Answer: The approximate length of PQ is 10.8 unit.

Step-by-step explanation:

Here the coordinates of point P are (-3,7) and the coordinates of Q are (6,1)

Thus, by the distance formula,

The distance between the points P and Q is,

$PQ = \sqrt{(6-(-3))^2+(1-7)^2}$

$=\sqrt{(6+3)^2+(-6)^2$

$=\sqrt{9^2+ 36}$

$=\sqrt{81+36}=\sqrt{117}=10.8166538264\approx 10.8$

Thus, the approximate length of PQ is 10.8 unit.

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary

The description of the angles in the quadrilaterals are:

b. m∠M = 55°, m∠J = 48°, and m∠L = 132°
d. m∠L = 40°, m∠M = 60°, and m∠K = 120°
e. m∠K = 72°, m∠L = 44°, and m∠M = 108°
f. m∠J = 105°, m∠K = 65°, and m∠L = 75°

<h3>How to describe the angles</h3>

The quadrilateral is given as: JKLM

The opposite angles are:

Angles J and L
Angles K and M

The opposite angles are supplementary

So, we have:

$J + L = 180$

$K + M = 180$

Next, we test the options

Option (a)

$J + L = 180$

$125 + 35 = 160$

This is not true

Option (b)

$J + L = 180$

$48 + 132 =180$

This is true

Option (c)

$K + M = 180$

$12 + 78 = 180$

This is not true

Option (d)

$K + M = 180$

$120 + 60 = 180$

This is true

Option (e)

$K + M = 180$

$72 + 108= 180$

This is true

Option (f)

$J + L = 180$

$105 + 75 = 180$

This true

Hence, the description of the angles in the quadrilaterals are (b), (d), (e) and (f)

A mowing company charges $840 plus $17 per hour. Another moving company charges $760 plus $22 per hour. How long is a job that c

Korvikt [17]

Answer: 16 hours

Step-by-step explanation:

The two equations are:

840 + 17x

and

760 + 22x

with x being the amount of hours

840 + 17x = 760 + 22x

-760

80 + 17x = 22x

-17x

80 = 5x

16 = x

840 + 17(16) = 1,112

760 + 22(16) = 1,112
