Write 23/12 as a mixed number.
Hey there!
23/12
= 23/1 ÷ 12/1
= 23/1 × 1/12
= 23(1) × 1(12)
= 23/12
≈ 1 11/12
Those steps above are somewhat easier to solving your given equation!
Anyways, your answer is: 1 11/12
Good luck on your assignment & enjoy your day!

i need help with #7 c and d
Answer:
c. 33.0%
d. 14.5%
Step-by-step explanation:
For answering questions about percentages in different categories or combinations of categories, it is convenient to find the totals of rows and columns in the table. These totals are shown in the attached.
__
c.Students who surf total 32+65 = 97. Of those, 32 also skateboard. The requested percentage is ...
32/97 × 100% ≈ 33.0% . . . . surfers who also skateboard
__
d.The total number of students is 166. Of those, the number who neither surf nor skateboard is 24. That percentage is ...
24/166 × 100% ≈ 14.5% . . . . students who don't surf or skateboard
_____
Additional comment
a. 97/166 ≈ 58.4% surf
b. 89/166 ≈ 53.6% do not skateboard
__
This sort of table is called a "two-way table." One set of categories is represented in rows, another set is represented in columns. This table is filled with frequencies. Such tables can also display relative frequencies by dividing the entire table by the total of totals in the lower right corner.
To which family does the function y = (x 2) superscript one-half baseline 3 belong? quadratic square root exponential reciprocal
The function y = √(x + 2) + 3 is a quadratic function. Then the correct optin is A.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given below.
[tex]y = (x+2)^{1/2} + 3[/tex]
The equation can be written as
[tex]y - 3= (x+2)^{1/2}[/tex]
Square on both sides, we have
[tex]\begin{aligned} (y - 3)^2 &= [(x+2)^{1/2}]^2 \\\\x + 2 &= y^2 + 9 -6y \\\\x &= y^2 -6y +7 \end{aligned}[/tex]
The equation is a quadratic equation.

omg please help its due by 12 am! the sum of 2 numbers is 69. the larger number is 3 less than twice the smaller number .find the numbers. show your work!
Answer:
x = 45, y = 24.
Step-by-step explanation:
If the 2 numbers are x and y:
x + y = 69...........(1)
x = 2y - 3
x - 2y = -3...........(2)
Subtract: (1) - (2):
x - x + y - (-2y) = 69 - (-3)
y + 2y = 72
3y = 72
y = 24.
From equation 1:-
x + 24 = 69
x = 45.
Answer:
one number would be 63 and the other would be 6
Step-by-step explanation:
69/2=34.5
it says 3 less which means minus 3, so you would:
34.5-3=31.5
then it says twice the smaller number, so you would:
31.5*2

19x+28=20x-53
Answer:
x = 81
Step-by-step explanation:
Given:
[tex]\displaystyle \large{19x+28=20x-53}[/tex]
Subtract both sides by 28:
[tex]\displaystyle \large{19x+28-28=20x-53-28}\\\displaystyle \large{19x=20x-81}[/tex]
Subtract both sides by 19x:
[tex]\displaystyle \large{19x-19x=20x-81-19x}\\\displaystyle \large{0=x-81}[/tex]
Add both sides by 81:
[tex]\displaystyle \large{0+81=x-81+81}\\\displaystyle \large{81=x}\\\displaystyle \large{\therefore x=81}[/tex]
Therefore, the solution is x = 81

Answer:
1. E: 20a - 18
2. D: 42

4. I: 105
CODE: EDGI
Step-by-step explanation:
Question 1
Perimeter of a rectangle = 2W + 2L
(where W is the width and L is the length)
Given:
width = 2a + 3length = 8a - 12Perimeter = 2(2a + 3) + 2(8a - 12)
= 4a + 6 + 16a - 24
= 20a - 18
Question 2
When a = 3
⇒ perimeter = 20(3) -18
= 60 - 18
= 42 centimeters
Question 3
The dashes on the side lengths mean those sides are equal in length.
⇒ perimeter = (7b - 2) + (7b - 2) + (3b + 7)
= 17b + 3
Question 4
When b = 6
⇒ perimeter = 17(6) + 3
= 102 + 3
= 105 meters

what is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line represented by 8x + 3y =15?

What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the line is parallel to 8x + 3y =15, hence the slope is given by:
[tex]m = -\frac{8}{3}[/tex]
It passes through the point (6, -1), hence:
y = mx + b
[tex]-1 = -\frac{8}{3} \times 6 + b[/tex]
b = 15
Hence:
[tex]y = -\frac{8}{3}x + 15[/tex]
In standard form:
[tex]\frac{8}{3}x + y = 15[/tex]

A cylinder has a radius of 19 millimeters. Its volume is 22,670.8 cubic millimeters. What is the height of the cylinder?
Answer:
19.99
Step-by-step explanation:
use the formula
[tex]\pi {r}^{2} h = v[/tex]
change it up so that you solve for height
[tex] \frac{v}{ {r}^{2} \times \pi } = h[/tex]
substitute values in and solve
Answer:
20.00 mm to the nearest hundredth.
Step-by-step explanation:
V = π r^2 h
22,670.8 = π * 19^2 * h
h = 22,670.8 / π * 19^2
= 22,670.8 / 1134.115
