Step-by-step explanation:
Answer:
13 months
Step-by-step explanation:
1105 divided by 85 is 13
Square both given expressions and add them together. Make use of trig identities.
(sin(a) +sin(b))^2 = sin(a)^2 +2sin(a)sin(b) +sin(b)^2 = 5/3
(cos(a) +cos(b))^2 = cos(a)^2 +2cos(a)cos(b) +cos(b)^2 = 1
Adding, we have
sin(a)^2 +cos(a^2) +2(cos(a)cos(b) +sin(a)sin(b)) +sin(b)^2 +cos(b)^2 = 2 2/3
Of course, the first and last pairs of terms are 1 and 1, and the middle product is 2cos(a-b), so you have
1 + 2cos(a-b) +1 = 2 2/3
cos(a-b) = 1/3
Answer:
15/16 (93.75%)
Step-by-step explanation:
List of Possible Combinations:
BBBB, BBBG, BBGB, BBGG, BGBB, BGBG, BGGB, BGGG, GBBB, GBBG, GBGB, GBGG, GGBB, GGBG, GGGB, GGGG
As you can see, only 1 out of 16 of the possible combinations is all boys. This means that the chance of at least 1 girl among the 4 children is 15 out of 16 (15/16) or 93.75%
Answer:
11.31 $
Step-by-step explanation:
Given in question that
total apple brought to make candy apples = 5 pounds 7 ounce
since 1 pound = 16 ounce
so, 5 pounds = 5 x 16 = 80 ounces
therefore total apple brought = 80 + 7 =87 ounces
again,
cost of 1 ounce = 13 cents
so, cost of 87 ounces = 13 x 87 = 1131 cents
now,
we know that 1 cent = 0.01 dollar
so, 1131 cents = 0.01 x 1131 = 11.31 $
