Given:

m\angle ABC=60

To find:

The m\angle ADC.

Solution:

In circle B, \angle ABC is central angle and \angle ADC is inscribed angle from two points A and C.

According to central angle theorem, central angle is always twice of inscribed angle.

m\angle ABC=2(m\angle ADC)         [Central angle theorem]

60=2(m\angle ADC)

Divide both sides by 2.

\dfrac{60}{2}=m\angle ADC

30=m\angle ADC

Therefore, m\angle ADC=30.

Ganezh [65]

Answer:

June has 7 green and 28 blue marbles

Step-by-step explanation:

b + g = 35

b = 4g

Use substitution method to solve them simultaneously

4g + g = 35

5g = 35

g = 7

b = 4g = 4(7) = 28

b = 28, g = 7

She has 7 green and 28 blue marbles

A bathtub contains 20 gallons of water. After the drain is opened, there are 14 gallons of water remaining after 30 seconds. Usi
leva [86]

Answer

a decrease of 0.2 gallons per second

Explanation

The drain was open for 30 seconds.

The water that ran out for 30 seconds = 20 - 14

= 6 gallons

Rate of decrease = (change in gallons)/(time taken)

= 6/30

= 0.2

The rate of change in the amount of water remaining in the tub per second will be the same as the one that ran out since the outlet is the same.

So the correct answer from the choices is "a decrease of 0.2 gallons per second".

If the spray paint costs approximately $1.50 per foot of coverage, how much should the coach budget for the spray paint?
torisob [31]

Since the cost of the spray paint is approx $1.50,

The range for the cost of the spray paint is'

\pm0.05\text{ dollars}

Therefore, the coach budget should be between,

\begin{gathered} \text{for }+0.05\text{ dollars,} \\ =1.5+0.05=1.55\text{ dollars and,} \\ \text{for -0.05 dollars,} \\ =1.5-0.05=1.45\text{ dollars} \end{gathered}

Hence, the budget of the coach should be between $1.45 and $1.55.
