Round 5.6 to the nearest whole number.

6

Step-by-step explanation:

- First, locate the tenths digit of the number you are rounding. The tenths digit of a number is the digit directly to the right of the decimal point.

In this  example, the tenths digit of 5.6 is 6.

- Next, determine whether the tenths digit is less than 5. This will determine whether how you round your number up or down. If the tenths digit is 5 or greater, you round up. If the tenths digit is less than 5 -- including 0 -- you round down.

When the tenths digit is 5 or greater, you round up. This means you add 1 to the ones digit of your number, the digit directly to the left of the decimal point.

In our example 6 is greater than 5, so you have to round up 5.6 to 6.

answer: 590

step-by-step explanation:

(a) common ratio in the given sequence is, 3

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
