Answer:

What does x equal ? <u>3</u><u>0</u>

What does < ABC equal? <u>100</u>

What does < DBC equal? <u>8</u><u>0</u>

Step-by-step explanation:

(3x + 10) + (2x + 20) = 180 \\ 5x + 30 = 180 \\ 5x = 180 - 30 \\ 5x = 150 \\  x =  \frac{150}{5}  \\  \\  x = 30

3x + 10  = 3(30) + 10 = 90 + 10 = 100

2x + 20 = 2(30) + 20 = 60 + 20 = 80

A naomi's car exponentially depreciates at a rate of 8% per year. if nina bought the car when it was 4-years old for $16,500, .
stich3 [128]

The original price of the car before 4 years will be $23,032.

<h3>What is an exponent?</h3>

Consider the function:

y = P (1 ± r) ˣ

Where x is the number of times this growth/decay occurs, P = original amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction or 100r %

If there is a minus sign, then there is exponential decay happening by r fraction or 100r %

A Naomi's car exponentially depreciates at a rate of 8% per year.

If Nina bought the car when it was 4 years old for $16,500.

Then the original price will be

16500 = P(0.92)⁴

16500 = 0.716P

       P = $ 23,032

DE is tangent to Circle C at point D. <br><br> What is the measure of Enter your answer in the box.
creativ13 [48]

Answer:

39°

Step-by-step explanation:

A radius of a circle (segment CD) drawn to the point of tangency (D) intersects the tangent (line DE) at a 90-deg angle.

That makes m<D = 90.

m<D + m<C + m<E = 180

90 + 51 + m<E = 180

m<E = 39
