Answer:
7/40 feet
Step-by-step explanation:
Solve using proportions:
Find the scale factor by dividing the numerators 25 by 1/8.
25 ÷ 1/8 = 200 This is the common ratio
To get from the top left number to the top right number, you divide 25 by 200.
To get from the bottom left number to the bottom right number, you divide 35 by 200.
35 ÷ 200 = 0.175
1/8 of an inch represents 0.175 feet.
To find 0.175 in fraction form, reduce 35/200 to its lowest terms.
35/200 = 7/40
1/8 of an inch represents 7/40 feet.
This question is solved using a system of equations, and doing this, we get that: There are 9 quarters, 4 nickels and 12 dimes.
I am going to say that:
x is the number of nickels.
y is the number of dimes.
z is the number of quarters.
In all, they are worth $3.65.
A nickel is worth $0.05, a dime is worth $0.1 and a quarter is worth $0.25, so:
Dimes: 3 times greater than nickels:
This means that:
Quarters: One greater than double the number of nickels:
This means that:
Value of x:
We have y and z as function of x, so we can replace into the equation and find the value of x, so:
y and z:
There are 9 quarters, 4 nickels and 12 dimes.
