Choose the correct simplification of the expression a to the 7th power times b to the 8th power all over a to the 4th power time

defon

First you need to write the numerical equation for the given:

$\frac{ a^{7} b^{8} }{ a^{4} b^{4} }$

When you will simplify this fraction, you can divide the expressions. Based on the law of exponents when you divide like terms with different exponents, you can subtract the exponents of the denominator from the numerator.

So if you will simplify the equation:

$\frac{ a^{7} b^{8} }{ a^{4} b^{4} }$

Subtract the following:

Exponents of a 7-4 and;
Exponents of b 8-4

Your answer should be
$a^{3} b^{4}$

Tyra has 12 2/3 cups of sugar. If r is the amount of sugar called for in one batch of cookies, the expression 12 2/3 ÷ r can be

joja [24]

Answer:

19 batches

Step-by-step explanation:

Given that:

Total number of cups of sugar = $12\frac{2}{3}$

Amount of sugar used in one batch = $r$

Number of batches that can be made by Tyra with the amount of sugar that is available with Tyra can be calculated by dividing the total number of cups of sugar available with Tyra with the amount of sugar to be used in one batch.

i.e.

Number of batches = $12\frac{2}{3} \div r$

Also, if we put the value:

$r=\frac{2}{3}$

We have to find the number of batches of cookies that can be made by Tyra.

Solution:

First of all, let us have a look at the formula to convert the mixed fraction into fractional number.

$a\dfrac{b}{c} = \dfrac{a\times c + b}{c}$

Therefore,

$12\dfrac{2}{3} = \dfrac{12\times 3 + 2}{3} = \dfrac{38}{3}$

Number of batches:

$\dfrac{38}{3} \div \dfrac{2}{3}\\\Rightarrow \dfrac{38}{3} \times \dfrac{3}{2}\\\Rightarrow \bold{19}$

Therefore, 19 batches can be completed.

The meaning of the slope is retained in the case of; "as the time spent swimming increases, the number of calories burnt increases".

<h3>What is a slope?</h3>

The slope of a graph describes how steep the graph is. It can be used to show the relationship between variables.

If we interchange the positions of the dependent and the independent variables, the meaning of the slope is retained in the case of; "as the time spent swimming increases, the number of calories burnt increases".
