Answer:
y = 7
Step-by-step explanation:
The equation of the line is y = 7 because since it's a horizontal line the y value will always stay the same, and the x value will always be changing. Therefore you could draw a line straight across the y-axis at 7

The area of a rectangle is a 40 square inches. The width of the rectangle is 4 inches more than the length. What are the dimensions of the rectangle?
Answers
Answer:
I think 10
Step-by-step explanation:
because 4 times 10 is 40 and 4 side so 10 for each side
The dimensions of the rectangle are 4.63 inches and 8.63 inches respectively.
Let the length of the rectangle be L.Let the width of the rectangle be W.Given the following data:
Area of a rectangle = 40 square inches.Translating the word problem into an algebraic equation, we have;
[tex]W = L + 4[/tex]
To find the dimensions of the rectangle:
Mathematically, the area of a rectangle is given by the formula;
[tex]Area = LW[/tex]
Substituting the values into the formula, we have;
[tex]40 = L(L+4)\\\\40 =L^2+ 4L\\\\L^2+ 4L -40=0[/tex]
Solving the quadratic equation by using the quadratic formula, we have the following values;
L = 4.63 or −8.63
Length, L = 4.63 inches.
For the width:
[tex]W = L + 4[/tex]
[tex]W = 4.63 + 4[/tex]
W = 8.63 inches

In general, how do the slopes of line segments in the image compare with the slopes of corresponding line segments in the preimage? What effect does the scale factor of the dilation have on the slopes, if any?
Answers
Answer:
The slopes of the line segments are the same before and after dilation. The value of the scale factor n does not affect the slopes in the image.
Step-by-step explanation:
Plato simple answer
The slopes of the line are the same before and after dilation. The value of the scale factor n does not affect the slopes in the image.
How does dilation works?Dilation of a figure will leave its sides get scaled (multiplied) by same number.
Dilation if, is from the center of the rectangle, then distance of all the points of the rectangle from its center will get scaled by that dilation factor.
Slope:
We know that the slope is the ratio of change in y-value and change in x-value.
So, after dilation

Length of line:
The length of line =x
so, it's length will become nx.

School A rented and filled 4 vans and 2 buses with 142 students. High School B rented and filled 2
vans and 4 buses with 206 students. Every van had the same number of students in it as did the
buses. Find the number of students in each van and in each bus.
Answers
Answer:
Find the number of students in each van and in each bus?
13 students can fit in van and 45 students can fit in bus
There were 13 students in each van and 45 students in each bus for both High School A and High School B.
Let's assume that the number of students in each van is "v" and the number of students in each bus is "b".
From the information given, we can form the following equations:
Equation 1: 4v + 2b = 142 (High School A)
Equation 2: 2v + 4b = 206 (High School B)
We can start by multiplying Equation 1 by 2 and Equation 2 by 4 to eliminate the "b" variable:
2 * Equation 1: 8v + 4b = 284
4 * Equation 2: 8v + 16b = 824
Now, we subtract Equation 1 from Equation 2:
(8v + 16b) - (8v + 4b) = 824 - 284
12b = 540
b = 540 / 12
b = 45
Substitute the value of "b" back into Equation 1:
4v + 2(45) = 142
4v + 90 = 142
4v = 142 - 90
4v = 52
v = 52 / 4
v = 13
Therefore, there were 13 students in each van and 45 students in each bus for both High School A and High School B.

Answers
Answer:
The correct answer is A. That fifty percent is a statistic.
Step-by-step explanation:
Statistics is the science that studies the collection of objective data from reality and its subsequent analysis for the extraction of specific information on the group from which the data were obtained. Thus, statistics obtains different samples (such as opinions, personal characteristics, etc.) of a certain group, and compares their results with the purpose of establishing objective parameters applicable to the entire society.
In this way, the fact that in a survey 50% of the respondents answer in a specific way constitutes a specific statistic regarding that sample, which can in turn be transferred to society as a whole.
Urgent! Line l is parallel to line m. If the measure of <6 is 75o, what is the measure of <1?
Answers
Answer:
m<1 = 105°
Step-by-step explanation:
<6 and <2 are corresponding angles. Therefore:
m<2 = m<6
Since m<6 = 75°, therefore, m<2 = 75°.
m<1 + m<2 = 180° (linear pair angles)
m<1 = 180° - m<2 (substitution property of equality)
m<1 = 180° - 75° (substitution)
m<1 = 105°

the breadth of a rectangular plot is 20 m less than its lengths find its dimensions if its perimeter is 120
Answers
Answer:
breadth = 25m
length= 35m
Step-by-step explanation:
perimeter is distance all round a figure
in a rectangle we have two pairs of opposite but equal lines
breadth = 2x( because of the two breadths in a rectangle) - 20
length = 2x( because of the two lengths in a rectangle)
perimeter = 2x + 2x - 20
120 = 4x - 20
120 + 20 = 4x
140 = 4x
35 = x
to get the dimensions, we have to divide by 2 as we took both parts of each dimension
breadth = 2x - 20
2
=2(35) - 20
2
= 70 - 20
2
= 50m
2
= 25m
length = 2x

= 2(35)

A total of 2,000 square feet is to be enclosed in two pens, separated by a chain link fence. The outside walls are to be constructed of brick. The brick wall costs $20 per linear foot and the chain link costs $4 per linear foot. Find the dimensions that minimize the construction cost
Answers
Answer:
Dimensions that minimize is; 20 ft x 100 ft
Step-by-step explanation:
Let the width and length be x and y respectively.
We are given area as 2000 Sq.ft.
Thus;
xy = 2000 - - - (eq 1)
We are told that the brick wall costs $20 per linear foot and the chain link costs $4 per linear foot. Thus;
C(x) = 20x + 4y
From eq(1),y = 2000/x
Thus;
C(x) = 20x + 4(2000/x)
C(x) = 20x + 8000/x
To minimize this, we will differentiate and equate to 0.
Thus;
C'(x) = 20 - 8000/x²
Equating to zeeo;
20 - 8000/x² = 0
20 = 8000/x²
20x² = 8000
Divide both sides by 20;
x² = 8000/20
x² = 400
x = √400
x = 20 ft
Putting 20 for x in eq 1,we have;
20y = 2000
y = 2000/20
y = 100 ft

Every bag of peanuts costs $3.55
Answers
Answer:
The constant is that every bag costs $3.55
Step-by-step explanation:
When the bag of peanuts costs $3.55 then Constant of proportionality is 3.55
What is constant of proportionality?The constant of proportionality is the ratio between two directly proportional quantities
Here,
Every bag of peanuts costs $3.55
Consider the number of bags = x
Cost of the peanut bag = y
Therefore
y is directly proportional to x
y = kx
Where k is the constant of proportionality
k = [tex]\frac{y}{x}[/tex]
if the cost of the one bag is $3.55
Then [tex]k=\frac{3.55}{1}[/tex]
k=3.55
Hence, When every bag of peanuts cost constant of proportionality is 3.55
