Did you ever get the answer?
You subtract 3 miles from the 5.5 miles which gives you 2.5
<u><em>Answers:</em></u>
AD = 10 units
BD = 12 units
<u><em>Explanation:</em></u>
<u>1- getting AD:</u>
In an isosceles triangle, the two non-parallel sides are equal.
It is given that trapezium ABCD is isosceles which means that AD = BC
<u>We are given that:</u>
BC = 10 units
<u>Therefore:</u>
AD = BC = 10 units
<u>2- getting DB:</u>
In an isosceles trapezium, the diagonals are congruent
Since the given trapezium is isosceles and AC and BD are its diagonals, therefore:
AC = BD
<u>We are given that:</u>
AC = 12 units
<u>Therefore:</u>
BD = AC = 12 units
Hope this helps :)
The diagram shows that angle AQB = angle BQC
So 5x= 8x-24
3x= 24
x=8 (first answer)
AQB= 5(8) = 40 (second answer)
BQC= 8(8)-24 = 64-24 = 40 ( third answer)
AQC = AQB+ BQC
AQC= 40+40 = 80 (Fourth answer)

4 grams sample will be left after 1 year
Step-by-step explanation:
The decay function for percentage decay is given by:
Here,
a is the initial value
r is the rate
x is the number of time periods
Given
Initial value = 100 grams
Rate = 6% = 0.06
Time = 1 year = 52 weeks
Putting the values in the formula
Hence,
4 grams sample will be left after 1 year
