Answer:
Length = 13 in
Width = 10 in
Step-by-step explanation:
Let L be the length.
Let W be te width.
From the question given above, the Lenght is 3 more that the width i.e
L = 3 + W
Next, we shall determine the width (W). This can be obtained as follow:
Length (L) = 3 + W
Width (W) = W
Area (A) = 130 in²
A = L × W
130 = (3 + W) × W
Clear bracket
130 = 3W + W²
Rearrange
W² + 3W – 130 = 0
Solving by formula method
W = –b ± √(b² – 4ac) / 2a
a = 1
b = 3
c = –130
W = –3 ± √(3² – 4 × 1 × –130) / 2 × 1
W = –3 ± √(9 + 520) / 2
W = –3 ± √(529) / 2
W = –3 ± 23 / 2
W = –3 + 23 / 2 or –3 – 23 / 2
W = 20/2 or –26/2
W = 10 or –13
Since measurement can not be negative, the width is 10 in.
Finally, we shall determine the length. This can be obtained as follow:
L = 3 + W
W = 10
L = 3 + 10
L = 13 in
SUMMARY
Length = 13 in
Width = 10 in

Step-by-step explanation:
Hallar x + y
Es de geoemtria, angulos
Answer:
1). x = 40
2). y = 20
Step-by-step explanation:
1). "4x" y "160" son ángulos de vértice, por lo que son congruentes entre sí. Entonces, "4x = 160" y luego usa álgebra para resolver "x" y "x = 40".
2). "Y" y "4x" son ángulos suplementarios, por lo que si ambos se suman, forman un ángulo de 180. Entonces, "Y + 4 (40) = 180", usando álgebra daría la respuesta "Y = 20".

Find the area of this trapezoid. Be sure to include the correct unit in your answer.
Answer:
A = 55 in²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 5, b₁ = 5 and b₂ = 17 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (5 + 17) = 2.5 × 22 = 55 in²
Answer: 55
Step-by-step explanation: A=a+b
2h=5+17
2·5=55

Meg plotted the graph below to show the relationship between the temperature of her city and the number of sweaters sold at a store:
Main title on the graph is Sweater Sale. Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.
Part A: In your own words, describe the relationship between the temperature of the city and the sale of sweaters in the city. (5 points)
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate slope and y-intercept. (5 points)
Solution:
The description about the graph is:
Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.
Part A: The relationship between the temperature of the city and the sale of sweaters in the city can be found by drawing the line of best fit.
If you will draw line through , (12.5,6) and (15,4), it will best represent line of best fit, because most of points on same and opposite side of line are equidistant from each other.
Equation of line passing through two points,[tex](x_{1},y_{1}),(x_{2},y_{2})is, \frac{y-y_{1} }{x-x_{1} } = \frac({y_{2} - y_{1}})({x_{2}-x{1} })[/tex]
Equation of line passing through (12.5,6) and (15,4) is given by
[tex]\frac{y-6}{x-12.5} = \frac{6-4}{12.5-15}[/tex]
[tex]2x-25=-2.5+15[/tex]
[tex]2x+2.5y=40[/tex]
[tex]20x+25y= 400[/tex]
[tex]4x+5y=80[/tex]
Part B: Description of line of best fit
A line of best is the line which passes through all or some points or only through a single point, which describes the relationship between x and y values of data set. The line passes through (12.5,6), (15,4),and (7,10) that is three points.
(C) 4 x + 5 y=80
5 y= - 4 x +80
[tex]y=\frac{-4x}{5}+16[/tex]
Slope [tex]= \frac{-4}{5}[/tex], Y- intercept = 16

Ms. Leeper gives her sixth- and seventh-grade students a geography test to decide who will represent her class in the school geography bee. The line plots below show the results of the test for her sixth-grade class and seventh-grade class, respectively.
The data for each grade have the same interquartile range (IQR). Which of the following best compares the two test score distributions?
A - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
B - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
C - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
D - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.

Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Probability of rolling an even number P(A):
[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Probability of flipping tails P(B):
[tex]\frac{1}{2}[/tex]
P(A OR B) = P(A) + P(B) – P(A AND B)
[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) = [tex]\frac{3}{4}[/tex]

She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.
Divide. Write the quotient in lowest terms.

The length of a rectangle is 3 times its width. What is the length of the rectangle if the area is 48 square centimeters?
Answer:
length=12
Step-by-step explanation:
length=3w
A=48
48=3w(w)
48=3w^2
16=w^2
W=4
48/4=12
length=12
