A round tabletop is 6' in diameter. A sample jar of paint will cover 30 square feet. Is there enough paint to cover the tabletop?
Answer:
Yes, there is enough paint to cover the table top.
Step-by-step explanation:
We are told in the above question that the table top is round = circular
The area of a circle = πr²
Diameter = 6 feet
Radius = Diameter/2 = 6 feet/2 = 3 feet
Area of the table top= π × 3²
= 28.27 square feet
We are told that the a sample jar will cover 30 square feet.
Therefore, yes, there is enough paint to cover the table top.

Hi there!
[tex]\large\boxed{x = 16}[/tex]
.5x + 3 = 11
To begin, we can subtract 3 from both sides:
.5x + 3 - 3 = 11 - 3
.5x = 8
To cancel out the .5, we must multiply both sides by 2: (.5 × 2 = 1)
2(.5x) = 2(8)
x = 16.

A hospital near a ski resort records the types of injuries treated during ski season and other seasons
over a year. The results shown in the table will help determine the medical staff that is required at
different times of the year. According to the data in the table, what is the probability that a patient will
need to be treated for a broken bone during ski season?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the types of injuries and the frequency of each injury are not given.
A general way to solve a question like this, is as follows;
First: Calculate the total frequency.
Assume the given dataset is:
[tex]\begin{array}{cc}{Injury} & {Frequency} & {Dislocation} & {20} & {Strain} & {5} & {Broken\ Bone} & {10} & {Bruise} & {15} \ \end{array}[/tex]
The total frequency is:
[tex]Total =20 + 5 + 10 + 15[/tex]
[tex]Total =50[/tex]
Next, write out the frequency of broken bone injuries
[tex]Broken\ Bone = 10[/tex]
Calculate the probability by dividing the number of broken bone by the total frequency
[tex]Pr= \frac{10}{50}[/tex]
[tex]Pr = 0.20[/tex]

Answer:
[tex]K=6[/tex]
Step-by-step explanation:
In f(x) graph the vertex is at x=4
In g(x) the vertex at x=-2
so, the graph is shifted 6 units left. when the graph is shifted k units left then f(x) becomes f(x+k)
here the graph is 6 units left so.. K= 6

Answer:
2.25$
Step-by-step explanation:
The cost of each cupcake the food court mall sells is $2.28.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Desiree works at a dessert counter in the food court of a mall. The dessert counter sells cupcakes and cookies.
Each cookie costs $1.25 and assuming the cost of the cupcake is x.
∴ (1.25×12) + (8x) = 33.30.
15 + 8x = 33.30.
8x = 18.3
x = 2.28

Ralph has a cylindrical container of parmesan cheese. The diameter of the base of the container is 2.75 inches, and the height is 6 inches. What is the area of a horizontal cross section of the cylinder to the nearest tenth of a square inch?
Answer:
The solution is given below:
Step-by-step explanation:
The computation of the area of the horizontal cross section of the cyclinder is given below:
In the case when it is a circle
The area of the circle is
= πr^2
= 3.14 × (2.75 ÷ 2)^2
= 11.873 inches^2
In the case when it is a rectangle
The area of the rectangle is
= 6 × 2.75
= 16.5 inches^2
Hence, the above show the calculations
The area of the horizontal cross section.
When circular is [tex]11.873 inches^2[/tex]
When it is rectangular [tex]16.5inches^2[/tex]
The computation of the area of the horizontal cross section of the cylinder
What is the formula of the area of the circle?The area of the circle is[tex]=\pi r^{2}[/tex]
use the given value in above formula we get,
[tex]= 3.14 \times (\frac{2.75}{2} )^2[/tex]
[tex]= 11.873 inches^2[/tex]
when it is a rectangle then the area of the rectangle is
[tex]= 6 \times 2.75[/tex]
[tex]= 16.5 inches^2[/tex]
Therefore,the area of the horizontal cross section.
when circular is [tex]11.873 inches^2[/tex]
When it is rectangular [tex]16.5inches^2[/tex]

What is the coordinate of the focus
for the following parabola:
(x - 1)^2 = 12(y + 2)
Answer:
D
Step-by-step explanation:
The required focus of the parabola (x - 1)^2 = 12(y + 2) is (1, 1). Option D is correct.
Given that, equation of the parabola,
[tex](x - 1)^2 = 12(y + 2)[/tex]A parabola is cross-section cut out of the cone and represented by an equation [tex]y = 4ax^2[/tex]. Where a is focus.
Here,
[tex](x - 1)^2 = 12(y + 2)[/tex]
Simplify the above parabola equation to stand equation
[tex]y = \frac{1}{4(f-k)} (x-h)^2 + k[/tex]
[tex]y =\frac{1}{4(1-(-2))} (x - 1)^2 - 2[/tex]
Now comparing above the equation,
vertex of a parabola,
h = 1 and k = -2
And focus
So the coordinate of the focus of the parabola = (h, f)
= (1, 1)
Thus, the required focus of the parabola (x - 1)^2 = 12(y + 2) is (1, 1). Option D is correct.

A faraway planet is populated creatures called Jolos. All Jolos are either
green or purple and either one headed or two-headed.
Balan, who lives on this planet, does a survey and finds that her colony of 500
contains 100 green, one-headed Jolos; 125 purple, two-headed Jolos; and
270 one-headed Jolos.
Your answer is B. 205.
Because when you subtract 270 - 100 it equals 170 then you add 170 + 125 which equals 295 then you subtract 500 - 295 it equals 205 which is your answer!
