i know the answer it's the first one
on the left
4. as a decimal = 1.8 then to a percent = 180%
5. it's already a decimal so it = 0.15%
6. also already a decimal so it = 275%
to get from a decimal to a percent, move the decimal 2 spaces to the right and add a percent symbol at the end
Answer:
Option D, x = 1
Step-by-step explanation:
In order for that equation to equal to zero, you need the numerator (the top) to equal zero and the denominator (the bottom) to equal literally anything BUT ZERO.
To satisfy the first part we set the top binomial equal to zero.
x - 1 = 0
x = 0 + 1
x = 1
Plug in x = 1 to the bottom to see if it satisfies to second part; we're looking for everything but zero.
(x - 3)(x + 1)
(1 - 3)(1 + 1)
(- 2)(2) = - 4
Your answer is x = 1, option D.
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.
