Jasmine's race time was 34.287 minutes. Round her race time to the nearest tenth of a minute.

Answers

For this case, the first thing we must take into account is the following rounding rules:

  • 1) If the decimal prior to the number to be rounded is greater than or equal to five, then the next number increases by one unit.
  • 2) If the decimal prior to the number to be rounded is less than five, then the next number remains the same.

We then have the following decimal:

34.287

Rounding to the nearest tenth of a minute we have:

34.3

Answer:

her race time to the nearest tenth of a minute is:

34.3

What is the Volume of 10g of Gasoline?

Answers

Answer:

The Volume of 10 g of Gasoline is 14.286 ml approximately.

Step-by-step explanation:

Consider the provided information.

We need to find the Volume of 10 g of Gasoline.

Solve this with using the formula shown below:

Volume = mass/density

The density of gasoline is 0.7 g/ml.

Substitute the respective values in the above formula as shown:

Volume=(10)/(0.7)

Volume=(100)/(7)

Volume=14.286

Hence, the Volume of 10 g of Gasoline is 14.286 ml approximately.

10g /(0.7 g/ml) = 100/7 ml 

= 14.2857... 

Or 14.29 ml 

Add.Your answer should be an expanded polynomial in standard form.
(-t^4 – 5t^3– 10t^2) + (9t^3+ 3t^2– 1) =

Answers

According to given question, The simplified polynomial in standard form is: -t^4 + 4t^3 - 7t^2 - 1

To add the two polynomials and simplify, we'll combine like terms:

(-t^4 - 5t^3 - 10t^2) + (9t^3 + 3t^2 - 1)

In mathematics, a polynomial is an algebraic expression consisting of variables (also known as indeterminates) and coefficients, combined using addition, subtraction, and multiplication operations. The variables are raised to non-negative integer powers, and the coefficients are constants that multiply the variables. The term "polynomial" comes from the Latin words "poly" (meaning "many") and "nomial" (meaning "term").

Step 1: Combine the terms witht^4 and t^3:

(-t^4) + (9t^3 - 5t^3) - 10t^2 + 3t^2 - 1

Step 2: Combine the t^3 terms and the t^2 terms:

(-t^4) + (4t^3) - 7t^2 - 1

So the simplified polynomial in standard form is:

-t^4 + 4t^3 - 7t^2 - 1

Twenty-two is what percent of 55?A.
22%

B.
40%

C.
250%

D.
50%

Answers

Answer:

Option B is correct.

Twenty-two is 40 percent of 55

Step-by-step explanation:

Let x be the number.

As per the statement:

Twenty-two is x percent of 55

Solve for x:

Twenty-two is x percent of 55

"of" means multiply

22 = (x)/(100) * 55

Divide both sides by 55 we get;

(22)/(55) = (x)/(100)

Simplify:

(2)/(5) = (x)/(100)

Multiply both sides by 100 we have;l

x = (2)/(5) * 100

Simplify:

x = 40%

Therefore, Twenty-two is 40 percent of 55

To find the percentage
that 22 is for the actual number 55 = (22/55) * 100
                                                        = (2/5) * 100
                                                        = 2 * 20
                                                        = 40 percent
So the correct option among all the options given in the question is option "B".Most of the information’s that are required for solving thisproblem is already given in the question. I hope the procedure for solving theproblem is also clear for you to understand. In future you can always use thismethod for solving similar problems.
