Answers

Answer:

28.91×10^48

hope it helps.

Because they both have the same exponent, just add the numbers together:

5.9 + 4.9 = 10.8

So now you have:

5.9 x 10^24 + 4.9 x 10^24 = 10.8 x 10^24

A scientific number can only have 1 number to the left of the decimal, so you need to move the decimal one place to the left. When you move the decimal to the left you add to the exponent.

The answer is: 1.08 x 10^25

Answers

Answer: The radius is 12.54 feet, and the diameter is 25.08 feet.

Explanation: By applying the circumference into the equation r = [tex]\frac{C}{2\pi }[/tex], we get r = [tex]\frac{78.8}{2\pi }[/tex]which simplifies the radius. And since radius is half of diameter, we multiply by 2 to get the diameter as well to solve the other blank in the problem.

The angle of depression between the top of a 100-foot cliff and a ship approaching the shore is 37. What is the approximate distance, d, between the bottom of the cliff and the ship?

Answers

Answer:

76 feet

Step-by-step explanation:

let 'd' = distance from bottom of cliff and ship

sin 37 = sin 53

    d           100

0.61 = 0.8

  d         100

cross-multiply:    61 = .8d

                            d = 76

I assumed the bottom of the cliff and the shore formed a 90 degree angle - which leaves the 37° angle and a 53° angle

Answers

Answer:

A. m<R, m<S, m<Q

Step-by-step explanation:

In a triangle, the length of each side determines the size of the angle opposite it. Thus, the longer the side, the bigger the size of the angle opposite it. The shorter the side, the smaller the size of the angle opposite it.

In ∆QRS, we have the following:

✔️The longest side is RS = 16. <Q is opposite to RS, therefore <Q is the largest angle.

✔️The medium side is QR = 15. <S is opposite to QR, therefore <S is the medium angle.

✔️The shortest side is SQ = 9. <R is opposite to SQ, therefore <R is the smallest angle.

From smallest to the largest we would have:

m<R, m<S, m<Q
