A cube has a edge of 8 cm it is cur into two equal parts calculate the ratio of total surface area

chubhunter [2.5K]

Answer:

$Ratio = 3: 2$

Step-by-step explanation:

Given

Shape: Cube

$L = 8cm$

The surface area is calculated as:

$Area = 6*L^2$

$A_1 = 6*8^2$

$A_1 = 384$

When it is cut by half; the length is affected; so, it forms a cuboid of the following dimension:

$L = \frac{8}{2} = 4$ --- Length

$W = 8cm$ --- Width

$H = 8cm$ --- Height

The surface area is:

$Area = 2 *(L*W + H * L + W * H)$

$A_2 = 2 *(4*8 + 8 *4 + 8 * 8)$

$A_2 = 2 *128$

$A_2 = 256$

So, the ratio of surface area is:

$Ratio = A_1 : A_2$

$Ratio = 384 : 256$

Divide by 128

$Ratio = 384/128 : 256/128$

$Ratio = 3: 2$

Put this into slope form x/2 + 2y= 6

Inga [223]

Answer:

y=-1/4x +3

Step-by-step explanation:

x/2 + 2y = 6

Subtract x/2 from both sides

2y=-x/2 +6

Simplify by dividing by 2

y=-1/4x +3

A gym offers three levels of membership based on the number of visits per month, as represented by the table. Kaleigh wants to k

Otrada [13]

Answer:

graph one

Step-by-step explanation:

Let

x ----> the number of visit per month

y ----> the total cost

we know that

Observing the table

1) For the interval of x equal to ----> [0,12] (close circle both points)

The domain is all whole numbers greater than or equal to 0 visits and less than or equal to 12 visits

The value of y is

y=5x+15

For x=0 ----> y=$15

For x=12 ----> y=5(12)+15=$75

The range is the interval ----> [15,75] (close circle both points)

All real numbers greater than or equal to $15 and less than or equal to $75

2) For the interval of x equal to ---->(12,16] (open circle at left and close circle at right)

The domain is all whole numbers greater than 12 visits and less than or equal to 16 visits

The value of y is

y=4x+32

For x=12 ----> y=4(12)+32=$80

For x=16 ----> y=4(16)+32=$96

The range is the interval ----> (80,96] (open circle at left and close circle at right)

All real numbers greater than $80 and less than or equal to $96

3) For the interval of x equal to ---->(16,24] (open circle at left and close circle at right)

The domain is all whole numbers greater than 16 visits and less than or equal to 24 visits

The value of y is

y=3x+42

For x=16 ----> y=3(16)+42=$90

For x=24 ----> y=3(24)+42=$114

The range is the interval ----> (90,114] (open circle at left and close circle at right)

All real numbers greater than $90 and less than or equal to $114
