What is the surface area of the square pyramid?
A net has a square base with side lengths of 2, and 4 triangles with heights of 3.
square units:
9514 1404 393
Answer:
16 square units
Step-by-step explanation:
The area of the square base is ...
A = s²
A = 2² = 4
The area of each triangle is ...
A = (1/2)bh
A = (1/2)(2)(3) = 3
So, the area of the base and 4 triangles is ...
total area = 4 + 4(3) = 16 . . . square units

There is a bell at the top of a tower that is 45m high. The bell weighs 190 kg. How much potential energy does the bell have?
Answer:
83.79 kJ
Step-by-step explanation:
The potential energy is the product of weight and height, where weight is in newtons.
PE = Mgh = (190 kg)(9.8 m/s^2)(45 m) = 83,790 J
3. Which line is horizontal?
A. y = 2
B. y = 2x
C. y = -2x
D. y = x
Answer: y = 2
Explanation: When the equation of any line reads y = a number, its graph will always be a horizontal line.
So, y = 2 would be a horizontal or flat line.

The partial pressure of carbon dioxide in a mixture is 0.31 atm.
If the mole fraction of the carbon dioxide is 0.46, what is the
total pressure of the mixture?
Answer:
[tex] P_{Co2}= X_{Co2} P_{tot}[/tex]
Where [tex] P_{tot}[/tex] represent the total pressure and [tex]X_{Co2}[/tex] the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:
[tex] P_{tot}= \frac{P_{Co2}}{X_{Co2}}[/tex]
And replacing we got:
[tex] P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm[/tex]
Step-by-step explanation:
For this case the partial presure of carbon dioxide is given by:
[tex] P_{Co2}= X_{Co2} P_{tot}[/tex]
Where [tex] P_{tot}[/tex] represent the total pressure and [tex]x_{Co2}[/tex] the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:
[tex] P_{tot}= \frac{P_{Co2}}{X_{Co2}}[/tex]
And replacing we got:
[tex] P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm[/tex]
lisa will choose between two restaurants to purchase pizzas for her party. the first restaurant charges a fee of $5 for the entire purchase and $16 per pizza. The second restaurant has no delivery fee and charges $17 per pizza. Please help and hurry
Every time, this second restaurant is less expensive; therefore, Lisa should decide to get pizzas for her group from the second restaurant.
What is the accounting definition of a purchase?All items and services purchased for resale of consumption throughout the production process are included in spending on goods and services, excluding capital goods whose consumption is recorded as consumption for fixed capital.
We have For the first restaurant
the total cost per pizza is $16 + $5 = $21.
For the second restaurant
the total cost per pizza is $17.
If Lisa purchases x pizzas,
the total cost from the first restaurant will be $21x + $5 = $21x + $5.
The total cost from the second restaurant will be $17x.
If x = 1, the first restaurant will cost $26 and the second restaurant will cost $17, so the second restaurant is cheaper.
If x = 2,
the first restaurant will cost $47 and the second restaurant will cost $34, so the second restaurant is cheaper.
If x = 3, the first restaurant will cost $68 and the second restaurant will cost $51, so the second restaurant is cheaper.
So, in every case, the second restaurant is cheaper, and Lisa should choose the second restaurant to purchase pizzas for her party.

on green 18 times. What would you estimate
as the probability of the spinner not landing

Step-by-step explanation:
Given:
A spinner is divided into 4 sections using the colours: red, orange, yellow, and green. After 50 trials, the spinner landed on red 10 times, on orange 16 times, on yellow 6 times, and on green 18 times.
To find: probability of the spinner not landing on yellow
Solution:
Probability is the chance of occurrence of some event.
Total number of outcomes = 50
Number of favourable outcomes = 50 - 6 = 44
Probability of the spinner not landing on yellow = Number of favourable outcomes / Total number of outcomes = [tex]\frac{44}{50}=\frac{22}{25}=0.88[/tex]

of c units. Complete each equation to show three relations among a, b, and c.
a. c² =
b. a^2=
c. 6² =
Answer:
[tex]\text{a. }c^{2} = a^{2} + b^{2}[/tex]
[tex]\text{b. }a^{2} = c^{2} - b^{2}[/tex]
[tex]\text{c. }b^{2} = c^{2} - a^{2}[/tex]
Step-by-step explanation:
Please refer to the attached figure in which [tex]\triangle ABC[/tex] is shown with sides a, b and c.
It is given a right angled triangle with sides a, b and c.
And c is the longest side.
So, it is clear that 'c' is the hypotenuse of the triangle because hypotenuse is the longest side of a right angled triangle.
No condition is given about the base and height.
So, let 'a' be the height and 'b' be the base of triangle as shown in the attached figure in the answer area.
We know that, pythagoras' theorem holds true in every right angled triangle.
According to pythagoras' theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}\\\Rightarrow c^{2} = a^{2} + b^{2} .......... (1)[/tex]
So, Answer [tex]\text{a. }c^{2} = a^{2} + b^{2}[/tex]
Using equation(1):
Answer [tex]\text{b. }a^{2} = c^{2} - b^{2}[/tex]
Also,
Answer [tex]\text{c. }b^{2} = c^{2} - a^{2}[/tex]

A support wire extends from the top of a 225 feet radio tower to the ground and makes an angle of 64° with the ground. How long does the wire need to be to reach from the top of the tower to the ground?
Answer:
250.34 feet
Step-by-step explanation:
Find attached to this answer and appropriate diagram.
From this question, we can see that this is a trigonometric function
The height of the radio tower = 225 feet = Opposite side
θ = Angle 64°
In the question we are told to find the length of the wire needed to reach from the top of the tower to the ground.
From the attached diagram, we can see that that is equivalent to finding the hypotenuse.
Hence, we are using the Trigonometric function of Sine.
sin θ = Opposite side/ Hypotenuse side
sin 64 = 225 feet/ Hypotenuse
Cross multiply
sin 64 × Hypotenuse = 225 feet
Divide both sides by sin 64
Hypotenuse = 225 feet / sin 64
Hypotenuse = 250.33543661 feet
Approximately = 250.34 feet
Therefore, the length of the wire needed to reach from the top of the tower to the ground is 513.3 feet.
