What is the scale factor used to create this dilation?

Mathematics

1 answer:

alex41 [277]4 years ago

4 0

The answer is: -1/5 or -0.2

One side of the original triangle is 15 units long and the side of the equivalent side of the dilated triangle is 3 units long. Therefore the magnitude of the enlargement scale factor is 3/15 or 1/5;

The answer is -1/5 as the transformation resulted in an inversion as well as an enlargement/dilation, therefore the answer is negative.

60 = 3h/4 this is for brainlessly

harina [27]

Answer:

80=h

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

4x60=4x3h/4

Then you get :

240=3h

Divide both sides of the equation by the same term

240/3 and 3/3 that means the 3 cancels out

Simply the fraction and your answer is 80

The volume of a sphere is 28/3 times it surface area, find the surface area

pentagon [3]

Answer:

615.44 units squared

Step-by-step explanation:

Let the volume and surface area of the sphere be V and S respectively.

$\therefore V = \frac{28}{3} \times S\\\\\therefore \frac{4}{3} \pi {r}^{3} = \frac{28}{3} \pi {r}^{2} \\ \\ \frac{ {r}^{3} }{ {r}^{2} } = \frac{28\pi}{3} \times \frac{3}{4\pi} \\ \\ r = 7 \: units \\ \\ \because S = 4\pi {r}^{2} \\ \\ \therefore \: S = 4 \times 3.14 \times {7}^{2} \\ \\ \therefore \: S = 12.56 \times 49 \\ \\ \therefore \: S =615.44 \: {units}^{2}$
