1. Formula for volume of a cone is: V = PI * r * h/3

Volume = PI * 1 * 5/3 = 5.24 cubic inches.

2.  Formula for volume of a sphere is: V = 4/3 * PI * r^3

Volume = 4/3 * PI * 1^3 = 4.19 cubic inches.

what is the value of the x variable in the solution to the following system of equations? 2x 2y = 6 x 3y = −1 a. −2 b. 2 c. 5 d.
tatuchka [14]
2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)

(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)

(3) - (4) => 4x = 20
x = 20/4 = 5

1. A chord is 22 cm long. It is 60 cm from the center of the circle.
mezya [45]

Answer:

Radius, r = 61 cm

Step-by-step explanation:

According to the attached figure, we have,

Length of chord, AB = 22 cm

Such that, AP = PB = 11 cm

OP = 60 cm

It is required to find the radius of the circle. We know that radius of a circle is perpendicular to chord. So, APO forms a right angled triangle. Using Pythagoras theorem to find the radius of circle. Let it is r. So,

r^2=60^2+11^2\\\\r=61\ cm

So, the radius of the circle is 61 cm.

A car rental company charges a one-time application fee of 40 dollars, 55 dollars per day, and 13 cents per mile for its cars. A
liberstina [14]

Answer:

A) C(d,m) = 40 + 55d + 0.13m

B) $448

Step-by-step explanation:

Let 'd' be the number of days and 'm' the number of miles driven.

A) The cost function that describes a fixed amount of $40, added to a variable amount of $55 per day (55d) and a variable amount of 13 cents per mile (0.13m) is:

C(d,m) = 40 +55d +0.13m

B) If  d = 5 and m =600, the total cost is:

C(5,600) = 40 +55*6 +0.13*600\\C(5,600)=\$448

The cost is $448.
