Answer:
Total cost= $975
Step-by-step explanation:
Giving the following information:
Total cost= 100 + 5*n
n= number of students
The $100 is a fixed cost. It remains constant no matter the number of students. The $5 is the unitary variable cost. The total variable cost increases with the number of students.
Total cost for 175 students:
Total cost= 100 + 5*175
Total cost= $975

Answer:
15.13cm
Step-by-step explanation:
From that above question:
We are told that:
Lateral surface area of a right circular cone : πr√r² + h²
We are give the following parameters:
Lateral surface area = 236.64cm²
Radius = 4.75cm
We are to find the height
Making h the subject of the formula
h = √[(A/r)² - πr²]/π
h = √[(236.64/4.75)²- π ×4.75²]/π
h = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm
In a triangle ABC, AC=24 cm, BC=30 cm, and m∠C=40°. Determine the area of the triangle. Round to nearest square centimeter.
Answer:
The area of the triangle is 231 cm² to the nearest square centimeter
Step-by-step explanation:
We can find the area of a triangle has the lengths of two sides and the measure of the included angle by using the trigonometry
A = [tex]\frac{1}{2}[/tex] × s1 × s2 × sinФ, where
s1 and s2 are the two sides of the triangleФ is the angle included between s1 and s2In ΔABC
∵ AC = 24 cm
∴ s1 = 24
∵ BC = 30 cm
∴ s2 = 30
∵ m∠C = 40°
∴ Ф = 40°
→ By using the rule of the area above
∵ A = [tex]\frac{1}{2}[/tex] × 24 × 30 × sin(40°)
∴ A = 231.4035395 cm²
→ Round it to the nearest square centimeter
∴ A = 231 cm²
∴ The area of the triangle is 231 cm² to the nearest square centimeter

Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Answer:
211 months
Step-by-step explanation:
Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Let the number of months that he prepays for be represented by m
Hence, we have the equation
$20 + $15 × m = $3185
Hence:
20 + 15m = 3185
Collect like terms
15m = 3185 - 20
15m = 3165
m = 3165/15
m = 211 months
Jiangsu divided 751.6 by 10 to the second power and obtained a quotient of 0.7516. Yessenia thinks the quotient. Who has the reason? Explain your answer.
Answer:
Yessenia is correct.
Step-by-step explanation:
Supose Yessenia thinks the quotient is 7.516, then Yessenia is correct.
The reason why Yessenia is correct is that, if we interpret the question mathematically, we have:
[tex]= \dfrac{751.6}{10^2}[/tex]
[tex]= \dfrac{751.6}{100}[/tex]
From above the decimal point will shift to the left twice since we are dividing 751.6 by 100, which is:
= 7.516 and not 0.7516
A pair of jeans is on sale for 20% off. The sale price is $55.00. What is the original amount of the pair of jeans?
Answer: 275$
I'm not entirely sure I did this right! But at least try!!!
Step-by-step explanation:
20/100 = 55/x (cross multiply)
20x = 5,500 (divide)
X = 275
The original price of the pair of jeans is $ 68.75
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The sale price of the jeans = $ 55.00
The discounted percentage of the pair of jeans = 20 %
Let the original price of the jeans be = A
To calculate the original price of the jeans ,
Original price of the jeans A will be discounted percentage less than and is equal to the sale price of the jeans
So ,
Original price of the jeans A - discounted percentage of the pair of jeans = Sale price of the jeans
And ,
A - ( 20/100 ) A = 55
( ( 100A - 20A ) / 100 )A = 55
(80/100 ) A = 55
( 4/5 ) A = 55
Multiply by 5/4 on both sides , we get
A = ( 55 x 5 ) / 4
A = 275/4
A = $ 68.75
Therefore , Original price of the jeans A = $ 68.75
Hence , the original price of the jeans is $ 68.75

A student is solving the equation 21 y + 3) = 14 for y. Which of these could be the next step?
1. Distribute on the left hand side to get 2y +3 = 14
2. Divide both sides by 2 to get y+3 = 7
3. Distribute on the left hand side to get 2y +6 = 14
4. Subtract 3 from both sides to get 2y = 11
5. Divide both sides by 2 to get y+3 = 14

