The number of bricks= Total height of stack/ height of a single brick.
No. of bricks=3 1/2 ÷ 1 3/4
Convert the fractions into improper fractions;
No. of bricks= 7/2÷7/4
No. of bricks=
No. of bricks= 2
Step-by-step explanation:
the midpoint between 2 points (x1, y1) and (x2, y2) is simply ((x1+x2)/2, (y1+y2)/2).
so,
1.
(9, 7) to (4, -3)
midpoint is ((9+4)/2, (7+ -3)/2) = (13/2, 4/2) = (6.5, 2)
2.
(-7, -5) to (2, 1)
midpoint is ((-7+2)/2, (-5+1)/2) = (-5/2, -4/2) = (-2.5, -2)
3.
now we have the midpoint and need the second point.
(4, 2) over (3, 4) to (x, y)
3 = (4 + x)/2
6 = 4 + x
x = 2
4 = (2 + y)/2
8 = 2 + y
y = 6
4.
(-2, 1) over (-3, 2) to (x, y)
-3 = (-2 + x)/2
-6 = -2 + x
x = -4
2 = (1 + y)/2
4 = 1 + y
y = 3
Answer:
.4 yards of fabric were used for each pillow.
Steps:
2/5=0.4 (or 
)
5: 90 can also be written as a fraction 5/90 then reduce the fraction
5/90 (5*1=5/5*18=90) so it reduces to 1/18
the ratio simplified is 1:18
