Answer:
3000 books
Step-by-step explanation:
We know the author receives a one time fee of $2500. On top of that, the author will receive $1.50 per book sold. This is a constant rate and is linear because of this. We can use y=mx+b. M is the slope or rate of change. M here is $1.50. B is the starting value which is $2500 here.
We write y=1.5x+2500.
This equation will give the amount of money the author earns for x number of books sold. If y=7000 for the author earning 7000. We will use inverse operations to isolate and find x.
7000=1.5x+2500
7000-2500=1.5x+2500-2500
4500=1.5x
4500/1.5=x
3000=x
Answer:
The author must sell 300 books.
Step-by-step explanation:
The total amount earned = advance + books sold * money per book
We know they want to make 7000
The advance is 2500
They earn 1.50 for each book sold
b= number of books sold
Substituting in
7000= 2500 + 1.5b
Subtract 2500 from each side
7000-2500 = 2500-2500 + 1.5 b
4500 = 1.5 b
Divide each side by 1.5
4500/1.5 = 1.5b/1.5
3000 = b

Anumeha is mowing the lawns for a summer job. For every mowing job, she charges and initial fee of $10 plus a constant fee for each hour of work. Her fee for a 5-hour job, for instance is $35. Let F(t) denote Anumeha's for a single job F (measured in dollars) as a function of the number of hours t it took her to complete it. Write the functions formula
Answers
Answer:
F(t) = 10 +5t
Step-by-step explanation:
Income equals the initial fee plus the hours worked times the hourly rate
We know the initial fee = 10
hours = t
hourly rate =r
F(t) = 10 + r*t
We know a 5 hour job is 35 dollars
35 = 10 + r*5
Subtract 10 from each side
35-10 = 10-10 +5r
25 = 5r
Divide by 5
25/5 = 5r/5
5 =r
The hourly rate is 5
F(t) = 10 +5t

Answers
The given radius is = 60 feet
The volume of the sphere is given by = [tex]\frac{4}{3} \pi r^{3}[/tex]
So we will find the volume of the sphere using radius as 60 and pi as 3.14
Volume = [tex]\frac{4}{3}*3.14*60*60*60[/tex] = 902059.20 cubic feet
As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.
So volume of quarter sphere = [tex]\frac{902059.20}{4}[/tex]
= 225514.80 cubic feet

which of the following are roots of the polynomial function below? F(x)=x^3-3x^2+2
Answers
The roots of the polynomial function F(x)=x^3-3x^2+2 can be found by reducing the function to zero and solving for x, likely by applying synthetic division or the Rational Root Theorem, as the polynomial is of third order.
Explanation:In Mathematics, especially in algebra, we often encounter the concept of finding the roots of polynomial functions. The roots of the function F(x)=x^3-3x^2+2 can be found by setting the function equal to zero and solving for the variable x:
Step 1: Set the equation to zero: x^3-3x^2+2 = 0.Step 2: Try to factor the polynomial or use a solving method such as the quadratic formula if it was a second-order polynomial. But in this case, the polynomial is of third order, and in such cases you typically apply synthetic division or the Rational Root Theorem to find the roots.Note: This explanation suggests general approaches.

The only root of the polynomial function F(x) = x³ - 3x² + x + 5 is 2 + i.
Explanation:Let's go through the possible roots of this polynomial function one by one and see which of them will make the function equal to zero. Recall that if a number p is a root of a polynomial, then when we substitute p into the polynomial, the resulting value will be zero.
A. First, let's consider 2+i as a possible root.
We would evaluate F(2+i) = (2+i)³ - 3(2+i)² +(2+i) + 5 = 0.
Upon evaluation, it turns out that F(2+i) does indeed equal 0.
B. Now let's see if -2+i is a root.
We evaluate F(-2+i) = ((-2+i)³ - 3(-2+i)² + (-2+i) + 5. This happens not to equal 0. Therefore, -2+i is not a root.
C. Then, we check if 1 is a root by computing
F(1) = 1³ - 3×1² +1 +5. Upon computing, we find that this doesn't result in 0 either. So, 1 is not a root
D. Finally, let's check if 2 is a root.
We compute F(2)= 2³ - 3×2² +2 +5. This computation also doesn't result in 0, therefore 2 is not a root of the polynomial function.
In conclusion, the only given number that is a root of the function is 2 + i.

The average speed of an airplane is four times as fast as the average speed of a passenger train. To travel 1440 km, the train requires 12 h more than the airplane. Determine the average speeds of the train and the airplane.
Answers
Answer
Average speed of the train = 90 km/h and average speed of the airplane = 360 km/h.
Explanation:-
If speed of train = x then the speed of airplane = 4x km/h and we have the 2 equations
x = 1440 / (t + 12) (t = time taken by the train)
4x = 1440 / t................................(1) (t = time taken by train)
Multiply the first equation by 4:-
4x = 5760 / (t + 12).....................(2)
Combining equations (1) and (2):-
1440 / t = 5760 / (t + 12)
Cross multiplying:-
5760t = 1440t + 17,280
4320t = 17,280
t = 17280/4320
t = 4 hours
speed of train = 1440/ (4 + 12) = 90 km/h and speed of plane = 4*90 = 360 km/h.

