Open or closed circle? What is the answer for the number line? What is the solution?

Amanda [17]

To isolate m, we'll multiply both sides by 8.

We go from m/8 < 4 to m < 32

This describes any number smaller than 32. We aren't including 32 itself, so we have an open circle at 32 on the number line. The shading is to the left since everything to the left of 32 is smaller than 32.

Step-by-step explanation:

3. The length of the rectangle is 3x and width is x+5

Now,

Area of rectangle=l×b

=3x(x+5)

=3x^2+15x(option d.)

4. 2/3x-4=20

2x/3=20+4

2x/3=24

2x=24×3

2x=72

x=72/2

x=36(option d.)

If you're ladder is 10 feet long and you place the bottom 6 feet from the wall how far can you reach

-Dominant- [34]

This is like a triangle.
One side, the hypotenuse, is the length of the ladder, 10 feet in this case.
Another side, one of legs, is the distance from the bottom of the ladder to the side of the wall, 6 feet.
The last side is what we need to find, how high up the ladder reaches.

Using the pythagorean theorem, we can find this third side.
This is written as a^2 + b^2 = c^2.
A and B are the legs, while C is the hypotenuse.

Plugging in known values, we get:
6^2 + b^2 = 10^2

Solve as much as possible:
6^2 = 36
10^2 = 100
36 + b^2 = 100

Now you must isolate b.
Subtract 36 from both sides.
100 - 36 = 64
b^2 = 64

The last step in finding b is doing the inverse of squaring, which is square rooting.
√64 = 8
So b equals 8.

This means that the ladder can reach 8 feet up the wall.

Step-by-step explanation:

Alright, lets get started.

Diameter of baseball is given as 3 inches.

Hence the radius of baseball will be : $\frac{3}{2}=1.5$
