What’s 48 rounded to the nearest ten

50

Step-by-step explanation:

When you around to the nearest ten, you look at the ones digit, which in this case, is 8. Since that is 5 and above, you would have to round the 4 in the tens digit up to 5, resulting in 50.

10000

step-by-step explanation: divide by 2,

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.
