394+12.5+49.5+39+19.95=514.95,
25.7475+514.95=540.6975
12 lessons*20=240
Grand total is 780.6975
If you mean: (√(16r)^6 that is the same as:
(16r)^(1/2)^6
relevant rule: (a^b)^c=a^(b*c), in this case
(16r)^(6*1/2)
(16r)^3
4096r^3
Answer:
1/5
Step-by-step explanation:
2 squares to 10 traingles is 2/10
But if you divide both top and bottom by 2, it simplifies to 1/5
Answer: 3<em>n</em> ants
Step-by-step explanation:
If there are n ants one month, and the ants triple every month, then next month there will be 3<em>n</em> ants.
We can multiply 3 by <em>n</em> to show it tripling.
To test this, 3(10,000) = 30,000 and 3(270,000) = 810,000, which corresponds to what you've filled out in the table.
Answer:
B'(16,14)
Step-by-step explanation:
In square ABCD, A(2,7) C(8,1) D(2,1). First, find the coordinates of the vertex B. From the attached diagram you can see that CD=6 units and is parallel to the x-axis, AD=6 units and is parallel to the y-axis. So, B(8,7).
The origin O is the center of dilation, 2 is the scale factor. The rule of the dilation is
(x,y)→(2x,2y)
Thus,
B(8,7)→B'(16,14) (see attached figure).
