Answer:
x=22°
Step-by-step explanation:
Opposite angles are equal, so that must mean that:
3x-14 = 4(x-9)
expand the brackets.
3x-14 = 4x-36
And then rewrite to get x on one side, by minusing 3x on both sides.
-14=x-36
Add 36 on both sides.
22 = x
so, x=22°
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
Answer:
below
Step-by-step explanation:
Notice that each time we add a an odd number of squares to create a new square
each time we add an odd number we create a perfect square
a perfect square.
- the first square has only one small square ( )
- the second one has 4 small squares ( )
- the third has 9 squares ( )
A perfect square is written as:
- P = n²
- P is the perfect square
- n is a positive integer ( since we are working with squares)
to get the first square we replaced n with 1, to get the second one we replaced it with two and so on ...
So the formula is:
Answer:
308
Step-by-step explanation:
Hello the answer is
14 times 44 = 616
