Given:
The side of the square = [tex]9\sqrt{6}[/tex] m
To find:
The diagonal of the square.
Solution:
We know that the diagonal of a square is:
[tex]d=a\sqrt{2}[/tex]
Where, d is the length of diagonal and a is the side of the square.
Putting [tex]a=9\sqrt{6}[/tex], we get
[tex]d=9\sqrt{6}\sqrt{2}[/tex]
[tex]d=9\sqrt{12}[/tex]
[tex]d=9(2\sqrt{3})[/tex]
[tex]d=18\sqrt{3}[/tex]
Therefore, the diagonal of the square is [tex]18\sqrt{3}[/tex] m.

Eva payrolls for on a number cube and the number of cubes roll 24 times then what is a reasonable prediction for the number of successful Rolls
Answers
Answer:
The reasonable prediction for successful rolls is 4.
Step-by-step explanation:
Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as
[tex]P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}[/tex]
[tex]P(Success)=\dfrac{1}{6}[/tex]
The total success is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events[/tex]
For 24 rolls it is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4[/tex]
So the reasonable prediction for successful rolls is 4.

A bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow. A marble is drawn at random. What is the probability that it is not yellow.
Answers
Answer:
There is a 9/10 probability that the marble will not be yellow.
Step-by-step explanation:
If there are a total of ten marbles, and there is one yellow marble, there is a
1 yellow marble / 10 total marbles chance of getting a yellow marble. Then subtract it from 10/10 to get the probability of NOT getting a yellow marble.
10/10 - 1/10 = 9/10.
Answer:
9/10

[tex]given \: that \: p = {x}^{2} + 4x - 2 \: and \: q = 2x - 1 \: and \: q - p = 2 \: find \: x[/tex]
Answers
Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 (Expand bracket)
-x² -2x +1=2 (Simplify)
x² +2x +2 -1= 0 (Bring all terms to one side)
x² +2x +1= 0
(x +1)²= 0 (Factorise)
x +1= 0 (Square root both sides)
x= -1 (-1 on both sides)
Mark rides his bike from his house to the closest edge of the park, across the length of the park, and then back home. The distance from his house to the closest edge of the park is 0.9 km and the distance from the far side of the park to his house is 1.6 km. The map shows the path Mark took on his bike. If ∠B = 85° on the map, then use the law of cosines to determine the length of the park in kilometers.
Answers
Answer:
The length of the park is approximately 1.77 kilometers
Step-by-step explanation:
The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known
The given parameters of the question are;
The distance from Mark's house to the edge of the park, a = 0.9 km
The distance from the far side of the park to Mark's house, c = 1.6 km
Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;
b² = a² + c² - 2·a·c·cos(B)
Where;
b = The length of the park in kilometers
By plugging in the known values of 'a', 'b', and 'c', we get;
b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089
∴ b = √(3.11899146089) ≈ 1.76606666377
Therefore, the length of the park, b ≈ 1.77 km.

Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
