area of 1/6 circle:
= 1/6 * 3.14 * 8^2
= 33.49 ft^2
area of equilateral triangle:
= √3/4 * 8^2
= 27.71 ft^2
Area of shaded = area of 1/6 circle - area of equilateral triangle
= 33.49 - 27.71
= 5.78
= 5.8 ft^2
answer
B. 5.8 ft^2
Answer:
D) infinitely many solutions
Step-by-step explanation:
5 ( x-3 ) - 3x = 8x - 15 - 6x
5x - 3x - 15 = 8x - 6x - 15
2x - 15 = 2x - 15
2x = 2x
Since, equations of both lines are same. Therefore, there are infinitely many solutions.
Answer:
The two angles are 85 and 95 degrees
Step-by-step explanation:
Supplementary angles add to 180
Let x be one angle
The supplement is 10 less, ( x-10)
They add to 180
x+ ( x-10) = 180
2x -10 = 180
Add 10 to each side
2x-10+10 =180-10
2x= 190
Divide by 2
2x/2 =190/2
x=95
The other angle is 95-10 = 85
The two angles are 85 and 95 degrees
Since we want either an e tile OR a y tile, then they are not simultaneous. Thus, we add up the probabilities to form our final probability.
The total number of possibilities is: 5 + 3 + 1 + 2 + 3 + 1 = 15, because there are 15 tiles to choose from.
Now, P(e tile) = 3/15 = 1/5
P(y tile) = 1/15
When we add them up, we get: P(e tile or y tile): 3/15 + 1/15 = 4/15
Thus, we have a 4/15 in choosing an E or a Y tile on the next draw.
The standards that use 2.4 GHz are:
- IEEE 802.11b
- IEEE 802.11g
- IEEE 802.11n (it uses both 2.4 GHz and 5 GHz)
- IEEE 802.11ax (it uses both 2.4 GHz and 5 GHz)
<h3>
What is a wifi standard?</h3>
A wifi standard defines two characteristics of the wi-fi network, which are speed and frequency.
Such that there are two common frequencies, 2.4 GHz (usually with larger speed) and 5 GHz (usually with lower speed)
The standards that use 2.4 GHz are:
- IEEE 802.11b
- IEEE 802.11g
- IEEE 802.11n (it uses both 2.4 GHz and 5 GHz)
- IEEE 802.11ax (it uses both 2.4 GHz and 5 GHz)
