Question:

Identify the sets that contain 2 as an element. (Check all that apply.)

A.\ \{2, 3, 4, 5, ...\}

B.\ \{0, 1, 4, 9, ...\}

C.\ \{2, \{2\} \}

D.\ \{\{2\}, \{\{2\}\}\}

E.\ \{\{2\}, \{2, \{2\}\}\}

F.\ \{\{\{2\}\}\}

Answer:

A.\ \{2, 3, 4, 5, ...\}

C.\ \{2, \{2\} \}

Step-by-step explanation:

Required

For which of the options is 2 an element

A.\ \{2, 3, 4, 5, ...\}

The elements of this set starts from 2, then 3 and continues as thus.

Hence: 2 is an element

B.\ \{0, 1, 4, 9, ...\}

From the given elements in the above set, 2 is not listed.

Hence: 2 is not an element of this set

C.\ \{2, \{2\} \}

Here, 2 is listed as an element, 2 is also listed as a subset.

Since 2 is listed as an element, then 2 is an element of the set.

D.\ \{\{2\}, \{\{2\}\}\}

Here, 2 is listed as a subset of {2} and also as a subset of subset of {{2}}.

Since 2 is not listed as an element itself, then 2 is not an element of the set.

E.\ \{\{2\}, \{2, \{2\}\}\}

Here, 2 is listed as a subset of {2} and also as a subset of subset of {2,{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set

F.\ \{\{\{2\}\}\}

Here, 2 is listed as a subset of subset of {{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set

A salesperson is driving from the office to a client, a distance of about 250 kilometers. After 45 minutes, the salesperson pass
ludmilkaskok [199]
<span> <span>Speed is calculated as distance covered, divided by the time taken to cover that distance. In this case, the sales person covered 50KM in 45minutes (which can also be expressed as 3/4 hours). To calculate the speed he used to cover this distance, we divide the distance covered by the time taken. So 50km/3/4hours. This gives us 66.67km/hr. In order to calculate the amount of time the salesperson used to travel from the office to the sales person, we calculate as follows 250km/66.67km/hr. This gives us a total of 3.75 hours or 3 hours 45 minutes.</span></span>

I need help asap.
skad [1K]

Answer:

435=107+82+246

Step-by-step explanation:

I think this is correct. Someone correct me if I am wrong, but I took 435 and subtracted 107, then I took that number and divided it by 4 and took one of those 4 and put it in the equation then multiplied the last three.

The easiest way to solve this is to divide the shape into 2 rectangles.

The first rectangle being the big one on the left with the 12 and 6
and the second one being the little one on the right, next to it with the 5

So 12 x 6 = 72 (dont pay attention to the 7, 5, or 10, because all we need is 1 length and 1 width)

And for the smaller one it is a little bit trickier.

So on the bottom we see that is says 10ft, but we cant use that because what we really need is the measurement between the 5 and 7 on the top of the little rectangle

At the top we see that it says 6ft

We can do 10-6 to find the missing measurement.

Because the length of the whole like is 10, and the length of one of the little lines is 6, so the length of 6 + some number =10

So 10-6 = 4

Which means the number we need is 4

So now we have 5 x 4 = 20

72 + 20 = 92

Answer: 92

I also attatched an image, I hope this helps! Ask me if you have any other questions about this problem!
