Answer:
368 cm²
Step-by-step explanation:
Bottom: 12 * 10 = 120 cm²
Front and back (square): 2 * (10 * 10) = 200 cm²
Front and back (triangle): 12*8/2 = 48 cm²
Total = 120 + 200 + 48 = 368 cm²
Answer: 80%. Hope this helps, please consider making me Brainliest.
Step-by-step explanation:
To find the percentage, divide the sale cost by the original cost:
27.60/34.50
Let's multiply both sides by 10 to make the operation easier:
27.6/34.5 ( I eliminated the zero's because they kind of have no use) -->
276/345, now solve:
276/345 = 0.8
0.8 = 80%
The percentage is 80%.

Answer: Charlotte's speed in meter/second is 2.5m/s.</h3>
Step-by-step explanation:
Given speed of Charlotte in kilometer per hour = 9 km/h
We need to find the Charlotte's speed in meter per second.
We know 1 kilometer = 1000 meter
And 1 hour = 3600 seconds.
Plugging those values of km and hour in given speed in km/h, we get
![9\ \frac{km}{h} = 9\times \ \frac{1000m}{3600 seconds}](https://tex.z-dn.net/?f=9%5C%20%5Cfrac%7Bkm%7D%7Bh%7D%20%3D%209%5Ctimes%20%5C%20%5Cfrac%7B1000m%7D%7B3600%20seconds%7D)
.
Therefore,
<h3>Charlotte's speed in meter/second is 2.5m/s.</h3>
