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 :)

SSSSS [86.1K]

Answer:640

Step-by-step explanation:

Since 15 out of every 75 fish are more than 30 cm long, the probability of finding a fish more than 30 cm is P(x > 30) = 15/75 = 1/5.

The probability of finding a fish 30 cm or less is P(x ≤ 30) = 1 - P(x > 30)

= 1 - 1/5

= (5 - 1)/5

= 4/5

Since we have 800 fish and the probability of finding a fish 30 cm or less is P(x ≤ 30) = 4/5, then the number of fish in the population that are 30 cm or less in length are 800 × P(x ≤ 30) = 800 × 4/5

= 160 × 4

= 640

So, 640 fish in the population are 30 cm or less in length

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Let's look at each option to which one is true with regard to the given functions on the graph.

The option that is correct is the option that shows where the graph of f(x) and g(x) intercepts or cut across each other.

Now, take a look at the graph, the line of both functions intercepts at x = -3. At this point, the value of f(-3) and g(-3) is equal to -4.

Therefore: f(-3) = g(-3)
