Answer:
1/6
Step-by-step explanation:
Total outcome of rolling two fair dice: 6 x 6 =36
possible outcome of landing on same number: (1,1)(2,2)(3,3)(4,4)(5,5)(6,6)
= 6
probability: 6/36 = 1/6
The answer to this is -9 < x < -19
Answer:
27mi
Step-by-step explanation:
Since the sailing course is equilateral in shape, then all their sides are equal.
Get one of the sides using Pythagoras theorem as shown;
Let one of the side be x
Two base will be x/2
According to the theorem;
x² = 9² +(x/2)²
x² = 81 + x²/4
x²-x²/4 = 81
3x²/4 = 81
3x² = 324
x² = 324/4
x² = 81
x = 9
Perimeter of the triangle = 3x
Perimeter of the triangle = 3(9)
Perimeter of the triangle = 27mi
Answer: (2,-2) (-1,1) (-3,-1) (-2,-4)
Step-by-step explanation:
The x-axis is the horizontal line and the y-axis is the vertical line on a graph. The ordered pairs are always in (x,y).
To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).
Answer and step-by-step explanation:
20. Because the discount is 20% of the given price so the discount would be"
228/100*20
= 45.6 Rs
Its selling price would be:
228 + 45.6 = 273.6 Rs
21. Sales tax would be:
450/100*5
= 22.5 Rs
Total price in bill = 22.5 + 450 = 472.5 Rs
22. 10% tax of 3300 would be:
3300/100*10 = 330 Rs
Price before tax = 3300 - 330 = 2970 Rs
23. He spent in total of:
2500 + 500 = 3000Rs
He sold for 3300 Rs
He gain 3300 - 3000 = 300 Rs profit
His loss gain percent = 3300/3000 * 100 = 110%
24. On the first bike, he earn:
2500/100*20 = 500 Rs
On the second bike, he lose:
2500/100*25 = 625 Rs
He lose in total of 625 -500 = 125 Rs
his loss percentage = (2500+500) + (2500 - 625) / 5000* 100
= 100% - (2500+500) + (2500 - 625) / 5000* 100
= 100% - 97.5%
He lose 2.5% money
Hope this helped :3
