Greeley [361]

The answer is 6.4 x 8 in.

The scale 5 : 4 means that the old photo is 5 and the new photo is 4.
Now, let's find the new dimensions using the proportion for each side separately.

5 : 4 = 8 : x
x = 4 * 8 : 5
x = 6.4 in
_____
5 : 4 = 10 : y
y = 4 * 10 : 5
y = 8 in

Jake had a piggy bank dipped with nickels quarters and dimes. He noted that he had three times as many dimes as quarters and fou

prohojiy [21]

Answer:

There are 72 dimes having a total value of $7.2.

Step-by-step explanation:

Let the number of dimes be 'd', nickels be 'n' and quarters be 'q'.

Given:

Number of dimes is three times quarters

Number of nickels is four less than twice the number of dimes.

Total amount in the piggy bank is $20.20

Now, as per question:

Number of dimes is three times quarters

Framing in equation form, we get:

$d=3\times q\\d=3q\\q=\frac{d}{3}---1$

Number of nickels is four less than twice the number of dimes.

Framing in equation form, we get:

$n=2d-4----2$

Now, value of 1 dime in dollars is 0.1.

Value 'd' dimes = $0.1d ----------(A)

Value of 1 quarter = $0.25

Value of 'q' quarters = $0.25q ----------(B)

Value of 1 nickel = $0.05

Value of 'n' nickels = $0.05n ----------(C)

Now, total amount is equal to the sum of all the amounts of each type of coin.

So, adding equations (A), (B) and (C) and equating to 20.20, we get:

$0.1d+0.25q+0.05n=20.20$

Now, using equations (1) and (2), the above equation can be rewritten as:

$0.1d+0.25(\frac{d}{3})+0.05(2d-4)=20.20\\\\0.1d+\frac{d}{12}+0.1d-0.2=20.20\\\\d(0.1+0.1+\frac{1}{12})=20.20+0.2\\\\0.2833d=20.40\\\\d=\frac{20.40}{0.2833}=72$

So, there are 72 dimes in the piggy bank.

Total value of 72 dimes = 72(0.1) = $7.2
