Answer:

x=6

Step-by-step explanation:

1. (2.4x10^3)x(3x10^x)=7.2x10^9.    Divide both sides of the equation by

2.4 x 10^3)x3

which is 10^x = 10^6

2. 10^x = 10^6.  since the bases are the same, set the exponents equal

x = 6

so the answer is x = 6

Answer:

Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack

1.875/500=0.00375

each piece of paper is 0.00375

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= [tex]\frac{-6 + y}{2}[/tex]

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

Answer:

52.8

Step-by-step explanation:

cube volume formula: BH

                                   : 33 x 4.4 = 52.8

Marty read 4 times as many pages as Nelson and Jennifer COMBINED. Marty read 1,860 pages.

In total, after dividing Marty's total by 4, Jennifer and Nelson both read a total of 465 pages.

After subtracting Nelson's 240, Jennifer is then found to have read 225 pages.

B would be the best viable option, as it clearly shows that 240+?x4=1,860, which it does.

Hope this helped. Khan Academy is a great resource for any learner. :)

Answer:

4(240 + p) = 1860

225 pages.

Step-by-step explanation

4(240 + p) = 1860

960 + 4p = 1860

4p = 1860 - 960

4p = 900

p = 225.

The number of students walk to school is 378.

A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

For the given situation,

The total number of students = 540

Percentage of students walk to school = 70% = 0.70

Number of students walk to school = [tex]540(0.70)[/tex]

⇒ [tex]378[/tex]

Hence  we can conclude that the number of students walk to school is 378.

Answer:

Area of the rectangular pyramid is 82.8m²

Step-by-step explanation:

Number of rectangle = 1

Number of triangles = 4

Dimension of Rectangle = Length = 6 metres; Height = 2 metres

Dimension of 2 triangles: Base = 6 metres and Height = 8.8 metres

Dimension of other 2 triangles: Base = 2 metres and Height = 9 metres

Answer:

D- 52.5

Step-by-step explanation:

12ft + 3ft = 15ft

base= 15ft

height=7ft

area = 0.5 * b * h

area = 0.5 * 15 * 7

Answer:

52.5 ft^2

Step-by-step explanation:

7ft * 12ft = 84

84 / 2 = 42

7ft * 3ft = 21

21 = 2 = 10.5

42 + 10.5 = 52.5

To solve for a right sided triangle simply multiply the sides as if you were solving a square and then divide it by two. If you split these into two right sided triangles you can just solve each one and then add them

Answer:

957.25

Step-by-step explanation:

Answer:

"1 unit" is about 7.5 on the scale and the distance between Chicago and New York is about 10.8 on the scale.

Step-by-step explanation:

The scale factor on the map is 557.

When a shape is magnified and each side is multiplied by the same number, this is known as a scale factor. The scaling factor is this figure. Scale factors are used on maps to accurately depict distances between locations.

We have,

1 unit = 557 miles.

now, we have to find the scale factor,

i.e., the amount that must be multiplied by the map's unit of measurement to obtain the original distance between the two locations.

So, it means that the x unit = 557 x miles.

i.e. the scale factor = 557

Hence, The scale factor on the map is 557.

Answer:

Step-by-step explanation:

bias means you have an opinion on something and you make choices on it so a biased sample would not randomly chosen

The correct option is:

D.) It does not accurately represent the population.

In statistical analysis, sampling is the procedure by which researchers select a specific number of observations from a larger population. The sample strategy will depend on the sort of study being done, although it may involve systematic sampling or just plain random sampling.

It is a common statistics practice, when we want to study something from a population, we find a sample, which is a group of members of this population. The sample has to be representative of the population, that is, it has to involve all of its groups. If it does not involve all the groups, it is not an accurate representation of the population, and is called biased.

Hence, option C is correct.
