Answer:
Blue: 13/100 = 0.13 = 13%
Purple: 130/100=1.3=130%
Step-by-step explanation:
The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.
X=12
(10(12)-20) = 120-20 = 100
(6(12)+8) = 72+8=80
100+80 = 180
Answer:
8.60
Step-by-step explanation:
A^2+B^2=C^2
5*5=25 7*7=49 49+25= 74
√ 74= 8.602...
Answer:im not really sure but i think log3(3) Logarithm base 3 of 3 is 1 .
Step-by-step explanation:
Answer:
(3) y = 4x
Step-by-step explanation:
In order for the equation not to change, the point (0, 0) must be on the original line and so on the line after dilation. The only equation with (0, 0) as a point on the line is y=4x.
Dilation about the origin moves all points away from the origin some multiple of their distance from the origin. If a point is on the origin, it doesn't move. We call that point the "invariant" point of the transformation. For the equation of the line not to change, the invariant point must be on the line to start with.
