Your doctor told you to eat 25 grams of fiber each day.
babymother [125]
If you divide 4/25 it equals 16%. Or another way you can do it is you multiply 25 by 4 to get 100 then just multiply 4 by 4 also and it gets you 16/100 which equals 16%.

IJ is a midsegment of FGH. IJ=10, FH=8, and GH=14.Find the perimeter of ijh
never [62]

Answer:

Perimeter = 21

Step-by-step explanation:

Given

IJ = 10

FH = 8

GH =14

Required

Calculate the perimeter of IJH

<em>See attachment for illustration</em>

From the attachment,

I = mid of FH.

So:

HI = \frac{1}{2} * FH

HI = \frac{1}{2} * 8

HI = 4

J = mid of GH.

So:

HJ = \frac{1}{2} * GH

HJ = \frac{1}{2} * 14

HJ = 7

Perimeter IJH is then calculated as:

Perimeter = HI + HJ + IJ

Perimeter = 4 + 7 + 10

Perimeter = 21
