Answer:
x = 56, x = 30
Step-by-step explanation:
(a)
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540
72 + 2x + 99 + 89 + 3x = 540, that is
5x + 260 = 540 ( subtract 260 from both sides )
5x = 280 ( divide both sides by 5 )
x = 56
----------------------------------------------------------------
(b)
The sum of the exterior angles of a polygon = 360°
sum the exterior angles and equate to 360
94 + 56 + 4.5x + x + 1.5x = 360, that is
7x + 150 = 360 ( subtract 150 from both sides )
7x = 210 ( divide both sides by 7 )
x = 30

Jessica conducts an experiment. She flips a coin 100 times. In her experiment, she gets heads 40 times and tails 60 times. Based on her results, if she flipped the coin another 50 times, she should expect to flip heads _____ times.
Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.

The law of cosines is used to find the measure of Angle Q. Triangle Q R S is shown. The length of Q R is 20, the length of R S is 24, and the length of Q S is 34. To the nearest whole degree, what is the measure of Angle Q? 44º 49º 54º 59º
Answer:
44º
Step-by-step explanation:
We are given that a triangle QRS
QR=20 units
RS=24 units
QS=34 units
We have to find the measure of angle Q.
We know that cosine law
[tex]a^2=b^2+c^2-2bc cos A[/tex]
Using the formula
[tex](24)^2=(20)^2+(34)^2-2\times 20\times 34 cos Q[/tex]
[tex]576=1556-1360 cosQ[/tex]
[tex]1360osQ=1556-576[/tex]
[tex]1360 cos Q=980[/tex]
[tex]cos Q=\frac{980}{1360}[/tex]
[tex]cos Q=0.72[/tex]
[tex]Q=cos^{-1}(0.72)[/tex]
[tex]Q=44^{\circ}(approx)[/tex]
Answer:
Short and sweet... 44º

Your school's talent show will feature 8 solo acts and 2 ensemble acts. the show will last 82 minutes. The 4 solo performers judged best will give a repeat performance at a second 54 minute show, which will also feature the 2 ensemble acts. Each solo acts lasts x minutes, and each ensemble act last y minutes. write a system of equations
Answer:
System of equations: 8x + 2y = 82 and 4x + 2y = 54
Step-by-step explanation:
Given that:
8 solo acts and 2 ensemble acts will last for 82 minutes
4 solo acts and 2 ensemble acts will last for 54 minutes
Let,
x be the minutes solo acts lasts
y be the minutes ensemble acts lasts
According to given statement;
8x + 2y = 82
4x + 2y = 54
Hence,
System of equations: 8x + 2y = 82 and 4x + 2y = 54

Ron traveled 6.8 miles of his delivery route in 12 hours. At this same rate, which of the following is closest
to the time it will take for Ron to travel 20 miles?
O 3 hours
O 3.5 hours
O 6 hours
O 6.5 hours
Answer:
6.5 Hours
Step-by-step explanation:
If it takes Ron 12 hours to go 6.8 miles then 8 hours more is only 1.7 miles an hour. It will take him well over 6.5 hours to do 20 miles so 6.5 hours is the closest answer
The time that should be taken for Ron to travel 20 miles in 3.5 hours.
Given that
Ron traveled 6.8 miles in 1.2 hours.
We need to find out the time that should be taken for Ron to travel 20 miles.
So, the time taken should be
[tex]= \frac{20\ miles \times 1.2\ hours}{6.8\ miles}[/tex]
= 3.5 hours
Here we assume that time should be 1.2 hours instead of 12 hours.
Therefore we can conclude that The time that should be taken for Ron to travel 20 miles in 3.5 hours.

The perimeter of a rectangle is 27 inches. The ratio of length to width is 2:1. What are the length and width of the rectangle? Round answers to the nearest tenth.
Perimeter is the sum of the two lengths plus the sum of the two widths.
Divide the perimeter in half and that is the sum of one length and one width.
27/2 = 13.5
The ratio is 2:1, add the ratio: 2 +1 = 3
Divide the sum by 3:
13.5/3 = 1.5
Multiply that the each portion of the ratio:
4.5 x 2 = 9
4.5 x 1 = 4.5
The length is 9 inches
The width is 4.5 inches

An equation is shown below. 3(2x+1)+5=2(3x+5) Which of the following statements describes the solutions to this equation?
Answer:
Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.
Step-by-step explanation:
Given System of equations is 5x + 2y = 3 (equation 1) and 2x - 3y = 1 (equation 2)
Second System of equations is 2x - 3y = 1 and 7x - y = 4
How we got 7x - y = 4
Step 1: Multiply 2x - 3y = 1 by 1, we get the same 2x - 3y = 1
Step 2: Add 5x + 2y = 3 with 2x - 3y = 1
5x + 2x + 2y - 3y = 1
7x - 3y = 1
We have got second equation 7x - 3y = 1
Thus, Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.

At the Henry Doorly Zoo the giraffe grew from 24 inches to 60 inches long in five months. Find
the percent of change and show your work clearly. Is this a percent increase or percent
decrease?
Answer:
150%
It is a percentage increase
Step-by-step explanation:
We start by calculating the percentage increase
Mathematically, we have this as;
Percentage increase = (new value - old value)/old value * 100%
New value = new height = 60 inches
old value = old height = 24 inches
Substituting these values, we have ;
(60-24)/24 * 100%
= 36/24 * 100%
= 1.5 * 100% = 150%
It is a percentage increase as we can see growth
