if each dimension of a unit cube is increased by 1. what is the ratio between the surface area of the new cube to that of the original

Answers

Answer:

4:1 or 4/1

Step-by-step explanation:

Original surface area: Each side is 1 * 1 = 1 and there are 6 sides, so 1 * 6 = 6.

New surface area: Each side is 2*2 = 4, and there are 6 sides, so 4 * 6 = 24

The ratio would be 24:6, or 4:1. As a fraction, this would be 4/1

4/1 ^ yea he’s right I remember this

\{15,22,39\}
\{11,21,29\}

Answers

WHAT KIND OF SCHOOL YOU GO TO

{11,21,29} is your answer


Do you need the explanation too? Two sides must add up to be larger than the other side and it must work for every combination, 11+21 is greater then 29 so it works but 5+7 is not greater than 14 so that one doesn’t work.

PLZ DO NOT REPORT

Answers

Answer:

$3.75

Step-by-step explanation:

. Chocolates = $2

. Only has to spend $30

. Milk costs $4

30 divided by 2 = 15

15 divided by 4 = $3.75

To Check: 3.75 x 4 = 15

15 x 2 = $30

Explain: All you have to do is divide 30 by 2 and you will get 15. Then, divide 15 by 4 and you will get $3.75. When you check, you should use the inverse operation which is multiplication, so with that being said, 3.75 x 4 = $15.  15 x 2 = $30.

Your welcome!

Answer:

(30 *insert division symbol* 4) = 26 *insert dividion symbol again* 2 = 13
