Divide:
Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.

The table shows the amount of money in your bank account over a period of 5 weeks. You plan to keep saving at the same rate until you have $800 in the account. Which equation could you use to find the number of weeks, n, it would take to reach your goal?.
The equation which is useful to find "n" number of weeks to reach our goal is 35n + 100 = 800.
How to form an equation?
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
As per the given table,
Amount of money in 0 weeks = $100
Amount of money in 1st week = $135
In 2nd week = $170, in 3rd week = $205
So there is a $35 increment each week.
Let's say it takes "n" number of weeks to reach the goal.
So, 35n + 100 = 800
Hence the answer is The equation which is useful to find "n" number of weeks to reach our goal is 35n + 100 = 800".

What are examples of linear equations?
An equation with only one variable is referred to as a linear equation in one variable. It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. A linear equation in one variable would be 9x + 78 = 18, for instance.Increased price= Selling Price - Original Price
Percent Increased = Increased price / Original Price × 100%
The increase of price: 334 – 268 = $66

On a certain hot summer's day, 586 people used the public swimming pool. The daily prices are for children$1.75 and $2.00 for adults. The receipts for admission totaled $1,078.75 How many children and how many adults swam at the public pool that day?
Answer: 373 children and 213 adults
Step-by-step explanation:
Children can be represented by x and adults can be represented by y.
x+y=586
1.75x+2y= $1078.75
x=586-y <-- substitute into 1.75x+2y=1078.75.
1.75(586-y) +2y=1078.75
1025.5 - 1.75y+2y =1078.75
0.25y = 53.25
y=213 adults
x + 213 = 586
x= 373 children
Check:
1.75(373) +2(213)=1078.75
1078.75=1078.75

Find the area of the shaded area
The area of the shaded circular region is 197.82 unit².
What is the area of a circle?The space a circle takes up on a two-dimensional plane is known as the area of the circle. The region contained within the circle's circumference or perimeter is another way to define the circle's area. A = πr², where r is the circle's radius, is the formula for calculating a circle's surface area.
The radius of the inner circle = 9 units
So, the area of the inner circle is given by
a = πr²
= 3.14 × 9²
= 3.14 × 81
= 254.34 unit²
The radius of the outer circle = 12 units
So, the outer circle area is given by
A = πR²
= 3.14 × 12²
= 3.14 × 144
= 452.16 unit²
So, the area of the circular shaded region is given by
Area = area of the outer circle - an area of the inner circle

Answer:
2.76×10^-3 m/s²
Step-by-step explanation:
You want to know the acceleration of the moon toward the Earth, given its distance is 3.8×10^8 meters, Earth's mass is 5.98×10^24 kg, and the gravitational constant is 6.673×10^-11 N·m²/kg².
AccelerationThe acceleration of one body by another is ...
a = GM/r²
where G is the gravitational constant, M is the body creating the gravitational field, and r is the distance between the masses.
Applicationa = (6.673×10^-11)(5.98×10^24)/(3.8×10^8)² N/kg
a = (6.673·5.98/3.8²)×10^(-11+24-16) m/s² ≈ 2.76×10^-3 m/s²

The range of a list or set is the difference between the smallest and largest numbers. To find the range, arrange all of the numbers in ascending order. Subtract (deduct) the lowest number from the highest. The answer provides the list's range.
What is the median?The median is discovered by sorting all data points and selecting the one in the middle (or if there are two middle numbers, taking the mean of those two numbers)
In two simple steps, you can calculate the mean or average of a data set: Add up all of the values to find the sum. Subtract the sum from the total number of values in the data set.
The mode, median, and mean are the three main measures of central tendency. Each of these measures describes a different indication of the distribution's typical or central value.

Step-by-step explanation:
The Sugar Sweet Company is going to transport its sugar to market. It will cost $6500 to rent trucks, and it will cost an additional $175 for each ton of sugar transported.
let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this equation to find the total cost to transport 16 tons of sugar.
The equation is C = 6500 + 175S
The total cost to transport 16 tons of sugar is $9300
From the question, we have
C = total cost
S represent the amount of sugar (in tons) transported.
C = 6500 + 175S
total cost to transport 16 tons of sugar = 6500 + 175(16)
= 6500 + 2800
= $9300
The total cost to transport 16 tons of sugar is $9300.

Diagonals of a rectangle divide it into two parts of equal areas.
Let ABCD be a rectangle.
In ΔABC and ΔADC,
AC=AC
By Alternate Interior Angles:
∠BAC=∠CAD
∠BCA=∠CDA
Hence, ΔABC≅ΔACD
∴ar(ΔABC) =ar(ΔACD)
Let ΔABC,
We draw a line AD perpendicular to BC, line EF parallel to BC passing through A and lines BE and CF , perpendicular to BC passing through B and C respectively.
In rectangle ADBE,

You took out a loan for $5000, with a 7.5% interest rate, over a period of 2 years. What is the accumulated interest?
Answers should be in $1,000.00 form (include $, comma, and period when necessary)
The accumulated interest on the loan given, equals to $778.125.
What is an accumulated interest?Also known as compound interest, means the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
Amount payable equals to:
= P(1+i/100)*n
= $5,000*(1 + 7.5%)^2
= $5,000 * 1.155625
= $5,778.125
The computation of the accumulated Interest goes as:
= Amount payable on loan - Loan Amount

Find the value of x, please show your work
Answer:
x = 80
Step-by-step explanation:
This shape is a pentagon, and all of the angles in a pentagon always add up to 540. So, using this, we can create an equation, 3x + 300 = 540. we can then use the reverse order of operations to solve this, first subtracting 300 from both sides. this gets us the equation 3x = 240. We then divide 3 from both sides to get x alone and get x = 80.
Answer:
x = 80°
Step-by-step explanation:
You want the value of x given a pentagon with two angles marked with expressions in x.
Sum of anglesThe sum of interior angles in an n-gon is 180° × (n -2). For the 5-sided figure shown, the sum of angles is 180° × 3 = 540°.
Using this value, we have ...
(x +40°) +125° +(x +5°) +(x +50°) +80° = 540°
3x +300° = 540° . . . . . . simplify
x +100° = 180° . . . . . . . divide by 3
x = 80° . . . . . . . . . . . . subtract 100°
The value of x is 80°.

(10 mi)/(5mi/h) = t
2 h = t
