How much heat is necessary to melt 56.72 grams of substance y from solid phase at 15 degrees celsius to liquid at the same temperature? melting point of substance y = 15 degrees celsius; δhvaporization = 2.83 j/mol; δhfusion = 5.51 j/mol; mwsubstance y = 14.77 g/mol.

answer4 to the second power is 16

and 4 to the third power is 64,

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

step-by-step explanation:

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
