Answer:

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

it takes Joey 1/6 of an hour write one thank you card. how many cards can he write in 3/4 of an hour?
Sauron [17]
1/6 of an hour is equivalent to 10/60 or 10 minutes.
To find out how much 3/4 of an hour is, change the denominator of both fraction so that they match up. We can make this easier by multiplying 4 by 15 to get 60 (hence an hour) and since we multiplied 4 by 15, we also need to multiply 3 by 15 which gets us 45.
We end up with 10/60 and 45/60 or 10 minutes and 45 minutes.
Half of 10 is 5 so we know we'll have a decimal of .5 in our answer.
4 times 10 equals 40 and 40 plus 5 equals 45, so 4.5.

Pls help with this math problem
sukhopar [10]

Answer:

y = 1500 - 63x. See the attached for a graph.

Step-by-step explanation:

Each withdrawal will total $63, which includes $60 cash and a $3 fee. Then x withdrawals will total 63x dollars. This amount is subtracted from the initial account balance of 1500 to give the amount remaining.

If y represents the account balance, the equation can be written as

... y = 1500 -63x

The graph will have a y-intercept of 1500, and a slope of -63.
