You increase the size of a page by 30%. Then you decrease it by 30%. What is the size of the page now?
Answers
Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).
Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)
Therefore the page had a 9% reduction from its original size or is 91% of its original size.
Answer:
Smaller the size you started with
Step-by-step explanation:
Because for example 100 times .30 is 30 100+30=130 and 130 times .30 is 39 100-39=91. 100 > 91

Answer:Rates. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Flip dat triangle!
Turn in onto its base.
My Geometry teacher used to say, "My students, ahh. Textbooks. They say, 'My pretty little students, here's a formula! I will give you numbers and you plug it in.' Then he would say, 'I don't like textbooks. I'm a rebel! So, I derive the formula.'" He made us derive it. But the formula is this: 1/2 x b x h. Why? The real formula is because two equal triangles are both HALF of a parallelogram, and a parallelogram has formula b x h. So it's 1/2 x b x h.
With that in mind, let's find the height first. Onwards!!
12 mm. What can we do with it? Oh, we know the rectangle has 8 mm!! 12 mm - 8 mm is 4 mm! The height is 4 mm. Onwards to the base!!
Hey, what do we know? The rectangle has length 10 mm. A part of it is 4 mm!! So, what's 10 mm - 4 mm? 6 mm. We got it!!
Plug in the formula!!
1/2 x 4 x 6 is????????
12.
And don't forget the mm!!

What is division?
Division means the separation of something into different parts, sharing of something among different people, places, etc.
A class of 25 students shares a class set of 100 markers. On a day there are 5 students absent. Then we have
The number of the marker for one student will be
Hence, one student has five markers.
More about the division link is given below.
There would be 20 students, and 100 markers. 20/100. You would reduce that fraction to 1/5 So every student would have 5 markers.
