Answer:

x = 42

Step-by-step explanation:

$\frac{2}{4} x - 3 = 4 + \frac{1}{3} x \\ \\ \implies \: \frac{1}{2} x - \frac{1}{3} x = 4 + 3 \\ \\ \implies \: \frac{3 - 2}{6} x = 7 \\ \\ \implies \: \frac{1}{6} x = 7 \\ \\ \implies \: x = 7 \times 6 \\ \\ \implies \: x = 42$

Answer:

10.5in

Step-by-step explanation:

DC=16in is similar to OP=12in.

So the ratio is 12/16=3/4.

Now AD=14in.

MP=AD×ratio=14×3/4=21/2=10.5in

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 $4.443 \times 10^9 \text{ km }$

What is the surface area of a cube that is 4 cm on each edge?

icang [17]

Answer:

96 units squared

Step-by-step explanation:

The surface area of a cube can be written as 6 * (s^2)

s is the side length.

4^2 = 16.

6 * 16 = 96.

This is because the area of a cube is s^2.

There are 6 sides to a cube, so we multiply them.
