Answer:
Step-by-step explanation:
Given that:
Length (l) = 13 cm
Width (w) = 8 cm
Perimeter of the rectangle = 2(l + w) units
P = 2(13 + 8)
P = 2 (21)
P = 42
Well 100 ÷ 4 = 24 so 3/4 =75/100 and three hours before ten would be 7:00 then you take fourth minutes from the remainder ( 30 mins) and it had to go back an hour because you can't do 30-40 (don't stubtract in time but for this you can you just have to know that 60 mins= 1hr and don't EVER do this: 5:75 <- this is incorrect time.)
umm... 6:50?
We are given all three angles here:
Angle A =68 degrees
Angle B =90 degrees
Angle C =22 degrees.
Now let us calculate :
sin (A) = sin (68) = 0.927
cos (B) = cos (90) = 0
sin (B) = sin (90) =1
cos (C) = cos (22) = 0.927
tan (C) = tan(22) =0.4040
So we can see that sin (A) and cos (C) are both equal to 0.927.
So cos (C) is the correct option.
Answer:
3770 mm.
Step-by-step explanation:
The diameter of of the wheels is 60mm, that means the radius is 30mm.
Now for one revolution of the wheels, they cover the distance of 
on the ground.
For 20 revolutions, the distance covered will be 20 times this.
Thus
Which is our answer.
The axis of symmetry would be x=4.
