Let x = the smaller number.
Let 4+3x = the larger number.
So, 28 = 4+3x - x
24 = 2x
x = 12.
The smaller number is 12, now we need to find the larger number,
4+3(12)
40
So, the numbers are 12 and 40.
The equation can be solved by setting up two equations based on the information given, and then substitifying and simplifying the equations to solve for the two numbers. The two numbers are 12 and 40.
Explanation:
The subject of this question is dealing with equations in mathematics. To problem-solve this, we can first form an equation based on the information given: The larger number is equal to 'four more than three times the smaller number' and 'the difference between the two numbers is 28'.
So we can set up two equations:
Larger Number (L) = 3* Smaller Number (S) + 4 Larger Number (L) - Smaller Number (S) = 28By substituting the first equation into the second, it resolves as:
3S + 4 - S = 28
which simplifies to:
2S = 24
So, the smaller number S = 24/2 = 12. Substituting S = 12 into the first equation gives:
L = 3*12 + 4 = 36 + 4 = 40
So the two numbers are 12 and 40.

Yoko drove 522 miles in 9 hours. At the same rate, how many miles would she drive in 13 hours?
Yoko would drive 754 miles in 13 hours.
First you would have to find how many miles Yoko drives per hour so you divide 522 miles/9 hours to get 58 miles per 1 hour. Then you multiply 58 * 13 to get 754 miles.
what is 2 and 3/5 equal to in decimals
2 and 3/5 is equal to 2.6.
Being as the 2 is in front of the fraction, it is the whole number. This means in decimal form, it is to the left of the decimal point. Since there is no "fifths place" in a decimal, you must make it so it can go under the tenths, hundreths, thousanths or another place within the right side of the deciamal point. Simply multiplying 3/5 by 2/2 will give you 6/10. 6/10 as a decimal, is 0.6. Finally, add 0.6 and 2 together. Thus making 2.6 the answer.

The figure below shows the penalty box and the goal box of a soccer field. The penalty box is the largest rectangle
Part (A):
The area of the penalty box.
The dimensions of the penalty box are (15x-1) and (5x-7)
The area of rectangle = length * width
∴ The area of the penalty box = (15x-1) * (5x-7) = 75 x² - 110 x + 7
===================================================
Part (B):
The area of the goal box.
The dimensions of the goal box are (7x-1) and (x+3)
The area of rectangle = length * width
∴ The area of the goal box = (7x-1) * (x+3) = 7x² + 20x - 3
=======================================================
Part (C):
The area of the penalty box not coverd by the goal box =
The area of the penalty box - The area of the goal box =
(75 x² - 110 x + 7) - (7x² + 20x - 3) = 68 x² - 130 x + 10
A two-way frequency table shows grades for students in college and students in high school: High school College Total GPA above 3.0 14 26 40 GPA below 3.0 46 14 60 60 40 100 Based on this data, are "being in high school" and "GPA above 3.0" independent events?
Answer:
No, the two events "being in high school" and "GPA above 3.0" are not independent.
Step-by-step explanation:
If two events A,B are independent [tex]P(A|B)=P(A)[/tex]
P(high school | above 3.0) = [tex]\frac{14}{40}=0.35[/tex]
P(high school) = [tex]\frac{60}{100}=0.6[/tex]
So,0.35 ≠ 0.6
Since P(high school | above 3.0) ≠ P(high school), the events "being in high school" and "GPA above 3.0" are not independent.
The proportion of high school students with a GPA above 3.0 differs from the proportion of college students with a GPA above 3.0. Therefore, the events 'being in high school' and 'GPA above 3.0' are not independent according to the data provided.
To determine if "being in high school" and "GPA above 3.0" are independent events, we can check if the proportion of high school students with a GPA above 3.0 is the same as the proportion for college students. If the events are independent, the proportions should be equal.
From the two-way frequency table provided, we can calculate the proportions. There are 60 high school students and 40 college students. Among these, 14 high school students and 26 college students have a GPA above 3.0.
The proportion of high school students with a GPA above 3.0 is 14 out of 60, which simplifies to about 0.233.
The proportion of college students with a GPA above 3.0 is 26 out of 40, which simplifies to about 0.650.
Because these proportions are not equal, we can conclude that the events are not independent. Being in high school appears to have an impact on whether a student has a GPA above 3.0, based on this data set.
Therefore, the events 'being in high school' and 'GPA above 3.0' are not independent according to the data provided.

