Answer:
The inequality which represents the situation is 
.
Step-by-step explanation:
Given:
Number of miles to complete the race = 40 miles.
We need to write the inequality to represent the situation.
Solution:
Let 't' represent the time of a runner who qualifies for the championship.
SO now we can say that;
time of a runner who qualifies for the championship should be less than Number of miles to complete the race.
framing in equation form we get;
Hence The inequality which represents the situation is .
Answer:
-4<3, 5>-5, -6<0, -4>-12, -9<1, -8<100, -90<5, -3<-2, -7<-5, 10>3
Step-by-step explanation:
The figure shows that N is the vertex of a right triantle.
The opposite leg to N measures 5.74, the adjacent leg to N measures 4 and the hypotenuse measures 7.
Then you can states these ratios:
sin(N) = opposite leg / hypotenuse = 5.74 / 7 => N = arcsin(5.74 / 7) = arcsin(0.82) = 55.08 °.
cos(N) = adjacent leg / hypotenuse = 4 / 7 => N = arccos(4/7) = 55.15°
tan(N) = opposite leg / adjacent leg = 5.74 / 4 => N = arctan (5.74/4) = 55.13°.
Of course, you do not need to do the three calculations. I did it just to show you.
Answer: the value of N to the nearest whole degree is 55°
Answer:
y=42 degrees.
Step-by-step explanation:
The sum of angles in a triangle = 180 degrees.
One angle in that small triangle is y, one is 48, and one is unknown.
The sum of angles on one line is 180 degrees.
One of the angles on the line that unknown angle lies on is 90 degrees, so the unknown angle is 90 degrees, too.
90 + 48 = 138
180 - 138 = 42.
