What is the surface area of a triangular prism?Let h be the height and b be the base of the triangle. Let L₁, L₂, and L₃ be the length and W be the width of the rectangle. Then the surface area of the triangular prism will be given as,
Surface area = 2 Area of triangle + 3 Area of rectangle
Surface area = (h x b) + (L₁ + L₂ + L₃) x W
Sean must determine how much paint he will use to cover all of the edges of his ramp.
The surface area of the ramp is calculated as,
SA = (8 x 6) + (5 + 6 + 7) x 9
SA = 48 + 18 x 9
SA = 48 + 162
SA = 210 square cm
The surface area of the ramp will be 210 square cm. Then the correct option is B.

Solve and graph this inequality on a number line:
-3 (x + 4) = 15
Answers
Steps to solve:
-3(x + 4) = 15
~Distributive Property
(-3 * x) + (-3 * 4) = 15
~Simplify
-3x - 12 = 15
~Add 12 to both sides
-3x - 12 + 12 = 15 + 12
~Simplify
-3x = 27
~Divide -3 to both sides
-3x/-3 = 27/-3
~Simplify
x = -9

Describe the transformations that maps triangle A to triangle A'.
A.translate 7 units to left and then reflect over the x-axis
B.translate 5 units to left and then reflect over the x-axis
C.translaté 7 units to right and then reflect over the x-axis
D.translate 5 units to right and then reflect over the x-axis
Answers
Answer:
c
Step-by-step explanation:
moving the figure over 7 units would put it directly over the a'
after that you can reflect the a over the x axis
The correct option is C. Translate [tex]7 \ units[/tex] to the right and then reflect over the x-axis.
To determine the transformations that map triangle [tex]\( A \)[/tex] to triangle [tex]\( A' \)[/tex]
1. Translation:
Observe the horizontal distance between the corresponding points of triangles [tex]\( A \)[/tex] and [tex]\( A' \)[/tex].
Triangle [tex]\( A \)[/tex] is initially centered around [tex]\( x = 2 \)[/tex]., while triangle [tex]\( A' \)[/tex] is centered around [tex]\( x = 2 \)[/tex]
The horizontal distance from [tex]\(-5\)[/tex] to [tex]\(2\)[/tex] is [tex]\(7\)[/tex] units to the right.
2. Reflection:
Check the vertical positions of triangles [tex]\( A \)[/tex] and [tex]\( A' \)[/tex].
Triangle [tex]\( A \)[/tex] is above the x-axis while triangle [tex]\( A' \)[/tex] is below the x-axis. This indicates a reflection over the x-axis.
Thus, the correct transformation sequence is to translate triangle [tex]\( A \) 7 units[/tex] to the right and then reflect it over the x-axis.

a pizzeria stores flour in a 5-gallon container. Each pizza they make uses 7 cups of flour. can the cook at pizzeria make 12 pizzas without refilling the canister?
the canister holds cups and they need cups of flour to make 12 pizzas?
Answers
Answer:
The cook CANNOT make 12 pizzas without refilling the canister
Step-by-step explanation:
Please see the attached files for explanation
The pizzeria cook can make 12 pizzas without refilling the flour container.
The pizzeria stores flour in a 5-gallon container. Each pizza uses 7 cups of flour. To determine if the cook can make 12 pizzas without refilling, we need to calculate if 5 gallons of flour is enough.
Calculation:
5 gallons = 640 cups (since 1 gallon = 128 cups)
12 pizzas x 7 cups/pizza = 84 cups needed for 12 pizzas
Since the canister holds 640 cups and only 84 cups are needed for 12 pizzas, the cook can indeed make 12 pizzas without refilling.

1 gallon of water weighs 8 1/3 pounds
30 gallons of water weighs x pounds
Answers
30 gallons of water weighs 250 pounds.
To find the weight of 30 gallons of water, we can use the given conversion factor that 1 gallon of water weighs 8 1/3 pounds.
First, let's find the weight of 1 gallon of water in pounds:
1 gallon = 8 1/3 pounds
Now, we can calculate the weight of 30 gallons of water:
30 gallons = 30 x (8 1/3 pounds)
= 30 x (25/3 pounds)
= 250 pounds
Therefore, 30 gallons of water weighs 250 pounds.

A construction crew is lengthening a road. The road started with a length of 57 miles, and the crew is adding 4 miles to the road each day. Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 36 days.
Equation: ?
Total Length of the road after 36 days: ?
Answers
Answer:
L = 57 + 4D
After 36 days, the length of the road will be 201 miles.

Solve the system of equations. y= 2x -3 y= x^2 -3
Answers
Answer:
(0, - 3 ) and (2, 1 )
Step-by-step explanation:
Given the 2 equations
y = 2x - 3 → (1)
y = x² - 3 → (2)
Substitute y = x² - 3 into (1)
x² - 3 = 2x - 3 ( subtract 2x - 3 from both sides )
x² - 2x = 0 ← factor out x from each term
x(x - 2) = 0
Equate each factor to zero and solve for x
x = 0
x - 2 = 0 ⇒ x = 2
Substitute these values into (1) for corresponding values of y
x = 0 : y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )
x = 2 : y = 2(2) - 3 = 4 - 3 = 1 ⇒ (2, 1 )
Answer:
(0, - 3 ) and (2, 1 ) 100% correct
