If disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion, then income is $_____ trillion. Plea
Serjik [45]

Answer:

c) $22 trillion.

Step-by-step explanation:

We have been given that disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion. We are asked to find income in trillions.

\text{Disposable income}=\text{Income}+\text{Transfers}-\text{Taxes}

\$20=\text{Income}+\$4-\$6, where each amount is in trillions.

\$20=\text{Income}-\$2

\$20+\$2=\text{Income}-\$2+\$2

\$22=\text{Income}

Therefore, the income is $22 trillion.

5. The measure of an intercepted arc is 86, and the measure of the inscribed angle creating the intercepted arc is 3x +
Nonamiya [84]

Answer:

Th correct option is D. 13

Therefore the value of x is 13.

Step-by-step explanation:

Given:

measure of an intercepted arc = 86°

Center Angle = 86°

measure of the inscribed angle creating the intercepted arc= (3x+4)°

Angle Inscribed in arc = (3x+4)°

To Find:

value of x = ?

Solution:

Inscribed Angle Theorem:

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

\textrm{Angle Inscribed in arc}=\dfrac{1}{2}\textrm{Center Angle}

Substituting the values we get

3x+4=\dfrac{1}{2}86=43\\\\3x=39\\\\x=\dfrac{39}{3}=13\\\\x=13

Therefore the value of x is 13.
