Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. n2+n
Answer:
Perfect square trinomial: [tex]n^2+n+\dfrac{1}{4}[/tex]
Binomial squared: [tex]\left(n+\dfrac{1}{2}\right)^2[/tex].
Step-by-step explanation:
The given expression is [tex]n^2+n.[/tex]
Here coefficient of n is 1.
Now, find square of half of coefficient of n.
[tex]\left(\dfrac{1}{2}\times 1\right)^2=\dfrac{1}{4}[/tex]
Now, add [tex]\dfrac{1}{4}[/tex] in the expression to make it perfect square trinomial.
[tex]n^2+n+\dfrac{1}{4}[/tex]
[tex]\Rightarrow n^2+n+\left(\dfrac{1}{2}\right)^2[/tex]
[tex]\Rightarrow \left(n+\dfrac{1}{2}\right)^2[/tex] [tex]\because (a+b)^2=a^2+2ab+b^2[/tex]
Therefore, perfect square trinomial is [tex]n^2+n+\dfrac{1}{4}[/tex] and binomial squared is [tex]\left(n+\dfrac{1}{2}\right)^2[/tex].
Graph the line with slope 1 passing through the point (5,4) .
Answer:
y=x-1
is the line equation
Step-by-step explanation:
As we know that general equation of line is given by
y=mx + c
m is the slope and c is is y intercept
Know m = 1 and point (x,y) as (5,4)
So plug in the values and solve for c
4=1*(5)+c
c=-1
So equation of line is
y=x-1
Which equation correctly shows the multiplication of the means and extremes in the proportion 7.2∕9.6 = 21.6∕28.8?
Answer:
7.2 × 28.8 = 9. 6 × 21.6
Step-by-step explanation:
Given the equation:
7.2∕9.6 = 21.6∕28.8
The equation which provides the multiplication of the means and the extremes in the equation provided above can be obtained through cross multiplication of the two ratios or proportion.
(7.2 / 9.6) = (21.6 / 28.8)
L. H. S = R. H. S
(numerator of L. H. S * denominator of R. H. S) = (denominator of L. H. S * numerator of R. H. S)
Hence, we have ;
7.2 × 28.8 = 9. 6 × 21.6

Sarah and John are running clockwise around a circular track with radius 25 meters. They start at the same position, and Sarah runs at 2.7 m/s while John runs at 2.2 m/s. How far away from their starting point are they when Sarah catches up and passes John for the first time after the start?
Answer:
62.8 m
Step-by-step explanation:
The length of one lap is ...
C = 2πr = 2π(25 m) = 50π m ≈ 157.08 m
Sarah is gaining ground on John at the rate of 2.7 m/s -2.2 m/s = 0.5 m/s. So it will take Sarah ...
157.08 m/(0.5 m/s) = 314.16 s
to run 1 lap farther than John does.
It takes Sarah ...
157.08 m/(2.7 m/s) = 58.18 s
to run 1 lap, so in the time it takes her to catch John, she will have run ...
314.16 s/(58.18 s/lap) = 5.4 laps
She (and John) will be 0.4 laps from their start when they meet again. That distance is ...
(0.4)(157.08 m) = 62.8 m
Sarah will catch and pass John 62.8 meters from their starting position.

Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number of shirts sold. After selling a certain number of shirts, Benito uses some earnings to buy more materials and then increases the price of the shirts. Which of the following is true? a. The domain of the function is {x | x is a real number greater than or equal to 0}. b. Benito increases the price after selling 50 shirts. c. The x-intercept represents the shirts he has to sell before making a profit. d. The y-intercept represents the cost of one T-shirt.
Answer:
a. The domain of the function is {x | x is a real number greater than or equal to 0}.
Step-by-step explanation:
The graph shows
1) the domain of the function {x | x is a real number greater than or equal to 0}
The domain of the function of the graph is obtained by the x - values which range from 0-11 . Thus they are equal or greater than zero.
2) the y- intercept shows the profit that is made by selling a certain number of shirts.
3) the x- intercept shows the number of shirts sold
4) Benito increases the price at least after the profit of $25 is made because we see from the graph that there is a loss of $10 if one shirt is sold separately and the dot on the eight appears around $ 25.
Only option a is true.
Graphs are used to show the relationship between related quantities.
From the given options, the true statement is:
c. The x-intercept represents the shirts he has to sell before making a profit.
From the given graph, we have the following observations.
1. The domain of the graph is [tex]x \ge 2[/tex]
The corresponding y-values are negative for x = 0 and 1.
Because the graph represents the profit function, no value of x must correspond to a negative y-value.
Hence, (a) is false
2. It is impossible to say that his price increases, after selling 50 shirts
The y values show profit from shirts; not the price of shirts
Hence, (b) is false
3. The x-intercept indicates when he'll make a profit
The graph crosses the x-axis at x= 2.
This means that, he has to sell at least 2 shirts, before making a profit.
Hence, (c) is true
4. The y-intercept is the cost of 1 shirt
The y values show profit from shirts; not the price of shirts
Hence, (d) is false
Based on the above analysis, we can conclude that (c) is true

