Answer:
[tex]\boxed{\sf m=-\cfrac{2}{3}}[/tex]
Step-by-step explanation:
In order to fins the slope we can either use the slope formula m = (y_2-y1)/(x2 – x1) or the standard line equation, y = mx + b to solve for the slope, m.
Using two points on the line, we can find the slope by finding the rise and the run
Slope formula :-
[tex]\boxed{\sf m=\cfrac{rise}{run} =\cfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf \left(x_1,\:y_1\right):\left(5,\:10\right)[/tex]
[tex]\sf \left(x_2,\:y_2\right):\left(2,\:12\right)[/tex]
[tex]\sf m=\cfrac{12-10}{2-5}[/tex]
[tex]\sf m=-\cfrac{2}{3}[/tex]

27 units
29 units
30 units
34 units
Answer:
The perimeter of the pentagon is;
29 units
Step-by-step explanation:
Let A, B, C, D, and E represent the vertices of the pentagon
The "x" and "y" coordinates of the vertices of the pentagon are given as follows;
A(-6, 2), B(-2, -2), C(5, -2), D(5, 2), E(-2, 5)
The length of the sides between each pair of coordinates can be found using the following formula;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, we have;
Length of segment AB = √((-2 - (2))² + (-2 - (-6))²) = 4·√2
Length of segment BC = √((-2 - (-2))² + (5 - (-2))²) = 7
Length of segment CD = √((5 - 5)² + (2 - (-2))²) = 4
Length of segment DE = √((5 - 2)² + (-2 - 5)²) = √58
Length of segment EA = √((5 - (2))² + (-2 - (-6))²) = 5
The length of the perimeter of the pentagon = 5+√58 + 4 + 7 + 4·√2 ≈ 29.2726273554 ≈ 29
The length of the perimeter of the pentagon ≈ 29.

Answer:
The answer is 35
Step-by-step explanation:
It wants to know how many basketball and baseball players there are. If there are 20 basketball players and the ratio is 4:3 then you need to divide the number of basketball players by 4 then multiply by 3. Add 20 to that number and the answer is C
Answer:
35
Step-by-step explanation:
I came up with 35 because 20/4= 5, so we are multiplying players by 5. Similarly, 3x5=15 for baseball players. 20 basketball players plus 15 baseball players is 35. I hope this helps!

If the measure of Angle B E C is (2 x + 3) degrees and x = 30, which expression could represent the measure of Angle A E D?
Lines A C and B D intersect at point E.
(4 x minus 3) degrees
(3 x minus 27) degrees
(5 x minus 33) degrees
(x + 43) degrees
Answer:
(3x−27)o
Step-by-step explanation:
we know that
m\angle BEC=m\angle AEDm∠BEC=m∠AED ----> by vertical angles
we have
m\angle BEC=(2x+3)^om∠BEC=(2x+3)o
The value of x is given
x=30
so
m\angle BEC=(2(30)+3)=63^om∠BEC=(2(30)+3)=63o
That means that the measure of angle AED is also 63 degrees
so
The expression that could represent the measure of Angle A E D is
(3x-27)^o(3x−27)o
because
For x=30
(3(30)-27)=63^o(3(30)−27)=63o
Answer:
(3x−27)o

260 lb
Step-by-step explanation:
180/9=20
13*20=260
Answer:
260 lbStep-by-step explanation:
Use the ratio
Earth : Mars = 180: 9Simplify
Earth : Mars = 20 : 1Find the weight x on Earth of the person with weight 13 lb on Mars:
20 : 1 = x : 13x = 20*13/1 = 260 lbHELP ❗❗ BRAINLISTED TO WHOEVER IS RIGHT

Answer:
The budget for dances is $380
Step-by-step explanation:
If we know that the ratio between student government budget for dance and charity event is 5:7 this means that there is some amount of money that fits 5 times into the student government budget for dance and 7 times into the budget for the charity events. So in order to find what is the value of that among we divide $532.00 by 7, and then multiply that amount by 5 to get the budget for the dance events. So we do........
$532.00 / 7 x 5 = $76 x 5 = $380

10 A solid metallic cylinder of radius 14 cm and
height 21 cm is melted and recast into equal
small spheres each of radius 7/2 cm. Find then
number of spheres formed.
Answer:
72 spheres are formed
Step-by-step explanation:
We start by calculating the volume of the metallic cylinder
Mathematically, we have this as;
V = pi * r^2 * h
V = pi * 21 * 14^2
V = 4116 π cm^3
The volume of each small sphere is;
V = 4/3 * pi * r^3
= 4/3 * π * 7/2^3 = 57.167 π cm^3
To get the number of small spheres, we simply divide the volumes
That will be 4116 pi / 57.167 pi = 72

The office supply superstore sells pens for 60 cents each and
pencils for 40 cents each. Diane purchased a total of 17 items
(pens and pencils) for $8.20. How many pens did Diane
purchase?
A 5
В 7
C 10
D
12
Answer:
Option B. 7
Step-by-step explanation:
In order to solve this question we first have to find out what is the difference between the prices of a pen and a pencil. SO we get...
60 - 4- = 20 cents
Now if we were to assume that all 17 items were pencils then Diane would pay....
17 x 0.40 = $6.8
But then he pays 8.2-6.8 = $1.4 less than he should be.
If we substitute one pencil with a pen the total will increase by 20 cents. From here we can easily get the number of pens by doing the following...
1.4 / 0.2 = 7 pens
Therefore option B is the right answer.
Diane purchased 7 pens and 10 pencils.
The selling price of pens is 60 cents each ($0.6) while it is 40 cents each for pencils ($0.4).
Let x represent the number of pens bought and y represent the number of pencils.
Since a total of 17 items was bought for $8.20, hence:
x + y = 17 (1)
0.6x + 0.4y = 8.2 (2)
Solving equations 1 and 2 gives:
x = 7, y = 10
Therefore Diane purchased 7 pens and 10 pencils.
