Answer:
19 seconds.
Step-by-step explanation:
Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:
1 PM = 13:00
13 - 7 = 6
228/6 = 38
38/2 = 19
Thus, every half hour the clock is delayed 19 seconds.
Any line is 180 degrees, so z is 67 degrees and x is 6.
Answer:
6
Step-by-step explanation:
[x-2]=[4.7-2]=[2.7]=2
f(4.7)=3*2=6
Answer:
FG = 16
Step-by-step explanation:
we can state that ΔEFG ≅ ΔEHG due to the Angle-Angle-Side postulate
this means that FG = GH
we can use this equation to solve for 'x':
x + 11 = 3x + 1
11 = 2x + 1
10 = 2x
5 = x
FG = x + 11 or 5 + 11, which is 16
Answer:
Percentage Error in counting the marbles in the jar is 39.72%
Step-by-step explanation:
Estimated marbles in the jar = 44
Actual marbles in the jar = 73
⇒Error in Marbles = Number of actual Marbles - Estimated marbles
= 73 - 44 = 29
So, the error in counting marbles in the jar is 29.
Now, 
= 
or, Percentage Error = 39.72%
Hence, the Percentage Error in counting the marbles in the jar is 39.72%
