Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:
A line is increasing, and goes upwards from left to right when m > 0
A line is decreasing, and goes downwards from left to right when m < 0
A line has a constant slope, and is horizontal when m = 0
A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m =
y2 - y1
x2 - x1

According to a soccer coach, 75% of soccer players
have had at least one sprained ankle. An athletic
trainer would like to investigate this claim. To do so,
the trainer selects a random sample of 125 college

99 of them have had at least one sprained ankle. The
=p trainer would like to know if the data provide
convincing evidence that the true proportion of college

the fastest 3 runners in a race qualify for the next event. how many different groups of Runners could advance to the next event from a race that has seven runners
Answer:
35 different groups of 3 runners can be selected
Step-by-step explanation:
Here, we want to simply calculate the number of 3 runners that can advance in a race from a total of 7
What we want to do here is to simply get different groups of 3
So, we have it that we simply want to know the number of different ways we can select 3 from a total of 7
We can simply use combination for this;
We have the general combinatorial as;
nCr = n!/(n-r)!r!
With respect to this particular question, n = 7 and r = 3
So we have;
7C3 = 7!(7-3)!3! = 7!/(4)!3! = 35
An airplane is 16,000 feet above the ground. It begins to descend at a rate of 140 feet per minute. Write an equation you could use to solve for x, the number of minutes it will take until the plane is 12,600 feet above the ground.
Answer:
16000=140x
It will take 90 minutes to hit 12,600 ft above ground.
Step-by-step explanation:
Just swap out 16000 for 12600. Then solve from there.

what is the slope of 10x-2y=8?
Answer:
Slope: 5
Step-by-step explanation:
Mark as brainllest
Answer:
x= 1 /5 y+ 4 /5
Step-by-step explanation:
Let's solve for x.
10x−2y=8
Step 1: Add 2y to both sides.
10x−2y+2y=8+2y
10x=2y+8
Step 2: Divide both sides by 10.
10x /10 = 2y+8 /10 x= 1 /5 y+ 4 /5

($2.50/cookie)(x), involving multiplication, not addition.
Answer:
Solution :-According to the question
Equation = y/x
Putting y as $2.50
= (2.50)x

Jack paid $4:00 for 6 pounds of apples. What is the ratio of the price of apples to the pounds of apples?
Answer:
you get 1.5 pounds of apples per dollar (1 pound and 8 ounces)
Step-by-step explanation:
6 and 4 will not work so we need to use decimals
since we have a gap of two, we need to be able to use it four times
2=0.5
1.5 x 4 = 6
or we could just divide it... never mind forget it
your answer is 1.5 pounds of apples per dollar

Distance: Jack and Jill start from the same point and walk in'opposite directions. Jack
walks 2 kmh faster than Jill. After 3 hours they are 30 kilometers apart. How fast did
each walk?
Answer:
t = 6 km/hour
And, J would be 4 km per hour
Step-by-step explanation:
Let us assume the speed of Tom be T
And, the Speed of Jim be J
Given that
T - J = 2 km /hr ...........(i)
After 3 hours distance between them = 30 km
As they are walking in the opposite direction
Thus,
Net speed =T + J
L ÷ (T+J) = 3
30 ÷ (T+J) = 3
T +J =10 ..............(2)
After solving these two equations
2T = 12
t = 6 km/hour
And, J would be 4 km per hour

square root of 34
Step-by-step explanation:
You're the magnitude or the norm of the vector AB so you will square the X and Y components and then add them and put them in a square root
so
5 squared is 25
(-3) squared is 9
25+9 is 34
so the answer is the square root of 34

Nate is exponentially gaining Twitter followers! His current amount of followers is 146. His followers are increasing at a 24% rate each day. Part 1: Is this a growth or decay problem? ( 1 point) Part 2: Which equation correctly represents this problem (2 points) A) y=146(24)x B) y=146(1.024)x C) y= 146(1.24)x
Answer:
(a) Growth
[tex](b)\ y = 146(1.24)^x[/tex]
Step-by-step explanation:
Given
[tex]a= 146[/tex] -- current
[tex]r = 24\%[/tex] --- rate
Solving (a): Growth or decay
The question says his followers increases each day by 24%.
Increment means growth.
Hence, it is a growth problem
Solving (b): Equation to represent the scenario.
Since the rate represents growth, the equation is:
[tex]y = a(1 + r)^x[/tex]
Substitute: [tex]a= 146[/tex] and [tex]r = 24\%[/tex]
[tex]y = 146 * (1 + 24\%)^x[/tex]
[tex]y = 146 * (1 + 0.24)^x[/tex]
[tex]y = 146 * (1.24)^x[/tex]
[tex]y = 146(1.24)^x[/tex]

I think it's -18 13/24 ?
Answer:
-18 13/24
Step-by-step explanation:
Looking at the two numbers, we need to find a common denominator. To do that, list the multiplies of both numbers & find the first one that is in common.
8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120
The first multiple 8 & 6 share is 24, so we'll use that as our denominator
-67/8 - 61/6
-201/24 - 244/24
(-201 - 244)/24
Subtract 244 from -201 to get -445.
-445/24
Convert -445/24 into a mixed number.
-18 13/24 is the answer to -8 3/8 - 10 1/6.
