Answer:
True
Step-by-step explanation:
It is true because the graph of 
passes through the point 
x = 16
y = 4
Substitute
4 = 16 - 12
4 = 4
Therefore, the answer is true.
Answer:
The ratios are both identical (3/5 and 3/5).
Step-by-step explanation:
sin x° is equivalent to O/H, or the opposite/hypotenuse sides of the triangle. Therefore:
sin x° = 3/5.
cos y° is equivalent to A/H, or the adjacent/hypotenuse sides of the triangle.
cos y° = 3/5.
The ratios are identical.
Total distance covered is equal to ~
- Number of revolutions × circumference
Hence distance covered = 2200 m = 2.2 km

Answer:
A) (3 cm x 4 cm ÷ 2) x 3 cm
Step-by-step explanation:
The volume is the product of the area of the triangular bases and the distance between them.
Each right triangular base has a width of 3 cm and a height of 4 cm. Its area will be given by ...
A = (1/2)bh
A = (1/2)(3 cm)(4 cm) = (3 cm × 4 cm) ÷ 2
__
The distance between the triangular bases is marked at the left side of the diagram as 3 cm. So, the volume is ...
V = Bh
V = (3 cm × 4 cm ÷ 2) × 3 cm . . . . . matches choice A
There aren't any more steps. The answer starts by saying how the volume is computed. Then it shows how to find the numbers that go into that computation. Finally, it puts all that together in the form that is required to match an answer choice.
It might also be useful for you to draw the net to scale on a piece of paper, cut it out, and fold it along the lines to actually make a triangular prism. A little hands-on is always helpful in math. It only takes 5 or 10 minutes and can give you great insight into both prisms and nets.
The answers are A and B . The positive ones can’t be right because it you keep adding and multiplying positives then your number increases
