Answer:
96cm
Step-by-step explanation:
For a triangular prism we find the surface area by doing base times height/ length times width, but since we have a triangle we would have to divide the answer we get by 2. Once we get all the sides we then would have to add them all up.
<h3>front back top </h3>
3X4X1/2 ( HINT: ITS THE SAME AS THE FRONT) 7X5
12X1/2 6= back 35= top
6= front
<h3>Bottom side <u><em>
since we are done finding all</em></u> </h3>
7X4 3X7 <em><u>of the area of the shapes we add </u></em>
28= bottom 21= side <u><em>all of them together.</em></u>
Surface area= 6+6+35+28+21= <u><em>96 cm</em></u>
firstly, I'd like to point out the graph is misleading, if AC is 10 it should be the shorter sides, but it shows as the longer side there.
let's bear in mind that in a rhombus, all sides are equal, even though they may be slanted, the diagonals meet at right-angles always, so the center is simply four 90° angles, and the diagonals bisect each other, namely they cut each other in equal halves.
check the picture below.
The area of the circle would be 16pi
Answer:
Step-by-step explanation:
the simple interest formula= principal* interest rate*time
simple interest : 100000*%2*2 years
simple interest= 4000 dollars
compound quarterly : A=principal(1+r/4)^t
since it is quarterly and have 4 quarters in a year, and 8 in two years.
compound quarterly: 100000(1+0.03/4)^8=106159.88
it is better to invest with compound interest because it add 6159 dollars in two years to the investment of 100000 dollars.
the difference between the interest: 6159.88-4000=2159.88
