Answer:
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.

A rental car agency charges $16 per day plus 14 cents per mile to rent a certain car. Another agency charges $23 per day plus 10 cents per mile to rent the same car. How many miles per day will have to be driven for the cost of a car from the first agency to equal the cost of a car from the second agency?
a) 175 miles per day
b) 1750 miles per day
c) 97.5 miles per day
d) 975 miles per day
Answer:
Step-by-step explanation:
The answer is 175 miles per day. I guessed on it and it was right :D
The number of miles per day that will have to be driven for the total cost of of a car from the first agency to equal the total cost of a car from the second agency is 175.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A rental car agency charges $16 per day plus 14 cents per mile to rent a certain car. Therefore, we can write,
Total charge for x miles = $16 + $0.14(x)
Another agency charges $23 per day plus 10 cents per mile to rent the same car. Therefore, we can write,
Total charge for x miles = $23 + $0.10(x)
Since it is needed to be found the number of miles that the car should be traveling so that the total cost from both the agencies is the same. Thus, equate the equation together,
$16 + $0.14(x) = $23 + $0.10(x)
16 + 0.14x = 23 + 0.10x
0.14x - 0.10x = 23 - 16
0.04x = 7
x = 7 / 0.04
x = 175 miles per day
Hence, the number of miles per day that will have to be driven for the total cost of of a car from the first agency to equal the total cost of a car from the second agency is 175.

A pair of shoes is on sale for 80% of the original price. The sale prive is $60. What was the original price?
Answer:
75
Step-by-step explanation:
You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price

Step-by-step explanation:
So the angles in a quadraleteral add to 360
so put this in as an equation
4x-10 +x+62 + 2x+ 68 +3x +10= 360
10x+130=360
10x = 230
x=23
then work out each angle to find the smallest
x +62 = 85
2x+68 = 114
3x+10 = 79

how do you solve (7x + 5) - (3x + 2)
Answer:
x = 0.75
Step-by-step explanation:
Simplifying
(7x + -5) + -1(3x + -2) = 0
Reorder the terms:
(-5 + 7x) + -1(3x + -2) = 0
Remove parenthesis around (-5 + 7x)
-5 + 7x + -1(3x + -2) = 0
Reorder the terms:
-5 + 7x + -1(-2 + 3x) = 0
-5 + 7x + (-2 * -1 + 3x * -1) = 0
-5 + 7x + (2 + -3x) = 0
Reorder the terms:
-5 + 2 + 7x + -3x = 0
Combine like terms: -5 + 2 = -3
-3 + 7x + -3x = 0
Combine like terms: 7x + -3x = 4x
-3 + 4x = 0
Solving
-3 + 4x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 4x = 0 + 3
Combine like terms: -3 + 3 = 0
0 + 4x = 0 + 3
4x = 0 + 3
Combine like terms: 0 + 3 = 3
4x = 3
Divide each side by '4'.
x = 0.75
Simplifying
x = 0.75
Answer:
When solving equations like this, you have to use a method called PEMDAS.
This stands for:
P- ParentesisE- ExponentsM- MultiplyD- DivideA- AdditionS- Subtraction(7x + 5) - (3x +2)
Let's work it out...
Step one) Distribute the equation
Distributing the equation helps simplify it and make solving much easier.
(7x−5) − 1(3x−2)
(7x−5) − 3x + 2
Step two) Eliminate the Parenthesis
Now that the equation is simplified, you can take out the Parenthesis.
(7x − 5) − 3x + 2
7x − 5 − 3x + 2
Step three: Add the numbers
Add the two whole numbers together (-5 + 2)
7x − 5 − 3x + 2
7x − 3 − 3x
Step four: Combine like terms
Combine like terms or the numbers with variables (7x - 3x)
7x − 3 − 3x
4x − 3
