Mathematics
1 answer:
Dmitrij [34]3 years ago
7 0

Answer:

\frac{1}{18}

Step-by-step explanation:

So say there are x yellow cubes.

Yellow = x

Blue = 3x

Green = 15x

It doesn't say red so I'm going to assume there are none.

\frac{x}{18x}=\frac{1}{18}

Y is directly proportional to x when y=30, x=6
rosijanka [135]

Answer:

a) y = 5x

b) y = 60

Step-by-step explanation:

Since, y is directly proportional to x when y=30, x=6

\therefore \:  y \:  \alpha \:  \: x \\ \therefore \:  y =  kx ...(1) \\ plug \: y = 30 \: and \: x = 6  \: in \: eq \: (1)\\ 30 = k \times 6 \\ k =  \frac{30}{6}  \\ k = 5 \\ plug \: k = 5 \: in \: (1) \\ y = 5x....(2) \: (required \: equation) \\ plug \: x = 12 \: in \: eq \: (2) \\ y = 5 \times 12 \\  \huge \red{ \boxed{y = 60}}

Are rhesw ratios equivalent 6:2 and 7:3
morpeh [17]

Answer:

No, they are not equivalent.

Step-by-step explanation:

There are two ways to check this.

1. You can multiply the means and extremes. If the ratios are equivalent, they products of the means and extremes will be equal.

Multiply the means (2 and 7) and multiply the extremes (6 and 3)

14 ≠ 18

2. You could also check these by dividing them.

6/2 = 7/3

3 ≠ 2.3

Since neither one of the checks are correct, 6:2 and 7:3 are not equivalent.


I really hope this helps =)