Find the coordinates of the point of intersection of the graphs of lines with y=−2x+7 and y=0.5x−5.5
the coordinates of the point of intersection of the graphs of lines with
y=−2x+7 and y=0.5x−5.5
to find intersection we solve for x and y
We replace -2x+7 for y in the second equation
−2x+7 =0.5x−5.5
Subtract 0.5x from both sides
-2.5x + 7 = -5.5
Subtract 7 on both sides
-2.5x = -5.5 - 7
-2.5x = -12.5
divide by -2.5 from both sides
x = 5
Plug in 5 for x in y=−2x+7
y=−2(5)+7
y = -10 + 7
y = -3
The point of intersection is (5,-3)
a fence is 702 m long. it is cut into three parts. two parts are the same length and the third is 27 m longer than either of the other two. find the length of each part
Answer:
225, 225 and 252 meters
Step-by-step explanation:
Let length of the 2 equal parts be each x m, then:-
2x + x + 27 = 702
3x = 702 - 27 = 675
x = 675/3
x = 225
So lengths of each parts are 225, 225, 252
To find the lengths of the three parts, we let the length of each of the two equal parts be 'x' and set up the equation 3x + 27 = 702. Solving for 'x' gives us that each of the two equal parts is 225 m, and the third part is 252 m.
The student is asking to find the lengths of three parts of a fence that has been cut, with two parts being equal in length and the third part being 27 m longer than the other two. Let's assume each of the two parts that are the same length is 'x' meters. Since the third part is 27 m longer, it would be 'x + 27' meters. According to the problem, the total length of the fence is 702 m.
Therefore, the sum of all three parts is:
x + x + (x + 27) = 702
Simplifying this, we get:
3x + 27 = 702
Subtract 27 from both sides:
3x = 675
Now, divide both sides by 3:
x = 225
So, the two equal parts are each 225 m long, and the third part is 225 + 27 = 252 m long.
To rent a certain meeting room, a college charges a reservation fee $18 and an additional fee of five dollars per hour. The chemistry club want to spend less and $78 on renting the room what are the possible numbers of hours in the chemistry club convention for the meeting room
This problem would be best modeled by an inequality.
Let t = the number of hours.
18 + 5t < 78
5t < 60
t < 12
The way the question sounds, it would not be a lessthan or equal to, because they want to spend less than 78. It would be a less than or equal problem if they said "no more than 78"
find two consecutive odd integers whose product is 1443
Let's x represents the first odd integer
The next consecutive integer would be represented as x+2.
So x and x+2 being multiplied together will give us 1443:
(x)(x+2)=1443
x^2+2x=1443
x^2+2x-1443=0
By solving the quadratic equation using the quadratic formula, x will equal to 37 and -39.
Since the problem says "integers", so I'm assuming two pairs of consecutive integers would be ok.
With that said you 1st pair will be: 37,39
Your second pair will be: -37,-39.

Riding with the wind at her back, a cyclist takes an hour less time to cover 80 miles than without any wind. Riding with the wind increases the cyclist's speed by 2 miles per hour. What is her speed when riding with the wind?
Answer:
41 MPH
Step-by-step explanation:
Let's assume the original speed with or without, is around 82 miles, within 2 hours.
So in this case, it'd be half the miles, half the hours!
Solution:
Let the speed of cyclist without any wind = x miles per hour
Speed of cyclist when speed of wind increases by 2 miles per hour = (x + 2 )miles per hour
Also , relation that is given between speed of cyclist without wind and with wind is :Riding with the wind at her back, a cyclist takes an hour less time to cover 80 miles than without any wind.
Converting this statement into terms of equation:
[tex]\frac{80}{x}-\frac{80}{x+2}=1 \\\\ 160 = x^2 + 2x \\\\ x^2 + 2x - 160=0 \\\\ x= \frac{-2\pm\sqrt{4+640}}{2}, {\text {As speed can't be negative, so taking positive value of x}} Gives, x =11.68[/tex]→→→To solve the Quadratic equation of type : a x² + b x + c=0, I have used discriminant method, to find the roots, which is x= [tex]\frac{-b\pm\sqrt{D=b^2-4ac}}{2a}[/tex]
Speed of cyclist without wind = 11.68 miles per hour
Speed of cyclist when wind is flowing = 11.68 +2 = 13.68 miles per hour

increase or decrease 32 pages to 28 Pages round to the nearest tenth of a percent
Final answer:
The number of pages decreased from 32 to 28, which is a difference of 4 pages. Dividing by the initial number of pages and multiplying by 100 gives a decrease of 12.5%.
Explanation:
To calculate the percentage change when the number of pages in a document decreases from 32 to 28, we follow these steps:
Find the difference between the two numbers. In this case, it is 32 pages - 28 pages = 4 pages.Divide the difference by the initial number of pages. So, we do 4 pages / 32 pages = 0.125.Multiply the result by 100 to get the percentage. Thus, 0.125 * 100 = 12.5%.Since the number of pages decreased, it is a 12.5% decrease.Therefore, there is a 12.5% decrease when a document goes from 32 pages to 28 pages.
Use the equation y = 4x to answer the questions.
The slope is 4 and the Y-Intercept is 0.
