Step-by-step explanation:
If a variables varies jointly, we can just divide it by the other variables in relation to it.
For example, since p variables jointly as q and square of r, then
where k is a constant
First, let find k. Substitute p= 200
q= 2, and r=3.
Now, since we know our constant, let find p.
Q is 5, and r is 2.

Answer:
700 or 960
Step-by-step explanation:
350x2=700
480x2=96
Answer:
$0.33
Step-by-step explanation:
If three packs cost 0.98, one pack costs about 0.33
This is not exact though. I rounded it to the nearest hundredth.
Step-by-step explanation:
- Since,in question 21 the trspezium is an isoseles tapizium
- therefore,9x-17=4x+28
- 5x=45
- x=9
- therefore q=9x-17
- =9*9-17
- =81-17
- q=64
- therefore 2t=360-128(since its isoseles triangle therefore adjacent base angles are equal)
- 2t=23
- t=116
- 2(K+M)=360
- 2(3x+16 + 11x-18)=360
- 2(14x-2)=360
- 28x-4=360
- 28x=364
- x=13
- J=K
- Isoleses angles are equal
- 3x+16=J
- 39+16=J
- J=55
- Bd=Ec (Congeruent sides of congurent trisnle are equal,BED~=CDE)
- 8x-27=2x+33
- 6x=60
- x=10
- Therefore,Bd=8x-27
- Bd=80-27
- Bd=53
