A weather station reported 90% of the days in a 30-day period had measurable snowfall. How many of these days received measurable snowfall?

27 days.

Step-by-step explanation:

Find 1% out of the 30-day period.

100% = 30 days

1% = 30 ÷ 100 = 0.30

Now find the percentage reported that had measurable snowfall which is 90%.

90% = 0.30 x 90 = 27

Out of the 30-day period, only 27 days received measurable snow.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
