Answer: 23.2 miles per hour

Step-by-step explanation:

He ran 100 meters in 9.63 seconds.

First convert the number of meters he ran to miles:

= 100 * 3.28

= 328 feet

= 328/5,280

= 0.062121212 miles

Convert the seconds to hours:

= 9.63 / 60

= ‭0.1605‬ minutes

= ‭0.1605‬/60

= ‭0.002675‬ hours

Speed in miles per hour is:

=  0.062121212 / ‭0.002675

= 23.22

= 23.2 miles per hour

V125BC [204]

Answer: please mark me brainliest

In 1 hour, the first train will have traveled 60 miles.

Let t be the time before the first train catches up to the second. Then:

60t+60=80t

20t=60

t=3 hours

Since the 2nd train leaves at 1:00, and travels 3 hours before catching up, he will catch the 1st train at 4:00 p.m. …………………

Edgar purchased a home for $182,100 to home appreciates about 3.5% each year what is the value of the home after 12 years
olasank [31]

Answer:

the value of the home after 12 years =$275,165.60

Step-by-step explanation:

To find value of appreciation after 12 years

We apply exponential growth formula

y=a(1+r)^x

Where a represents the initial amount (purchased amount)

a= 182,100

r = rate of interest ( appreciation percentage) = 3.5% = 0.035

x  represents the time period= 12 years

Plug in all the values

y=a(1+r)^x

y=182100(1+0.035)^12

y= 275165.6025027724  

y=$275165.60

A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that
Sphinxa [80]

Answer:

150c + 13,700 < 23,000

Step-by-step explanation:

Greatest weight that can be loaded into the container = 23,000 kilograms

Weight of each crate = 150 kilogram

Weight of other shipment = 13,700 kilograms

c = total number of 150-kilogram crates that can be loaded

This can be represented by the inequality:

150c + 13,700 < 23,000

That is, Weight of each crate multiplied by total number of 150-kilogram crates that can be loaded Plus Weight of other shipment less than greatest weight that can be loaded into the container
