$10- $6.98= $3.02 is your change
Answer:
45.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship ...
Sin = Opposite/Hypotenuse
Filling in the given information, you have ...
sin(V) = 6.6/9.2
V = arcsin(6.6/9.2) ≈ 45.8395°
∠V ≈ 45.8°
_____
It can help to draw a diagram of the triangle, so you can see the letter designations of adjacent and opposite sides and the hypotenuse.
He can arrange the black and white photes in 5 rows because you can make 2 rows of 6 or 6 rows of 2. also you can put 1 rows of 12 or 4 rows of 3 or 3 rows of 4. sam can arrange the color photes in 4 different ways of 18 because he can put 1 row of 18 or 18 rows of 1. Also he can put 2 rows of 9 or 9 rows of 2.
Hope this helps!
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
