To find the length and width of 3 different rectangles that have an area of 48 square inches, you can use the factor pairs that result in 48.
The reason is that to find the area of a rectangle you multiply two dimensions.
2 in x 12 in
3 in x 8 in
4 in x 6 in
On all these either one could be the length and the other the width.
ANSWER:
-14 1/2
STEP-BY-STEP:
-4 1/7 x 3 1/2 = -14.50
-14.50 turned into the simplest fraction it can be, without changing the whole number, is -14 1/2
Rita spent 20$. By multiplying 5 pairs with 4$ we can see that it will equal 20$
for the formula is
Y = starting population x (1-rate of change)^number of years
2010-2001 = 9
Y= 567 x (1-0.015)^9 = 494.89, round up to 495 people
You put the values of x into the equation to work out y, so the y column would be -5, -1, 3, 7 (for question 6)
For question 7, the y column would be 2,2,0,-2
Use these values to draw the graphs :)
