Answer:

0.25 pounds

Step-by-step explanation:

You set up an equation with the given information:

  1. 4x+2(2.5)+2(3)=2x+1(2.5)+3(3)
  2. Multiply: 4x+5+6=2x+2.5+9
  3. Add: 4x+11=2x+11.5
  4. Subtract: 4x=2x+0.5
  5. Subract: 2x=0.5
  6. Divide: x=0.25

Now check your work:

  1. 4(0.25)+2(2.5)+2(3)=2(0.25)+1(2.5)+3(3)
  2. Multiply: 1+5+6=0.5+2.5+9
  3. Add: 12=12

If a cone is 5 meters tall and has a radius of 3 meters, What is its volume? 15π m3 60π m3 45π m3 30π m3
nydimaria [60]

Answer:

V = 15 pi m^3

Step-by-step explanation:

The volume of a cone is

V = 1/3 pi r^2 h

The radius is 3 and the height is 5

V = 1/3 pi ( 3)^2 *5

V = 15 pi m^3

Solve this system of linear equations. Separate
alex41 [277]

Answer:

y = 7 and x =3

Step-by-step explanation:

use elimination method

so we gonna eliminate y first

9x = 1 - 4y

-7x = -7 + 4y

7| 9x = 1 - 4y

9| -7x = -7 + 4y

63x = 7 - 28y

-63x = -63 + 36y

add eqtn 1 to eqtn2

you will get

0 = -56 + 8y

56 = -56 + 56 + 8y

56 = 8y

56÷8 = 8y÷ 8

7 = y

also eliminate x as we have done wth y

4| 9x = 1 - 4y

4| -7x = -7 + 4y

36x = 4 - 16y

-28x = -28 + 16y

add the two equations

u will get

8x = -24 + 0

8x = -24

8x÷8 = 24÷ 8

x = 3

To fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and ___
Vikki [24]

Answer:

C. asymptotes

Step-by-step explanation:

In the figure attached, a sign chart is shown. To fill it out you need to find the function's zeros and asymptotes. The zeros are those x values that makes the function equal to zero, in the example, those are the x values that make the denominator equal to zero (x = -1 and x = 5). In a rational function, the asymptotes are those x values that make the numerator equal to zero (x = -9 in the example)

Function in the example:

\frac{(-2x-2)(2x-10)}{-9x-81}
