37) (2^-3) = 1/2³= ⅛.
38) ½^-3=1/½^3=1/⅛=8
Two ten packs is 5.49 and two 4 pack 2.98
10 batteries is 5.49 and 8 are 2.98
if the question is which is the better deal i would say the buy one get one free
Answer: 4 out of 13
Step-by-step explanation:
Total letters in "MASSACHUSSETT " = 13
Number of S = 4
Probability of an event = 
The probability of selecting the letter S =
[already in lowest term as gcd(4,13)=1]
Hence, the probability of selecting the letter S = 4 out of 13.
Answer:
684/1525
Step-by-step explanation:
Given
cosA = 24/25
SinB = 11/61
Sin(A+B) = SinAcosB + CosAsinB
Get SinA
Since
Cos A = adj/hyp
adj = 24
hyp = 25
opp² = 25² - 24²
opp² = 625 - 576
opp² = 49
opp = √49
opp = 7
sinA = opp/hyp
sinA = 7/25
Also if SinB = 11/61
opposite = 11
Hypotenuse = 61
adj² = 61² - 11²
adj² = 3,721 - 121
adj² = 3600
adj = √3600
adj = 60
Cos B = adj/hyp
CosB = 60/61
Sin(A+B) = SinAcosB + CosAsinB
Sin(A+B) = 7/25(60/61) + 24/25(11/61)
Sin(A+B) = 420/1,525 + 264/1,525
Sin(A+B) = 684/1525
