29).  The 'six' is the same as (6 x 5) = 30 fifths.
So  six and three fifths = (30 + 3) fifths  =  thirty-three fifths.

30).  The 'eight' is the same as (8 x 6) = 48 sixths.
So  eight and five sixths = (48 + 5) fifths=  fifty-three sixths.

31).  Twenty-seven of the thirds are the same as  (27/9)  = 3 .
That leaves a remainder of 2 thirds.
So  twenty-nine thirds are the same as  3 and 2/3 .

32).  Thirty-two of the fourths are the same as  (32/4) = 8 .
That leaves a remainder of one fourth.
So  thirty-three fourths are the same as  4 and 1/4 .

The number of significant figures in the numbers are

  • 100 cm = 1 significant digit
  • 0.006700 cm = 2 significant digits
  • 450. cm = 3 significant digits

<h3>How to determine the number of significant figures in the following numbers?</h3>

As a general rule, the zeros before and after the non-zero figures are not significant.

Using the above rule, we have:

  • 100 cm = 1 significant digit
  • 0.006700 cm = 2 significant digits
  • 450. cm = 3 significant digits

<h3>How to round the following numbers to the correct number of significant figures</h3>

Using the above rule in (a), we have:

  • 123g to show 1 sig fig = 100 g
  • 0.19851m to show 2 sig figs = 0.2 m
  • 0.0057034L to show 3 sig figs = 0.005703 L

<h3>How to report the following answers with correct significant figures</h3>

We have:

(12.93cm) x (2.34cm) x (8cm) = 242.05 cm^3 because 12.93 has 4 significant figures

67.0m / 2.18s = 30.7 m/s because 2.18 has 3 significant figures

<h3>How to convert the following metric to metric</h3>

450mL = 0.45 L

because 1 mL = 0.001 L

2.3 dm = 0.00023 km

because 1 dm = 0.0001 km

0.120cg = 1.2 mg

because 1 cg = 10 mg

6700L = 670000 cL

because 1 L = 100 cL

<h3>How to convert the following metric</h3>

a. 2.34miles = 3.76 km (1mile = 1.61km) -- given

b. 5.3ft = 161.544 cm(2.54cm = 1 in)

Because 1 ft = 30.48 cm

Hey! Leonardo's mother gave him 5 bags with 6 flower bulbs in each bag to plant. He has planted all except 3 bulbs. How many flo
Solnce55 [7]
Ok so If I am understanding the question correctly, you will multiply 5 x 6 = 30 so there are 30 Bulbs. So all except 3 were planted. So then you will subtract 3 from 30 like this 30-3=27. That is your answer. Just take a deep breath Math looks a lot harder than it really is.

Suppose that the function fis defined on the interval (-2,2) as follows. <br>​find f(-1) f(0.5) f(1)
frosja888 [35]

Answer:

Step-by-step explanation:

Hello,

-1 <= -1 < 0

so f(-1)=-1

0 <= 0.5 < 1

so f(0.5)=0

1 <= 1 < 2

so f(1)=1

Thank you.
