I'll be solving this by using the Triangle Inequality Theorem: a+b>c, a+c>b, and b+c>a

A.<u> </u><u>54 mm, 65 mm, and 120 mm:</u> 54=a, 65=b, 120=c and 54 + 65 > 120 so it's false.

B. <u>12 in, 43 in, and 56 in:</u> 12=a, 43=b, 56=c, 12 + 43 > 56 so false

C. <u>16 ft, 24 ft, and 42 ft:</u> 24=a, 16=b, 42=c, but 16 + 24 > 60 so it's false

D. <u>21 cm, 41 cm, and 60 cm:</u> 21=a, 41=b, 60=c

21 + 41 > 60

21 + 60 > 41

41 + 60 > 21

It equals all three formulas so D is the right answer.

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

ch4aika [34]
3,6,12...

this is a geometric sequence with a common ratio of 2. That means u multiply each term by 2 to find the next term.

start with 3
3 * 2 = 6
6 * 2 = 12
12 * 2 = 24...this would be ur next term

so ur answer is : multiply by 2

I have a series of questions
alexgriva [62]

Answer:

  0.4, 0.004, 0.004

Step-by-step explanation:

The "what" in each case is found by dividing the target value by 10. That is accomplished by moving the decimal point one place to the left.

4/10 = 0.4   ⇒   10 times 0.4 = 4

0.04 and .04 are exactly the same value, so the last two on your list are the same:

0.04/10 = 0.004   ⇒   10 times .004 = 0.04
