AFD = 49
49 + 58 = 108
DAF = 180 - 108 = 72
BFD = 180 - 49 = 131
131 + 20 = 151
BAF = 180 - 151 = 29
DAB = 29 + 72 = 101
DAB = 101
Answer:
3
Step-by-step explanation:
The given statement 5x=4y=12 and x+6y=5 is true.
<u>Step-by-step explanation:</u>
The question comes from linear equations in two variables.
Here, two unknown variables represent a certain situation and their value can be obtained by solving both the given equations.
The cost of cookie is represented by the variable x and cost of doughnuts can be represented by the variable y.
The coefficient of each variable in the equation represent the quantity or the number of units of each baked good.
On comparing the given equations from the data provided in the question, the statement can be stated as true.
Answer: The volume of largest rectangular box is 4.5 units.
Step-by-step explanation:
Since we have given that
Volume = 
with subject to 
So, let 
So, Volume becomes,
Partially derivative wrt x and y we get that
By solving these two equations, we get that
So, 
So, Volume of largest rectangular box would be
Hence, the volume of largest rectangular box is 4.5 units.
Answer:
1 /1 ; 360°
Step-by-step explanation:
Start time = 2:30 pm
Stop time = 3:30 pm
Minute hand makes a complete revolution per hour ;
This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1
The angle turned by the minutes hand :
1 complete revolution = 360°
A circle covers 360°
1 /1 fraction of a circle = 1/1 * 360° = 360°
Hence, angle turned by the minute hand = 360°
