Answer:
V= π ⋅ 4y^2 ⋅ 9x
Step-by-step explanation:
Put the variables from the picture into the equation
r=4y
h=9x
(^2 means squared)
12 (x + 3) = 4 (2x + 9) +4x
is there a solution?????
Answer:
there is no solution
Step-by-step explanation:
You would use distributive property first to get
12x+36 = 8x+36 + 4x
by combining like terms, you would get 12x+36 = 12x+36, meaning there is no solution to this equation

One card from a deck of cards Is selected, it's is replaced, and another card is chosen. What is the probability that the first card is a red card and the second is a diamond
Answer:
1/ 8
Step-by-step explanation:
Given that:
Number of red cards in deck = 26
Number of diamonds in deck = 13
Number of cards in deck = 52
Recall :
Probability = required outcome / Total possible outcomes
Probability of choosing a red :
P(red) = 26 / 52 = 1/2
With replacement :
Probability of diamond :
P(diamond) = 13 / 52 = 1/4
Hence,
Probability of first card red, then second card diamond equals
P(red) * P(diamond)
1/2 * 1/4
= 1/8

The measure of an angle is 8 degrees less than three times the measure of another angle. If the two angles are supplementary (two angles whose sum is 180) what is the measure of the larger angle?
Answer:
The measure of the larger is [tex]133^{\circ}[/tex].
Step-by-step explanation:
Given:
The measure of an angle is [tex]8[/tex] degrees less than three times the measure of another angle.
The two angles are supplementary.
To find: The measure of the larger angle.
Solution:
Let the measure of the smaller angle be [tex]x^{\circ}[/tex].
Then the measure of the larger angle be [tex]3x^{\circ}-8^{\circ}[/tex].
The two angles are supplementary, so their sum is [tex]180^{\circ}[/tex].
So, [tex]x^{\circ}+3x^{\circ}-8^{\circ}=180^{\circ}[/tex]
[tex]\Rightarrow 4x^{\circ}-8^{\circ}=180^{\circ}[/tex]
[tex]\Rightarrow 4x^{\circ}=180^{\circ}+8^{\circ}[/tex]
[tex]\Rightarrow 4x^{\circ}=188^{\circ}[/tex]
[tex]\Rightarrow x^{\circ}=\frac{188^{\circ}}{4}[/tex]
[tex]\Rightarrow x^{\circ}=47^{\circ}[/tex]
So, the measure of the smaller angle is [tex]47^{\circ}[/tex].
And, the measure of the larger angle is [tex]3\times47^{\circ}-8^{\circ}=133^{\circ}[/tex].
Hence, the measure of the larger is [tex]133^{\circ}[/tex].

A glass is į full. Then 75cm of orange juice is poured in.
The glass is now å full. What is the total volume of the glass?
Answer:
180 cm³
Step-by-step explanation:
A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?
Let
x = total volume of the glass
1/3x + 75 = 3/4x
75 = 3/4x - 1/3x
75 = 9x-4x/12
75 = 5/12x
x = 75 ÷ 5/12
x = 75 × 12/5
= 900/5
= 180 cm³
x = 180 cm³
Select the line segment Please helppppp !!!!
Answer:
C.
Step-by-step explanation:
A line is straight, and a segment is a part of a line.
A and D and lines because they have the arrows on the side, meaning they keep going and are not a segment.
B is not a line, it curves.
So that leaves C to be the answer because it is the only straight one with no arrows.

Identify the slope and the y-intercept of the following line!
y=-3+x
Answer:
( 0 , - 3 )
Step-by-step explanation:
Answer:
1.000
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(-3+x)=0
STEP1:
Equation of a Straight Line
1.1 Solve y-x+3 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on a Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y-axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-x+3 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000
y-intercept = -3/1 = -3.00000
Calculate the X-Intercept :
When y = 0 the value of x is 3/1 Our line therefore "cuts" the x-axis at x= 3.00000
x-intercept = 3/1 = 3.00000
Calculate the Slope :
The slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -3.000 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - (-3.000) = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2.000/2.000 = 1.000
Geometric figure: Straight Line
Slope = 2.000/2.000 = 1.000
x-intercept = 3/1 = 3.00000
y-intercept = -3/1 = -3.00000
Hope this helps!

The measures of two complementary angles
are in the ratio 7:3. What is the measure of the
smaller angle? What is the measure of the
larger angle?
If the measures of two complementary angles are in the ratio 7:3. The measure of the smaller and larger angle will be 27.02 and 62.9 respectively.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
It is given that, The measures of two complementary angles are in the ratio 7:3.
The angle is referred to as be complimentary angle when the total of two angles is 90 degrees. For instance, the angles of 30 degrees and 60 degrees complement one another.
Suppose the smaller angle is x and the larger angle is y,
x+y=90 -------(1)
If the measures of two complementary angles are in the ratio of 7:3.
y:x=7:3
7x=3y
y=7/3x
Substitute the value of y in equation 1 as
x+2.333x=90
3.333x=90
x=90/3.33
x=27.02
The measure of the smaller angle is 27.02. The measure of a larger angle is obtained as,
y=90-x
y=90-27.02
y=62.9
Thus, if the measures of two complementary angles are in the ratio 7:3. The measure of the smaller and larger angle will be 27.02 and 62.9 respectively.

A factory makes tissue boxes. When the net is folded to make the tissue box, the length is 25 cm, the width is 5 cm, and the height is 20 cm. How much cardboard material is used to make each tissue box?
Answer:
1450 cm
Step-by-step explanation:
A cardboard box is shaped like a rectangular prism.
To solve the above question, we apply the formula for Surface Area of a Rectangular Prism
A=2(wl+hl+hw)
Where
w = width = 5cm
I = length = 25cm
h = height = 20 cm
=2 × (5×25+20×25+20×5)
= 2(125 + 500 + 100)
= 2(725)
=1450 cm of cardboard material should be used.

evaluate 24 + |x - 4| - y if x=2 and y= -3
Help me plz
Answer:
[tex] \huge \boxed {29}[/tex]
Step-by-step explanation:
[tex]24 + |x - 4| - y[/tex]
Given x = 2 and y = -3. Therefore, substitute x = 2 and y = -3 in the expression.
[tex]24 + |2 - 4| - ( - 3) \\ 24 + | - 2| + 3[/tex]
Multiplying the negative with negative equal positive. All negative numbers in the absolute will become positive.
[tex]24 + 2 + 3 = 24 + 5 = 29[/tex]
Therefore the answer is 29.
Answer:
29
Step-by-step explanation:
Note that the absolute value function always give a positive value, that is
| - a | = | a | = a
Given
24 + | x - 4 | - y ← substitute x = 2, y = - 3 into the expression
= 24 + | 2 - 4 | - (- 3)
= 24 + | - 2 | + 3
= 24 + 2 + 3
= 29

1. find the mean amount
charged = $ ?
=======================================================
Work Shown:
To find the average price, we will add up the 9 values in column 2 to get
120+272+358+328+406+392+530+592+610 = 3,608
Then divide that total by 9 since there are 9 values we added up
We get the average to be (3,608)/9 = 400.888 which is approximate. This rounds to 400.89
Side note: It's a bit strange how your teacher mentions "charge in pounds" but then uses a dollar sign.
Step-by-step explanation:
To find the mean, you add all the numbers together then divide by the number of numbers.
Charge : 120+272+358+328+406+392+530+592+610=3608/9=400.888888 =400.89 dollars
