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

Lauren spent 3/5 of her money on a refrigerator. The refrigerator cost $756. How much money did she have left?
Lelechka [254]
Fractions are the part/whole.  We can set this up to be...

3/5 = 756
756 x5/3 = 1260.

if she had 1260 to begin with and spent 756, she would have 504.00 left.

AWARDING DOUBLE POINTS question in pic, will report anything other than the answer
mash [69]

Answer:

m∠R is 72°

Step-by-step explanation:

In the given figure

∵ ΔPQR ≅ ΔUVW

→ From congruency

∵ m∠P = m∠U

∵ m∠Q = m∠V

∴ m∠R = m∠W

∵ m∠R = (10x - 18)°

∵ m∠W = 8x°

∵ m∠R = m∠W

→ Equate their measures

∴ 10x - 18 = 8x

→ Add 18 to both sides

∵ 10x - 18 + 18 = 8x + 18

∴ 10x = 8x + 18

→ Subtract 8x from both sides

∴ 10x - 8x = 8x - 8x + 18

∴ 2x = 18

→ Divide both sides by 2 to find x

∴ x = 9

→ Substitute the value of x in the m∠R

∵ m∠R = 10(9) - 18

∴ m∠R = 90 - 18

∴ m∠R = 72°

∴ m∠R is 72°
