Answer:

D: y = 5x

Step-by-step explanation:

According to Google, a proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if: y=kx. for some constant k , called the constant of proportionality. So the only one in that form would be the y = kx.

The constant k = 5

How many millimeters are equal to 4 liters

stealth61 [152]

Answer:

there is no relation between millimeters and liters

4000 milliliters = 4 liters

Step-by-step explanation:

"milli-" is a prefix meaning 1/1000. So 1 milliliter = (1/1000) liter. Thus it takes 1000 milliliters to make 1 liters, hence 4000 milliliters to make 4 liters.

_____

A meter, and a millimeter, is a measure of distance. A liter, and a milliliter, is a measure of volume. There is no sensible conversion between linear (one-dimensional) distance and 3-dimensional volume.

Equation- s=db-6, solve for d

Liono4ka [1.6K]

Answer:

$d \: = \frac{s + 6}{b}$

Step-by-step explanation:

$s = db - 6$

Isolate d

$s + 6 = db$

Divide both sides of the equation by b

$\frac{s + 6}{b} = \frac{db}{b}$

Simplify

$\frac{s + 6}{b} = d \\ d = \frac{s + 6}{b}$

We can see here that there are 2 triangular bases on the prism.

To calculate the area of a triangle, we multiply the base and the height and then divide by 2.

A = 8 x 6 /2

A = 48/2

A = 24

Hope it helps!

AB = 24
BC = 45
AC = 51

cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
