svet-max [94.6K]

complete question:

A mini game cube is covered in different  colors and has a side length of 1.8 inches.  Which of the following would represent the  amount of space covered in various colors?

A. 116.64 in2

B. 3.24 in2

C. 19.44 in2

D. 10.8 in2

Answer:

C. 19.44 in2

Step-by-step explanation:

A cube is a 3 dimensional figure bounded by 6 square faces. All the sides of a cube are equal in length. The picture below is a cube. The amount of space covered in different colors will be the surface area of the cube.

surface area = 6L²

where

L = length

L = 1.8 inches

surface area =  6 × 1.8²

surface area  = 6 × 3.24

surface area = 19.44 inches²

The coordinates of the endpoints of the diameter of a circle are (-1,5) and (3, -1). The center of the circle has coordinates
Setler79 [48]

Answer:

ans=(-2,2)

Step-by-step explanation:

let the end point of circle diameter (-1,5) and (3,-1) be (x1,y1) and (x2,y2) respectively

using mid point formula

(x,y)=(-1,5)/2+(-3,-1)/2  [center point is equal to mid point of  diameter)

       =  (-1+(-3))/2+(5-1)/2

       =(-2,2)

center coordinate of circle=(-2,2)

exis [7]

Answer:

24

Step-by-step explanation:

Let Noah = x.  I will write the equation in order of appearance with Noah first.

x + 3x + (3x + 5) + (3x + 12) + (x - 4) + 2(x-4) = 317

Distribute where needed and remove parentheses

x + 3x + 3x + 5 + 3x + 12 + x - 4 + 2x - 8 = 317

Collect like terms

13x + 5 = 317

Move the constant to the right of the equal sign and do the math

13x = 312

Divide both sides by 13
