Answer:

7) refer to d=rt triangle so answer is t= d/r

8) rearrange by dividing so it should be PV/nR = T

9) move 5r to  other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2

10) multiply both side by b/1 so b got cancel on left side

right side become c(b/1) which is same as cb

then you divide both side by c to isolate b on the right side

final answer is a/c=b

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

Name the sets of numbers to which -7/9 belongs
Arlecino [84]
Ok
the sets are
natural numbers (or counting numbers), this is like 1,2,3,4,5 etc

whole numbers, this is including 0, so 0,1,2,3,4,5,6 etc

integers, this includes the previoius set and negatives, so -3,-2,-1,0,1,2,3,4,5 etc

rational numbers, this is the set of numbers that can be written in form a/b where b≠0, so all integers can be written like this, like example -3=-3/1, so -7/9 belongs here



-7/9 goes in the rational set
