Answer:
18 square units
Step-by-step explanation:
The distance from -2 to 7 is 9, which is the base of the rectangle. The distance from -2 to -4 is 2, which is the height of the rectangle. The formula for area of a rectangle is A=bh. 9*2=18. 18 square units is your answer.
Answer:
Each project has 2.500 man-hours
Step-by-step explanation:
Available man hours: 5000
For two projects Costs $
X: project A 10
Y: project B 12
Approach:
X + Y = 5000 => X = 5000 - Y
10 * X + 12 * Y = 55000
replacing:
10 * (5000 - Y) + 12 * Y = 55000
50000 - 10 * Y + 12 * Y = 55000
2 * Y = 55000 - 50000
Y = 5000/2
Y = 2500
For X:
X = 5000 - 2500
X = 2500
The number of hours available for each project are:
Projects Man hours
X: project A 2500
Y: project B 2500
Supplementary means it adds up to 180 degrees.
So if one side is 31 degrees, you would need to subtract that from 180 to find the other side.
-----------------------
180 - 31 = 149
-----------------------
The other angle would be 149 degrees.
A unit rate will always end up having one as its denominator so divide 305 by 5 which is 61 rotations/1 minute.
