Clint earns $25.50 per hour as a mechanic. He is paid time-and-a-half for working more than 8 hours per day. Yesterday, he worke
777dan777 [17]

Answer:

439.87

Step-by-step explanation:

Time and a half is the original hourly rate plus half of that. Being that Clint's hourly rate is $25.50, you will add $12.75 to that because that is half of 25.50. So for the 11.5 hours worked, Clint's gross pay comes out to be $439.87. First figure out time and a half as shown above. Next, multiply time and a half by the number of hours worked on said day. You then have the answer for what is Clint's gross pay.

Will give brainliest plzzzzz.Which statement justifies why ∠EBC measures 90°? Given: angles ABD and DBC are complementary Point
Anettt [7]

Answer:

he sum of the measures of two complementary angles is 90 degrees

Step-by-step explanation:

we know that

If two angles are complementary, then their sum is equal to 90 degrees

In this problem we have that

m∠ABD and m∠DBC are complementary

so

m∠ABD + m∠DBC=90° -----> by complementary angles

and

(m∠ABD + m∠DBC)+m∠EBC=180° -----> by a linear pair

Find the measure of angle EBC

substitute the given values

(90°)+m∠EBC=180°

∠EBC=180°-90°=90°
