Graph the inequality on a number line. (Section 4.1) 10. x > 5
Answer:
Please see the attached image.
Step-by-step explanation:
If x > 5, it means that the value of x can take on any value that is greater than 5. Therefore, if you draw a number line, you can put a circle on the number 5 and draw an arrow pointing to the right (in the positive direction, representing all the numbers greater than 5). It is important to note that the circle you draw on the number 5 should not be shaded. This is because, according to the problem, while x can be greater than 5, it cannot equal 5. A hollow circle signifies that the value cannot equal the number circled exactly. I hope this answers your question.
write the letter of the correct choice in the blank
I got stuck, I need your help and please answer all 4 ques.
thank u
Can someone help on Question C?
It's - b + a
Because we're going down the arrow on b or the opposite direction of b. Then, up to C where its vector is a as it lies half way on AC with half of the line labelled a. So, the other half must be also a.
Hope this helps!
Find the value of a,b and c from the following figures .
Answer:
a=c=30⁰, b=150⁰.
Step-by-step explanation:
angle R is 120⁰ (vertically opposite angle)
so, for vertically opposite angle c we have,
30⁰+120⁰+c=180⁰
Hence, c=30⁰.
angle a = angle c = 30⁰ (corresponding angle).
180⁰-c = b (from figure being straight line)
or, b=180⁰-30⁰
hence, b=150⁰

There are 26 students in William's math class. The mean height of the students is 160 cm, and the median height is 156 cm. The interquartile range of the heights is 18 cm, and the mean absolute deviation of the heights is 4.6 cm.
Part A: Suppose the students in William's math class are listed in order from shortest to tallest. What is the difference between the height of the seventh student in the list and the height of the twentieth student in the list?
Part B: Suppose a new student joins William's math class, and his height is 160 cm. What is the mean height of students in the class with the additional student?
Please answer both parts for 50 points. :))
Answer:
To answer this question you will use the median height of 156 centimeters and the fact that there are 26 kids in the class to know that the median is not in the data set, therefore it breaks the data into two equal halves with 13 in each half.There would be 13 less or equal to the median height.

