What expression represents the length of one side of the square?
Answers
Answer:
The expression representing length is (x+1).
Step-by-step explanation:
Area of square = [tex]1+2x+x^2[/tex]
We need to find length of square
We know that: [tex]Area\:of\:Square=(Length)^{2}[/tex]
Putting values and finding length
[tex]Area\:of\:Square=(Length)^{2} \\\\1+2x+x^2=(Length)^{2}\\(Length)^{2} = x^{2} + x +x +1\\(Length)^{2} = x( x+1) +1 (x +1)\\(Length)^{2} = (x+1)^{2}\\Length = (x+1)[/tex]
So, the expression representing length is: (x+1)

2n+2n+4=88
4n+4=88
4(n+1)=88
n+1=88/4
n+1=22

Timothy walks from home to a mailbox. After
walking 15 min, he puts a letter in the mailbox.
Then he walks home at the same speed. The
graph shows his distance from the mailbox
as a function of time. What is his walking speed?
A 280 ft/min © 260 ft/min
B 270 ft/min
D 250 ft/min
Answers
Answer:
D. 250 feet per minute
Step-by-step explanation:
According to this question, Timothy walks at constant speed. From Physics we know that speed is the magnitude of velocity and is determined by the following definition:
[tex]v = \frac{\Delta x}{\Delta t}[/tex] (1)
Where:
[tex]\Delta x[/tex] - Distance between home and mailbox, measured in feet.
[tex]\Delta t[/tex] - Travel time, measured in minutes.
[tex]v[/tex] - Walking speed of Timothy, measured in meters per second.
The distance is represented by the vertical axis of the graph, whereas the travelling time is from the horizontal axis.
If we know that [tex]\Delta x = 3,750\,ft[/tex] and [tex]\Delta t = 15\,min[/tex], then the walking speed of Timothy is:
[tex]v = \frac{3,750\,ft}{15\,min }[/tex]
[tex]v = 250\,\frac{ft}{min}[/tex]
The walking speed of Timothy is 250 feet per minute. Hence, the right answer is D.

In a second period class, 37.5% of students like to bowl. in a fifth period class, 12 out of 29 students like to bowl. in which class does a greater fraction of the students like to bowl?
Answers
The fifth period class has a greater fraction of students that like to bowl.
Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, -3/4, 0.3, or 3/10.
Here we have,
In second period, 37.5% students like to bowl
∴, 37.5% = 37.5/100
= 375/1000
= 0.375 students like to bowl in second period
And in fifth period, 12 students out of 29 like to bowl
Therefore, 12/29 = 0.413 students like to bowl in fifth period
Hence, on comparison
0.375 < 0.413
= 375/1000 < 12/29
Thus, fifth period class has a greater fraction of student that like to bowl as compared to second period class.

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?
f(150) represents the average number of days houses stay on the market before being sold for $150,000.
Houses sell on the market for an average of $150,000 and stay on the market an average of 150 days before being sold.
Houses sell for an average of $150,000.
f(150) indicates houses stay on the market an average of 150 days before being sold.
Answers
Answer:
This is the average number of days the house stayed on the market before being sold for $150,000.
Step-by-step explanation:
f(p) is defined as the average number of days a house stays on the market before being sold for price p (given in $1000).
We want f(150); this means p=150. Since p is in thousands of dollars, this means the price of the house was $150,000.
This means f(150) is the average number of days the house stayed on the market before being sold for $150,000.
Answer:
The statement that best describes f(150) is D
Step-by-step explanation:
D. f(150) indicates houses stay on the market an average of 150 days before being sold.
Because houses stay on the market for 150 days before being sold.
