Answer:

<em>The quotient is $\frac{7}{12c}$ </em>

Step-by-step explanation:

Given expression is: $\frac{5}{4c^2}\div \frac{15}{7c}$

<em>While dividing two fractions, first we need to change the division sign into multiplication and then flip the second fraction. </em>

So, we will get.....

$\frac{5}{4c^2}\div \frac{15}{7c}\\ \\ =\frac{5}{4c^2}\times \frac{7c}{15}\\ \\ =\frac{35c}{60c^2}\\ \\ = \frac{7}{12c} \ \ [Dividing\ both\ numerator\ and\ denominator\ by\ 5c]$

So, the quotient is $\frac{7}{12c}$

Melinda works at a cafe. Each day that she works, she records x, the total dollar amount of her customers’ bills and then y, her

Anna35 [415]

Answer:

$26

Step-by-step explanation:

In the picture attached, the table, the plot and the line of best fit are shown. There we can see the next equation:

y = 0.177x + 25.936

where x is the total dollar amount of her customers’ bills and then y is her total daily wages.

This means that even if she serves no customers (x = 0) she will earn $26 ($25.936 rounded to the nearest dollar) for each day of work.

Help me with Alims sales tax problem

wlad13 [49]

First you need to find the amount for each of the items, then total it up:

T-shirts> 9.50 x 2 = 19
Socks> 7.95 x 3 = 23.85
Shoes> 49.95
Total: 19 + 23.85 + 49.95 = $92.80

Next find the tax:

(to find the taxes you multiply the total by the percent)
92.8 x 0.06 = 5.57
-- then add the amount to your item total
92.8 + 5.57 = 98.37

~OR~

You could multiply the item total by 1.06 so that you wouldn't have to add to taxes to the previous total because it is already part of the equation

92.8 x 1.06 = 98.37

In right triangle ABC, mC - 90° and AC BC. Which trigonometric ratio is cquivalent to sin b?

vaieri [72.5K]

Answer:

All trigonometric Ratios are $SinB = \frac{AC}{AB}$ , $SinA= \frac{CB}{AB}$ , $CosA= \frac{AC}{AB}$

And $Cos B = \frac{CB}{AB}$ .

Step-by-step explanation:

Given that,

A right angle triangle ΔABC, ∠C =90°.

Diagram of the given scenario shown below,

In triangle ΔABC :-

$Hypotenuse = AB\\Base = CB\\Perpendicular = AC$

So, $Sin\theta = \frac{perpendicular}{hypotenuse}$

$SinB = \frac{AC}{AB}$

Now, for ∠A the dimensions of trigonometric ratios will be changed.

Here the base for ∠A is AC , perpendicular side is CB and hypotenuse will be same for all ratios.

$SinA= \frac{CB}{AB}$

Again, $Cos\theta= \frac{base}{hypotenuse}$

Then, $CosA= \frac{AC}{AB}$

And $Cos B = \frac{CB}{AB}$ .

Hence,

All trigonometric Ratios are $SinB = \frac{AC}{AB}$ , $SinA= \frac{CB}{AB}$ , $CosA= \frac{AC}{AB}$

And $Cos B = \frac{CB}{AB}$ .

OleMash [197]

Answer: Isaac will be able to drink 2920 glasses of water in a year if he drinks 8 glasses of water each day.

Step-by-step explanation:

365 • 8 = 2920

2920 ÷ 365 = 8

2920 ÷ 8 = 365

In the figure, the slope of mid-segment DE is -0.4. The slope of segment AC is . i need help fast plz

AlexFokin [52]

It will have the same value. The slope of the mid-segment of DE is just equal to the slope of the segment of AC. This is because of the mid-segment theorem stating that both slopes of a triangle have same value. So the answer is -0.4 for both segments.
