Answer: Using more heat
Step-by-step explanation: it emits more carbon dioxide. Everything else conserves it
Answer:
146 whistles
Step-by-step explanation:
First, convert 122 feet to inches, by multiplying it by 12
122(12)
= 1464
Divide this by 10 to find how many whistles he can make
1464/10
= 146.4
Since we can only have a whole number of whistles, we have to round down to 146.
So, he can make 146 whistles
Answer:
y=x+3
Step-by-step explanation:
The equation "y=x+3" cannot be written in the form y=kx because <u><em>the form </em></u><u><em>doesn't use addition</em></u><u><em> as a basic operation.</em></u> Let's try verifying the choices:
y=x is possible<em> </em>if the value of k is 1, provided that both y and x are of the same value.
y/2=x is possible because y=2x, provided that 2 is the value of k.
y=-1/10x is possible because -1/10 is the value of k. This is just the same with y=kx.
Answer:
r=2.808cm h = 100cm
then we get volume of cylinder that is 2744 As explained below
Step-by-step explanation:
Volume of cylinder = πr²h
Surface area of cylinder = 2πrh +πr² (1)
h= 2744 /πr²
put value oh h in equation (1)
Area =[2πr] 2744 /πr²
=[5488/r +πr²]
dA/dx=0
i.e 2πr=5488/r²
Solving this r.r= ∛5488/2π
=2.808
taking second derivation we get 100
