Answer:

sin(theta) = 0.5

tan(theta) = -0.577

Step-by-step explanation:

Cos theta = -0.866

Theta = 2.617943073

(Because in the second quadrant)

sin(theta) = 0.5

tan(theta) = -0.577

What part of 5 and 3/4 is 7/10?
Effectus [21]

Answer:

7/10 is approximately 12.17% of 5 3/4.

To solve this, you'd first convert each value into a decimal.

7/10 - 0.70

5 3/4 - 5.75

Look at each value as a whole number. For example, if you wanted to find 3 of 8, you'd solve 3/8. The same principle applies here. If you were to type this into your calculator, you'd get 0.12173913043.

Next, convert the decimal (your quotient) into a percentage.

Remember, to convert a decimal to a percent, you have to multiply it by one hundred. So, .12173913043 would be 12.173913043.

After you convert, you can round to the nearest hundredth- that would give you 12.17%.

Check your answer:

To do this, you could multiply 5.75 by 12.17%, which would give you 6.99775.

You could then take this value and round it to 7.

Hope this helps,

You are playing a board game with a spinner that has numbers 1, 2, 3, and 4 on
Whitepunk [10]

Answer:

1/4

Step-by-step explanation:

Let x = number the spinner lands on

P(X = 1) = 1/4

P(X = 2) = 1/4

P(X = 3) = 1/4

P(X = 4) = 1/4

The spins are independent events as their probabilities are not affected by whether or not the other event happens

Therefore, the probability that you land on a number 2 given that your first spin landed on number 1 is still 1/4

Hello there! The formula for finding simple interest is prt. That means multiply the principal (initial amount) by the rate (simple interest percentage) by the amount of time (could be in months or years). In this case, $9800 is the initial amount in the bank and the interest rate is 2% for 15 years. Let’s multiply the numbers. 9800 * 2% (0.02) is 196. That’s $196 a year in simple interest. But it asks for the amount in 15 years, so we multiply those two numbers. 196 * 15 is 2,940. There. $2,940 is earned in interest over 15 years. The answer is A: $2,940.
