To find the cost of gas for Sally's commute, you would multiply the number of gallons she uses daily by the cost per gallon. Assuming a daily use of one gallon at $4 per gallon, Sally would spend $4 per day, $20 per week (5-day workweek), and $1,040 per year (52 workweeks). This does not account for variable factors such as days off or gas price changes.
Explanation:The student is asking about the cost of gasoline for commuting to and from a job. Since we do not have the exact distance Sally travels or the efficiency of her vehicle, we cannot compute the exact cost per day, week, or year. However, if we assume Sally uses one gallon of gas per day at a cost of $4 per gallon, here's how you calculate the costs:
Per day: Sally would spend $4 each day on gas.Per week: Assuming she works 5 days a week, Sally would spend 5 days x $4/day = $20 per week on gas.Per year: If Sally works 52 weeks a year, she would spend 52 weeks x $20/week = $1,040 per year on gas.These calculations are based on the premise of daily one-gallon gas usage and do not take into account vacations, days off, or possible fluctuations in gas prices.
what is the area of the composite figure ? enter your answer in the box . use 3.14 for pi
Answer:
The area of the composite figure = 12.785 square units
Step-by-step explanation:
The figure composite of :
A ⇒ Rectangle with coordinates (0,0) , (0,5) , (2,5) and (2,0)
B ⇒ Rectangle with coordinates (2,0) , (2,1) , (4,1) and (4.0)
C ⇒ Quarter of a circle with coordinates (2,1) , (2,2) and (3,1)

The length of a rectangle is twelve inches more than its width. The perimeter of the rectangle is 276 inches. What are the dimensions of the rectangle?
Answer: The dimensions of the rectangle are
Length = 75 and Width = 63
Step-by-step explanation: We would start with the information about the sides of the rectangle which states that the length is twelve inches more than it's width. In other words, if the width is represented by the letter w, then the length will be w + 12.
Also the perimeter of a rectangle is given as
2(L + W) where L is the length and W is the width of the rectangle
Therefore
Perimeter = 2( {w +12} + w)
276 = 2(2w + 12)
276 = 4w + 24
Subtract 24 from both sides of the equation
252 = 4w
Divide both sides of the equation by 4
63 = w
Therefore the width of the rectangle is 63 and the length is 75 (63 + 12).
L = 75 inches
W = 63 inches

11. The perimeter of a rectangle is 60 cm. The length is four times the width. What
are the length and the width of the rectangle?
Answer:
Length = 24 cm
Width = 6 cm.
Step-by-step explanation:
The formula to compute the perimeter of a rectangle is,
[tex]Perimeter=2(length+width)[/tex]
Given:
Perimeter = 60 cm
width = w
length = 4w
Determine the value of width as follows:
[tex]Perimeter=2(length+width)\\60=2\times(4w+w)\\60=10w\\w=6[/tex]
The value of length is:
[tex]length(l)=4\times w\\l=4\times6\\l=24[/tex]
Thus, the length and the width of the rectangle are 24 cm and 6 cm respectively.

The sum of two numbers is 39 and their difference is 5. Which is the larger number?
Answer:
22
Step-by-step explanation:
Let x be a number
Other number = 39 -x
x - (39 - x) =5
x - 39 + x = 5
2x = 5 + 39 = 44
x = 44/2
x = 22
Other number = 39 - 22 = 17
Answer:
The larger number = 22
Step-by-step explanation:
Let the two number x and y
The sum of two numbers is 39 can be represented as:
x + y = 39----------------1
The difference of two numbers is 5 can be represented as:
x - y = 5------------------2
x + y = 39----------------1
x - y = 5------------------2
Using Elimination Method and subtracting 2 from 1
x-x + y-(-y) = 39 - 5
0+y+y=34
2y=34
y=34/2
y=17
substituting y=17 in 1
x+17=39
x=39-17
x=22
∴ The larger number = 22
Find the pattern, then write the next two numbers.

You add 2 to the additional 2 you started with
0+2=2
2+(2x2)=6
6+(2x3)=12
The required next two-term of the sequence is 30 and 42.
Given that,
To determine the pattern and next two-term of numbers 0, 2, 6, 12, 20.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
The given sequence is,
0, 2, 6, 12, 20,
a0 = 0,
a1 = 2
nth term an = a(n - 1) + 2(n - 1)
For 6th term
n = 6
6th term = a(6 - 1) + 2(6 - 1)
a6 = a5 + 10
a6 = 20 + 10
a6 = 30
7th term,
an = a(n -1) + 2 (n - 1)
a7 = a6 + 2*6
a7 = 30 + 12
a7 = 42
Thus, the required next two-term of the sequence is 30 and 42.

