there are 239 people in the first 6 rows of a movie theater if the same number of people are in the next 6 rows about how many people are in the first 12 rows ?

Answers

6+6=12 so if there is 239 people in the first 6 rows, the other six rows also has the same amount of people. So you add 239+239 and you got your answer, 478 people are in the first 12 rows

In the first twelve-row, the total number of people is 478 and this can be determined by using the arithmetic operations.

Given :

The total number of people in the first six rows is 239.

The same number of people are in the next 6 rows.

Arithmetic operations can be use to determine the total number of people in the first twelve rows.

Given that there are 239 people in the first six rows and the same number of people in the next six rows. Therefore, in the next six-row, the total number of people are 239 as well.

Therefore, in the first twelve-row the total number of people = 239 + 239

= 478.

Each of the 18 tires of a fully loaded semi truck is bearing approximately 3,300 pounds. The unloaded truck and trailer, with the driver aboard weighs 30,000 pounds. The truck holds 26 pallets of cargo when it is fully loaded. What is the approximate average weight of one pallet of cargo? A. 1,131 lbs
B. 1,280 lbs
C. 1,633 lbs
D. 1,665 lbs

Answers

Process of elimination is helpful here. 

Starting with A, if every pallet weighs approximately 1,131 pounds and there are 26 pallets, then that's 29,406 total pounds of additional weight. Add that additional weight to the 30,000 of the truck and trailer and you have 59,406 total pounds. If you divide that number by 18, you get the total number of pounds that each tire is supporting. 59,406 divided by 18 is 3300, so that seems to be the answer. 

Answer:  A. 1,131 lbs

Step-by-step explanation:

Given: the weight of each tire of a fully loaded semi truck  = 3,300 lbs

Then the weight of 18 tires of a fully loaded semi truck = [tex]18\times 3300=59400\ lbs[/tex]

Also, the unloaded truck and trailer, with the driver aboard weighs 30,000 pounds.

Therefore, the weight of pallets = [tex]59400-30000=29400\ lbs[/tex]

Hence, the weight  of 26 pallets of cargo when it is fully loaded= 29400 lbs

Now, the weight of each pallet= [tex]\frac{29400}{29}=1130.76923077\approx1131\ lbs[/tex]

∴ The approximate average weight of one pallet of cargo= 1131 lbs

what is 2.25 as a fraction

Answers

The answer is 2 1/4 because 0.25 is equal to 1/4. So 1/4 plus 2 is 2 1/4

the first thing to do here is convert it to a mixed number.

.25 should be a somewhat familiar decimal. it's created by the fraction (1/4), so instead of 2.25, you could write this as 2 1/4 (two and one-fourth).

now that you have 2 1/4, convert it to an improper fraction. remember, multiply the bottom of your fraction with the big number out front, then add to the top of your fraction. set it over your denominator.

2 1/4  ... 4*2 is 8, 8 + 1 is 9, and your resulting fraction is (9/4).

Ling is training for a marathon by jogging 6.3 kilometers every other day. How many meters does she jog every other day

Answers

It simply asks you to convert 6.3 km to meters.
There are 1000 km in 1 meter.
So for 6.3 km, there are 6.3km * 1000 = 6300 m.

You can also use the factor label method.
[tex] \frac{6.3km}{1m} * \frac{1000m}{1km} =6300m[/tex]
Final answer:

Ling jogs 6300 meters every other day while training for a marathon. The conversion from kilometers to meters was done by multiplying the kilometer value (6.3) by 1000.

Explanation:

To answer the question of how many meters Ling jogs every other day, we need to convert the distance from kilometers to meters. In the metric system, 1 kilometer is equivalent to 1000 meters. Therefore, if Ling jogs 6.3 kilometers every other day, we multiply 6.3 by 1000 to obtain the equivalent distance in meters.

Calculation: 6.3 kilometers * 1000 = 6300 meters.

So, Ling jogs 6300 meters every other day while training for the marathon.

Draw and label a rectangle prism that has a surface area of 158 square yards

Answers

A rectangular prism with dimensions [tex]\(8 \times 5 \times 3\)[/tex] yards has a surface area of 158 square yards, verified by substituting into the surface area formula.

To draw and label a rectangular prism with a surface area of 158 square yards, we first need to understand the surface area formula for a rectangular prism.

The surface area \(A\) of a rectangular prism can be found using the formula:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

Where[tex]\(l\), \(w\), and \(h\)[/tex] are the length, width, and height of the rectangular prism, respectively.

Given the surface area[tex]\(A = 158\)[/tex] square yards, we can now find different combinations of [tex]\(l\), \(w\), and \(h\)[/tex] that satisfy this equation.

One possible combination is [tex]\(l = 8\), \(w = 5\), and \(h = 3\).[/tex] Let's verify this:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

[tex]\[ = 2(8 \times 5) + 2(8 \times 3) + 2(5 \times 3) \][/tex]

[tex]\[ = 2(40) + 2(24) + 2(15) \][/tex]

[tex]\[ = 80 + 48 + 30 \][/tex]

[tex]\[ = 158 \text{ square yards} \][/tex]

Therefore, a rectangular prism with dimensions [tex]\(8 \times 5 \times 3\)[/tex]yards will have a surface area of 158 square yards.

Now, to draw and label the rectangular prism:

- Draw a rectangular prism with dimensions [tex]\(8 \times 5 \times 3\)[/tex] yards.

- Label the length[tex](\(l\)),[/tex] width [tex](\(w\)),[/tex] and height[tex](\(h\))[/tex] accordingly.

The question probable may be:

Each Day Marvin exercises for 48 minutes.How many days will it take him to exercise for 576 minutes?

Answers

You take the total number of minutes he wants to exercise divided by how much he exercises each day to find how many days it will take

576 / 48 = 12

It will Marvin 12 days to exercise 576 minutes if he exercises 48 minutes every day
Final answer:

By dividing the total desired exercise minutes (576) by the daily exercise duration (48 minutes), we find that Marvin will need 12 days to reach 576 minutes of exercise.

Explanation:

To calculate how many days it will take Marvin to exercise for a total of 576 minutes, given that he exercises for 48 minutes each day, we divide the total minutes he wants to achieve by the number of minutes he exercises daily.

Total minutes desired: 576 minutes

Daily exercise duration: 48 minutes

To determine the number of days required, we perform the following calculation:

Divide 576 by 48.The result is the number of days Marvin needs to exercise to reach 576 minutes.

576 minutes ÷ 48 minutes/day = 12 days

Therefore, it will take Marvin 12 days of exercising for 48 minutes each day to accumulate 576 minutes of exercise.