Marcus bought school supplies for $42.00, not including tax. If the tax rate was 8.5%,
what was the total cost of the school supplies, including tax?
Answer:
$45.57
Step-by-step explanation:
First, calculate the dollar amount of the tax. This can be done by multiplying the price by the sales tax percentage
$42 × 8.5%= $3.57
Now, add the sales tax amount back to the price.
42 + 3.57 = 45.57
Jessica needs 233 feet of wood to build a fence the word comes in length of 11 feet how many pieces of wood should Jessica by Samuel needs twice as many feet as Jessica how many pieces of wood does Samuel need
Given :
Jessica needs 233 feet of wood to build a fence the word comes in length of 11 feet.[tex]N= 21\times 2[/tex]
To Find :
How many pieces of wood should Jessica by Samuel needs twice as many feet as Jessica how many pieces of wood does Samuel need.
Solution :
Total number of pieces of wood Jessica needs is :
[tex]n = \dfrac{233}{11}\\\\n = 21.18[/tex]
Since number of pieces cannot be negative.
So, n = 21
It is given that Samuel needs twice as many feet as Jessica need.
So,
N = 21 × 2 = 42
Therefore, Samuel needs 42 pieces of wood.

There are 4 birds and 6 snakes. What is the ratio of birds to snakes?
Answer:
4/6
Step-by-step explanation:
it says birds first so the bird number goes first
The ratio of birds to snakes is 2:3 if there are 4 birds and 6 snakes the answer is 2:3.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
There are 4 birds and 6 snakes.
Number of birds = 4
Number of snakes = 6
The ratio = birds: snakes
= 4: 6
On simplifying:
= 2:3
Thus, the ratio of birds to snakes is 2:3 if there are 4 birds and 6 snakes the answer is 2:3.

How do I find the 5 roots of 1^(1/5) using De Moivre's Theorem?
Do you mean the 5th roots of 1? Or the 5th roots of 1^(1/5), i.e. the 5th roots of the 5th roots of 1?
I assume you mean the former. To begin with,
1 = exp(0°i ) = cos(0°) + i sin(0°)
Take the 5th root, i.e. (1/5)th power of both sides, so that by DeMoivre's theorem,
1^(1/5) = [ cos(0°) + i sin(0°) ]^(1/5)
1^(1/5) = cos((0° + 360°n)/5) + i sin((0° + 360°n)/5)
where n = 0, 1, 2, 3, or 4. Then 1^(1/5) has the 5 possible values,
• cos(0°/5) + i sin(0°/5) = 1
• cos(360°/5) + i sin(360°/5) = cos(72°) + i sin(72°)
• cos(720°/5) + i sin(720°/5) = cos(144°) + i sin(144°)
• cos(1080°/5) + i sin(1080°/5) = cos(216°) + i sin(216°)
• cos(1440°/5) + i sin(1440°/5) = cos(288°) + i sin(288°)
If you wish, or are required to, you can go on to write these in terms of radicals by expanding cos(5x) and sin(5x) (where x = 72° so that 5x = 360°). For example,
cos(5x) = cos⁵(x) - 10 cos³(x) sin²(x) + 5 cos(x) sin⁴(x)
cos(5x) = cos⁵(x) - 10 cos³(x) (1 - cos²(x)) + 5 cos(x) (1 - cos²(x))²
cos(5x) = 16 cos⁵(x) - 20 cos³(x) + 5 cos(x)
which follows from the expansion
(cos(x) + i sin(x))⁵ = cos(5x) + i sin(5x)
due to DeMoivre's theorem and equating the real parts. Then cos(5x) = 1, and you can try to solve for cos(x) :
1 = 16 cos⁵(x) - 20 cos³(x) + 5 cos(x)
Actually, it would be easier to find sin(x) first, since sin(5x) = 0. The expansion in terms of sin(x) will look quite similar to the one shown here.

The answer is "Angle-Angle-Angle".

Please find the image file in the attachment.
The angle of an image, composed of two rays at such a popular end-state, could be described. Angles with a tape measure are measured in degrees, When the three angles congruence between two triangles, that is NOT the congruence of a triangle. It seems to be the same (and similar form, yet we know nothing of their scale. We may call us comparable.
