The speed thing above the chart, ya pretend that is not there

For this case we have:

a)

to convert as a percentage we have:

* 100% = 10%

b)

, if we multiply the numerator and denominator by 25 we have:

c)

Now we must write a fraction that represents 50%.

We have. If we multiply the numerator and denominator by 50 we have:

10%

Step-by-step explanation:

To find "a" you can multiply by 100, then this is:

To find "b", you can multiply the numerator and the denominator of the fraction by 25, getting:

To find "c", you can reduce the fraction . Then you get that this is:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
