Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
1) Value of
since sin45° = 1/√2
Therefore 
2).Value of 
Since cos 30° = √3/2
Therefore 
3). Value of 
since tan 60° = √3
therefore 
4). Value of 
Since sin90°=1
Therefore 
Answer:
Volume of a cuboid = 42 cm³
Step-by-step explanation:
Volume of a cuboid = side A × side B × side C
Side A = 2 cm
Side B = 3 cm
Side C = 7 cm
Volume of a cuboid = side A × side B × side C
= 2 cm × 3 cm × 7 cm
= 42 cm³
Volume of a cuboid = 42 cm³
Answer:24.2 m
Step-by-step explanation: yea u gotta use the metric system
You are looking for how many miles the car went in 1 hour. You know it went 500 miles in 6.7 hours. To find how many it went in 1 hour simply Divide 500 miles by 6.7 hours.
500 miles/6.7 hours = ____ miles in 1 hour
Answer:
x = 3 && y = - 1
Step-by-step explanation:
Just solving the two equations
the first equation
y = 4/3 x +3
y - 4/3 x = 3 ..............................................(1)
the second equation
y = -2/3x -3
y + 2/3 x = -3 ..............................................(2)
by substracting 2 from 1
-4/3x - 2/3x = -6
divide by -1
4/3x +2/3x = 6
6/3x = 6
2x = 6
x= 3
then subsititute by value x in any of given eqautions
