Answer: L = 1.27 radians.

Step-by-step explanation:

Here we have a triangle rectangle, for the triangle rectangle and one given angle θ we have the relations:

cos(θ) = (adjacent cathetus)/hypotenuse

sin(θ) = (opposite cathetus)/hypotenuse

tan(θ) = (opposite cathetus)/(adjacent cathetus)

Here we have the adjacent cathetus = 18in, and the hypotenuse = 60in.

Sowe can use the cosine relation:

Cos(L) = 18in/60in = 0.3

Acos(cos(L)) = L = Acos(0.3) = 1.266

We want to round it to the nearest hundredth, so we would have:

L = 1.27 radians.

Answer:

See below

Step-by-step explanation:

Part A

Formula

M = 2/3 * log(E/Eo)

Givens

M = ??

E = 2 * 10^15 joules

Eo = 10^4.4

Solution

M = (2/3) * log(2 * 10^15 / 10^4.4)

M = (2/3 ) log (7.96 * 10 ^ 11)

M = (2/3) * 11.901

M = 7.934

Part B

What the question is saying is that E/Eo = 10000

You don't have to figure out exact values.

M = 2/3 * log(10000)

M = 2/3 * 4

M = 8/3 or 2 2/3 or 2.66667

If you have choices, please list them.

Please help!!! I’ll mark brainliest!!

nalin [4]

Answer:

9:50

Step-by-step explanation:

To get the ratio, we can just simplify a fraction down to 1.

Since there's 18 dimes, and 100 coins in total, we'll start with the fraction

18/100

Put 18/100 in simplest form

9/50

Then Turn the fraction into a ratio

9/50 -> 9:50

For every 9 dimes there's 50 coins.

I hope this helped.

(Simplified to 1, is 1/5.56 or 1:5.56)
