What Is the slope of the line on the graph?
Answer:The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

a wheel has diameter 84cm.During a journey the wheel make 800 complete revolutions. how many meter does it travel?
Answer:
2110.08 meters
Step-by-step explanation:
find the circumference of the wheel
Divide 84 by 2 to find the radius.
84/2=42
C=2πr
C=2(3.14)(42)
C=263.76 cm
263.76*800=211008cm
Divide by 100 to convert to meters
211008/100=2110.08
2110.08 Meters

2. Deon wants to find the perimeter of a square with side length 6m - 3. Write two expressions that represent the perimeter, including one expression in simplest form. Perimeter of a square- p = 4(s) or p = s + s + s + s
Step-by-step explanation:
The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
The expressions that represent the perimeter of the square are p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.
What is perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given:
The side of the square is 6m-3 unit.
And all the sides of the squares are equal.
And the perimeter p of the square is,
= the sum of all the sides.
p = 4 x one side.
p = 4(6m-3)
The above expression represents the perimeter of the given square.
Simplifying,
p = 24m - 12
This is the simplest form of the expression.
Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.

Jennifer has run many marathons and keeps track of all of her finishing times. At a marathon last month, she finished in 350 minutes. The other day, she ran another marathon and finished with a time of 406 minutes. What is the percent of increase in Jennifer's marathon time?
Answer:
16%
Step-by-step explanation:
406 / 350 = 1.16
406 is 116% of 350
so 350 + 16% is 406
because 350 * 0.16 = 56
56 is 16%
350 + 56 = 406

Answer:
I Had A Problem In This Too Lol Here Was Correct For Me
Step-by-step explanation:
Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).
Input the values into the formula. This gives us (10 - 8)/(-2 - 3).
Subtract the values in parentheses to get 2/(-5).
Simplify the fraction to get the slope of -2/5.
Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}x_{1} }[/tex]
with (x₁, y₁ ) = (- 10, 9 ) and (x₂, y₂ ) = (-12, 7 )

Answer:

Step-by-step explanation:
[tex]u(t) = 7t - 2 \\ u(2) = 7(2) - 2 \\ u(2) = 14 - 2 \\ u(2) = 12 \\ \\ s(t) = {t}^{2} - 9 \\ s(u(2)) = {(12)}^{2} - 9 \\ s(u(2)) = 144 - 9 \\ \\ s(u(2)) = 135[/tex]

For the functions u(t) = 7t - 2 and s(t) = t² - 9. s(u(2)) = 135
What is a function?A function is a mathematical equation that shows the relationship between two variables.
For the functions u(t) = 7t - 2 and s(t) = t² - 9.To find what is s(u(2)), we proceed as follows.
Since u(t) = 7t - 2. Then u(2) is evaluated when t = 2. So, we have that
u(t) = 7t - 2
u(2) = 7(2) - 2
u(2) = 14 - 2
u(2) = 12
Now, since u(2) = 12 and s(t) = t² - 9
s(u(2)) is evaluated as follows
s(t) = t² - 9
s(u(2)) = 12² - 9
s(u(2)) = 144 - 9
s(u(2)) = 135
So, s(u(2)) = 135

Answer:
E see below
Step-by-step explanation:
When dividing two fractions, you flip the second fraction over then multiply.
So the equation would then be:
3xy (2 + y) ab
--------------- X --------------
2ab 3xy
The 3xy on top and bottom cancel each other out. The ab on top and bottom cancel each other out.
So you are left with:
2 + y
-------
2
Answer: Number E is correct.
Step-by-step explanation:
division becomes multiplication and turns upside down. ab cuts ab and 2 remains as denominator. 3xy cuts 3xy and 2+y remains as numerator. Therefore the answer obtained is 2+y/2.

Anyone know these answers for math??
Answer:
7) No
8) Yes
Step-by-step explanation:
7) 15 + 2y = -12 - 4y when y = -0.5
15 + (2*-0.5) = -12 - (4*-0.5)
15 + -1 = -12 - (-2)
15 - 1 = -12 + 2
14 = -10
The numbers are different on both sides so -0.5 is not a solution
8) 5 - 2( 3x + 5 ) = 3 - 10x when x = 2
5 - 2( (3*2) + 5 ) = 3 - (10*2)
5 - 2( 6 + 5 ) = 3 - 20
5 - 2*11 = 3 - 20
5 - 22 = 3 - 20
-17 = -17
The numbers are similar on both sides so 2 is a solution

what is one way to find the number of minutes in 7 hours?
Answer:
Seven dived by 60
Step-by-step explanation:
60 minutes makes an hour, so if you divide 7 hours by 60 minutes you could easily get an answer.
Multiplication.
because 1 hour = 60 minutes
and for you, there is 7 hours, you'd just do 7 x 60.
The answer would be the number of minutes (in those seven hours).
7 x 60 is 420 minutes just in case you were wondering.

8² + altitude² = (2√41)²
64 + altitude² = 2²*(√41)² {(√41)² = √41*√41 = 41}
64 +altitude² = 4 * 41
64 +altitude² = 164
altitude² = 164 - 64
