Answer:
Correct choice is C
Step-by-step explanation:
Let x be unknown number.
Three times a number x is
Three times a number is no less than negative six means that the number can be equal to -6, can be greater than -6, but cannot be less than -6.
Thus, the inequality that could be used to solve the problem is
The value of x is 126.87° and the value of y is 53°.
<h3>What is an obtuse and an acute angle?</h3>
An obtuse angle is an angle that is greater than 90° but lesser than 180° while an acute angle is an angle between 0-90°.
From the given information:
sin x° = 0.8
x = sin⁻¹ (0.8)
x = 53.13°
x + 53.1° = 180°
x = 180° -53.13°
x = 126.87°
If cos 127° = -cos y°,
-cos y = -0.6018
cos y = 0.6018
y = cos⁻¹ (0.6018)
y = 53°

Answer:
Step-by-step explanation:
As the line is perpendicular to , we know that the slope of the line is . As it passes through , we know that it should be .
Subtract x from both sides of the equation, this will allow only one side to have a variable.
Answer:
In the allocated budget of $130 , the business person can travel 462.55 miles a day.
Step-by-step explanation:
The daily rate of car service = $37.49
Cost per mile of the car = 20 cents = $ 0.20
Total allocated budget for each day = $130
Now, out of the total budget :
The actual travelling budget = Total Budget - Daily car rate
= $130 - $37.49
= $92.51
So, the actual travelling budget each day = $92.41
Now,
=
or, the number of miles traveled = 462.55 miles
Hence, in the allocated budget of $130 , the business person can travel 462.55 miles a day.
