What is m QW I’m super confused!??

Given:

QT and RW are diameters in circle P.

To find:

The measure of arc QW.

Solution:

RW is a diameter.

The sum of the angles in the diameter is 180°.

m∠RPQ + m∠QPW = 180°

40° + m∠QPW = 180°

Subtract 40° from both sides.

40° + m∠QPW - 40° = 180° - 40°

m∠QPW = 140°

The measure of the central angle is congruent to the measure of the intercepted arc.

m∠QPW = m(QW)

m(QW) = 140°

Therefore m(QW) is 140°.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
