Answer:5/6
Step-by-step explanation:
Ok so ° = negative
1.0x10°2
_______
8.9x10°6
would be solved like 1x(-10x10)= -100
8.9x(-10x10x10x10x10x10)=
8.9x-1000000=
8900000
and then you do the rest you do the rest
Answer:
7, 12, 13
Step-by-step explanation:
Use the Pythagorean theorem equation on all of them. The one that does not make the equation true is the answer.
a^2 + b^2 = c^2
A.
a^2 + b^2 = 18^2 + 80^2 = 6724
c^2 = 82^2 = 6724
Right triangle.
B.
a^2 + b^2 = 7^2 + 12^2 = 193
c^2 = 13^2 = 169
Not a right triangle.
C.
a^2 + b^2 = 3^2 + 4^2 = 25
c^2 = 5^2 = 25
Right triangle.
D.
a^2 + b^2 = 45^2 + 60^2 = 5625
c^2 = 75^2 = 5625
Right triangle.
Answer: 7, 12, 13
Following the rules of PEMDAS:
We would do exponents before the division
27 ^ 2 = 729
27 ^ 4 = 531,441
729/531441/3 = 0.000456247 approximately
Subtract 5 from each side. Use MAN strategy to determine that x = 5 and x = -1.
