Answer:

6 cm,12 cm,8 cm

Step-by-step explanation:

add the perimeter of the first triangle to get 65

then divide 65 by 26 to get 2.5

then divide all the side lengths by 2.5

15/2.5=6

20/2.5=8

30/2.5=12

Given : y = -25 and x = -5

We can notice that if we Multiply 'x' with 5 we get 'y'

That is (-5) × 5 = -25

⇒ x multiplied by 5 = y

(a) The Equation that relates x and y is 5x = y

(b) We found that the Equation of this Direct variation is : 5x = y

The Question is to find the value of y when x = 3

The Value of y at x = 3 can be found by simply substituting x = 3 in the equation we found.

⇒ y = 5x

⇒ y = 5 × 3

⇒ y = 15

So, the Value of y when x = 3 is 15

Which equation represents a line which is perpendicular to the line y = 4/3x-6
SCORPION-xisa [38]
In order to be perpendicular, you must have a slope that is the opposite reciprocal, so the slope should by -3/4. So the equation could be y = -3/4x with any other number at the end.

Olenka [21]

Answer:

96\pi \: or \: 301.59

rounded to the nearest hundredth

Step-by-step explanation:

use the pythagorean theorem to find the height of the cone

{a}^{2}  +  {6}^{2}  =  {10}^{2}

you get a = 8

the formula for the volume of a cone is

\pi \:{r}^{2}  \frac{h}{3}

plug in 6 for the radius and 8 for the height. then solve
