9 5/6 - 2 1/3
9 5/6 - 2 2/6
9 - 2 = 7
5/6 - 2/6 = 3/6
7 3/6
3/6 = 1/2
7 1/2
There would be 81 in grade 5
and 68 in grade 6
because 10% of 90 is 9 so 90 - 9 =81
and 15% of 80 is 12 so 80 - 12 = 68
Answer: 7 3/10
seven as a whole number, and .3 equals to 3/10 when converted
A = deposit at US bank
b = deposit at 7/4 bank
c = deposit at Catch bank.
we know her total is 3886, thus a + b + c = 3886.
now, we know whatever "b" is, the amount at US bank, "a", is 3 times that much, thus a = 3b.
(3b) + b + c = 3886.
whatever% of anything, is just (whatever/100) * anything.
we know Catch bank gets 45% of whatever the sum of the other two is, well, US bank gets "3b", 7/4 bank gets "b", their total is 3b + b = 4b, and Catch bank gets 45% of that, (45/100) * 4b

how much is it for the Catch bank? well, (45/100) * 4(670).
A right triangle does have perpendicular line because they can cross if the lines go on forever
A quadilateral is a 4 sided shape so if you talking about the square or a rectangle or a parralelogram no it does not have perpendicular sides BUT if you are talking about a trapezoid it does have pependicular side
HOPE THIS HELPS!!!!!!! ;-)
