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.

for the following parabola:
(x - 1)^2 = 12(y + 2)
Answers
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]What is a parabola?
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 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?
Answers
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]

Answers
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

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?
Answers
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.

contains 100 green, one-headed Jolos; 125 purple, two-headed Jolos; and
270 one-headed Jolos.
Answers
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!
