Answer:
1200 square inches
Step-by-step explanation:
First find area of rectangle which is length x width
20 x 30 = 600
then to find area of the two right triangles multiply the legs then divide by 2
20 x 30 = 600
600/2 = 300
since there is 2 multiply 300 by 2
600
then add everything together
600+600 = 1200

Does the table below represent a function?
A table titled 'Car Wash Grand Opening' is shown. The first column, 'Time comma x left parenthesis minutes right parenthesis' contains the values 0 through 3 in order top to bottom. The second column 'Water comma y left parenthesis gallons right parenthesis' has the values 440, 428, 416, and 404 listed top to bottom.
A. yes
B. no
I will mark brainliest for step by step process and correct solution. Thanks! Need this ASAP!
Answer:
a) Yes.
Step-by-step explanation:
A function does not have any repeating values for a given x-value. According to the values of the table, there aren't multiple y-values for a given x-value. Therefore, the table represents a function.

Answer:
42.1 cm
Step-by-step explanation:
θ = 265°
Radius (r) = 9.1 cm
Arc length of major arc GH = θ/360 × 2πr
Plug in the values into the equation
Length of arc GH = 265/360 × 2 × π × 9.1
= 42.0886149
= 42.1 cm (nearest tenth)

The ratio of two numbers is 8: 5. Their sum is 91. What is the
greater number?
Answer:
Step-by-step explanation:
a:b = 8:5
a = 8x, b= 5x
a+b = 91
13x = 91
x = 7
a=8x = 56
b = 5x = 35
The larger number is 56

y = -2x + 3
in the equation y = mx + b, the m represents the slope and b represents the y-intercept
remember that slope is rise over run:
starting from the point (1, 1) you rise 2 up and go over left 1 to reach the second point shown (0, 3).
add a negative sign to show the negative downward slope, and the m in the equation would be -2
the y-intercept is just where the line hits the y-axis, or when the x in the ordered pair is 0. In this graph, one of the points given is (0, 3) so 3 is the y intercept
just plug all that into y = mx + b
m, the slope, is -2 and b, the y- intercept, is 3.
y = -2x + 3 is your answer
Find the gradient of the line segment between the points (3,2) and (2,5).

The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what speeds are the two trains traveling?
Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10
= 58

Placed the following quadratic in vertex form by completing the square and then state the coordinates of its vertex?
Y=x^2+18x-12
Answer:
y = (x + 9)² -93
vertex: (-9, -93)
Step-by-step explanation:
x² + 18x = 12
x² + 18x + 81 = 12 + 81
(x+9)² = 93
y = (x + 9)² -93
vertex: (-9, -93)

Pyhthagoras Theorem :-
=> h² = (2x)² + (11x)²

=> h = 5√5 x

Answer:
Number of hours she worked so far = 15 hours
Step-by-step explanation:
Total hours scheduled to work this week = 20 hours
Percentage of Hours worked so far = 75%
How many hours has she worked so far this week?
Number of hours she worked so far = 75% of 20 hours
= 75/100 * 20
= 0.75 * 20
= 15
Number of hours she worked so far = 15 hours
If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)

Which of the following functions is equivalent to the function below?
Select three that apply.
f(x)=(13)2x
g(x)=(23)−x
g(x)=9−x
g(x)=3x2
g(x)=(16)x
g(x)=(19)x
g(x)=3−2x
Answer:
g(x) = 3x2
g(x) = 16x
g(x) = 19x
Explanation:
Assuming that you're referring to f(x) = (13)2x, without much context, I'm going to assume that any of the ax + b, are going to be wrong. The the process of elimination, the only ones left are just x and a coefficient.

Ann runs a day care center. Of the last 18 children to enroll at the day care center, 8 of them have been elementary school students. Considering this data, how many of the next 9 children to enroll should you expect to be elementary school students?
We would expect that 4 of the next 9 children to enroll will be elementary school students.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.
Addition and subtraction of two matrices can be done if they have the same dimensions. This is done by simply adding or subtracting the corresponding entries in matrices.
