This is asking what is z and y, so you must know that a triangle is 180 degrees, so if it is 180 degrees, than all three angles that the triangle has must add up to 180 for every single triangle for it to be a triangle. So you have 45 degrees and 47 degrees, which adds up to 92 degrees, so in order to find y you need to subtract 92 from 180, which is 88. 88 is the missing number, and the missing number in this triangle is y, so y= 88 degrees. This can fool you because it looks like 90 degrees, but it is actually 88. Z is a little trickier, because y isn't 90 degrees, if it was than z would be a direct reflection of y, but it isn't, so we must find the exact angle for this variable. I see it like this, if y is 88, than it is smaller than 90 obviously, so it is acute. If that line keeps going down, than really z would be bigger than y, because that line is going down but it is so hard to tell. So if y is smaller by 2 degrees, than z would be bigger by 2 degrees, meaning that z is 92 degrees, since it is slowly decreasing. Hope this helps
1.)
Old Number:35
New Number:45
Now, subract the new number(45) from the old number. (35)
45-35 is 10. Now divide the old number (35) by 10.
You'll get 3.5. 3.5%, increase is the answer for #1.
2.) Old: s (students)
New: 36,750
Do 100+5 (Addition because we do not know what the old number is.) 100+5 is 105. Move decimal over twice and you get 1.05. Multiply 36,750 by 1.05.
There were 38,587.5 kids last year.
3.)Since the discount is 15% off, do 100-15=85. Now, move the decimal over from the percent, and that makes that .85. Now multiply 50x.85. You get 42.5, or $42.50. Now the coupon is 10%, So subtract 100-10, giving you 90. Now move the decimal over. .90. Multiply 42.5 (or 42.50) by .90. You get 38.25. You do have enough money.
4.) Subtract 100-15, giving you 85. Move decimal over from percent. .85.
Now you would multiply .85 times k. B should be the answer.

Step-by-step explanation:
Answer:
2,3
Step-by-step explanation:
Let the first number be x
Hence, its next consecutive integer = x+1
By Factorizing the expression on the LHS. we get it equal to :-
Hence, we get two solutions for x, x=2, x= -3/5
As x is an integer, x=2 is the most suitable solution in this case.
Hence,
The numbers are 2,3
The first thing you have to do is order them least to greatest. Once that is done you need to find your first, second and third quartile. to find them is simple. You have to find the median of the data set. Then from the number on either side of the median you have to find the median of this data sets. The median of the entire set is your second quartile then the medium to the left is your first and the median to your right is the third quartile. For the number line you need to make numbers that are appropriate for the number range. Then place your least number, the first, second, and third quartile, then place your greatest number. then draw a line up from the median and the first and third quartile and create a box.
