Let's assume
boiling point is y
altitude is x
we are given
This relationship between altitude and boiling point is linear
At an altitude of 1000 feet, water boils at 210°F
so, first point is (1000,210)
so, x1=1000 , y1=210
At an altitude of 3000 feet, water boils at 206°F
so, second point is (3000,206)
so, x2=3000,y2=206
now, we can find slope

now, we can plug values


now, we can use point slope form of line

so, we can plug it

so, point slope form of line is

now, we can plug x=8000
and then we can solve for y


So,
the boiling point of water at an altitude of 8000 feet is 196°F..........Answer
Answer:
the no of puppets that could be made with his string is 21
Step-by-step explanation:
Given that
There is 7 yards
And, it needs one -third of string for each of his puppets
= 7 × 3
= 21 puppets
We simply multiply the 7 yards with the 3 so that the no of puppets could come
hence, the no of puppets that could be made with his string is 21
12x + 24y < = 240
** because 2 hrs and 120 minutes = 240 minutes
Answer:
10
Step-by-step explanation:
√81 = 9 (9+9-4*2)
4 * 2 = 8 (9+9-8)
9 + 9 = 18 (18 - 8)
18 - 8 = 10
Answer:
see explanation
Step-by-step explanation:
A recursive rule allows us to find the term in a sequence from the previous term.
From the given geometric sequence find r the common ratio
r =
=
= - 4
Hence recursive rule is
= - 4
