920,438. 921,438-1,000=920,438
B. One solution (I think)
Answer:
x times 3 equals y
Step-by-step explanation:
If it doesn’t provide the amount of students, it needs to be written as an equation. x will be the amount of students and y would be the amount of pencils each person gets. So, you need to multiply x with 3 because then it will show the result, which is y.
Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
32.68346376° = B
32.7° = B
