Answer:
I think <2 = 37⁰
Step-by-step explanation:
if I remember correctly, if its straight across from it, it must be the same angle.
which means that 1 and 3 must have the same angle, and 2 must have the same angle as the other side, meaning its angle is 37⁰.
-2/3 is a rational number
0.1111.... =1/9 - rational number
-2/3*1/5= -2/15 rational
1/9*1/5=1/45 rational
correct answer A and D
π and √11 are irrational numbers, and when they are multiplied by rational number, they will give irrational number.

1oz=1000cg
32.5*1000=32500cg
Answer:
The measured weight of the water = 4.93 g
The percentage error in measured value = 1.4%
Step-by-step explanation:
Given:
Weight of the 10-mL graduate = 42.745 g
Combined weight of graduate and 5 mL water = 47.675 g
5 mL of water should weight = 5 g
thus, actual value of 5 mL water = 5 g
Now,
The measured weight of the water
= (Combined weight of graduate + 5 mL water) - Weight of the 10-mL graduate
= 47.675 g - 42.745 g
= 4.93 g
The percentage error in measured value
= 
= 
or
= 1.4%
Y=3x²-6x+4
to put in vertex form, make a square by adding (half of b)²
but first, we have to make a=1 by take out the 3:
y=3(x²-2x)+4
b=-2, half of b=-1, (-1)²=1, so add 1, then subtract 1 inside the parenthesis:
y=3(x²-2x+1-1)+4
make the square: y=3[(x-1)²-1]+4
simplify: y=3(x-1)²-3+4=3(x-1)²+1
so the answer is A.
