Express each ratio as a unit rate. round to the nearest tenth, if necessary. 400 feet in 52.4 seconds

7.6 ft/sec

Step-by-step explanation:

Given : 400 feet in 52.4 seconds

To Find : Express each ratio as a unit rate.

Solution:

Distance = 400 feet

Time = 52.4 seconds

So, 400 feet in 52.4 seconds

So, in 1 second =

                        =

So, unit rate =7.6 ft/sec

Hence 400 feet in 52.4 seconds as unit rate is 7.6 ft/sec

if you was gonna solve for a, a is a   < -12

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
