There are 62 quarters and 52 dimes in the jar.
Step-by-step explanation:
Given,
Worth of jar coins = $20.70 = 20.70*100 = 2070 cents
1 Quarter = 25 cents
1 Dime = 10 cents
Let,
Number of quarters = x
Number of dimes = y
According to given statement;
25x+10y=2070 Eqn 1
x=y+10 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 35
Putting y=52 in Eqn 2
There are 62 quarters and 52 dimes in the jar.

Answer:
2290 steel balls weigh 3,180 grams so each ball weighs 1.3886462882
grams. If you had a 8.87 kilograms of those balls they would number
8,870 grams / 1.3886462882 = 6,388 steel balls

Step-by-step explanation:
To find the average amount of rain, take the total amount of rain and divide by the time
7 inches / 24 hours
7 /24 inch per hour
I believe this is scale factor? SF=new/old. 10/8= a scale factor of 1.25 (the image gets 1.25x bigger). To find x, multiply 5 by 1.25 and subtract the original length of 5 (you subtract this length because x is only the value of the new part of the triangle). X=6.25-5, X=1.25. Try to find y yourself using this scale factor. (Brainliest would be appreciated)
