If Melanie get's 4.10$, then Jacob get's 20.50$.
We can divide to get the unit rate:
20.50 ÷ 4.10 = 5
This means that if Jacob gets 5$, then Melanie will get 1$.
So in this case, Melanie get's 1$.
Answer:
20°C
Step-by-step explanation:
Quantity if heat energy supplied is expressed as;
Q = mcΔt
m is the mass = 3kg
Δt is the temperature rise
Q = 5400J
c = 900 J/kg °C
Substitute
5400 = 3(90)Δt
5400 = 270Δt
Δt = 5400/270
Δt = 20°C
Hence the temperature rise is 20°C
The solution would be like this for this specific problem:
The correct sequence of operations when solving
negative one over five (x − 25) = 7 would be multiply each side by −5, and adding
25 to each side.
Perimeter (P)= 2Length (L) +2Width (W)
P=2L + 2W
P=(2y)+(3y-5)
P=5y-5
A. 5y-5
