Answer:
The ratio of zacharies nickels to dimes to quarters is <u>3 : 2 : 1</u>.
Step-by-step explanation:
Given:
Zachary has coins of the coins 3/6 are nickels, 2/6 dimes, rest are quarters.
Now, to get the ratio of zacharies nickels, to dimes to quarters.
So, as given dimes and nickels we find the quarters to get the ratio:
.
Thus, the quarters are 1/6.
Now, getting the ratio of the coins:
Nickels = 3/6 × 6 = 3
Dimes = 2/6 × 6 = 2
Quarters = 1/6 × 6 = 1
<em>Nickels : Dimes : Quarters = 3 : 2 : 1.</em>
Therefore, the ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.
Answer:...
Step-by-step explanation:
Step-by-step explanation:
Part (a):
Since new payment amount is 20% less than the original, we can write
New Earning = N
= $18 - (20%) ($18)
N
= (80%)($18)
N
= 0.8 * 18
N
= $14.4
Part (b):
New number of errors are one-third (
) of the initial 15 errors,
Therefore, new number of errors = E = 
E = 
E = 5
It is given that, earnings per error = n = 15 cents = $0.15
Thus, we can calculate the total earnings for new number of errors as follows,
New Total Earning = N
= n * E
N
= 0.15 * 5
N
= $0.75
