The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle

to reach Saturn from Earth. (Assume both planets are aligned with the sun and are on the same side of the sun.)

Answer:

t = 42857.14 h

Step-by-step explanation:

Given that,

The speed of space shuttle, v = 28000 km/h

We know that, the distance between the Saturn and the Earth is 1,200,000,000 km.

Let t be the time.

As we know, speed = distance/time

So,

t=\dfrac{d}{v}\\\\t=\dfrac{1,200,000,000}{28000}\\\\t=42857.14\ h

So, the required time is equal to 42857.14 hours.

The population of California is approximately 38,040,000. The population of Texas is about 2.606 × 107. What is the approximate
liubo4ka [24]

Answer:

The total population of these two states is:

3.804\times \:\:10^7+2.606\times \:\:10^7\:=10^7\times \:\:6.41

Therefore, option C is correct.

Step-by-step explanation:

  • The population of California is approximately 38,040,000.
  • The population of Texas is about 2.606 × 10⁷.

Writing the population of California i.e.38,040,000  in scientific notation by moving the decimal point 7 places to the left and dropping the 0's on the right  side as they're after the decimal point now.

i.e.

38,040,000 = 3.804 x 10⁷

So adding 3.804 x 10⁷ and 2.606 × 10⁷

i.e.

3.804\times \:10^7+2.606\times \:10^7

\mathrm{Add\:similar\:elements:}\:10^7\times \:3.804+10^7\times \:2.606=10^7\times \:6.41

Thus, the total population of these two states is:

3.804\times \:\:10^7+2.606\times \:\:10^7\:=10^7\times \:\:6.41

Therefore, option C is correct.

D= number of dollars

<u>Unit rate 4:</u>

The table

d      n

4       1

8       2

16      4

<u>Unit rate 1/4:</u>

Table

d      n

1       4

4       16

16      64

and

The equation n=4d

<u>Unit rate 16:</u>

Equation:

d = 16n

Step-by-step explanation:

The unit in the unit rate is dollars per unit ounces which means that the unit rate calculated by

Unit\ rate = \frac{dollars}{ounces}

So,

The first option is the equation:

d = 16n\\\frac{d}{n} = 16

The unit rate is 16 dollars per ounce

The second option is the table:

d      n

1       4

4       16

16      64

We can take any pair of values of d and n from the table to calculate the unit rate

So taking

d = 1

n=4

Unit\ rate = \frac{d}{n}\\= \frac{1}{4}

The unit rate for table is: 1/4 dollars per ounces

Third option is the equation:

n = 4d

n = 4d

dividing both sides by n

\frac{n}{n} = \frac{4d}{n}\\1 = \frac{4d}{n}

dividing both sides by 4

\frac{1}{4} = \frac{4d}{4n}\\\frac{d}{n} = \frac{1}{4}

the unit rate is 1/4 dollars per ounce

Fourth option is the table:

d      n

4       1

8       2

16      4

We will take any pair of d and n to find the unit rate

So,

Taking

d = 4

n =1

Unit\ rate = \frac{d}{n} \\= \frac{4}{1}\\=4

The unit rate is 4 dollars per unit ounce.
