Answer: SOHCAHTOA
Step-by-step explanation:
The pneumonic I learned is SOH-CAH-TOA. it says that Sin = opposite/hypotenuse. Cos = adjacent/hypotenuse. Tan = opposite/adjacent.

Answer:
40
Step-by-step explanation:
8×(40+7)=(8×__)+(8×7)
several ways to do this, but the most simplistic (but probably not the quickest) way to do it is to simplify both sides of the equation and solve for the missing number,
lets substitute n for the missing number, hence equation becomes:
8×(40+7)=(8×n)+(8×7) (by PEDMAS, evaluate terms inside parentheses first)
8 x (47) = (8n) + (56)
8 x 47 = 8n + 56 (next evaluate multiply)
376 = 8n + 56 (subtract 56 from both sides)
376 - 56 = 8n (evaluate subtration and rearrange)
8n = 320 (divide both sides by 8)
n = 320 / 8
n = 40
The probability the first marble will be blue is 28/40
The probability the second marble will be red is 12/39
The reason is because 28 + 12 = 40, so this makes the denominator for our first outcome, but then a marble is removed making our denominator 39 because 40-1 = 39.
