A cuboid has a square base.
padilas [110]

The length of one side of the square base is 8.5 centimeters.

<u>Given the following data:</u>

  • Volume of cuboid = 867 cm
  • Height = 12 cm

To find the length of one side of the square base:

Mathematically, the volume of a cuboid is given by the formula:

Volume = Base \; area × Height

Substituting the given values, we have:

867 = Base \; area × 12

Base\;area = \frac{867}{12}

Base area = 72.225 cm^2

Now, we can find the length by using the formula:

Area \;of\;a \;square = length^2

72.25 = length^2

Length = \sqrt{72.25}

<em>Length</em><em> = </em><em>8.5 centimeters</em>.

Therefore, the length of one side of the square base is 8.5 centimeters.

Can someone help me with question 5? I don't know what to do!!!
cupoosta [38]
To find the rate, first you divide 180mi/3hr to get 60mph. On the first day they were traveling at a rate of 60mph. It says that on the second day, they drove at the same rate and drove 300 miles. This means you divide 300mi/60mph to get 5hr. They drove 5hr on the second day. And finally, the question asks how long they drove total, so you add 3hr+5hr to get 8hr total.
Answer is 8hr.

Find the value of the expression 0.5^10/0.5^7
SIZIF [17.4K]

Answer:

The solution is:

  • \frac{0.5^{10}}{0.5^7}=0.125

Step-by-step explanation:

Given the expression

0.5^{10}\div 0.5^7

Solving

\frac{0.5^{10}}{0.5^7}

\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

so

\frac{0.5^{10}}{0.5^7}=0.5^{10-7}

\mathrm{Subtract\:the\:numbers:}\:10-7=3

=0.5^3

=0.125        ∵ 0.5^3=0.125

Therefore, the solution is:

\frac{0.5^{10}}{0.5^7}=0.125
