Find area of circle using radius, divide that by four
Answer: 200
Step-by-step explanation:
first, you set up your proportion. (23% at the top right, 100 at the bottom right, 46 at the top left, and x and the bottom left.) next, you multiply x * 23% = 23x then 46*100 = 4600. 4600 divided by 23 = 200. therefore, x = 200. please let me know if you have further questions!
Good luck !
Answer:
(-9x+7)+(-6x-13)= -15x + -6
Step-by-step explanation:
-9x+-6x = -15x
7+-13=-6
therefore, -15x+-6 = (-9x+7)+(-6x-13)
Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 = ( multiply both sides by 3 )
24 = k
y = ← equation of variation
Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
