Answer:

57.606184 kilograms

Step-by-step explanation:

Given :An adolescent has a weight of 127 pounds.

To Find : Convert 127 pounds to kilograms.

Solution :

Weight of adolescent = 127 pounds

We are supposed to find the weight in kilograms.

1 pound = 0.453592 kilograms

127 pounds = 0.453592 \times 127 kilograms

127 pounds = 57.606184 kilograms

Hence 127 pounds in kilograms is 57.606184 kilograms

C-3d = 11<br> -2c + 3d = -16
disa [49]

This looks like a system of equations:

We should solve for c on the first equation because we can substitute for c. There are a lot of ways we can do a system of equations, but I will do this.

c - 3d = 11

  +3d     +3d

c = 11 +3d

Now we can substitute.

-2(11+3d) + 3d = -16

solve

-22 + -6d + 3d = -16

-22 + -3d = -16

+22             +22

-3d = 6

/-3     /-3

d = -2

So we have found d. We can solve for c.

c - 3(-2) = 11

c + 6 = 11

  -6      -6

c = 5

Now we know both D and C. d=-2 and c=5

Find the cosine of angle B.
Alexandra [31]

\boxed { \text {Cosine Rule : } a^2 = b^2 + c^2 - 2bc \cos(A) }

-

9² = 12² + 15² - 2 (12) (15) cos (B)

81 = 144 + 225 - 360 cos(B)

81 = 369 - 360 cos (B)

360 cos (B) = 369 - 81

360 cos (B) = 288

cos (B) = 0.8

-

Answer: Cosine B = 0.8

-

\boxed { \text {Cosine Rule : } a^2 = b^2 + c^2 - 2bc \cos(A) }

-

12² = 15² + 9² - 2 (15)(9) cos (A)

144 = 225 + 81 - 270 Cos A

144 = 306 - 270 Cos A

270 Cos A = 162

Cos A = 3/5 or 0.6

-

Answer: Cosine Angle A = 3/5

Just 2 questions i need help with :)) thanks!!
Mila [183]

Answer:

I'm not so sure on these answers

1) 60 combinations

2) 90 or 60 combinations

Step-by-step explanation:

When doing these types of questions, use the Fundamental Counting Principle (you could also use a tree diagram which lists every possible combination individually for each item)

Basically for Fundamental Counting Principle, you multiply the amounts.

Ex: 5 jeans x 4 T-Shirts = 20             5 x 4 x 3 = 60!

     20 x 3 pairs of shoes= 60          

I wasn't sure if I had to include the right, left, right as 2 or 3.
