Answer:

<h2>No Solution</h2>

Step-by-step explanation:

- 3(x + 3) =  - 3(x + 1) - 5

Expand

- 3(x + 3) =  - 3x - 9 \\  - 3(x + 1) =  - 3x - 3

- 3x - 9 =  - 3x - 3 - 5

Collect like terms and simplify

- 3x + 3x =  - 3 - 5 + 9 \\ 0x = 1

Find the volume of a right circular cone that has a height of 15.6 cm and a base with a radius of 7.8 cm. Round your answer to t
sergey [27]

Answer:

356.8cm3

Step-by-step explanation:

Volume of a cone= 1/3 * base area * height.

Note: don't be confused by right circular cone ; a cone is gotten from a cylinder by dividing it into three parts. One from the right vertex slanted to the middle of the base; another from the left vertex slanted to the middle of the base and the remaining portion with the surface base at the top.

Going forward; base area =pi * raduis * raduis [ area of a circle; the base is a circle]

Volume= 1/3 * (3.142 * 7.8 * 7.8 *5.6) = 356.83cm3

Volume= 356.8cm3 [ to the nearest tenth].

Tenth means 1/10= 0.1; that is value after the decimal point.

Help!! Please I’m stuck give [10pts]
pishuonlain [190]

Answer:

x = 18

Step-by-step explanation:

To solve this problem, we can use the exterior angle theorem, which means the measure of an exterior angle is the sum of its remote interior angles. In this case, this would mean:

x + 72 = 5x

Since this gives us an equation, we can just solve for x:

x + 72 = 5x

72 = 4x

x = 18
