Question says to find the square root of 3.24.
To find square root of decimal numbers, we can start by converting them into fraction so that decimal gets removed then find square root of numerator and denominator separately.
there are two digits after decimal in 3.24 so we can rewrite 3.24 as 324/100
Now let's find square root of the resulting fraction
Hence final answer is 1.8.
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.
