Two 2 1/2 inch plastic strips and two 5 1/3 inch plastic strips are used to form a rectangle. What is the perimeter of the recta

svp [43]

In this question the given information's should be closely noted. The length and width of the perimeter are already given. Based on those information's the answer to the question can be easily deduced.
Length of the rectangle = 2 1/2 inch
   = 5/2 inch
Width of the rectangle = 5 1/3 inch
   = 16/3 inch
Then
Perimeter of a rectangle = 2 ( Length + Width)
      = 2 [(5/2) + (16/3)]
   = 2 [ (45 + 32)/6]
   = 2 * (77/6)
   = 77/3 inch
   = 25 2/3 inch
So the perimeter of the rectangle in question is 25 2/3 inch. I hope the procedure is clear to you.

A lawyer charges a $75 consultation fee and then $120 per hour thereafter.

Ainat [17]

Answer:

(a) The dependant veriable is the $120 per hour and the independant veriable is the $75 consultaion fee.
(b) The table of vaules for this would look like this, $\frac{C}{T} \frac{75}{0} \frac{195}{1} \frac{315}{2} \frac{435}{3} \frac{555}{4}$ , where C = cost and T = time.
(c) The relationship between C and T is linear, beacause with the more hours you take the cost increases.
(d) Yes, it is sensible because the points would be in line due to the steady increase of the hourly rate.

(e) For every hour spent the cost increases 120 dollars.
(f) The fixed cost is 75 dollars for consultation and the veriable cost is 120 per hour.

Answer:

$V=90$

Step-by-step explanation:

<u>Step 1: Find the volume of the cone</u>

<u /> $V = \frac{\pi *r^{2}*h}{3}$

<u>Plug in the values</u>

<u /> $V = \frac{\pi *3^{2}*10}{3}$

<u>Simplify and Solve</u>

<u /> $V = \frac{\pi *9*10}{3}$

$V = \frac{90\pi }{3}$

$V = \frac{90*3 }{3}$

$V=90$

Answer: $V=90$
