Answer:

I honestly was having the worst time trying to solve this sorry :(, for real idk if any of these are right

i got 2 answers; 1st: ≈0.5 mph

the 2nd; 2 mph

Step-by-step explanation:

Speed = \frac{Distance}{Time}

2/3 miles = 3520 feet

1/3 hours = 20 minutes

------Make a proportion-----

\frac{3520ft}{20min} = \frac{1 mi=5280 ft}{1hr = 60min}

cross multiply------

3520 * 60 = 211200

5280 * 20 = 105600

Divide \frac{211200}{105600}= 2

---(this is where i got confused cuz 2 doesn't make any sense)--

If you flip them, \frac{105600}{211200}=0.5 which makes more sense

hope i helped :(

Answer:

42) 254.47 ft²

43) 56 pendants

Step-by-step explanation:

42)

The radius of a circle is equal to half of its diameter.

Diameter = 18 feet

Radius = Diameter ÷ 2 = 18 ÷ 2 = 9 feet

Area of a circle = π r^{2}

Substitute in known value of r

Area = π 9^{2}

Substitute in pi

Area = 3.14 * 9^{2}

Solve exponent

Area = 3.14159265359 * 81

Area = 254.4690049408

(Rounds to 254.47)

254.47 ft²

43)

1\frac{1}{2} = 1.5 ounces per pendant

3 pieces of silver:

1\frac{7}{8}  pounds

14 ounces

2\frac{1}{2} pounds

Convert to improper fractions (1 lb = 16 ounces)

\frac{15}{8}  pounds

\frac{14}{16}  pounds

\frac{5}{2} pounds

Find a common denominator for the fractions

\frac{30}{16} pounds

\frac{14}{16} pounds

\frac{40}{16} pounds

Add

\frac{30}{16} + \frac{14}{16}  + \frac{40}{16}  

\frac{84}{16}  pounds

Find how many pendants can be made out of this amount

\frac{84}{16}  pounds

Convert back to ounces (1 lb = 16 ounces)

84 ounces

Amount to make one pendant:

1\frac{1}{2} ounces

Convert to decimal

1.5 ounces

Divide 84 by amount of silver per pendant

84 ÷ 1.5

56

The maximum number the pendants that the manufacturer can make is 56

Hope this helps :)
