Help me please this is due in like 30 mnutes

Sin(30) = 1/2;

Cos(30) = sqrt(3)/2

Tan(60) = sqrt(3)

Step-by-step explanation:

Sin(30) = opposite/hypotenuse

Sin(30) = 7/14 = 1/2

Cos(30) = adjacent/hypotenuse

Cos(30) = 7sqrt(3)/14 = root(3)/2

sqrt: square root

Tan(60) = opposite/adjacent

Tan(60) = 7sqrt(3)/7 = sqrt(3)

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
