40% since the number of books went UP it is a percent increase
Answer:
I. x + y = 9
II. x = 3
III. y/c = 1/4 --> y = 1/4*c
II and III in I
3 + 1/4*c = 9 --> c = 24
(ab)/2 = (3 * 6)/2 = 18/2 = 9
Answer:
26
Step-by-step explanation:
The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.
90+64=154 and 180-154=26.
So 26 is your answer because 90+64+26=180

The x- and y- coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4 is (17, 11)
<h3>Midpoint of coordinate points</h3>
The midpoint of a line is the point that bisects or divides the line into two equal parts
If the line JK is partitioned into the ratio 1:4 with the following coordinates
J(-15, -5) and K(25, 15)
Using the expression below;
M(x, y) =[mx1+nx2/m+n, my1+ny2/m+n]
Substitute the ratio and the coordinates
M(x, y) =[1(-15)+4(25)/4+1, 1(-5)+4(15)/1+4]
M(x, y) = [(85)/5, 55/5]
M(x, y) = (17, 11)
Hence the x- and y- coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4 is ((17, 11)
