Answer:

13.7

Step-by-step explanation:

The computation of the volume of toy A is shown below:

7 × k^2=9

k^2= 9 ÷ 7

k=√9 ÷ 7

k = 1.133893419

Now

= 20 ÷ 1.133893419³

=13.7

for the equation x over 3 equals 15 the student found the value of x to be 5 explain the error what is the correct answer
otez555 [7]
If you divide 5 over 3 you get the decimal 1.6, not 15.
the correct answer would be 45. 
how do i get that? read below.
________________________________

\frac{x}{3} = 15
1.multiply each side by 3, to get the 3 on the left side to cancel out. so you get x = 15 times 3.

A figure has a vertex at (-1, -3). If the figure has line symmetry about the y-axis, what are the coordinates of another vertex
Cloud [144]
Its (1,-3) simply reflect it above the y-axis, if one vertex is on the negative side and the symmetry if about the y axis (y=0) therefore the reflection means the x value becomes inverse -1 changes to 1 and -3 remains the same
