Since the question specifically asks about using a calculator, there's no point explaining how to do it (mostly because the buttons you have to press vary from model to model.
All we can tell you is that the calculator, depending on how many decimal digits it can store, will return something like 0.803802...
Even if there were millions of digits after the decimal point, that would still be an approximate value, since this number is irrational, i.e. it has infinite, non-repeating decimal digits.
If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x=2 :)))

Answer:
a 
b 
c 
Step-by-step explanation:
Given
--- number of times
--- faces of a coin
First, is to determine the sample size.
This is calculated as:
Solving (a): First and last slip is head
This event is represented as:
The probability is calculated as:
b) At least 2 consecutive flips that is heads.
This event is represented as:
The probability is calculated as:
c) First is tail and at least 2 consecutive flips is head.
This event is represented as:
The probability is calculated as:
Answer:
A)
P=2x+2\pi rP=2x+2πr
B)
x=\frac{1}{2}(P-2\pi r)x=
2
1
(P−2πr)
C)
x\approx173\text{ feet}x≈173 feet
Step-by-step explanation:
So, the track is composed of a rectangle and two semicircles.
The side length of the rectangle is x, and the radius of the semicircles is r.
Part A)
The perimeter is simply the length around the figure.
We can see that the perimeter will be equivalent to two times x plus two times the circumference of the semi-circles.
if your multiplying its 12
