Serjik [45]4 years ago

Answer:

Step-by-step explanation:

exponent rule : a^b * a^c = a^(b + c).....so when they have the same base, keep the base and add the exponents. And just so you know, that first lone 3 has an exponent of 1.

3^1 * 3^2 * 3^3 = 3^(1 + 2 + 3) = 3^6 = 729

or this way...

3 * 3^2 * 3^3 = 3 * 9 * 27 = 729

What is the value of b?
Evgen [1.6K]

Answer:

30

b =   \sqrt{ {c}^{2}  -  {a}^{ {2} } }

b =  \sqrt{ {34}^{2}  -  {16}^{2} }

b = \sqrt{1156 - 256}

b =  \sqrt{900}

b =  30

Frank got a gift for his sister and put it in a shoebox.
Leona [35]

Answer:

The correct answer is option C.

Step-by-step explanation:

Length of shoe box = l = 11 inches

Width of the shoes box = w = 6 inches

Height of the shoe box = h = 5 inches

Wrapping paper required t cover the shoe box will be equal to the total surface area of the shoe box.

Shoe box = Cuboid

Total surface area of the cuboid = 2(lw+wh+hl)

Total surface area of shoe box : T

T=2\times (11 inch\times 6 inch+6 inch\times 5 inch+5 inch\times 11 inch)

=T = 302 inch^2

Frank will need 302 square inches of wrapping paper to cover the shoe box.

Two semicircles are placed in a rectangle, as shown below. The length of the rectangle is 48. And do not round your answer. Be s
ANTONII [103]

Answer and Step-by-step explanation:

Firstly, we should note that the rectangle given is a square. This is because, the diameter of the semicircle is the same horizontally and vertically

Since the length of the rectangle is 48, it means the radius of each semi circle is 24.

The area of one semicircle will be:

0.5πr²

Where r = 24 and π = 3.14

0.5 x 3.14 x 24 = 37.68 square units

Since we have two semicircles, then the area of both will be:

37.68 x 2 = 75.36 square units.

To find the area shaded portion. Since I cannot see the diagram, there are two possibilities. If the shaded potion is just the two semicircles, then the area is 75.36 square units. But if the shaded portion is what ever remains after taking out the semicircles, then the area would be:

48² – 75.36 = 2133.64 square units.
