Which value must be added to the expressionx2+16x to make it a perfect-square trinomial?
Answer:
Step-by-step explanation:
Please write x^2+16x or x²+16x to indicate the exponentiation.
To rewrite x²+16x as a perfect square trinomial:
1) Take half of the coefficient of x, that is, half of 16, which is 8
2) Square this result: 8² or 64
3) Starting with x²+16x again, add 64 and then subtract 64 to get a trinomial expression equivalent to x²+16x:
x²+16x + 64 - 64
4) Rewrite the first three terms as the square of the binomial x + 8:
(x + 8)² - 64
Here (x + 8)² is a perfect square trinomial.
Answer:
The answer is C.) 64 on edge.
If Casey deposits $16 into his lunch account each week, how much will be deposited in 5 weeks? If Casey decides to buy lunch for his friend at $3.00 per lunch, how many lunches can he buy his friend?
Answer:
The exact number would be 26.66666667 but it would be 26.
Step-by-step explanation:
Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.

The sum of two numbers is no more than 28. Let x represent the first number, and let y represent the second number. Which inequality represents this situation?
A) y
B) y<_x+28
C) x+y <28
D) x+y<_28
Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
in a stick of chalk carbon is 3 g what is the weight of the chalk stick
Answer:
Hence the weight of chalk stick is 25 g.
Explanation:
Let the weight of a stick be x gm.
12% of x=3
(12/100)*x=3
x=3*(100/12)=25 g
Answer:
weight of chalk = 25gStep-by-step explanation:
let chalk contains 10x calcium, 3x carbon, 12x oxygen.
percentage of carbon in the chalk:
= 3x x 100
10x + 3x + 12x
= 3x ( 100 )
25x
= 3 (4)
= 12%
Now, we know that carbon has 12% of chalk.
weight of carbon = 12% x weight of chalk. ------------- equation
plugin values into the equation:
3 = 12% (weight of chalk)
3 = 12 (weight of chalk)
100
12 (weight of chalk) = 3
100
weight of chalk = 3 (100)
12
weight of chalk = 25g
The distribution of durations for which apartments remain empty after the resident moves out for one property management company over the past 10 1010 years was approximately normal with mean μ = 85 μ=85mu, equals, 85 days and standard deviation σ = 29 σ=29sigma, equals, 29 days. The property management company tags the files of the apartments that were empty for the shortest 5 % 5%5, percent of durations to have priority cleaning the next time their residents move out
A part of the question is missing which is;
What is the minimum duration for which an apartment remained empty for the company to update the kitchen appliances? Round to the nearest whole number.
Answer:
133 days
Step-by-step explanation:
We are given;
Population mean; μ = 85 days Population standard deviation; σ = 29 days
significance level; α = 5% = 0.05
Critical value of z at significance level of 0.05 = 1.645
Now, formula for z-score is;
z = (x - μ)/σ
Where x is the minimum duration for which an apartment remained empty for the company to update the kitchen appliances.
1.645 = (x - 85)/29
(1.645 × 29) = x - 85
47.705 = x - 85
x = 85 + 47.705
x = 132.705
x ≈ 133 days
Answer: 37 days

Jung-Soon has $25 to spend on prizes for a game at the school fair. Lip balm costs $1.25 each, and
mini-notebooks cost $1.50 each. Write a linear equation that can be used to determine how many of
each prize she can buy.
Answer:
1.25x + 1.5y=25
Step-by-step explanation:
let the number of lip balms that can be bought be x and the notebooks be y then their total cost is 1.25x + 1.5y. The total $25 there for the equation becomes 1.25x + 1.5y=25.
The required linear equation can be used to determine how many of each prize she can buy is 1.2x + 1.50y = 25.
Given that,

