A school purchases boxes of candy bars. Each box contains 50 candy bars. Each box costs $30. How much does the school have to charge for each candy bar to make a profit of $10 per box?
A $0.40
B $0.50
С $0.80
D $1.25
Answer:
C
Step-by-step explanation:
30/50 = each bar costs 0.60 dollars
10/50 = 0.20 dollars
0.60 + 0.20 = 0.80
What is the diameter of a hemisphere with a volume of 863 in', to the nearest tenth
of an inch?
Answe 33.2
Step-by-step explanation:
863÷3.14=274.8407643312 find the square root then multiply by 2
The diameter of the hemisphere is twice the radius,
d = 2r ≈ 16.6 inches
What is volume?Volume is the measure of the amount of space occupied by a three-dimensional object. It is usually expressed in cubic units, such as cubic meters, cubic feet, or cubic centimetres.
The volume of a hemisphere is given by V = (2/3)πr³, where r is the radius of the hemisphere.
We can solve for the radius as follows:
V = (2/3)πr³
863 = (2/3)πr³
r³ = (863 x 3) / (2π)
r³ ≈ 650.35
r ≈ 8.3 inches
The diameter of the hemisphere is twice the radius, so:
d = 2r ≈ 16.6 inches

The circumference of a circle is 9π m. What is the area, in square meters? Express your answer in terms of π
Answer:
[tex]20.25\pi\:\mathrm{m^2}[/tex]
Step-by-step explanation:
Formulas to know:
Area of a circle: [tex]A=r^2\pi[/tex]Circumference of a circle: [tex]C=2r\pi[/tex]Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:
[tex]9\pi=2r\pi,\\9=2r,\\r=4.5[/tex]
Now we can plug in [tex]r=4.5[/tex] into the formula for an area of a circle:
[tex]A=4.5^2\pi=\boxed{20.25\pi\:\mathrm{m^2}}[/tex]
Answer:
20.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
9 pi = 2 * pi *r
Divide each side by 2pi
9pi / 2 pi = 2 pi r / 2 pi
4.5 = r
Now we can find area
A = pi r^2
= pi ( 4.5)^2
20.25 pi
Thomas paid $4.25 for three apples and four oranges. Five apples and two oranges cost Casey $4.75. Let x represent the number of apples and y represent the number of oranges. Which system of equations represents this situation? A $~3x+4y=4.75~$ $~5x+2y=4.25~$ B 3x+4y=4.25 5x+2y=4.75 C 4x+3y=4.75 2x+5y=4.25 D 4x+3y=4.25 2x+5y=4.75
Answer:
B
Step-by-step explanation:
For the given situation, system of equations is represented by
3x + 4y = 4.25
5x + 2y = 4.75
What is system of equations?"A system of equations is a finite set of equations for which we find the common solution."
According to question,
x represents number of apples
y represents number of oranges.
Two situations are given for which we need to find out which system of equations it represents.
Situation 1 : Thomas paid $4.25 for the three apples and four oranges , which can be represented by equation:
3x + 4y = 4.25
Situation 2: Casey paid $4.75 for five apples and two oranges, which can be represented by equation:
5x + 2y = 4.75

Find the value of r.
Answer:
r = 10.5
Step-by-step explanation:
using the Pythagorean theorem:
(7 + r)² = 14² + r²
49 + 14r + r² = 196 + r²
subtract r² from both sides of the equation:
14r + 49 = 196
subtract 49 from both sides:
14r = 147
divide both sides by 14:
r = 10.5

You need to hire a company to clean your house. Klean company has a fixed cost of $20 and charges $25/hour.
Dustbuster cleaning services, charges $35 per
hour.
a) Write the equations for both companies to calculate the cost of cleaning your house. Include "let" statements.
Answer:
Klean company = 20 + 25h
Dustbuster cleaning services = 35h
Step-by-step explanation:
Let
Number of hours = h
Equation to calculate the cost of cleaning your house
Klean company = 20 + 25h
Dustbuster cleaning services = 35h
Find the number of hours when the cost of cleaning house by both companies will be equal
Klean company = Dustbuster cleaning services
20 + 25h = 35h
20 = 35h - 25h
20 = 10h
h = 20/10
h = 2 hours
Number of hours = h = 2 hours

