This is fraction multiplication. We need to find 1/5 of 2/3 of the cake.
Multiply numerator by numerator, and denominator by denominator:
1/5 x 2/3 =
(1x2)/(5x3) =
2/15
The answer is A. 2/15

Determine whether y varies directly with x. If so, find the constant of variation and write the equation.

12345 [234]

ANSWER

$yes \: \: k = \frac{1}{3} \: \: \: y = \frac{1}{3} x$

EXPLANATION

The given line passes through the origin, hence it has equation of the form,

$y = kx$

Therefore y varies directly as x.

The line passes through the point (3,1)

This implies that,

$1= k(3)$

$k= \frac{1}{3}$

Hence the constant of variation is

$\frac{1}{3}$

The equation is

$y = \frac{1}{3} x$

At a putt putt course there are 50 yellow golf balls, 45 red golf balls, and 65 blue golf balls. What ratio compares the number

oksian1 [2.3K]

Blue balls : Total number.

Total number of balls = 50 + 45 + 65 = 160

Blue balls : Total number.

= 65: 160 Divide both by 5.
= 13 : 32

= 13/32. That is the ratio.
