Response:

The measure of mHLK is "(204)°".

Step-by-step breakdown:

Given values include:

mJI = (3x+2)°

mHLK = (15x-36)°

and,

m∠HML = (8x-1)°

then,

What is mHLK?

Now,

Utilizing the chord-chord angle formula, we find

$mHMK=\frac{1}{2}(mJL+mHLK)$

Inserting the known values into the equation gives us

⇒ $(8x-1)=\frac{1}{2}(15x-36+3x+2)$

By carrying out cross-multiplication, we arrive at

⇒ $2(8x-1)=18x-34$

⇒ $16x-2=18x-34$

By subtracting "18x" from both sides, we obtain

⇒ $16x-2-18x=18x-34-18x$

⇒ $-2x-2=-34$

Upon adding "2" to both sides, we end up with

⇒ $-2x=-34+2$

⇒ $-2x=-32$

⇒ $x=\frac{32}{2}$

⇒ $x=16$

By substituting the value of "x" into mHLK = (15x-36)°, we calculate

⇒ (15x-36)° = (15×16-36)°

⇒ = (240-36)°

⇒ = (204)°

Thus, mHLK = (204)°

A dental laboratory technician earns $14 per hour when she work days and $18 per hour when she works nights. One month she works

Inessa [12570]

Answer:

Her accumulated earnings for the month total $2208

Step-by-step explanation:

A dental lab technician receives $14 hourly for day shifts and $18 hourly for night shifts.

During one month:

She completed six 4-hour day shifts

Thus, total hours worked = $6 \times 4 = 24 hours$

Three 8-hour day shifts = $3 \times 8 = 24 hours$

Three 10-hour day shifts = $3 \times 10 = 30 hours$

Total day hours = 24+24+30=78 hours

Hourly rate for daytime work = $14

Cost for 78 day hours = $14 \times 78 =1092$

Five 6-hour night shifts= $5 \times 6 = 30 hours$

Four 8-hour night shifts = $4 \times 8 = 32 hours$

Total night hours = 30+32=62 hours

Hourly rate for nighttime work = $18

Cost of 62 night hours = $62 \times 18=1116$

Thus, total monthly earnings = $1092+$1116 = $2208

Consequently, her total pay for the month amounts to $2208

Llen missed 5 targets, which is due to -50 divided by -10 equaling 5. I hope this clarifies! <3

Answer:

96 cubic feet

Step-by-step explanation:

The volume calculation for the dimensions of 16 ft by 18 ft by 1/3 ft is as follows:

V = LWH

V = (16 ft)(18 ft)(1/3 ft) = 96 ft³

Thus, 96 cubic feet of concrete will be required.
