The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun is 1.1 ⋅ 108 kilometers. About how many more kilometers is the distance of Venus from the Sun than the distance of Mercury from the Sun?

Answers

Answer 1

Answer:

Answer: $5.2\cdot10^7\ km$

Step-by-step explanation:

Given: The approx distance of planet Mercury from the Sun $=5.8\cdot10^7\ km=58,000,000\ km$

The distance of planet Venus from the Sun $=1.1\cdot10^8\ km=110,000,000\ km$

We can see the

The difference distance of planet Venus from the Sun is more than the distance of planet Mercury from the Sun.

The difference between the distance = $110,000,000-58,000,000=52,000,000=5.2\cdot10^7\ km$

Hence, the distance of Venus from the Sun is $5.2\cdot10^7\ km$ more than the distance of Mercury from the Sun.

Answer 2

Answer: mercury : 5.8 • 107 = 620.6
Venus : 1.1 • 108 =118.8

620.6 - 118.8 = 501.8

so Venus is about 501.8 kilometers from then sun then mercury

Answers

No because if you divide 1 by 8 you get .125 and if you divide 1 by 3 you get .33 repeating and . 33 repeating is a larger decimal and that means 1/3 is a larger fraction

First you have to find a common multiple... in this case, 24 then you have to multiply the numerator by the same number that made the denominator 24...which is 3 and 8 so the answer would be....No

Answer:

Step-by-step explanation:

We can use the triangle angle bisector theorem

x+8 2x-5

--------- = ------------

10 14

Using cross products

14(x+8) = 10 (2x-5)

Distribute

14x +112 = 20x -50

Subtract 14x from each side

14x-14x +112 = 20x-14x -50

112 = 6x-50

Add 50 to each side

112+50 = 6x-50+50

162 = 6x

Divide by 6

162/6 = 6x/6

Answer:

x > 6

Step-by-step explanation:

-5 > 19 - 3x + (-6)

Combine like terms.

-5 > 13 - 3x

Subtract 13 from both sides.

-18 > -3x

Divide both sides by -3.

6 < x

Flip this around. x > 6

Step-by-step explanation:

A 4-ounce cup of coffee costs $8.00. How much would a 3-ounce cup of cofee codt?

Answers

To solve this, we must first find out the cost-per-ounce of a cup of coffee. Assuming that the rates are flat, then we can just divide the 8-dollar-cost by the 4-ounce cup that it buys.

8 / 4 = 2

The cost-per-ounce of a cup of coffee is $2.
Now, we just have to multiply the cost-per-ounce by the amount of coffee we want to find out the cost of.

2 * 3 = 6

With all else constant, a 3-ounce cup of coffee would cost $6.
