Mathematics

Effectus [21]3 years ago
8 0

Step-by-step explanation:

Let edge length of cube be x units.

volume \: of \: cube =  \frac{27}{64}  \\  \\  \therefore \:  {x}^{3}  = \frac{27}{64}  \\  \\ \therefore \:  {x}^{3}  = \frac{ {3}^{3} }{ {4}^{3} }  \\  \\ \therefore \:  {x}^{3}  = (\frac{ {3}}{ {4} } )^{3} \\  \\  \therefore \:  {x} = \frac{ {3}}{ {4} }  \\  \\ \therefore \:  {x} =0.75 \:  {unit}

Hence, length of edge of cube = 0.75 units

i need help with a math problem right now it says A car rental agency advertised renting a car for $24.95 per day and $0.26 per
Dominik [7]

Answer:

He can drive 481 miles if David rents his car for three days

Step-by-step explanation:

This is true because if you take the 24.95 and multiply it by 3, because he rented it for three days, you'll get 74.85. Then you'll subtract 200 (the total money that can be spent) by 74.85 you'll get 125.15. Divide the remaining number, 125.15 by 0.26 to get 481.34. Take the decimals away because you don't need it, if you want to be sure it's correct you can multiply 481 by 0.26 to get 125.05 which is lower than 125.15 so it good because if you use 482 besides 481 it will be higher than the amount of money David can spend, that's why 481 is the right answer.

BaLLatris [955]

Answer:

If he eats more then 12 lunches in a month he should take Plan B, if he eats less then 12 lunches a month he should take Plan A.

Bring the fraction: b/7a^2c to a denominator of 35a^3c^3
Rina8888 [55]

Answer:

5abc^2/35a^3c^3

Step-by-step explanation:

To bring the fraction: b/7a^2c to a denominator of 35a^3c^3, find the dividend when the 35a^3c^3 is divided by 7a^2c

=35a^3c^3/ 7a^2c

Recall that

a^x/a^y = a^x-y

Hence

35a^3c^3/ 7a^2c = 5a^3-2c^3-1

= 5ac^2

Now multiply the numerator and denominator by the result

b/7a^2c = (b * 5ac^2)/(7a^2c * 5ac^2)

Recall that

a^x * a^y = a^x+y

Hence

b/7a^2c = (b * 5ac^2)/(7a^2c * 5ac^2) = 5abc^2/35a^3c^3
