As a ratio, 5:86 represents students to teachers
We can set up the equation as 5/86=x/9460
Multiply 9460 to both sides
5x9460/86=x
47300/86=x
x=550
There are 550 professors
Hi :)
Amount financed
495−50
=445
Total interest
(0.18×445×37)÷(2×12)
=123.49
Total paid
445+123.49
=568.49
Monthly payment
568.49÷36
=15.79
Hope it helps
The answer is 58 degrees.
<span>w - amount of wheat purchased
r - amount of rye purchased
12w+15r=18.30 /*2
15w+10r=16.75 /*3
24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25
21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour
From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour</span>
Answer:
6sin^2(x) = 7 - 5cos(x)
6(1 - cos^2(x)) = 7 - 5cos(x)
6 - 6cos^2(x) = 7 - 5cos(x)
6cos^2(x) + 5cos(x) -1 = 0
(6cos(x) - 1)(cos(x) + 1) = 0
cos(x) = 1/6
x = arccos(1/6)
x = 1.40334825 + 2k*pi, 4.87983706 + 2k*pi
cos(x) = -1
x = pi + 2k*pi
