$3.50 + 3·$4.50
Step-by-step explanation:
The total amount of any purchase is computed as the sum of products of quantity and price.
_____
In some instances is is helpful to keep the units (dollars) with the numbers they apply to. Most times, the units will be left off, and you're expected to make sure they work out properly some other way.
total marbles: 2+3+7 = 12
add blue and yellow 2+3=5
7 marbles aren't blue or yellow
probability = 7/12 marble is not one of those
Use the formula:
Radio= r, Height= h
V= 3.14xrx2h
r =25, h=31
V= 3.14 x 25 x 2 (31) =. 4867
V= 4867 cubic inches
Step-by-step explanation:
The area of the triangle is 3 because b•h/2, and the area of the rectangle is 3 because l•w, added together that equals 6, and doubled that equals 12. So I think the answer is C, 12 square feet.
