y ≤ 1/3x - 4

Step-by-step explanation:

it could not be options 3 or 4 because the y-intercept is -4, not +4

I picked a point in the shaded area to see which inequality, the first or the second, would make it true; the point I used was (3, -4)

1st option:  y ≥ 1/3x - 4        Is this true? -4 ≥ 1/3(3)  No, -4 is not GE 1

Given this number line, DB = [?]

Answers

The required measure of the number line DB = 6.

GIven that,
A figure of number line shown, and a number has been marked on the number line A = 4, B = 7, C = 11, and D = 13
The measure of DB is to be determined.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

What is simplification?

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

since
On the given number line, marked from 4 to 13 or from A to D,
Total length AD = 9, which implies the line is distributed in 9 equal parts from 4 to 13.

Now measure of DB = AB - AD
                               = 13  -  7
                               = 6
Implies that there are equal parts of the line in DB.

Thus, The required measure of the number line DB = 6.

Raul is practicing for baseball tryouts he wants to find how far he can hit a baseball he hits the ball 10 times and measures the distance the ball travels each time which measure should roll used to learn the average distance he hit the ball

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]n = 10[/tex] --- Number of tryouts

Required

Determine the average distance

This question has missing details, as the distance he hits the ball in each tryout is not given. However, I'll give a general explanation.

The mean is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\sum x[/tex] means the sum of the distance in each tryout.

Assume that the distance in the 10 tryouts are: [tex]6, 8, 5, 9, 4, 5, 8, 7, 7, 6.[/tex]

So, the mean is:

[tex]\bar x = \frac{6+ 8+ 5+ 9+ 4+ 5+ 8+ 7+ 7+ 6}{10}[/tex]

[tex]\bar x = \frac{65}{10}[/tex]

[tex]\bar x = 6.5}[/tex]

So, the average distance is 6.5

-7 > -10

Step-by-step explanation:

We just have to compare these two numbers. When you're comparing two negative numbers, the smaller number is the bigger one. Ex. -3 is bigger than -6, so we can say that -3 > -6 (-3 is greater than -6). This means that -7 is larger than -10, which allows you to say that -7 > -10.

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 250 feet, what is the height of the building?

250 ft

50 ft

Answers

Answer:  244.95 feet

Step-by-step explanation:

This scenario forms the shape of a right angled triangle with the shadow length being the triangle's length and the distance between the end of the shadow to the top of the building being the hypotenuse.

Use Pythagorean theorem:

c² = a² + b²

250² = 50² + b²

62,500 = 2,500 + b²

b²= 62,500 - 2,500

b² = 60,000

b = √60,000

b= 244.95 feet
