5 out of 20 like Star Wars so what value (x) should like Star Wars out of 200. Set up a proportion comparing the two.
x= # of people in 7th gr who like Star Wars
5/20= x/200
cross multiply
(5*200)= (20*x)
1000= 20x
divide both sides by 20
50= x
ANSWER: 50 people in the 7th grade should like Star Wars.
Hope this helps! :)
Sample Response: The graphs are reflections of each other over the y-axis. The graph of g(x) shoes exponential decay, while the graph of f(x) shows exponential growth.
All triangles are similar.
.. x/3 = 27/x
.. x^2 = 81
.. x = 9
.. y = √(x^2 -3^2) = √72
.. y = 6√2
Answer:
tan 1° + tan 2° + tan 3° + tan 84° + tan 90° = tan 180°
Answer:
y=5
Step-by-step explanation:
the line going up and down is the y and the line going left to right is the x so u would go up to until u find the number that fits and it would be y=5
