The answer to the question above is option D: <span>18/ 9-a. If we try to analyze the word phrase above, this is the algebraic expression that matches it. When we say quotient, this is the number or the result of the division between two numbers. So the quotient of 18 and 9, this means that the answer of 18 divided by 9. And then, less than a. Less than a here means subtraction or minus. Therefore, this makes -a. </span>
Answer:
Step-by-step explanation:
whole number No
integer No
rational
: No, because pi is irrational.
irrational: YES. π/2 is the ratio of pi to 2, BUT pi is irrational.
All of the above options are true, so the answer is choice D.
10.
5 multiplied by 2 "5 x 2" = 10
Cos(theta) = adjacent/hypotenuse
cos(theta) = 6/20
cos(theta) = 0.3
Use the inverse cos or cos^-1 on your calculator to get the angle
theta = 72.5
