The formula for b from the given area is equal to (2A / h).
As given in the question,
Formula to find area of a triangle is equal to A = (1/2) b h
b represents the base of the triangle
h represents the height of the triangle
A = (1/2) b h
Multiply both the side by 2 in area formula
2A = b h
Divide both the side by h
b = (2A) / h
Therefore, the formula for b from the given area is equal to (2A / h).
The complete question is:
The formula A = (1/2)b h represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b.

Answer:
option A, option C, option D
Step-by-step explanation:
a) 1 ÷ m/6
can be written as
÷ 
b) sides in (m/6) will change if both has to multiply
c) 1 ÷ m/6
can be written as
1 * 6/m
1(
) and wont make change to answer. so matches with the question.
d)
1 ÷ m/6
1 * 6/m
1 * 6 * 
6 *
6 ÷ m ..therefore true
e)
1 ÷ m/6
1 * 6/m
6/m ....does not match or can be converted to the following so wrong
- Therefore A, C, D are correct and B and E is wrong.
Answer:
It would take 50 minutes
Step-by-step explanation:
<u>Distance, velocity and time</u>
The speed is the rate at which the distance changes with respect to time. If x is the distance, t is the time, the speed v can be obtained by
We know the trip takes 40 minutes when traveling at 50 miles/hour. The distance can be determined by isolating x in the above equation
The given time is expressed in minutes, we need to convert it to hours. 40 minutes is 
. The distance is
If the speed was 40 miles/hour, the same distance would be covered in t hours, taken from the above equation as
Answer:

Both computers will do the job in 5 hours and 14 minutes.
Since a computer can process the payroll for Hometel in 10 hours, while an older back up computer needs 11 hours to process payroll, to determine how long would the job take if the two computers are both used to do the job, the following calculation should be performed:
- X / 10 + X / 11 = 1
- 10X + 11X = 110
- 21X = 110
- X = 110/21
- X = 5.238
- 100 = 60
- 0.238 = X
- 0.238 x 60/100 = X
- 0.14 = X
Therefore, both computers will do the job in 5 hours and 14 minutes.
