30divided by 20 is 1.5 minutes / 1 minute 30 second
Can be worked out but 30 divided by 10 is 3 divided by 2 is 1.5
Answer:
r = 5.696 and θ = 157.17°.
Step-by-step explanation:
the point is (-5.25,-2.21). The distance from the point to the origin is calculated with the formula
r = 5.696 m.
I drew the point and the distances in the plane. to find te angle we can use the sin formula:
sin(θ) =
θ = .
within the range of -180° and 180° the angle will be θ = 180-22.83 = -157.17°
Answer:
Width = 12 feet
Step-by-step explanation:
Given that,
Area of a rectangle is 168 square feet.
The ratio of the width to the length is 6:7.
Let the length is 7x and width is 6x.
According to question,
Area = 168 sq feet
l×b=168 sq feet
7x × 6x = 168
42x² = 168
x² = 4
x = 2
Length = 7x = 7(2) = 14 feet
Breadth = 6x = 6(2) = 12 feet
So, the width of the rectangle us 12 feet.
I know a=pi*r^2 anyways, the triangle is:4*8/2=16 The semicircle is: 4pi because 4 is diameter, /2 then square u still get 4. 4*3.14 = 12.56 12.56 + 16 = 28.56.
