The perimeter of a rectangle is 126 ft. The ratio of its length to its width is 5 : 4. What are the dimensions of the rectangle? 30 ft by 33 ft 35 ft by 28 ft 6 ft by 60 ft 3 ft by 60 ft
The length and width of the given rectangle will be 35 and 28 feet respectively.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
The perimeter of the rectangle = 2( length + width).
It is known that,
The perimeter of the rectangle = 2( length + width).
2(L + W) = 126
L + W = 63
The ratio of length to width,
L/W = 5/4
L = 5/4 W
(5/4 )W + W = 63
W(1 + 5/4) = 63
W = 63(4/9)
W = 7 x 4 = 28
And, L = 63 - 28 = 35
Hence "The length and width of the given rectangle will be 35 and 28 feet respectively".

Samir knows that the volume of prism is 40 cubic units . He also knows that the width can of the prism is 2 units and the height is 5 units. What is the length of the prism?
Final answer:
The length of the prism is 4 units, which is determined by dividing the volume of the prism (40 cubic units) by the product of its width (2 units) and height (5 units).
Explanation:
Samir knows that the volume of a prism is 40 cubic units, the width is 2 units, and the height is 5 units. To find the length of the prism, we can use the formula for the volume of a prism: V = lwh, where V is the volume, l is the length, w is the width, and h is the height. Plugging in the known values, we get 40 = l × 2 × 5. To solve for l, we divide both sides of the equation by the product of the width and height (2 × 5), yielding l = 40 / (2 × 5) = 40 / 10 = 4 units. Thus, the length of the prism is 4 units.

In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.
Answer:
D
Step-by-step explanation:
As the number of hours spent working increases, the amount of time spent on video games decreases.
There are two prominent, nationally circulated newspapers, The Wall Street Journal and USA Today. Among all libraries across the country, 45% subscribe to The Wall Street Journal and 40% subscribe to USA Today, while only 25% subscribe to both The Wall Street Journal and USA Today. If a library is selected at random, what is the probability that it subscribes to The Wall Street Journal but not USA Today?
Answer:
20% = 0.2
Step-by-step explanation:
Let A = Wall Street Journal = 45%
Let B = USA Today = 40%
Let C = Both = 25%
C = A∩B = 25%
The focus is to determine that a random library subscribes to A only
The probability of subscribing to A = 45%
However, there are subscribers to A that are also subsribed to B
This group is C = 25%
To find the probability of subscribing to A only;
Probability of A only = P{A} - P{A∩B} = P{A} - P{C}
P{A} only = 45% - 25% = 20%
P{A} only = 0.2
4) A sales associate in a department store earns a commission on each suit and each pair of shoes sold. One week, she earned $47 in commission for selling 3 suits and a pair of shoes. The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes.
a) Write a system of equations to represent the situation. Explain what your x and y will represent.
b) Solve the system of equations.
c) How much commission does she earn for selling each suit and each pair of shoes?
The sales associate earns a commission of $13 for each suit sold and $8 for each pair of shoes sold, found by solving the system of equations representing her commission earnings for two different weeks.
To represent the sales associate's commission earnings, we will use two variables: let x be the commission for each suit sold, and y be the commission for each pair of shoes sold.
(a) System of Equations:
The first week's commission can be represented by the equation 3x + y = 47. The second week's commission can be written as 7x + 2y = 107.
(b) Solving the System:
Multiply the first equation by 2 to get 6x + 2y = 94.Subtract the first modified equation from the second week's equation: (7x + 2y) - (6x + 2y) = 107 - 94.This simplifies to x = 13, meaning the commission for each suit is $13.Substitute x = 13 into the first equation: 3(13) + y = 47.Solve for y: 39 + y = 47, so y = 8.(c) The commission for each pair of shoes is $8.

Which sentence best describes the function shown?
A) The function is odd.
B) The function is even.
C) The function is symmetric about the x-axis.
D) The function is symmetric about the origin.
Answer:
B) The function is even.
Step-by-step explanation:
The function shown in the graph is ƒ(x) = |x|. This function is symmetric about the y-axis and is therefore, even.
In simple words: If you fold the picture in half then the lines should be on top of each other and become one. If this happens, then this is an even function.

What are the new coordinates of L if parallelogram LMNO is translated down 20 units?
Answer:
The answer is [tex](-4,-19)[/tex]
Step-by-step explanation:
Firstly, we have to determine the coordinates of L before the translation.
If we see the graph, we can see that the coordinate "x" is -4 and the coordinate "y" is 1. So, the original coordinates of L are [tex](4,1)[/tex]
Then, we have to determine the vector of translation. We know that the parallelogram LMNO is translated down 20 units, so it means that it moved only in the negative vertical direction. Then the coordinate of the vector is [tex](0,-20)[/tex]
Finally, in order to determine the new coordinates of L, we have to add the original coordinates of L with the coordinates of the vector of translation, that is:
[tex](-4+0,1-20)\\(-4,-19)[/tex]
So, the new coordinates of L is [tex](-4,-19)[/tex]

Lauren's scores on her math tests are 93,91,98,100,95,92,and 96. What score does Lauren need to get on her next math test test so that the mean and the mediam stay the same?
Lauren needs to get a mean/median score in order to keep from changing either of those values. She needs a 95.
_____
In order, the scores are
... 91, 92, 93, 95, 96, 98, 100
The median is the middle of these, 95, and the problem statement tells us the mean is the same (which it is).
=====
If Lauren were to get a higher score, it would raise the mean. The median would shift to halfway between 95 and 96. The score that makes the new mean be 95.5 is 99. The mean and median would be the same (again), but they wouldn't stay the same value they are now.
Likewise, if Lauren were to get a lower score, it would reduce the mean. The median would shift to halfway between 93 and 95. The score that makes the new mean be 94 is 87. The mean and median would be the same (again), but they wouldn't be the same value they are now.
If Lauren got 87, 95, or 99 on her test, her mean and median scores would be the same. They would only stay the same if she got a 95.
A savings account was opened with an initial deposit and never touched again. An account that does not meet the minimum balance requirement is charged a service fee.
Assuming the account was open with an initial deposit below the minimum amount, the current account balance, B, is equal to the product of the initial deposit, I, and the quantity of the difference of 1 and the monthly service fee, f, raised to the power of n, the number of months since the account was open.
If an initial deposit of $2,713.00 is made to the account with a monthly service fee of 5%, what will be the value of B after 13 months? Round to the nearest cent.
To find the current balance B after 13 months with an initial deposit of $2,713.00 and a 5% monthly service fee, you multiply the initial deposit by 0.95 to the power of 13, resulting in a balance of approximately $1,392.64.
Explanation:The student's question involves using a given mathematical formula to find the current balance of a savings account affected by a monthly service fee. The formula provided states that the current balance B is equal to the initial deposit I times the quantity (1 - monthly service fee f) raised to the power of the number of months n. To calculate the current balance after 13 months, given an initial deposit of $2,713.00 and a monthly service fee of 5%, you'd perform the following calculation:
Convert the percentage fee to a decimal: 5% = 0.05.Subtract the service fee from 1: 1 - 0.05 = 0.95.Raise the difference to the power of the number of months: 0.9513.Multiply the result by the initial deposit: $2,713.00 × 0.9513.Using a calculator, this gives:
B = $2,713.00 × (0.9513) ≈ $2,713.00 × 0.5133421 ≈ $1,392.64
Rounded to the nearest cent, the value of B after 13 months is $1,392.64.
