So hmm check the picture below
and since you already covered solving system of equations, surely you'll breeze right through B)
Answer:
213
Step-by-step explanation:
The circumference of the wheel is given by
C=2πr=πd
Where d is diameter, r is radius and c is circumference
The number of revolutions N multiplied by circumference should yield the total distance
N*πd= Distance
Given distance of 20, 000 cm and diameter of 30 cm
30πN=20000
Making N the subject of formula
N=20000/(30π)=212.20659078919378102517835116335248271261
Rounded off, about 213 revolutions are required
Answer:
<h3>The answer is option A</h3>
Step-by-step explanation:
Angles in a triangle add up to 180°
Since it's a right angled triangle one of it's angles is 90°
So for angle F we have
F + 25 + 90 = 180
F = 180 - 115
<h3>F = 65°</h3>
To find GH we use tan
tan 25 = FG / GH
FG = 7m
tan 25 = 7 / GH
GH = 7 / tan 25
<h3>GH = 15.0 m</h3>
To find FH we use sine
sin 25 = FG / FH
sin 25 = 7 / FH
FH = 7/sin 25
<h3>FH = 16.6 m</h3>
Hope this helps you
