Answer:
Y1 is parallel to Y2 and L1 to L2.
Step-by-step explanation:
A line is 180°. To find the degree the angles I subtracted 117 and 63 by 180 to find thair respective angles. (Also 117+63 equil 180) meaning that the Y's and L's are parallel to each other.
The expression that represents the number of days until only 10% remains is
T((d) 10%) = 100 • (1/2)^3.322
Answer:
(3.8, 6.8)
Step-by-step explanation:
Point B:
Has coordinates (x,y)
AB and BC form a 2:3 ratio.
This means that:


We apply this both for the x-coordinate and for the y-coordinate.
x-coordinate:
x-coordinate of A: 3
x-coordinate of C: 5
x-coordinate of B: x




y-coordinate:
y-coordinate of A: 4
y-coordinate of C: 11
y-coordinate of B: y




Thus the correct answer is:
(3.8, 6.8)
Answer:
The speed of the boat in still water = 8 Km/hr
Step-by-step explanation:
Let the speed of the boat be x
According to question
(x-4)15 = (x+4)5
3x-12 = x+4
⇒x = 8 km/hr
$125.4 is the answer to #1
#2 im not sure how the 10% effects the problem. so i cant help you there
