Do the 15 new people fill the gondola?
Answer:
13.5
Step-by-step explanation:
c = 2πr
42.3 = 2(3.14)r
42.3 = 6.28r
6.74 = r
d = r + r
d = 6.74 + 6.74
d = 13.5
Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
Answer:
-49 divided by 7
Step-by-step explanation:
-49 ÷ 7
= <u>-</u><u>7</u>
The problem wants to calculate the percentage error of the measurement of 7cm and if the measurement is uncertain we could use the formula of getting the error by margin of error over measurement time 100% and base on the data, the error would be if the margin error is 7.5 is 107 %.
