X+10=105
105-10=95=x
x = 95
Answer:
x= 16
Step-by-step explanation:
8x + 50 = 178
8x = 178- 50
8x = 128
x = 128/8
x = 16
Answer:
Step-by-step explanation:
So, according to the law of Sines, we have
![\frac{Sin(A)}{a} = \frac{Sin(b)}{b}](https://tex.z-dn.net/?f=%5Cfrac%7BSin%28A%29%7D%7Ba%7D%20%3D%20%5Cfrac%7BSin%28b%29%7D%7Bb%7D)
In our case, we have S and R, so...
![\frac{Sin(S)}{s} = \frac{Sin(R)}{r}](https://tex.z-dn.net/?f=%5Cfrac%7BSin%28S%29%7D%7Bs%7D%20%3D%20%5Cfrac%7BSin%28R%29%7D%7Br%7D)
And we want to isolate R...
![r = sin^{-1} (\frac{Sin(S) * r}{s} ) = sin^{-1} (\frac{Sin(52) * 32}{26} ) = 75.90](https://tex.z-dn.net/?f=r%20%3D%20sin%5E%7B-1%7D%20%28%5Cfrac%7BSin%28S%29%20%2A%20r%7D%7Bs%7D%20%29%20%3D%20sin%5E%7B-1%7D%20%28%5Cfrac%7BSin%2852%29%20%2A%2032%7D%7B26%7D%20%29%20%3D%2075.90)
the angle of R is then 75.90 degrees.
Answer:
19.08
Step-by-step explanation:
each gal = $2.12
gals filled = 9
9 x 2.12 = 19.08
Answer:
B. There were 60 nano-related patents granted in 1991
Step-by-step explanation:
In the expression:
60⋅1.2^t
t is years after 1991, that is, in the year 1993, t = 2
60 is the value of the expression at t = 0, then it represents the amount of nano-related patents granted in 1991
