. A building in the shape of a rectangular prism needs to be painted. Some facts about the building are shown below. The buildin

g has a width of 50 feet, a length of 80 feet, and a height of 120 feet. • There are 60 windows on each lateral face of the building. • Each window is a square measuring 5 feet on a side. Using this information, which expression represents the total lateral surface area, in square feet, that needs to be painted? o (2) (120) (80) + (2) (120) (50) – (60) (52) o (2) (120) (80) + (2) (120) (50) – (4) (60) (52) o (2) (50) (80) + (2) (120) (80) + (2) (120) (50) – (60) (52) o (2) (50) (80) + (2) (120) (80) + (2) (120) (50) – (4) (60) (52) - Previous​

Answer:

(2)(120)(80) + (2)(120)(50) - (4)(60)(5²)

Step-by-step explanation:

The lateral faces of the building are the 4 sides of the building consisting:

2 rectangles of 120 ft by 80 ft

Area of the two rectangular faces = (2)(120)(80)

And

2 rectangles of 120 ft by 50 ft

Area of the two rectangular faces = (2)(120)(50)

✔️Total lateral surface area of the building = (2)(120)(80) + (2)(120)(50)

Note: we are asked to find the expression that represents the total surface area that needs to be painted given that there are 60 windows on each lateral face of the building of the shape of a square with side lengths of 5 ft.

Therefore, the total lateral surface area of the building that will be painted = total lateral surface of the building - total area covered by the 60 windows on each face of the building

Surface area covered by 60 windows in the 4 lateral face of the building = (4)(60)(5²)

✅total lateral surface area of the building that will be painted = (2)(120)(80) + (2)(120)(50) - (4)(60)(5²)

If B is the midpoint of AC and AB = 4x + 14 and BC = x + 20, determine how long AC is.
Serhud [2]

Answer:

44 units

Step-by-step explanation:

Since B is the mid-point of AC

AB=BC

or,4x+14=x+20

or, 4x-x=20-14

or 3x=6

or,x=6/3=2

AC=AB+BC

= 4x+14+x+20

= 4(2) + 14 +2 +20

= 8+14+22

=44 units

For example, if it takes 15 hours to travel 900 miles. How many miles will you travel in one hour?
dalvyx [7]

Answer:

60 miles

Step-by-step explanation:

If it takes 15 hours to travel 900 miles then it gives you the fraction 15/900 where the numerator(top number) is 15 and denominator(bottom number) is 900.

Then to simplify it: since 15 is a common factor of itself(15) and 900, 15/15 = 1(1 hour) and 900/15 = 60(60 miles).
