Answer:
<em>She need </em><em>72 </em><em>index cards.</em>
Step-by-step explanation:
Ms. James has a 6 square foot bulletin board and a 12 square food bulletin board and she wants to cover both boards with index cards without gaps or overlaps.
Each index card has an area of 
square foot.
Dividing the area of each board with the area of the index card will yield the the number of cards she needs to cover up completely.
Let us assume T₁ and T₂ are the number of cards she needs to cover 6 square feet food bulletin board and 12 square feet food bulletin board respectively. So
Therefore, in total she need 24+48=72 index cards.
Answer:
Area = 64 cm²
Step-by-step explanation:
To find the area, we have to follow some steps:
=> <u>Step 1: Make the bases similar:</u>
Since we have 2 bases given 6 and 10 we have to come up with a third base by finding their average:
(6 + 10) / 2
(16) / 2
8
So now that we know our base,
=><u> Our second step is to multiply the base we found by the height of the trapezoid:</u>
Area = common base * height
Area = 8 * 8
Area = 64 cm²
Hope this helps!

Step-by-step explanation:
1 grain = 6×10⁻⁶ g
- 7200 kg =
- 7200000 g =
- 7.2×10⁶ g =
- 7.2×10⁶ ÷ 6×10⁻⁶ =
- (7.2÷6)×10⁶⁻ ⁽⁻⁶⁾ =
- 1.2×10¹² grains
