Answer:

Step-by-step explanation:

c + a = 342 ..................... <em>(1)</em>

5c + 12a = 2550 ........... <em>(2)</em>

- 5 × <em>(1)</em> + <em>(2)</em>

7a = 840

<em>a = 120</em>

<em>c</em> = 342 - 120 <em>= 222</em>

Answer:

x=30, A=132

Step-by-step explanation:

These 2 angels are alternate interior angles so they are equal

5x-18=3x+42

Solve.

2x=60

x=30

Now substitute x into angle A

A=150-18

A=132

lions [1.4K]

Answer:

48.06  to the nearest hundredth.

Step-by-step explanation:

f(x) = -16x^2 + 2x + 48

To find the maximum height we convert to vertex form:

= -16(x^2 + 1/8x) + 48

= -16[x + 1/16)^2 - 1/256] + 48

= -16(x + 1.16)^2  + 16/256 + 48

= 48.0625.

ratelena [41]

Volume is a three-dimensional scalar quantity. The volume of the space between the cylinder and the two cones is 1184.43183 cm³.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the circumference of the base is 61 cm, therefore, the radius of the base will be,

Circumference = 61 cm

2πR = 61

R = 61/(2π) = 9.70845 cm

The volume of the cylinder(Outside shell) can be written as,

Volume = πR²×H

             = π× (9.70845)² ×12

             = 3553.29326 cm³

The volume of the two identical cones will be,

The volume of the cone = 2× (1/3) × π × R² × H

                                        = (2/3)×π×(9.70845²)×12

                                        = 2368.86143 cm³

The volume of the space between the cylinder and the two cones is,

The volume between space = 3553.29326 cm³ -  2368.86143 cm³

                                                = 1184.43183 cm³

Hence, the volume of the space between the cylinder and the two cones is 1184.43183 cm³.
