Answer:
26,910 meters
Step-by-step explanation:
The glacier moves 29.9 meters a day.
In 100 days it will move 29.9(100)=2990 meters.
In 1000 days it will move 29.9(1000)=29900 meters.
29,900-2,990=26,910 meters

Answer:
71.3°
Step-by-step explanation:
A building 62 feet tall casts a shadow 21 meters long . At what angle is the sun shining on the building?
We solve this question using the Trigonometric function of Tangent
tan x = Opposite/Adjacent
Where
Opposite = 62ft
Adjacent = 21 ft
x = Angle
Hence,
tan x = 62/21
x = arc tan (62/21)
x = 71.288262125°
Approximately = 71.3°
So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27
To find the number of questions in the exam, make an equation
(90% =

= 0.9)

=

cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer

90 and 90 cancels out
x = 30So your final answer will be,
there were 30 questions in the exam paper.
