Answer:

Formula for gravitational force    F = G M1 * M2 / R^2  where G is the gravitational constant

F2 / F1 = (R1 / R2)^2 = 1/2         where F2 is the required force

R2 = (2)^1/2  R1     distance for R2 to be 1/2 force at R1

Since force is proportional to the square of the distance of separation, increasing the distance of separation by 2^2 will halve the force

Evaluate when x=5; X + 3*<br> 02
BaLLatris [955]

Answer:

The answer is 11

Step-by-step explanation:

The answer is 11 becasue if you substitute X for 5 the expression becomes 5+3*2 and 3*2 is 6 and 5+6 equals 11. if the two represents square (3 to the power of 2) the answer is 14 becasue 3 to the power of 2 is 9 and five plus nine is 14.

The area of a rectangular fence is 500 square feet. If the width of the
lions [1.4K]

Answer

Here the area and the width of the rectangular fence are given. We have to find length of the fence.

( diagram )

The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.

Given that area is 500 square feet and width is 20 feet.

Substituting values in formula,

⇒500=l×20

⇒20/500

​

= 20/1×20

​

    [ Dividing both sides by 20 ]

⇒l=25  feet

∴ length of rectangular fence is 25 feet.

Hence, the answer is 25.

(6x+4y=43)( 2x-3y=23)
SashulF [63]

Answer:

(8.5, - 2 )

Step-by-step explanation:

Given the 2 equations

6x + 4y = 43 → (1)

2x - 3y = 23 → (2)

Multiplying (2) by - 3 and adding to (1) will eliminate the term in x

- 6x + 9y = - 69 → (3)

Add (1) and (3) term by term to eliminate x, that is

13y = - 26 ( divide both sides by 13 )

y = - 2

Substitute y = - 2 in either of the 2 equations and solve for x

Substituting into (1)

6x + 4(- 2) = 43

6x - 8 = 43 ( add 8 to both sides )

6x = 51 ( divide both sides by 6 )

x = 8.5

Solution is (8.5, - 2 )

Artemon [7]
C.) 68
Why?
a triangle has 180 degrees. 
The tics denote the sides being equal, which means the opposite angles are equal, too. To get the remaining subtract it from 180... 180- 2(56) =68 degrees
