Answer:
$ 256
Step-by-step explanation:
square footage of door = 8 x 4 = 32 ft^2
32 ft^2 * 8 dollar /ft^2 = $ 256
Answer:
26.8°
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side of the triangle in which the angle is formed to the hypotenuses side of the triangle. The cosine of the angle gives the ratio of these sides. However, the arc cosine of the ratio gives the angle measured in degrees.
If cos B = 0.8926
then arc cosine 0.8926 which may be expressed as cos-1 0.8926 will give the value of B.
B = cos-1 0.8926
= 26.8°
Answer:
3
Step-by-step explanation:
List all possible factors of each number. The GCF will be the largest number they both share
Factors of 18: 1, 2, 3, 6, 18
Factors of 15: 1, 3, 5, 15
The largest number they both share is 3, so that is the GCF
The function g is defined by:
g(x) = (4 + x) / (5 + 3x) ...(1)
Now, we need to find g(5n); that is, we make: x = 5n
Replacing this into equation (1):
g(5n) = (4 + 5n) / (5 + 3*(5n)) = (4 + 5n) / (5 + 15n)
So, the final answer is:
g(5n) = (4 + 5n) / (5 + 15n)
