- Mars to Earth:
35,000,000 miles = 3.5 * 10^7 miles
- Pluto to Earth:
4,670,000,000 miles = 4.67 * 10^9 miles
- The ratio of the distances:
4.67 * 10^9 : 3.5 * 10^7 = 133.43 : 1

we have that

Mars is 35 million miles from the Earth.

Pluto is 4.67 billion miles from the Earth.

we know that

1 billion=1,000,000,000=1*10^{9}

Part 1) Express the distance from Mars to Earth in scientific notation

35\  million\ miles=35,000,000\  miles=3.5*10^{7}\  miles

therefore

the answer part 1) is

3.5*10^{7}\  miles

Part 2) Express the distance from Pluto to Earth in scientific notation

4.67\ billion\  miles=4,670,000,000\ miles=4.67*10^{9}\ miles

therefore

the answer Part 2) is

4.67*10^{9}\ miles

Part 3) Calculate the ratio of the distance from Pluto to Earth to the distance from Mars to Earth. Use scientific notation to calculate the ratio and to express your answer

ratio=\frac{4.67*10^{9}}{3.5*10^{7}}  \\  \\ ratio=\frac{4.67*10^{2}}{3.5}}\\ \\ ratio=\frac{467}{3.5} \\ \\ ratio=133.43

ratio=1.3343*10^{2}

therefore

the answer Part 3) is

1.3343*10^{2}

sergejj [24]

Answer:

26

Step-by-step explanation:

Let x be the first even integer

x+2 is the second even integer

x+4  is the third even integer

The sum of three consecutive even integers is 84

x+ (x+2) + (x+4) =84

Combine like terms

3x +6 = 84

Subtract 6 from each side

3x+6-6 =84-6

3x =78

Divide each side by 3

3x/3 = 78/3

x =26

The three integers are 26, 28,30

The smallest is 26

Santos went on a bike ride of 90 miles. He realized that if he had gone 24 mph faster, he would have
Gnoma [55]
<h3>Answer:  6 mph</h3>

========================================

Explanation:

distance = rate*time

90 = r*t

where r is the slower speed and t is the time it takes when going that slower speed.

If r is bumped up 24 mph faster, to r+24, then Santos takes t-12 hours to get there. The second equation is

90 = (r+24)(t-12)

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

We can solve the first equation for r to get r = 90/t

Then plug this into the second equation and do a bit of algebra

90 = (r+24)(t-12)

90 = (90/t+24)*(t-12)

90 = 90 - 1080/t + 24t - 288

90t = 90t - 1080 + 24t^2 - 288t

0 = 90t - 1080 + 24t^2 - 288t-90t

0 = 24t^2 - 288t - 1080

24t^2 - 288t - 1080 = 0

If you apply the quadratic formula, then you should get the two solutions t = -3 and t = 15. Due to time constraints, I'll skip these steps.

We'll ignore the negative t value. It makes no sense to have a negative time.

So we focus on t = 15 as the only solution.

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

If t = 15, then,

r = 90/t

r = 90/15

r = 6

Santos rode his bike at <u>6 mph</u> at first. Going this speed means he takes 15 hours.

If he rode 24 mph faster, at 6+24 = 30 mph, then he would ride for 15-12 = 3 hours instead. Note that 90/30 = 3.

ahrayia [7]

Answer:

$6

Step-by-step explanation:

In order to find the amount of the tip that T.J. and Lindsey will leave for their waiter, you have to multiply the lunch cost for the percentage they want to leave as a tip for their waiter:

Lunch cost=$30

Percentage they want to leave as a tip= 20%

$30*20%=$6

According to this, the answer is that the amount of the tip is $6.
