what is the slope of the line that passes through the points (3,-20) and (5,8)?
Answer:
14
Step-by-step explanation:
The equation to find slope is [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. You plug in the values to get [tex]\frac{8-(-20)}{5-3}[/tex]. This simplifies to [tex]\frac{28}{2}[/tex], which is 14.
two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1600. what are the rate charged per hour by each mechanic. if the sum of the two rates are $215 per hour.
The rate charged per hour by the first mechanic = $105,
And the rate charged per hour by the second mechanic = $110.
Use the concept of ratio defined as:
A ratio indicates how many times one number contains another number. The ratio of two numbers is written as x: y, which is equivalent to x/y.
Where x and y are individual amounts of two quantities.
And, the Total quantity gives after combining as x + y.
Given that,
Two mechanics worked on a car.
The first mechanic worked for 10 hours.
The second mechanic worked for 5 hours.
Together, they charged a total of $1600.
The sum of the two rates charged per hour is $215.
Assume that,
The rate charged per hour by the first mechanic is = x dollars,
The rate charged per hour by the second mechanic is = y dollars.
The first mechanic worked for 10 hours,
The total amount earned by the first mechanic would be 10 times their hourly rate = 10x dollars.
Similarly,
The second mechanic worked for 5 hours,
The total amount earned by the second mechanic would be 5 times their hourly rate = 5y dollars.
Set up two equations based on the given information:
The first equation is the sum of the two rates, which is,
x + y = 215 ......(i)
The second equation is the total amount earned by both mechanics,
10x + 5y = 1600 .....(ii)
Use substitution to find the values of x and y:
From the first equation, we can express x in terms of y as,
x = 215 - y
Substitute this value of x into the second equation:
10(215 - y) + 5y = 1600
Expanding the equation, we get,
2150 - 10y + 5y = 1600
Combining like terms, we have:
-5y = 1600 - 2150
-5y = -550
Dividing both sides of the equation by -5, we get:
y = 110
Now that we have the value of y,
Substitute it back into the first equation to find x:
x + 110 = 215
Subtract 110 from both sides, and we get:
x = 105
Hence,
The rate charged per hour by the first mechanic is $105, & the rate charged per hour by the second mechanic is $110.

Step-by-step explanation:
The very first thing you have to realize is that the temperature goes further down the minus scale which means that only A and D can be correct. That's because time in this question is positive.
So if you just try the first value (x = 3), you will get
-3/2 * 3 = -9/2 which would mean that you would add -4 1/2 onto - 10 which is much larger than - 10
A: is not the answer.
-2/3 * 3 - 10 = -6/3 - 10 = -2 - 10 = - 12
That is the answer you should get. The answer is D.

Answer:
x = 10
Step-by-step explanation:
We know that in a parallelogram base angles are supplementary angle (add up to 180°)
Given that;
∠U = 9x + 15
∠V = 6x + 15
we can say that:
∠U + ∠V = 180°
(9x + 15) + (6x + 15) = 180
Combining like terms we get;
15x + 30 = 180°
15x = 180 - 30
15x = 150
x = 150/15
x = 10

Answer:
$12
Step-by-step explanation:
At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter. F(d), models the fee (in dollars) for climbing d meters. F(d)=110+0.12d, What is the increase in price for every 100 meters climbed?
Given:
F(d) = 110 + 0.12d
Where,
F(d) = the fee (in dollars)
d = number of meters climbed
What is the increase in price for every 100 meters climbed?
F(d) = 110 + 0.12d
$110 is the fixed fee
0.12 is the increase in price per meter.
Increase in price per 100 meters climbed = 0.12d
= 0.12 × 100
= 12
Increase in price per 100 meters climbed = $12

What is the volume of this prism
Hi there!
[tex]\large\boxed{\text{A. } 320 cm^3}[/tex]
We can begin by finding the area of the base in order to solve for the volume.
Use the formula for the area of a trapezoid:
A = 1/2(b1 + b2)h
Substitute the given values:
A = 1/2(10 + 6)5
A = 1/2(16)5
A = 40 cm²
Multiply by the depth of the prism to solve for the volume:
40 × 8 = 320 cm³

While painting the side of his house, Jason positioned his ladder so that the top was 16 feet
above the ground, while the bottom was 12 feet away from the base of the wall. To reach a
spot higher up on the house, Jason moved the ladder so that the top was 18 feet above the
ground. How much closer to the house is the bottom of the ladder now?
The bottom of the ladder is now 96 feet closer to the house compared to its initial position.
To solve this problem, we can use the concept of similar triangles. Let's denote the distance between the bottom of the ladder and the base of the wall as x (in feet). We are given the following information:
Initial ladder position:
Top of the ladder is 16 feet above the ground.
Bottom of the ladder is 12 feet away from the base of the wall.
New ladder position:
Top of the ladder is 18 feet above the ground.
Since the triangles formed by the ladder, the ground, and the wall are similar, we can set up a proportion to find the new distance between the bottom of the ladder and the base of the wall.
Using the initial position of the ladder:
(16 ft) / (x + 12 ft) = (18 ft) / (x)
Cross-multiplying:
16 ft * x = 18 ft * (x + 12 ft)
Expanding:
16x = 18x + 216 ft
Moving the terms involving x to one side:
16x - 18x = 216 ft
Simplifying:
-2x = 216 ft
Dividing by -2:
x = -108 ft
Since distance cannot be negative, we discard the negative solution. The distance between the bottom of the ladder and the base of the wall is 108 ft.
Now, to find how much closer to the house the bottom of the ladder is, we can subtract the initial distance (12 ft) from the new distance (108 ft):
108 ft - 12 ft = 96 ft

A manager at a shipping company will purchase boxes in the shape of right rectangular prisms. He wants the volume of each box to be exactly 98 cubic feet. Which figure shows a box with the dimensions, in feet (ft), that the manager will purchase?
You have 4 options... which one do you think is correct
winner gets brainlest!! along with 50 points
Answer:
the first one
Step-by-step explanation:
To find the answer we want to find the volume of each rectangular prism
Which ever prism has an exact volume of 98 is the correct answer
( note that volume of a rectangular prism = length times width times height )
For the first answer choice
4 * 3.5 * 7 = 98
We get an outcome of 98, which means that the first one could possibly be the correct answer however lets find the volume of the rest of the prisms just to be safe.
For the second one
6.25 * 7 * 2 = 87.5
87.5 ≠ 98 therefore the second choice is not correct
For the third one
3 * 6.5 * 5 = 97.5
97.5 ≠ 98 therefore the third choice is not correct
For the fourth one
7.5 * 1 * 14 = 105
105 ≠ 98 therefore the fourth choice is not correct
So we can conclude that the first answer choice is correct
