Answer:
2 1/2
Step-by-step explanation:
Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.
4 3/4
4 * 4 + 3 = 19
19/4
2 1/4
2 * 4 + 1 = 9
9/4
Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.
19/4 - 9/4 = 10/4
Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:
4 * 2 = 8
10 - 8 = 2

Find the mode of the data
Answer:
shoe size (US) 6
Step-by-step explanation:
Mode = most frequently occurring data value
From inspection of the table, we can see that the highest frequency (most number of women) is 20, so therefore the modal class of the data is shoe size (US) 6.
Answer:
Shoe Size (US) = 6Step-by-step explanation:
The mode of the data is the modal class with the highest frequencyIt is 20, present in the 4th columnIts corresponds with the modal class : Shoe Size (US) = 6How to solve 16x-8y=72
**Kind note:
Since there are two variables in one equation, it is impossible to determine a specific value for x and y. (Unless the trial-and-error method is used).
How to determine the value of x using the equation (16x - 8y = 72)?
To determine the value of "x", we need to isolate the x-variable on one side. The value (or expression) obtained on the opposite side of the x-variable will be the value of x.
How to determine the value of y using the equation (16x - 8y = 72)?
To determine the value of "y", we need to isolate the y-variable on one side. The value (or expression) obtained on the opposite side of the y-variable will be the value of y.
Determining the x-variable:
⇒ 16x - 8y = 72
⇒ 16x = 72 + 8y [Adding 8y to both sides of the equation]
⇒ 16x/16 = (72 + 8y)/16 [Dividing 16 to both sides of the equation]
⇒ x = 9/2 + y/2 [Simplifying both sides of the equation]
⇒ x = (9 + y)/2 [Combining the denominators]
Determining the y-variable:
⇒ 16x - 8y = 72
⇒ 16x - 8y - 16x = 72 - 16x [Subtracting 16x both sides of the equation]
⇒ -8y = 72 - 16x [Simplifying both sides of the equation]
⇒ -8y/-8 = (72 - 16x)/-8 [Dividing -8 to both sides of the equation]
⇒ -8y/-8 = 72/-8 - 16x/-8
⇒ -8y/-8 = -72/8 + 16x/8
⇒ y = -9 + 2x [Simplifying both sides of the equation]
First simplify it to suitable form of slope intercept then you can get values
16x-8y=722x-y=9y=2x-9The pairs are
(1,-7)(2,-5)(3,-3)(4,-1)(5,1)And so on

The circumference of a circle is 18π ft. What is the area, in square feet? Express your answer in terms of \piπ.
HELp pls
Answer:
A = 81 pi ft^2
Step-by-step explanation:
We know the circumference of a circle is given by
C = 2 * pi *r
18 pi = 2 * pi *r
Divide each side by 2 pi
18 pi / ( 2pi) = 2 pi r / ( 2pi)
9 = r
We can find the area by
A = pi r^2
A = pi ( 9)^2
A = 81 pi ft^2

$3.50 per mile
$10.00 per mile
$4.50 per mile
$8.00 per mile
Answer:
$3.50 per mile
Step-by-step explanation:
Slope-intercept form of a linear equation: [tex]y=mx+b[/tex]
(where m is the slope and b is the y-intercept)
Given linear equation: [tex]y=3.5x+4.5[/tex]
(where x is the number of miles traveled and y is the total cost)
The rate of change is the slope of the linear equation.
Therefore, the rate of change is $3.50 per mile.
Compare to slope intercept form of line
Slope=m=3.5Now
Rate of change=slope

Answer:
(2, -7)
x = 2
y = -7
Step-by-step explanation:
Let's solve this system of equations by elimination.
Start by multiplying the first equation by 2:
[tex]2(4x)+2(3y)=2(-13)\\8x+6y=-26[/tex]
Next, multiply the second equation by 3:
[tex]3(-5x)+3(2y)=3(-24)\\-15x+6y=-72[/tex]
Notice that both equations now have a "6y", meaning we can subtract both equations and thereby eliminating the variable "y" from the equation:
[tex]8x+6y-(-15x+6y)=-26-(-72)\\8x+6y+15x-6y=-26+72\\23x=46[/tex]
Divide both sides by 23
[tex]x=2[/tex]
Substitute 2 for "x" to solve for "y".
[tex]4x+3y=-13\\4(2)+3y=-13\\8+3y=-13[/tex]
Subtract 8 from both sides:
[tex]3y=-21[/tex]
Divide both sides by 3:
[tex]y=-7[/tex]
Therefore the answer is:
[tex](x, y)=(2, -7)[/tex]
Additional Comments:
Note that we can only divide, subtract, multiply, or add both sides of the equation by the same quantity due to the Division, Subtraction, Multiplication, or Addition Property of Equality. These properties state that if you divide/subtract/multiply/add one side of the equation by one quantity, you must do the same to the other side of the equation so that it remains an equation.
A wall in Alex and Carla Dinu's garden is to be built using brick that is 5 3/8 inches wide and a mortar joint that is 3/4
inch wide. Using the diagram, what is the height of the wall?
Answer: 29 7/8
Step-by-step explanation:
The height of wall will be 29.875 inch.
How to measure height of the wall?The height of the wall can be measured by the sum of total height of bricks and the height of mortar joint between the bricks.
According to question there is 4 mortar joint and 5 rows of bricks.
How to determine the no. of mortar joint?1 mortar joint is situated between 2 bricks. So, if the no. of bricks is n, then mortar joint between them will be n-1.
So, width of one mortar joint is= 3/4 inch
Width of 4 mortar joints = (3/4)*4=3 inch
width of one brick is= 5.375 inch
Width of 5 bricks = 5.375*5=26.875 inch
Height of the wall
= width of 4 mortar joints + width of 5 bricks
= 3+26.875
=29.875inch or 29 7/8 inch
Therefore, the height of wall will be 29.875 inch.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Tristan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged him $50 for parts.
The cost for labor per hour is,
TC = 50 + 4.75x
643.75 = 50 + 4.75x

Step-by-step explanation:

= 2/7 * 1.4 x^3 - 2/7 *3.5xy
= 0.4x^3 - xy
The expression 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.
What is a polynomial?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
To write 2/7x(1.4x² - 3.5y) as a polynomial, we need to first simplify the expression inside the parentheses by distributing the 2/7x:
2/7x(1.4x² - 3.5y) = (2/7x)(1.4x²) - (2/7x)(3.5y)
Next, we can simplify each term by multiplying the coefficients:
2/7x(1.4x² - 3.5y) = (4/5)x³ - (10/7)xy
Thus, 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.
