Answer:
20 m
Step-by-step explanation:
Given that :
Scale of 1 : 50 is used to make a model
If the model has a height of 40 cm ; the height of the house is:
Then, the actual height of the house is (40 * 50) = 2000 cm
Thus the height of the house in metre is :
100cm = 1 meter
2000 cm = 2000 / 100
2000 cm = 20 meter
Height of house in meter = 20 meter

Answer: x = 155</h3>
Explanation:
Glue the two right triangles together to form one larger triangle.
The angle adjacent to the 60 degree angle is 180-60 = 120 degrees.
The angle adjacent to x is 180-x
The larger triangle has the interior angles of:
Those three angles add to 180 (which is true of any triangle)
35+120+180-x = 180
335-x = 180
-x = 180-335
-x = -155
x = 155
Or you can note that 35+120 = 155 which is the summation of the interior angles that aren't adjacent to exterior angle x (refer to the remote interior angle theorem, aka the exterior angle theorem).
f(x) = log2 x
f(40) = log2 40
40 = 2^y
2^5 = 32 and 2^6 = 64
so f(40) lies between integers 5 and 6.
Answer:
I would say B
Step-by-step explanation:
A. would make no sense and the graph will always have a straight line unless its compairing something and it does not have anything to do with 0 because it shows where it starts
