They will have the same amount of money in their bank accounts after 26 months.
What is algebra ?Algebra is the branch of mathematics that uses letters and variables to represent the missing information in a given mathematical expression, to find the solution.
Here,
Amount of money added by Neil in January = £32
Amount of money added by Amber in January = £240
Amount of money added by Neil at the end of every month = £50
Amount of money added by Amber at the end of every month = £42
According to the given data, after a number of months, the amount of money in their bank accounts must become same.
Let n be the number of months,
(£32 + n£50) = (£240 + n£42)
n£50 - n£42 = £240 - £32
n£8 = £208
So, n = 208/8
n = 26
Hence,
They will have the same amount of money in their bank accounts after 26 months.

2. 226.08in³.
3. 392.50cm³.
4. 4186.66in³.
5. 395.64ft³
6. 235.50cm³.
Define volume?A three-dimensional solid shape's volume is the area it takes up in space. Though it is challenging to picture in any shape, it can be contrasted with others. A compass box, for example, has a bigger volume than one that has an eraser inside of it.
The area of every two-dimensional form is calculated by dividing it into equal square units. We will do something similar to calculate the volume of solid things by dividing it into equal cubical units.
In the given question,
Volume of the sphere is: 4/3πr³.
Radius, r is = 6m.
Volume = (4× 3.14 × 6³)/3
= 904.32m³.
Volume of the cylinder is: πr²h.
Radius, r = 3in.
Height, h = 8in.
Volume = 3.14 × 3² × 8
= 226.08in³.
Volume of cone = 1/3 πr²h
Radius, r = 5cm.
Height, h = 15cm.
Volume = (1 × 3.14 × 5² × 15)/3
= 392.50cm³.
Again, we have a sphere, with d = 20in.
R = d/2
= 20/2
=10in
Volume = 4/3πr³.
= (4 × 3.14 × 10³)/3
= 4186.66in³.
Again, we have a cylinder with r = 3ft and h = 14ft.
Volume = πr²h.
= 3.14 × 3² × 14
= 395.64ft³
Lastly, we have another cone of r = 5cm and h = 9cm.
Volume = 1/3 πr²h
= (1 × 3.14 × 5² × 9)/3
= 235.50cm³.

Part P
You’ve just completed three long division calculations. What can you conclude about the quotient, or result, from the long division process? Does it end or does it continue indefinitely?
Please help i'm so confused!
Answer:
Part A
The volume of solution A is represented as a fraction, so we need to convert it to a decimal number. To do this, we set up a long division problem with the numerator (the top number in the fraction) as the dividend and the denominator (the bottom number in the fraction) as the divisor. So the dividend is 1, and the divisor is the volume of solution A.
Part B
No, we cannot divide 2 by 9 evenly because they are not divisible without a remainder.
Part C
Since we cannot divide 2 by 9 evenly, the first digit of the quotient will be 0.
Part D
We set up the long division problem as follows:
0.2 7 7 7 7 ...
-------------
9 | 1.0000
- 0.9
-----
1 0 0
9 0

-----
1 0 0 0 0
9 0
-----
1 0 0 0 0
The decimal equivalent of 2/9 is 0.27777... (repeating). We can see that the division process continues indefinitely with the same repeating pattern, so we use an ellipsis to indicate that the pattern continues infinitely.
Part E
If we keep repeating the long division process for 2/9, we will continue to get the same repeating decimal pattern of 0.27777..., with no end in sight.
Part F
The volume of solution B is represented as the fraction 3/8, so we need to convert it to a decimal number. To do this, we set up a long division problem with the numerator (3) as the dividend and the denominator (8) as the divisor.
Part G
No, we cannot divide 3 by 8 evenly because they are not divisible without a remainder.
Part H
Since we cannot divide 3 by 8 evenly, the first digit of the quotient will be 0.
Part I
We set up the long division problem as follows:
0.3 7 5
---------
8 | 3.0000
- 2.4
----
6 0
5 6

---
2 8 0
2 4
---
4 0
The decimal equivalent of 3/8 is 0.375. We can see that the division process terminates after a finite number of decimal places.
Part J
If we keep repeating the division process for 0.375, we will always get the same decimal number because the process terminates and doesn't involve any repeating pattern.
Part K
The volume of solution C is represented as the fraction 1/5, so we need to convert it to a decimal number. To do this, we set up a long division problem with the numerator (1) as the dividend and the denominator (5) as the divisor.
Part L
No, we cannot divide 1 by 5 evenly because they are not divisible without a remainder.
Part M
Since we cannot divide 1 by 5 evenly, the first digit of the quotient will be 0.

