Answer:
There would be 24 dimes and 76 quarters.
Step-by-step explanation:
In order to find this, start by defining the number of dimes by x and the number of quarters as y. Now we can create a system of equations. Make the first about the total number of coins.
x + y = 100
Make the second about the amount of money.
.10x + .25y = 21.40
Now we can solve using elimination by multiplying the second equation by -4 and adding through.
x + y = 100
-.40x - y = -85.60
-----------------------
.60x = 14.4
x = 24
Now we can use the amount of dimes we have to find the number of quarters.
x + y = 100
24 + y = 100
y = 76
Given;
ABCDE is similar to VWXYZ
so, the corresponding segments are proportional
We need to find the length of XY
XY is corresponding to CD
CD = 1.2 cm
Finding another two corresponding sides
DE = 3.2 cm , YZ = 4 cm
so,
So, the length of XY = 1.5 cm
