The amount of a persons paycheck p varies directly with the numbers of hours worked t. for 25 hours of work, the paycheck is $31
kotegsom [21]

Answer:

p = t * 12.5

Step-by-step explanation:

To find the relationship between hours of work and the pay, I divided the total paycheck given by the 25 hours of work, which got me what a 25th of that paycheck would be, which represents what you would earn in an hour with a flat rate.

312.50 / 25 = 12.5

Check:

12.5 * 25 (hours of work) = 312.50 (Given total paycheck)

That's how we know the pay per hour, which is the relationship between t and p.

Write each trigonometric ratio as a fraction in simplest form. show all supporting work
Nesterboy [21]

Answer: \frac{x}{20}

Step-by-step explanation:

Sine uses the ratio,  \frac{opposite}{hypotenuse} so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

sinA=\frac{x}{20}

You can't reduce this any further because there is an unknown variable.
