If the car uses 3 1/8 gallons per hour and the number of hours is 4 2/3, we can multiply both values to find the total amount of gallons used in this time.

First, we need to convert 3 1/8 and 4 2/3 into improper fractions:

Now, multiplying the values, we have:

So the car will use 14.58 gallons.

Answer:

-7/10

Step-by-step explanation:

First, we obviously need to convert 0.66 into a fraction.  Since -7/10 cannot be changed, we need to change AND simplify -0.66.

-0.66 is equal to -66/100, but we can still simplify this. We can divide the numerator and denominator by 2.

66 divided by 2 is 33.

100 divided by 2 is 50.

-33/50 CANNOT be simplified anymore.

So -7/10 _ -33/50. Which is greater?

-7/10 is closer to 0 on the number line. -33/50 isnt.

So -7/10 is the answer.

-7/10 > -0.66

The limitations for modeling the problem are as follows: The gap between the number of hours Savanah has reserved and those that John has is no more than five times.

Savanah will provide child care for a minimum of 40 hours, but no longer than that, indicating that it is less than; as a result.

What is data?

Data, which can describe quantity, quality, fact, statistics, other fundamental units of meaning, or simply sequences of symbols that can be further interpreted, is a collection of discrete values that convey information in the pursuit of knowledge. A datum is a distinct state within a collection of data. Typically, data is arranged into structures like tables that give it additional context and meaning and can also be used as their own form of data in larger structures. It's possible to use data as variables in a computation. Data can represent both concrete measurements and abstract concepts. Data is used frequently in virtually every aspect of human organisational activity, including finance and science. Stock prices, crime rates, unemployment rates, literacy rates, and census data are a few examples of data sets.

Mode = 98 ( 98 occurs two times)

World renowned for the chocolate they produce, it seems the Swiss themselves can’t get enough of the candy. Germany, the country’s neighbor, is equally addicted, importing the largest share of Swiss chocolate of all countries in the world.

Step-by-step explanation:

Answer: a swede would consume 1.9 times as much chocolate as an American.

The equation of the time she can afford to park her car is 2 + 3t = N

The given parameters are

Assume she stays for t number of hours, the total charges would be

Total = Entrance charge + Rate per hour * Number of hours

This gives

Total = Entrance charge + Rate per hour * t

Substitute the known values in the above equation

So, we have

Total = 2 + 3t

From the question, she has N dollars

So, we have

2 + 3t = N

Hence, the expression of the description is 2 + 3t = N

What is GCF?

The biggest positive integer m that divides both x and y is the GCF of two or more non-zero integers, x, and y. The GCF stands for greatest common factor. In this case, greatest can be changed to highest, and factor to divisor. The highest common factor is often referred to as the biggest common factor, highest common factor, or highest common divisor (GCD). GCF is usually always utilised with fractions, which are frequently employed in daily life. You can obtain the necessary reduced form by determining the GCF of the denominator and numerator of a fraction or ratio.

A crane has a cable with a breaking strain of 6400 kg  measured to 2 significant figures.  It is used to lift crates which weigh 90 kg measured to the nearest 10 kg.

We need to calculate the greatest number of crates that can safely be lifted at one time without breaking the cable.

According to the question,

It is given that, the breaking strain of the crane is 6,400 kilograms and each crate is 90 kilograms.

Thus, to know the number of crates (n) that can safely lift is equal to the weight of the crane is 6,400 kilograms divided by is 90 kilograms.

thus,

Given expression is (a+b)^8 and we need to find the 5th term of this series.

Explanation -

The general binomial expression is given as

So the given expression can be written as

So the 5th term will be

Then we have

The non-real solutions are (2 + i√26)/3 and  (2 - i√26)/3

The equation of the polynomial expression is given as:

3x^3 + 14x^2 - 14x + 60 = 0

From the question, we have

x = -6

This gives

So, we have

x + 6 = 0

The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0

This is represented as

3x^3 + 14x^2 - 14x + 60/x + 6

Using a graphing calculator, we have

3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10

Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula

So, we have

x = (-b ± √(b² - 4ac))/2a

This gives

x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3

So, we have

x = (4 ± √-104)/6

This gives

x = (4 ± 2√-26)/6

Divide

x = (2 ± √-26)/3

Rewrite as

x = (2 ± i√26)/3

Split

x = (2 + i√26)/3 and  x = (2 - i√26)/3

Hence, the non-real solutions of the polynomial expression are x = (2 + i√26)/3 and  x = (2 - i√26)/3

No, they will not have the same amount in their account at any point of time.

Money deposited by Rodney each month in the account = $ 40

Money deposited by Morgan at the opening of savings account = $ 50

Money deposited by Morgan each month in the account = $ 40

Let us imagine that they will have equal amount of money in their accounts at a particular point of time.

Let us consider x to be the number of months when they will have same amount of money in their account.

Hence, we can write,

Explanation:

The unique digits are: 9, 6, 1

There are 1+3+3 = 7 digits with the repeats mentioned. If we could somehow tell the 6's apart and the 1's apart, then we'd have 7! = 7*6*5*4*3*2*1 = 5040 different permutations.

But because we can't tell the 6's apart, nor the 1's apart, this means we have to divide by (3!*3!). Each 3! represents the number of times the 6's show up and same goes for the 1's.

So (5040)/(3!*3!) = 5040/(6*6) = 5040/36 = 140 is the number of ways to rearrange the digits
