Answer:

1,600 dentists were surveyed in total.

Step-by-step explanation:

We can set up a proportion for this problem:

\frac{27}{40} = \frac{1080}{x}\\\\\\

Now we can cross multiply:

27*x = 1080*40\\\\27x = 43,200\\\\27x/27 = 43,200/27\\\\x = 1,600

1,600 dentists were surveyed in total.

PLEASE HELP Triangle ABC is reflected across the y-axis to create Triangle A'B'C'. Which rule describes this transformation?
marta [7]
B because when you reflect over the y axis, the y value stays the same but the x value changes to the opposite of what it was before (for example, the value of x was 8 but when you reflect over the y axis, it changes to -8)

A 5ft 11-inch women cast a three ft shadow. what is the angle that the sun's rays make with the ground?
zepelin [54]
This will involve finding an arctangent.
We'll consider the woman's height as the "opposite" side of a triangle and the shadow as the "adjacent" side.  The angle that the Sun makes equals the arc tangent of that angle.
tan (Sun's angle) = 71" / 36"
tan (Sun's angle) = <span> <span> <span> 1.9722222222 </span> </span> </span>
when we determine the arc tangent of 1.9722222222, it will equal the Sun's angle.
arc tangent of 1.9722222222 = 63.113 degrees
