Answer:
you can use a calculator for this i think
Step-by-step explanation:
Total number of coins in question = 275
Number of quarters among the total coins = 120
Then
Remaining number of coins = 275 - 120
= 155
Percentage of coins that are nickel = 20%
Then
Number of coins that are nickel = (20/100) * 155
= 155/5
= 31
Remaining number of coins = 155 - 31
= 124
Ratio of dimes to pennies = 1:3
Let us assume the common ratio to be = x
Then
x + 3x = 124
4x = 124
x = 124/4
= 31
So
The number of pennies = 3 * 31
= 93
From the above deduction we can conclude that there are 93 pennies. The correct option among all the options given in the question is option "C".
Answer:
domain: all real numbers
range: y≥0
Step-by-step explanation:
This graph includes all real numbers for values of x (the domain), but only includes 0 and above for the y values (the range)
Hope this helps :)
