The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
Since he has to give 50, and 12.25*p is the amount of money he has to spend (since it's 12.25 per pizza), we have 50-12.25=change
Answer: 72 cm²
Step-by-step explanation: 1/2(base)(height) is the formula to find the area of a triangle. To find the area of the bigger triangle we substitute 10 cm for the base and 6 cm for the height.
1/2(10)(6)
1/2(60)
30 cm²
since we have two of the same triangles, we double that
we also have a smaller triangle. 14-10=4 which is the base of the smaller triangle.
1/2(4)(6)
1/2(24)
12 cm²
now, we add everything
60 cm² + 12 cm² = 72 cm²
Answer:
150 in. squared
Step-by-step explanation:
She needs more then 472 and has 296 so she still needs 176 because 472-296=176
Each bracelets is 4 so then 176/4 is 44
1. She needs to sell 44 more bracelets,45 if she needs more than 472
2 the inequality would be x>=44 bracelets
