Answer:
Roger works 30 hours and his brother works 50 hours
Step-by-step explanation:
Let
x ---->the number of hours Roger works in a month
y ---->the number of hours his brother works in a month
step 1
Find out how much they earn per hour
5,400-3,240=$2,160 -----> amount earned by 20 hours of work
$2,160/20=$108 per hour
step 2
Find out how many hours each brother works in a month
Roger
108*x=3,240
x=3,240/108=30 hours
His brother
y=x+20
y=30+20=50 hours
The hypotenuse will be bigger than either of the legs so we can rule out B and C. It will be pretty close to the diagonal of a 3×3 square so 3√2 = 3 × 1.4 = 4.2. Our preliminary guess is A.

The shape of the cross section is a triangle. Therefore, the answer is the second option: Triangle.
A rectangular pyramid is a pyramid that has a rectangle as its base. Therefore, its base has four sides. The rectangular pyramid also has four triangles that coming together in its apex. So, if the rectangular pyramid is<span> sliced so the cross section is perpendicular to its base and passes through its vertex, the cross section obtained is a triangle.</span>
