Two lines are perpendicular if and only if the product of their slopes is . In other words, the slope of a line that is perpendicular to a given line is the negative reciprocal of that slope. Thus, for a line with a given slope of 3, the line perpendicular to that slope must be the negative reciprocal of 3, or .

Write an inequality that represents the total cost of Ben’s birthday for p people given his budget.
Answers
Answer:
45+5.50p=80
Step-by-step explanation:
45 is the flat fee and 5.50 is the shoe rental and unlimited bowling, so p is next to that because its 5.50 PER person so if ben had 2 people it would be 5.50 times 2 plus 45. But remember it cannot be over 80. please mark brainliest

The table shows the balance of two accounts each year for four years. Determine whether each balance is linear or nonlinear. Then predict which account will have a greater balance in Year 3.
Year, t Account A Balance Account B Balance
0 $450 $550
1 $504 $570
2 $564.48 $590
Account A Balance is linear. Account B Balance is nonlinear. Account A will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3.
Account A Balance is linear. Account B Balance is nonlinear. Account B will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account B will have a greater balance in Year 3.

Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3. Then the correct option is B.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
The slope for account A is calculated as,
m = (504 - 450) / (1 - 0) = (564 - 504) / (2 - 1)
54 ≠ 60
Account A is non-linear. The amount after 3 years will be more than $620 ($564 + $60).
The slope for account B is calculated as,
m = (570 - 550) / (1 - 0) = (590 - 570) / (2 - 1)
20 = 20
Account A is linear. The amount after 3 years will be $610 ($590 + $20).

Find the surface area of the triangular prism shown below.
Answers
Answer:
the surface area is 544 square units
Step-by-step explanation:
the tringles first
12 x 8 = 96
base
12 x 14 = 168
sides
10 x 14 x 2 = 280
96 + 168 + 280
im going to break it down
000 + 100 + 200 = 300
90 + 60 + 80 = 230
6 + 8 + 0 = 14
300 + 230 = 530
530 + 14 = 544
The surface area of the triangular prism is equivalent to 330 units square.
What is a triangular prism?A triangular prism is a 3D shape with two identical faces in the shape of a triangle connected by three rectangular faces.
Given is a triangular prism as shown in the image.
We can calculate the surface area of the triangular prism as follows -
A{P} = {2 x A(T)} + {2 x A(R)} + A{B}
A{P} = {2 x 1/2 x 12 x 8} + {2 x 14 x 10} + {14 x 12}
A{P} = 12 x 8 + 2 x 140 + 14 x 12
A[P} = 4{3 x 2} + 2(7 + 6) + 280
A[P} = 24 + 26 + 280
A{P} = 330 units square
Therefore, the surface area of the triangular prism is equivalent to 330 units square.

Answer:
Here a = 20,, b= 8
Step-by-step explanation:
Using Pythagoras theorem,
a^2 + 15^2 = 25^2 ,, b^2 + 6^2 =10^2=100
Answer:
a = 20, b = 8
Step-by-step explanation:
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
(1)
a² + 15² = 25²
a² + 225 = 625 ( subtract 225 from both sides )
a² = 400 ( take the square root of both sides )
a = [tex]\sqrt{400}[/tex] = 20
(2)
b² + 6² = 10²
b² + 36 = 100 ( subtract 36 from both sides )
b² = 64 ( take the square root of both sides )
b = [tex]\sqrt{64}[/tex] = 8
