Answer:

y = 24

Step-by-step explanation:

We can dilate the other sides to figure out what the scale factor is. Once we know the scale factor we can find y.

Divide 12 by 4.

12 / 4 = 3

The scale factor is 3.

Now we must multiply 8 by 3.

8 * 3 = 24.

y = 24.

Solve for x................

alexandr402 [8]

Answer:

Option C

$x={1(+/-)2\sqrt{3}}$

Step-by-step explanation:

we have

$x^{2}-2x-11=0$

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-2x-11=0$

$a=1\\b=-2\\c=-11$

substitute

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-11)}} {2(1)}$

$x=\frac{2(+/-)\sqrt{4+44}} {2}$

$x=\frac{2(+/-)\sqrt{48}} {2}$

$x=\frac{2(+/-)4\sqrt{3}} {2}$

$x={1(+/-)2\sqrt{3}}$

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 48 cm³.

Taya2010 [7]

Answer:

32 cm³

Step-by-step explanation:

Volume of a sphere is:

$V_{s}=\frac{4}{3}\pi r^{3}$

Volume of a cylinder is:

$V_{c} = \pi r^{2} h$

The volume of the cylinder is 48 cm³.

The cylinder has the same radius (r) and height (2r) as the sphere.

$48 = \pi r^{2} (2r)\\48 = 2\pi r^{3}\\24 = \pi r^{3}$

Therefore, the volume of the sphere is:

$V_{s}=\frac{4}{3} (24)\\V_{s}=32$

Ashley is keeping track of the growth of a bamboo plant. When she purchased the plant last month its height was 8.75 inches. Its

Margarita [4]

Answer:

Step-by-step explanation:

Amount by which the plant gre in one month = 9.5 - 8.75 = 0.75

Amount by which it will grow in x months = x * 0.75

The hegiht of the plant after 6 months = amount it will grow by in 6 months + current heigt = 0.75x + 8.75

Hence answer is
