I am pretty sure its false. I think this becuase 1/2 goes into 3, 6 times, not 1 time. Hope that helps

Which numbers qre the solutions of the inequality?<br><br>x &gt; - 5; -7, 5, -1
solmaris [256]

-1 and 5

x> -5

5 is more

-1 is more

-7 is less.

Higher the number is in negative numbers, the lower it is. Lower the number it is in negatives, the higher it is. so like -8 is higher than -10 and -4 is lower than 0.

The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13
Iteru [2.4K]

Answer:

283 cm^2

Step-by-step explanation:

Solution:-

We have a cone with a circular base of radius r = 5 cm

The height of the cone is h = 12 cm

The slant height of the cone is L = 13 cm

We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:

         Base Area : Circle

               A_1 = \pi r^2\\\\A_1 = \pi 5^2\\\\A_1 = 25\pi

        Curved Surface: conical

                A_2 = \pi * r*L\\\\A_2 = \pi * 5*13\\\\A_2 = 65\pi

The total surface area of the cone can be written as ( A ):

               A = A_1 + A_2\\\\A = (25 + 65 )*\pi \\\\A = 90*(3.14) \\\\A = 282.7433 cm^2

Answer: The surface area of the cone to nearest whole number would be 283 cm^2

Write the equation. Solve for x.
strojnjashka [21]

Answer:

X = 3

Step-by-step explanation:

First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.

5x + 2 = 17

Then Solve For X

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide by 5

X = 3

Check your answer

5(3) +2 = 17

15 + 2 = 17

17 = 17

It is correct!

Which graph represents the solution to the compound inequality?<br><br> –6 &lt; 3x – 12 ≤ 9
andrey2020 [161]

Answer:

second graph

Step-by-step explanation:

Solving the inequality

- 6 < 3x - 12 ≤ 9 ( add 12 to all 3 intervals )

6 < 3x ≤ 21 ( divide the intervals by 3 )

2 < x ≤ 7

The graph has an open circle at 2 and a closed circle at 7

This is represented on the second graph
