<span>8 + 4s – 2s = 16
simplify
8+2s = 16
subtract 8 to both sides
8 +2s - 8 = 16 - 8
2s = 8
divide both sides by 2
2s/2 = 8/2
s = 4
Answer is C. s = 4</span>
Answer:
Step-by-step explanation:
In order to solve this, you would need to multiply the probability of you choosing the one that goes first, so 1 in 16 discs, then the next one so 1 in 15, and so on untill the fifth disc.
So you would have to do this:
That is the probability that the rack ends up in alphabetical order, if you pull discs randomly, 1 in 524160 chances.
Answer: 1661 cm^2
Step-by-step explanation:
The area of a circle is pi*radius^2.
The diameter is given as 46 cm and the radius is 1/2 of the diameter = 23 cm.
Therefore, the area of the circle is pi*23^2 = 529pi = about 1661 cm^2
Answer:
Construct line segment AB of length 7 cm.
From point A, mark an arc taking 5 cm as radius.
From point B, mark an arc taking 4 cm as radius. ...
Extend AO and BO. ...
Similarly mark an arc on extended ray BO of radius 4 cm. ...
Join AD, DC and BC.
