Can someone help me find the constant? L varies directly as h; when l=112, h=-16
Answers
that means that when when L goes up, h also increases, when L decreases, h also decreases
so the constant is k where k=y/x
in this case it is k=L/h so subsitute
L=112
h=-16
k=L/h
k=112/-16
k=-7
the constant is -7
L = kh
where k is constant
In terms of k,
k = L/h
Given L = 112 and h = 16
k = 112/-16 = -7

45/2=22.5 minutes
Now you can start finding how many hours it would take to bake 8 dozen.
22.5 * 8 = 180.
180/60=3
Your answer is 3 hours!
2 8
--- -> ----
45 x
see this is simple now we just have to find x
what do we multiply too 2 to get 8?
4 right?
so keeping that in mind we do the same thing to the denominator(the 45)
sooooo 45 x 4 = 180
now this is in minuets and since there are 60 minutes in one hour lets
divide 180/60 = 3
see how simple this one was?
so it would take you three hours to make 8 dozen cupcakes

the powers of 2 that are in the range 2 through 1,000 are 2,4,8,16,32,64,128,256,&512 .what does that mean and it said find all the powers of 3 that are in range 3 through 1,000 im so confused

Answer:
- the powers of 2 that are in the range 2 through 1,000 are 2,4,8,16,32,64,128,256,&512.
" This means that we are asked to find the value of for each n belonging to natural numbers.
Now we will stop our approximation when the value exceeds 1000.
i.e. the range is from 2-1000 ".
since the next number after 512 is 512×2=1024 which exceeds 1000. hence our successive approximation will stop at 512.
- similarly for the powers of 3 i.e.
We will start writing our approximation and stop when it will exceed 1000.
i.e.
i.e. the sequence is: 3,9,27,81,243,729.
We stopped at 729 because the next number in the series would be:
which exceeds 1000.
So 3 to the 1st power is 3 = 3
3 to the 2nd power is 3X3 = 9
3 to the 3rd power is 3X3X3 = 27
And so on... Hope I helped!
b) An apple granola bar
Answers
54 will be your total.
A peanut butter granola will be 14/54 which when you simplify it will be 7/27. Since there is 14 peanut butter granola it will be on the denominator which is the part.
A apple granola will be 12/54 which when you simplify it will be 2/9. The part of the apple granola is 12.
The number is a fraction.
