Step-by-step explanation:
32 ÷ 4 + (
= 8 + (1*8) - 2
= 8 + 8 - 2
= 16 - 2
= 14
Answer:
Speed = 0.0003miles/hr
Step-by-step explanation:
Speed of object = 1 mile/hour
For every meter it travels, its acceleration increases by 1 mile/hour
∆Distance = increase in distance
∆speed = 1 meter
The speed and the distance are constant
Speed = distance/time
Time = distance/speed = 1meter/(1 miles/hr)
Convert meter to miles
1609.34 meters = 1mile
1meter = (1meter × 1mile)/(1609.34 meters)
1 meter = (1/1609.34)miles
Time = distance/speed = (1/1609.34)miles/(1 miles/hr)
Time = (1/1609.34)hr
We are to determine the speed the object would be travelling in half of an hour?
In 1hr, it travels (1/1609.34)miles
In ½hr, it travels = (1/1609.34)(½)hr
Speed = 0.0003miles/hr
It will be travelling 0.0003miles/hr in half of an hour
Answer: There are 140 adults and 40 children.
Step-by-step explanation:
Let 2x = Number of children
7x = Number of adults.
As there are 100 more adults than children.
That means, 
Number of children = 2 (20)=40
Number of adults = 7(20) = 140
Hence, there are 140 adults and 40 children.
Oma made a mistake in step B, because she should have divided both sides by b instead of just moving it to the other side. The real next step would look like:
(2A)/b=h
