Answer:
352 cm
Step-by-step explanation:
The circumference of a circle is given by the radius times 2 times π:
2•56•3,14 = 351,68 ≈ 352 cm
I used geogebra for this. I hope this helps
Find the rate at which you work, that is, the # of walls painted per hour:
13 1/3 walls 40/3
------------------ = ---------- wall per hour
14 1/4 hr 57/4
Keep 40/3 as it is; invert the divisor (57/4) and then multiply the result by 40/3:
40 4 160 wall
------ * ------ = --------------- = approx. 0.94 wall in one hour, or 160/171 wall / hr
3 57 171 hr
Answer:
None of the pairs of expressions are equal
Step-by-step explanation:
• 2n ≠ 2 +n
2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.
•n² ≠ 2n
n²= n ×n
2n= 2 ×n
• 2n² ≠ (2n)²
Note that in the latter, there is a bracket which means that the square applies to both 2 and n.
(2n)²
= (2)² × n²
= (2 ×2)(n²)
= 4n²
Thus, none of the pairs of expressions are equal.
Answer:
x=9
Step-by-step explanation:
2(10-22×0)=(2x+2)
Applying BODMAS
2(10-0)=(2x+2)
2(10)=2x+2
2x+2=20
2x=20-2
2x=18
x=9
