Question

3) Calculate the following degi selle Celsius temporato ste to
degoce
Fahrenhani.
9 40°c, b 300
a 40°C​

Answer 1

Answer:

the formula to find Fahrenheit from degree celsius = 9/5+32

(a,) given, 40 degree Celsius = 40×9/5+32

= 8×9+32

= 72+32

= 104 F

(b) given, 300 degree Celsius = 300×9/5+32

= 60×9+32

= 540+32

= 572 F

# given, 940 degree Celsius =940×9/5+32

= 188×9+32

= 1692+32

= 1724 F

hope it is helpful for you .

so please follow me ,thank me and mark me as brilliant

Answer 2

Correct Question

Calculate the following temperature from Celcius to Fahrenheit.

a) 940° C ; b) 300° C ; c) 40°C

To Find

Celcius :arrow_right: Fahrenheit

Formula used

$(^\circ C \times \dfrac{9}{5} ) + 32 = ^\circ F$

Solution

step-by-step explanation:

a) 940°C

$\bigg(940 \times \dfrac{9}{5}\bigg ) + 32$

$\bigg(\cancel{940}\times \dfrac{9} {\cancel{5}}\bigg) + 32$

$\bigg( 188 \times 9\bigg) + 32$

$1692 + 32 \\ = {1724}^{\circ} F$

b) 300°C

$\bigg(300\times \dfrac{9}{5}\bigg ) + 32$

$\bigg(\cancel{300}\times \dfrac{9} {\cancel{5}}\bigg ) + 32$

$\bigg( 60\times 9\bigg)+ 32$

$540 + 32 \\ = {572}^{\circ} F$

c) 40° C

$\bigg(40 \times \dfrac{9}{5}\bigg ) + 32$

$\bigg(\cancel{40}\times \dfrac{9}{\cancel{5}}\bigg ) + 32$

$\bigg( 8 \times 9\bigg)+ 32$

$72 + 32 \\ = 104° F$

Required Answer

a) 940° C = 1724 °F

b) 300° C = 572°F

c) 40°C = 104°F
