Answers

Answer 1
Answer: Start by listing this until you see that X+Y = 50
X can equal: 4,8,12,16,20,24,28,32,36,40,44
Y can equal: 1.5,3,4.5,6,7.5,9
So...
X=11
Y=4
so... 4 sandwiches were bought, and 11 drinks.

Can you express 9 over 9 as a mixed number why or why not

Answers

it is not a mixed number because if you put the same number of the numerator on the denominator it would be a mixed number (1)
you cannot express 9/9 as a mixed number becasue 9 divided by 9 is 1 wth nothing left over, tecnically you can add 0/(any number) and it would remain true becasue 0 OVER anything is 0. (9)/(9) \n 1 (0)/(any_-number) \n 1

A survey of 96 students on campus showed that 29 read the Campus Observer student newspaper that morning, 24 read the news via the Internet that morning, and 20 read the local city paper that morning. Eight read the Campus Observer and the Internet news that morning, while four read the Internet news and the local paper, seven read the Campus Observer and the local city paper, and one person read the Campus Observer, the Internet news, and the local paper. (a) How many read the Internet news or local paper but not both? (b) How many read the Internet news and the local paper but not the Campus Observer? (c) How many read the Internet news or the Campus Observer or both?

Answers

Final answer:

In total, 40 students read either the Internet news or the local paper, but not both; 4 students read both the Internet news and the local paper but not the Campus Observer; and 45 students read either the Internet news, the Campus Observer, or both.

Explanation:

To answer your question, we will use the concept of sets in Mathematics and the principles of the union and intersection of sets. A Venn Diagram can be very helpful in picture this.

(a) How many read the Internet news or local paper but not both?
First, we need to find the total number of students who read either the Internet news or the local paper. This would be the number of students who read the Internet news, plus the number of students who read the local paper, minus the number of students who read both. That would be 24 + 20 - 4 = 40 students.

(b) How many read the Internet news and the local paper but not the Campus Observer?
The answer is given directly in the question. These are the students who read both the Internet news and the local paper, but did not read the Campus Observer, which is 4 students.

(c) How many read the Internet news or the Campus Observer or both?
For this, we add the number of students who read the Internet news to those who read the Campus Observer, and subtract the number of students who read both. This gives us 24 + 29 - 8 = 45 students.

The scale size is 2cm:4m

Answers

I'm not sure which one is the scale size so i'll solve for both...

Ratio is 2cm:4m
0.02m:4m or 2cm:400cm also work as ratios

400cm/2cm=200 (so the scale is 200X smaller than the original)

Option 1::

If the scale of the item is:

l=12cm and w=6cm

then we can solve for the actual size by multiplying the values by 200

l=12cm*200=2400cm or 24m

w=6cm*200=1200cm or 12m

Option 2::

If the original item has a length of 12m and a width of 6m then:

l=12m and w=6m

We can find the scale length by dividing by 200

l=12m/200=.06m or 6cm

w=6m/200=0.03m or 3cm
