Jeremy is on the planning committee for the rock climbing club. He is putting together a trip where members can go outdoor rock climbing. He is trying to determine how high the group should climb and how long the trip should last. He calls multiple parks in the area that offer rock climbing and collects data on the height of the rock formations and the average time it takes people to reach the top and come back down. The data he found is shown.

Jordan works for a landscape company during his summer vacation. He is paid $12 per hour for mowing lawns and $14 per hour for planting gardens. He can work a maximum of 40 hours per week, and would like to earn at least $250 this week. If m represents the number of hours mowing lawns and g represents the number of hours planting gardens, write a system of inequalities that could represent the given conditions.
Answers
Answer:
m + g < 40
12m + 14g > 250
Step-by-step explanation:
Given : Jordan is paid $12 per hour for mowing lawns and $14 per hour for planting gardens.
Let m represents the number of hours mowing lawns and g represents the number of hours planting gardens.
He can work a maximum of 40 hours per week, and would like to earn at least $250 this week.
Then, the system of the inequality becomes
m + g < 40
12m + 14g > 250
Y= -0.5x+5 3x+5y=2 what’s the answer
Answers
Answer:
x = -46
Step-by-step explanation:
Y= -0.5x+5
3x+5y=2 [replace the "y" in this problem with the what "y" equals above]
3x + 5( -0.5x + 5) = 2
3x + -2.5x + 25 = 2
0.5x = -23

Answers
Answer:
m = -7/2
Step-by-step explanation:
If two lines are parallel, they have the same slope. The slope of r is -7/2 (y=mx+b), so the slope of r is also -7/2.

Mr. Brown made 5 trips to the sushi bar. On his first trip, he got 14 pieces of sushi. On his second trip, he got 12 pieces of sushi. On his third trip, he got 22 pieces of sushi. On his fourth trip he got 8 pieces of sushi. On his final trip, he got 24 pieces of sushi. What was the average (use the mean) number of pieces of sushi he got on each trip to the sushi bar?
Answers
Answer: 16 pieces.
Step-by-step explanation:
Suppose that we have a set with N numbers
{x₁, x₂, x₃, ..., xₙ}
The mean of this set is calculated as:
M = (x₁ + x₂ + x₃ + ... + xₙ)/N
In this case, our set is:
{14, 12, 22, 8, 24}
So we have N = 5.
The mean of this set will be:
M = (14 + 12 + 22 + 8 + 24)/5 = 16
The average/mean number of pieces of sushi he got on each trip is 16 pieces.

Brian bought beverages for his coworkers. On Monday he bought 3 sodas and 4 iced teas for $18. On Tuesday he bought 5 sodas and 2 iced teas for $16.
Answers
Answer:
what is the question
Step-by-step explanation:
Answer:
3x+4y=18 and 5x+2y=16
x=the cost of the sodas
y=the cost of the iced teas
then you do
3x+4y=18, and 10x+4y=32 (the equation is still equivalent to 5x+2y=16, you just doubled it)
next,
10x+4y=32
-3x-4y=-18 (once the y's match, make one negative and one positive)
which leaves you with:
7x=14
which means
x=2
Plug the x value back into the equation, for this I chose to plug it back into 3x+4y=18
3(2)+4y=18
6+4y=18
4y=12
y=3
so the final answer is x=2, and y=3

What is the volume of a rectangular prism that is 1 1/2 inches by 2 1/4 inches by 4 inches? Show your reasoning
Answers
help please someone
The volume of the rectangular prism is given by the equation
A = 13 1/2 inches³
What is the Volume of a Rectangle?
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
Let the volume of the rectangular prism be represented as A
Now , the equation will be
The length of the rectangular prism L = 1 1/2 inches
The length of the rectangular prism L = 1.5 inches
The width of the rectangular prism L = 2 1/4 inches
The width of the rectangular prism L = 2.25 inches
The height of the rectangular prism L = 4 inches
So , the volume of the rectangular prism A = Length x Width x Height
Substituting the values in the equation , we get
The volume of the rectangular prism A = 1.5 x 2.25 x 4
On simplifying the equation , we get
The volume of the rectangular prism A = 13.5 inches³
Hence , the volume of rectangular prism is 13.5 inches³

Li Juan solves the equation below by first squaring both sides of the equation.
13 - 2w = w + 6
What extraneous solution does Li Juan obtain?
will give 36 points HURRY PLEASE
Answers
Answer:
Step-by-step explanation:
(13-2w)^2 = 169 - 52w + 4w^2
(w+6)^2 = w^2 + 12w + 36
Setting them equal:
169 - 52w + 4w^2 = w^2 + 12w + 36
3w^2 - 64w + 133 = 0
Using the quadratic formula, we get
x = (64 +/- sqrt(64^2 - 4*3*133))/6
64^2-12*133 = 2500. sqrt(2500) = 50.
x = (64 +/- 50)/6.
x = 19 or 14/6 = 7/3.
Solving the original equation:
7 = 3w.
w = 7/3.
Therefore 19 is extraneous.
x = 19 is the extraneous solution Li Juan obtained.
The given equation is 13 - 2w = w + 6.
We need to solve the equation by squaring both sides of the equation.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, 13 - 2w = w + 6 squaring both sides of the equation.
That is, (13-2w)²= 169 - 52w + 4w²
(w+6)²= w²+ 12w + 36
Setting them equal, we get
169 - 52w + 4w² = w² + 12w + 36
⇒3w²- 64w + 133 = 0
Now, using the quadratic formula, we get
x = (64±√(64² - 4×3×133))/6
⇒x = (64±√2500)/6.
⇒x = (64±√50)/6.
⇒x = 19 or 14/6 = 7/3.
Solving the original equation, we get
7 = 3w⇒w = 7/3
Therefore, x = 19 is the extraneous solution Li Juan obtained.
