Answer:
Step 2 shows Emily's first mistake.
Step-by-step explanation:
3(2) = 6
But instead of this Emily wrote 3(2) = 9.
Answer:
16 years
Step-by-step explanation:
Given data
Principal= $8500
Rate= 4.5%
Final amount= $17,323
The expression to find time in compound interest is given as
t= ln(A/P)/r
substitute
t= ln(17323/8500)/0.045
t= ln(2.038)/0.045
t=0.711/0.045
t= 15.8 years
Hence the total time is about 16 years
To find surface area, you can find the area od all sides and add them together
First, area of an triangle is 1/2 length times width
So you do 1/2 6*9= 1/2 54= 27 The area of the three triangles are 27
27 times 3 is 81
81 plus the base of 15.6 is 96.6
The surface area is 96.6 meters squared
The answer is 106 degrees. This is because 22 degrees + 52 degrees + 106 degrees = 180 degrees, completing the angles.
Hope this helps!