Stu takes a job with a starting salary of $65,000 for the first year. He earns a 2% increase each year. How much does Stu make over five years?
$325,000
$331,500
$338,263
$358,826
Answers
Answer:
Stu makes $338,263 over five years.
Step-by-step explanation:
In order to find the total amount Stu would make after five years, you need to find out how much he will make each year based on the 2% increase. Starting with year 1 at $65,000, we need to take his total salary and multiply by 1.02 (or the whole salary plus an increase of 2%). So, in year 2, he would make $66,300. Again, we would take his year 2 total salary and multiply by 1.02 to get $67,626 for year 3. We apply these same steps to years four ($68,978.52) and five ($70,358.10). To find his income over the five years, we need to add his salary from all five years together to get a total of $338,263.
Answer:
Option C which is $ 338,263
Step-by-step explanation:
The salary for the first year = $65,000
Increase per year= 2 %
To find total money made in five years = ?
total earned in first year = $65,000
Total increase in money after first year = 2 % of 65,000
= [tex]\frac{2*65000}{100}[/tex]
=$ 1300
Total earned in second year = 65,000 + 1300
= $ 66,300
Total increase in money after second year = 2 % of 66,300
= [tex]\frac{2*66300}{100}[/tex]
=$ 1326
Total earned in third year = 66300 + 1326
= $ 67,626
Total increase in money after third year = 2 % of 67,626
= [tex]\frac{2*67626}{100}[/tex]
=$ 1352.52
Total earned in fourth year = 67626 + 1352.52
= $ 68978.52
Total increase in money after fourth year = 2 % of 68978.52
= [tex]\frac{2*68978.52}{100}[/tex]
=$ 1379.58
Total earned in fifth year = 68978.52 + 1379.58
= $ 70358.1
Total Made in all five years = 65000+66300+67626+68978.52+70358.1

What expression can be used to determine the total cost of buying g pounds of granola for $3.25 per pound and f pounds of flour for $0.74 per pound?
Answers
The expression for determining the total cost of buying granola and flour is (3.25/g) * g + (0.74/f) * f. The values of g and f represent the number of pounds of each item. To find the total cost, substitute the values into the expression.
Explanation:The expression that can be used to determine the total cost is:
Total cost = ($3.25/g) * g + ($0.74/f) * f
where 'g' represents the number of pounds of granola and 'f' represents the number of pounds of flour.
For example, if you wanted to find the total cost of buying 5 pounds of granola and 2 pounds of flour, you would substitute g = 5 and f = 2 into the expression to get:
Total cost = ($3.25/5) * 5 + ($0.74/2) * 2 = $16.25 + $1.48 = $17.73

Step-by-step explanation:
The experimental probability of rolling a 1 on the next roll is 0.1992 (B). The theoretical probability of rolling a 3 on a six-sided die is 0.1667 (A). The odds of an event with a probability of 2/7 are 2 to 5 (D).
Explanation:The experimental probability of rolling a 1 in this experiment is calculated by dividing the frequency of rolling a 1 by the total number of rolls. There were 245 occurrences of rolling a 1 out of 1230 total rolls. To find the experimental probability, you divide 245 by 1230, which gives you 0.1992.
Part B: The theoretical probability of rolling any particular number on a fair six-sided die is 1/6, because there are 6 possible outcomes and each outcome is equally likely if the die is fair. Therefore, the theoretical probability of rolling a 3 on the next roll is 0.1667 (which is equivalent to 1/6 when rounded to four decimal places).
When the probability of an event is 2/7, the odds of the event are 2 to 5 (not 2/5). This is because odds are expressed as the ratio of the number of successful outcomes to the number of unsuccessful outcomes. Since there are 2 chances of success and 5 chances of failure (7-2=5), the odds are 2 to 5.

You invest $4000 in an account at 6.5% per year simple interest. How much will you have in the account at the beginning of the 9th year.
Answers
Answer:
$6340
Step-by-step explanation:
First figure out what 6.5% of 4000 is by multiplying not dividing because dividing will give you a way bigger number.
4000 x 6.5%=260
260 x 9=2340
2340+4000=6340
Each group member is permitted to consume one-third of a pizza. If there are twenty-four members in the group, how many pizzas should be ordered?
Answers
Answer:
8
Step-by-step explanation:
so they are one third of a pizza so thats 1/3 and 24 memebers so basically you just have to multiply 1/3 x 24 = 24/3 which is 8.
Answer:
8 pizzas should be ordered.
Step-by-step explanation:
To get the number of pizzas to be ordered, all we simple need to do is to multiply the numbers of the group members by the amount to be consume by each group member. That is;
Number of pizzas to be ordered = amount to be consume by each group member × number of group members.
amount to be consume by each group member = [tex]\frac{1}{3}[/tex]
Number of group members = 24
We can now proceed to insert our values into the formula
Number of pizzas to be ordered = amount to be consume by each group member × number of group members.
Number of pizzas to be ordered = [tex]\frac{1}{3}[/tex] × 24
= [tex]\frac{24}{3}[/tex]
= 8
Number of pizzas to be ordered = 8
Therefore, 8 pizzas should be ordered.
