I think you shouldn't memorize any formula to solve it. But you should know that on the fahrenheit thermometer freezing point is 32 and the boiling point is 212. And in celcius, it is 0 and 100. So we can make the inference that changing 100 units in celcius corresponds to a change of 180 units in fahrenheit. Thus, we should ask that if celcius increase from 0 to 200, what would happen to fahrenheit.
Basic math:
While celcius increase 100, fahrenheit increase 180,
While celcius increase 200, fahreinheit increase 360.
And you shouldn't forget that fahrenheit's freezing point is 32.
32+increase(360)=392
Answer:
2
Step-by-step explanation:
We can find the slope of the line by using the slope formula
m = ( y2-y1)/(x2-x1) where ( x1,y1) and (x2,y1) are points on the line
Using the points (0,-4) and (2,0)
m = ( 0 - -4)/ ( 2 - 0)
= ( 0+4)/( 2-0)
= 4/2
= 2
Use combination
probability = (11C1 + 7C1)/28C2
probability = (11+7)/378
probability = 18/378
probability = 1/21
-8n-25-3n then you would need too add like terms and it'd be -11n-25
Answer:
48cm^2
Step-by-step explanation:
We can break the composite figure into two pieces.
We take the bottom rectangle and determine its area
The figure is 10 cm by 2 cm
A = 10*2 = 20cm^2
The height of the vertical rectangle is 9 cm -2 cm = 7 cm
The width is 10 cm - 6 cm = 4 cm
The figure is 7 cm cm by 4 cm
A = 7*4 = 28cm^2
The total area is the sum of the two areas
20 cm^2 + 28 cm^2 = 48 cm^2