Rewrite each geometry formula using function notation. Use the same variables as the formula in your function. Evaluate each function when r=5 feet. Do not round; write answers in terms of pi, if necessary. Explain the meaning of the result.
a. Diameter, d=2r
The formula using function notation is _______; The value when r=5 is _______; The diameter of the circle is ______ feet when the radius is ________ feet.
b. Area, A=pi x r^2
The formula using function notation is _______; The value when r=5 is _______; The area of the circle is ______ feet when the radius is ________ feet.
c. Circumference C=2 x pi r
The formula using function notation is _______; The value when r=5 is _______; The Circumference of the circle is ______ feet when the radius is ________ feet.
Answer:
A) d(r) = 2r
Value when r = 5 is 10 ft.
diameter is 10 ft when the radius is 5ft
B) A(r) = πr²
Value when r = 5 is 25π ft²
Area is 25π ft² when radius is 5 feet
C) C(r) = 2πr
Value when r = 5 is 10π
Circumference is 10π when radius is 5 feet
Step-by-step explanation:
A) Using function notation, since d = 2r
d(r) = 2r
d(5) = 2(5)
d(5) = 10 feet
This means that the diameter is 10 ft when the radius is 5ft
B) Area = πr²
In function notation, its;
A(r) = πr²
When radius is 5 feet,
Area is; A(5) = π(5²) = 25π
It means Area is 25π ft² when radius is 5 feet
C) Circumference is 2πr
In function notation, it's;
C(r) = 2πr
When r = 5 feet,
Circumference is;
C(5) = 2π(5)
C(5) = 10π
The gum of two number is 37. Find the number if
lone number is 1 more than twice the other.
a = 25
b = 12
Step-by-step explanation:Hi there !
a + b = 37
a = 2b + 1
replace a
(2b + 1) + b = 37
3b = 37 - 1
3b = 36
b = 36 : 3
b = 12
a = 2×12 + 1
a = 24 + 1
a = 25
a + b = 37
25 + 12 = 37
37 = 37 (true)

A movie production company was interested in the relationship between the budget to make a movie and how well that movie was received by the public. The company collected information on several movies and used it to obtain the regression equation y = 0.145x+0.136, where x represents the budget of the movie (in millions of dollars) and y is the predicted score of that movie (in points from 0 to 1). Which statement best describes the meaning of the y-intercept of the regression line?
When the score of a movie is 0 points, the predicted budget is $0.
When the score of a movie is 0 points, the predicted budget is $0.136 million.
When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.
When the budget of a movie is $0, the predicted rating is 0.145 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.
Answer:
Pretty sure it's (C), although I am unable to check. --> IT IS C I GOT 100%
"When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0."
The y intercept is the starting "points", which is .136. Basically the company uses the equation to figure out how much money they got from a movie and how it increases as the budget increases. They make money off points.
So when there's no budget or a budget less than a million, thats what they earn in points.
Which is, .136 ; this means when theres no budget, they are expected to start with .136 points. (Probably cuz they're a cool company or something)
========================
If you're looking for a question that asks "What is the predicted score of a movie that has a $5 million budget?", its (C), .861
If you're looking for a question that asks "What is the predicted score of a movie that has a $250,000 budget?", it's (B) 0.17225 points
[THIS PART IS SEPARATE FROM THE ORIGINAL QUESTION]
========================
ED2021
The interpretation of a given situation is required.
When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.
The regression equation is
[tex]y=0.145x+0.136[/tex]
where,
[tex]y[/tex] = Predicted score of that movie
[tex]x[/tex] = Budget of movie in millions of dollars
The y intercept is the value of the function when [tex]x=0[/tex]. So,
[tex]y=0.145\times 0+0.136\\\Rightarrow y=0.136[/tex]
When [tex]x=0[/tex] this means the budget of the movie is 0 million dollars.
This is not meaningful.
So, the correct interpretation of the y intercept is When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.

What is the slope for Δy = 27, Δx = –8
Answer:
The slope is - 3 3/8
Step-by-step explanation:
Mathematically, we can calculate the slope m using the formula;
m = Δy/Δx
From the question;
Δy = 27 and Δx = -8
The slope will thus be;
m = 27/-8 = - 3 3/8
