- 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}

5x-8y=40 what is the x intercept
Artist 52 [7]
Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:

5x - 8(0) = 40.

As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).

A bicycle that usually sells for 230 is on sale for 15% off. Find the sale price
SSSSS [86.1K]

Answer: $172.50

Step-by-step explanation: Method 1:

The original price of the item is $230.

The discount is 25%.

Let's find 25% of $230.

25% of $230 = 0.25 * $230 = $57.50

The discount amount is $57.50.

Now we subtract the amount of the discount from the original cost.

Sale price = $230 - $57.50 = $172.50

Method 2.

The original price is $230.

That means that $230 is 100% of the price since 100% of a thing means the entire thing.

Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%.

The sale price is 75% of the original price.

Now we find 75% of $230.

75% of $230 = 0.75 * $230 = $172.50

Elanso [62]
D. $ 3x30

Since $2.87 round to $3 and 27 rounds to 30 you would multiply the cost of each bag ($3) by the amount of people (30) meaning your estimate would be 30x3 which equals $90
