4 0

Answer:

There are 8 and 12 balloons for groups A and B, respectively.

Step-by-step explanation:

The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:

Group A

n_{A} = \frac{2}{2+3}\cdot (20)

n_{A} = 8

Group B

n_{B} = \frac{3}{2+3}\cdot (20)

n_{B} = 12

There are 8 and 12 balloons for groups A and B, respectively.

The formula below gives the Fahrenheit temperature F in terms of the Celsius temperature C.
Nostrana [21]
F=\dfrac{9}{5}C+32\\\\a.\ \dfrac{9}{5}C+32=F\ \ \ \ |-32\\\\\dfrac{9}{5}C=F-32\ \ \ |\cdot\dfrac{5}{9}\\\\C=\dfrac{5}{9}(F-32)


F=60\to C=\dfrac{5}{9}(60-31)=\dfrac{5}{9}\cdot29\approx16.1\\\\\boxed{60^oF\approx16.1^oC}


C=42\to F=\dfrac{9}{5}\cdot42+32=75.6+32=107.6\\\\\boxed{42^oC=107.6^oF}
