<span>It
has no perfect square factors, unless you count 1 = 1^2. That's sort
of a degenerate case we don't usually count, since every integer has
that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!</span>
The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46
so, x =
and y =
Hence, the answer is the first one.
A. If there are only green and yellow M & M’s in the bag, what is the smallest number of
M & M’s possible? 7 M & M’s total
b. If there are 84 M & M’s in the bag all together, how many are green? 24 green ones
c. If red M & M’s were added to the bag in part b to get a total of 100, what is the ratio of green to yellow to red? 6: 15: 4
The formula for the area of a rectangle is:
w = width
l = length
First, we have to convert 2
into an improper fraction, then into a number. The improper fraction would be
. Let's convert that into a decimal.
Let's multiply
The area of the rectangle would be 25 feet!
