Answer:
B. 10.71 cents
Step-by-step explanation:
Benito's other expenses total ...
$809 +170 +57 = $1036
so his gas expense is ...
$1822 -1036 = $786
Then the per-mile cost is ...
$786/(7340 mi) ≈ $0.10708/mi
Benito's gas cost averaged 10.71¢ per mile.
Answer:
$135.01
Step-by-step explanation:
A mark up of 100% means that the price was doubled.
58.7*2=117.4
To add sales tax to a price (p) you need to do p+(sales tax * p)
117.4+.15(117.4)
135.01
Answer:
(-2,6)
Step-by-step explanation:
Answer:
45 degrees
Step-by-step explanation:
the 2 angles are supplementary (add up to 180 degrees)
180-135=45
The surface area of the composite figure is 144 square cm after calculating separately.
<h3>What is a triangular prism?</h3>
When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is the name given to this novel 3D object.
We have a composite figure made up of a triangular prism and a cuboid
First we calculate the surface area of the triangular prism:
= 2(area of one triangle) + area of three rectangles
= 2[(1/2)6×4] + 3×5 + 3×5
= 24 + 15 + 15
= 54 square cm
Surface area of rectangle(with three faces) = 2(4×3 + 4×6) + 3×6
= 2(12 + 24) + 18
= 72 + 18 = 90 square cm
Total surface area of figure = 54+ 90 = 144 square cm
Thus, the surface area of the composite figure is 144 square cm after calculating separately.
