I DONT NEED SLEEP I NEED ANSWERS
stellarik [79]

Answer:

You asked to solve questions 3 and 5

<h3>#3</h3>

Since CD = EF,

  • 9x - 1 = 41 - 5x
  • 9x + 5x = 41 + 2
  • 14x = 42
  • x = 3
  • EF = 41 - 5*3
  • EF = 26
<h3>#5</h3>

MN = NP as their perpendicular bisectors are of same length.

  • 9x - 43 = 5x + 33
  • 9x - 5x = 33 + 43
  • 4x = 76
  • x = 19
  • mMP = 360 - (mMN + mNP)
  • mMP = 360 - (9*19 - 43 + 5*19 + 33)
  • mMP = 104

The sum of scores of ella and Kath in the summative test is not greater than 50. supposed Ella's score is 22 points, what could
Firlakuza [10]

We want to see which could be the possible score of Kath for the given information. We will find the inequality:

K ≤ 33

<h3>Stating what we know:</h3>

The given information is:

  • The sum of the scores is not greater than 55 points
  • Ella's score is 22 points.

<h3>Writing the inequality:</h3>

First, we need to define the variable K for Kath's points, because of the given information, we can write the inequality:

K + 22 ≤ 55

This means that the sum of the points is smaller than or equal to 55.

Now we just need to solve this for K, to do this, we subtract 22 in both sides:

K ≤ 55 - 22

K ≤ 33

From this, we can conclude that Kath has at most 33 points.

A piece of wire 23 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral tria
AURORKA [14]

Answer:

For maximum area, all of the wire should be used to construct the square.

The minimum total area is obtained when length of the wire is 10m

Step-by-step explanation:

For maximum,  we use the whole length

For minimum,

supposed the x length was used for the square,

the length of the side of the square = x/4m

Area = \frac{x^{2} }{16}

For the equilateral triangle, the length of the side =  \frac{23 - x}{3}

Area = \frac{\sqrt{3} }{4}  a^{2}  = \frac{\sqrt{3} }{4} (\frac{23 - x}{3} )^{2}

Total Area = \frac{x^{2} }{16}  + \frac{\sqrt{3} }{36} (23-x)^{2}

\frac{dA}{dx}  = \frac{x}{8}  -  \frac{\sqrt{3} }{18} (23 - x)\\

\frac{d^{2}A }{dx^{2} }  = \frac{1}{8}  + \frac{\sqrt{3} }{18}  > 0, therefore it is minimum

\frac{dA}{dx}  = 0 \\\\

\frac{x}{8}  -  \frac{\sqrt{3} }{18} (23 - x) = 0\\

x = 10.00m
