Answer:

  • x = 30°
  • DB = 26
  • AD = BC = AB = DC = 7

Step-by-step explanation:

  • <em>Diagonals of a square are congruent and perpendicular and bisect each other</em>
<h3>Q4</h3>

m∠AEB = 3x

m∠AEB = 90°

  • 3x = 90° ⇒ x = 30°
<h3>Q5</h3>

AE = 3x - 2

EC = 2x + 3

  • AE = EC
  • 3x - 2 = 2x + 3
  • 3x - 2x = 3 + 2
  • x = 5

DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26

<h3>Q6</h3>

<u>AD and BC are the sides, which are equal</u>

  • 2x - 1 = 5x - 13
  • 5x - 2x = 13 - 1
  • 3x = 12
  • x = 4

AD = BC = AB = DC =  2*4 - 1 = 7

Snowcat [4.5K]

Answer:

Speed = \frac{38}{3}km/hr

Step-by-step explanation:

Given

Distance = 3\frac{1}{6}km

Time = \frac{1}{4}hr

Required

Determine the average speed

Average speed is calculated as thus;

Speed = \frac{Distance}{Time}

Speed = 3\frac{1}{6}/\frac{1}{4}

Speed = 3\frac{1}{6} * \frac{4}{1}

Convert Mixed Fraction to Improper fraction

Speed = \frac{19}{6} * \frac{4}{1}

Speed = \frac{19 * 4}{6 * 1}

Speed = \frac{76}{6}

Divide both sides of the fraction by 2

Speed = \frac{38}{3}

Hence:

The speed is:

Speed = \frac{38}{3}km/hr

For the spinner above, the probability of landing on black is 1/2, and the probability of landing on red is 1/3. Suppose it is s
saul85 [17]

Answer:

d) The probability spinner will land on black all three times is 1/8

Step-by-step explanation:

The probability of landing on black = 1/2

The probability of landing on red    =  1/3.

Now, if the spinner is spun 3 times.

The probability  it will land on black all three times  

= \textrm{ (The probability of landing on black)}^3

= \frac{1}{2}   \times  \frac{1}{2}  \times  \frac{1}{2}  = \frac{1}{2 \times 2 \times 2 } = \frac{1}{8}

Hence, the probability spinner will land on black all three times is 1/8.
