Yes, you are correct. Key word is circular, so we are talking about a circle. pi = circumference of a circle / diameter --> pi = C / d Solve for C C = pi*d = (3.14) *(10 ft) = 31.4 ft, assuming the approximation of 3.14 for pi.
Think of a right triangle. The airport is the vertex of the right angle. Plane A is 70 miles north (Straight up). Plane B is 168 miles East (Straight right). From plane A to B would be side C of the right triange. C^2 = A^2 + B^2 C = sqrt (A^2 + B^2) C = sqrt (70^2 + 168^2) C ...
No, look at your answer... Your length is 4 times as long as your width... How did you come up with your answer?
If X^2-5 is the denom, then the domain would be all X such that the denom does not equal 0. So find when x^2-5=0 x=sqrt(5) (Both positive and negative) So the domain is all real numbers, such that X does not equal +- sqrt (5)
Just wanted to say thanx for the help Bob
Greg reacts 5.0 moles of hydrochloric acid(HCL)with 1.5 moles of barium hydroxide(Ba(OH)2).Which reagent is the limiting reagent, and which is in excess?If the reagent runs to completion,how many moles of barium chloride(BaCl2)will be produced? CAN SOMEONE PLEASE HELP ME.CHEMI...
Robby if you need more help,type ur question ino the search bar on your computor and a site titled chap15 fd.valenciacollege.edu will come up and it will break down complete indtructions on how to go about figuring out this question.I hope this helps.
Convert the 9m of cloth to cm = 900 cm to start with. She has 90 cm of cloth left so she used 900 cm - 90 cm = 810 cm of cloth Let X = cloth for tablecloth Let 2X = cloth for each cushion cover. The equation would be: 810 = X + 4 * 2x 810 = X + 8X 810 = 9X X=90cm 2X=2(90cm) = ...
$38.40 = (1-0.40)* Price Price = $38.40 = $64.00 ------- 0.6
BAD is correct. It is 84. If you would like to use algebra, do the following: x:= Unit Digit Number y:= Tens Digit Number The units digit is 4 less than the tens digit number so We know that x=y-4 The tens digit is twice the units digit so we know that y=2x Now we can take the...