8.33 Suppose Paul receives a 6% raise every year. After four such raises, what is the total percentage increase to the nearest whole percent?
Answer:
Given:
Suppose Paul receives a 6% raise every year.
To find:
After four such raises, the total percentage increase to the nearest whole percent.
The formula used to calculate percentage is: (value/total value)*100%.
Step-by-step explanation:
Step 1 of 1
Assume his salary is originally 100 dollars.
Then, in the next year, he would have 106 dollars, and in the next, he would have 112.36 dollars.
The next year he would have 119.1016 dollars and in the final year, he would have 126.247.
As the total increase is,
((126.247 -100)/100) *100
= 26.247%
the answer is 26%.
19. A fabric dye was sold at $5.75 per 100 ml. Steven bought 4 L of this dye. How much did he pay?
Answer:
Step-by-step explanation:
(4l = 4000ml)
100ml = $5.75
4000ml = x
cross multiply
100x = (5.75 ×4000)
100x/100 = 23000/100
x = $230
8.3.9 On December 1, Tom's House of Dollhouses increased the prices on all of its dolls by 25%. In January, Tom is having a sale where all dolls are priced 20% off the December prices. For any doll, is the January price higher than, lower than, or the same as the November price for that same doll? Does your answer depend on the doll's original price?
Answer:
The January price of the doll is same as the November price. It does not depend on the original price.
Step-by-step explanation:
- We are given with a word problem
- We are asked to find whether the January price is higher or lower or equal to the November price.
- We can do this in two steps
Step 1 : Finding the price of doll in December and January
Step 2 : Comparing them.
Step 1 of 2
Let x be the price of any doll in Tom's House.
The percentage increase in December is 25%
That is [tex]$\frac{1}{4} \times x=\frac{x}{4}$[/tex]
Then the price in December is
[tex]x+\frac{x}{4}=\frac{4 x+x}{4}$$\\ \frac{4 x+x}{4}=\frac{5 x}{4}[/tex]
And the percentage decrease in January is 20%
That is [tex]$\frac{20}{100}=\frac{1}{5}$[/tex] of that price in December
[tex]$$\begin{aligned}\frac{1}{5} \times \frac{5 x}{4} &=\frac{5 x}{5 \times 4} \\\frac{5 x}{20} &=\frac{x}{4}\end{aligned}$$[/tex]
8.36 Polly the Penguin invested $250 in the Antarctic stock market. During the first year her investment suffered a 15% loss, but during the second year the remaining investment showed a 20% gain. Over the two-year period, what was the percent loss or gain in Polly's investment?
Answer:
The percentage gain in Polly's investment over the two year period will be 2%.
Step-by-step explanation:
Given:
- Polly the Penguin invested $250 in the Antarctic stock market.
- During the first year her investment suffered a 15% loss, but during the second year the remaining investment showed a 20% gain. Over the two-year period.
To Find:
- The percent loss or gain in Polly's investment.
The formula used to calculate percentage is: (value/totalvalue) x100%
- First, we determine the loss suffered by multiplying the loss percentage with the investment amount. Then, we get the amount after the loss is calculated. Then, we calculate the gain by multiplying the gain percentage with the previous amount to get the net amount in the second year.
Step 1 of 2
- The 15% loss in the first year on the investment amount $250 can be calculated as
[tex]$$\begin{aligned}&=250-15 \% \text { of } 250 \\&=250-\frac{15}{100} \times 250 \\&=250-\frac{3}{20} \times 250 \\&=250-\frac{750}{20} \\&=250-37.5 \\&=\$ 212.50\end{aligned}$$[/tex]
Step 2 of 2
- The 20% gain in the second year can be calculated as
[tex]$$\begin{aligned}&=212.50+20 \% \text { of } 212.50 \\&=212.50+\frac{20}{100} \times 212.50 \\&=212.50+42.50 \\&=\$ 255\end{aligned}$$[/tex]
- Here, we can observe that the total profits increased by $5 from the initial investment of $250. This means that 1% gain is equal to $2.50. So, 2% gains mean $5.
Answer:
5% gain

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
Write and solve an equation to determine the measure of angle y.
Answer:
90°
Step-by-step explanation:
In the picture, if you make a shape of the angles (including x°, y°, and the undefined angle), it is a circle, therefore it is 360° because a circle is 360°.
First, you add 50° + 40°, which gives you 90°. The undefined angle, which is 50° + 40° vertical angle is also 90° Therefore x° and y° must equal 90°.

8.3.5 Ana's monthly salary was $2000 in May. In June, she received a 20% raise. In July, she received a 20% pay cut. After the two changes in June and July, what was Ana's monthly salary?
Answer:
After July, Ana's monthly salary was $1920
Step-by-step explanation:
In May, Ana's monthly salary was $2000. During the next month, the salary increased by 20%, or (0.2)(2000)
[tex]2000+(0.2)(2000)=2000+400=2400[/tex]
So, in June, Ana's monthly salary was $2400. During the next month, the salary decreased by 20%, or (0.2)(2000)
[tex]2400-(0.2)(2400)=2400-480=1920[/tex]
Therefore, after the two changes, Ana's monthly salary was $1920
Answer:
Now Ana's monthly salary is 1920$.
Step-by-step explanation:
Given: Ana's salary in may =2000$
in June she received 20% raise
in July she received 20% pay cut.
To find Ana's monthly salary after the two changes in June and July.
we have to first find Ana's salary at the end of June month with 20% raise. and then her salary after the end of July month with the pay cut of 20%.
Step 1 of 2
Ana's salary after June month when she got 20% raise in his salary after May is equal to
[tex]=2000+(20 \% \cdot 2000)$\\ $=2000+\left(\frac{20}{100} \cdot 2000\right)$\\ $=2400 \$$[/tex]
her new salary after May will be 2400$.
Step 2 of 2
now she got a pay cut of 20% on his new salary from July month
so, her salary after that would be equal to
[tex]=2400-(20 \% \cdot 2400)$\\ $=2400-\left(\frac{20}{100} \cdot 2400\right)$\\ $=2400-480$\\ $=1920 \$$[/tex]
