Answer:
d) sin(45°) = 13/
Step-by-step explanation:
Trig ratios:
sin(x) = O/H
cos(x) = A/H
tan(x) = O/A
where x is the angle, O = opposite side to angle, A = adjacent side to angle, and H = hypotenuse
From inspection, we have been given the measure of the side OPPOSITE to the angle and the measure of the HYPOTENUSE.
angle = 45°
opposite side = 13
hypotenuse =
Therefore, substitute these values into the sine trig ratio:
⇒ sin(x) = O/H
⇒ sin(45°) = 13/
Answer:
2.5 hours
you would take your total miles 95 and divide it by 38 ans it gives you 2.5
Answer:
205 minutes
Step-by-step explanation:
If Monica has already practiced 18% of her time, we know that she has practiced 
. If this 18% corresponds to 45 min, we can have the following equation: 
. We can rearrange the equation to find the value of x by doing 
, so she practices 250 min every Wednesday. If we subtract the time she has already practiced (45 min) we find out she still has to practice more 205 min.
Answer: 15%
Because 3162.50 divided by 2750 is 1.15
1.15 x 100 is 115%
115-100 = 15% increase
