An architect created a scale model of a building that was to be built.

Mathematics
1 answer:
NARA [144]4 years ago
7 0

Answer:

105 ft

Step-by-step explanation:

In this case, the first thing is to calculate the scale, therefore, we must divide the real measurement by the model measurement, like this:

45 ft / 3 ft = 15

Which means that the scale is 15.

Now, to calculate the height, we must multiply the height of the model by the scale, that is:

7 ft * 15 = 105 ft

which means that the height of the building is 105 ft

What is an equation of the line that passes through the points (1,4) and (-2,-8)?
natita [175]

Answer: I know it 4 but I don’t know the equation for it, I can only help you this far.(hope it help)

Step-by-step explanation:

(1,4) and (-2,-8)

(x is the first number of the point which is 1 and -2, y is the second number of the point which is 4 and -8.)

(x1 is 1, it alway the first point they tell you on the problem like (1,-4) is on the problem first so it gonna be x1 and y1, for x2 it -2, it alway the second point in the problem like (-2,-8) is the second point they tell you so it gonna be y1 and y2.)

Do x2 - x1 and y2 - y1(y/x)

-8 - 4/-2 - 1 = -12/-3

-12/-3 divide top and bottom by -3, that would equal to 4

4 consecutive integers add up to 34. Write an equation to find the numbers
Kisachek [45]

Answer:

(n+(n+1)+(n+2)+(n+3))=34

Step-by-step explanation:

(n+(n+1)+(n+2)+(n+3))=34

To make them consecutive, means they have to be one after the other.
You assume one of the numbers are n, to make the other integers consecutive you add 1 then 2 then 3.
