Answer:
0.25. or 1/4
Step-by-step explanation:
The probability that the first coin will be heads is 0.5. The probability that the second coin will be heads is 0.5. So the probability that the first two coins will be heads is 0.5 * 0.5 = 0.25.
Since the third flip can be either heads or tails, this has a probability of 1.0.
So the probability you want is 0.25 * 1.0 = 0.25. (or if you want a fraction it is 1/4)
Answer:
-25 = b -13
Add 13 to both sides. You get -12 = b
Answer:
r = 4.5 ft
Step-by-step explanation:
Circumference of circle = πd
πd = 9π ft
d = 9π ÷ π
d = 9 ft
Radius = d ÷ 2
= 9 ÷ 2
= 4.5 ft

Step-by-step explanation:</h2>
A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. So in this exercise we have three prisms. The first one is a rectangular prism having lengths in units, the second one is a cube having lengths in centimeters and the third one is another cube having lengths in inches. A <em>rectangular prism</em> is a solid whose base is a rectangle while a <em>cube</em> is a prism whose sides all have the same length.
FOR THE RECTANGULAR PRISM:
Multiplying the three dimensions of a rectangular prism: length, width and height, gives us the volume of a prism:
![V=L\times W\times H \\ \\ V=5\times 2 \times 4 \therefore \boxed{V=40units^{3}}](https://tex.z-dn.net/?f=V%3DL%5Ctimes%20W%5Ctimes%20H%20%5C%5C%20%5C%5C%20V%3D5%5Ctimes%202%20%5Ctimes%204%20%5Ctherefore%20%5Cboxed%7BV%3D40units%5E%7B3%7D%7D)
FOR THE CUBES:
If the edge length of a cube is S, then the volume can be found as:
![V=S^{3}](https://tex.z-dn.net/?f=V%3DS%5E%7B3%7D)
<u>Cube of 1 cm on each side:</u>
![S=1cm \\ \\ V=1cm^{3}](https://tex.z-dn.net/?f=S%3D1cm%20%5C%5C%20%5C%5C%20V%3D1cm%5E%7B3%7D)
<u>Cube of 1 in on each side:</u>
![S=1in \\ \\ V=1in^{3}](https://tex.z-dn.net/?f=S%3D1in%20%5C%5C%20%5C%5C%20V%3D1in%5E%7B3%7D)
Simple, the answer to this is...
two angles that add up to be the sum of 90°
Now, a quick tip.
To know the difference between supplementary (180°) and complementary (90°) angles...
the s in supplementary can be viewed as an 8, while in complementary the c can be viewed as a 9....
Thus, your answer....C.
