Please answer all 3 questions

blsea [12.9K]

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>

m∠AEB = 3x

m∠AEB = 90°

3x = 90° ⇒ x = 30°

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

<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.
