It will take (miles / (mph eastbound + mph westbound)) hours for the two trains to be miles apart.

(miles / (mph eastbound + mph westbound)) * 60 minutes/hour = minutes

The time it takes for two trains to be a certain distance apart depends on the speed of each train and the distance between them. To calculate this, we can use the equation time = distance/speed. We can also use this equation to calculate the time for two trains traveling in opposite directions. To do this, we add the speed of the eastbound train (mph eastbound) and the speed of the westbound train (mph westbound) and divide the distance between the two trains (miles) by the total. This gives us the amount of time it will take for the two trains to be miles apart. After converting the answer to minutes, we get the amount of time it will take for the two trains to be miles apart.

To find the height of a stack of 8x10^9 books, we need to calculate the total thickness of all the books.

The thickness of one book is 3.1x10^-4 meters. So, the total thickness of 8x10^9 books can be calculated by multiplying the thickness of one book by the number of books:

3.1x10^-4 meters/book * 8x10^9 books = 24.8 meters

Therefore, the height of a stack of 8x10^9 books, each with a thickness of 3.1x10^-4 meters, would be 24.8 meters.

It's equivalent to about 81 ft.

The required value of the given function is (f ⋅ g)(4) = 130.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question, as follows:

Answer: Apples $0.18 (18 Cents) Bananas $0.14 (14 cents)

Step-by-step explanation:

Math knowledge would give the cost for each item. We have:

4 apples + 6 bananas = $1.56

and

9 apples + 7 bananas = $2.60

To find a cost, we encode an apple as 'a', and a banana as 'b' in the following two main equations:

4a+6b=1.56

9a+7b=2.6

The following formula represents the situation by using elimination method to find, let's say, the banana value:

4a+6b=1.56 , 9a+7b=2.6

9×4a+9×6b=9×1.56, 4×9a+4×7b=4×2.6

36a+54b=14.04, 36a+28b=10.4

36a−36a+54b−28b=14.04−10.4

54b−28b=14.04−10.4

26b=14.04−10.4

26b=3.64

b=3.64÷26

b=0.14

That is a banana costs $0.14 (14¢).

Now we have found the value of a banana, we substitute this new value in one of the main equations above to reduce variables so that we can find the value of an apple as follows:

4a+6b=1.56

4a+(6×0.14)=1.56

4a+0.84=1.56

4a=1.56-0.84

4a=0.72

a=0.72÷4

a=0.18

Simply enough, an apple costs $0.18 (18¢), and a banana costs $0.14 (14¢).

According to the information, we can infer that there are 20 games left. To solve this problem we have to use a linear equation.

To calculate how many games do the Rockets have left to play we have to use a linear equation. Additionally, we have to take into account the information that we have:

Also, we know that if the rockets loses all the remaining games, and the rangers win all the remaining games, both will win the same number of games. Finally, to solve this problem we have to make the following equation:

In this equation, X is equal to the number of games won by both teams.

(100 - X)*(7/20) + X = (100 - X)*(3/5)

X = (100 - X)*(3/5) - (100 - X)*(7/20)

X = (100 - X)*(3/5 - 7/20)

X = (100 - X)*(12/20 - 7/20)

X = (100 - X)*(5/20)

(20/5)*X = 100 - X

4*X = 100 - X

4*X + X = 100

5*X = 100

X = 100/5

X = 20

Shares of businesses having a market value between $300 million and $2 billion are considered small-cap stocks. Small-cap firms have the potential for rapid development, which makes them attractive investment targets even if their stocks may be more volatile and carry greater risks for buyers.

Large-cap stocks, commonly referred to as large caps, are stocks that are traded for businesses with a market value of at least $10 billion. Because investors gravitate toward quality and stability and become more risk-averse during challenging markets, large-cap companies often exhibit lower volatility.

Answer:

a) To find out how much money is added to the account each year, we use the simple interest formula: I = Prt, where I is the interest, P is the principal (initial deposit), r is the annual interest rate (expressed as a decimal), and t is the number of years.

In this case, P = 1800, r = 0.03, and t = 1 (because we are finding the interest added for 1 year)

So the formula becomes:

I = 1800 * 0.03 * 1 = 54

Therefore, £54 is added to the account each year.

b) To find out how much money will be in the account after two years, we add the original deposit to the total interest earned over two years.

We know that the interest added each year is £54, and since we are trying to find the balance after 2 years, we will multiply it by 2 to find the total interest earned over 2 years:

Interest = 54 * 2 = £108

Now we add the original deposit and the total interest to find the total amount in the account after 2 years:

Total = 1800 + 108 = £1908

So the amount of money in the account after two years will be £1908.

The account will have £1909.62 after two years.

Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

a) The amount of money added to the account each year is determined by multiplying the principal amount (initial amount) by the interest rate. So, the amount added to the account each year is:

Interest = Principal x Rate

Interest = £1800 x 0.03

Interest = £54

Therefore, £54 will be added to the account each year.

b) To find the amount of money in the account after two years, we need to add the interest earned in each year to the principal amount. After one year, the account will have:

Amount after 1 year = £1800 + £54 = £1854

After the second year, the account will have earned another 3% interest on the new balance of £1854. So, the interest earned in the second year is:

Interest = £1854 x 0.03

Interest = £55.62

Therefore, the total amount of money in the account after two years is:

Amount after 2 years = £1854 + £55.62 = £1909.62

So, the account will have £1909.62 after two years.

The cost of one hundred kilowatt-hours of electricity is $16.4

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, the formula for calculating the cost per one thousand kilowatt-hours of electricity is twice the sum of 36 and 4 times the difference of 7 and 2 dollars per thousand kilowatt-hours.

The cost for 1000 kilowatt-hours of electricity =

2(36+36) + 4(7-2)

= 2(72) + 4(5)

= 144 + 20

= $164

Since, 1000 kilowatt-hours of electricity costs $164

Then, 1 kwh will cost = $164 / 1000

And, 100 KWh will cost = $164 / 1000 × 100

= $16.4

The area of the shaded portion is given by the difference between the area of the outer circle and the area of the inner circle.

First, let's find the areas of the circles:

Outer Circle: Area = πr^2 = π (2)^2 = 4π square meters

Inner Circle: Area = πr^2 = π (0.75)^2 = 0.5625π square meters

Area of shaded portion = Area of outer circle - Area of inner circle = 4π - 0.5625π = 3.4375π square meters
