Answer:
4.5
Step-by-step explanation:
Answer:
4.5. Since you‘re dividing x by 4.5, multiply it by 4.5 to cancel the 4.5. Do the same with the other side.

2. The volume of a cylinder varies jointly with its height and the square of the radius. A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. Another spice container is 3 inches tall with a radius of 1.5 inches, what would be the volume?
Answer:
Volume=21.195 cubic inch
Step-by-step explanation:
The volume of a cylinder varies jointly with its height and the square of the radius is expressed as
V∝hr^2
Introducing our constant of proportionality,K we have that
V =Khr^2
Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that
V =Khr^2
7.85=K 2.5 X 1^2
K=7.85/2.5 x1
K=3.14
Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?
V =Khr^2
V=3.14 X 3 X 1.5^2
V=21.195 cubic inch
Write an equation for the amount of money, , that will be collected if boxes of chocolate bars are sold. Which is the independent variable and which is the dependent variable
Answer:
Kindly check explanation
Step-by-step explanation:
Let amount of money = C
If the number of chocolate bars sold = x
Let cost per chocolate bar = p, since cost per bar isn't stated
Amount of money that will be collected :
C(x) = P * x
The dependent variable is the Amount of money that will be collected as the amount of money depends on the number of chockate bars sold
The number of chocolate bars sold us the independent variable as it dictates the amout of money to be collected, hence it is the predictor variable.
Find the distance between (2, 9) & (-1, 4). Round to the nearest tenth.
Answer:
1.7
Step-by-step explanation:
To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].
y2 = 4, y1 = 9, x2 = -1, x1 = 2
Insert the values into the equation:
[tex]\frac{4-9}{-1-2}[/tex]
Simplify:
[tex]\frac{4-9}{-1-2}= \frac{-5}{-3}=\frac{5}{3}[/tex][tex]\frac{}{} =1.7[/tex]
The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.

Evaluate 4b-a when a=12 and b=7
Answer:
4b - a = 15
Step-by-step explanation:
if you replace the variables with their equivalent counterparts you get the equation 4(7) - 12 = __ when you do the math make sure to do the parentheses first then subtract, just like in elementary school remember pemdas parentheses, exponents, multiplication, division, addition, subtraction. I hope this helps.
good luck:)

Answer: X is less than or equal to 7 (keep the inequality sign you already have)
Step-by-step explanation:
Subtract 11 from 18
18-11 = 7
X is less than or equal to 7
Answer:
OMG i am doing this is school to!! So anyways 11+x< or equal to 18=0.611.
Step-by-step explanation:
Simplify 11/x. Then it should be 11/x-18=0.

Answer:
3/x^14
Step-by-step explanation:
Answer:
3x⁻¹⁴ or 3/x¹⁴Step-by-step explanation:
12(x⁻⁴)² / 4(x⁻²)⁻³ =12/4 × x⁻⁸/x⁶ =3x⁻⁸⁻⁶ =3x⁻¹⁴ or 3/x¹⁴Are the equations m + 3 = -5 and m = -2 equivalent? Explain why or why not?
Answer:
Step-by-step explanation:
When m+3=-5, collection of like terms says; -5-3
Now,-5+-3 = -8 and -2≠-8 hence,they aren't equivalent
Find the mean
13, 10, 10, 17, 10
Answer:
12 is your answer
Step-by-step explanation:
Heres how to find it:
How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
13+10+10+17+10=60
60/5=12
12

Clayton needs to reflect the triangle below across the line y = x.
On a coordinate plane, triangle A B C has points (5.5, 7), (6, 2), (4, 4).
Which statements about the reflection are true? Check all that apply.
Clayton could use the relationship (x, y) right-arrow (y, x) to find the points of the image.
Clayton could negate both the x and y values in the points to find the points of the image.
C’ will remain in the same location as C because it is on the line of reflection.
C’ will move because all points move in a reflection.
The image and the pre-image will be congruent triangles.
The image and pre-image will not have the same orientation because reflections flip figures.
Answer:
A. Clayton could use the relationship (x,y)\rightarrow (y,x)(x,y)→(y,x) to find the points of the image.
C. C’ will remain in the same location as C because it is on the line of reflection.
D. The image and the pre-image will be congruent triangles.
Step-by-step explanation:
A. Clayton could use the relationship (x,y)\rightarrow (y,x)(x,y)→(y,x) to find the points of the image.
This option is TRUE. When we reflect a shape in the line y=xy=x , we just have to swap the x and y coordinates.
B. .Clayton could negate both the x and y values in the points to find the points of the image.
False; This is a rotation of 180\degree180° about the origin.
C. C’ will remain in the same location as C because it is on the line of reflection.
This statement is True
C’ will move because all points move in a reflection.
This statement is false because,C(2,2) and C'(2,2) will have the same coordinate.
D. The image and the pre-image will be congruent triangles.
This is TRUE because reflection is a shape preserving transformation(rigid motion).
E. The image and pre-image will not have the same orientation because reflections flip figures.
This is False
Hope this helps :)
