Answer:
<em>Maya needs 33 bags</em>
Step-by-step explanation:
Let's call x the number of bags of soil. If each bag contains 1.5 cubic feet, then "x" bags do not contain a volume of:
1.5x.
As a volume of 4.5 cubic feet has been published.
We need 54 cubic feet.
Then
Now we must solve the equation for x.
So you'll want to get your mixed number(1 4/7) and convert it into an improper fraction (11/7) this can be achieved by adding the numerator by the whole number than multiplying the sum of that by the denominator and getting 11/7. After that you multiple them, 11 x 2 and 7 x 5 so the answer will be..
22/35
First you must divide 22.5 by 100.
22.5 / 100 = .225
Then add 1.
.225 + 1 = 1.225
Finally times 7800 with 1.225
7800(1.225) = <span>9555
$9555 is the answer.</span>
Which quadrilaterals always have four right angles?
The answer to this is, a square and a rectangle. Squares and rectangles always have 90° angles, for each angle and their interior angles add up to 360°
Answer:
2x -7
2x 4x² -14x
-1 -2x +7
Step-by-step explanation:
4x²-16x+7 factors as
(2x-7)(2x-1)
So the grid would be:
2x -7
2x 4x² -14x
-1 -2x +7
