draw a model to show 5.5 divided by 5?

We need to find which of the expressions does not have a two digit quotient.

The only expression which does not have a two digit quotient is [tex]\dfrac{915}{7}[/tex].

Let us check each expression

[tex]\dfrac{519}{6}[/tex]

Dividing each by three

[tex]\dfrac{173}{2}=86.5[/tex]

So, the quotient is betweem 86 and 87.

[tex]\dfrac{915}{7}[/tex]

[tex]7\times 130=910[/tex]

[tex]7\times 131=917[/tex]

So, the quotient will lie between 130 and 131.

[tex]\dfrac{439}{7}[/tex]

[tex]7\times 62=434[/tex]

[tex]7\times 63=441[/tex]

So, the quotient will lie between 62 and 63.

[tex]\dfrac{812}{9}[/tex]

[tex]9\times 90=810[/tex]

[tex]9\times 91=819[/tex]

So, the quotient will lie between 90 and 91.

Hence, the only expression which does not have a two digit quotient is [tex]\dfrac{915}{7}[/tex].

Answer:

3.71

Step-by-step explanation:

We are asked to divide 70.49 by 19.

We know that 19 times 3 is equal to 57 and 19 times 4 is 76, so 19 will go in 70 for 3 times and give a remainder of 13.

9)70.49( 3

  57

    13

Now, we will bring down 4. To do so we need to put a decimal in quotient as:

9)70.49( 3.71

  57

    134

   133

        19

       19

          0

Therefore, 70.49 divided by 19 is equal to 3.71.

Final answer:

The actual height of the Eiffel Tower is found by multiplying the height of the 1:800 scale model (40.5 cm) by the scale factor (800), resulting in an actual height of 32,400 centimeters.

Explanation:

To determine the actual height of the Eiffel Tower given a 1:800 scale model, you'll need to set up a proportion where the scale factor corresponds to the actual size and the model size. The model Eiffel Tower you've been given is 40.5 centimeters tall. Since the scale is 1:800, that means 1 centimeter on the model represents 800 centimeters in reality.

To find the actual height, you simply multiply the height of the model by the scale factor:

Actual height (x) = Model height × Scale factor

x = 40.5 cm × 800

x = 32,400 cm

Therefore, the actual height of the Eiffel Tower is 32,400 centimeters.

The unit rate for unloading trucks at the warehouse is 3 trucks per hour, which is calculated by dividing the total number of trucks (18) by the total number of hours (6).

To calculate the unit rate for unloading trucks at the warehouse where employees can unload 18 trucks in 6 hours, we simply divide the total number of trucks by the total hours. This gives us the unit rate of trucks per hour.

Unit rate calculation formula:

Unit Rate = Total Number of Trucks  Total Number of Hours

Unit Rate = 18 trucks  6 hours

Unit Rate = 3 trucks per hour

Therefore, the employees at the warehouse have a unit rate of unloading 3 trucks per hour.

To convert the mass of a 2-liter bottle of water from kilograms to grams, multiply 2 kg by 1000, resulting in 2000 grams.

A 2-liter bottle of water has a mass of 2 kilograms. To convert this mass into grams, we use the fact that 1 kilogram is equal to 1000 grams. Therefore, we perform a simple multiplication:

2 kilograms × 1000 grams/kilogram = 2000 grams.

So, the 2-liter bottle of water has a mass of 2000 grams.

To solve (22/7-2/3)÷2, find a common denominator and simplify within the parentheses, then divide the result by 2, giving the answer of approximately 1.2380952381.

To find the value of (22/7-2/3) divided by 2, you first need to calculate the expression within the parenthesis. You can start by finding a common denominator for 22/7 and 2/3, which is 21. Multiplying the numerator and denominator of 22/7 by 3 and 2/3 by 7 gives you

66/21 - 14/21 = 52/21

Now, you divide this result by 2, which is the same as multiplying by 1/2:

52/21 × 1/2 = 52/42 = 1.2380952381

If you use a calculator for the initial division, you have to ensure that you enter the calculation correctly to avoid errors. For example, using the expression 337/217, when calculated, gives you about 1.5529953917.

Proper use of parentheses is important to avoid mistakes like interpreting the expression as (5.7 x 2.8) / (3.1 x 4.2) instead of 5.7 x (2.8 / 3.1) x (1 / 4.2).

Both trains will leave the station together again in B. 36 minutes.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

We have been given that "A" train leaves a subway station every 12 minutes. An "E" train leaves every 9 minutes.

If both trains just left the station on parallel tracks, then both leave the station together again;

We will solving for the LCM (Least Common Multiple),

The LCM of 12 and 9

12 = 2 x 3 x 4 x 6 x 12

9 = 3x 1 x 9

The LCM of 12 and 9 is 36

Hence, Both trains will leave the station together again in B. 36 minutes.

The speed of the current is 5 mph and this can be determined by using the concept of upstream and downstream.

Given :

A motorboat takes 40 minutes to travel 20 miles downstream.

When the boat is going downstream current helps the boat and hinders when the boat is going up.

So, the boat downstream speed is given by:

[tex]\rm s = \dfrac{20}{40}=0.5\;miles \;per\;minute=30\;mph[/tex]

The speed of the boat going upstream is:

[tex]\rm s = \dfrac{20}{60}=\dfrac{1}{3}\;miles \;per\;minute = 20\;mph[/tex]

So, the speed of the current adds when the boat is going downstream and subtracted when the boat is going upstream.

Let the speed of the current be 'c' then:

s + c = 30

s = 30 - c     --- (1)

s - c = 20   --- (2)

Substitute the value of 's' inequation (2).

30 - c - c = 20

2c = 10

c = 5 mph

So, the speed of the current is 5 mph.

The amount of the tip of the total bill will be $10.53. Then the correct option is C.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Nina paid the bill for dinner with her family.

The total cost of the food was $65, and the restaurant added an 8 percent sales tax, $5.20, to the bill.

Then the amount of the bill will be

Bill = Cost of food + Sales tax

Bill = 65 + 5.2

Bill = $70.2

Nina wants to pay a 15 percent tip on the total bill including sales tax.

The amount of the tip of the total bill will be

Tip amount = 15% x $70.5

Tip amount = 0.15 x $70.5

Tip amount = $10.53

The amount of the tip of the total bill will be $10.53.

Then the correct option is C.

Final answer:

The long division of 1495 divided by 45 results in 33 with a remainder of 10. In the process of division, significant figures are considered, and our answer complies with this rule as both numbers have three significant figures.

Explanation:

To perform the long division of 1495÷45, we divide 1495 by 45 step by step.

The result of 1495÷45 is 33 with a remainder of 10. Therefore, 1495 divided by 45 is 33 remainder 10.

When considering significant figures in division, it's similar to the example stating that dividing 125 by 307 gives a long decimal, but we limit the precision to that of the least precise number. In this case, since 1495 and 45 both have three significant figures, the result of the division should also be limited to three significant figures, which our result of 33 (with a remainder) naturally complies with.