A store sells paint sets. Each paint set costs the same amount. During a sale, the store reduces the price of each paint set by $1.50. Logan spends
$13.47 on 3 paint sets at the sale price.
What was the price of I paint set before the sale?
Answer:
the price of I paint set before the sale was $5.99
Step-by-step explanation:
Selling price of 3 paint sets = $13.47
To get selling price of 1 set
we divide both LHS and RHS by 3
Selling price of 3/3 = 1 paint sets = $13.47/3 = $4.49
Thus, selling price of 1 paint set after sale is $4.49
Given that
the store reduces the price of each paint set by $1.50
Let the price before sale be x
selling price of 1 paint set after sale = price before sale - $1.50
$4.49 = $x - $.150
$x = $4.49 + $1.50 = $5.99
Thus, the price of I paint set before the sale was $5.99
The area of a rectangular wall of a barn is 16 square feet. Its length is 4 feet longer than twice its width. Find the length and width of the wall of the barn.
Answer:
width = 2 ft
length = 8 ft
Step-by-step explanation:
area = L x W
area = 16 ft^2
width = x
length = 2x+4
width = 2 ft
length = 2(2)+4
length = 4+4
length = 8 ft
area = 8 x 2 = 16 ft^2
Yaneev thinks of a number y. He subtracts three from the number, then doubles it. Then he subtracts three again, and doubles the number again. The result is his original number y. What is y?
Answer: y=6
Step-by-step explanation:
The given number is y.
According to the question,
Step 1 . subtracts three from the number (y-3), then doubles it
i.e. Final number = 2(y-3)
Step 2 . subtracts three again i.e. (2(y-3)-3), and doubles the number again
i.e. Final result = 2(2(y-3)-3)
If the result is his original number y, then
2(2(y-3)-3) =y
⇒ 2(2y-6-3)=y [ using distributive property]
⇒ 2(2y-9)=y
⇒ 2(2y)-2(9)=y [ using distributive property]
⇒ 4y -18=y
⇒ 4y -y= 18
⇒ 3y= 18
⇒ y= 6 [Divide both sides by 3]
Hence, y=6
Answer:
y = 6
Step-by-step explanation:
here, lets plug it into the equation.
((y - 3)2) - 3)2 = y
((6-3)2) - 3)2 = 6
6-3 = 3 * 2 = 6 - 3 = 3 * 2 = 6
a rescue company determined that 90 out of 100 calls they received were true emergencies. which describes the fraction of their calls that were true emergencies.
Step-by-step explanation:
It is given that,
A rescue company determined that 90 out of 100 calls rescue company determined that 90 out of 100 calls. We need to find the fraction of their calls that were true emergencies.
Fractions can be written as true value on the denominator and the part of it on the numerator.
The required value is : [tex]\dfrac{90}{100}=\dfrac{9}{10}[/tex]
So, (9/10) describes the fraction of their calls that were true emergencies.
Michael paid $16.40 for 20.5 centimeters of wire. Find the unit price in dollars per centimeter. If necessary round your answer to the nearest cent.
Answer:
$0.80
Step-by-step explanation:
$16.40 ÷ 20.5 = 0.80
You can check your work by doing :
20.5 cm of wire × $0.80 = $16.40
The unit price of the wire which Michael bought 20.5 cm for $16.40 is $0.8.
What is The Unit price?The price of a product offered in more or fewer than one unit is referred to as the unit price. The "unit pricing" of a food package informs you of the price per pound, quart, or another unit of weight or volume. Normally, it is displayed underneath the food on the shelf. The item price (total price) and unit price (unit price) for the food item are both displayed on the shelf tag. When shoppers are taught how to use unit price information in supermarkets, research reveals that they can save about 17–18%, but over time, this number decreases.
Given:
The price for the length of 20.5-centimeter wire, a = $16.40,
Calculate the price of 1 cm wire by dividing the total price by the length of the wire,
So unit price = 16.40 ÷ 20.5
Unit price = $0.8
Therefore, the unit price of the wire is $0.8.

Two cyclists, 40 miles apart, start riding toward each other at the same time. One cycles 3 times as fast
as the other. If they meet 2
hours later, what is the speed (in mi/h) of the faster cyclist?
Answer:
15 mph
Step-by-step explanation:
The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...
faster cyclist distance : slower cyclist distance = 3 : 1
Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.
That distance took 2 hours for the faster cyclist, so the speed was ...
speed = distance/time = 30 mi/(2 h) = 15 mi/h
