Hope I Helped You!!! :-)

Have A Good Day!!!

Answer 2

Answer:

Answer:

1.09

Step-by-step explanation:

"Percent" means "per 100" or "over 100". To convert 109% to a decimal rewrite 109 percent in terms of per 100 or over 100.

109% = 109 over 100 or,

109%=109100109 over 100 is the same as 109 divided by 100. Completing the division we get:

109 ÷ 100 = 1.09

Therefore, we have shown that

109% = 1.09

Simplified Conversion:Remove the percent sign % and divide by 100.

109 ÷ 100 = 1.09

Shortcut Conversion:Move the decimal point 2 places to the left and remove the percent sign %

109% becomes 1.09

Destiny works on commission as an office supply saleswoman. She sold a computer that cost $700 and received a $126 commission. What percent of her sale is Destiny's commission?

Answers

To figure out the answer to this problem, you must first ask yourself this:

How much is 126 of 700
or
What is 126 divded by 700

The answer is 0.18.

So, that means that 0.18 or 18 percent might be your answer.

Now, lets try 18 percent of 700, to see if we get 126.

18% times 700

The anwer is 126.

SO:

$126 is 18 percent of 700.

18 percent of her sale is Destiny's commission.

There are 6 times as many dogs as cats. If the total number of dogs and cats is 21. How many dogs are there? Show your work

Answers

there are 3 cats and 18 dogs. :D

I say divide 21 with 6 and you get 3.5 so round it and you get 3.Then subtract 3 from 21, so the answer is 3 cats ad 18 dogs.

hope this helps :)

Answer:

13 cartons

Step-by-step explanation:

75 divided by 6 is 12 R 3.

You have to round up the quotient, so the answer is 13 because you have to ship leftover footballs too.

What is 2x times x squared?

Answers

We want to multiply the monomial $2x$ by the monomial $2x^2$ .

Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: $(a^m)(a^n)=a^(m+n)$ , $(x^2)(x^4)=x^(2+4)=x^6$ . Also, is worth pointing out that the exponent of a variable with no exponent is 1: $x=x^1$ .

Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so $x=1x$ . Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.

Let's apply all of that to our multiplication:

$(2x)(x^2)=(2x^1)(1x^2)=2*1x^(1+2)=2x^3$

We can conclude that 2x times x squared is 2x cubed.

$2x$ times $x$ is $\boxed{\bf 2x^(3)}$ .

Further explanation:

A monomial is an expression which contains one term and a monomial includes numbers and variables which are multiplied together. The constant term is multiplies with an another constsnt term and the variable is multiplies with an another variable term.

Law of exponent:

Product with same base: If we multiply the same bases with different exponents then the base remains the same and the exponents are added in the final product.

Calculation:

Now, we are given the two monomials as $2x$ and $x^(2)$ .

Multiplying both the monomials as follows:

$\boxed{2x\cdot x^(2)}$

Here, $x$ is a variable and $x$ has power $1$ in the first monomial and $x$ has power $2$ in the second monomial.

Using the mentioned law of exponents as the variable $x$ is similar in both the monomial and add the powers of both as follows:

$\boxed{\begin{aligned}2x\cdot x^(2)&=2x^(1+2)\n&=2x^(3)\end{aligned}}$

Therefore, $2x$ times $x$ is $\boxed{\bf 2x^(3)}$ .
