Answer:
753
Step-by-step explanation:
m^2 =700^2 +460^-2 −2(700)(460)cos78
m^2 = 490000+211600-2(700)(460)(0.207912)
m^2 = 490000+211600-133895.12889
m^2 = 567704.87111
m=753.462=753
120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.
A circle with radius 9 has area 9^2 π = 81π.
So the sector has area 81π/3.
Put another way: The area <em>A</em> of a circular sector and its central angle <em>θ</em> (in degrees) occur in the same ratio as the area of the entire circle with radius <em>r</em> according to
<em>A</em> / <em>θ </em>º = (π <em>r </em>^2) / 360º
==> <em>A</em> = π/360 <em>θ r</em> ^2
In this case, <em>r</em> = 9 and <em>θ</em> = 120º, so
<em>A</em> = π/360 * 120 * 81 = 81π/3
First: Replace “x” with its known value. Since x = 3, plug it into the formula.
• F(3) = 6^3
Second: Solve the formula.
• 6^3 = 6 x 6 x 6 = 216
• F(3) = 216
I answered the last post, the third option is correct
Solution:
<u>Note that:</u>
- Men:Woman = 3:2
- 54 women = Total woman in a company
<u>3:2 can also be written as 3x:2x.</u>
- => Men:54 = 3x:2x
- => 54 = 2x
- => x = 27
- => Men = 3x
- => Men = 3(27) = 81
- => Total employees: 81 + 54
- => Total employees: 135
There are 135 employees in total.
