Answer:
x = 2
Step-by-step explanation:
Using the scale factor, we have ...
x/8 = 0.25/1
x = 8(0.25) . . . . multiply by 8
x = 2

<em>Additional comment</em>
I like to write proportions with the variable in the numerator. That way they are easily solved by a single multiplication. The trick is to get corresponding parts in the same positions. Here, the fractions are written ...
B/A = smaller part / larger part = x/8 = 0.25/1
4+4x=20
-4. -4
4x=16
X=4 (hope this helps)
TanB has a ratio of 8/15 because it is opposite over adjacent.
The answer is C
Since we don’t know how much supplies cost in general it would be better to first find out how much the painter charges for the 5 hours
15.28 x 5 = 76.45$
Now that we know that we just need to solve for the difference. So subtract the total cost to the amount he charged for 5 hours of work
157.18 - 76.45 = 80.73
Answer:
125.6 sq ft.
Step-by-step explanation:
To find the Surface Area of the cylinder, we will need to solve for the area of both bases and the rectangle around the cylinder. We can do this by:
------------------------------
Area of bases: (
)
Since we have two bases, we can simply multiply by 2, giving us:
12.56×2= 25.12
-------------------------------
Area of the rectangle: (
)
12.56×8= 100.48
Add these two together, giving us:
100.48+25.12= 125.6 sq ft.
