If y varies directly with x, then whatever is done to y is also done to x, and vice versa.
All of the answers relate to when the value of y is positive 1, meaning we have divided the original y by -10.
We must also do this to x, as they are directly proportionate, meaning x = 2 now becomes x = -1/5
Therefore the answer is [B]
It’s 678m2 because Given the dimension of a rectangular prism l×b×h,its surface area is 2(lb+bh+lh)Hence surface area of a rectangular prism that measures 12 m x 11 m x9 mis 2×(12×11+11×9+12×9)= 2×(132+99+108)= 2×339=678m2
The greatest number is 8 because when you measure the number between 8&3 its more than likely 8
The height of the cylinder is 6 cm.
If the volume of the cylinder is 54π cm³, and we know the radius, we can use the formula for the volume of a cylinder to figure out the length of the height.
V = πr²h
Substitute
54π = 9h<span>π
</span>
Divide each side by <span>π
54 = 9h
Get h by itself
h = 6, which means that the height of the cylinder is 6 cm. </span>