which of these numbers of different license plates can be determined using only the product rule (without the use of the sum rule or some other rule)? (select all that apply.)
There can be 78,364,164,096 different license plates created if there are 7 numbers or letters on the plate, determined using the product rule.
We can use the product rule to determine the number of different license plates that can be created if there are 7 numbers or letters on the plate.
Assuming that each position on the license plate can be filled with any number or letter, we can use the multiplication principle to find the total number of possibilities. For each position, there are 26 letters and 10 digits to choose from (assuming the use of the English alphabet), so there are 36 choices for each position.
Therefore, the total number of different license plates that can be created is:
36 x 36 x 36 x 36 x 36 x 36 x 36 = 36^7
This simplifies to:
78,364,164,096
So there are 78,364,164,096 different license plates that can be created if there are 7 numbers or letters on the plate.

Step-by-step explanation:
I added a photo of my solution
Answer:
3m+2L = 7
4m + L = 6
Step-by-step explanation:
Let m = cost of the muffins
Let L = cost of the lattes
3m+2L = 7
4m + L = 6
To solve
Multiply the second equation by -2 and add them together.
3m+2L = 7
-8m + -2L = -12
-------------------------
-5m = -5
Divide by -5
-5m/-5 = -5/-5
m = 1
Then
4(1) +L = 6
L = 6-4
L =2
The solution is
muffins cost 1 dollar and lattes cost 2 dollars.
simultaneous equation x=5, y=1
The answer to the given problem is x = 3 and y = 1.
Define simultaneous equationSimultaneous equations are a set of equations with multiple variables that must be solved at the same time. In other words, they are equations that have more than one unknown value, and their solutions must satisfy all the equations in the system. These equations are used to model many real-world situations, such as business and engineering problems.
Given equation;
x + y = 4 ...................... (1)
2x - 5y = 1 ..................... (2)
Multiplying by 5 equation (1) we get,
5(x + y = 4)
5x + 5y = 20 ................. (3)
Adding equation (2) and (3) we get,
2x - 5y = 1
5x + 5y = 20
7x = 21
x = 21/7
x = 3
Putting x=3 in equation(2), we get
2x - 5y = 1
2(3) - 5y = 1
6 -5y =-5y = 1 - 6

Therefore, Dylan's initial investment was £1200.
What is simple interest?Simple interest is a type of interest that is calculated on the principal amount of a loan or investment. It is a fixed percentage of the original amount borrowed or invested that is added to the principal at regular intervals, usually monthly, quarterly or annually. The interest rate remains constant throughout the loan or investment term, and the interest earned or paid is calculated solely on the initial principal amount. Simple interest is commonly used for short-term loans or investments, and the formula for calculating it is straightforward:
by the question.
we can start by using the formula for simple interest:
Simple interest = Principal x Rate x Time
Where the Principal is the initial investment, the Rate is the annual interest rate, and the Time is the number of years.
We know that the Rate is 3% per annum and the Time is 2 years, so we can write:
Simple interest = Principal x 0.03 x 2
Since we are given that the value of the investment increased by £72 at the end of the 2-year period, we can set up an equation:
Value of investment - Initial investment = Simple interest
£72 = Principal x 0.03 x 2
£72 = Principal x 0.06
Principal = £72 / 0.06

What is a system of equations?A system of equations is a set of two or more equations that are formed by the same variable.
Each of the equations are solved as follows to determine whether it has no solution, one solution, or an infinite number of solutions
1. 2·x - 3·y = 3 and -4·x + 6·y = 6
Multiplying the first equation by 2, we get; 4·x - 6·y = 6.
Adding the above equation to the second equation,we get;
4·x - 6·y + (-4·x + 6·y) = 6 + 6 = 12
0 = 12 (False)
Therefore, the system has no solution
2. 3·x - 2·y = 3 and x + 2·y = 5
Adding the two equations, we get;
3·x - 2·y + (x + 2·y) = 3 + 5 = 8
4·x = 8
x = 8/4 = 2
Substituting x = 2 into the second equation, we get;
x + 2·y = 5
2 + 2·y = 5
2·y = 5 - 2 = 3
y = 3/2 = 1.5
y = 1.5
Therefore, the system has one solution
3. -8·x + 12·y = -12 and 2·x - 3·y = 3
Multiplying the second equation by 4, we get; 8·x - 12·y = 12
Adding the product of the second equation and 4 to the first equation we get;
8·x - 12·y + (-8·x + 12·y) = 12 + (-12) = 0
0 = 0
Therefore, the system has infinite number of solutions
4. y = -x + 2 and y = 3·x - 2
Substituting y = -x + 2 into the second equation, we get;
-x + 2 = 3·x - 2
3·x - 2 = -x + 2
3·x + x = 2 + 2 = 4
4·x = 4
x = 4/4 = 1
x = 1
y = -x + 2
y = -1 + 2 = 1
y = 1

