A pair of shoes cost 102.23
Arithmetic: Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. The basic operations of math are addition, subtraction, multiplication and division. Also called higher arithmetic, theoretical arithmetic.
Cost of 3 pairs of shoes and a dress = 352.50
Cost of dress = 45.50
Cost of 3 pairs of shoes = Cost of 3 pairs of shoes and a dress - the cost of dress = 352.20 - 45.50
= 306.7
So, the cost of each pair of shoes will be = Cost of 3 pairs of shoes/Number of pairs bought
= 306.7/3
= 102.23

At one point on the trip, the miles are recorded as 15,121 when the gas tank is
75% full. Use a ratio equation to determine the miles per gallon the sedan
averages. Round your answer to the nearest whole number.
The sedan gets 1090 miles per gallon on average, according to the ratio equation.
What exactly is a ratio?A ratio is an ordered pair of numbers a and b, denoted by the a / b, where b is not equal to zero.
What is a ratio example?If there are eight oranges and six lemons in a bowl of fruit, the orange-to-lemon ratio is eight to six.
Given: When the gas tank is 75% full, the mileage is recorded as 15,121.
A sedan tank is typically 18.5 gallons in size. So it holds 13.875 gallons of gas if it is 75% full. If it traveled 15,121 miles, the mileage per gallon is 1090, rounded to the nearest whole number.
The calculation of miles per gallon using the ratio equation:
Let, x = miles per gallon
15121:13.875 is the ratio.
x/1= 15121/13.875
13.875x = 15121
x = 15121/13.875
x = 1089.80, which equates to 1090 miles per gallon
As a result, the ratio equation used to calculate the sedan's miles per gallon averages 1090 miles per gallon.

The value of y is directly proportional to the value of x. When x=3.5, the value of y is 14. What is the value of y when x = 28? Record your answer
For x = 28, the value of [y] such that [x] is directly proportional to [y] will be 112.
What is direct proportionality?Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -
y = kx
k = y/x
where [k] is the constant
Given is the value of [y], which is directly proportional to the value of [x], and when [x] = 3.5, the value of [y] is 14.
We have the following data -
[y] = 14 at [x] = 3.5
Now, since [y] is directly proportional to [x], we cam write -
y = kx
k = y/x
k = 14/3.5. [1]
Now, for x = 28, we can write the relation as -
y/x = k
k = y/28 [2]
Now, equating equation [1] and [2], we get -
14/3.5 = y/28
y = (14 x 28)/3.5
y = (140 x 28)/35
y = (140 x 4)/5
y = 28 x 4
y = 112
Therefore, for x = 28, the value of [y] such that [x] is directly proportional to [y] will be 112.

if you placed $5 into an account that paid interest at a rate of 5%, and compounded interest yearly, how much would that account be worth in 100 years
After adding interest the sum would be worth $657.51 .
Interest is the amount paid over and above the original amount to a lender or depositor by a borrower or deposit-taking financial institution at a predetermined rate in the domains of finance and economics (the amount borrowed).
Interest differs from any fees the borrower may be required to pay to the lender or another party.interest also contrasts from a dividend, which is cash distributed to shareholders (owners) by a corporation from its profit or reserve, but not at a predefined rate or proportionally; rather, it is a portion of the reward or interest gained by risk-taking businessmen when revenue is made that surpasses all expenditures.Interest when the principal is $5 , time is 100 years and rate is 5%.
We know that from compound interest:
Amount = principal (1 + rate)ⁿ
Therefore
Amount = 5 (1 +0.05)¹⁰⁰
Amount = $657.5062...
Amount ≈ $657.51
Therefore adding interest the sum would be worth $657.51

