N = number of compounding periods
Years = log (total / principal) / n * log (1 + rate / n)
Years = log (750 / 500) / 4 * log (1 + .025/n)
Years = log (1.5) / 4 * log (1<span><span>.00625) </span>
</span> <span>Years = 0.17609125906 / 4 * 0.0027058933759

Please help! This is 6th grade math on surface area.
KatRina [158]

Answer:

<u>144</u>

Step-by-step explanation:

Ok. I love problems like this.

You just have to find the surface are of each part and add it up!

To find the surface area of a rectangle, you multiple the base and the height. To find the surface area of a triangle, you multiple the base and height, and divide by 2 (because its half of a rectangle).

<u>Left rectangle:</u> 3*ll=33

<u>Middle rectangle:</u> 4*ll=44

<u>Right rectangle:</u> 5*ll=55

<u>Top triangle:</u> 3*4=12

                      12/2=6

<u>Bottom triangle:</u> 3*4=12

                           12/2=6

<u>ADD THEM ALL!!!</u> 33+44+55+6+6=<u>144</u>

<u></u>

<u></u>

(Also can I please please please have brainliest? I need it to level up!)
