Answer:
32−4(4)=−30
Step-by-step explanation:
Combine like terms 6+26+40=4(4)+1032+40=4(4)+102
Subtract 404040
from both sides of the equation 3
Simplify 4
Subtract 4(4)4(4x)4(4x)
from both sides of the equation 5
Simplify
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
Answer: 7.62
Step-by-step explanation:
Answer: $443.32
Step-by-step explanation:
Hi, to answer this question we have to calculate perimeter of a semicircle:
P = π (d/2) + d
Where d is the diameter
Replacing with the values given:
P = 3.14 (23/2) + 23 = 59.11 feet
Since each linear foot cost $7.50, we have to multiply that cost by the perimeter.
59.11 x 7.50 = $443.32
Feel free to ask for more if needed or if you did not understand something.
4 divided by 726 would be about 0.005509
