840
10% =84 (840/10)
5% =42 (84/2 or 840/20)
therefore 840+42=882

If there are 840, then you can multiply it by 1.05 to get the answer. This is the same as finding 5% of 840 and then adding that to 840, but this does it in one computation. 840 * 1.05 = 882
The current population would be 882.

1. What is the solution of n² – 49 = 0? (1 point)
maks197457 [2]

Answer:

1. n=\pm7

2. x=\pm7i[tex]3.[tex]\pm 12x =a

4. 22

Step-by-step explanation:

1. n^2 - 49 = 0

n^2 =49

n= \sqrt{49}

n=\pm7

2. x^2+64 = 0

x^2 =-64

x= \sqrt{49}

x=\pm7i[tex]3. Area of square = [tex]a^{2}

Where a is the side

We are given an area o square = 144x^{2}

So, 144x^{2}=a^{2}

\sqrt{144x^{2}}=a

\pm 12x =a

4. We are given that the solution of quadratic equation -9 and 9

So, equation becomes:

(x+9)(x-9)=0

x^2- 81=0

So, in the given equation x^2 + z = 103

z should be the number from which if we subtract 103 so we get 81

Substitute z = 22

x^2 + 22 = 103

x^2 + 22 -103=0

x^2 -81=0

Thus the value of z is 22

What is the height of an isosceles trapezoid, if the lengths of its bases are 5m and 11m, and the length of a leg 4m
son4ous [18]

In the isosceles trapezoid ABCD, draw two perpendiculars AM and BL from A and B to the side CD.  

Now, LM = BA = 5 m  

CD = CL + LM + MD

       = CL + 5 + CL (CL = MD)

      = 2CL + 5  

But, CD = 11

Therefore, 2CL + 5 = 11

2CL = 11 - 5

       = 6

CL = 6/2 = 3m

MD = 3m

Now, consider the right triangle AMD.

We have,  

AM^{2} = AD^{2} - MD^{2}

                  = 4^{2} - 3^{2}

                  = 16 - 9

                 = 7

Hence, height of the isosceles trapezoid = AM = \sqrt{7} m
