What is the surface area of this
square pyramid?
Answers
Answer:
The surface area of a square pyramid is the sum of the areas of all its 4 triangular side faces with the base area of the square pyramid. If a, h, and l are the base length, the height of the pyramid, and slant height respectively, then the surface area of the square pyramid = a2+ 2al (or) a2+2a √a24+h2 a 2 4 + h 2 .

Answers
Answer:
To find the average price of all 4 pies, we have to know the price of all 4 pies. You have only given the price of 3 of the pies, so there is no way to figure the average. The best you can do in this case is say that the peach pie costs (6 + 7 + 11 + X) / 4 dollars, where X is the cost of the peach pie.
I think you meant to say that the peach pie cost the average of the prices of the other three pies. In which case, it costs (6 + 11 + 7) / 3, or $8.00.

3. Tickets to a show cost $5.50 for adults and 54.25 for students. A family is purchasing2
adult tickets and 3 student tickets.
Answers
.
Step-by-step explanation:The cost of an adult ticket to the show is $5.5
The cost of a student ticket to the show is $4.25
A family is purchasing 2 adult tickets and 3 student tickets. This means that the total cost of 2 adult tickets would be
2 × 5.5 = $11
It also means that the total cost of 3 student tickets would be
3 × 4.25 = $12.75
The total cost of 2 adult tickets and 3 student tickets would be
11 + 12.75 = $23.75
If the family pays $25, the exact amount of change they should receive is
25 - 23.75 = $1.25

Step-by-step explanation:
The 3rd interior angle of the triangle can be written as
[tex]\angle{3} = 180 - 45 - x = 135 - x[/tex]
The angle above is supplementary to the angle (2x - 2), therefore
[tex](135 - x) + (2x - 2) = 180 \Rightarrow 133 + x = 180[/tex]
Solving for x, we get

A question on a test provides this graph and asks students to find the speed at which the car travels. Anna incorrectly says that the speed of the car is 1/64 mile per hour.
What is the speed of the car?
What error might Anna have made?
Answers
Answer:
A question on a test provides this graph
You, however, did not provide the graph.
Please repost the question along with the graph.
The speed is the rate of change of distance with respect to time thus the speed according to the graph will be 60 miles per hour so Anna interchanged distance and time by mistake.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given graph.
Speed = distance traveled / time taken
Speed = 60 / 1 miles per hour
But Anna says 1/60 this means Anna took time taken / distance traveled instant of distance traveled / time taken.
Hence "The speed is the rate of change of distance with respect to time thus the speed according to the graph will be 60 miles per hour so Anna interchanged distance and time by mistake".

a. The graph of y = 2x represents a transformation of the parent function, y = x, which makes the graph twice as steep.
b. The graph of y = 2x represents a transformation of the parent function, y = x, which makes the graph half as steep.

At the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below -
P(h) = P[tex]e^{-0.000122h}[/tex]
where {P} is the air pressure at the surface of the Earth, and his the height above the surface of the Earth, measured in meters.
For 50% of the air pressure at the surface of the Earth, we can write -
50P/100 = P[tex]e^{-0.000122h}[/tex]
1P/2 = P[tex]e^{-0.000122h}[/tex]
1/2 = [tex]e^{-0.000122h}[/tex]
- 0.000122h = log(1/2) = - 0.301
h = - 0.301/- 0.000122
h = 2467.2 meters
Therefore, at the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.
