If you would like to know what is the missing number 7/8 = ?/48, you can calculate this using the following steps:
7/8 = ?/48 /*8*48
7 * 48 = ? * 8
336 = ? * 8 /8
? = 336/8
? = 42
Result: The missing number is 42.
The answer to this question is 12,321
Answer:
6 people will take 16 days
Assumption: they all work at the same rate
8 people-------- 12 days
6 people--------> ?
<u>8x12</u>
6
= 16 days
The length of the sky lift is 3.387.05 ft
Step-by-step explanation;
By an online search, i found that the sky lift
rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such
that:
One cathetus is 1200ft, this is the opposite
cathetus to the angle of 20.75°
The length of the ski lift would be the
hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus=1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse =1200ft/sin(20.759) =3.387.05 ft
The length of the sky lift is 3.387.05 ft
