Which is bigger? 1/3 foot or 5 inches? It can also be equal.
zhannawk [14.2K]

5 inches is bigger than 1/3 foot OR 1/3 foot is lesser than 5 inches. That is, 1/3 foot < 5 inches

4 miles is bigger than 7000 yards. That is, 4 miles > 7000 yards

8 yards is equal to 24 feet. That is, 8 yards = 24 feet

<h3>Calculating the value of a quantity </h3>

From the question, we are to determine which of the given quantities are bigger or equal

  • 1/3 foot or 5 inches

NOTE: 1 foot = 12 inches

If 1 foot = 12 inches

Then,

1/3 foot = 1/3 × 12

1/3 foot = 4 inches

∴ 5 inches is bigger than 1/3 foot. That is, 1/3 foot < 5 inches

  • 4 miles or 7,000 yards.

NOTE: 1 mile = 1760 yards

If 1 mile = 1760 yards

Then,

4 miles = 4 ×1760 yards

4 miles = 7040 yards

Hence, 4 miles is bigger than 7000 yards. That is, 4 miles > 7000 yards  

  • 8 yards or 24 feet

NOTE: 1 yard = 3 feet

If 1 yard = 3 feet

Then,

8 yards = 8 × 3 feet

8 yards = 24 feet

Hence, 8 yards is equal to 24 feet. That is, 8 yards = 24 feet

if you drop a tennis ball from the height of 100in and the rebound is 58in what is the height on the 10th bounce?
xenn [34]

Answer:

0.431 inches

Step-by-step explanation:

We were given the following values:

Height the tennis ball was dropped = 100in

Rebound height = 58in

We have to find the rebound ratio

= 58in/100in = 0.58

The formula to be used

Height on nth bounce = Initial height × (Rebound ratio)ⁿ

Where n = number of bounce

Height on the 10th bounce = 100 × (0.58)^10

Height on the 10th bounce = 0.4308042069inches

Approximately, the height on the 10th bounce = 0.431 inches.
