A number c minus 6 is less than or equal to 5.3. Write this word sentence as an inequality.
forsale [732]

Answer:

C - 6 < = 5.3

Step-by-step explanation:

Writing the above as an equality, we would have ;

Since C is less than 6, then;

C - 6

Therefore, C minus 6 is less than or equal to 5.3 is

C - 6 < = 5.3

An inequality is when an unequal relationship exist between two expressions, which uses signs such as not equal to , less than < , greater than > etc.

Which equation should be used to find the volume of the figure?​
77julia77 [94]

Answer:

Option 1

Step-by-step explanation:

the formula for finding the volume of a pyramid is lwh/3. in this case the length or l is 6, the width or w is 4 and the height or h is 8, multiply all of those and then multiply the product of that by 1/3 or divide lwh by 3, either way youll get the same thing. the 10 inches is useless for finding the volume btw

Which graph represents this system of equations?<br> y + 2x = 3<br> y + 2 = 3x
andrezito [222]

Answer:

The options are not given, so i will answer in a general way.

First, we have the system:

y + 2*x = 3

y + 2 = 3*x

To graph this system, the easier way is writing both equations as linear equations, like:

y = -2*x + 3

y = 3*x - 2

Now we just need to graph these two lines in the same coordinate axis.

To do it, we can replace the value of x by two different values in each equation, and see the correspondent value of y for these values. Then graph the two points, and draw a line that connects them.

For example, for the first equation if we have x = 0, we have:

y = -2*0 + 3

y = 3

Then we have the point (0, 3)

and if x = 1

y = -2*1 + 3 = 1

y = 1

we have the point (1, 1)

Now we only need to graph these points, and draw a line that passes through them.

Once we did this for both lines, the graph we will get will look something like the one above.

And the point where the lines intersect is the solution of the system of equations.

Which is the point (1, 1)

The volume of the composite figure is 3532.5 cubic inches

<h3>How to determine the volume of the composite figure?</h3>

From the given figure, we have the following dimensions:

  • Height, h = 15 inches
  • Radius of small cylinder, r = 5 inches
  • Radius of large cylinder, R = 10 inches

The volume of a cylinder is

V = πr^2h

So, the volume of the composite figure is

V = πR^2h - πr^2h

Substitute the known values in the above equation

V = 3.14 * 10^2 * 15 - 3.14 * 5^2 * 15

Evaluate the product

V = 3532.5

Hence, the volume of the composite figure is 3532.5 cubic inches