What is the value of -36÷(-4/9)
The value of -36 divided by (-4/9) is 81, which is found by multiplying -36 with the reciprocal of (-4/9), giving the result 324/4, which simplifies to 81.
To find the value of -36 divided by (-4/9), you can think of division by a fraction as multiplication by its reciprocal. So, the problem changes from division to multiplication: -36 * (-9/4). To solve this:
First, multiply the numerators: -36 * -9 = 324.
Then, multiply the denominators: 1 * 4 = 4.
Now, divide 324 by 4 to get 81.
Therefore, the value of -36 divided by (-4/9) is 81.

Find the equation of a line that is parallel to line g that contains (P, Q).
the coordinate plane has a line g that passes through the points (-3,2) and (0,5).
3x − y = 3P − Q
3x + y = Q − 3P
x − y = P − Q
x + y = Q − P
Correct option:
[tex]\boxed{x-y=P-Q}[/tex]
Explanation:
Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1[/tex]
So we can write the point-slope form of the equation of the line as follows:
[tex]y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}[/tex]

Rectangle 25 feet long. It has a perimeter of 130 feet. What is the area of the basement?
Final answer:
To find the area of the basement, we started with the given perimeter of 130 feet and the known length of 25 feet and solved for the missing width. Once we determined the width was 40 feet, we used the formula for the area of a rectangle (Area = length × width) to calculate that the basement's area is 1000 square feet.
Explanation:
To solve the question regarding the area of a rectangle where the length is 25 feet and the perimeter is 130 feet, we must first deduce the width of the rectangle using the perimeter formula: P = 2l + 2w (where P is the perimeter, l is the length, and w is the width). Since we know the perimeter (P) and the length (l), we can rearrange this formula to solve for the width (w).
The perimeter formula is expressed as:
130 = 2(25) + 2w
130 = 50 + 2w
2w = 130 - 50
2w = 80
w = 40 feet
Now that we have both the length and the width, we can calculate the area of the rectangle using the formula Area = length × width.
Therefore, the area of the rectangle is:
Area = 25 feet × 40 feet
Area = 1000 square feet

Please help with question number three. Only first and third. I appreciate your help, I am lost!
I'll do the first part to get you started.
--------------------
Area = 1/2
Length = 7/8
Width = W
Area of rectangle = Length*Width
A = L*W
1/2 = (7/8)*W
(8/7)*(1/2) = (8/7)*(7/8)*W .... see note1 below
(8*1)/(7*2) = (8*7)/(7*8)*W .... see note2
8/14 = (56/56)*W
4/7 = 1*W .... see note3 and note4
W = 4/7Final Answer: 4/7--------------------
Foot notes
note1: I multiplied both sides by the reciprocal of 7/8, that way the "7/8" on the right side cancels out (as you'll see in a few steps later)note2: I used the rule (a/b)*(c/d) = (a*c)/(b*d)note3: the 56/56 turns into 1, and later on 1*W becomes just Wnote4: 8/14 reduces to 4/7 after dividing both parts by 29 pounds for $1.50 how many pounds for $1.00

A circle and a square each have a perimeter of 160 feet. Which has the greater area and by how much
Answer:
[tex]The \: circle \: has \: a \: bigger \: area \: by \approx 438 \: {ft}^{2} [/tex]
Explanation:
[tex]Diameter \: of \: circle:160 \div 3.14 \approx 51 \: ft \\ Area \: of \: circle : \frac{3.14 \times {51}^{2} }{4} \approx 2038 \: {ft}^{2} \\ Sides \: of \: square:160 \div 4 = 40 \: ft \\
Area \: of \: square: \: {40}^{2} = 1600 \: {ft}^{2} \\ 2038 - 1600\approx 438 \: {ft}^{2} [/tex]
Final answer:
Comparing the areas of a circle and a square with the same perimeter of 160 feet, the circle has a greater area by approximately 435.75 square feet.
Explanation:
We are comparing the areas of a circle and a square which both have a perimeter of 160 feet. For the square, since the perimeter (P) is 160 feet, each side (s) will be P/4, which gives us s = 40 feet. The area of the square (Asquare) is s², so Asquare = 40² = 1600 square feet.
For the circle, the perimeter is the circumference (C), which is 160 feet. The formula for the circumference of a circle is C = 2πr, where r is the radius. So, 160 = 2πr, giving us r = 160/(2π). The area of the circle (Acircle) is πr², so Acircle = π(160/(2π))². After calculation, we find that Acircle ≈ 2035.75 square feet.
Comparing the two areas, the circle has a greater area than the square by Acircle - Asquare ≈ 2035.75 - 1600 ≈ 435.75 square feet.
