Answer:
D) 200
Step-by-step explanation:
To find what x equals you have to use the expression:
is over of equals percent over 100
In this problem you are given the percent, 65%, and the is, 130.
So we are trying to find the of so you would substitute of with x.
So 130/x = 65/100
Now you would do Cross Product Property to find x.
So 130*100 = 13000
65*x = 65x
65x = 13000
65/65 = 1
13000/65 = 200
x = 200
So 65% of 200 is 130

Answer:
sec Θ = 
Step-by-step explanation:
Using the trigonometric identity
sec²Θ = tan²Θ + 1
Since 270° < Θ < 360° ← that is fourth quadrant, then
sec Θ > 0, thus
sec²Θ = (- 
)² + 1 = 
+ 1 = 
, then
sec Θ = 
=
Answer:
D) 30
Step-by-step explanation:
3(a + 4b)-6 = 3 ( 4 + 4*2) - 6
= 3( 4+8 ) - 6
= 3*12 - 6
= 36 - 6 =30
