Answer:

52.4.

Step-by-step explanation:

This is the difference of 2 squares:

a^2 - b^2 = (a - b)(a + b)

(7.62^2 - (2.38)^2

= (7.62 - 2.38)(7.62 + 2.38)

= 5.24 * 10

= 52.4

Answer:

52.4

Step-by-step explanation:

a²-b² = (a-b)(a+b)

Similarly,

(7.62)²-(2.38)²

= (7.62-2.38)(7.62+2.38)

= (5.24)(10)

= 52.4

Two kids at a summer camp, Tina and Winston, are competing in a potato sack race. Tina is younger, so she is given a head start
agasfer [191]

Answer:

It will take Winston 11 seconds to hop 44 meters and catch up to Tina

Step-by-step explanation:

Set up an equation where x represents the number of seconds:

Tina will be represented by s + 33 since she goes 1 m/sec and she has a 33 meter head start, and Winston will be 4s. We need to find when Winston will catch up, so we need an equal sign.

s + 33 = 4s

Solve for s:

s + 33 = 4s

33 = 3s

11 = s

= 11 seconds

Then, plug in 11 as s to find how many meters he will go:

s + 33

11 + 33 = 44

= 44 meters
