Answer:
see below
Step-by-step explanation:
As with many multiple-choice questions, the appropriate choices can often be determined with a simple test. Here, you only need to look at the values of the constants. (Those are ringed in blue.)
Answer:4.5y
Step-by-step explanation: you have to multiply 15 times 0.3 and u get 4.5y
Answer:
75°C = 5h
Step-by-step explanation :
1. Make sure your mind is fresh and that you understand each step before reading
2. 24 hours is equal to 360°C
3. so now lets break up the hours. We can do this by choosing a simple degree that was given in the diagram. For example "Watching tv".
Tip : when choosing one of the degrees , ( i mean one of the choices like watching tv, playing and sleeping) , try choosing the simplest one , which has a simple number and a multiple of 360.
so now you want to know how many hours is 60 equal to .
= 360 ÷ 60 = 60 (this is to make sure the number is a multiple and will not be a decimal )
= 24 ÷ 6 = 4
this means Ali spend 4 hours watching tv
and by doubling that you get 60°C = 4h
the amount of time he slept 120°C = 8h
and you keep playing with the numbers like that
so for playing
60°C = 4h
divide by 4 15°C = 1h
× by 5 75°C = 5h
this means ali spends 5h playing , 8h sleeping, 4h watching tv and 7 h studding
OK here is it
y=mx+c is the basic equation for a linear graph
If u plot the values above on a graph u'll get a straight line so
m is the slope or if they havent taught u slope is amount of y increases or decreases with respect to x. and C is the intercept or in other words where the graph or the system given above meets the y axis.
the above info is quite unnecessary but important to know
so putting the values into the equation
Youll get the values of m and C so
m=-1/2 and C=11
the relation between x and y is
y=(-1/2)x+11
put the values from the table ull get the right answer
