Explain why you must simplify 3 to the second power first

Answers

Because you have to go in the order of PEMDAS, parenthesis, exponents, multiplication, division, addition, and subtraction. From what you are saying, 'why you must simplify 3 to the second power first' it seems that you have no parenthesis, so you move onto what is next, which is exponents, in this case, 3 to the power of two.

A state lottery commission analyzes the ticket purchasing patterns of its citizens. The following expression is developed to help officials calculate the likely number of people who will buy tickets for a certain size jackpot. 81a^2-36b^2
Factor the expression completely.

Answers

So,

We first factor out the GCF.

$9(9a^2-4b^2)$

Now, we notice that the expression is a difference of two perfect squares.
$9(3a+2b)(3a-2b)$

The expression is now factored completely.

9(9a^2-4)

9(3a+2)(3a-2)

I hope this helps!

A typical stone on the lowest level of the great pyramid in Egypt was a rectangular prism 5 feet long by 5 feet high by 6 feet deep and weighed 15 tons. what was the volume of the average stone? How much did one cubic foot of this stone weigh?

Answers

Which expression is equivalent to sin7pi/6?A. sinpi/6
B. sin5pi/6
C. sin5pi/3
D. sin11pi/6

Answers

For this case we must find an expression equivalent to:

$Sin (\frac {7 \pi} {6})$

According to the unit circle, $\frac {7 \pi} {6}$ is in the third quadrant and equals 210 degrees.

Then, we must find an expression equivalent to:

$Sin (210) = - \frac {1} {2} = - 0.5$

We have to:

$\frac{11 \pi} {6}$

It is in the fourth quadrant and is equivalent to 330 degrees, according to the unit circle.

$Sin (330) = - \frac {1} {2} = - 0.5$

Answer:

Option D

The answer choice is D because sin7pi/6 which it’s exact form is -1/2 the only answer choice which the same exact form is D.

How many times does 8 go into 50

Answers

$\frac { 50 }{ 8 } \n \n =\frac { 25 }{ 4 } \cdot \frac { 2 }{ 2 } \n \n =\frac { 25 }{ 4 } \cdot 1$

$\n \n =\frac { 25 }{ 4 } \n \n =\frac { 24 }{ 4 } +\frac { 1 }{ 4 } \n \n =6+\frac { 1 }{ 4 }$

8 goes into 50 six times, with a remainder of 2, On dividing 50 by 8 quotient is 6 and remainder is 2

To find out how many times 8 goes into 50, we perform integer division.

When we divide 50 by 8, we obtain a quotient and a remainder. The quotient represents the whole number of times 8 can be divided into 50 without any remainder.

The remainder represents any leftover amount after dividing as much as possible.

Performing the division:

50 ÷ 8 = 6 remainder 2

Therefore, 8 goes into 50 six times, with a remainder of 2, On dividing 50 by 8 quotient is 6 and remainder is 2
