Answer:
252 7 x 3 x 2
Step-by-step explanation:
The boy can wear 252 different outfits to school.
To calculate the number of different outfits, you can multiply the number of choices for each clothing item.
In this case, he has 7 choices of pants, 3 choices of shirts, 2 choices of ties, and 6 choices of jackets.
To find the total number of outfits, simply multiply these choices together: 7 pants x 3 shirts x 2 ties x 6 jackets = 252 different outfits.
This calculation works because for each choice of one item of clothing, there are still all the other choices available for the remaining items.
So, for every pair of pants, he can choose from 3 different shirts, and for each shirt-pants combination, there are 2 tie options, and so on.
Multiplying these choices together gives us the total number of outfits he can create while wearing one of each item.

What is 54 in scientific notation
Answer:
5.2 times 10^1
Step-by-step explanation:
the first number should be less than ten.
Answer: [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here, we have 5.4 and notice that there
is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would
need to move to get back to the original number, 54.
Since we would need to move the decimal point 1 place to the right,
we have an exponent of positive 1.
Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.
So we have [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]
Notice that the exponent is positive.
This is because we would need to move the decimal point to the right in order to get back to the original number.
So 54 can be written in
scientific notation as [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex].
Find the area of a circle with a diameter of 6.
Either enter an exact answer in terms of pi or use 3.14 for pi and enter your answer as a decimal.
To find the area of a circle with a diameter of 6, divide the diameter by 2 to get the radius, then use the formula Area = πr² with the calculated radius, resulting in an area of 28.26.
Using either the exact value of π (pi) or its approximation 3.14, we substitute the radius into the formula to calculate the area.
Using π, the area is:
A = π(3)² = 9π
Using the approximation of 3.14 for π, the area is:
A = 3.14(3)² = 3.14(9) = 28.26
So, the area of the circle is either 9π square units or approximately 28.26 square units if you use 3.14 for π.

Answer:

did test on edge, got 100%
The height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).
The formula for the volume of a rectangular prism is V = Ah, where A is the area of the base and h is the height. Since we are given the volume and the area of the base, we can solve for the height. We have V = ([tex]x^{2}[/tex]-2) * h and V = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3), so we can set these two equations equal to each other and solve for h.
([tex]x^{2}[/tex]-2) * h = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3)
Expanding both sides, we get:
[tex]x^{2}[/tex]h - 2h = [tex]x^{3}[/tex]h - 3[tex]x^{2}[/tex]h + 5xh - 3h
Combining like terms, we get:
([tex]x^{3}[/tex] - 3[tex]x^{2}[/tex] + 5x - 3 - [tex]x^{2}[/tex] + 2 - 5x + 3) * h = 0
Simplifying, we get:
([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) * h = 0
Since [tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2 cannot equal 0 (since it's a cubic polynomial), we can divide both sides by ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) to solve for h:
h = 0 / ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2)
So the height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).

The figure is made up of a semicircle and a triangle. Find the perimeter. Round your answer to the nearest hundredth
Answer:
The perimeter of the figure is 86.53 meters
Step-by-step explanation:
we know that
The perimeter of the figure is equal to the circumference of a semicircle, plus the sum of the legs of the right triangle

Find the circumference of a semicircle
The circumference of a semicircle is given by the formula
[tex]C=\pi r[/tex]
we have
[tex]r=29/2=14.5\ m[/tex] ----> the radius is half the diameter
assume
[tex]\pi =3.14[/tex]
substitute
[tex]C=(3.14)(14.5)=45.53\ m[/tex]
step 2
The sum of the legs of the right triangle is equal to
[tex]20+21=41\ m[/tex]