The United States has a population of about 320 million, so if homicides were proportional to Honduras' rate of homicide, we would expect about 12,800 deaths due to homicides in the United States.
This is calculated by taking the population of the United States (320 million) and multiplying it by the Honduras' homicide rate of 40 per 100,000 people.
To calculate this, we first need to find Honduras' homicide rate. The World Bank has this information, which states that the rate is 40 per 100,000 people. We then need to take the population of the United States (320 million) and multiply it by the rate.
This equals 128 million homicides per 100,000 people in the United States. This comes out to 12,800 deaths due to homicides in the United States. Round this to the nearest person, and you get 12,800.

But total girls in college = 160 , so 5x= 160
solve the above expression (dividing by 5)=> x = 160/5 = 32
So, total boys students in college = 8x
= 8 × 32
= 256
Total number of students in college = 13x = 13× 32
= 416
Hence, required value is 416.

Let Y1 and Y2 have joint pdf
f(y1,y2)=3y1
, if 0≤y2≤y1≤1
0, otherwise.
a) Find the marginal density function for Y2.
b) For what values of y2 is the conditional density f(y1|y2)
defined?
a. The marginal density function for Y2 is fY2(y2) = 3y2², where 0 ≤ y2 ≤ 10.
b. For y2 ≤ y1 ≤ 10 of y2 is the conditional density f(y1|y2) is defined
(a) To find the marginal density function for Y2, we integrate the joint pdf over all possible values of Y1:
fY2(y2) = ∫fY1,Y2(y1,y2) dy1, where the integral is taken over the range where 0 ≤ y2 ≤ y1 ≤ 10, otherwise 0.
fY2(y2) = ∫₀¹⁰3y1 dy1 = 1.5y² |₀y2 = 1.5y2², where 0 ≤ y2 ≤ 10.
So the marginal density function for Y2 is:
fY2(y2) = 3y2², where 0 ≤ y2 ≤ 10.
(b) The conditional density f(y1|y2) is defined as:
f(y1|y2) = fY1,Y2(y1,y2) / fY2(y2), where fY2(y2) > 0.
So the conditional density is defined for all y1 such that 0 ≤ y2 ≤ y1 ≤ 10 and 0 ≤ y2 ≤ 10, i.e.,
y2 ≤ y1 ≤ 10.

Rosie bought a car for £4000. 3 years later, she sells it for £1400. What is the percentage loss that Rosie has made?
Answer:
65%
Step-by-step explanation:
Given data
Cost price= £4000
Selling price= £1400
% loss= cost price-selling price/cost*100
% loss= 4000-1400/4000*100
% loss= 2600/4000*100
% loss= 0.65*100
% loss= 65%
Hence the %loss is 65%

coach yamada is organizing community volleyball teams. he wants each team to have 8 players. unfortunately, coach yamada can't make as many full teams as he wanted to since fewer than 80 people signed up. let x represent how many full teams coach yamada can make. which inequality describes the problem?
The inequality that describes the problem when coach Yamada is organizing community volleyball teams is x ≤ 9.
Why is x ≤ 9 the correct inequality that describes the problem when coach Yamada is organizing community volleyball teams? Here is why: We know that coach Yamada wants each team to have 8 players but he can't make as many full teams as he wanted to because fewer than 80 people signed up.
Let x represent the number of full teams coach Yamada can make. We know that 1 team can have 8 players. Therefore, the number of players needed for x full teams = 8xWe also know that fewer than 80 people signed up. So, 8x < 80, if more than 80 people signed up then coach Yamada would be able to make more than x full teams.
Since coach Yamada can't make a fraction of a team so x should be an integer. Therefore, the solution for 8x < 80 is x ≤ 9.Therefore, x ≤ 9 is the inequality that describes the problem when coach Yamada is organizing community volleyball teams.
