Answer:

3 1\2

Step-by-step explanation:

it's simple who plays C- a equals 6 2 C / 2 equals 19/2 which equals c which equals 9 1/2 next add 9 and 1/2 plus B&D which equals 6 + 8 which equals to 9 1/2 do 9 / 1/2 + B which equals 14 + that b equals 14 -9 1/2 which equals to be equal in 4 and 1/2 . 8 + 4 and 1/2 equals 8 which means a equals 8 - 4 and 1/2 which equals 3 1/2 so because A&D are the same which is 3 1/2 your answer is 3 and 1/2

Svetlanka [38]

On average, Mercury is about 57,000 ,000 km from the sun, whereas Neptune is about 4.5 x 10^9 km from the sun. What is the difference between Mercury's and Neptune's distance from the sun?

<h3>Answer:</h3>

Difference between Mercury's and Neptune's distance from the sun is $4.443 \times 10^9 \text{ km }$

<h3>Solution:</h3>

Given that,

Distance of mercury from sun = 57, 000, 000 km

Distance of Neptune from sun = $4.5 \times 10^9 \text{ km }$

To find: Difference between Mercury's and Neptune's distance from the sun

Let us convert distance of mercury from sun to scientific notation

Scientific notation is used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits

Steps to remember:

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b

$57, 000, 000 = 5.7 \times 10^7$

Therefore,

Distance of mercury from sun = $5.7 \times 10^7 \text{ km }$

Calculating difference between Mercury's and Neptune's distance from the sun:

difference = Distance of Neptune from sun - Distance of mercury from sun

$\text{ difference } = (4.5 \times 10^9) - (5.7 \times 10^7)$

Let us make both powers same

$\text{ difference } = (4.5 \times 10^9) - (0.057 \times 10^9)$

Taking 10 power 9 common we get,

$\text{ difference } = 10^9(4.5-0.057)\\\\\text{ difference } = 10^9 \times (4.443)\\\\\text{ difference } = 4.443 \times 10^9$

Thus difference between Mercury's and Neptune's distance from the sun is $4.443 \times 10^9 \text{ km }$

SOMEBODY HELP THAT DOES NOT MIND HELPING WITH MORE !!

ch4aika [34]

The answer would be A) rational.

The rational number is number that can be represented as a ratio of "a/b" where a and b is an integer. When you multiply two rational number of a/b and c/d, the result would be: a/b * c/d= ac/ bd
Since a and c is an integer, the product of ac would be integer too. The same thing applies to bd.
Since ac and bd is an integer, then ac/bd would be a rational number

Please help and please provide the steps to solve this! Thanks

otez555 [7]

slope = m = (y2 - y1)/(x2 - x1)

(y2 - y1)/(x2 - x1) = m

(-1 - 1)/(-1 - x) = 2/7

-2/(-1 - x) = 2/7

2/(x + 1) = 2/7

1/(x + 1) = 1/7

x + 1 = 7

x = 6

Answer: x = 6

ollegr [7]

The Pythagorean Theorem states that a² + b² = c², c being the hypotenuse.

Substitute known values into the equation.

7² + 2² = c²
49 + 4 = c²
c² = 53
c = √53
c = 7.28010989

Answer: The hypotenuse's length is 7.3 feet.
