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 :)

A shape is made of 12 right triangles of equal size each right triangle has a base of 4 centimeters and a height a 5-cm what is
mart [117]

Answer:

120\ cm^2

Step-by-step explanation:

The area (A_t) of a triangle is equal to half the product of its length (L) because of its height (h).

A_t = 0.5h*L

The base of the triangles is L = 4\ cm

The height of the triangles is h = 5\ cm

Then the area of one of the triangles is:

A_t = 0.5(4)(5)\\A_t = 10\ cm^2

The figure is formed by 12 equal triangles, then the area of the figure (A_f) is:

A_f = 12(A_t)\\A_f = 12(10)\\A_f = 120\ cm^2
