Answer:
25
Step-by-step explanation:
if you look at it, 250 is 1/4 of 1000 and 100 is 1/10 of 1000 so divide 250 by 10 and you get your answer.
There are 16 smaller triangles within the main large one. .25=1/4, so your fraction is 1/4. 1/4 of 16 is 4, because 4+4+4+4=16. So colour in 4 triangles. Hope this helps!
Answer:
9
Step-by-step explanation:
n=3, a=729
For any odd integer, n ; a will have only one real nth root which will be a positive integer.
Similarly, for any integer, n, that is > 1 ; related by the expression ;
p^n = a ; the nth root of a = p
Therefore,
If n = 3 ; a = 729
p^3 = 729
To obtain the value of p ; take the cube of both sides
(p^3)*1/3 = 729^1/3
p = 9
Hence, the real nth root of 729 is +9 when n = 3
1. 1 x-200= -200
2. -200 x 1= -200
3. 2 x -100= -200
4. -100 x 2= -200
5. -20 x 10= -200
6. -10 x 20= -200
7. -40 x 5= -200
8. -5 x 40= -200
Hope this helps! :)
<span> The </span>Slope<span> (also called Gradient) of a straight line shows how steep a straight line is. To calculate the slope, you need two points from the graph. Then, get the difference of the y and x values of the points and divide y by x. We do as follows:
slope = y2-y1 / x2 - x1 = 1.4 - 7.2 / 18.1 + 5 = -0.2511</span>
