This is a simple right triangle problem.
a^2 + b^2 = c^2

the hypotenuse (or c) is 9 +x
and a is x
And b is 15

So so we sub in the values
x^2 + (15)^2 = (9+x)^2

x^2 + 225 = x^2 + 18x + 81
144 = 18x
8 = x

Solve the proportion. Please explain how you managed to get the answer! I don't know how to get there!
belka [17]
All you need to do is cross multiply and then solve for x
\frac{8}{x+9} =  \frac{2}{x-3}  \\ 8(x-3)=2(x+9) \\ 8x-24=2x+18 \\ 6x-24=18 \\ 6x=42 \\ x=7

Vladimir [108]

Answer: It is not.

Step-by-step explanation:

The salaries paid to the various departments of a company are usually different as some departments get paid more than others. For instance, in a manufacturing company, the R&D department would on average, get paid more than members of the Cleaning department.

Asking members of only one department therefore, about their pay satisfaction would not bring about a reasonable result because it would not be indicative of the thoughts of members of the other departments who are not being paid the same.

Cheryl workers 43.75 hours this week at a rate of $8.15 per hour. She gets paid overtime(time and a half) for any hours over 40.
mote1985 [20]

Answer:

371.84$

Step-by-step explanation:

Normal hourly rate = $8.15 per hour

Overtime rate = time and a half = 1.5 x normal hourly rate = 1.5 x $8.15 = $12.23 per hour

Given that she works 43.75 hours,

= 40 normal hours + 3.75 Overtime

Total Pay,

= (40 x normal rate) + (3.75 x Overtime rate)

= (40 x $8.15) + (3.75 x $12.23)

= $326 + $45.84

= $371.84
