Answer:
B
Step-by-step explanation:
tan45° = 10/x
=> 1 = 10/x
=> x = 10
=> y^2 = 10^2 + 10^2 = 200
=> y = 100*sqrt(2)
=> b
Answer:
y-3x
Step-by-step explanation:
Because it is subtracted from y that meas the y would be first and 3 times x would be 3x because you do not need a sign because it is a variable

Answer and explanation:
Since x = number of true or false questions correct
And y = number of multiple choice questions correct
And each question for x =2 points
each question for y=3 points
since she then needs a total score of more than 93 to pass, we add up total correct questions and
Inequality equation = 2x +3y >93
The relationship between arc, radius, and central angle in radians is:
Θ = s/r
So just plugging in the values:
Θ = (5π/3)/7 = 5π/21 ≈ 0.748 or 0.7
