Answer:
126250
Step-by-step explanation:
5.5% of 250000 is 13750 so you multiply 13750 by 9 which = 123750 then you subtract 123750 from 250000 so you get your answer
Hey there :)
Writing in scientific notation means a should be
0 ≤ a < 10
Therefore, 0.000309 will be written as
3.09 x 10ⁿ
3 is the 4th decimal place value
so n = - 4
3.04 x 10⁻⁴
Answer:
<ABC =
(The central angle of a circle is twice any inscribed angle subtended by the same arc).
Step-by-step explanation:
From the diagram, ABC is an inscribed isosceles triangle. But the radius of the circle equals the length AC.
Join P to A and C to form an equilateral triangle. An equilateral triangle has equal sides and angles. So, the value of each interior angle of the equilateral triangle is;
Sum of angle in a triangle = 
So that each interior angle = 
= 
The value of each interior angle of the triangle is
. Thus, <APC =
.
⇒ <ABC =
(The central angle of a circle is twice any inscribed angle subtended by the same arc.)

Answer:
AC = 18
Step-by-step explanation:
Given the question:
<em>In a right triangle, m∠A = 30° and AB = 12√3 (AB is the hypotenuse). How long is AC?</em>
Side AC is adjacent to angle A. Then, by definition of cosine:
cos(A) = adjacent/hypotenuse
cos(A) = AC/AB
AC = cos(A)*AB
AC = cos(30°)*12√3
AC = 18
