Math question C= 5
9
(F−32)
The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?
A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
5
9
degree Celsius.
A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of
5
9
degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only

D) I and II only

Explanation:

The equation which related Fahrenheit to Celsius is given as:

For F = 32, C = 0

For F = 33, C = 5/9

For F = 34, C = (2)(5/9)

Hence, Statement (I) is correct

For C = 0, F = 32

For C = 1

As F₂ - F₁ = 33.8 - 32 = 1.8 , Statement (II) is correct

As it contradicts with Statement (I), and Statement (I) was found correct, Statement (III) is incorrect

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
