Answer:
B) 8x - 20 + 2x = 11
Step-by-step explanation:
4(2x - 5) + 2x = 11
use pemdas
parenthesis comes first
open the parenthesis
4 * 2x - 4 * 5 + 2x = 11
8x - 20 + 2x = 11
<span>The numbers (not counting 69) are all perfect squares. They are 7 squared, (what should be, possibly) 8 squared, 9 squared, and 10 squared. The next three numbers in the sequence would then be 121, 144, and 169.</span>
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b"
For lines to be parallel, the slopes have to be the same.
The given line's slope is 1/2, so the parallel line's slope is also 1/2.
y = 1/2x + b
To find "b", you can plug in the point (10, -5) into the equation.
y = 1/2x + b
-5 = 1/2(10) + b
-5 = 5 + b Subtract 5 on both sides to get "b" by itself
-10 = b
y = 1/2x - 10 Your answer is D (you could have just found the slope to get your answer, since all the slopes are different)
Helen needs a replacement ball bearing whose radius is 5.99mm
A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r (radius) away from a given point (center). It is perfectly symmetrical, and has no edges or vertices.
The formula of surface area of the sphere is 
where r represents radius
Given: Surface area of ball = 452.16
Using formula we get,
= 452.16
r^2 = 452.16/4
r = 5.99 mm
Thus Helen needs a replacement ball bearing whose radius is 5.99mm
