If there are 10 reams, and each ream is 32 ounces, then there is 320 ounces total im the case! Then, if you know that there are 16 ounces in a pound, then you can do 320/16, and get a total of 20 pounds in the case!
Hope this helped!
Perpendicular means that the slopes are negartive inverses, aka
slope1 times slope2=-1
y=mx+b
slope=m
y=-1/2x-2
slope=-1/2
we need to find negative inverse
-1/2 times what=-1
answer is 2
y=2x+b
input the point (2,-2) to find b
(x,y)
(2,-2)
-2=2(2)+b
-2=4+b
minus 4 from both sides
-6=b
y=2x-6
the equtaion is y=2x-6
B)40 because (4)*50/5 is (4)*10
.3 * 18 = 5.4. 18-5.4 = 12.6$
Or
.7 * 18 = 12.6$
Cos ø = Base/ Hypotenuse
Cos 30 = y/32
Root 3/2 = y/32
y= 16root3
X= 16
