Answer:
she will need 8.4 so just get 9
If each box has 500 sheets, Megan should purchase 9 packs if she needs 4200 sheets of paper.
What are arithmetic operations?The area of arithmetic operations encompasses the study of numbers and their operations, which are essential to all other branches of mathematics. These systems use the four operations of addition, subtraction, multiplication, and division as their foundation.
It is given that, Megan purchases 4200 sheets of paper because each box has 500 sheets.
Suppose x be the number of packs,
Applying division to select how to share pack equitably among a group, divide the object into equal halves or groups.
The number of packs needed will be,
x=4200/500
x=8.4 ≈ 9
Thus, she should buy 9 packs if each pack has 500 sheets.

Rhianna is baking a cake and some cookies for a party. She used cups of flour for the cake. For each tray of cookies, she needs cups of flour. She decides to use at least 15 cups of flour for the cake and the cookies.
Assuming she can make fractional trays of cookies, how many trays, x, can she make? Select the inequality that includes the minimum number of trays of cookies Rhianna can make.
Answer:
x > 15
Step-by-step explanation:
At least means that x will be greater than 15 so it is x > 15.

Marty has saved $63. He spent $3 on a video rental. Write a ratio as a fraction in simplest form to represent what portion of his savings he has left.
Answer:
60/63, 60 : 63
Step-by-step explanation:
63 - 3 = 60
60 is left over. The total amount is 63
Therefore 60/63
Gilligan sees a ship coming close to the shore he's standing on. He wants to determine the distance (segment SD) from the ship to the shore. He walks 130 ft along the shore from point D to point C and marks that spot. Then he walks 23 ft further and marks point B. He turns 90°and walks until his location (point A), point C, and point S are collinear.
Answer the following questions making sure to show all your work.
(a) Can Gilligan conclude that triangle ABC and triangle SDC are similar? Why or why not?
(b) Suppose AB = 50 ft. What is the distance from the ship to the shore? Show all your work and round your final answer to the nearest tenth of a foot.
The two triangles are both right triangles and are both formed by the
intersection of the lines AS and BD and are therefore similar.
Response:
(a) Yes, ΔABC is similar to ΔSDC according AA similarity postulate
(b) The distance from the ship to the shore is approximately 282.6 feet
How can similarity between the triangles used to find the distance SD?(a) Yes, Gilligan can conclude that ΔABC and ΔSDC are similar by
Angle-Angle, AA, similarity postulate.
Reason:
Angle ∠SCD in ΔSDC and ∠ACB in ΔABC are vertically opposite angles,
and they are therefore congruent by vertical angles theorem.
∠SDC = 90° and ∠ABC = 90° therefore ∠SDC ≅ ∠ABC because all 90°
are congruent.
Therefore, two angles in ΔABC are congruent to two angles in ΔSDC,
therefore, ΔABC is similar to ΔSDC according to AA similarity postulate
(b) The ratio of corresponding sides in similar triangles are equal,
therefore;
[tex]\dfrac{BC}{DC} = \mathbf{\dfrac{AB}{SD}}[/tex]
Which gives;
[tex]\dfrac{23}{130} = \dfrac{50}{SD}[/tex]
[tex]SD = \dfrac{130}{23} \times 50 \approx 282.6[/tex]
The distance from the ship to the shore, SD ≈ 282.6 ft.Learn more about triangle similarity postulates here:

Which table represents a linear function?
Answer:
Find the slope for each of the points in the table. If all the slopes equal each other, the table represents a linear function. If not, then it's the opposite.
Step-by-step explanation:
(You didn't post the full picture, but I'll try to make sense of your problem and answer anyways.)
A linear function, or a line, has a constant slope. This means that no matter where you are on the line, it was always be "rising" some y and "running" some x. It will never be fluctuating in slope or anything like that because it's a line, not a curve, not a zigzag, etc. Just a line.
How do we observe this in tables? Well, remember that the slope m can be found with the following formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
where (x1, y1) and (x2, y2) are two points on a line.
So, we can show that all these points have equal slopes to see if they form a line. For example, let's look at the table shown in the picture. We have five points, so let's find the slope for two of them at a time.
First, let's find the slope between (1, 5) and (2, 20).
[tex]m=\frac{20-5}{2-1} \\m=\frac{15}{1} \\m=15[/tex]
The slope between these two points is 15.
Now, let's find the slope between (2, 20) and (3, 45).
[tex]m=\frac{45-20}{3-2} \\m=\frac{25}{1} \\m=25[/tex]
And the slope is ... 25? This can't be right!
Well, it is. This means that these three points can't all form a line, and therefore, all of these points can't form a line. So, the table shown in the picture does not represent a linear function. Do this for the other tables in the question, and you got yourself your answer.

What is the value of b?
A)6
B)27T3
C)зVT3
D) 3V14
Applying the leg rule, the value of b in the triangles is: C. 3√13.
What is the Leg rule?The leg rule states that where the altitude of a right triangle bisects its hypotenuse, then, hypotenuse/leg = leg/part, of the right triangle.
Given:
Hypotenuse = 4 + 9 = 13
Leg = b
part = 9
Thus:
13/b = b/9
Cross multiply
b² = 9 × 13
b = √(9 × 13)
b = 3√13
Thus, applying the leg rule, the value of b in the triangles is: C. 3√13.

One week, Steph worked 20 hours, Marco
worked 12 hours, and Destiny worked 32 hours.
How much did the owner, Layla, pay herself?
Answer: 9
Step-by-step explanation:
Add 20, 12, and 32 together then divide by 7 because it says "One week" and a week is 7 days. So, it should be like 20 +12 + 32= 64
64 / (divided by) 7 = 9
The number of daily work hours, if in One week, Steph worked 20 hours, Marco worked 12 hours, and Destiny worked 32 hours, is 9.1 hours.
What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
One week, Steph worked 20 hours, Marco worked 12 hours, and Destiny worked 32 hours,
Calculate the total time of work as shown below,
The total time = 20 + 12 + 32
The total time = 64 hours in a week
Calculate the daily work time as shown below,
Daily work time = 64 / 7

Calculus
To answer the questions made, the following calculations must be made:
1. If 15 apricots cost R5.60, how many apricots will cost R10.08?
5.60 = 1510.08 = X10.08 x 15 / 5.60 = X151.2 / 5.6 = X27 = XTherefore, 27 apricots will cost R10.08.2. How much will it cost for 1kg of polony if 0.35 kg of polony costs R25.10?
0.35 = 25.101 = X25.10 / 0.35 = X71.71 = XTherefore, 1 kg of polony will cost R71.71.3. If 12.5 kg of sugar cost R90, how much will 7.2 kg of the sugar cost?
12.5 = 907.2 = X7.2 x 90 / 12.5 = X648 / 12.5 = X51.84 = XTherefore, 7.2 kg of sugar cost R51.84.4. A scooter uses 6.5ℓ petrol to travel a distance of 130 km. How much petrol will it use to travel a distance of 80km?
130 = 6.580 = X80 x 6.5 / 130 = X520 / 130 = X4 = XTherefore, it will use 4 liters of oil to travel a distance of 80km.5. Peter used 5ℓ of paint to paint a wall that is 8m long and 5m high. How many square meters can Peter paint with 1ℓ of paint?
