Answer:
let, width be 'x'
perimeter of rectangle=2(length+width)
56=2(19+x)
56=38+2x
2x=56-38
x=18/2
x=9inches
so, the width of rectangle is 9 inches.

The circumference of a circle is 22π in. What is the area, in square inches? Express your answer in terms of π
Answer:
A = 121 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi*r
22 pi = 2 * pi *r
Divide each side by 2 pi
22 pi / (2 pi) = 2 pi r / (2pi)
11 = r
Now find the area
A = pi r^2
A = pi (11)^2
A = 121 pi in^2

Answer:
Y = 60 degrees and X = 12
Step-by-step explanation:
x+3 and 15 are congruent so x+3 = 15, 12+3 = 15 therefore x = 12
y = 60 vertically opposite angles are equal. :D
Answer:
x= 12
y= 60
Step-by-step explanation:
to find x we need to know that lines DC and AB are parallel, so they have the same length (I don't know if that is why they have the same length, but I know they do lol)
So you can make this equation and solve:
15=x+3
-3 -3
12=x
THEN, to find y angle A and C are vertical angles, so they are congruent (this is the reason why they have the same measure lol)
So, y=60 degrees :)
I hope this sorta helps lol :)
When the sum of 3 times a number and 4 is increased by 6, the result is 2 times a number decreased by 14. Determine whether each step is a correct step for writing and solving this equation by selecting Yes or No. A Write the equation 3n + 4 + 6 = 2n – 14. Yes No B Write the equation 3(n + 4) + 6 = 2(n – 14). Yes No C Combine like terms. Yes No D Subtract 2n from each side. Yes No E Add 10 to each side. Yes No F Subtract 10 from each side. Yes No
Answer:
A. Yes
B. No
C. Yes
D. Yes
E. No
F. Yes
Step-by-step explanation:
A Write the equation 3n + 4 + 6 = 2n – 14. Yes
B Write the equation 3(n + 4) + 6 = 2(n – 14). No
C Combine like terms. Yes
D Subtract 2n from each side. Yes
E Add 10 to each side. No
F Subtract 10 from each side. Yes
Solution:
sum of 3 times a number and 4 is increased by 6, the result is 2 times a number decreased by 14
Let the number = n
{(3 * n) + 4} + 6 = (2 * n) - 14
3n + 4 + 6 = 2n - 14
3n + 10 = 2n - 14
3n + 10 - 2n = 2n - 14 - 2n
n + 10 = -14
Subtract 10 from each side
n + 10 - 10 = -14 - 10
n = -24
Answer: A. Yes B. No C.Yes D. Yes E. No F. Yes

A 23.9 foot tall streetlight casts a shadow that is 17.7 feet long. How long is the shadow cast by a nearby parking meter that is 3.6 feet high?
Answer:
2.67 feet long
Step-by-step explanation:
Create a proportion where x is the length of the parking meter's shadow:
[tex]\frac{23.9}{17.7}[/tex] = [tex]\frac{3.6}{x}[/tex]
Cross multiply and solve for x:
23.9x = 63.72
x = 2.67
So, the parking meter's shadow is approximately 2.67 feet long
3-2i+8=23 can you solve this find what i equals
Answer:
i = -6
Step-by-step explanation:
3 - 2i + 8 = 23
3 + 8 - 2i = 23
11 - 2i = 23
11 - 11 - 2i = 23 - 11
-2i = 12
-2i ÷ -2 = 12 ÷ -2
i = -6
This scatter plot shows the relationship between the average weight and average heart rate for 11 different animals. The line of best fit is shown on the graph. Select True or False for each statement based on the graph.
Answer:
See below
Step-by-step explanation:
1) I would lean more toward false because most of the points aren't in a straight line
2) That is most likely true because the line of best fits appears to be hitting that point
3) That is false because point D is located on the line of best fit which means it isn't an outlier

Lisa went to the store to buy shirts and pants. Shirts
were $5 each and pants were $15 each. She can
spend a total of $135.
Write an equation to represent the situation. Let s
represent the number of shirts and p represent the
number of pants.
Answer:
In this question you got multipel answers.
If she buys as much pants as she can;
135 - (15.p) = 5.s
135 - (15.9) = 0
so now she has bought no shirts and 9 pants.
if she buys as much shirts as she can;
135 - (5.s) = 15.p
135 - (5.27) = 0
so now she has bought no pants and 27 shirts.
If she wants a shirt for each pants the equation would look something like this;
p=s=x
135 - (15.x) = 5.x
but with each pants she can buy three shirts, so 9 = 3.3
(7.15)+(6.5)= 105+30= 135
so now she has 7 pants and 6 shirts.

