Mathematics

Answer:

$16

Step-by-step explanation:

1. Simplify 12/45 which is now 4/15. Now we know $4 is made every 15 minutes.

2. Divide into 60(minutes) by the the 15. So 60÷15=4. Now we the number of times 15 can be divided into 60.

3. Multiply the ratio 4/15 by 4/4 to see how much is made in an hour. 4x4/15×4=16/60.

$16 is made in 60 minutes (1 hour).

Answer:

p>-3 open circle going to the right

m\leq -4 closed circle going to the left

n<5 open circle going to the left

h\geq 2 closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is \leq  or\geq then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

m\leq -4 closed circle going to the left

n<5 open circle going to the left

h\geq 2 closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Select the THREE equations that this diagram could represent.
Vladimir [108]

<u>Question </u>

Select the three equations that this diagram could represent.

<u>                                                                                                                                     </u>

<u>Answer</u>

<em>Well, we first have to find out what the diagram says.</em>

<em>So what the diagram says is that  18 + 18 + 18 = 54.</em>

<em>Given this information,  we have to figure what other answers = 54.</em>

<em>Therefore the answers are </em>

(A) 18 * 3 = 54.

(D) 54/18 = 3

(E) 54/3 =18

In the xy- plane, the graph of the equation y + 3x + 5 is a line that intersects the y-axis at (0,b) what is the value of b?
maxonik [38]

Answer:

b=5

Step-by-step explanation:

The given equation is:

y=3x+5

To find the point where this line intersect the y-axis, we put x=0 into the given equation.

When x=0, we have y=3(0)+5.

This implies that; y=5.

The y-intercept is (0,5).

Comparing (0,5) to (0,b), we can conclude that; b=5

Help me with this please
Klio2033 [76]

Answer:

No, she's wrong

x\leq\frac{2}{5}

Step-by-step explanation:

So starting from the beginning...

3x+3\leq -2x+5

Subtract the 3 from both side and it will look like...

3x\leq-2x+2

Then add 2x from both sides and it will look like...

5x\leq 2

Finally divide by 5 to both sides and it will look like...

x\leq \frac{2}{5}
