Answer:
area =729 feet square
perimeter = 108 feet
Step-by-step explanation:
Given the side of a square is 9 cm.
The scale is given as :
1 cm = 3 feet
Since 1 cm represents 3 feet.
Therefore, 9 cm will represent = 9 x 3 feet
= 27 feet
So the side of the square is 27 feet.
Therefore, its area = Side x side
= 27 x 27
= 729 feet square
And the perimeter = 4 x side
= 4 x 27
= 108 feet

Identify square root of 3 as either rational or irrational, and approximate to the tenths place.
Answer:
Irrational
[tex]\sqrt{3}[/tex] = approx. 1.7
Step-by-step explanation:
The square root of 3 is irrational, because 3 is not a perfect square.
For example, 4 is a perfect square, so the square root (2) will be rational.
The square root of 3 is 1.73205080757,
and we can round this to 1.7 for the tenths place

Answer:
D
Step-by-step explanation:
The volume for a rectangular prism is given by the formula:
[tex]V=lwh[/tex]
The length is 2h, the width is 9-h, and the height is h. So:
[tex]V=2h(h)(9-h)[/tex]
Multiply the first two terms:
[tex]V=2h^2(9-h)[/tex]
Distribute:
[tex]V=18h^2-2h^3[/tex]
Our answer is D.

What is the slope of the line x=5
The slope of the line x = 5 is undefined.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation that models it is given by;
y = mx + b
x = 5
This ultimately implies that, this line is a vertical line and as such, it has no slope or an undefined slope. Therefore, the x-intercept is 5 and the slope is undefined.

Ruby, her brother, and 3 friends will share the bag of candy she bought. There are 110 candies in the bag. How many will each person get? A. 22 B. 24 C. 26
Answer: A
Step-by-step explanation: since there’s 110 candies divide it between the 3 friends plus ruby and her brother. So divide 110 by 5 and it will be your final answer
Answer:
A. 22
Step-by-step explanation:
First, you don't want to fall into the trap. The question says Ruby, her brother, AND 3 friends. That means you have to add everyone. 3(friends)+2(Ruby and her brother)=5 people. Then you have to divide. 110/5=22.
So, A.22 candies each.

What is the inverse relation of the function whose equation
is y = 3x – 2?
oy = x
o y = 3x + 2
o y = 2x - 3
x + 2
y =
3
Answer:
The inverse of the function is;
x = (y + 2)/3
Step-by-step explanation:
Here in this question, we shall be calculating the inverse of a function.
The function is;
y = 3x - 2
Firstly, let w = x;
y = 3w -2
y + 2 = 3w
w = (y + 2)/3
Now replace w by x
x = (y + 2)/3
This is the inverse of the function
Solve for the variable. Show all work. |6x| - 8 = -8
Answer:
x = 0
Step-by-step explanation:
|6x| - 8 = -8
Add 8 to each side
|6x| - 8+8 = -8+8
|6x| = 0
Removing the absolute value
6x = 0
Divide by 6
6x/6 = 0/6
x = 0
Solve for x.
8x = 42 - 32
O x = 8
O x = 4
O r=-4
O = -8
Johnny is saving money to buy a PS 5. He already has $30 in the bank and gets $10 per week allowance for doing his chores. Write an equation to to find the number of weeks, x, it will take him to have $600.
Answer:
10x + 30 = 600
Step-by-step explanation:
Johnny gets $10 per week, which is $10x for x number of weeks.
He already has $30, so his money becomes 10x + 30.
His goal is to have $600, so our equation becomes 10x + 30 = 600

It takes billy 6 minutes to walk 1.5 km. How long will it take billy to walk 9km?
Answer:
It will take Billy 36 minutes to walk 9km.
Answer:
[tex]\boxed{\tt 36 \ minutes}[/tex]
Step-by-step explanation:
Let's make a proportion using the following setup:
[tex]\frac{minutes}{kilometers} =\frac{minutes}{kilometers} \\[/tex]
We know it takes Billy 6 minutes to walk 1.5 kilometers.
[tex]\frac{6\ minutes}{1.5\ kilometers} =\frac{minutes}{kilometers}[/tex]
We don't know how long it takes him to walk 9 kilometers, so we can say it takes him x minutes to walk 9 kilometers.
[tex]\frac{6\ minutes}{1.5\ kilometers} =\frac{x\ minutes}{9\ kilometers}[/tex]
[tex]\frac{6}{1.5} =\frac{x}{9}[/tex]
Now, solve for x. To do this, isolate x on one side of the proportion. x is being divided by 9. The inverse of division is multiplication. Multiply both sides of the proportion by 9.
[tex]9*\frac{6}{1.5} =\frac{x}{9}*9[/tex]
[tex]9*\frac{6}{1.5} =x[/tex]
[tex]9*4=x[/tex]
[tex]36=x[/tex]
x= 36 minutes
It will take Billy 36 minutes to walk 9 kilometers.

Find the equation of a line that is perpendicular to the line y = 1/9x +6 and contains the point (-7,0).
Answer:
y = -9x - 42Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
Given line:
y = 1/9x + 6Perpendicular line is:
y = - 9x + b and passes through the point (-7, 0)0 = -9*(-7) + bb = - 42So the line is:
y = -9x - 42Find the product. (-10) (-10) (-10)

the answer is -1000 as -10 cube is -1000
The value of product of (-10)(-10)(-10) is -1000.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts right-hand operand from left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
To determine the product of (-10)(-10)(-10)
⇒ (-10)(-10)(-10)
Multiplying the last two terms and (-) signs cancel out each other,
⇒ (-10)(100)
Multiplying the two terms,
⇒ -1000
Hence, the value of product of (-10)(-10)(-10) is -1000.

Which of the following polynomial functions is graphed below
Answer:
A, the other person was correct
Step-by-step explanation:
The polynomial functions is graphed below is f(x) = (x+ 4)(x- 2)².
What is Function?a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).
There are three components that make up a function: a set of inputs, a set of outputs, and a rule that links the elements of the input set to the elements of the output set so that each input is paired with exactly one output.
We have a graph for polynomial function.
We know that the function of graph have solution where the graph touches or passes the x axis.
Here from the graph at x = -4 and at x= 2 the touches and moves upward.
So, the factors of polynomial are (x+ 4) and (x- 2).
Thus, the polynomial function is f(x) = (x+ 4)(x- 2)².
