Answer:
- 267/200 = 1.335
- 131/150 = 0.8733...
- 1/10,000 = 0.0001
- 1/12 = 0.0833...
Step-by-step explanation:
It might be helpful to think of the % symbol as being interchangeable with /100.
133 1/2% = (133 1/2)/100 = 267/200 = 1.335
87 1/3% = (87 1/3)/100 = 262/300 = 131/150 = 0.8733333... (repeating 3)
0.01% = 0.01/100 = 1/10000 = 0.0001
8 1/3% = (8 1/3)/100 = 25/300 = 1/12 = 0.0833333... (repeating 3)
F(3)= 2(3)^2-5(3)+9
=2(9)-15+9
=18-15+9
=3+9
=12
f(3)=12 or B
Answer:
y= 4 , x= -1
Step-by-step explanation:
3x-9y= -39
-3x-7y= -25
-16y= -64
y= -64/-16
y= 4
substitute y into any equation
3x -9(4) = -39
3x-36= -39
3x= -39+36
3x= -3
x= -3/3
x= -1
Answer:
r = 28.28
Step-by-step explanation:
you already gave the equation: sin45°= 20/r
you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:
r (sin45°) = 20
Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:
r = 28.28
P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)
