Step-by-step explanation:
For these problems I used the pythagorean theorem: and SOHCAHTOA
Sin =
Cos =
Tan =
11)
First find the length of the bottom side by using Cos
Then plug it into the formula for the pythagorean theorem to find the hypotenuse
12)
Find the length of the bottom side using Cos
Then plug it into the formula for the pythagorean theorem to find the hypotenuse
13)
Find the length of the other side by using Tan
Then plug it into the formula for the pythagorean theorem to find the hypotenuse
14)
(This is probably an easier way to do these problems)
Find the hypotenuse by using Cos ()
15)
Find the hypotenuse using Sin ()
16)
Find the hypotenuse using Cos ()
3560 * 35/100
3560 * 0.35
= 1246 students lived in other states
Answer: 20
Step-by-step explanation:
Given : The orchestra at millard middle school has 120 members.
Of these 17% are eighth grade students.
i.e. Percentage of eighth grade students in orchestra = 17%
Then, the number of eighth grade students in the orchestra. = (Percentage of eighth grade students in orchestra) x ( Total members in orchestra)
= 17% x 120
[We convert % into decimal by dividing it by 100]
[Round to the nearest integer.]
Hence, the estimated number of eighth grade students in the orchestra is 20.
Subtracting 5z from both sides leaves 2=0, with this there is no solution...hope this helped :)
