Answer:

0.6%

Step-by-step explanation:

\frac{24}{4000} = 0.6%

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 4000 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 4000, so we can write it down as 100%=4000.

4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.

5. Now we have two simple equations:

1) 100%=4000

2) x%=24

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=4000/24

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24 is what percent of 4000

100%/x%=4000/24

(100/x)*x=(4000/24)*x       - we multiply both sides of the equation by x

100=166.666666667*x       - we divide both sides of the equation by (166.666666667) to get x

100/166.666666667=x

0.6=x

x=0.6

now we have:

24 is 0.6% of 4000

Find the vertex of y=-x^2+6x-12
Debora [2.8K]
You find the x coordinates using x = -b/2a  = -6/2(-1) = 3

Substitute 3 in the equation and find y

y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3

Find the slope of the line passing through the points given below or state that the slope is undefined. Then indicate whether th
Alex17521 [72]

Answer:

The slope is 3 and the line is rising.

Step-by-step explanation:

To find the slope m of a line given two points (x₁, y₁) and (x₂,y₂) we can use the formula:

m = (y₂-y₁) / (x₂ - x₁)

In this problem we have the points (6,2) and (7,5), substituting these values in the formula we get:

m = (5 - 2) / (7 - 6) = 3/1 = 3

Therefore, the slope is 3.

Given that the slope is positive we can conclude that the line through the points rises.

which of the following are among the five basic postulates of euclidean geometry? check all that apply
MAVERICK [17]
The five essential hypothesizes of Geometry, additionally alluded to as Euclid's proposes are the accompanying: 
1.) A straight line section can be drawn joining any two focuses. 
2.) Any straight line portion can be expanded uncertainly in a straight line. 
3.) Given any straight line fragment, a circle can be drawn having the portion as a span and one endpoint as the inside. 
4.) All correct points are harmonious. 
5.) If two lines are drawn which meet a third such that the total of the internal points on one side is under two right edges (or 180 degrees), then the two lines unavoidably should converge each other on that side if reached out sufficiently far.
