Answer:

constant of variation = \frac{1}{2}

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 2 when x = 4

k = \frac{y}{x} = \frac{2}{4} = \frac{1}{2}

Answer:

The constant of variation is 1/2.

Step-by-step explanation:

y = kx where k is the constant of variation.

So k = y/x = 2/4 = 1/2.

What value should go in the empty box to complete the calculation for finding the product of 62.834 × 0.45? A)2,213,360 B)2,313,
Aleonysh [2.5K]

Answer:

28.27530

Step-by-step explanation:

Given the expression 62.834 × 0.45, to solve this expression, first we need to convert it to fraction

62.834 = 62834/1000

0.45 = 45/100

Take the product if the resulting fraction:

62.834 × 0.45 = 62834/1000 × 45/100

= (62834×45)/1000×100

= 2,827,530/100,000

= 28.27530

Ok so this is so confusing The volume of water in a rectangular swimming pool can be modeled by the polynomial 2x3 _ 9x2 + 7x +
Alika [10]
The volume formula is V= l x L x H, l=width, L=Length, H= Depth, so 
2x3 _ 9x2 + 7x + 6 = l x L x (2x + 1), because H=(2x + 1), so 
l x L= (2x3 _ 9x2 + 7x + 6 )/ (2x + 1) = (2x3 _ 9x2 + 7x + 6 ) X [1/(2x + 1)]
case1: l= (2x3 _ 9x2 + 7x + 6 ) or L= 1/(2x + 1), case2: L= (2x3 _ 9x2 + 7x + 6 ) or l= 1/(2x + 1)
the why question:
perhaps there is similarity of value between volume and l, or volume and L

Solve the equation: 7(x + 8) = 49​
eduard

Answer:

-1

Step-by-step explanation:

1.)Reorder the terms:

7(8 + x) = 49

(8 * 7 + x * 7) = 49

(56 + 7x) = 49

2.)Solving

56 + 7x = 49

3.)Solving for variable 'x'.

4.)Move all terms containing x to the left, all other terms to the right.

5.)Add '-56' to each side of the equation.

56 + -56 + 7x = 49 + -56

6.)Combine like terms: 56 + -56 = 0

0 + 7x = 49 + -56

7x = 49 + -56

7.)Combine like terms: 49 + -56 = -7

7x = -7

8.)Divide each side by '7'.

x = -1

9.)Simplifying

x = -1

Hope this helps
