Which of the following ratios forms a proportion?

1 answer:

7 0

4/7 is a proportion to 16/28 because when you multiply both sides by 4 (4/4) you get 16 16/28. C & D are incorrect because 4/7 does not equal 16/35 or 20/25. A. & C are correct because you multiply (B.) or divide (A.) the numerator and denominator by (4/4) to get the right side of the equation.

So A & B are YES. C & D are NO

Given that CB is tangent to A at C, then the value of X is

Marat540 [252]

Well just use the formula a^2+b^2=c^2. C squared in this case will be 30, It does not matter whether 24 is a or b^2 since we are still adding them. Now your equation should look like this

a^2+24=30 then….

a^2=30-24

a^2=6

a=square root of 6

Therefore your radius is square root of 6 or x=square root of 6