Round 19.798 to the nearest tens place.
Answer:
20
Step-by-step explanation:
Hope this helps!!!!
If it is tens its 20
If it ins tenth its 19.8
To round 19.798 to the nearest tenth consider the hundredths’ value of 19.798, which is 9 and equal or more than 5. Therefore, the tenths value of 19.798 increases by 1 to 8.
19.798 rounded to the nearest tenth = 19.8
Answer:
19.8
Step-by-step explanation:
I'm not sure if you mean "tens" or "tenths" so I assumed "tenths".
If it was "tens" then it would be 20.

find the mean median and mode. 63, 40, 51, 70, 36, 21, 51, 28, 19
The mean, median, and mode of the data will be 41.111, 40, and 51 respectively.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.
The data is given below.
63, 40, 51, 70, 36, 21, 51, 28, 19
Arrange the data in ascending order, then we have
19, 21, 28, 36, 40, 51, 51, 63, 70
Then the mean of the data is given as,
Mean = (19 + 21 + 28 + 36 + 40 + 51 + 51 + 63 + 70) / 9
Mean = 379 / 9
Mean = 42.11
The median of the data is the middle term of the data which is 40.
The mode is 51 because the number frequency of 51 is the highest.

Part A: Create a scatter plot to represent the data shown above. Sketch the line of best fit. Label at least three specific points on the graph that the line passes through. Also include the correct labels on the x-axis and y-axis. Part B: Algebraically write the equation of the best fit line in slope-intercept form. Include all of your calculations in your final answer. Part C: Use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
It is to be noted that the scatter plot that represent the above data is attached accordingly.
What is a scatter plot?A scatter plot is a graph in which the data of two variables are displayed along two axes, and any association is revealed by the pattern of the resultant dots.
Remember Scatter plot is a type of x-y graphX is the horizontal line and will be the AgeY is the vertical lien and will be Weight
What is the Algebraic equation of the best fit line in slope-intercept form? [Part B]
Slope-intercept form is y = mx + b
m is the gradient of the line, determined by calculating "change of y divided by change of x"
Age 2 and weight 32 would be the point (2, 32) on the graphAge 8 and weight 60 is the point (8, 60) in the graphTo compute for the gradient (m) we say:
(60 - 32)/(8-2)
= 28/6
m = 4.667
Next we calculate for b
The point on the graph where the line crosses the vertical line is known as the y-intercept, or b. (y-axis).
Put one of the graph's points, say (2, 32), and the amount of m you just computed into the slope-intercept form to calculate b.
That is:
32 = m(2) + b
Recall that m = 4.667
Hence 32 = 4.667 * 2 + b
32 = 6.667 + b
b = 32 - 6.667
b = 25.33
Using the equation for the line of best fit what is the approximate weight of the little girl at an age of 14 years old? [Part C]Given that we have the figures for m and b,
Recall that the function is: y = mx + b; and that
If x = 14 years, then
y = 4.667 * 14 + 25.33
y = 90.668
y ≈ 91 kg.

Determine whether each given pair of end points lies on the same horizontal or vertical line. If so, find the length of the line segment that joins the pair of points. If not, explain how you know the points are not on the same horizontal or vertical line.
Answer:
[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]
They lie on the same horizontal line
Distance = 11 units
[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]
They do not lie on the same vertical or horizontal line
Step-by-step explanation:
Given
[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]
[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]
Required
Determine if the points lie on the same vertical or horizontal line
A point is represented as: [tex](x,y)\\[/tex]
For a pair to lie on the same horizontal line, then they must have the same x values i.e. [tex](x,y_1)\ and\ (x,y_2)[/tex]For a pair to lie on the same vertical line, then they must have the same x values i.e. [tex](x_1,y)\ and\ (x_2,y)[/tex]Using the above illustration, we have:
[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]
The above have the same x values (0), hence they lie on the same horizontal line.
The distance between them is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
[tex]d = \sqrt{(0-0)^2 + (-2 - 9)^2}[/tex]
[tex]d = \sqrt{0^2 + (-11)^2}[/tex]
[tex]d = \sqrt{0 + 121}[/tex]
[tex]d = \sqrt{121}[/tex]
[tex]d = 11[/tex]
The distance between them is 11 units
[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]
The above pair do not have the same x value and they do not have the same y value.
Hence, they do not lie on the same vertical or horizontal line
