Answer:

Step-by-step explanation:

1)

A. 2 meters to centimeters

1 m = 100 cm

2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2

B)108 centimeters to meters

100 cm =1 m

1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m

C)2.49 meters to centimeters

1 m = 100 cm

2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm

D)50 centimeters to meters

100 cm = 1m

1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m

E)6.3 meters to centimeters

1 m = 100 cm

6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630  cm

F)7 centimeters to meters

100 cm = 1 m

1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m

2)

a)4 meters to millimeters

1 m = 1000 mm

4 m = 4000 = 4 \times 10^3 mm

b)1.7 meters to millimeters

1 m = 1000 mm

1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm

Let s represent a false statement, let p represent a true statement, and let r represent a false statement. Find the truth value
kondaur [170]
<h3>Answer:  false</h3>

Work Shown:

s = false

p = true

r = false

-p = false, which is the opposite of statement p

s or -p = false or false = false

The result of an 'or' operation is false only when both parts are false; otherwise, it is true

(s or -p) or r = false or false = false

(s or -p) or r = false

kumpel [21]
Answer:
x = 10

Explanation:
Note the following rules before we begin:
2 ln(a) = ln (a²)
ln (a) + ln (b) = ln (ab)

Now, for the given:
ln(20) + ln(5) = 2 ln(x)
ln(20*5) = ln(x²)
ln(100) = ln(x²)

This means that:
100 = x²
Therefore:
either x = 10 .........> acceped
or x = -10 .........> rejected as no negatives are allowed within ln functions

Hope this helps :)
