Answer:

9. 40°

10. 50°

11. 270°

12. 310°

Step-by-step explanation:

m∠BPC = 40° because it is complementary to ∠APB, which is 50°.

Arc AB is 50° because it will be equal to the central angle, which is 50°.

Arc ADC is 270° because it will be equal to the central angle, which is 270°.

Arc ADB is 310° because it will be equal to the central angle, also 310°.

babymother [125]

Answer:

Shipping Cost of small boxes = x = $7

Shipping Cost of large boxes = y = $15

Step-by-step explanation:

Let us represent

Shipping Cost of small boxes = x

Shipping Cost of large boxes = y

The postal service offers flat-rate shipping for priority mail in special boxes.

Today, Kylie shipped 4 small boxes and 4 medium boxes, which cost her $88 to ship.

4x + 4y = 88...... Equation 1

Meanwhile, Trevor shipped 9 small boxes and 4 medium boxes, and paid $123.

9x + 4y = 123 ..... Equation 2

Combining both Equations

4x + 4y = 88...... Equation 1

9x + 4y = 123 ..... Equation 2

Subtract Equation 1 from Equation 2

5x = 35

x = 35/5

x = $7

Solving for y using Equation 1

4x + 4y = 88...... Equation 1

4($7) + 4y = 88

28 + 4y = 88

4y = 88 - 28

4y = 60

y = 60/4

y = $15

Shipping Cost of small boxes = x = $7

Shipping Cost of large boxes = y = $15

Martin used some apples to make muffins. Omar used some apples to make applesauce. Omar used 5 fewer than half as many apple as

Anon25 [30]

Answer:

A. 1.5a - 5, where 'a' is the number of apples used by Martin

B. Martin could not have used 10 apples, because that would mean Omar used none.

Step-by-step explanation:

Let 'a' represent the number of apples that Martin used. Since Omar used '5 fewer than half as many as Martin':

0.5a - 5 = the number of apples used by Omar

A. The total of all the apples:

a + 0.5a - 5 = 1.5a - 5

B. If Martin used 10 apples:

a = 10

0.5(10) - 5 = 0, which means Omar would have used no apples to make applesauce
