find area and perimeter
Answer: The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

In the figure below, m∠A = 72° and m∠B = (5x + 8)°.
If ∠A and ∠B are supplementary angles, which equation represents their relationship, and what is the value of x?
A.
72 + (5x + 8) = 90
x = 34
B.
72 + (5x + 8) = 180
x = 52
C.
72 + (5x + 8) = 90
x = 2
D.
72 + (5x + 8) = 180
x = 20
Answer:
D. 72 + (5x + 8) = 180, x = 20.
Step-by-step explanation:
Supplementary angles are angles that add up to 180, so the equation would be 72 + (5x + 8) = 180.
Now here, to find the value of x, solve for x.
72 + (5x + 8) = 180
5x + 8 = 108
5x = 100
x = 20
Your answer is D, 72 + (5x + 8) = 180, x = 20.

From the bar chart, we can see that the the interval 130-150 has two bars in it:
Interval 130-140 with the highest frequency of 5
Interval 140-150 with frequency of 2
Therefore to find the percentage between 130-150 we add up the frequencies 2+5=7 and divide by the total frequency of 15 people all multiplied by 100
=7/15×100= 46.67%
Percentage of participants with heart rate between 130 and 150 =46.67%

What is the equation of the following line written in slope-intercept form?
y = -5x
y = 5x
y = 5/x
Answer:
y=5x
Step-by-step explanation:
first, we know that a rising line's slope is always positive, so the first one is incorrect
let's figure out the slope: y-y'/x-x' is the formula.
now, -5-5/-1-1= -10/-2= 5. so the slope of this line is 5.
Find the value of x in the isosceles triangle below then find the measure of the base angle.
x = __°
Measure of 1 base angle = __°
Answer: [tex]x=13[/tex], one base angle measures [tex]74^{\circ}[/tex]
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so:
5x + 9 = 8x - 30 [congruent angles have equal measure]9 = 3x - 30 [subtract 5x from both sides]39 = 3x [add 30 to both sides]x = 13 [divide both sides by 3]Hence, the measure of one base angle is [tex]5(13)+9=\boxed{74^{\circ}}[/tex]

Mr Lim, who is in Singapore, wants to make a phone call to his client in
Chicago. The local time in Chicago is 14 h behind the local time in Singapore.
If Mr Lim wants to call his client at 7 a.m. (Chicago local time), at what time
(Singapore local time) must he make the call?
Answer:
5pm
........................
Mr. Lim has to make calls at 5:00 pm if he wants to talk with his client at 7:00 AM in Chicago due to the different time zone.
What are Time Zones?A time zone is any place that observes the same standard time. For current time zones around the world, see the interactive Time Zone Map.
Given, Mr. Lim, who is in Singapore, wants to make a phone call to his client in Chicago. The local time in Chicago is 14 h behind the local time in Singapore. If Mr. Lim wants to call his client at 7 a.m. (Chicago local time)
Since there is a time difference between the two countries. Mr. Lim has to make calls 14 hours before as per the local time zone
14 hours before 7 AM is 5: 00 PM.
Therefore, Due to the time difference, Mr. Lim must make calls at 5:00 p.m. if he wishes to speak with his client at 7:00 a.m. in Chicago.

Find the distance between the pair of points (-1, 4) and (-3, 7)
no links
Answer: d=sqrt(13)=3.605
Step-by-step explanation:
We know that the distance between the two points (x 1 ,y 1 ) and (x2,y 2 ) is
d= sqrt((x2-x1)^2 +(y2-y1)^2 )
as given
x1=-1 ,y=4 ,x2=-3,y2=7
d=sqrt((-3+1)^2+ (7-4)^2)
d=sqrt((-2)^2+(3)^2)
d=sqrt(4+9)
d=sqrt(13)=3.605
If a sample proportion is 0.55, which of the following could be a 90% confidence interval for the population proportion? Select all that apply.
(a) Lower bound: 0.50; Upper bound: 0.60 (b) Lower bound: 0.53; Upper bound: 0.59 (c) Lower bound: 0.52; Upper bound: 0.58 (d) Lower bound: 0.60; Upper bound: 0.70 (e) Lower bound: 0.45; Upper bound: 0.60
Answer:
The correct options are a and c.
Step-by-step explanation:
Confidence interval:
A confidence interval is given by the sample proportion plus/minus the margin of error. This means that the confidence interval is symmetric, that is, the difference between the upper bound and the sample proportion has to be the same as the difference between the sample proportion and the lower bound.
Sample proportion is 0.55
So options for the confidence interval are:
Lower bound - upper bound
0.54 - 0.56
0.53 - 0.57(which means that option b is wrong)
0.52 - 0.58(which means that option c is right)
...
0.5 - 0.6(which means that option a is right).
The correct options are a and c.
The confidence interval is the range of value between which the true population proportion would lie given a certain margin of error. Hence the correct options are A and C
Hence, the upper and lower boundary would the same error value above and below the mean proportion.
Evaluating the options given :
Error below = 0.50 - 0.55 = -0.05
Error above = 0.60 - 0.55 = 0.05
Error below = 0.53 - 0.55 = -0.02
Error above = 0.59 - 0.55 = 0.04
Error below = 0.52 - 0.55 = -0.03
Error above = 0.58 - 0.55 = 0.03
Error below = 0.60 - 0.55 = 0.05
Error above = 0.70 - 0.55 = 0.15
Error below = 0.45 - 0.55 = -0.10
Error above = 0.60 - 0.55 = 0.05
Therefore, the only options with equal margin of error, above and below the mean are options A and C.

Which graph represents the solution set of the system y ≤ x2 – 1 and x > y2 – 6?
The fourth option is indeed correct on Edge 2021.
The graph that represents the system of nonlinear inequalities is graph (a)
The nonlinear inequalities are given as:
[tex]y \le x^2 - 1[/tex]
[tex]x > y^2 - 6[/tex]
Rewrite the above nonlinear inequalities as:
[tex]y - x^2 \le - 1[/tex]
[tex]x -y^2 > -6[/tex]
[tex]y - x^2 \le - 1[/tex] means that the inequality has a solid line, and the outside part is shaded
[tex]x -y^2 > -6[/tex] means that the inequality has a dotted line, and the inner part is shaded
So, the graph that represents the system of nonlinear inequalities is graph (a)
