Answer:

90. 04987916

Step-by-step explanation:

Let HI be a

and GH be c

and GI be b

and <GHI be B

Using the law of Cosines,

b^2= -2ac cos (B) + c^2 + a^2

= -2(42)(60) cos (123)+60^2+42^2

= -5040 cos (123) +3600+1764

= -5040(-0. 544639035) +5364

= 2744. 980736+5364

b^2= 8108. 980736

b= Sqrt ( 8108. 980736)

b= 90. 04987916

Answer:

The answer is 99.2

Step-by-step explanation:

The law of cosine states that...

c^2=a^2-2*a*b*cos(theta)

c^2=42^2+60^2-2(42)(60)cos(123)

c^2=1764+3600+4475.36

c=sqrt of 9839.36

c=99.2

The New York Queens Zoo celebrated the birth of a Southern pudu deer in July of 2013. The doe is a member of the world’s smalles
PolarNik [594]

The pudu weighed approximately 1 pound at birth.

Given that the New York Queens Zoo celebrated the birth of a Southern pudu deer in July of 2013 which tipped the scale of a mere 0.45 kg, to determine, given that one kilogram is approximately equal to 2.2 pounds, about how many pounds did the pudu weigh at birth, the following calculation must be performed:

  • 1 = 2.2
  • 0.45 = X
  • 0.45 x 2.2 = X
  • 0.99 = X

Therefore, the pudu weighed approximately 1 pound at birth.

Torrey has $20 to buy a birthday present for her that she does this to buy a CD for $18 the sales tax is 7% does she have enough
Effectus [21]
No, because she will go over by .57 cents. So she won't be able to buy the gift. You can find the answer by dividing 18 by 7 and adding that answer to 18 to get the amount total you owe including tax.

Suppose you choose a marble from a bag containing 3 red marbles. 3 white marbles, and 5 blue marbles. You return the first marbl
Flauer [41]

Answer:

15/121.

Step-by-step explanation:

Probability of picking a red = number of reds in the bag / total number of marbles in the bag

= 3 / (3 + 3 + 5)

= 3/11.

Probability of picking a blue = 5/11.

These 2 events are independent so we multiply probabilities, therefore the

Probability of (a red then a blue) = 3/11 * 5 /11

= 15/121.
