Answer:
The answer is 144
Step-by-step explanation:
Answer:
40 volcanoes = 100% of them 15% were in California so if we want to know how much % were in Alaska we do 100% - 15% which equals 85%, so 85% were in Alaska. Now to find out how many the geologist visited in each state multiply 40 by the percentage. Number of volcanoes in California = 15% of 40 volcanoes = 0.15 x 40 = 6Number of volcanoes in Alaska = 85% of 40 volcanoes 0.85 x 40 = 34
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
The secant- secant angle 3x is half the difference of the intercepted arcs, that is
3x =
(4x + 50 - 30 )
3x =
(4x + 20) = 2x + 10 ( subtract 2x from both sides )
x = 10
Answer:
The radius is 9.9 units
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
In the right triangle of the figure ABC
Applying the Pythagorean Theorem

substitute the given values

solve for AB

Remember the the side AB of right triangle represent the radius of the circle
therefore
The radius is 9.9 units
M = one unit to the right and four units up.
N = five units to the right and two units up
(to solve these type of questions just plot it first then label what you did in order to plot it in the format i just did) hope that helps :)
