In 8rows and 3 in each so 8 times 3 is 24
Am thinking you need to dilate the shape by multiplying by 2 and draw your new image!!
Answer:
square root of 25 <square root of 51 <square root of 81
5 <7.14 <9
Given:
Total amount invested = $9,000
interest rates = 4% and 6%
Let x be the part of 9,000.
Note that annual return on each investment is the same.
0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540
x = 540/0.10
x = 5,400
0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216
total interest for the year : 216 + 216 = 432
Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate
Interest rate would be 4.8% to get the same interest from the whole 9,000.
Slope is the change in Y over the change in x:
Slope = (42 - 18) / (8-2)
Slope = 24/6
Slope = 4
