Answer:
<h3>The surface area of the prism is A prism=204m2</h3>
Step-by-step explanation:
Area is the space that is contained in a two-dimensional figure.
Surface area is the total area of all of the sides and faces of a three-dimensional figure.
To find the surface area, the area of each face is calculated and then add these areas together.
To find the area of a rectangle, multiply the length by the width .
From the graph the length of the rectangle is 10 m and the width is 8 m. Therefore, the area of the bottom face is
From the graph the length of the rectangle is 10 m and the width is 5 m. Therefore, the area of one of the rectangular side faces is
To find the area of a triangle use the following formula where b is the base and h is the height.
From the graph the base of the triangle is 8 m and the height is 3 m. Therefore, the area of one of the triangular faces is
The surface area of the prism is the sum of the area of the bottom face, the area of the two rectangular side faces, and the area of the two triangular faces

The answer is 22.6 so the quotient would be between 22.0 and 23.0, hope this helps.
Two workers finished a job in 7.5 days.
How long would it take each worker to do the job by himself if one of the workers needs 8 more days to finish the job than the other worker?
let t = time required by one worker to complete the job alone
then
(t+8) = time required by the other worker (shirker)
let the completed job = 1
A typical shared work equation
7.5%2Ft + 7.5%2F%28%28t%2B8%29%29 = 1
multiply by t(t+8), cancel the denominators, and you have
7.5(t+8) + 7.5t = t(t+8)
7.5t + 60 + 7.5t = t^2 + 8t
15t + 60 = t^2 + 8t
form a quadratic equation on the right
0 = t^2 + 8t - 15t - 60
t^2 - 7t - 60 = 0
Factor easily to
(t-12) (t+5) = 0
the positive solution is all we want here
t = 12 days, the first guy working alone
then
the shirker would struggle thru the job in 20 days.
The speed of the driver is 200km/hr.
<h3>How to calculate the speed?</h3>
The information is incomplete and an overview will be given since the complete information wasn't found online.
It should be noted that speed is calculated as:
= Distance / Time
Let distance = 2000km
Let time = 10 hours.
Speed = Distance/Time
Speed = 2000/10
Speed = 200km/hr
