Answer:
12.5 ft
Step-by-step explanation:
30 : x = 24 :10
30*10 = 24x
x= 300/24 =12.5
I am hoping that the a in c = ad is supposed to be x.
The formula for circumference is c = pi * diameter with 3.14 substituting for pi.
Let’s plug in some values
172.7 = 3.14d
Divide
55 = d
The diameter should be 55 cm.
Answer:
<h2>There are 13 quarters, 5 nickels and 20 dimes.</h2>
Step-by-step explanation:
Givens
- Max has $5.50.
- He has eight more quarters than he does nickels.
- He had four times as many dimes as he has nickels.
From these statements, we can deduce algebraical expressions to solve the problem. Let's call
quarters,
nickels and
dimes.
(8 more quarters than nickels)
(he has four times as many dimes as he has nickels).
(Max has a total of $5.50, one quartes is $0.25, one nickel is $0.05 and one dime is $0.10).
Let's replace the first two expressions into the third equation

There are 5 nickels.
Now, we use this value to find the number of quarters

There are 13 quarters.
Also, 
There are 20 dimes.
Therefore, there are 13 quarters, 5 nickels and 20 dimes.
Answer:
Step-by-step explanation:
54 equals 9 more than a number
So if we do this, we get
54 = x+9
x+9 = 54
54-9=x
54-x = 9
About 190% because its almost two times the original number
