Answer:
The ordered pair is not a solution as both sides of the equation do not equal each other.
Step-by-step explanation:
(3,2); x + 6y = 13
(3) + 6(2) = 13
3 + 12 = 13
15 = 13
Answer:
9,424.8 cm^3
Step-by-step explanation:
V = A of circle x h
= πr^2 x h
=(3.1416)(10)^2 x 30
=(3.1416)(100) x 30
=314.16 x 30
=9429.8
Multiply by the reciprocal, 4/3
Answer:
The length around the figure in terms of r is 2r (
+ 4).
Step-by-step explanation:
The perimeter of an object is the total length of the boundary of the object.
The figure consists two similar semicircle and a rectangle.
Adding the two semicircles, a complete circle is formed. The circumference of a circle = 2
r.
The rectangle has a length which is twice its height.
i.e l = 2h
But,
r =
(the diameters of the semicircles equal the height of the rectangle)
⇒ h = 2r
Thus, one side length of rectangle = 2 × 2r (l = 2 × h)
= 4r
The length around the figure in terms of r is:
= 2
r + 4r + 4r
= 2
r + 8r
= 2r (
+ 4)
The length around the figure in terms of r is 2r (
+ 4).
Divide 7 by 20 to get the decimal form of 7/20 and then see which one of the statistics match it should be the on base statistic
