A and B provide very little information therefore I would chose C or D. If you look at D it has “Tea Spoons” were that would be right if the question was different. You see your question says “All the Units” UNITS so D cant be correct. This means the answer ost probably should be C.
Question 2:
Same as the last one this has units so I would go for C because it is te most accurate way of time periods.
Question 3:
This could get you off guard because it says “could NOT be used to convert” in short that is referring to the false answer and it seems like the answer here would be D.
Question 4:
Now this question asks that which relation is going to be first. So if you want to make it easier which they are asking you to do I would go for C.

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?
Answers
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]

Find the area of the shaded region.
Answers
Answer:
[tex]18 ft^2[/tex]
Step-by-step explanation:
You could calculate the area of the trapezoid and then subtract the area of the triangle.
Area of a trapezoid:
[tex]A = \frac{a+b}{2}h[/tex]
Plug values in:
[tex]A = \frac{6+12}{2}(6)[/tex]
Add 6 and 12:
[tex]A = \frac{18}{2}(6)[/tex]
Simplify:
[tex]A = 54[/tex]
Area of a triangle:
[tex]A = \frac{1}{2}bh[/tex]
Plug values in:
[tex]A = \frac{1}{2}(6)(12)[/tex]
Simplify:
A = 36
Subtract the area of the triangle from the area of the trapezoid
54 - 36 = 18
You could also calculate the area of the shaded region by assuming that they're congruent meaning the base would be half of 6 which is 3 and the height would be 6 so the area of one would be 1/2 (6)(3) but since they're is 2 you wouldn't need the 1/2 since multiplying by 2 would cancel it out so the area would be (6)(3) = 18

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.
Answers
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°.

19. A fabric dye was sold at $5.75 per 100 ml. Steven bought 4 L of this dye. How much did he pay?
Answers
Answer:
Step-by-step explanation:
(4l = 4000ml)
100ml = $5.75
4000ml = x
cross multiply
100x = (5.75 ×4000)
100x/100 = 23000/100
x = $230
covert the 4 L into mL: 4,000 mL
divide 4,000 mL by 100 mL: 40 mL
multiply 40 mL by $5.75: $230.00

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?
Answers
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

Graph the inequality on a number line. (Section 4.1) 10. x > 5
Answers
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.
