2
Divide both sides by 3.14
77.28/3.14=(3.14x(d/2)^2)/3.14
24.6=(d/2)^2
Take them square root of both sides we get
d/2=√(24.6)
d/2=4.96
d=4.96 x 2
d=9.92

Answer:
36 boys
Step-by-step explanation:
3
Please write the ratio as 3:5 or as --------
5
Note that 3 + 5 = 8, so that the fraction of boys in the club is 3/8 and that of girls is 5/8.
How many are in the club altogether? Let this count be represented by c. Then (5/8)c = 60.
Multiplying both sides of this equation by (8/5), to isolate c, we get:
c = (8/5)(60) = 96. Thus, there are 96 Science students altogether.
3/8 of this number are boys. This comes out to (3/8)(96) = 36 boys.
We could also solve this problem in the following manner:
3 b
------ = ------- , where b represents the number of boys.
5 60
Then 5b = 180. Dividing both sides by 5, we get b = 180/5 = 36 boys
Answer:
She can make 27 bags
2 pieces of candy is left over
Step-by-step explanation:
She has 245 Chocolate Twisters.
she puts 9 Chocolate Twisters in each treat bag,
1 bag hold 9 chocolates
9 chocolates = 1 bag
So 245 chocolates in how many bags
Divide 245 by 9
use long division
2 7 -----------> Quotient
------------------------------------
9 245
18 (subtract it)
-------------------------
65
63 (subtract it)
----------------------------
2 -----------> remainder
She can make 27 bags
2 pieces of candy is left over