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3y-2x= -9
y=2/3x-3 that is the slope intercept form
can someone pls explain to me how to find y intercept
Answer:
(0, -5)
Explanation:
The function is represented by f(x), and the line graphed would be y= f(x). In slope-intercept form, the equation of a line is given by y= mx +c, where m is the slope and c is the y-intercept.
Since we know that the line is linear, any two points along the line would give us the same slope value. Since y-intercepts occur at x= 0, let the y-intercept be (0, y).
[tex]\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
Slope between (-3, 1) and (1, -7)= slope between (-3, 1) and (0, y)
[tex] \frac{1 - ( -7 )}{ - 3 - 1} = \frac{y - 1}{0 - ( - 3)} [/tex]
[tex] \frac{1 + 7}{ - 4} = \frac{y - 1}{0 + 3} [/tex]
[tex] \frac{8}{ - 4} = \frac{y - 1}{3} [/tex]
[tex] - 2 = \frac{y - 1}{3} [/tex]
Multiply both sides by 3:
-2(3)= y- 1
-6= y -1
Add 1 to both sides:
y= -6 +1
y= -5
Thus, the y-intercept is (0, -5).
__________
Based on the image, however, we are to find the equation of the linear function in slope-intercept form.
The first step would be to find the slope between any two points, which would be -2. This is found using the slope formula, and we have calculated it above.
Substitute the value of the slope into y= mx +c:
y= -2x +c
The y-intercept can be found by substituting a pair of coordinates the line passes through.
When x= -3, y= 1,
1= -2(-3) +c
1= 6 +c
c= 1 -6
c= 5
Thus, the equation of the line is y= -2x +5.

The intercept is 5 because that is where the graph cuts the y axis.
PLEASE MARK AS BRAINLIEST IF YOU FOUND IT HELPFUL BECAUSE IT MAKES ME FEEL GOOD!
Step-by-step explanation:
Linear Standard Formy = mx + c;
The m equals the change in y divided by the change in x. If you choose left to right for y then you must do the same for x as well.
Δy = ( - 7 ) - ( - 15 ); Δx = 1 - 5;
Δy = - 7 + 15;
Δy = 8;
Δx = - 4;
m = 8 / - 4;
m = - 2;
y = - 2x + c;
Point SubstitutionPick a point (x, y) and sub it into the equation. Make sure to use brackets when subbing.
- 7 = - 2( 1 ) + c;
- 7 = - 2 + c;
Add 2 to both sides.
- 7 + 2 = - 2 + 2 + c;
- 5 = c;
c = - 5;
The c is the intercept.
y = - 2x - 5

A recipe of chicken marinade says mix 3 parts with oil with 2 parts soy sauce and 1 part orange juice if you need 42 cups of marinade in all how much of each ingredient should you use
Answer:
21 cups oil
14 cups soy sauce
7 cups orange juice
Step-by-step explanation:
Use 1 cup for 1 part. The original recipe as given with its small amounts would make a total of 3 + 2 + 1 = 6 parts, or 6 cups of sauce.
You want to make 42 cups.
42/6 = 7

Find WI if IE = 3
EW and YG are medians of AXYW
Based on the median and the centroid theorem, the length of WI is 6 units.
What is the Median of a Triangle?The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.
According to the centroid theorem, since J is the centroid of triangle XYW, then:
the length of IE is 1/3 of the length of segment EW.
Thus, the equation that relates the length of the segments is;
IE = 1/3(EW)
Given that:
IE = 3 units
Now Substitute the value of IE into the equation:
3 = 1/3(EW)
3(3) = EW
9 = EW
EW = 9 units
Therefore:
The Length of WI = the length of EW - the length of IE
Substitute;
Length of WI = 9 - 3
Length of WI = 6 units.

there are two aircraft carriers, a and b, and carrier a is longer in length than the carrier b. the total length of these two carriers is feet, while the difference of their lengths is only feet.
there are two aircraft carriers, a and b, and carrier a is longer in length than the carrier b. then Carrier A is 2,104 feet and Carrier B is 2,094 feet.
Since there are two aircraft carriers, A and B, and carrier A is longer in length than the carrier B, and the total length of these two carriers is 4198 feet, while the difference of their lengths is only 10 feet, to determine the length of each aircraft carrier, the following calculation must be performed:

4.188 / 2 = X
2,094 = X
2,094 + 10 = 2,104
2,094 + 2,104 = 4,198
