The choir is selling candy bars to raise money for a trip they sell each candy bar for $5 there are 7 candy bars in each box and each student in the choir can sell 2 boxes of candy bars per day there are 5 students in the choir how much money can the choir raise in 8 days?
Answer:$2800
Step-by-step explanation: Lets first figure out how much money a box of candy bars is worth. We know that each candy bar is worth $5 and that there are 7 candy bars per box. We can multiply 7*5 to figure out that each box is worth $35.
Now lets figure out how many boxes can be sold each day. Each student can sell two boxes a day. 5 students selling 2 boxes each is 5*2= 10 boxes total sold a day.
Now finally we use what we found to figure out the amount of money made per day. We know that there are 10 boxes being sold and that each box makes them $35. We just multiply 10 boxes by $35 to get $350 dollars each day.
Since they sell for 8 days we just multiply 8*$350 to get $2800.

If n is any positive 2-digit integer, what is the greatest positive integer that must be a factor of n(n+1)(n+2)(n+3)?
Step-by-step explanation:
Notice that in n(n + 1)(n + 2)(n + 3):
Exactly 2 of them are multiples of 2,
At least 1 of them is a multiple of 3, and
At least 1 of them is a multiple of 4.
Since one of the multiples of 2 is already counted in the multiple of 4 we can ignore it.
Hence we have 2 * 3 * 4 = 24.
The greater positive integer that must be a factor is 24.

Mark invests $6,700 in an online savings account which gives 4.2% simple annual interest. He also invests $6,000 in a savings account at his local bank which gives 6.9% simple annual interest. After fifteen years how much more interest will it have earned, to the nearest dollar?
Answer:
$4,221.00 for online and 6,210.00 for the instore
Step-by-step explanation:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4.2%/100 = 0.042 per year.
Solving our equation:
A = 6700(1 + (0.042 × 15)) = 10921
A = $10,921.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,700.00 at a rate of 4.2% per year for 15 years is $10,921.00.
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6.9%/100 = 0.069 per year.
Solving our equation:
A = 6000(1 + (0.069 × 15)) = 12210
A = $12,210.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 6.9% per year for 15 years is $12,210.00.
Before a football game can be played, the playing field must be painted. Football fields are rectangles. How can a couch guarantee that the field he is about to paint is a rectangle and not a parallelogram using only a tape measure?
Answer and Step-by-step explanation:
The only way the coach can guarantee that he is about to paint a rectangle using only a tape measure is by measuring opposite sides of the field and be assured that they are equal.
This is because the opposite sides of a rectangle are always the same, else it is not a rectangle.

Elena has $225 in her bank account. She takes out $20 each week for weeks. After weeks she has d dollars left in her bank account. Write an equation that represents the amount of money left, d, in her bank account after 5 weeks.
a)20(5)+225=
b)225(5)−20=
c)22520+5=
d)225−20(5)=
.How much money, d, will Elena have in her account after 7 weeks?
Answer:
the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.

A sales associate farms a neighborhood with 750 homes. The owners seem to list their homes every six years. How many listings should the sales associate obtain if she can list 40% of the homes in the neighborhood
Answer:
50 homes
Step-by-step explanation:
Given that:
Total Number of homes = 750
Years at which home is listed = 6
Thus average listing per year = (total number of homes / years)
Average listing per year = 750 / 6
Average listing per year = 125 homes
If 40% of homes in the neighborhood can be listed :
0.4 * 125
= 50 homes
Sales associate should obtain listing of 50 homes
Calculation of homes listing obtained by Sales associate
Given : Total 750 houses with listing tendencies every six years.
So, average annual houses listing = 750 / 6 = 125
Also, listings = 40%
Hence, sales associate obtain 40% of 125 = 50

A cylinder an a cone have the same volume.The cylinder has a radius of 2 inches and a height of 3 inches.The cone has a radius of 3 inches . What is the height of the Cone?
Volume of a cone = (1/3) pi x r^2 x h
Volume of a cylinder = pi x r^2 x h
Volume of the cylinder = pi x 2^2 x 3 = 37.68 cubic inches
Now set the volume for the cone to the volume of the cylinder and solve for the height.
37.68 = (1/3) x pi x r^2 x h
37.68 = (1/3) x pi x 3^2 x h
37.68 = (1/3) x pi x 9 x h
37.68 = 9.42 x h
h = 37.68 / 9.42
h = 4
The height of the cone is 4 cm.
What is the solution to the inequality 2n+5| > 1?
Answer:
n < - 3 or n > - 2
Step-by-step explanation:
Inequalities of the type | x | > a , have solutions of the form
x < - a or x > a
Then
2n + 5 < - 1 or 2n + 5 > 1
Solve both inequalities
2n + 5 < - 1 ( subtract 5 from both sides )
2n < - 6 ( divide both sides by 2 )
n < - 3
OR
2n + 5 > 1 ( subtract 5 from both sides )
2n > - 4 ( divide both sides by 2 )
n > - 2
Solution is n < - 3 or n > - 2
Solve the equation -3(x-14)+9x=6x+42. Does the equation have one solution, no solution, or infinitely many solutions?
Answer:
-3x+42+9x=6x+42
0x=0
x=0
Step-by-step explanation:
there is no solution
Answer:
infinitely many solutions
Step-by-step explanation:
Given
- 3(x - 14) + 9x = 6x + 42 ← distribute and simplify left side
- 3x + 42 + 9x = 6x + 42
6x + 42 = 6x + 42
Since the equation is the same on both sides, then any real value of x is a solution.
That is has infinite solutions
How do you know from a graph if a relationship is a direct variation?
Answer:
A direct variation is when x and y (or f(x) and x) are directly proportional to each other... For example, if you have a chart that says x and y, and in the x column is 1, 2 and 3, and the y column says 2, 4 and 6... then you know it's proportional because for each x, y increases by 2
Step-by-step explanation:
In the given figure, O is the centre of the circle. For
what values of x and y , chord BC will pass through
the centre of circle where points A, B and C are on
the circle?
(a) x = 90, y = 60 (b) x =75,y= 30
(c) x = 65, y = 90 (d) x =90, y = 65
Answer:
d
Step-by-step explanation:
If chord BC passes through the centre then it is a diameter . then
∠ BAC is the angle in a semicircle and x = 90°
y = 180° - (90 + 25) ← angle sum in a triangle
y = 180° - 115° = 65°
Thus
x = 90°, y = 65° → d
In this exercise we have to use the knowledge of triangles inscribed in a circle, in this way it will be possible to calculate the angles, then:
Letter D
Knowing that it is a triangle inscribed in a circle, in this way we can describe it as:
BAC is the angle in a semicircle and x = 90°Angle sum in a triangle is [tex]y = 180 - (90 + 25)[/tex]So:
[tex]y = 180 - 115 = 65\\ x = 90\\ y = 65 [/tex]
