What is the greatest whole number that is less than 5/2 to the third power divided by 3/4 to the second power?
Free_Kalibri [48]

Answer: 27

<u>Explanation:</u>

  (\frac{5}{2})^{3} ÷ (\frac{3}{4})^{2}

= \frac{125}{8} ÷ \frac{9}{16}

= \frac{125}{8} x \frac{16}{9}

= \frac{125}{1} x \frac{2}{9}

= \frac{250}{9}

= 27\frac{7}{9}

The greatest whole number is: 27

The length of a rectangle is 10 yd less than three times the width, and the area of the rectangle is 77 yd^2. Find the dimension
Vitek1552 [10]

Answer:

W=7 and L=11

Step-by-step explanation:

We have two unknowns so we must create two equations.

First the problem states that  length of a rectangle is 10 yd less than three times the width so: L= 3w-10

Next we are given the area so: L X W = 77

Then solve for the variable algebraically. It is just a system of equations.

3W^2 - 10W - 77 = 0

(3W + 11)(W - 7) = 0

W = -11/3 and/or W=7

Discard the negative solution as the width of the rectangle cannot be less then 0.

So W=7

Plug that into the first equation.

3(7)-10= 11 so L=11

Rearrange the formula to make t the subject:<br> S=d/t
Virty [35]

Answer:

t = d/S

Step-by-step explanation:

S = d/t

Cross multiply

S x t = d

Divide both sides by S

S/S x t = d/S

t = d/S
