Answer:
10.2 years
gain is $2,704.00
rate of return is 22%
Step-by-step explanation:
The it would take for mutual to double can be determined the future value formula as shown below:
=nper(rate,pmt,-pv,fv)
rate is the rate of return of 7% per year
pmt is the periodic amount placed in the mutual fund and it not applicable here
pv is the original amount invested which is $7,500
fv is the future worth of $15,000
=nper(7%,0,-7500,15000)=10.2 years
cost of shares=actual cost of purchase+broker's commission
=(800*$15.34)+$20=$12,292.00
gain on shares=sales proceeds-cost=(800*$18.77)-$20-$12,292.00=$2,704.00
rate of return=gain/original cost=$2,704.00/$12,292.00 =22%
Find the midpoint of the segment with endpoints (-3,4) and (7,10)
Answer:
(2,7)
Step-by-step explanation:
To find the midpoint, you need to plug the 2 points in to the midpoint formula.
[tex]( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )[/tex]. You are basically adding the x values and divided the sum by 2 and doing the same for the y values. To find the x value of the midpoint, you add -3 and 7 which gets you 4, then you divide by 2 which is 2. To find the y value of the midpoint you, you add 4 and 10 which gets you 14, then you divide by 2 which gets you 7. So your mid point is (2,7).

A basketball with a diameter of 9.5 in. is placed in a cubic box with sides 15 in. long. How many cubic inches of packing foam are needed to fill the rest of the box? Round to the nearest tenth.
Answer:
2926.32 cubic inches
Step-by-step explanation:
Given the information:
A basketball with a diameter of 9.5 in=> its radius is: 9.5/2 = 4.75 in
As we know, the formula used to find the volume of the sphere is:
V =π [tex]\frac{4}{3} r^{3}[/tex]
=> the volume of the basketball is:
V = π [tex]\frac{4}{3} 4.75^{3}[/tex]
= 448.69 cubic inches
A cubic box with sides 15 inAs we know, the formula used to find the volume of a cube is:
V = [tex]a^{3}[/tex]
=> the volume of the box:
V = [tex]15^{3}[/tex] = 3375 cubic inches
Hence, The volume of foam there is needed to complete the box is the subtraction between the two volumes above:
= the volume of the box - the volume of the basketball
= 3375 - 448.69
= 2926.32 cubic inches

George has opened a new store and he is monitoring its success closely.
He has found that this store’s revenue each month can be modeled by r(x)=x2+6x+10 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars.
He has also found that his expenses each month can be modeled by c(x)=x2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars.
What does (r−c)(4) mean about George's new store?
The new store will have a profit of $2300 after its fourth month in business.
The new store will sell 4500 items in its fourth month in business.
The new store will have a profit of $4500 after its fourth month in business.
The new store will sell 2300 items in its fourth month in business.
Answer:
It will be 4500
Step-by-step explanation:
Just substitute 4 for x in both equations and you will get:
r(4) = $5,000 store's revenues in 4 months
c(4) = $500 store's expenses in 4 months.
So, (r - c) = $5,000 - $500 =$4,500 store's profit after 4 months in business.

You want to take group fitness classes at a nearby gym, but needs to start by selecting a membership plan. With the first membership plan, you can pay $20 per month, plus a $60 signing fee. With the second membership plan, you can pay $40 per month plus no signing fee. At what number of months will both plans cost the same amount?
Answer:
after 3 months, both plans cost the same amount
Step-by-step explanation:
Let x is the number of monthsLet y is the total costGiven the following information:
Plan 1: pay $20 per month, plus a $60 signing fee
=> the equation for this plan is:
y1 = 20x+60
Plan 2: pay $40 per month plus no signing fee
=> the equation for this plan is:
y2 = 40x
To find number of months will both plans cost the same amount, we need to set the equation of plan 1 = equation of plan 2
<=> y1 = y2
<=> 20x+60 = 40x
<=> 20x = 60
<=> x = 3
So after 3 months, both plans cost the same amount
A restaurant has 4 appetizers, 5 entrees and 2 desserts. How many different meal combinations could you order?
Step-by-step explanation:
1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things
2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!
3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!

The length of a field, 1.2 km long is represented on a map by a line 40mm long. What is the scale of the map
Final answer:
The scale of the map is 1:30,000.
Explanation:
The scale of a map represents the relationship between the distance on the map and the corresponding distance on the Earth's surface. To find the scale of the map, we need to determine the ratio between the length of the field on the map and its actual length. In this case, the length of the field is 1.2 km, which is represented on the map by a line that is 40 mm long.
To calculate the scale, we can use the formula:
Scale = Actual length on the ground / Length on the map
Substituting the values, we get:
Scale = 1.2 km / 40 mm
First, we need to convert the length on the map to the same unit as the actual length. Since 1 km = 1,000,000 mm, we can convert mm to km by multiplying by 1/1,000,000:
Length on the map in km = 40 mm × (1 km / 1,000,000 mm) = 0.00004 km
Now we can calculate the scale:
Scale = 1.2 km / 0.00004 km = 30,000
Therefore, the scale of the map is 1:30,000.
