Answer:
500 millilitres
Step-by-step explanation:
Mass = Concentration x Volume
This rearranged gives:
Volume = Mass / Concentration
= 150 / 0.3 = 500 millilitres
The sum of 3.0478 and 4.92 is 
, which have 5 significant digits.
<u>Step-by-step explanation:</u>
We have , 
and 
. The significant digits of a number are digits that includes all digits except:
- All leading zeros. For example, "013" has two significant figures: 1 and 3;
- Trailing zeros when they are merely placeholders to indicate the scale of the number and ,
- Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment supports.
Here and with significant digit rules 
. Now, Sum of both numbers = 
⇒Sum of both numbers = 
⇒Sum of both numbers =
∴ The sum of 3.0478 and 4.92 is , which have 5 significant digits.
Answer:
29
Step-by-step explanation:
using pemdas, you first need to solve 3² which is 9. Then you do what's in the parenthesis (4-1) which is 3. you'll first multiply 9 and 3 (27) add the 2 and there's your answer, 29.
Answer:
radius = circumference / (2 * PI)
radius = 5.8378033126
Circle Area = PI * radius^2
Circle Area = PI * 5.8378033126^2
Circle Area = PI * 34.0799475167
Circle Area = 107.07 square units
Step-by-step explanation:
Answer:
The answers provided aren't reasonable for this graph.
Step-by-step explanation:
The graph's y-intercept is -2, since that is the point where the line intersects the y-axis. The slope is 3x, because the distance from one point to the next is 3 up, 1 right. So the equation for the graph is y = 3x - 2.
