A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answers
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet

Step-by-step explanation:
Angles 2, 3 and 4 are taking up 180 degrees because it is 1/2 of a circle. That means angles 1 and 5 are also taking up 180 degrees because both the angles add up to a straight line
Answer:
I hope you will understand my explanation
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: 60° and 120° are supplementary angles.

Michael has a points card for a movie theater.
He receives 35 reward points just for signing up.
He earns 2.5 points for each visit to the movie theater.
He needs 70 points for a free movie ticket.
Write and solve an equation that can be used to determine v, the number of visits Michael must make to earn a free movie ticket.
Answers
Let the number of visits equal x.
Multiply the number of points by the points per visit.
2.5x
Add that to the points he got for signing up:
2.5x + 35
This needs to equal the total points needed:
2.5x + 35 = 70
Solve for x:
Subtract 35 from both sides:
2.5x = 35
Divide both sides by 2.5:
X = 14
He needs 14 visits

Step-by-step explanation:
Average speed is given by [tex]S=\frac{d}{t}[/tex], where [tex]d[/tex] is distance and [tex]t[/tex] is elapsed time.
Since we want the average speed of the entire trip, we need to total distance of the entire trip and the total time it takes for the entire trip.
What we know:
The trip took 2 hours (2:30 PM to 4:30 PM)The bus travelled [tex]22.5+42.8+42.7=108[/tex] kilometersSubstituting known values, we get:
