Answer:

Step-by-step explanation:

1 surface area of the cube is s*s.

There are 6 faces on such a cube.

Area = 6*s^2                  Divide by 6

Area/6 = 6s^2 / 6           Do the divsion

Area/6 = s^2

s = sqrt(area/6)

Question 2
julia-pushkina [17]

Answer:

A. C = (d-ab)/a

Step-by-step explanation:

a(c + b) = d

a(c + b)/a = d/a

c + b = (d/a)

c = (d/a) - b

a(c + b) = d

ac + ab = d

ac = d - ab

ac/a = d/a - ab/a

c = (d/a) - b

Amelia is getting a new rug put in her room that she picked out at Home Depot. Her room is 8.5 feet wide and 12.3 feet long. If
Kipish [7]

Answer:

$355.47 cents.

Step-by-step explanation

since you want to find the square footage of the entire room, hence Home Depot costs $3.40 per square foot, you would clearly need to find the area.  Basically find what 8.5 * 12.3 is and then multiply that number by 3.40. Once that is done, put a dollar sign on the answer and BOOM, you got it. :)

so $355.47 cents.

Simplify (6⁵/7³) ²<br><br>a 6⁷ / 7¹⁰<br>b 6¹⁰ / 7⁶<br>c 6³ / 7<br>d 12⁵ / 14³​
Tema [17]

Answer:

b. 6¹⁰ / 7⁶

Step-by-step explanation:

(6⁵/7³)²

6 × 6 × 6 × 6 × 6 = 7776

7 × 7 × 7 = 343

(7776/343)²

7776²/343²

7776 × 7776 = <u>60.466.176</u>

343 × 343 = <u>117.649</u>

6¹⁰/7⁶

6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 = 60.466.176

7 × 7 × 7 × 7 × 7 × 7 = 117.649

6¹⁰ = 7776²

7⁶ = 343²

= <u>b</u><u>.</u><u> 6¹⁰ / 7⁶</u>
