The area of an equilateral triangle is (1/2)bh. The base is 5, so using the Pythagorean theorem we get h by:
5² = (5/2)² +h²
h = √18.75
h = 4.33
So the area of one face is (1/2)(5)(4.33) = 10.825m²
The total area is 4(10.825m²) = 43.3m²
Let K be the number of songs on Kelly's music player,
L be the number of songs on Lou's music player and T be the number of songs on Tiffany's music player.
We know that,
K = 4*L
and
T = 6*L
and also
K + T + L = 682
Then,
4*L + 6*L + L = 682
11L = 682
L = 62
From here we know that
T = 6*62 = 372
K = 4*62 = 248
So Kelly has 248 songs on her music player
Answer:
16 feet
Step-by-step explanation:
We are told that:
Earl attaches a wire from the top of a 16-foot flagpole and stakes it to the ground
Therefore, we can conclude that the Length of the wire = Length of the flagpole
The length of the wire = 16 ft
Therefore, the wire is 16 feet long.
Answer:
1) Negative (because y value decreases from left to right)
2) Undefined (a vertical line has undefined slope because it fails the vertical line test infinite times)
3) Positive (because y value increases from left to right)
