Answer:
18.6
Step-by-step explanation:
Adding -20.4 to 39 is the same as subtracting 20.4 from 39. 39 - 20.4 = 18.6.
The answer is 1690. First find
the amount of interest by a single investment by multiplying the investment
amount by the percent interest in decimal form. Then calculate the total by
adding up all the products of investment times interest. Matrices will allow to
multiply two things together and add the products up all at the same time. So
we need to find the investment matrix and interest matrix.
Investment matrix A (transposed) = (a1 a2 a3) = (13,000 12,000 4,000)
Interest Matrix B = (b1
b2 b3) = (0.05 0.06 0.08)
Amount of interest earned = a1b1 + a2b2 + a3b3
Amount of interest earned = (0.05) (13,000) + (0.06)
(12,000) + (0.08)(4,000)
Amount of interest earned = 1690
Answer:

Question:
The circumference of a circle is 16Pi ft. so what is the radius?
Step-by-step explanation:
To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). (The circumference can also be calculated by multiplying 2×radius with pi (π=3.14)).
16 : 2 =<u><em> </em></u><u><em>8</em></u>
