Answer: 12.6 m
Step-by-step explanation:
Use the pythagorean theorem, we get that the height, or x, is
sqrt(22x22-18x18) = sqrt(484-324) = sqrt(160) = 4sqrt(10) = 12.6 m

The amount of cloth needed to make 1 headband is 10 meters.
<h3>Unit value</h3>
- Number of headbands Anne made = 6
- Total clothes used = 3/5 meters
Cloth needed to make 1 headband = Number of headbands Anne made / Total clothes used
= 6 ÷ 3/5
= 6 × 5/3
= (6 × 5) / 3
= 30/3
= 10 meters
Therefore, the amount of cloth needed to make 1 headband is 10 meters.

Answer:
Step-by-step explanation:
So the area of a cube is a²
This means that:
2² = 4cm²
So the area of a triangle is (b*h)/2
This means that:
(3*2)/2 =
6/2 = 3cm²
4cm² + 3cm² = 7cm²
Overall area is 7cm².
Answer:
240
Step-by-step explanation:
If we get 10% off, we still have to pay 100-10 = 90%
Let x be the original price
x *90% = 216
.90x = 216
Divide each side by .90
.90x/.90 = 216/.90
x =240
The original price is 240
