Answer:
1.50
Step-by-step explanation:
In the figure,ABC is congruent to ADC . If the square ABCD is dilated by a factor of 2 to form A'B'C'D', the ratio of the area of A'B'C'D' to the area of ABCD is 1/2. Since the dilation is by a factor of 2, so the area of the A'B'C'D' should be smaller than the area of ABCD.

Answer:
or 
Step-by-step explanation:
When we have an exponent that is a negative, it is the same thing as 1 over the positive exponent. So, we move 9^-3 into 1/9^3 and then we evaluate the exponent to get our answer.
Answer:
61.68 mg
Step-by-step explanation:
Given the table :
5:00pm - 400mg
6:00pm - 350mg
7:00pm - 306.25mg
First we obtain the percentage rate at which the drug leaves her system per hour :
Take between 5-6 pm
((400 - 350) / 400) * 100%
(50 / 400) * 100%
0.125 * 100%
= 12.5%
.we can use the exponential function :
A = P(1 - r)^t
r = rate, t = time (hours) ; P= initial amount ; A = final amount
Mg of medicine left when she wakes up at 7:00 am
t = 7:00am - 5:00 pm = 14 hours
P = 400 mg
r = 0.125
A = 400(1 - 0.125)^14
A = 400 * 0.1542100
A = 61.68402913
About 61.68 mg
