A worker is paid $18.50 per hour for the first 40 hours of work and time and a half for any overtime exceeding 40 hours per week
Lisa [10]

Answer:

The worker's pay is $795.50.

Step-by-step explanation:

The worker gets paid $18.50 for the first 40 hours of work. The worker works 46 hours. 18.50 • 40 = 740. He worked 6 hours overtime. $18.50 ÷ 2 = $9.25. $9.25 • 6 = $55.50.

$740 + $55.50= $795.50

How much p² – q² + 2pq is less than -2p² -2q² + 7pq +10 ?
ValentinkaMS [17]

Answer:   3p² + q² - 5pq - 10 < 0

<u>Step-by-step explanation:</u>

p² - q² + 2pq < -2p² - 2q² + 7pq + 10

since you didn't specify what to solve for, move everything from the right side to the left side of the inequality symbol using inverse operations.

(p² + 2p²) + (- q² + 2q²) + (2pq - 7pq) + (- 10) < 0

    3p²      +        q²        +      -5pq       +   -10  < 0

3p² + q² - 5pq - 10  < 0

The midpoints of an irregular quadrilateral ABCD are connected to form another quadrilateral inside ABCD. Complete the explanati
dem82 [27]

Answer:

Suppose: M, N, P, Q are the midpoints of AB, BC, CD, AD respectively

=> MNPQ is the quadrilateral inside ABCD

connect B to D, ΔABD has : M is the midpoint of AB

                                              Q is the midpoint of AD

=> MQ is the midpoint polygon of ΔABD

=> MQ // BD and MQ = 1/2.BD (1)

ΔBCD has: N is the midpoint of BC

                  P is the midpoint of DC

=> NP is the midpoint polygon of ΔBCD

=> NP // BD and NP = 1/2.BD    (2)

from (1) and (2) => MQ // NP ( //BD)

                            MQ = NP  (=1/2.BD)

=> MNPQ is a parallelogram.​

=>  the quadrilateral inside ABCD is a parallelogram.​
