Answer:

EcD= 52 DCB=128

Step-by-step explanation:

First, let's find out what x equals and what (x+11) equals

(x+11)+(3x+5)=180\\4x+16=180\\4x=164\\x=41

And therefore...

x+11=52

Now angle ecd is a vertical angle we just found.

So angle ECD= 52 degrees

And agles ECD and DCD and supplimntary

52+?=180\\DCB=128

Sara worked 45 hours one week, of which 5 hours were overtime. She earned $10.48 per hour and gets paid time and a half for over
marissa [1.9K]

Answer:

$497.80

Step-by-step explanation:

First, you want to find half of 10.48. This should be 5.24.

So, add 10.48 and 5.24. This gives you 15.72.

Now, you want to multiply that by 5, since 5 hours were overtime.

This gives you 78.60.

Lastly, you want to multiply 10.48 by 40.

This gives you 419.20

Now, add 78.60 and 419.20 together, giving you your answer of $497.80

Sara got $497.80 for the week.

➷The answer is 18 hours.

Explanation: If you look carefully, you can see that the answer is the second condition as well. If one pipe did half, then the other pipe took over and that took 18 hours, that means that it equals one pipe filling the pool continuously by itself. :)
