Answer:
<h2> Assuming your friend said the temperature over there was 68 degrees Fahrenheit in degrees C it would be 20 °C</h2>
Step-by-step explanation:
The question is not complete, as the information, your best friend in Europe about the temperature over there is missing, nevertheless, we can proceed with this problem by plugging in an assumed temperature.
The expression for conversion from degrees F to degrees C is given as
T(°C) = (T(°F) - 32) × 5/9
Now say temperature your friend e-mailed you is 68 degrees Fahrenheit (you can as well plug in your own value)
T(°C) = (68°F - 32) × 5/9
T(°C) = (36) × 5/9
T(°C) = 180/9 = 20 °C
T(°C) = 20 °C
39x3=30x3+9x3
117=90+27
117=117
39x3=30+9x3
117=30+27
117=57
39x3=300x3+9x3
117=900+27
117=927
39x3=30x3+9
117=90+9
117=99
So the first one is correct.

The geometric rule for the nth term of the geometric sequence for which a1 =−6 and a5=−486 is -6 × 3^(n - 1)
<h3>The nth term of a geometric sequence</h3>
First term, a1 = -6
Fifth term, a5 = -486
a5 = ar^(n - 1)
-486 = -6 × r^(5-1)
-486 = -6r⁴
r⁴ = -486 / 6
r⁴ = 81
r = 4√81
r = 3
Geometric rule:
nth term = ar^(n-1)
nth term = -6 × 3^(n - 1)

7.76 to one decimal place
= 7.8
We are looking at one decimal place, in this case the number 7 after the decimal place next to 6. Any number above 5 rounds up the number in front of it. 6 is above 5 so it changes the 7 to an 8.
