Answer: The ratios 3:9 and 2:6 are equivalent.

Step-by-step explanation:

This is because the unit ratio of 3:9 is 1:3.

To get this you can divide 3/3 and 9/3. This equals 1:3.

I know that 2:6 is equivalent to 3:9 because the unit ratio for 2:6 is also 1:3.

I can find this by dividing 2/2 and 6/2. This equals 1:3.

Therefore, <u>Yes</u> the ratios are equivalent.

What is 32 % of 50 ?
Aleksandr-060686 [28]

Answer:

The result=16

Step-by-step explanation:

The result of 32% of 50 can be expressed as;

R=P×O

where;

R=result

P=percentage

O=original value

In our case;

R=unknown

P=32 %

O=50

replacing;

R=32 % of 50

R=32%×50

R=(32/100)×50

R=0.32×5=16

The result=16

Math definitely isn't my greatest subject, if anyone knows how to do this and can explain it to me please help!
Law Incorporation [45]

Answer:

y-1 = 5/3(x-3)

Choice C

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

(3,1) (6,6)

m = (6-1)/(6-3)

m = (5/3)

the point slope form of a line is given by

y-y1 = m(x-x1)

You have point (3,1)

y-1 = 5/3(x-3)

Choice C

Ostrovityanka [42]

Answer: Your answer is 627


Step-by-step explanation: If you add 220 to 627, it becomes 847. You can find out by taking away 220 from 847 because the answer would be the same anyways.
