Step-by-step explanation:
Part A
A square pyramid surface area can be calculated using A = Lw (which gives you surface area of the base square) & 4 of A = bh/2 (which gives you surface area of the 4 triangles on the side)
This means overall A = Lw + 4(bh/2)
Length = L = 4"
Width = w = 4"
Base = b = w = L = 4"
Height = h = 6"
A = Lw + 4(bh/2)
A = Lw + 2bh This is the answer after simplifying
A = (4")(4") + 2(4")(6") This is the numerical expression.
A = 16" + 48" = 64" This is the numerical answer.
A square prism surface area can be found using 2 of A = Lw (which represents the surface area of the 2 squares) and 4 of A = Lh (which gives you the surface area of the 4 rectangles).
This means overall A = 2Lw + 4Lh
Length = L = 4"
Width = w = 4"
Height = h = 6"
A = 2Lw + 4Lh
A = 2(4")(4") + 4(4")(6") This is the numerical expression.
A = 128" This is the numerical answer.
Part B
To see the difference between the 2 polyhedrons, I will place them as follows.
Pyramid Area = A = (4")(4") + 2(4")(6")
Prism Area = A = 2(4")(4") + 4(4")(6")
The numerical expression shows that the surface area of the prism has one more square area (as represented by 4"x4"), and has 2 more rectangular area (as represented by 4"x6").
The difference of the 2 numerical expressions can be found using subtraction:
A = [2(4")(4") + 4(4")(6")] - [(4")(4") + 2(4")(6")]
A = (4")(4") + 2(4")(6")
Hope this helps.

The graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The equation y = 2ˣ⁻⁴ - 3 is an exponential function that has been shifted 4 units to the right and 3 units down from the basic exponential function y = 2ˣ.
If we change the -3 to a 3, we get the new equation:
y = 2ˣ⁻⁴ + 3
This new equation represents the original exponential function shifted 4 units to the right and 3 units up.
Therefore, the graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.

Answer:
120
Step-by-step explanation:
all angles of a triangle add up to 180. 180-15-45= 120.
:D
brainliest pls
Given :
Measure of an angle = 15°
Measure of the second angle = 45°
Let the measure of the third angle be x.
We know that :
▪︎Sum of all angles of a triangle = 180°[angle sum property]
Which means :
[tex] =\tt 15 + 45 + x = 180[/tex]
[tex] =\tt 60 + x = 180[/tex]
[tex] =\tt x = 180 - 60[/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 120°[/tex]
Thus, the measure of the third angle = 120°
Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.
Therefore, the correct option is (C) 120

Gavin wants to buy a jacket that sells for $38.95. An advertisement says that next week that jacket will be on sale for $22.50. How much will Gavin save if he waits until next week to buy the jacket?
Answers
Answer: Gavin will save $16.45 if he waits until next week to buy the jacket.
Step-by-step explanation:
Given: Current Market price of jacket = $38.95
Sales price next week = $22.50
Amount he can save = (Current Market price of jacket)- (Sales price next week )
i.e. Amount he can save = $ (38.95-22.50)
i.e. Amount he can save = $ 16.45
Hence, Gavin will save $16.45 if he waits until next week to buy the jacket.

If a dice is rolled 18 times, how many times is the number 2 expected to come up? *
A .2 times
B. 3 times
B. 6 times
D.9 times
Answers
Answer:
the answer is B. 3 times
that's what I think
Number of times 2 come, If a dice is rolled 18 times is 3 times. So, Option 'B' is the correct answer.
Probability based problem:Probability of a number = Number of outcome / Total number of outcomes
Probability of getting two = 1 / 6
Number of times 2 come, If a dice is rolled 18 times = 18[Probability of getting two]
Number of times 2 come, If a dice is rolled 18 times = 18[1/6]
Number of times 2 come, If a dice is rolled 18 times = 3 times

F(x)=3x-2 find f^-1(x) than find f^-1(13)
Answers
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 3x - 2 ( add 2 to both sides )
y + 2 = 3x ( divide both sides by 3 )
[tex]\frac{y+2}{3}[/tex] = x
change y back into terms of x with x = [tex]f^{-1}[/tex] (x)
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+2}{3}[/tex]
To evaluate [tex]f^{-1}[/tex] (13) substitute x = 13 into [tex]f^{-1}[/tex] (x) , that is
[tex]f^{-1}[/tex] (13) = [tex]\frac{13+2}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5
How many years will it take for $4,000 to double at a simple interest rate of 5%? Show your work.
Answers
Answer: in explination
Step-by-step explanation:
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
it will take 20 years
to check if you are right you would...
Check:
simple interest on $4000 for 20 years at 5%
= .05(20)(4000) = 4000
the amount = what we had + new amount
= 4000 + 4000 = 8000 which is double what we started with
So the answer would be it took 20 years.
