Answer:
10 gallons of paint
Step-by-step explanation:
First, find the surface area of the monument.
From inspection, this is made up of 4 congruent rectangles and 4 congruent triangles.
Area of a rectangle = width x length
Therefore, area of one rectangle of the monument:
13 x 40 = 520 ft²
Area of triangle = 1/2 x base x height
Therefore, area of one triangle of the monument:
1/2 x 13 x 11 = 71.5 ft²
Therefore, total surface area of the monument
= 4 x SA of rectangle + 4 x SA of triangle
= 4 x 520 + 4 x 71.5
= 2080 + 286
= 2366 ft²
We are told that one gallon of paint can cover 239 ft², and that paint can only be bought by the gallon.
Divide the total surface area of the monument by the area one gallon of paint can cover to calculate how many cans of paint are needed.
2366 ÷ 239 = 9.89958159...
Therefore, 10 gallons of paint must be bought (since we need to round up as paint can only be bought by the gallon).
Answer: Yes
Step-by-step explanation:
Using the vertical line test, we draw a bunch of lines that go up and down. We can see there is no point where a vertical line has 2 intersections.
Answer:
Mykel can make 2.79 x 10³² different combinations
Step-by-step explanation:
We can solve this problem using combination
The formula for combination is ⁿCₐ = 
where n = total number of choices available
a = number of items being chosen
The total movies Mykel wants is 99.
Taking out the sure 66 drama movies,
Mykel is left with 99 - 66 choices = 33 choices.
The total number of choices he is left with is 66 foreign + 33 children + 44 documentaries = 143 movies
Hence, our n = 143 movies
and a = 33 choices
Hence we do, ¹⁴⁴C₃₃ = 
= 
2.79 x 10³² combinations
∴ Mykel can make 2.79 x 10³² different combinations.