Find the area of a
regular hexagon with
an apothem of
15 cm.
DO
The area of the regular hexagon is 585 square centimeters.
Explanation:A regular hexagon is a polygon with six equal sides and six equal angles. To find the area of a regular hexagon, you can use the formula:
[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \text{side length}^2 \][/tex]
However, in this case, the apothem (the distance from the center to the midpoint of a side) is given instead of the side length. The relationship between the apothem (\(a\)) and the side length (\(s\)) of a regular hexagon is given by:
[tex]\[ a = \frac{s}{2} \times \sqrt{3} \][/tex]
Rearranging this formula to solve for \(s\), we get:
[tex]\[ s = \frac{2 \times a}{\sqrt{3}} \][/tex]
Substituting this expression for \(s\) into the area formula, we get:
[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \left(\frac{2 \times a}{\sqrt{3}}\right)^2 \][/tex]
Simplifying further:
[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \frac{4 \times a^2}{3} \][/tex]
Canceling out common factors:
[tex]\[ \text{Area} = 2 \sqrt{3} \times a^2 \][/tex]
Now, substituting the given apothem ((a = 15) cm), we find:
[tex]\[ \text{Area} = 2 \times \sqrt{3} \times (15 \, \text{cm})^2 = 585 \, \text{cm}^2 \][/tex]
Therefore, the area of the regular hexagon is 585 square centimeters.

When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?
Answer:
B. x
Step-by-step explanation:
-3x+8y=-6
3x-2y=-12
if we add these
-3x+3x+8y-2y=-6-12
6y=-12 so x will be eliminated
Final answer:
When solving a system by elimination, the variable eliminated is the one with coefficients that add up to zero when equations are combined.
Explanation:
When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?
When adding the two equations together in a system, the variable that will be eliminated will be the one that has coefficients with additive inverse values. For example, if one equation has x and the other has -x, adding them would result in the elimination of the x variable.
After adding the two equations together, look for a pair of variables that will cancel each other out, resulting in the elimination of one variable.

A cylinder has a radius of 24.6 inches and a volume of 29,468 in3. Find its height.
A. 14.5 in
B. 15 in
C.15.5 in
D. 16.5 in
Answer:
15.49 inches
Step-by-step explanation:
Volume of a cylinder is given by
[tex]V=\pi r^{2}h[/tex]
Making h the subject of the formula then
[tex]h=\frac {V}{\pi r^{2}}[/tex]
Where h is the height, V is volume and r is radius. Substituting 24.6 inches for r and 29468 cubic inches for V then
[tex]h=\frac {29468}{\pi 24.6^{2}}=15.493723673378\ in\approx 15.49\ in[/tex]
Therefore, the height is approximately 15.49 inches
The correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).
To find the height of a cylinder with a volume of 29,468 cubic inches (in3) and a radius of 24.6 inches, we use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height.
Plugging in the known values, we get:
29,468 in3 = π(24.6 in)2h
Solving for h, the height of the cylinder, we perform the following steps:
Calculate the base area: Base Area = π(24.6 in)2
Divide the volume by the base area to find the height: h = Volume / Base Area
Calculate the height: h = 29,468 in3 / (π(24.6 in)2)
After performing the calculation, we conclude that the correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).

Answer:
$135.92
Step-by-step explanation:
Just chose Bedroom 3 because it has whole numbers, none of the other rubbish.
The interior surface area of the bedroom can be calculated by the formula:
2lw + 2wh + 2lh
The surface area is 816 feet squared.
Since we are painting the room twice, we can just double this value for the sake of the next step.
The cost per gallon of paint is $33.98.
Each gallon covers 400 ft^2.
The number of gallons required is (816*2)/400, which is 4.08 gallons. If we approximate that we require 4 gallons, then the total cost will be $33.98*4 = $135.92.

What is the height of the cylinder in the diagram? Round your answer to the nearest whole number.
Answer: 8
Step-by-step explanation:
As per the given volume and radius of the cylinder, the height of the cylinder in the diagram is approximately 8 cm.
In order to determine the height of the cylinder in the given diagram, we first need to understand the formula for calculating the volume of a cylinder. The formula for the volume of a cylinder is
=> V = π * r² * h,
where V represents the volume, π is a constant (approximately equal to 3.14159), r is the radius, and h is the height of the cylinder.
In the provided information, we are given that the radius of the cylinder is 6 cm (radius = 6 cm) and the volume of the cylinder is 904.78 cm³ (V = 904.78 cm³).
Now, we can rearrange the volume formula to solve for the height (h) of the cylinder. Divide both sides of the formula by (π * r²):
h = V / (π * r²)
Substitute the known values:
h = 904.78 cm³ / (3.14159 * 6²)
h = 904.78 cm³ / (3.14159 * 36)
h = 904.78 cm³ / 113.09724
h ≈ 7.99998 cm
Rounding the answer to the nearest whole number, the height of the cylinder is approximately 8 cm.