Find the sum of the 1st 100 terms: 100+98+96+....
Answer:
First we Check if its an AP or GP
Its an AP because the Second term Minus the First term is = to 3rd term Minus Second term
Since it said "Sum"
The formula we should think Of is
Sn = n/2[2a + (n-1)d]
n=100
a(First term) =100
Common difference 'd' = Second term - First term or Third term - Second term
So
d= 98-100 or 96-98
d=-2.
Applying the Formula...
Sn = 100/2 [2(100) + (100-1)(2)]
Sn = 50[200 + (99)(2)]
Sn= 50[200 + 198]
Sn = 50[398]
Sn = 19,900.

Is it linear , quadratic, exponential
Answer:
Exponential
Step-by-step explanation:
So lets look at the table.
When x = 1, y = 3
When x = 2, y = 9.
Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.
So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.
This leaves exponential or none of the above.
When x = 3, y = 27
When x = 4, y = 81
This seems like a exponent, since:
3 to the first power is 3
3 to the second power is 9
3 to the third power is 27
and 3 to the fourth power is 81
Answer:
exponential function

The equation of a parabola is y=x^2–4x+13. Write the equation in vertex form.
Simplify any fractions.
Answer:
y = (x - 2)² + 9
Step-by-step explanation:
To obtain the equation in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 13
= (x - 2)² + 9 ← in vertex form
Answer:
vertex form : y=(x-2)^2+9
Step-by-step explanation:
To convert a parabola from standard form y=x^2-4x+13 to vertex form, we complete the square.
first, complete the square using the x-terms, use the constant term to adjust and make a perfect square.
y= x^2-4x+4 + 9
Factor the first three terms on the right-hand side.
y=(x-2)^2 + 9
the resulting express is then the vertex form, which means that
the vertex is at (x-2) = 0, x=2, and at y=9.

The picture shows
the layout of a
regular triangular
pyramid. Calculate
how many square
centimeters of paper
are needed to make
this pyramid. Provide
the answer to the
nearest square
centimeter.
Answers:
a) 693 sq cm (approximate)b) 48 sq cm (exact)============================================================
Explanation:
Part (a)
A regular triangular pyramid, aka regular tetrahedron, has all four triangles that are identical copies of one another. They are congruent triangles. This will apply to part (b) as well.
To find the area of one of the triangles, we'll use the formula
A = 0.25*sqrt(3)*x^2
where x is the side length. This formula applies to equilateral triangles only.
In this case, x = 20, so
A = 0.25*sqrt(3)*x^2
A = 0.25*sqrt(3)*20^2
A = 173.20508 approximately
That's the area of one triangle, but there are four total, so the entire area is about 4*173.20508 = 692.82032 which rounds to 693 sq cm.
The units "sq cm" can be written as "cm^2".
----------------------------
Part (b)
We'll use the same idea as part (a). But the formula to find the area of one triangle is much simpler.
The area of one of the triangles is A = 0.5*base*height = 0.5*6*4 = 12 sq cm.
So the area of all four triangles combined is 4*12 = 48 sq cm
This area is exact.
The area of each 2D flat net corresponds exactly to the surface area of each 3D pyramid. This is because we can cut the figure out and fold along the lines to form the 3D shapes.
The box-and-whisker plot summarizes student scores on a physical fitness test. Students receive an award for scores at or above the upper quartile. What is the lowest score a student can get to receive an award?
Answer:
74
Step-by-step explanation:
To receive an award, student must obtain a score at or above the upper quartile, from.tye boxplot, the upper quartile is depicted by the endpoint of the box. Hence, the upper quartile of the distribution is 74. Hence only stude Ts who score 74 and above will receive an award Hence, the minimum score required is 74.
