Yes, you are correct.

SOH CAH TOA can be a good mnemonic aid for remembering trigonometric funtions.

11^5=161051?

Start off by subtracting both sides by 3x; 2x-3+21.

Add 3 to isolate the 2x; 2x=24.

Divide by 2, and x=12.

16 ounces in 1 pound, 16 times 20 would be the number of ounces in 20 pounds.

First, let's find out the diameter by dividing the area by pi.

175.84/3.14 is 56.

The formula for the area of a circle is pi*(radius^2).

The diameter is twice the length of the radius. 56/2=28.

28 squared times 3.14 is 2461.76.

Yes, your answer is correct.

4[300-5]-[84-(8-6)]

4(295)-[84-2]

1180-82=1098

2y, subtracting a negative number is like adding the opposite of the negative number.

60 times 42% is 25.2, but since there can't be a decimal number of people, the answer is 25 people.

When squaring a fraction, you can square the numerator and the denominator, and put the squares as a new fraction. (Square of numerator is the numerator, and you can guess where the denominator is.)

5 squared is 25, 3 squared is 9.

5/3 squared is 25/9.

Just combine like terms, and you get 12x-9.
