The correct option is C. 3 ÷ 1 > 3 ÷ 3.

To solve this problem, we need to evaluate each of the given number sentences to determine which one is true.

A. 3 ÷ 1 < 0 ÷ 3

First, we perform the divisions:

3 ÷ 1 = 3

0 ÷ 3 = 0

Now we compare the results:

3 < 0

This statement is false because 3 is not less than 0.

B. 0 ÷ 3 > 3 ÷ 3

Again, we perform the divisions:

0 ÷ 3 = 0

3 ÷ 3 = 1

Now we compare the results:

0 > 1

This statement is false because 0 is not greater than 1.

C. 3 ÷ 1 > 3 ÷ 3

We perform the divisions:

3 ÷ 1 = 3

3 ÷ 3 = 1

Now we compare the results:

3 > 1

This statement is true because 3 is greater than 1.

D. 3 ÷ 3 < 4 ÷ 4

We perform the divisions:

3 ÷ 3 = 1

4 ÷ 4 = 1

Now we compare the results:

1 < 1

This statement is false because 1 is not less than 1; they are equal.

Therefore, the only true statement is C. 3 ÷ 1 > 3 ÷ 3.

The required, 5.241 divided by 3 equals approximately 1.747.

To divide 5.241 by 3, we can perform the division as follows:

    1.747

------------

3 | 5.241

To start, we divide the whole number part, 5, by 3. The result is 1, which becomes the whole number part of the quotient.

Next, we bring down the decimal point and consider the decimal part of the dividend, which is 0.241. We can continue the division process by adding a decimal point to the quotient and placing a 0 to the right of the decimal point.

   1.747

 3 | 5.241

     - 3

     -----

       24

Now, we divide 24 by 3, which gives us 8. We bring down the next decimal digit, which is 1, and continue the division:

   1.747

 3 | 5.241

     - 3

      -----

       24

     - 24

      -----

         1

Since there are no more decimal digits to bring down, we have finished the division. The final quotient is 1.747, rounded to three decimal places.

Therefore, 5.241 divided by 3 equals approximately 1.747.

Answer:

Step-by-step explanation:

Using the Remainder theorem

If f(x) is divided by (x - h) then f(h) = remainder, thus

f(3) = 3³ + a(3)² + b(3) + 4 = 10, that is

27 + 9a + 3b + 4 = 10

9a + 3b + 31 = 10 ( subtract 31 from both sides )

9a + 3b = - 21 → (1)

f(- 1) = (- 1)³ + a(- 1)² + b(- 1) + 4 = 6, that is

- 1 + a - b + 4 = 6

a - b + 3 = 6 ( subtract 3 from both sides )

a - b = 3 → (2)

Rearrange (2) expressing a in terms of b

a = 3 + b → (3)

Substitute a = 3 + b into (1)

9(3 + b) + 3b = - 21 ← distribute and simplify left side

27 + 9b + 3b = - 21

12b + 27 = - 21 ( subtract 27 from both sides )

12b = - 48 ( divide both sides by 12 )

b = - 4

Substitute b = - 4 into (3)

a = 3 - 4 = - 1

Hence a = - 1 and b = - 4

The solution for x in the equation 0.5x + 4 + 0.9x = x + 5 is 2.5.

Given that:

0.5x + 4 + 0.9x = x + 5

It is required to find the value of x.

In order to find the value of x, first operate the like terms together and then solve it to find the value of x.

Consider,

0.5x + 4 + 0.9x = x + 5

1.4x + 4 = x + 5

Subtract both sides by x.

0.4x + 4 = 5

Subtract both sides by 4.

0.4x = 5 - 4

0.4x = 1

Now, divide both sides by 0.4.

x = 1 / 0.4

Answer:

x = 2.8 hours

Explanation

Total distance = 350 km

Time period = 3 hrs

Hence we need to formulate an equation...,

Distance = Speed × Time

; Distance covered travelling at 120 = 120x Since the total time period was 3hrs...then the remaining time is (3 - x)

;Distance covered travelling at 60 = 60(3- x)

The equation is going to be...,

; 120x + 60(3 - x) = 350...since total distance is 350 km

; 120x + 180 - 60x = 350

; 60x = 170....divide both sides by 60

Hence..., x = 2.8 hours

This is an arithmetic sequence

The value of the 3rd term is 72

There are 4 terms in this sequence

The sequence starts at 60 and adds 6 repeatedly

Final answer:

To round 503.782 to the nearest tenth, the digit in the hundredths place is 8, which is greater than or equal to 5. Therefore, the rounded number is 503.8.

Explanation:

To adjust 503.782 to the closest 10th, we really want to take a gander at the digit in the hundredths place, which is the second digit after the decimal point. It is 7 in this instance.

Since 7 is more prominent than or equivalent to 5, we gather together the digit in the tenths place, which is the primary digit after the decimal point. For this situation, it is 8.

Therefore, 503.8 is obtained by rounding 503.782 to the nearest tenth.

To round 503.782 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is greater than or equal to 5, we round up. Therefore, the rounded number is 503.8.

Answer: 7/12

Step-by-step explanation:

Answer:

7/12

Step-by-step explanation:

The problem is asking us to find what fraction of students watch between 0 and 2 hours of TV a day:

The information we have is:

0 - 1 hours = 1/6

1 1/2 - 2 hours = 5/12

We only need this information because it is asking us for 0 to 2 hours.

Now we have to add the fraction of students that watch TV 0-1 hours and the fraction of students watch TV 1 1/2 - 2 hours:

1/6 + 5/12

To be able to solve this we have to have the same denominator and to do it we have to multiply the first fraction by 2:

(1/6) *2 = 2/12

Now we can add:

2/12 + 5/12 = 7/12

We add the numerators and the denominator stays the same.

The expression [tex]\(5x + 2x - 3\)[/tex] is a linear expression.

The expression [tex]\(5x + 2x - 3\)[/tex] represents a linear expression because it consists of terms involving only the variable \(x\) raised to the power of 1. In other words, each term is a linear term.

Linear expressions depict relationships that are straight lines when graphed on a Cartesian plane. In this case, \(5x\) and \(2x\) are both linear terms since they involve the variable \(x\) raised to the first power, while the constant term \(-3\) does not involve \(x\) at all.
