Answer:
Step-by-step explanation:
ntroduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
80% = 80/100 = 80 ÷ 100 = 0.8
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 80% of what number = 40?
80% of what number = 40 is equivalent to:
80% × ? = 40
80% × ? = 40
? =
40 ÷ 80% =
40 ÷ (80 ÷ 100) =
(100 × 40) ÷ 80 =
4,000 ÷ 80 =
50
Answer:
58.8Joules
Step-by-step explanation:
The gravitational potential energy = mgh
m is the mass = 2kg
g is the acceleration due to gravity = 9.8 m/s²
h is the height = 3m
Substitute;
GPE = 2 * 9.8 * 3
GPE = 6 * 9.8
GPE = 58.8Joules
Hence the Gravitational Potential Energy of the block is 58.8Joules
Answer:
Step-by-step explanation:
We have to find the relative frequency for each event.
The relative frequency of a event is the number of times the event event happened by the total number of events.
There are 16+18+19+19 = 72 events.
X can be 4,5,6 or 7.
We have that
Let the ∠C be : θ
From the figure, We can see that the Side which is opposite to angle θ is measuring 7 units
Also, We can notice that Hypotenuse is 11 units
As we are dealing with opposite and hypotenuse, we can clearly use Sinθ to find out the angle θ
We know that :
<u>Answer</u> : The measure of ∠C to the nearest degree is 38°
