The trigonometric ratios that Garret could use to describe the relationship between these two sides are sin 30°and cos 60°.
What are Trigonometric Ratios?Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.
The main three trigonometric ratios are sine, cosine and tangent functions.
here, we have,
Given that,
Garret makes a ramp for his skateboard in the shape of a right triangle.
Also given that,
length of the hypotenuse = 2 feet
Length of a leg = 1 feet
Using Pythagoras theorem,
Length of other leg = √(2² - 1²) = √3
45°-45°-90° triangle ratio is 1 : 1 : √2.
30°-60°-90° triangle ratio is 1 : √3 : 2.
Given triangle has the side ratio 1 : √3 : 2. So this is a 30°-60°-90° triangle.
The trigonometric ratio used must include the hypotenuse.
So sin and cos can only be used.
Hence the trigonometric ratios used are sin 30°and cos 60°.

Find the volume of an oblique circular cylinder that has a radius of five feet and a height
of three feet
Answer:
235.5 cubic feet
Step-by-step explanation:
The volume v of a circular cylinder whose base radius is r and height h is given as
v = πr^2h
where π is 22/7 or 3.14
Given that the radius is five feet and the height is three feet
the volume v = 3.14 *5^2 * 3
= 235.5 cubic feet
The volume of the oblique circular cylinder is 235.5 cubic feet

(Student's Solution): "Factor the polynomial"
y^2-6y+9=y^2-2(y)(3)+3^2 = (y-3)(y+3)
Note: Please help, I have been working on this for like 4 days im so tired.
Answer:
See below.
Step-by-step explanation:
y^2 - 6y + 9 can be changed correctly into y^2 - 2(y)(3) + 3^2.
Up to here, it's correct.
The right side above shows a polynomial that is the square of a binomial.
It factors into (y - 3)^2.
The correct factorization is (y - 3)^2.
The incorrect factorization of the student's solution is the product of a sum and difference.
The product of a sum and a difference is the correct factorization for a difference of squares.
For example, y^2 - 9 is the same as y^2 - 3^2 and is a difference of squares.
It factors into (y + 3)(y - 3), a product of a sum and a difference.

the average can be calculated by adding the scores together and then dividing by the number of scores.
we can set up an equation:
let x = test score needed on next test
(72+72+80+x)/4 = 71
multiply both sides by 4
72+72+80+x = 284
add like terms
224+x=284
subtract 224 from both sides
x=60
she will need a 60 for her average to be 71
She needs to score a 60 to have a average score of 71,
72+72+80+60=284
284/4=71

Ariana has 99 oranges. She has to pack 9 boxes with an equal number of oranges. How many oranges should she pack in each box?
Answer:
11 oranges in each box
Step-by-step explanation:
99/9=11
Answer: 11 oranges in each box.
Step-by-step explanation:
Division is used to evenly separate totals into groups (total/#of groups= Quotient per group).
In this case, we divide the total, 99 oranges, by the amount of groups we want, which is 9 boxes, in order to find an even amount for each box from the total oranges.
So, 99/9= 11 oranges per box

A small business owner is determining her profit for one month. Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries. She made $11,449.27 in sales for the month. What is her profit?
Her profit would amount to $4564.24 for one month which is determined by subtracting her total expenses from made revenue.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
For the month, she made a revenue of $11,449.27.
To calculate her profit, we have to subtract her total expenses from made revenue.
Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries which are given in the question.
Total expenses = 230.21 + 2,679.82 + 3,975.00 = 6885.03
As per the given data, the solution would be:
⇒ Total revenue - Total expenses
⇒ 11,449.27 - 11,449.27
Apply the subtraction operation, and we get
⇒ 4564.24
Therefore, her profit would amount to $4564.24 for one month.

What percentage of Americans would you predict wear glasses?
Answer: 64%
75% of adults use some sort of vision correction. About 64% of them wear eyeglasses, and about 11% wear contact lenses, either exclusively, or with glasses. Over half of all women and about 42% of men wear glasses.
63.8% of Americans are predicted to wear glasses
How to determine the percentage?The given parameters are:
Glasses = 638Sample size = 1000The percentage of Americans that wear glasses is calculated as:
Percentage = Glasses/Sample size
This gives
Percentage = 638/1000
Evaluate the quotient
Percentage = 0.638
Express as percentage
Percentage = 63.8%
Hence, 63.8% of Americans would wear glasses

What are Trignometric ratios ?The ratios of the sides of a right triangle are called trigonometric ratios.
Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
sin = Perpendicular/ Hypotenuse
Cos = Base / Hypotenuse
tan = Perpendicular/Base
In the figure attached with the answer we can see that in Triangle ABC ,
tan 50.1 = x / 5
5(tan 50.1) = x
Therefore x is approximately equal to 6.

11) Krystal and Rob each improved their yards by planting hostas and ivy. They bought their
supplies from the same store. Krystal spent $132 on 8 hostas and 4 pots of ivy. Rob spent $44
on 2 hostas and 2 pots of ivy. What is the cost of one hosta and the cost of one pot of ivy?
Answer: Cost of one hosta = $11
Cost of one pot of ivy = $11
Step-by-step explanation:
Let the the cost of one hosta be represented by x.
Let the cost of one pot of ivy be represented by y.
The information given in the question can be formed into an equation as:
8x + 4y = 132 ............ i
2x + 2y = 44 ............. ii
Multiply equation i by 2
Multiply equation ii by 4
16x + 8y = 264 ........ iii
8x + 8y = 176 ........ iv
Subtract iv from iii
8x = 88
x = 88/8
x = 11
One hosta cost $11
From equation ii
2x + 2y = 44
2(11) + 2y = 44
22 + 2y = 44
2y = 44 - 22
2y = 22
y = 22/2
y = 11
One pot of ivy cost $11
