Answer:
[tex]\frac{y}{x}[/tex], the fourth option.
Step-by-step explanation:
Tan means [tex]\frac{opposite}{adjacent}[/tex] or opposite side divided by adjacent side.
Tan A equals the opposite side of the angle A divided by its adjacent side.
The side opposite of A is y and side adjacent to it is x.
So, Tan A equals [tex]\frac{y}{x}[/tex]!

In terms of c, y, and a , what is the value of x in the equation
2ax + 2y = c?
Answer:
Step-by-step explanation:
Simplifying
2ax + 2y = c
Solving
2ax + 2y = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2y' to each side of the equation.
2ax + 2y + -2y = c + -2y
Combine like terms: 2y + -2y = 0
2ax + 0 = c + -2y
2ax = c + -2y
Divide each side by '2x'.
a = 0.5cx-1 + -1x-1y
Simplifying
a = 0.5cx-1 + -1x-1y
The value of the equation in terms of c, y, and a is (x - 2y)/2a so option (D) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
In another word, the equation must be constrained with some constraints.
Given the equation,
2ax + 2y = c where x and y are variable and c is constant.
Now,
2ax + 2y = c
2ax = x - 2y
Divide by 2a into both sides
x = (x - 2y)/2a
Hence "The value of the equation in terms of c, y, and a is (x - 2y)/2a".

Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

Total number of books borrowed= 16
Step-by-step explanation:
Giving the following information:
Number of non-fictions books= 4
Percentage of books borrowed= 25% = 0.25
To calculate the total number of books borrowed, we need to use the following formula:
Total number of books borrowed= 4 / 0.25

20P4 = 116280
The students can be chosen in 116280 different ways to be elected as president, vice president, treasurer and secretary.
What is permutation?"It is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters."
Formula of permutation:The number of ways of obtaining an ordered set of 'r' elements from a set of 'n' elements.
[tex]^{n}P_r=\frac{n!}{(n-r)!}[/tex]
For given example,
there are 20 students in a homeroom
⇒ n = 20
Students can be elected president, vice president, treasurer and secretary.
⇒ r = 4
So, using the formula of permutation, the number of different ways they can be chosen to be elected president, vice president, treasurer and secretary would be,
[tex]\Rightarrow ^{n}P_r=\frac{n!}{(n-r)!} \\\\\Rightarrow ^{20}P_4=\frac{20!}{(20-4)!} \\\\\Rightarrow ^{20}P_4=\bold{116280}[/tex]

A shopper in a grocery store purchases 22 items on average. A store manager believes that the mean is greater than 22. She surveyed a randomly selected group of 36 customers and found that the mean of the number of items purchased was 23.2. The population standard deviation is 3.7 items. At α = 0.05, can it be concluded that the mean is greater than 22 items?
Answer:
The is no significant evidence to conclude that mean is greater than 22
Step-by-step explanation:
H0 : μ = 22
H0 : μ > 22
The test statistic :
(xbar - μ) ÷ (σ/sqrt(n))
xbar = 22.3 ; n = 36 ; μ = 22 ; σ = 3.7
(22.3 - 22) ÷ (3.7/√36)
0.3 ÷ 0.6166666
Test statistic = 0.486
The Pvalue using a Pvalue calculator from Zscore is :
Pvalue = 0.313
α = 0.05
Pvalue > α ; We fail to reject the Null ; The is no significant evidence to conclude that mean is greater than 22

Bryce puts $100.00 into an account to use for schopl expenses. The account earns 3%
interest, compounded annually. How much will be in the account after 7 years?
Help!!!
Answer:
A = $122.99
Step-by-step explanation:
A = P + I where
P (principal) = $100.00
I (interest) = $22.99
First, convert R as a percent to r as a decimal
r = R/100
r = 3/100
r = 0.03 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 100.00(1 + 0.03/1)(1)(7)
A = 100.00(1 + 0.03)(7)
A = $122.99
Therefore:
The total amount accrued on a principal of $100.00 at a rate of 3% per year compounded 1 time per year over 7 years is $122.99.
Can someone help me with this I need both area and perimeter
Answer:
Step-by-step explanation:
NO I FONY FEEL LIKE IT
Perminter= P
Area= A
How to calculate the P: the p of this shape is pretty much easy to solve. Finding a P of a shape, you need to add all the sides up. So you just need to add 9+6+2+5+5+5+2+6. Remeber to double check that you got all the sides. Anothor equation you can do is (6x2) + (5x3)+(2x2)+9. Just pick a equation to do and you get the answer
how to caculate the A: Caucalating the A of this shape is actually a little hard. There is two ways to solve this but the second way to me is kinda hard. The first way is two divide this shape into rectangles and squares. So I dived it like this ( look at the image below). To calculate the area of a rectangle is to mutiply lengh by width. So first I will need to multiply 9x6 to find the first area of the rectangle. Then I have to multiple 5x5 to find the area of the second square. Then I just have to add the answer of the first answer to the second answer is 54+25.

prisim a and prisim b have the same volume. which could be the dimensions of prisim b?
Answer:
length = 4 feet
width = 4 feet
height = 10 feet
Step-by-step explanation:
8x4x5 = 160
4x4x10 = 160
Answer:
length = 4 feet
width = 4 feet
height = 10 feet
Step-by-step explanation:
First we must find the volume of prism A
Assuming that the prism is a rectangular prism we can easily calculate the volume by multiplying the length by the width by the height
So V = 8 * 4 * 5
8 * 4 = 32
32 * 5 = 160
Hence, the volume of prism a is 160ft²
The question states that the volume of prism A is the same as the volume of prism B. Given that information we want to find the possible dimensions of prism B such that volume of prism A = volume of prism B.
We can do this by find the volume of each answer choice ( again, assuming that their rectangular prism )
For the first answer choice
4 * 4 * 10 = 160
160 = 160 however lets check the other answer choices.
For the second answer choice:
5 * 4 * 7 = 140
140≠160 therefore the second answer choice is not correct
For the third answer choice
8 * 4 * 6 = 192
192 ≠ 160 therefore the third answer choice is not correct
For the fourth answer choice
I can't see the dimensions, however we already know that the answer is the first answer choice.
