Hey there!
Since 2 goes into 8, you would simplify. You would get 1 inch and 4 miles. Next, set up a ratio. The ratio is 1 inch: 4 miles. So for every inch on the map, there is 4 miles.
I hope this helps!
Answer:
Step-by-step explanation:
a=42,b=58,A=36°
![\frac{sin B}{b} =\frac{sin~ A}{a} \\sin~B=\frac{b \times ~sin~ A}{a} \\\\sin~B=\frac{58 \times sin~36}{42} \\B=sin ^{-1}( \frac{58 \times sin~36}{42} ) \approx 54^\circ](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%20B%7D%7Bb%7D%20%3D%5Cfrac%7Bsin~%20A%7D%7Ba%7D%20%5C%5Csin~B%3D%5Cfrac%7Bb%20%5Ctimes%20~sin~%20A%7D%7Ba%7D%20%5C%5C%5C%5Csin~B%3D%5Cfrac%7B58%20%5Ctimes%20sin~36%7D%7B42%7D%20%5C%5CB%3Dsin%20%5E%7B-1%7D%28%20%5Cfrac%7B58%20%5Ctimes%20sin~36%7D%7B42%7D%20%29%20%5Capprox%2054%5E%5Ccirc)
Answer:
Don't be lazy, do it by yourself for more brain work!
Step-by-step explanation:
The answer is B because in g(x)=x+3 x=2 so it would be g(2)=2+3 so g(2)=5. So you plug in five and do f(5)=5*3+4 and 5 to the power of 3 is 125 and you add 4 so you get 129
