Answer:

219 ft, 9 inches

Step-by-step explanation:

73.25 yards of cable to feet and inches

1 yard = 3 ft

Therefore;

73.25 yards is equal to;

73.25 x 3 = 219.75 ft

1 ft =12 inches

Thus; 0.75 ft is equal to;

0.75 × 12 =9 inches

Hence; 73.25 yards is equal to 219 ft and 9 inches

A jar is filled with only dimes and quarters. The jar contains a total of 60 coins and the value of the jar is $11.25. How many

inessss [21]

Answer:

35 quarters

Step-by-step explanation:

This situation has two unknowns - the total number of dimes and the total number of quarters. Because we have two unknowns, we will write a system of equations with two equations using the two unknowns.

$d+q=60$ is an equation representing the total number of coins
$0.10d+0.25q=11.25$ is an equation representing the total value in money based on the number of coin. 0.10 and 0.25 come from the value of a dime and quarter individually.

We write the first equation in terms of q by subtracting it across the equal sign to get $d=60-q$ . We now substitute this for d in the second equation.
