Answer:
126
Step-by-step explanation:
21 + 4 = 25 (blue plus white marbles)
150/25 = 6 (all the marbles divided by how many we know are white and blue)
21 x 6 = 126
Answer:
0.75 could be a 25% discount. 1.06 could be a sales tax.
Step-by-step explanation:
If p is the original price, then 1.06p could be the amount after a 6% tax is include. Then multiplying by 0.75 could indicate a 25% discount (if you <u>don't</u> pay 25% = 0.25, then you <u>do</u> pay 75% = 0.75).
In case you're wondering about discounting <u>first</u> then charging tax, the result is the same because the multiplication can be done in either order.
0.75(1.06p) = 1.06(0.75p)
Answer:
You can hold 188.19 or a rounded 188 pounds per cubic feet
Step-by-step explanation:
First we need to find the area which is 271
I found this using the formula 2(WL+HL+HW)
If you can fit 271 square feet then you need to divide that by 4 to find cubic feet.
if you do this you get 67.75 cubic feet
next divide 67.75 by 0.36
you get 188.19
F= hypotenuse
E= opposite
G= adjacent
This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3
