A rational number is any number that can be made into a fraction and is either repeating or stops when in decimal form.

Rational numbers between 3 and 3.5 would be 10/3 (3.33 repeating), and 13/4 (3.25).

Hope this helps!! :)

What's the slope?? Thank you!!! :)))

Alja [10]

Answer:

The slope of this line is 4

Step-by-step explanation:

The slope is determined with two points.

Take the pairs (0, - 9) and (1, - 5).

The slope is:

m = (y₂ - y₁) / (x₂ - x₁) = (- 5 - (-9)) / ( 1 - 0) = 4/1 = 4

A line segment as an endpoint (0,-1) and a midpoint: (1,-8). The other endpoint is

Digiron [165]

Answer: ( 2 , - 15 )

Step-by-step explanation:

Given :

endpoint = ( 0 , -1 )

midpoint = ( 1 , - 8 )

Let the other end point be ( x , y )

The equation for finding the mid point of a line segment is given by :

mid point = ( $\frac{x_{1}+x_{2}}{2}$ , $\frac{y_{1}+y_{2}}{2}$

This means

(1 , -8 ) = ( $\frac{0 + x}{2}$ , $\frac{-1 + y }{2}$ )

Equating the x - component , we have

1 = $\frac{0 + x}{2}$

1 = x/2

Therefore

x = 2

Also equating the y - component

- 8 = $\frac{-1 + y }{2}$

-16 = -1 + y

-15 = y

Therefore :

y = -15

Therefore , the other endpoint is :

( 2 , - 15 )

In Mr.Johanessen's class, 1/4 of the students failed the exam. Of the remaining class, 1/3 scored an A. What fraction of the who

lord [1]

so a whole is same/same, in this context is 4/4 = 1, or four fourths.

now, we know 1/4 failed, that means 4/4 - 1/4 = 3/4 didn't fail, so 3/4 passed.

from that remaining 3/4, how many got an A? well 1/3, how much is 1/3 of 3/4? well is just their product, $\bf \cfrac{1}{3}\cdot \cfrac{3}{4}\implies \cfrac{1}{4}$ .

so 1/4 of the remaining 3/4 got an A, that means 3/4 of the remaining 3/4 did NOT get an A.

how much is 3/4 of 3/4? well, is just their product.

$\bf \cfrac{3}{4}\cdot \cfrac{3}{4}\implies \cfrac{9}{16}\impliedby \textit{passed with score less than A}$

The formula v =sqrt 64h can be used to find the velocity, v, in feet per second, of an object that has fallen h feet. Find the v

miskamm [114]

To solve the problem shown in the figure attached in the exercise, you must follow the proccedure shown below:

1. You have that the formula for calculate the velocity (v) in feet per second (ft/s), of an object that has fallen h feet is:

v=√(64h)

2. The problem shown above asks for the velocity of an object that has fallen 23 feet. Therefore, to solve this exercise you only have to susbtitute h=23 feet into the formula for calculate the velocity (v), as below:

v=√(64h)

h=23 feet

v=√(64)(23)
v=√(1472)
v=8√23
v=38.37 feet per second

3. Therefore, as you can see, the correct answer is the second option, which is: 38.37 feet per second
