Below are the choices that can be found from other sources:
A. 42
<span>B. 45 </span>
<span>C. 47 </span>
<span>D. 48 </span>
<span>E. 49
</span>
The answer is C or 47. The object’s resultant angle of motion with the +x-axis after the collision is 47. The reason for that is f<span>rom object A’s x-momentum is 5.7 × 104 kilogram meters/second and its y-momentum is 6.2 × 104 kilogram meters/second, we know that tan of the angle from the x-axis is 6.2 / 5.7 = 1.09 and acrtan 1.09 = 47.4</span>
The way I picture this thing, it's made of three rectangles
that are joined together.
-- One rectangle is 3 x 6 meters.
-- One rectangle is 3 x 8 meters.
-- One rectangle is 3 x 10 meters.
-- Their 3-meter edges are all taped together to make a 'tube'.
-- It's 3 meters long, and it has 3 sides.
-- When you look at the ends of the tube, they're both
right triangles with sides of 6, 8, and 10 meters.
-- The area of each side = 1/2 (base x height)
= 1/2(6m x 8m) = 24 square meters.
2 ends = 48 square meters.
-- The lateral surface area is the area of the three rectangles
that make the 'tube'.
-- Area of the 6 x 3 rectangle = 18 square meters
-- Area of the 8 x 3 rectangle = 24 square meters
-- Area of the 10 x 3 rectangle = 30 square meters
-- Total lateral area = (18 + 24 + 30) = 72 square meters.
-- When you add the ends to it, you get
(72 + 48) = 120 square meters
for the total area.

Answer: 7/8
Step-by-step explanation:
To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .
So if we multiply both numerator and denominator by 2, we will get
