Step-by-step explanation:
The area of triangle is
=21×height×base=21×3×4=3×2=6 cm2
perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
Answer:
300+4x < (9+5)*x
Step-by-step explanation:
x is number of times Robert goes to the gym
The conversions factors needed are 1 mile= 5280 feet and 1 hour = 3600 seconds, speed in ft/s = 14.67 ft/s
<u>Solution:
</u>
Given, A runner is running 10 miles per hour.
We have to find what conversion factors should be used to convert 10 mi/hr to ft/s?
Now, speed of runner = 10 miles per hour.
But we need the units to be in ft / s.
Then, conversion factors are miles to feet and hours to seconds.
Now, miles to feet ⇒ 1 mile = 5280 feet.
Now, hours to seconds ⇒ 1 hour = 3600 seconds

Hence, the conversions needed are 1 mile = 5280 feet and 1 hour = 3600 seconds, speed in ft/s = 14.67 ft/s
