5.19cm
Step-by-step explanation:
draw perpendicular from the center of the circle to produce a right angle triangle which will have 3cm and an angle of 30 degrees. use tan to find the adjacent line which is the length of the tangent.
So it gives you the "= 210" part of it so you just need to figure out how to write "40% of a number is added to the number"
the questions already tells you that "the number" is "x"
so that means "40% of x is added to x"
instead of writing "add" you can replace it with a plus sign "+"
(40% of x) + x
another way to write 40% of x is 0.40x
so your equation is .4x + x = 210
I would go with the answer B
Answer:
-7
Step-by-step explanation:
To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:
6 - 13 = -7
To check you can do the same thing with other consecutive numbers in the sequence like:
-1 - 6 = -7
So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.
so, what would it be for an actual 15 feet on the drawing then?
