8 0

The solution for the problem is:
I will first get the first five terms so that I could easily locate the third term of this problem:So, substituting the values:
T(1) = 1^2 = 1T(2) = 2^2 = 4T(3) = 3^2 = 9T(4) = 4^2 = 16T(5) = 5^2 =25
So the third terms is T(3) = 3^2 = 9

you mix (5)/(8)of a cup of wheat flour with 1 (3)/(4)cups of white flour. Do you have enough flour for a recipe that calls for 2

swat32

5/8+1 3/4
5/8+7/4(turned into improper fraction)
5/8+14/8=19/8=2 3/8
(Make sure they all have a common denominator so that u will be able to add)Then your answer is an improper fraction so u turn it in to a mixed number and 2 1/2 is the same as 2 4/8 and you have 2 3/8 therefore,
no you do not have enough flour you need 1/8 of a cup more.

The interior angles formed by the sides of a hexagon have measures that sum to 720°.

ira [324]

Answer:

F=140

Step-by-step explanation:

Remember that all angles will be able to add to 720 so you should get something like this:

130+120+110+x-20+x-60+x-40=720

Then solve for x to do this:

130+120+110+x-20+x-60+x-40=720

360-120+3x=720

3x+240=720

3x=480

x=480/3

x=160

With x=160, you can plug in to solve and find that F=140
