A new car is purchased for $40,000 and over time its value depreciates by one half
every 3 years. What is the value of the car 17 years after it was purchased, to the
nearest hundred dollars?
Answers
9514 1404 393
Answer:
$800
Step-by-step explanation:
The value formula can be written ...
y = 40,000(1/2)^(t/3)
Using t=17, this becomes ...
y = 40,000(1/2)^(17/3) ≈ 800
The value of the car after 17 years is about $800.

I believe the second one : drawing a number from a hat, not replacing it, and then drawing a second number
Answer:
The first choice.
Step-by-step explanation:
An independent event is an event where the probability of the event doesn't affect the probability of the other.
Randomly choosing a marble from a bag, replacing it, and choosing again reaching into your pocket and pulling out two dimes out of 20 coins.

There is one third of a pie shared equally between 5 children. How much of the pie does each child receive? one ninth pie one fifteenth pie one eighteenth pie one twentieth pie
Answers
Answer:
Each of the 5 children receive one fifteenth pie
Step-by-step explanation:
Given:
One third of a pie shared equally between 5 children.
To find:
Amount of the pie with each of the 5 children.
Solution:
Number of children = 5
Also, one third of a pie shared equally between 5 children.
So,
Amount of the pie with each of the 5 children [tex]=\frac{\frac{1}{3} }{5}=[/tex] [tex]\frac{1}{15}[/tex]
Hence, each of the 5 children receive one fifteenth pie.
first we need to ask our self the question
Question: There is one third of a pie shared equally between 5 children. How much of the pie does each child receive?
__________________________________________________________
next we need to do the math. 1/3 divided by 5
i recommend turning the fractions into decimal points and then dividing them. after doing that we have the answer 0.067. but that is not a option. so turn it into a fraction! and we get 1/15.

4x + 3y = 10
9x - 4y= 1
Answers
4x+3y=10 <— you solve for x and get x=5/2-3/4y
then substitute the value of x into 9x-4y=1 to get
9(5/2-3/4y)-4y=1
solve the equation for Y
y=2
now sub the value of y into x=5/2-3/4y
x=5/2 - 3/4 times 2
your answer would be x = 1
therefore you get (x,y) (1,2)
After solving the given equations, the value obtained for x and y will be equal to (1, 2).
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given equations in the question,
4x + 3y = 10 (i)
9x - 4y = 1 (ii)
Multiply equation (i) by 9 and multiply equation (ii) by 4
36x + 27y = 90
36x - 16y = 4
A similar term of x will cancel out from here.
y = 86/43
y = 2
Put y = 2 in equation (i)
4x + 3(2) = 10
4x = 4
x = 1

What are rational and irrational numbers and how are radicals related to rational exponents?
Answers
A rational numbers is any number that can be turned into a fraction/ratio. (Ex. 8, 0.75, 1/3). An irrational number is anything that can't be turned into a fraction/ratio. (Ex. Pi, square root of 2). Radicals and rational exponents are related because radicals can be converted into rational exponents.
Answer:
Any number that can be written as a fraction with integers is called a rational number. An irrational number is a number that cannot be expressed as a fraction for any integers. Radicals are related because for irrational numbers they cannot be simplified under the radical and you use a radical on the exponent to cancel it out, hope this helps!

HELP PLZZ I would really really appreciate it
Answers
Answer:
31
Method:
X + 21 = 52 is the same as 52 - 21 = x. 52 - 21 = 31 so x = 31
In algebraic equations, you always want to isolate the variable (x) so To do that you would subtract 21 from both sides, and then you would do 52 - 21 = 32
x + 21 = 52
-21 = -21
