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?
55ft²
Answer:
Solution given:
the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2
=base area *2 laternal faces area
=25+2*15=25+30=55ft²

Answer:
[tex]54\:\mathrm{km/h}[/tex]
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:
[tex]S_{avg}=\frac{108\:\mathrm{km}}{2\:\mathrm{h}}=\boxed{54\:\mathrm{km/h}}[/tex]

Answer:
b) 42°
c) 138°
Step-by-step explanation:
Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.

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.
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
The Smith family have decided to build a uniform walkway that is 3 ft wide using Travertine pavers around their rectangular swimming pool which measures 16 ft by 24 ft.
What is the area of the walkway? - 384 ft sq.
The paver selected by the family measures 6 in by 12 in. How many pavers are needed to cover the walkway?
Answer:
not sure
Step-by-step explanation:
6*12=72, 72in to feet is 6ft
384/6=64ft
Answer:
384 divided by 72 (6 times 12) = 5.33 i think
What is the circumference of each circle? Use 3.14 for PIE. Round to the nearest tenth if necessary.
which angles are supplementary to each other ? select all that apply
Answer:
∠1 and ∠5
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.

HELP ME ASAP!!! Tristan is stacking building blocks to make a tower. He takes a break when the tower is 5 2/5 feet tall, which is 1/3 of the height of the tower he wants to build. How tall is the tower when finished? Check all that apply
A. 1/3 x ? = 5 2/5
B. 1/3 ÷ 5 2/5 = ?
C. 5 2/5 x ? = 1/3
D. 5 2/5 x 1/3 = ?
E. 5 2/5 x 3/1 = ?
F. 5 2/5 ÷ 1/3= ?
Honestly, I'm not sure how to answer this, but I think this can help you.
Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.

Answer:
B) [tex]x=\sqrt{90}[/tex]
Step-by-step explanation:
Pythagorean thm formula:
a² + b² = c²
Given:
a = 9
b = 3
c = x
Work:
a² + b² = c²
9² + 3² = x²
81 + 9 = x²
90 = x²
[tex]\sqrt{x^2} =\sqrt{90} \\x=\sqrt{90}[/tex]
A cylinder is sliced perpendicular to its circular base. What shape will the cross section be?
Answer:
RECTANGLE

Step-by-step explanation:
If its sliced perpendicular from its circle base, that means its cutting vertically from it since perpendicular lines form a 90 degree angle.
Crayola Classic markers come in packages of eight. Crayola Tropical markers come in packages of ten. Sheldon wants the same number of Classic and Tropical markers. What is the fewest number of packages he could buy of each type of marker? Show proof of your answer.

Crayola Classic: 5 Packs; Crayola Tropical: 4 Packs
Step-by-step explanation:
Keep multiplying by both until you get a number equal to eachother
1. 8 x 2 = 16, 10 x 2 = 20
2. 8 x 3 = 24, 10 x 3 = 30
You may notice that the numbers are getting farther apart. This is normal because the boxes are not equal and are getting multiplied further. That means that your answer will have different factors in both the equations.
3. 8 x 4 = 32, 10 x 4 = 40
4. 8 x 5 = 40
Both of those equations (in bold) have the same answer and he wanted the same crayons from both. So, the answer is:
10 x 4 = 40
8 x 5 = 40
(how much packs of each you need to get the same amount)
Hope this helps :)
