Answer:
11. -8-4(3+5p) = -180
or, -8-4×3-4× 5p= -180
or, -8-12+20p=-180
or -8-12+180= -20p
or, 160= -20p
or,p= - 160/20
:. p= 8
Step-by-step explanation:
we can multiply small brackets then we can do add and subtract then we can get the value of p
Answer:
area = 5220 in²
Step-by-step explanation:
It's a little difficult to ensure accuracy without a diagram of the net, but from what you have said, the net appears to comprise of:
- 2 rectangles: 35 x 24
- 2 rectangles: 24 x 30
- 2 rectangles: 35 x 30
Therefore, the total area of the net is:
⇒ area = 2(35 x 24) + 2(24 x 30) + 2(35 x 30)
⇒ area = 5220 in²
(-1,0) has the same x value as (-1,2)
Answer:
=5
Step-by-step explanation:
Given that an experimenter is studying the effects of temperture, pressure, and type of catalyst on yield from a certain chemical reaction. Three different temperatures, four different pressures, and five different catalysts are under consideration.
a) Experimental runs possible if use of single temperature, pressure and catalyst is there = no of temperatures x no of pressures x no of catalysts
= b) Here pressure and temperature have no choice as lowest is selected.
no of methods = no of catalysts x 1 x1
= 5
