Answer:
The cube root would be 9. Cubed is just like squared, but a number multiplied 3 times to get the number 729.
Step-by-step explanation:
A way to solve it is:
729 / 3 = 243
243 / 3 = 81
81 / 3 = 27
27 / 3 = 9
9^3 = 729
9 • 9 = 81
81 • 9 = 729
Answer:
a 5-point star has rotational symmetry. A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.
So symetry will have a total of 360 degrees, then if you divide it by 5 ( the number of point in the star) you will get 72 degrees each so it has 5 reflections
Answer:
20%
Step-by-step explanation:
50+30=80
100-80=20
so you would pay 20%
11 because it asks for people older than 45 so it’s not 12. You just need to count how many number are after 45.
Answer:
The slope is -3
Step-by-step explanation:
the equation for finding the slope between two different points is:
M= (y2-y1)/(x2-x1)
Or in other words the change in y over the change in x.
M= (9+6)/(3-8) = 15/-5 = -3.
(sidenote: I added 9 and 6 for the change in y because you cannot subtract a negative number. Instead you have to add it.)
