Natalie has 412 apples that she must package into bags. Each bag must hold 8 apples. Natalie divides 412 by 8 and gets an answer of 51 R 4. What is the correct interpretation of R 4 for this situation? 1. Natalie can fill 4 more bags after filling 51 bags. 2. Natalie has 4 bags left after filling 51 bags. 3. Natalie has 4 apples left after filling 51 bags. 4. Natalie can fill at most 51 bags with 4 apples each.
Answer:
3.
Step-by-step explanation:
The answer is 51 R4, meaning that 54 bags HAVE been filled and 4 apples are the remainder. Therefore, there are 4 apples that have not been bagged and Natalie would need another bag to bag all the apples.

A candy bar is created with 28 cubic centimeters of chocolate. If the length is 8 cm and the width is 6 cm, what is the height of the candy bar? Round to the nearest hundredth.
Answer:
0.58cm
Step-by-step explanation:
l×b×h=volume
Given:
Voume=28cm^3
l=8cm
width or breadth=6cm
h=?
applying the above formula
l×b×h=28cm^3
6×8×h=28cm^3
h=28/48=0.58cm
Coach reynolds bought 23 bottles of sports drink. Each bottle contains 25 ounces of sports drink. If he wants to have 700 ounces of sports drink for the football `game on friday night, how many more bottles of sports drinks should Coach reynolds buy.
4th grade.
Answer:
5 more bottles
Step-by-step explanation:
23 x 25 will give us how many ounces Coach Reynolds have already.
23 x 25 is 575
700 - 575 will give us how many ounces he needs to buy.
700 - 575 is 125
125 divided by 25 will give us how many bottles he needs to buy
125 divided by 25 is 5
So 5 more bottles

A car dealer purchases a car for $5,000 and sells for $6,600 what is his percentage profit? Round your answer to the nearest whole percent
Answer:
32%
Step-by-step explanation:
The percentage profit is the ratio of profit to original cost, expressed as a percentage. The profit is the difference between the selling price and the cost.
profit = selling price - cost
profit = $6600 -5000 = $1600
The ratio of that to cost is ...
$1600/$5000 = 0.32
As a percentage, that is ...
0.32 × 100% = 32%
The car dealer's profit was 32% of his cost.
What is the total price of an $18.97 item plus 8% slaes tax?
Answer:
$20.49
Step-by-step explanation:
8% = 8/100 = 0.08
Therefore, 8% of 18.97 = 0.08 x 18.97 = 1.5176
So the total price = 18.97 + 1.5176 = 20.4878 = $20.49
Alternatively,
108% = 108/100 = 1.08
18.97 x 1.08 = 20.4878

What is 4x – 5 = 16 ? I have to show my work
Answer: x = 21/4
First, you want to Add 5 to both sides of the equation:
4x - 5 + 5 = 16 + 5.
Then you want to simplify:
4x = 21.
Divide both sides of the equation by the same term:
4x/4 = 21/4.
Then you want to simplify:
x = 21/4.
The final solution is:
x = 21/4
Exact Form:
x = 21/4
Decimal Form:
x = 5.25
Mixed Number Form:
x = 5 1/4

An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the number of cake pop and y represent the number of cookie. Hence:
x + y ≥ 10 (1)
Also:
4x + 2y ≤ 30 (2)

5 A line passes through the point (-4,-1) and has a slope of 4 Write an equation in point-slope form for this line.
Answer:
y + 1 = 4(x + 4)
Step-by-step explanation:
When you write an equation in point-slope form, you only need two things: a point and a slope.
Given:
point: (-4, -1)slope (m): 4The standard point-slope equation is
y - y₁ = m(x - x₁)Plug in what you know.
y - (-1) = 4(x - (-4))Simplify.
y + 1 = 4(x + 4)This is your equation.

Your parents invest $10,000 in a college fund when you are born. They find a fund that will return 8% per year for 18 years.
When you are 18 you find a school that charges $12,000 tuition per year. Tuition increases at a rate of 11% per year (so the second year will have a tuition of $13,320) , will this money take care of four years of school? How many years of college will this take care of? Explain your answer fully.
The interest is compounded in the investment and the fees, the 4 years
school fees is however larger than the future value of the investment.
Response:
The money is less required to take care of four years of schoolTwo yearsHow can the future value of the amount invested be found?First part:
The future value, FV, of the investment after 18 years is given as follows;
[tex]FV = \mathbf{PV \cdot (1 + i)^n}[/tex]Where;
PV = The present value = $10,000
i = The interest rate = 8% = 0.08
n = The number of years = 18
Which gives;
[tex]FV = 10,000 \times (1 + 0.08)^{18} \approx \mathbf{39,960.195}[/tex]
The future value of the investment, FV = $39,960.195
The school fees each year is given as follows;
Fees = First year fees·(1 + r)ⁿ
Where;
First year fees = $12,000
r = Increase rate of the school fees = 11% = 0.11
n = The number of years
The school fees for four years is given as follows;
∑Fees = $12,000 + $12,000·(1 + 0.11) + $12,000·(1.011)² + $12,000·(1.011)³
Which gives;
∑Fees = 12,000 + 12,000·(1 + 0.11) + 12,000·(1 + 0.11)² +12,000·(1 + 0.11)³ = 56,516.772
The total tuition fees for four years = $56,516.772
The future value of the investment after 18 years, $39,960.195 is less
than the amount required as school fees for four years, therefore;
The money is less than the amount to take care of four years of schoolSecond part:
The fees for 3 years of school is given as follows;
[tex]\displaystyle \sum \limits_{n = 1 }^3[/tex] = 12,000 + 12,000·(1 + 0.11) + 12,000·(1 + 0.11)² = 40,105.2 > 39,960.195
The fees for 2 years of school is given as follows;
[tex]\displaystyle \sum \limits_{n = 1 }^2[/tex] = 12,000 + 12,000·(1 + 0.11) = 25,320 < 39,960.195
The number of years of college the value of the investment will take care of is therefore;
