Answer:
70
Step-by-step explanation:
100 shots is ten times the amount she took first
so we do 7 × 10 =70
Answer: x = - 111
Step-by-step explanation:
- Add the like terms on the right side of the equation. 45 + 85 = 130. 130 - 180 = - 50. The equation simplifies to x + 61 = - 50
- Subtract 61 on both sides. x = - 111
Answer:
4
Step-by-step explanation:
x^0 means 1. so 1+3=4
Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
