Answer:

300ft^2

Step-by-step explanation:

Surface Area = 2bs + b^2 where s = height of each triangular surface and b = base

Surface Area = 2(10)(10) + 10^2
Surface Area = 2(100) + 100
Surface Area = 200 + 100
Surface Area = 300ft^2

The purchase price of a camera is $84. The carrying case is 12% of the purchase price. Tax 6% of the subtotal. What is the total
ICE Princess25 [194]
Hi there! So, we know that the price of the camera is $84, and the carrying case is 12% of that price. Let's find the cost of the case. To find the cost of the carrying case, all you have to do is multiply the price of the camera by the percentage. 84 * 12% (0.12) is 10.08. The price of the carrying case is $10.08. Let's add that price to the price of the camera. 84 + 10.08 is 94.08. $94.08 is the purchase price, but we're not done. We must add the tax in to find the total price. We can add 100% to the tax rate of 6% to get 106% Adding 100% to the amount of tax helps us get straight to the total price. Multiply that by 94.08. 94.08 * 106% (1.06) is 99.7248 or 99.72 when rounded to the nearest hundredth. There. The total price of the purchase is $99.72.

Find CI paid when a sum of RS. 10800 is invested for one year and 3 months at 8% per annum compounded annually. ​
frez [133]

Step-by-step explanation:

Solution :

Here, Principal amount, P=10000 Rs

Rate, r=8.5% per annum

Time, t=1 year and 3 months So, Amount after first year =10000∗(1+8.5100)1

=10000∗108.5100=10850

So, interest after first year =10850−10000=850 Rs

Now, interest for 3 months in 2nd year =10850∗8.5∗3100∗12=230.56 Rs

So, total compound interest 850+230.56=1080.56 Rs
