Hi, Which of these percentages is closest in value to 7/9

1 answer:

4 0

To find a percentage, you need to divide 7 by 9 to find out what 7/9 is.
It turns out to be 0.777 repeating.
To find a percentage, you need to move the decimal place over by two to the right, so 7/9 is equals to 77.77%.
If you round that, then 77.77% is closest to 78%.

Hope this helps!

If LK=MK, LK=7x-10,KN=x+3, MN=9x-11 and KJ=28 find LJ

beks73 [17]

Suppose J, K, L, M, N are points on the same line.

MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14

Since LK = MK and LK = 7x - 10, then

7x - 10 = 8x - 14

8x - 7x = -10 + 14

x = 4

LJ = MK + KJ

MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18

LJ = 18 + 28 = 46

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the trian

mart [117]

Answer:

The area is 11317.51

Step-by-step explanation:

The sum of 2 sides must be less than the third side (largest side) for a triangle to be formed.

b+c<a

133+174 < 240

A triangle can be formed

To use Herons formula for the area

We find S = 1/2( a+b+c)

= 1/2(240+133+174)

= 1/2 (547)

= 273.5

Area = sqrt( S (S-a) (S-b)(S-c))

sqrt((273.5 ) (273.5 -240) (273.5-133) (273.5-174))

sqrt((273.5)(33.5) (140.5) (99.5))

sqrt(128085964.4)

11317.50699

The area is 11317.51
