<span>If so, 87 - 66 = 21 / (12-5) = 3 degrees Fahrenheit per hour.</span>
Answer:
Step-by-step explanation:
L = 2 + sqrt(2)
W = 4 - 2sqr(2)
Area = L * W
Area = (2 + sqrt(2) )* (4 - 2sqrt(2) )
Use Foil
- F: 2*4 = 8
- O: 2*(-2sqrt(2) = - 4sqrt(2)
- I: 4*sqrt(2)
- L: sqrt(2)*(-2sqrt(2) = - 2*2= - 4
Result
Area = 8 - 4 - 4sqrt(2) + 4sqrt(2)
Area = 4
Answer:
Pies=$0.85
Donuts= $1.20
Step-by-step explanation:
In the equation let p stand for the number of pies and d stand for the number of donuts.
To solve this set up 2 equations, one representing bill and the other representing Mary Ann.
- Bill's equation is 5p+7d=$12.65.
- Mary Ann's equation is 6p+6d=$12.30
Then solve using a system of equations. Systems of equations can be solved using elimination or substitution. I will use substitution. Solve bill's equation for p. This gives you
. Then, you can substitute that into Mary Ann's equation. This looks like
. Solve for d. Once you solve d=1.20. Finally, substitute 1.20 back into either Bill's or Mary Ann's for d and solve for p. No matter which equation you use p=0.85.
