The length of a rectangle is five more than three time its width. The perimeter of a rectangle is 234. What is the width of the rectangle
Answer:
28 units
Step-by-step explanation:
Given data
Let the width be x
The length is =3x+5
Perimeeter= 234
The expression for the perimeter is
P=2L+2W
Substitute
234= 2*x+2(3x+5)
234= 2x+6x+10
Collect like terms
234= 8x+10
234-10= 8x
224=8x
x= 224/8
x=28
Hence the width is 28 units
The base angles of an
isosceles triangle
Measure (2x+40)° and
(5x+16)". find x and the
Measure of both angles.
Answer:
71
93.5
x=15.5
Step-by-step explanation:
(2x+40)+(5x+16)+(x)=180
you have to put all the measures together and equal it to 180. when it comes to triangles, all the angles added together are equal to 180.
now solve the equation and you should get this:
x=15.5
the next step is to solve the give equations separately:
2(15.5)+40=71
5(15.5)+16=93.5
(15.5)=15.5
now to check the work, you have to add all the measures that were just calculated:
71+93.5+15.5=180 so check!

A recent study sought to determine if exercising after studying for an exam may help retain information. The 150 student volunteers that participated in the study were randomly assigned to three groups. All students were given a picture memory task that they studied for 15 minutes. After studying, one of the groups was instructed to exercise for 30 minutes immediately after studying. A second group was instructed to wait 1 hour after studying and then exercise for 30 minutes. The third group was instructed to not exercise after studying. The next day all 150 student volunteers were given a test to determine how well they could remember what they studied. Here are the results:
Answer:
The correct answer is (A).
Step-by-step explanation:
Because the data came from 3 groups in a randomized experiment, the appropriate test is a chi-square test for homogeneity.

Good art is art that allows you to enter it from a variety of angles and to
emerge with a variety of views."" what is you insights about this quotes?
Answer:
Step-by-step explanation:
My insight on this quote is that a good piece of art can tell various stories. Maybe there are various characters in the art and each on shows different actions and emotions. Or maybe the art is abstract and the emotions that it triggers in a person can tell a story all on its own. In a way these various angles are the different ways that the art makes us feels that allows us to view it in such a way. Yet these views can change if we look at the art in a different perspective.

Write the polnt-slope form of the equation of the line passing through the points (-5, 6) and (0, 1).
y- 6 = 1(x + 5)
y+6= -1(x - 5)
y- 6 = -1(x + 5)
y+ 6 = 1(x - 5)
Answer:
y - 6 = -1 (x+5)
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1} \\[/tex]. Substitute the x and y values of (-5,6) and (0,1) into the formula and simplify like so:
[tex]m = \frac{(1)-(6)}{(0)-(-5)} \\m = \frac{1-6}{0+5} \\m = \frac{-5}{5} \\m = -1[/tex]
So, the slope of the line is -1.
2) Now we have enough information to write the equation of the line in point-slope form. Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute real values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope of the line, substitute -1 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of (-5, 6) in those places as well. This gives the following equation and answer:
[tex]y-6 = -1(x+5)[/tex]

y= 5x - 9; domain = { 1,3,7 }
what is the range values?
Answer:
Step-by-step explanation:
range = [-4,6,26]
Step-by-step explanation:
y = 5x - 9.....domain = [1,3,7]....the domain is ur x values, and I am assuming ur looking for the y values that go with the x ones
y = 5x - 9.....when ur domain (ur x) = 1
y = 5(1) - 9
y = 5 - 9
y = -4
y = 5x - 9...when ur domain (x) = 3
y = 5(3) - 9
y = 15 - 9
y = 6
y = 5x - 9...when ur domain(x) is 7
y = 5(7) - 9
y = 35 - 9
y = 26
so ur range (ur y valus) = [-4,6,26]
Doug's teacher told him that standardized score (s-score) for his mathematics exam, as compared to the exam scores of other students in the course, is 1.20.
Full question:
Doug's teacher told him that the standardized score (z-score) for his mathematics exam, as compared to the exam scores of other students in the course, is 1.20. Which of the following is the best interpretation of this standardized score?
Doug's test score is 120.
Doug's test score is 1.20 times the average test score of students in the course.
Doug's test score is 1.20 above the average test score of students in the course.
Doug's test score is 1.20 standard deviations above the average test score of students in the course.
None of the above gives the correct interpretation.
Answer:
Doug's test score is 1.20 standard deviations above the average test score of students in the course.
Explanation:
Z scores are also known as standardized scores or normal scores or standardized variables. Z scores are used to standardize raw data in order to give them a uniformity or standard that allows for easier comparison of data values. For us to calculate a z-score as was done in Doug's test score, we simply subtract the mean from the raw data score and we divide the answer by the standard deviation.
River C is 400 miles longer than River D. If the sum of their lengths is 5560 miles, what is the length of each river?
Answer:
River D - 2580 miles
River C - 2980 miles
Step-by-step explanation:
Let the length of River D be represented with x
length of river C = 400 + x
total length of both rivers = 5560
x + 400 + x = 5560
2x + 400 = 5560
collect like terms
2x = 5560 - 400
2x = 5160
divide both sides of the equation by 2
x = 5160 / 2
x = 2580
length of river c = 400 + 2580 = 2980

if given a radius of 6mm, what is the diameter?
if given a diameter of 22ft, what is the radius?
Answer:
If the radius is 6mm, the diameter is 12mm.
If the diameter is 22 ft, the radius is 11 ft.
Step-by-step explanation:
1st one) When you try to find the diameter of any circle, and you already have the radius, you need to multiply it by two (double it)
6 x 2 = 12mm
2nd one) Then to do the opposite, you need to divide the diameter by 2.
22/2 = 11 ft
Hope this helped :)
