B
The purple balls constitute 1/3 of the amount of balls there, so you’re that likely to pluck one out.

58,927 move to the decimal left 4 place
olga nikolaevna [1]
So in the number 58,927 your decimal point starts after the 7. When you move it to the left four places (four numbers) the decimal is now right after the 5. Your new answer is 5.8927. Hope I helped :D

Indicate whether the following statements are True (T) or False (F).
chubhunter [2.5K]
1.  False because a rational is a fraction or part of a number (\frac{3}{2}, 3.2).  \sqrt{49} = 7

2.  True; a real number is any number that isn't imaginary (i, \sqrt{-1})

3.  True; same reason

4.  True; an integer is any number that can be wrote without a fraction or decimal (the opposite of rational).

5.  True; \sqrt{3} \approx 1.32 and that's a decimal.

6.  True;  the natural number system starts from 0 and counts upwards

7.  True;  reason above

In 2012 your car was worth $10,000. In 2014 your car was worth $8,850. Suppose the value of your car decreased at a constant rat
monitta

Answer:

The function to determine the value of your car (in dollars) in terms of the number of years t since 2012 is:

f(t) = 10000(0.9407)^t

Step-by-step explanation:

Value of the car:

Constant rate of change, so the value of the car in t years after 2012 is given by:

f(t) = f(0)(1-r)^t

In which f(0) is the initial value and r is the decay rate, as a decimal.

In 2012 your car was worth $10,000.

This means that f(0) = 10000, thus:

f(t) = 10000(1-r)^t

2014 your car was worth $8,850.

2014 - 2012 = 2, so:

f(2) = 8850

We use this to find 1 - r.

f(t) = 10000(1-r)^t

8850 = 10000(1-r)^2

(1-r)^2 = \frac{8850}{10000}

(1-r)^2 = 0.885

\sqrt{(1-r)^2} = \sqrt{0.885}

1 - r = 0.9407

Thus

f(t) = 10000(1-r)^t

f(t) = 10000(0.9407)^t

If the measure of the ABC = 40o, which is the measure of arc AC
Assoli18 [71]
With the help of theorems involving circles, assuming that arc ABC is a central angle (meaning both legs of the angle start from the centerpoint), the measure of the inscribed angle is twice that of the central angle. Thus, arc AC is equal to 2*40°= 80°.
