Answer: 5 + 3x ≤ 20; 5
Step-by-step explanation:
at most means not more than(less or equal to),which use the symbol ≤. Let x be the hour that Max rent.
5 + 3x ≤ 20
3x ≤ 15 [Subtract 5 from both sides.]
x ≤ 5 [Divide 3 from both sides.]
Any value less than or equal to 5 will be satisfies the inequality.
Describe and correct the error a student made in identifying the common difference of the following sequence.
29, 22, 15, 8, 1, ...
Given:
The sequence is 29, 22, 15, 8, 1, ...
To find:
The common difference.
Solution:
We have,
29, 22, 15, 8, 1, ...
It is an AP.
First term : [tex]a_1=29[/tex]
Second term : [tex]a_2=22[/tex]
Now,
Common difference : [tex]d=a_2-a_1[/tex]
[tex]d=22-29[/tex]
[tex]d=-7[/tex]
Therefore, the correct common difference is -7.
Note: Here calculation by student is not given, so we cannot find the error of the student.
Write the equation of a line through points (5, 5) and (1, 0) in point-slope form.
Help soon pls :)
Answer:
Step-by-step explanation:
Find the slope of the line between (5,5)and (1,0) using m=(y2-y1)/(x2-x1)
which is the change of y over the change of x.
m=5/4
Use the slope 5/4 and a given point (5,5) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=(y2-y1)/(x2-x1)
y-5=5/4*(x-5)
Simplify the equation and keep it in point-slope form y-5=5/4*(x-5)
Solve for y.
y=5x/4-5/4
Reorder terms.
y=5/4 x-5/4
List the equation in different forms.
Slope-intercept form: y=5/4 x-5/4
Point-slope form: y-5=5/4*(x-5)

plsss I'll mark Brainlest
Answer:
For class A, the test scores were closer togther so that means more students most likely scored the smae score mutiple times. I think this because the box on the box plot is not spread out like class B.
For class B, the scores varied more so the box plot has to be spread out over more values. Because of the box plot, we can see that Class B had the highest test score compared to class A.

What is the approximate area of the shaded region under the standard normal curve below? Use the portion of the standard normal table to help answer the question. A normal curve with a peak at 0 is shown. The area under the curve shaded is negative 1 to positive 2. Z Probability 0. 00 0. 5000 1. 00 0. 8413 2. 00 0. 9772 3. 00 0. 9987 0. 16 0. 68 0. 81 0. 84.
The area under the curve shaded is -1 to 2 is 13.59%.
The z score is a measure used in statistic to determine by how much standard deviations the raw score is above or below the mean.
If the raw score is greater than the mean then the z score is positive but if the raw score is less than the mean then the z score is negative.
What is the formula for the z score?
The formula of z score
[tex]Z=\frac{x-\mu}{\sigma}[/tex]
[tex]\mu=mean[/tex]
[tex]\sigma=standard deviation[/tex]
x=raw score
From the normal distribution table,
Area between z = -2 and z =-1 is given by
P(-2 < z < -1) implies that P(z < -2) - P(z < -1) that is
P(z < -2) - P(z < -1) = 0.1587 - 0.0228
P(z < -2) - P(z < -1) = 0.1359
P(z < -2) - P(z < -1) = 13.59%
Therefore we get the area under the curve shaded is -1 to 2 is 13.59%.

2/5x + 4 = 1/5x + 8 what does x equal
Answer:
x=20
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
2/5x + 4 = 1/5x + 8
(subtract 1/5x from both sides)
1/5x + 4 = 8
(subtract 4 from sides)
1/5x = 4
(multiply by 5 from both sides of the equation to isolate x)
x = 20
Frank traveled 5.3 kilometers from work to home in 30-minutes. Which of the following values is closest to the average speed, in miles per hour?
Frank's average speed is the rate of the distance traveled and the time
Frank's average speed is 6.58 miles per hour
How to determine the average speedThe given parameters are:
Distance = 5.3 kilometers
Time = 30 minutes
The average speed is then calculated as:
Average speed = Distance/Time
Substitute known values
Average speed = 5.3km/30 minutes
Convert time to hours
Average speed = 5.3km/0.5 hour
Convert the distance to miles
Average speed = 3.29 miles/0.5 hour
Evaluate the quotient
Average speed = 6.58 miles per hour
Hence, Frank's average speed is 6.58 miles per hour

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!
Answer:
E, 3/2
Step-by-step explanation:
First, say that the numerator is 2^2001 * 3^2001 * 3^2, so that the powers will align. Then, we can combine 2^2001 and 3^2001 for 6^2001. If we ignore the 3^2, we get 6^2001/6^2002, which simplifies to 1/6. If we multiply 9 (which is 3^2) to 1/6, we get 9/6=3/2. This is a pretty tough question. Hopefully this helps!
What are all the things dilations do in geometry?
Answer:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.

A Ferris wheel at Kone Island has a diameter of 63 feet.
Which equation can be used to find its circumference, Cin feet?
diameter 63 feet
O C = 63 x II
O C = 31 x II
O C = 2 x II x 63
O C = 2 x II x 31
The circumference of the Ferris wheel is the product of the diameter and [tex]\pi[/tex]
The circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]
How to determine the circumference equationThe circumference of a circle, when the diameter is given is calculated using the following equation
C = [tex]\pi[/tex]d
The diameter of the Ferris wheel is given as:
d = 63 feet.
So, we have;
C = [tex]\pi[/tex] * 63
Rewrite as:
C =63 * [tex]\pi[/tex]
Hence, the circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]

What is the result of the construction shown?
A. Angle bisector
B. Copying an angle
C. Copying a line segment
D. Perpendicular bisector
Answer:
Option C: Copying an angle
Step-by-step explanation:
Angle bisector is a line through an angle that will split that angle to 2 equal angles. Thus, option A is wrong as no angle is being split.
Copying an angle involves reproducing a particular angle in another construction. The image shows us that there is an attempt to reproduce the perpendicular angle of 90°. Thus, option B is correct.
Copying a line segment involves creating the exact size of line in another construction. The image doesn't depict that. Thus option C is wrong.
Perpendicular bisector is when we draw a perpendicular line through a horizontal one to divide it into 2 equal parts. This is not the case here. Thus, option D is wrong.

45^2 + B^2 = 500^2
Subtract 45^2
B^2 = 500^2 - 45^2

A number line ranging from minus 660 to plus 660. Tick marks are every 60 units. A point labeled Samantha is located at two tick marks to the right of zero. A point labeled Ryu is located at 8 tick marks to the left of zero.
How many feet apart are Ryu and Samantha on the number line?
Enter your answer in the box.
For Samantha, 2 tick marks east is 120 units east because 1 tick is 60 units.
For Ryu, 8 tick marks west is 480 units west because 1 tick is 60 units.
They are walking to form a line. Just add their distances from 0.
120 + 480 = 600.

Step-by-step explanation:
If two polygons are congruent, then they have the same area.
Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. We indicate that angles are congruent by putting the same number of slash marks through each angle.
