The area of the parrallelogam is 5*9=45m. The area of the triangle is 1/2*8*9=36m. Added them together, 36+45=81m^2
Answer:
cost per minute is 0.04
Step-by-step explanation:
Unit rates defined as the rates are expressed as a quantity of 1 such as 2 feet per second or 5 miles per hour they are called unit rates.
Given: Costs = $ 30 a month
In a month of may she used cellphone 12.5 hours.
First convert 12.5 hours in minute.
Use conversion: 1 hour = 60 minutes
then, 12.5 hours =
to find the cost per minute.
by definition;
unit rate(cost per minute ) = cost per minute.
therefore, her cost per minute is 0.04
Solving for X:
1) y=-8x+6.5 y=-4x+11
2) -8x+6.5=-4x+11
3) -8x=-4x+11-6.5 (Subtract 6.5 from both sides)
4) -8x+4x=11-6.5 (Add 4x to both sides)
5)-4x=4.5
5)x=-1.125
Solving for Y:
y=-8(-1.125)+6.5
y=9+6.5
y=15.5
y=-4(-1.125)+11
y=4.5+11
y=15.5
x=-1.125
y=15.5
or
(-1.125,15.5)
