12% error. To find out subtract the difference between the estimate and the actual amount sold and divide the difference by the estamite.

Give an example of this when adding two rationalnumbers with different signs and provide the product.

kolezko [41]

ANSWER:

$\begin{gathered} \frac{4}{5}+-\frac{8}{3}=-\frac{28}{15} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{32}{15} \end{gathered}$

STEP-BY-STEP EXPLANATION:

Rational numbers are all numbers that can be expressed as a fraction, that is, as the quotient of two whole numbers.

Therefore, an example would be:

$\begin{gathered} \frac{4}{5}\text{ and - }\frac{8}{3} \\ \text{adding} \\ \frac{4}{5}+-\frac{8}{3}=\frac{4}{5}-\frac{8}{3} \\ \frac{4}{5}-\frac{8}{3}=\frac{4\cdot3-5\cdot8}{5\cdot3}=\frac{12-40}{15}=-\frac{28}{15} \\ \text{ product} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{4\cdot8}{5\cdot3}=-\frac{32}{15} \end{gathered}$

I need help and steps of how u got it

Gnom [1K]

Answer:

A) 4

Step-by-step explanation:

There are a couple of ways to get this but this is how I did it:

1. Multiply the second equation by 1/4 to get the same fraction for y as the one in the first equation

1/4 x + 1/8 y = 2

1/4 (1/3 x + 1/2 y = 4)

1/12 x + 1/8 y = 1

2. Subtract the first equation from the new equation

1/12 x + 1/8 y = 1

<u> - 1/4 x - 1/8 y = -2</u>

-1/6 x= -1

3. Divide both sides by -1/6

<u>-1/6</u> x= <u>-1</u>

-1/6 -1/6

x = 6

4. Substitute 4 in for x in the original equation:

1/4 (6) + 1/8y = 2

6/4 + 1/8y = 2

1/8y = 1/2

y = 4

The altitude above sea level of an airplane just after taking off from an airport on a high plateau is given by the linear funct

Zolol [24]

Answer:

Slope, m = 1100

y-intercept,c = 2491

Step-by-step explanation:

We are given the following in the question:

$y(x) = 1100x + 2491$

The above gives the altitude of the airplane above the sea level in feet(y) after x minutes since the take off.

Comparing the above equation, to a general linear equation, we have,

$y = mx + c$

where m is the slope and c is the y-intercept.

Comparing we get,

Slope, m = 1100

y-intercept,c = 2491

Interpretation:

The slope of equation tells us about the rate of change of function with unit increase in value of x. Thus, the altitude of airplane increases 1100 feet when the time increases by 1 minute.
The y-intercept is the value of y when x is 0. Thus, the altitude of airplane is 2491 feet when the airplane has not taken off.

Martha estimated the quotient of -71.81 and -8.02 using

steposvetlana [31]

Option 2

Martha estimated the quotient. Martha error was she should have rounded -8.02 to -8.

<u>SOLUTION: </u>

Given that, Martha estimated the quotient of -71.81 and -8.02 using rounding to the nearest whole number.

And she committed an mistake. We have to find the error made by Martha while calculating quotient.

She treated -71.81 to be 72 and -8.02 to be 9. As both the number are negative there will be no problem when we get quotient.

When treated as above she got quotient as 8.

But in general, the quotient is not 8.

If we see options, we derive an conclusion.

<u>Option (1) </u>

she should have rounded 71.81 to 70, no this is not correct as 72 is nearest whole number.

<u>Option (2)</u>

she should have rounded 8.02 to 8, yes this is correct conclusion.

<u>Option (3)</u>

she should have divided 8 by 72, no this is not correct, we should divided 72 by 8.

<u>Option (4) </u>

she didn’t make an error, this is wrong as in 2nd option we caught an error.

Hence, second option is correct.
