well, we don't know, however we know from the pythagorean theorem that the square of the two perpendicular legs added together give the slanted leg square, or namely that a² + b² = c², let's see, hmmm say a = 11in and b = 14in
Answer:
(-2,-10)
Step-by-step explanation:
So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):
5x=9x+8
Subtract 5x from both sides:
0=4x+8
Subtract 8 from both sides:
-8=4x
Divide both sides by 4:
x=-2
If x=-2, then we can just plug it back into the first equation:
y=5(-2)
Simplify:
y=-10
Answer:
D. 64 should be the answer
Step-by-step explanation:
length x width x height
4 x 4 x 4
4^2
64
Add both sides by 16
so you'll have x^4 =16
take the 4th root of both sides and you'll get x= 2
Step-by-step explanation:
Probability that Dan chooses a Green card = 0.2
Probability that Esther chooses a Green card = 0.2 (same set of cards = same probability)
Since they are independent events,
total probability = 0.2 * 0.2 = 0.04.
