Find the approximate side length of a square game board with an area of 105 in2.
aleksley [76]

Answer:

Rounded to the nearest inch: 10

Rounded to the nearest tenth: 10.2

Rounded to the nearest hundredth: 10.25

Step-by-step explanation:

To find the area of a square, we multiply the side length by itself, or in other words, SQUARE the side length!

A=s^2

We are given the area, so plugging that into our equation looks like this:

105=s^2

To eliminate the exponent, take the square root of both sides of the equation!

\sqrt{105}=s

From here, there are a few paths to take, depending on what your teacher is looking for. I will evaluate the approximate of the square root by finding the nearest perfect squares.

The nearest perfect square less than √105 is √100, and the nearest perfect square greater than √105 is √121.

105 is closer to 100 than to 121, so √105 is closer to √100.

√100 is equal to 10, so the √105 is approximately 10 inches!

Using a calculator to check:

\sqrt{105}=10.247 inches

Please help fast!! Katrina has $3.60 worth of nickels and dimes. She has 46 coins in total. How many nickels and dimes does she
Igoryamba

Answer:

20 nickels and 26 dimes

Step-by-step explanation:

  • She has $3.60 in nickels and dimes
  • a nickel is $0.05 and a dime is $0.10
  • let n be the number of nickels and d be the number of dimes
  • thus the first equation is 3.6 = 0.05n +0.1d
  • If she has 46 coins then n + d = 46
  • then n = 46 - d
  • sub n = 46 - d into 3.6 = 0.05n +0.1d
  • 3.6 = 0.05(46 - d) + 0.1d
  • 3.6 = 2.3 -0.05d+0.1d
  • 1.3 = 0.05d
  • 26 = d
  • sub d = 26 into n+d=46
  • n+26=46
  • n=20
  • Check by subbing n=20 and d=26 into 0.05n +0.1d
  • 0.05(20) +0.1(26)
  • 1+2.6 = 3.6

A regular hexagon has an apothem of 14.7 inches and a perimeter of 101.8 inches. What is the area of the hexagon?
Neporo4naja [7]

<u>Answer</u>

748.23 in²


<u>Explanation</u>

Apothem a line from the centre of a regular polygon at right angles to any of its sides. This can be said to be the height of the triangle in a polygon.

The base of the  hexagon = 101.8 ÷ 6

                                            = 19.96666..

                                            = 19.9667 inches

Area of the  hexagon = 1/2 × height × base length × 6

                                     = 1/2 × 14.7 × 19.9667 × 6

                                      = 748.23 in²
