Answer:
0.5
Step-by-step explanation:
Circumference of a circle = 2πr.
Given, circumference = 3.14 meters.
Therefore,
2πr = Circumference of a circle
or, 2πr = 3.14.
or, 2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14].
or, 6.28r = 3.14.
or, r = 3.14/6.28.
or, r = 0.5.
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²
Answer:
its the top right
Step-by-step explanation:
1/3 times 5/6 = 5/18
We are actually given here a right triangle where EC is
the hypotenuse. The length of one side is AE = 24, and the other side AC is
simply twice BC, so AC = 7:
EC^2 = AE^2 + AC^2
EC^2 = 24^2 + 7^2
EC = 25
Answer:
14. y=2x-5
15. y=-4x+6
16. y=-3/4x-13/2
17. y=2/3x+14/3
18. y=-x+3/2
19. y = 1.5x + 2.25
