How can knowing the multiplication properties help you multiply 5x(2x6)?

Answers

PEMDAS helps because it tells you that the first thing to do it the P= parenthesis, so first you would do 2x6 which is 12 then you would have 5(12) the only other property to do would be M=multiplation so then solve 5x12

Time measured in minutes is an example of a(n) _______________ scale.

Answers

The answer is interval scale.

The answer can be written in statement form as,"Time measured in minutes is an example of a(n) interval scale."

What is an interval scale?

A numerical scale known as an interval scale is one in which both the order of the variables and their differences are known. Using the Interval scale, variables with recognizable, consistent, and calculable differences are categorized.

It is easy to remember the primary role of this scale too, ‘Interval’ indicates ‘distance between two entities’, which is what Interval scale helps in achieving.

The value of time is given in minutes.

The given quantity can be measured on interval scale.

Hence, the required scale is known as interval scale.

Any proposed solution of a rational equation that causes a denominator to equal _______ is rejected.

Answers

Answer:

Any proposed solution of a rational equation that causes a denominator to equal __ZERO__ is rejected.

Step-by-step explanation:

We will show this statement is true by an example:

Consider the expression : [tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

Now, solved the rational expression and check its proposed solution

[tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

x cannot equal to 4, as it makes both denominators equal to zero.

Multiply both the sides by (x-4),

[tex]\left ( x-4 \right )\cdot \frac{x}{x-4}=\left (x-4 \right )\cdot\left ( \frac{x}{x-4}+4 \right )\\[/tex]

Now, use the distributive property on Right hand side,

[tex]\left ( x-4 \right )\cdot \frac{x}{x-4}=\left (x-4 \right )\cdot \left ( \frac{x}{x-4} \right )+\left (x-4 \right )\cdot 4\\[/tex]

Simplify the above expression,

[tex]x=x+4x-16[/tex]

Combine like terms,

[tex]x-x-4x=-16[/tex]

[tex]-4x=-16[/tex]

Divide both sides by -4, we get

[tex]\frac{-4x}{-4}=\frac{-16}{-4}[/tex]

[tex]x=4[/tex].

As we know that x cannot equal to 4, replacing x=4 in the original expression causes the denominator equal to 0.

Check the solution: [tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

Substitute the value of x=4 in the original expression,

[tex]\frac{4}{4-4}=\frac{4}{4-4}+4[/tex]

[tex]\frac{4}{0}=\frac{4}{0}+4[/tex]

Thus, 4 must be rejected as the solution, and the solution set is only 0.

Final answer:

A proposed solution of a rational equation that causes a denominator to equal zero is rejected because division by zero is not possible.

Explanation:

Any proposed solution of a rational equation that causes a denominator to equal zero is rejected. When the denominator of a rational equation is zero, the fraction becomes undefined because division by zero is not possible. In mathematics, division by zero is an undefined operation.

what is 150% as a fraction

Answers

150% means 150 out of 100 so find the GCF of both 150 and 100 and that would be 50 since it can go into both 150 and 100.

divide both the numerator and denominator by GCF

Simplify

Answer: 3/2

To write .150 as a fraction you have to write .150 as the numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.150 = .150/1 = 1.5/10 = 15/100

And finally we have:
.150 as a fraction equals 15/100

In October Greg and Thomas had the same amount of money in their savings account in November Greg deposited $120 into his account Thomas increased the money in his account by 20% when they compare their bounces they found out they were still equal

Answers

assume the amount of money they both deposited in october is m.
in november, greg deposited 120$, so the total amount in his account became m+120
thomas increased his account by 20%, this meams that the amount of money in his account became: m+0.2m
since both values are still equal, we will equate the two equations and solve for m:
m+120 = m+0.2m
0.2m = 120
m = 600$
