If the length of the legs of a right triangle are 5 m and 7 m, what is the length of the hypotenuse?
irakobra [83]

Answer:

c = 8.60232526704263

c \approx8.6

Step-by-step explanation:

{c}^{2}  =  {a}^{2}  +  {b}^{2}

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

c =  \sqrt{ {5}^{2}  +  {7}^{2} }

c =  \sqrt{25 + 49}

c =  \sqrt{74}

c = 8.60232526704263

c \approx8.6

the perimeter of a rectangular garden is 84 feet. write and solve the system of equations that can be used to find the dimension
scoray [572]

Answer:

The length is 22.5 and the width is 19.5

Step-by-step explanation:

          2L + 2W = P

                     \/

          2L + 2W = 84

                     \/

W + 3 + W + 3 + W + W= 84

                     \/

          4W + 6 = 84

                     \/

                4W = 78

                     \/

     W = 19.5      L = 19.5 + 3 = 22.5

I hope this helps, have a nice day! :D

Write and solve an equation to find the value of X
Mumz [18]
Angles on a straight line add up to 180 degrees so

45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left

3x = 135
Then divide both sides by 3
x = 45

Answer is X = 45

The product of two positive integers is 176. One number is 5 more than the other. Find the smaller number.
svlad2 [7]

Hello from MrBillDoesMath!

Answer:

11



Discussion:

Let "n" be the smaller number. Then

n * (n+5) = 176.


My first reaction to this problem was to factor 176 in my head. That's  176 = 16 * 11 and 16 is 5 more than 11. So that's the solution!.... Now let's solve it using the brute force approach:

n(n+5) = 176                 =>

n^2 + 5n - 176 = 0       => use the quadratic formula


n =     ( -5 +\- sqrt( 5^2 - 4(1)(-176)) )  /2

 =     ( -5 +\- sqrt( 25 +  704) )/ 2

=     ( -5 +\- sqrt (729) ) /2                            => as sqrt(729) = 27

=      (-5 +\- 27) / 2                                        =>

=      (-5 + 27)/2 or ( -5 -27)/2                      =>

=      22/2  or  -32/2                                     =>

=      11 or  -16


But -16 is not allowed as the question wants a positive value.



Thank you,

MrB
