Answer: arcsec
Step-by-step explanation:
Answer:
0.8 or 8/10
Step-by-step explanation:
The original length of AB is 7.62. If we dilate it with the scale factor 2, the length will be 15.23.
The slope of the line remains the same even if we dilate it, so it will remain 0.43.
(y2-y1/x2-x1)
Explanation: The answers are taken from by solving on the graph
Answer:
Salma, joe, and alan sent 14, 69, and 23 text messages respectively
Step-by-step explanation:
Given that Salma, joe, and alan sent a total of 106 text messages during the weekend, it means that
s + j + a = 106 where s, j, and a are the number of messages sent by Salma, joe, and alan respectively
Given salma sent 9 fewer messages than alan
s = a - 9
Joe sent 3 times as many messages as alan
j = 3a
hence
a - 9 + 3a + a = 106
5a - 9 = 106
5a = 106 + 9
5a = 115
Divide both sides by 5
a = 115/5
= 23
s = 23 - 9
= 14
j = 3* 23
= 69
