The correct answer is 6 × (7 + 2) - 1 = 53. This is because in the Order of Operations, multiplying comes first. So to make sure you get the right answer, you have to put the 7 + 2 in parentheses to get 6 × 9 - 1 and not 6 × 7 + 1.

Answer:
(b) tan B = 8/6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Then angle B is involved in tangent and cosine relationships this way:
tan B = 8/6 . . . . . . matches 2nd choice
cos B = 6/10 . . . . . matches no choices
_____
<em>Additional comment</em>
Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.

Answer: 50
Step-by-step explanation: 1/4 = 50
2/4 = 100
3/4 = 150
4/4 = 200
Answer: 0.77
Step-by-step explanation:
Given : Probability that a student chooses a turkey sandwich is
P(Turkey )= 0.10
Probability that a student chooses an egg salad sandwich is
P(egg salad)=0.67
Also, it is impossible for a student have both lunches.
∴ P(Turkey and egg salad) =0
Now , the probability that a student chooses a turkey or egg salad sandwich will be
P(Turkey or egg salad) = P(Turkey )+ P(egg salad)- P(Turkey and egg salad)
= 0.10+ 0.67-0 = 0.77
Hence, the probability that a student chooses a turkey or egg salad sandwich= 0.77
