Nell's mortgage is $50,150 at 10 percent for 30 years.
Rasek [7]

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

<u>EMI on $50150 is</u>

<u>EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32</u>

Therefore the correct option is a.

Hope this help you! ^_^

A scuba diver has a taut rope connecting the dive boat to an anchor on the ocean floor. The rope is 140 feet long and the water
Nostrana [21]
You will need to use the Pythagorean Theorem and plug in the varibles. The rope is the hypotenuse of the right triangle formed, and the 40ft water is the vertical leg, which leaves the ocean floor to be the horizontal leg.[a^{2}+b^{2}=c^{2}\] \[a^{2}+40^{2}=140^{2}\] Then solve for a. \[a^{2}=18000\] \[a=134.164\]
