Given:
Daniel bought a bicycle for $80 and a helmet for $20.
Sales tax = 5%
To find:
The total amount of both items including tax.
Solution:
Price of bicycle (excluding tax)= [tex]\$80[/tex]
Price of helmet(excluding tax) = [tex]\$20[/tex]
Price of both items = [tex]\$80 + \$20[/tex]
=[tex]\$100[/tex]
Now, the sales tax is 5%. So,
Price of both items (including tax) = [tex]\$100+\dfrac{5}{100}(\$100)[/tex]
= [tex]\$100+\$5[/tex]
= [tex]\$105[/tex]
Therefore, the Daniel pays $105 for the two items, including tax.

A butcher shop is selling steaks 2 for $7.00. The butcher sells 29 steaks today. How much money did the butcher make selling steaks today?
Answer:
The butcher made $101.50
Step-by-step explanation:
2 for 7.00
1 steak would be 7.00 divided by 2
7 divided by 2 is 3.5
1 steak is 3.50 dollars
29 steaks in total
29 multiplied by 3.50 is 101.5
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

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.

Hi there!

.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.
Solve the following equation for x.

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.
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!
