Answer:
11.18
Step-by-step explanation:
135.50 x .0825=11.18
Just here to get points sorry
The answer is c I just got this question on an work sheet it’s c
It is given that z varies directly with x and inversely with the square of y so it follows:
It is also given that z=18 when x=6 and y=2 so it follows:
So the equation of variation becomes:
Therefore the value of z when x=7 and y=7 is given by:
Hence the value of z is 12/7 or 1.7143.
Answer:
Actual height of the building is 670 m
Step-by-step explanation:
We have been the actual height of a Ferris wheel which is 134 m. Along with it we are also given the scaled down heights of a Ferris wheel and a building. Using this data we have to find the actual height of a building.
Actual height of Ferris wheel = 134 m.
Height of Ferris wheel using the scale = 0.65 cm
Height of building after using the scale - 3.25 cm
Let, the actual height of building be x meters.
Since, the same scale is being used, the ratio of actual heights to that of scaled down heights must be the same for both objects.
i.e.
Ratio of Actual Height to scale height of Ferris Wheel = Ratio of Actual Height to scale height of the building
Using the values, we get:
The units of actual heights are in meters, so this means the actual height of the building is 670 m
