To simplify this ration we need to divide each member of ration with same number.
We can start with 2.
18/2: 30/2 : 72/2 or
9:15:36
Now we can divide by 3 because 15 isn't divisible by 2.
we get:
3:5:12
This ration cannot be simplified further.
Answer:
approx. 24.6 ft
Step-by-step explanation:
x=the distance of the fire from the base of the tower
200ft=the height of the tower
7 degrees=the angle of depression
Using these values you can draw a diagram that highlights that you need to use trig. to work out the answer.
Using Tan:
Tan 7=x/200 ft
multiply both sides by 200 ft
200*tan 7=24.55691218
approx. 24.6 ft
X is 3
y is 2
you have to replace x with a zero and divide 12 by it and then you do the same for y
Answer:
There are many ways we can write one of them being that we just write 11 fives being multiplied against each other like the following:
This can seem very repetitive which is why powers are a lot more helpful. We can also rewrite using the power in the bottom of a fraction. The way that we do this is put on the bottom which can then be flipped to the top with a positive power and will be the same.
The final way that we can rewrite is by using several different powers. We can do which will equal the same thing as because the base is the same and what we basically do is just add up the powers together to get back to 11.
The base is 6.
In order to find this, we can set the legs equal to each other since legs have the same length in an isosceles triangle.
x + 1 = -x + 7
2x + 1 = 7
2x = 6
x = 3
Now that we have the value for x, we can plug into the equation to get the value for the base.
3x - 3 = base
3(3) - 3 = base
9 - 3 = base
6 = base
