Answer:

16.2\ cm

Step-by-step explanation:

we know that

The diagonal of a cube is equal to

D=b\sqrt{3}

where

b is the length of an edge of the cube

we have

D=28\ cm

substitute

28=b\sqrt{3}

b=28/\sqrt{3}=16.2\ cm

Which expression is equivalent to 30 (1/2x - 2) +40 (3/4y-4)? (will add pic)
bixtya [17]

Answer:

C

Step-by-step explanation:

Given

30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4)

Multiply each of the terms in the first parenthesis by 30 and multiply each of the terms in the second parenthesis by 40.

= 15x - 60 + 30y - 160

= 15x + 30y - 220 → C

Is the set of numbers one 1,5,25 and 125 a geometric sequence
Strike441 [17]
Short answer: Yes.
Each member of the sequence is multiplied by 5 to get to the next member of the sequence.

Find the general equation.
tn = a*5^(n - 1)

Example
t4 = 1*5^(4 - 1)
t4 = 1*5^3
t4 = 125 just as the sequence shows.

t5 = 1^5^4
t5 = 625     Any member of the sequence can be found this way.
