What is the probability of rolling an odd number and then rolling a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
2/3
Step-by-step explanation:
There are 3 odd numbers in a dice which equals 1/2. Then there is 1/6 of a chance of rolling a 3. So it would be 1/2 + 1/6=4/6 which simplifies to 2/3.
Nguyen is decorating the room for her sister’s baby shower party. She is wrapping Vietnamese conical hats in baby prints tissue paper to decorate the tables and some shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
Answer:
She needs 301.8 in² of tissue paper.
Step-by-step explanation:
In order to calculate the amount of tissue paper she needs to make 21 hats, we need to find the area of each hat and multiply it by the total number of hats she wants to make.
Since the Vietnamese conical hats are hollow and don't have a base, we need to find the area of the it's lateral walls, this is given by the following expression:
lateral area = pi*r*l
r = d/2 = 16/2 = 8 in
We were given the height, but we need the slant height, therefore:
l = sqrt(r² + h²) = sqrt(8² + 9²) = sqrt(64 + 81) = sqrt(145) = 12.041 in
Then the lateral area is:
lateral area = pi*8*12.0141 = 301.8 in²
She needs 301.8 in² of tissue paper.

A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled. Part A: If the total cost of the fare was $41.00, then which of the following equations can be used to determine the number of miles traveled, x?What is the total number of miles traveled, x, if the fare was $41.00?
Answer:
5 + 3x = 41
x = 12 miles
Step-by-step explanation:
A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled.
Let x is the number of miles traveled.
If the total cost of the fare was $41.00 then
5 + 3x = 41 eq. 1
The above equation can be used to determine the number of miles traveled.
Solving the equation for x,
5 + 3x = 41
3x = 41 - 5
3x = 36
x = 36/3
x = 12 miles
Therefore, 12 is the total number of miles traveled if the fare was $41.00.

Two fifths of the performance were sold out. There were 15 performances that were not sold out. a. How many performances were there? b. What was the ratio sold out to not sold out performances?
Answer:
25
2:3
Step-by-step explanation:
2/5 were sold out
5/5 - 2/5 = 3/5
That means 3/5 were not sold out
p = performances
there were 15 that were not sold out
3/5 * p = 15
Multiply each side by 5/3
5/3 *3/5 p = 15*5/3
p = 25
There were 25 performances
sold out to not sold out

f(x) = (x+2)^2+4 . what are the coordinates of the vertex?
Answer:
[tex](-2,\, 4)[/tex].
Step-by-step explanation:
To find the vertex of this parabola, start by rewriting it in the vertex form [tex]f(x) = a\, (x - h)^2 + k[/tex].
Start with the original expression:
[tex]f(x) = (x + 2)^2 + 4[/tex].
Note that in the vertex form, the sign in front of [tex]h[/tex] should be a minus. However, in [tex]f(x) = (x + 2)^2 + 4[/tex], the sign in front of [tex]2[/tex] is a plus. Since adding
[tex]f(x) = (x - (-2))^2 + 4[/tex].
Therefore:
[tex]h = -2[/tex],[tex]k = 4[/tex].Hence, [tex](-2,\, 4)[/tex] is the vertex of this parabola.
Find the coordinates of the point for the reflection.
(−4, 8) across the x-axis
The coordinates of the reflection are
Answer:
The point after the reflection: [tex](-4,-8)[/tex]
Step-by-step explanation:
-Statement: If you reflect the point [tex](x,y)[/tex] across x-axis or the y-axis, then the [tex]x[/tex] and the [tex]y[/tex] of the point can change either positive, negative or the same, depending on where the point is located on a graph.
-So, if you reflect the point [tex](-4,8)[/tex] across x-axis, then the point after the reflection, would be [tex](-4, -8)[/tex] :
The following point: [tex](-4, 8)[/tex]
The point after the reflection: [tex](-4,-8)[/tex]
A container shapes like an inverted cone holds 96 cubic centimeters of water. The height of the cup is 14 centimeters. Find the length of the diameter?
Answer:
Cone Volume = (PI * radius^2 * height) / 3
96 cc = (PI * radius^2 * 14) / 3
(96 * 3) / (PI * 14) = radius^2
radius ^ 2 = 6.5480890872
radius = 2.5589234235
diameter = radius *2 = 5.117846847 cm
diameter = 5.12 cm (rounded)

