Answer:60 balloons
Step-by-step explanation: 0.80 times 75 is 60 and 125- 65 is 60
For this problem, we are going to use the <em>law of sines</em>, which states:
![\dfrac{\sin{A}}{a} = \dfrac{\sin{B}}{b} = \dfrac{\sin{C}}{c}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Csin%7BA%7D%7D%7Ba%7D%20%3D%20%5Cdfrac%7B%5Csin%7BB%7D%7D%7Bb%7D%20%3D%20%5Cdfrac%7B%5Csin%7BC%7D%7D%7Bc%7D%20)
In this case, we have an angle and two sides, and we are trying to look for the third side. First, we have to find the angle which corresponds with the second side,
. Then, we can find the third side. Using the law of sines, we can find:
![\dfrac{\sin{39^{\circ}}}{11} = \dfrac{\sin{B}}{13}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Csin%7B39%5E%7B%5Ccirc%7D%7D%7D%7B11%7D%20%3D%20%5Cdfrac%7B%5Csin%7BB%7D%7D%7B13%7D%20)
We can use this to solve for
:
![13 \cdot \dfrac{\sin{39^{\circ}}}{11} = \sin{B}](https://tex.z-dn.net/?f=%2013%20%5Ccdot%20%5Cdfrac%7B%5Csin%7B39%5E%7B%5Ccirc%7D%7D%7D%7B11%7D%20%3D%20%5Csin%7BB%7D%20)
![B = \sin^{-1}{\Big(13 \cdot \dfrac{\sin{39^{\circ}}}{11}\Big)} \approx 48.1](https://tex.z-dn.net/?f=%20B%20%3D%20%5Csin%5E%7B-1%7D%7B%5CBig%2813%20%5Ccdot%20%5Cdfrac%7B%5Csin%7B39%5E%7B%5Ccirc%7D%7D%7D%7B11%7D%5CBig%29%7D%20%5Capprox%2048.1%20)
Now, we can find
:
![C = 180^{\circ} - 48.1^{\circ} - 39^{\circ} = 92.9^{\circ}](https://tex.z-dn.net/?f=%20C%20%3D%20180%5E%7B%5Ccirc%7D%20-%2048.1%5E%7B%5Ccirc%7D%20-%2039%5E%7B%5Ccirc%7D%20%3D%2092.9%5E%7B%5Ccirc%7D%20)
Using this, we can find
:
![\dfrac{\sin{39^{\circ}}}{11} = \dfrac{\sin{92.9^{\circ}}}{c}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Csin%7B39%5E%7B%5Ccirc%7D%7D%7D%7B11%7D%20%3D%20%5Cdfrac%7B%5Csin%7B92.9%5E%7B%5Ccirc%7D%7D%7D%7Bc%7D%20)
![c = \dfrac{11\sin{92.9^{\circ}}}{\sin{39^{\circ}}} \approx \boxed{17.5}](https://tex.z-dn.net/?f=%20c%20%3D%20%5Cdfrac%7B11%5Csin%7B92.9%5E%7B%5Ccirc%7D%7D%7D%7B%5Csin%7B39%5E%7B%5Ccirc%7D%7D%7D%20%5Capprox%20%5Cboxed%7B17.5%7D%20)
c is approximately 17.5.
15/1 multiply by 4 to get the same denominator =
45/4 45 divided by 3 = 15 3/4 cups are needed which equals 45/4 cups of milk
Answer:
Brain
Step-by-step explanation:
Answer: x = 3
Step-by-step explanation:
Simplifying
17x + -3 = 48
Reorder the terms:
-3 + 17x = 48
Solving
-3 + 17x = 48
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 17x = 48 + 3
Combine like terms: -3 + 3 = 0
0 + 17x = 48 + 3
17x = 48 + 3
Combine like terms: 48 + 3 = 51
17x = 51
Divide each side by '17'.
x = 3
Simplifying
x = 3
