What is the rise-over-run value for the relationship represented in the graph?
a) 20
b) 30
c) 1/20
d) 1/30
Answers
Answer: 1/30 the rise over run is the slope wich means the y value over the x value and since you have 2 points you have to subtract the y values and put it over the subtracted x values
Step-by-step explanation:
Option B is correct,30 is the rise-over-run value for the relationship represented in the graph.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given two points are (4,120) and (2,60)
Let x₁=4, y₁=120,x₂=2,y₂=60
Substitute the values in slope formula
m=60-120/2-4
m=-60/-2
m=30
Hence 30 is the rise-over-run value for the relationship represented in the graph.

angle KHJ is equal to angle LJH, so by def. of isoceles triangle, 180-126 = 54/2 = 27 = angle KHJ = angle LJH. So Angle JKH is 180-(27+90), is 63. Angle HJL is 27. Angle LHK is 90- Angle KHJ, or 90-27, which is 63. Finally, Angle JLK is 27 because it's literally a reflection of triangle HMJ and LMK.

2x+8(x+3) = 3(x-13)
please show the work, i’ll mark brainliest
Answers
Answer:
x = -9
Step-by-step explanation:
2x + 8( x + 3 ) = 3( x - 13 )
Dstribute;
2x + 8 ( x + 3 ) = 3 ( x - 13 )
2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))
2x + 8x + 24 = 3x - 39
Combine like terms;
2x + 8x + 24 = 3x - 39
10x + 24 = 3x - 39
Inverse operations;
10x + 24 = 3x - 39
-3x -3x
7x + 24 = -39
-24 -24
7x = - 63
/7 /7
x = -9
2x+8x+24=3x-39
collect like terms, such as “2x+8x” this becomes 10x. plug in 10x.
10x+24=3x-39. now move variable and constant. 10x-3x=-39-24
collect like terms again. 10x-3x becomes 7x.
7x=-39-24.
-39-24=-63
7x=-63 divide both sides by 7.
x=-9

Answer:

Step-by-step explanation:
You can see in the picture a triangle is formed where the sides are AB, BC, and AC.
The side lengths you have are AC = 16 and BC = 20.
You can use the Pythagorean Theorem, [tex]a^2+b^2=c^2[/tex], so:
[tex]16^2+b^2=20^2[/tex]
[tex]256+b^2=400\\b^2=144\\b=12[/tex]
This means that the length of AB = 12.
It's asking the diameter, and AB is the radius, so you have to do 12 * 2 to find the diameter = 24 inches

In ∆DEF, ∠F = ∠D and EF = 4 cm and DF = 5 cm. Then find the length of DE
Answers
Answer:
DE = 4cm.
Step-by-step explanation:
The Isoscles Triangle Theorem says that:
"If two sides of a triangle are congruent, then angles opposite those sides are congruent."
The converse of this theorem is
"If angles opposite those sides are congruent, then two sides of a triangle are congruent."
Therefore, since ∠F is congruent to ∠D and are opposite sides ED and EF
while EF = 4 cm and DF = 5 cm.
DE = 4cm.

A dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 3 feet in length. How many 9-inch pieces can the dressmaker cut from 5 of these rolls of ribbon? Before you try that problem, answer the question below. How many \textbf{inches}inches of ribbon does the dressmaker have, in total?
Answers
Answer: 20
Step-by-step explanation:
First and foremost, we should know that: 12 inches = 1 foot. Therefore converting 3 feet to inches will be:
= 3 × 12 = 36 inches.
Therefore, if a dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 3 feet in length. The number of pieces will be:
= 3 feet / 9 inch
= 36 inches / 9 inches
= 4 pieces
Then, the number of 9-inch pieces that the dressmaker can cut from 5 of these rolls of ribbon will be:
= 4 × 5
= 20 pieces

A stadium has 55,000 seats. Seats sell for $28 in Section A, $16 in Section B, and $12 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,156,400 from each sold-out event. How many seats does each section hold?
Answers
Answer: Section A holds 27500 , Section B has 14100 and SEction C has 13400.
Step-by-step explanation:
Let x= Number of seats in section A.
y = Number of seats in section B.
z= NUmber of seats in sectionC.
As per given , we have
x+y+z=55000 (i)
x= y+z (ii)
28x+16y+12z=1156400 (iii)
Substitute value of x from (ii) in (i), we get
[tex]x+x=55000\\\\\Rightarrow\ 2x=55000\\\\\Rightarrow\ x=27500[/tex]
From (i)
[tex]27500+y+z=55000\\\\\Rightarrow\ y+z=55000-27500\\\\\Rightarrow\ y+z=27500 \ \ \ (iv)[/tex]
From (iii), we get
[tex]28(27500)+16y+12z=1156400 \\\\\Rightarrow\ 770000+16y+12z=1156400\\\\\Rightarrow\ 16y+12z=386400\\\\\Rightarrow\ 4y+3z=96600 \ \ \ \ (v)[/tex]
Multiply 3 to (iv), we get
[tex]3y+3z=82500\ \ \ \ (vi)[/tex]
Eliminate (v) from (iv), we get
[tex]y=14100[/tex]
from (iv)
[tex]14100+z=27500\\\\\Rightarrow\ z=13400[/tex]
Hence, Section A holds 27500 , Section B has 14100 and SEction C has 13400.
