Answer:
Step-by-step explanation:
The house blueprint shows the bedroom is 4 in wide and its actual length is 12 yards wide. This means that every 1 inch on the blue print represents 3 yards on the actual building. The scale is the ratio of the length of a side on the blueprint to the length of a corresponding side on the actual. Therefore, the scale for the blueprint is 3: 1
Therefore, the scale factor is 3
2.3= 2.03 so there for it is equal
Answer:
Congruent and isometries.
Step-by-step explanation:
Congruent meaning the shape is still the same size and shape
(which is true because translations and rotations don't change size or shape)
And isometries because it is one way of mapping points to a different location.
Answer:
12.58 feet.
Step-by-step explanation:
Ron wants to build a 14 ft. ramp with an angle of the rise of 26° and the height of the ramp is about 6.1 ft.
We have to find out the length of the base of the ramp.
Now, the ramp forms a right triangle with the base and the height and here, the hypotenuse of the triangle is the ramp itself i.e. 14 ft.
If the base length is x feet, then we can write using the trigonometry
⇒ x = 14 cos 26° = 12.58 feet. (Answer)
Answer:
Option b) Sample
Step-by-step explanation:
We are given the following in the question:
Survey:
356 surveys on television-viewing habits of American adolescents.
Result:
Average of 3.1 hours per day.
Population and sample:
- Population is a collection of all the possible observation of individuals or variable of interest.
- A sample is always a part of the population.
- It is a subset of population.
For the given survey, those who responded to the survey forms a a sample as it is a part of 356 surveys that is a subset of population.
The correct answer is
Option b) Sample
