27. The interest rate that doubles a sum in 10 years is<br>a) 12%<br>b) 11%<br>c) 10%<br>d) 9%​
avanturin [10]

Answer:

Interest rate of 7%.

Step-by-step explanation:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

We want to find t for which A(t) = 2P when n = 1, t = 10. So

A(t) = P(1 + \frac{r}{n})^{nt}

2P = P(1 + r)^{10}

(1 + r)^10 = 2

\sqrt[10]{(1 + r)^10} = \sqrt[10]{2}

1 + r = 1.07

r = 0.07

So a interest rate of 7%.

What is the surface area for the figure in the image above one ☝️ #6 pls
klemol [59]

Answer:

answer: 148

Step-by-step explanation:

To find surface area you have to do all sides and multiply base x height so The top and bottom would be 11 x 2 = 22 the sides would be 4 x 2 = 8 the front and back would be 11 × 4 = 44 sense each face has a matching one each of these will be added twice so 22 + 22 + 8 + 8 + 44 + 44 = 148 So 148 is our surface area Hope this explains well!
