Answer:
275 yards of ribbon need to be ordered
Step-by-step explanation:
Figure out how much ribbon, in inches, is needed altogether by multiplying the amounts of ribbon by how many boxes are expected to sell for both box sizes:
Small Boxes:
20 in • 225 boxes = 4500 in of ribbon needed
Large Boxes:
30 in • 180 boxes = 5400 in of ribbon needed
Add it up to see how much you need:
4500 + 5400 = <u>9900 in of ribbon needed in total</u>
<u />
There are 36 inches in 1 yard, so divide 9900 by 36 to see how many yards need to be ordered:
9900 ÷ 3 = 275 yards
(Alternatively, you could divide 9900 by 12 inches in a foot to get 825 feet. Then you would divide 825 by 3 feet in a yard to get 275 yards)
Answer:
Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Step-by-step explanation:
Answer:
we have:
∆BDE is similar to ∆BAC
so their side are proportional :
BD/BD=BE/BC
2/BD=4/(6+4)
BD=2×10/4
BD=5
again
BE/BC=DE/AC
4/10=5/AC
AC=5×10/4
AC=25/2
Now,
<u>AC</u><u>=</u><u>2</u><u>5</u><u>/</u><u>2</u><u> </u><u>or</u><u> </u><u>1</u><u>2</u><u>.</u><u>5</u><u>.</u>
<u>AD</u><u>=</u><u>BA-BD</u><u>=</u><u>5</u><u>-</u><u>2</u><u>=</u><u>3</u><u>.</u>
<u>is</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
