The fraction of the books that are reference books is 5/14 i think. hope that helps !!
Answer:
2
Step-by-step explanation:
A is on the line QA', which is 1.25+1.25 = 2.50 units long*. Thus the scale factor is ...
QA'/QA = 2.50/1.25 = 2
The scale factor is 2.
_____
* There are two points on the line QA that are 1.25 units from A. One of them is point Q. If A' is coincident with Q, then the scale factor is 0, and line segment A'B' is the single point Q. We don't believe that is intended to be the case, so we assume that point A' is farther along AQ, hence 2.5 units from Q.
Answer:
3 + 4p + 8t
Step-by-step explanation:
3 + 2(2p + 4t)
1. Distribute
3 + 4p + 8t
You need to work out the variables of 20 (the last number) first: 1, 2, 4, 5, 10, 20 Lets call these folks "p" At that point you need to work out the components of the main coefficient (the number before the most astounding force of x): 1 Lets call this person "q" At that point you need to make all the conceivable divisions you can with: ±p/q Since q is only 1, we are fortunate, so the conceivable normal roots are: ±1/1,±2/1,±4/1,±5/1.±10/1,±20/1
B = 2h
Area = 121
1/2 × b × h = 121
1/2 × 2h × h = 121
h × h = 121
h^2 = 121
h = square root of 121
h = 11
The height is 11 kilometers
