Answer:
Perimeter: 26 units
Area: 24 units²
Step-by-step explanation:
12 + 9 + 5 = 26
A = 1/2BH
A = 1/2 12(4)
A = 1/2 48
A = 24
450 >_ 750 - 70x
450 >_ 750 - 70x
(subtract 750 on both sides)
-300 >_ -70x
(divide by -70 to get x alone, then flip the inequality sign)
4 2/7 <_ x
(round up to 5, you can’t have 2/7 of a person)
at least 5 people have to get off
hope this helped!
Answer:
3.79 miles per hour to the nearest hundredth.
Step-by-step explanation:
There are 3600 seconds in 1 hour.
50 feet in 9 seconds = 50/9 feet per second.
= (50/9) * 3600 feet per hour
= (50/9) * 3600 / 5280 miles per hour.
= 50 * 400 / 5280
= 3.79 miles / hour.
Answer:

1+9y=10y
sorry if I got some wrong I tried my best.
