13.45 will be the answer

since we are finding the hypotenuse, the formula is a^2 + b^2 = c^2

this will then be 10^2 + 9^2 = c^2

181=c^2

c=13.45 :)

Determine the dimensions of the screen of a 42-inch TV with a 4:3 aspect ratio.
Nitella [24]

For this case, the first thing you should do is know that the measurement of a television is given by the diagonal of the television.

Therefore, to find the value of x, we use the Pythagorean theorem.

We have then:

(3x)^2+(4x)^2=42^2

Rewriting we have:

25x ^ 2 = 1764\\x = \sqrt {\frac {1764} {25}}\\x = \sqrt {70.59}\\x = 8.4

Then the dimensions are given by:

4x = (4 * 8.4) = 33.6\\3x = (3 * 8.4) = 25.2

Answer:

the dimensions of the screen are: 33.6* 25.2

Pedro has a student loan of $62,845. This loan has a simple interest rate of 7% per year. What is the amount of interest that Pe
Nat2105 [25]
I believe it would be $4,399.15 because if you use the formula I=P*R*T
P=62,845
R=0.07 or 7%
T=1 year period
So overall your equation is 62845*0.07*1=$4,399.15
Now at this point the interest is added onto the principal amount to figure out some new amount after one year so:
62845.00+4399.15=$67,244.15
