1 answer:

7 0

If you are looking for the sales tax then you take 89.75 times .075 this will give you 6.73 now you just add 6.73 to 89.75 and you get..

sales tax = $96.48

but if you are looking for the %off you are going to do 89.75 minus 6.73 and you will get....

%off= $83.02

A bag contains only red and blue marbles. There are a total of 36 marbles in the bag. There are 5 red marbles for every 4 blue m

Salsk061 [2.6K]

Answer:

let total no. of red marbles be x and blue marbles be y.

then according to first case

x + y =36

or,x=36 -y.....(i)

in case second

x/5 =y/4

or,x=5y/4......(ii)

then from equation i and ii, we get

36-y = 5y/4

or, (36-y)4 = 5y

or, 144 -4y =5y

or, 144 = 5y + 4y

or, 144 = 9y

or, 144/9 =y

or, y = 16

again x = 36 -y

here , y =16

so,

x= 36 -16

x= 20.

hence total no. of red marbles is 20 and blue marbles is 16 .

If Carls removes 1 blue marble from bag, there will be 15 marbles in the bag,

20÷5 is not equal to 15 ÷3 .

correct ratio of red and blue marbles is 20÷15=

4/3.

The points (5, 3), (3, -4), (10, 3), and (8, -4) are the vertices of a polygon. What type of polygon is formed by these points?

timofeeve [1]

Answer:

Parallelogram

Explanation:

Since there are four points, this is a quadrilateral.

There is a slope during the points. Therefore it could not be a rectangle nor square. The sides are still parallel though.

The length is not equal too, so it could not be a rhombus.

If you plot these points to the graph and connect them, it would form a parallelogram.

Find the indicated limit, if it exists. (2 points) limit of f of x as x approaches 5 where f of x equals 5 minus x when x is les

Tamiku [17]

It looks like we have

$f(x)=\begin{cases}5-x&\text{for }x5\end{cases}$

and we want to find $\lim\limits_{x\to5}f(x)$ .

Since $x$ is approaching 5, we don't care about the value of $f(x)$ when $x=5$ .

We do care about how $f(x)$ behaves to either side of $x=5$ . If $x\to5$ from below, then $f(x)=5-x$ , so that

$\displaystyle\lim_{x\to5^-}f(x)=\lim_{x\to5}(5-x)=5-5=0$

On the other hand, if $x\to5$ from above, then $f(x)=x+3$ , so that

$\displaystyle\lim_{x\to5^+}f(x)=\lim_{x\to5}(x+3)=5+3=8$

The one-sided limits do not match, since 0 ≠ 8, so the limit does not exist.

adoni [48]

Answer:

Independence and Exclusiveness are two topics which are important to probability and often confused. Discuss the difference between two events being independent and two events being mutually exclusive. Use examples to demonstrate the difference. Remember to explain as if you are talking to someone who knows nothing about the topic.

[my response: talk to them in formal language about the topic.]
