What is the difference in Fahrenheit degrees between a temperature of 0C and a temperature of 15C?

slamgirl [31]

Answer:

$27^{\circ}F$

Step-by-step explanation:

Use formula

$F=1.8C+32$

to convert Celsius to Fahrenheit.

When $C_1=0^{\circ}C,$ then

$F_1=1.8\cdot 0+32\\ \\F_1=32^{\circ}F$

When $C_2=15^{\circ}C,$ then

$F_2=1.8\cdot 15+32\\ \\F_2=27+32=59^{\circ}F$

Difference:

$F_2-F_1=59^{\circ}F-32^{\circ}F=27^{\circ}F$

Given AB=10cm, CD=11cm, and AD=39cm, find the length of BC

liraira [26]

<u>Answer:</u>

BC = 18 cm

<u>Step-by-step explanation:</u>

As we can see from the diagram:

AB + BC + CD = AD

⇒ 10 cm + BC + 11 cm = 39 cm

⇒ BC + 21 cm = 39 cm

⇒ BC = 39 cm - 21 cm

⇒ BC = 18 cm
