Choose all answers that apply.
A. square root of 2, square root of 3, square root of 4
B. square root of 8, 3, square root of 17
C. 5, 6, 8
Answer: choice B
Explanation: Go through each answer choice and try the Pythagorean theorem to see if it works. This is because a right triangle’s side lengths are described by the Pythagorean theorem. one side^2 + second side^2 = longest side^2. In a right triangle, this equation will be true. Let me show you what I mean
For answer choice A:
(root 2)^2 + (root 3)^2 = (root 4)^2
2 + 3 = 4
5 = 4
5 does not equal 4. Therefore it cannot be A.
For answer choice B:
(root 8)^2 + (3)^2 = (root 17)^2
8 + 9 = 17
17 = 17
this is true! therefore this is a right triangle and it’s B
Dimensions √17, 3, and √8 are the dimension of the right triangle. Thus, the correct option is B.
What is a Pythagoras theorem?If the dimension satisfies the Pythagorean equation, then the triangle is a right-angle triangle.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side. The Pythagoras theorem formula is given as,
H² = P² + B²
Let's check the second option, then we have
(√17)² = 3² + (√8)²
17 = 9 + 8
17 = 17
Thus, the correct option is B.

what is a term called that has no variable? constant or coefficient
Answer: It is constant
Answer:
Constant.
Step-by-step explanation:
Constants are any number that does not have a variable such as x or y, so if they do not have variables, there definitely would not have coefficients. Examples of constants are 2, 5 and 67.
Coefficients are like the 2 in 2x, the 5 in 5y and the 67 in 67xy. All of these numbers have a variable.
Factor the binomial: x^2 - 8x

A shoe store pays 1980$ a month for rent. The average profit on each pair of men's shoes is $25, and the average profit on each pair of wemons shoes is $65. They usually sell 3times as many pairs of wemons shoes as men's.How many pairs of shoes of each type of shoe must the store sell each month to pay the rent?
Answer:
Number of men's shoes = x = 9 shoes
Number of women's shoes = y = 27 shoes
Step-by-step explanation:
A shoe store pays 1980$ a month for rent. The average profit on each pair of men's shoes is $25, and the average profit on each pair of wemons shoes is $65. .How many pairs of shoes of each type of shoe must the store sell each month to pay the rent?
Number of men's shoes = x
Number of women's shoes = y
The system of equations is given as:
$25 × x + $65 × y = $1980
25x + 36y = $1980..... Equation 1
They usually sell 3times as many pairs of wemons shoes as men's
y = 3x
25x + 65y = $1980..... Equation 1
25x + 65(3x) = 1980
25x + 195x = 1980
220x = 1980
x = 1980/220
x = 9 shoes
y = 3x
y = 3(9)
y = 27 shoes
Number of men's shoes = x = 9 shoes
Number of women's shoes = y = 27 shoes

C)$13,188
D)$13,458
The Owen family expect to pay, per year, to raise the child from birth to 18 years of age is $18203.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that,
Cost of raising a child in 2 years
Birth to 5 years old $65,250
5 to 18 years old $139,560
4 y Public college $24,382
4 y private college $98,470
Here, total money = 65,250+139,560+24,382+98,470
= $327662
Money to raise in a year = 327662/18
= $18203
Therefore, the Owen family expect to pay, per year, to raise the child from birth to 18 years of age is $18203.

A towel set consisting of a towel and 6 napkins cost rupees 200 if the cost of each napkin is rupees 95 less than the cost of the towel what is the cost of the towel
Answer:
The towel costs 110 rupees
Step-by-step explanation:
Let n be napkins, and t be towels. Then:
6n+t=200
and
n=t-95
So:
6(t-95)+t=200
7t-570=200
7t=770
t=110....................
Among the set of towels and napkins, the cost of the towel will be equal to 110 rupees.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the data given in the question,
Assume that n is for napkins, and t is for towels then,
6n + t = 200 (i)
Also,
The cost of the napkin is rupees 95 less than the towel,
n = t - 95 (ii)
Use equations (i) and (ii)
6(t-95)+t=200
7t-570=200
7t=770
t=110
