Answer:
The sin A expressed in ratio form is 
Step-by-step explanation:
From the given right angled triangle diagram, sin A is calculated as follows;

Therefore, the sin A expressed in ratio form is 
Answer:
x = 5
Step-by-step explanation:
Since we know that the diagonals bisect each other and divide into equal parts so ➡
x - 2 = 2x -7
2x - x = 7 - 2
x = 5
Answer:
a=2
Step-by-step explanation:
-15a-19-35=-84
-15a-19=-49
-15a=-30
a=2
Unit rate is (cost) per 1 unit
the unit is fluid oz
'per' is fraction
cost/1unit
so we do
2.56/32
divide completely
2.56/32=0.08/1
the unit rate is $0.08 per oz
30/8=3.75
So, you need 4 trays, since you can't have 75% of a tray.
Hope this helps
