Answer:
a) The unit rate of change of d with respect to t is equal to 1.6
b) the graph of the line in the attached figure.
Area = 20 meters square
perimeter = 24 meters
l*w=20
2l+2w=24 divide both sides by 2 and will get
l+w=12 => l = 12-w substitute inside the first equation of area
(12-w)*w = 20
12w -w^2 =20
w^2 -12w +20 = 0
D = 144 -4*20 = 144-80 = 64
w_1,2 = (12 +/- 8)/2 = 20/2 = 10 and 4/2 = 2
l = 12 -w
l_1 = 12 - 10 = 2
l_2 = 12 - 2 = 10
so from these result that the length of the rectangle equal 10 and the width of the rectangle equal 2

Answer:
$94.5
Step-by-step explanation:
The value of the item is $63 and the price of the item selling at 150% of $63.
Now, 150% of $63 will be dollars.
Therefore, there will be profit by selling the item of $63 at the price of 150% of the original i.e. $94.5.
Therefore, the price of an item selling at 150% of its $63 value is $94.5. (Answer)
The nearest whole number would be 13 because it takes more to get to 14 and take less to go to 13 so you answer is 13
7+7=14+10+10=34
So it’s 34 inches.
