Answer:

The correct option is B) 32,808.4 ft

Step-by-step explanation:

Consider the provided information.

We need to find that how many feet are in 10 km.

1 km = 3280.84 feet

Now, multiply both the sides by 10.

1×10 km = 3280.84×10 feet

10 km = 32,808.4 feet

Hence, the correct option is B) 32,808.4 ft

Find the value of "a" if you knew the perimeter was 47 meters long. Here is the experssion 7a-2
Aneli [31]
That isn’t right I don’t think, if a was 47 then it would be wayyyy bigger of a number. You are finding how 7a-2 is 47. First add 2 to both sides making it 7a=49

Cynthia Bech want to buy a rug for a room that i 20 ft wide and ft long. She want to leave a uniform trip of 29 floor around the
Hoochie [10]

On solving the question, we got that - The dimensions of the rug should be 18 feet and 24 feet

<h3>What is area of rectangle?</h3>

By multiplying the rectangle's length by its breadth, we may get its area.

Equiangular quadrilaterals, like rectangles, are known in this way. This is so because a rectangle is a four-sided quadrilateral shape with parallel sides that are equal to one another and four corners with 90o angles. Rectangles are sometimes known as equiangular quadrilaterals since all of its angles are 90 degrees.

the parameters provided;

The room is 20 feet by 26 feet in size.

432 feet2 is the largest area rug she can afford.

If the floor will be a uniform stripe around the rug, then each dimension should have its uniform extra length of floor =  (y).

Area = Length X Width\\432 = ((20=y) X (26-y)\\432 = 520 - 20y - 26y + y^2\\y^2 - 46y+88=0\\

here, a= 1, b= -46, c =88

y = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a} \\\\

y = \frac{-(-46) +/- \sqrt{(-46)^2 - 4X1X88} } {2} \\\\y = 44 \\or\\ y =  2

Therefore, Length = 20-2 = 18 ft

and width = 26-2 = 24ft

Find the area of the shaded region given the radius of each circle is 4. Answer in exact form is preferred.
larisa [96]

In each circle, we have a sector that subtends an angle of 270 deg at the center, with a radius of 4

We can obtain the area of each sector as :

\begin{gathered} \text{Area of sector = }\frac{\theta}{360^0}\text{ }\times\text{ }\pi r^2 \\ =\text{ }\frac{270^0}{360^0}\text{ }\times\text{ }\pi\text{ }\times4^2 \\ =\text{ 37.7 square units} \end{gathered}

Given that there are 4 of such sectors, we have:

\begin{gathered} \text{Area of shaded region = 4 }\times\text{ 37.7} \\ =\text{ }150.8\text{ square units} \\ =\text{ 151 square units} \end{gathered}

Answer = 151 square units

Are 12/20 and 22/30 equivalent fractions? Why or why not?
jek_recluse [69]
Yes! It is equivalent because you are pretty much multiplying 12/20 by 10 which equals 22/30.
