Answer:
I believe the second one
Step-by-step explanation:
Because it's angles are all less than 90 degrees so it could be an acute triangle. I am sorry if it is wrong.
Step-by-step explanation:
Substitute the y in the 1st equation with the 2nd equation.
7x + 10(2x + 9) = 36
7x + 20x + 90 = 36
27x + 90 = 36
3x + 10 = 4
3x = -6
x = -2
So now we can find y.
y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.
So x = -2, y = 5.

Answer: 12ft, option D is correct
Step-by-step explanation:
According to the yardstick,
if 3ft height = 6 ft base
Then x height = 24 ft base
We find x height.
To find x height, we cross multiply:
6x = 24 x 3
6x = 72
Divide both sides by 6
x = 72/6
x = 12
Therefore, height is 12ft.

This differs from APY, which takes into account compound interest. The APY for a 1% rate of interest compounded monthly would be 12.68% [(1 + 0.01)^12 – 1= 12.68%] a year. If you only carry a balance on your credit card for one month's period you will be charged the equivalent yearly rate of 12%. However, if you carry that balance for the year, your effective interest rate becomes 12.68% as a result of compounding each month.</span>
