A box of candy weighs 4 and 7/10 pounds. 2/5 get dumps out of the box. What is the weight of the candy left in the box?
2/5 get dumps out of the box from 4 and 7/10 pounds of candy then weight of the candy left in the box is 2 and [tex]\frac{41}{50}[/tex] pounds.
As given,
Total weight of the candy = 4 and 7/10 pounds = [tex]\frac{47}{10\\}[/tex] pounds
pound is the imperial unit of weight generally written as lb.
one pound = 0.4535 kilograms = 453.5 gm.
[tex]\frac{2}{5}[/tex] th of candy is dumps out of the box.
1- [tex]\frac{2}{5}[/tex] = [tex]\frac{3}{5}[/tex] th of the total candy is left in the box.
weight of the candy left in the box = [tex]\frac{3}{5}[/tex] * [tex]\frac{47}{10}[/tex] = [tex]\frac{141}{50}[/tex] pounds.
now 141= 50*2 + 41
[tex]\frac{141}{50}[/tex] pound = 2 and [tex]\frac{41}{50}[/tex] pounds
Hence, weight of the candy left in the box= 2 and [tex]\frac{41}{50}[/tex] pounds.

11 ft
7 ft 8 ft
20 ft What is the area of the shape?
Answer:
Area = 192.5 ft.²
Step-by-step explanation:
By splitting the shape in 2, we can find the area much simpler.
Starting with the parallelogram (on the left), the area formula is A = b × h.
b (base) = 11 ft.
h (height) = 7 ft.
A (area) = (11 ft.)(7 ft.)
A = 77 ft.² (save this for later)
Then, the trapezoid's (on the right) area formula is A = [(a + b) ÷ 2] × h.
a (first base) = 8 ft.
b (second base) = (20 - 7) = 13 ft.
h (height) = 11 ft.
A = [(8 ft. + 13 ft.) ÷ 2] × 11 ft.
A = [(21 ft.) ÷ 2] × 11 ft.
A = (10.5 ft.) × 11 ft.
A = 115.5 ft.²
Now, bringing back the first area, we can add them together to find the total:
A = 77 ft.² + 115.5 ft.²
A = 192.5 ft.²

Based on the fact that the widow got an exemption on homestead tax, the amount that the owner would pay in property taxes is $3,471.20.
What is the property tax?The widow received a homestead tax exemption of $25,000 on the property.
The amount to be paid in property tax is:
= (8.8 + 9.3 + 6.5) / 1,000 x (185,000 - 25,000)

A customer paid a total of $6.00 for 68 copies at a print shop. Some of the copies were black-and-white copies, and the rest were color copies.
• Each black-and-white copy cost $0.08.
• Each color copy cost $0.15.
How many copies of b, the number of black-and-white, and c, the number of color did the customer pay for?
The number of black-and-white is 60 and the number of color copies is 8.
How to calculate the value?Let b = the number of black-and-white.
Let c = the number of color copies.
The equation will be:
b + c = 68
0.08b + 0.15c = 6
Multiply equation I by 0.08
Multiply equation ii by 1.
0.08c + 0.08c = 5.44
0.08b + 0.15c = 6
Subtract
0.07c = 0.56
c = 0.56/0.07
c = 8
Since b + c =68
b= 68 - 8 = 60
Therefore, the number of black-and-white is 60 and the number of color copies is 8.

Michael grabs a marble from a bag. There are 5 green marbles and 1 red marble. If he grabs the red marble he loses everything he bet on. The marbles are not put back into the bag. The max amount of times Michael can bet on the same game is 4. If he bets 300 and wins 578 (having 278 as winnings), he has the choice to bet again with everything he earned for 682. Then he has the choice to do so again for 945, then 1312 at max. At what point in the game should Michael stop playing to gain the most given the percent of risk of losing the game? What point in the game is the least beneficial for Michael's gains?
First bet (300 -> 578)
Second bet (578 -> 682)
Third bet (682 -> 945)
Fourth bet (945 -> 1312)
If Michael wins every round he would go from 300 to 1312. If he loses, he doesn't gain any of the rewards and is 300 in debt.
Using the expected value of a discrete distribution, it is found that:
Michael should stop playing the game after the first round.The fourth round is the least beneficial round for Michael.What is the mean of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
For the probabilities, we consider that it is given by the number of desired outcomes divided by the number of total outcomes.
For one bet, the distribution is given as follows:
P(X = 578) = 5/6 (5 green marbles out of 6).P(X = -300) = 1/6.Hence the expected value is given by:
E(X) = 578 x 5/6 - 300 x 1/6 = $431.67.
For two bets, the distribution is given as follows:
P(X = 682) = 5/6 x 4/5 = 2/3.P(X = -300) = 1/3.Hence the expected value is given by:
E(X) = 682 x 2/3 - 300 x 1/3 = $354.67.
For three bets, the distribution is given as follows:
P(X = 945) = 5/6 x 4/5 x 3/4 = 1/2.P(X = -300) = 1/2.Hence the expected value is given by:
E(X) = 945 x 1/2 - 300 x 1/2 = $322.5.
For four bets, the distribution is given as follows:
P(X = 1312) = 5/6 x 4/5 x 3/4 x 2/3 = 1/3.P(X = -300) = 2/3.Hence the expected value is given by:
E(X) = 1312 x 1/3 - 300 x 2/3 = $237.33.
Hence, considering the greatest and the smallest expected values, we have that:

Colin is borrowing money from his parents to purchase a $700
computer. He will pay them $35 per month for two years. Determine the
simple interest rate on Colin's loan.
Colin paid the loan at a ten percent annual interest rate.
Simple interest is the form of interest calculation in which the principal amount remains the same for the entire duration for which the loan is taken.
It is also assumed that Colin will repay $35 per month for the next two years.
We must calculate a simple interest rate on Colin's borrowings.
As a result, Colin's total payment to his parents for two years is $35.
We are required to find simple interest rate on Colin's borrowings
Therefore, total amount paid by Colin to his parents= 35$ for 2 years
=35*24=840
The amount paid by Colin is principal + interest
Thus, the simple interest amount= 840-700=140$
We know that the simple interest formula is principal*rate*time/100.
We know that the simple interest is 140, the principal is 700, the time is two years, and we need to find the rate of interest.
SI= P*R*T/100
140= 700*R*2/100
140/7*2=R
R=140/14=10
Therefore, The Rate of interest on which Colin paid the loan is 10 per cent per annum

2x-y+2z=-6
-3y+z=-2
2x-3z+4
The solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7
How to solve the system of equations?The system of equations is given as
2x - y + 2z = -6
-3y + z = -2
2x - 3z = -4
Subtract 2x - 3z = -4 from 2x - y + 2z = -6
This is represented as
(2x - y + 2z = -6) - (2x - 3z = -4)
This gives
- y + 5z = -2
Multiply - y + 5z = -2 by 3
-3y + 15z = -6
Subtract -3y + 15z = -6 from -3y + z = -2
This is represented as
(-3y + z = -2) - (-3y + 15z = -6)
This gives
-14z = 4
Divide by -14
z = -2/7
Substitute z = -2/7 in - y + 5z = -2
- y - 5 * 2/7 = -2
This gives
- y - 10/7 = -2
Rewrite as:
y = 2 - 10/7
Evaluate
y = 4/7
Substitute z = -2/7 in 2x - 3z = -4
2x - 3 * 4/7 = -4
This gives
2x - 12/7 = -4
So, we have:
2x = 12/7 - 4
Evaluate
2x = -16/7
Divide by 2
x = -8/7
Hence, the solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7