Enrollment in a dance studio has grown exponentially since the studio opened. A graph depicting this growth is shown. Determine the percentage rate of growth.
0.25%
1.25%
2.5%
25%
Answer:
Option (4). 25%
Step-by-step explanation:
The graph attached shows the exponential growth.
Let the graphed function is y = [tex](1+\frac{r}{100})^{t}[/tex]
Here 'r' = Rate of growth
t = Duration of time in years
y = enrollments after time 't' years
Graph shows at time 't' = 0 or initially number of enrollments = 20
After 8 years number of enrollments will be
120 = [tex]20(1+\frac{r}{100})^{8}[/tex]
[tex]\frac{120}{20}=(1+\frac{r}{100})^{8}[/tex]
6 = [tex](1+\frac{r}{100})^{8}[/tex]
log 6 = [tex]8\text{log}(1+\frac{r}{100})[/tex]
0.77815 = [tex]8\text{log}(1+\frac{r}{100})[/tex]
[tex]\text{log}(1+\frac{r}{100})[/tex] = 0.0972689
[tex](1+\frac{r}{100})=1.251[/tex]
[tex]\frac{r}{100}=0.251[/tex]
r = 25.1%
r ≈ 25%
Therefore, Option (4) will be the answer.

i dont understand your question
The function h ( x ) = 1 x − 1 h ( x ) = 1 x - 1 can be expressed in the form f ( g ( x ) ) f ( g ( x ) ) , where g ( x ) = ( x − 1 ) g ( x ) = ( x - 1 ) , and f ( x ) f ( x ) is defined as:
Answer: f(x) = 1^(x + 1)
Step-by-step explanation:
we have that h(x) = 1^x
and h(x) = f(g(x))
This mean that we are evaluating the function f(y) in the point y = g(x)
where g(x) = x - 1
then:
f(g(x) = f(x - 1) = h(x) = 1^x
then we should have that:
f(x) = 1^(x + 1)
then:
f(x - 1) = 1^(x - 1 + 1) = 1^x

Is every trapezoid a rectangle
Answer:
No, a trapezoid is not a rectangle.
This is because trapezoids by definition have only one pair of parallel sides while rectangles must have at least two sets of opposite parallel sides. Also, trapezoids do not have 90 degrees at every angle like rectangles do.
Let p=x^2-2p=x 2 −2p, equals, x, squared, minus, 2. Which equation is equivalent to (x^2-2)^2+18=9x^2-18(x 2 −2) 2 +18=9x 2 −18left parenthesis, x, squared, minus, 2, right parenthesis, squared, plus, 18, equals, 9, x, squared, minus, 18 in terms of ppp ?
Question:
Let [tex]p=x^2-2[/tex] .
Which equation is equivalent to in terms of p ?
Answer:
[tex]p^2+18=9p[/tex] or [tex]p^2+18 - 9p = 0[/tex]
Step-by-step explanation:
Given
[tex]p=x^2-2[/tex] .
Required
Find the equation equivalent to [tex](x^2-2)^2+18=9x^2-18[/tex]
To get the equation equivalent to the given expression, we simply simplify [tex](x^2-2)^2+18=9x^2-18[/tex] and solve in terms of p
[tex](x^2-2)^2+18=9x^2-18[/tex]
Factorize expression on the right hand side
[tex](x^2-2)^2+18=9(x^2-2)[/tex]
Substitute [tex]x^2 - 2[/tex] for p
[tex](x^2-2)^2+18=9(x^2-2)[/tex] becomes
[tex]p^2+18=9p[/tex]
Hence, equation [tex]p^2+18=9p[/tex] is equivalent to [tex](x^2-2)^2+18=9x^2-18[/tex]
Solving further to get the value of p
[tex]p^2+18=9p[/tex]
Subtract 9p from both sides
[tex]p^2+18 - 9p = 9p - 9p[/tex]
[tex]p^2+18 - 9p = 0[/tex]
Rearrange
[tex]p^2 - 9p +18 = 0[/tex]
Factorize
[tex]p^2 - 6p - 3p +18 = 0[/tex]
[tex]p(p - 6) - 3(p -6) = 0[/tex]
[tex](p - 3)(p -6) = 0[/tex]
p - 3 = 0 or p - 6 = 0
p = 3 or p = 6
Answer:
p^2-18+9p=0
