Answer 1
Answer:

Answer:

D. A\subset \mathbb{R}*\mathbb{R}.

Step-by-step explanation:

Consider the set

A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}

This set consists of four ordered pairs.

The first numbers in these pairs are 2,\ 5,\ -3,\ 0. These numbers are integer numbers (not natural, because -3 is negative).

The second numbers in these pairs are 3,\ 1,\ -2,\ 3. These numbers are integer numbers too (not natural, because -2 is negative).

Options contain only natural and real sets, so, the first and the second numbers are real numbers and

A\subset \mathbb{R}*\mathbb{R}.

Answer 2
Answer:

Answer:

D. R X R

Step-by-step explanation:

The answer is choice D because, the set of the actual numbers of R has a 0 so A is a subset of R X R

Keri is making a doll clothes for a holiday craft show. The wholesale cost of the materials for one outfit is $9.38. If she sells an outfit for $15, what is the nearest percent?

Answers

Answer:

60%

Step-by-step explanation:

If I get you right, you're asking for the percentage gain to the nearest percentage, right?

Now to do this, we need to get the amount of profit she made. That's quite easy, we only need to subtract the cost price from the selling price. And that equals $15 - $9.38 that equals $5.62.

Now, we divide this value by the cost price and multiply by 100% to get the percentage gain.

I.e 5.62/9.38 × 100%.

That gives 59.9% , which equals 60% when approximated to the nearest percentage.

Final answer:

The nearest percent increase is approximately 59.81%

Explanation:

To calculate the nearest percent increase, we need to find the difference between the selling price and the wholesale cost, and then divide it by the wholesale cost. In this case, the difference is $15 - $9.38 = $5.62. Then, dividing $5.62 by $9.38 gives us approximately 0.5981. Multiplying this by 100 gives us the nearest percent, which is approximately 59.81%.

Answer:

Your correct answer is 48. So, x = 48

Step-by-step explanation:

(x + 34) + (2x + 2) = 180

Therefore, your answer is 48.

Find three consecutive even integers such that the sum of the smallest to the largest 36

Answers


If they were all the same integer, then each one would be
1/3 of 36, and you would have

                                           12  +  12  +  12  =  36 .

But you don't want them to all be the same number.  You
want them to be three consecutive even numbers.

Fine !  Take 2 away from the first 12, and glue it onto the last 12 .
Their sum doesn't change, but now you have

                                             10  +  12  +  14  =  36 .
First, I would set up an equation (assuming 36 is the sum of all 3 numbers). 

x+(x+2)+(x+4)=36
               3x+6=36
                   -6   -6
                   3x=30
                   ---   ---
                   3     3
                   x=10

Now, we just plug in the numbers to find the consecutive integers
10+(10+2)+(10+4)
10+12+14

So your 3 consecutive even integers are 10,12 and 14
