Answer: not a right triangle

Step-by-step explanation:

A bag contains 9 marbles: 3 are green, 2 are red, and 4 are blue. Bob chooses a marble at random, and without putting it back, c
kvasek [131]

Answer: 1/18

Step-by-step explanation:

9 total marbles

2 red

so the first time he picks it would be a 2/9 chance of the marble being red

the second time there would be 8 total marbles and 2 red, so it would be a 2/8 or 1/4 chance.

the probability is found by doing 2/9*1/4 which equals 2/36 or 1/18.

A taxicab charges $3.00 per person
Delicious77 [7]

Answer:

I believe the answer would be 20 miles max for one passenger.

Step-by-step explanation:

This is because if you create an equation out of this, knowing that only one passenger will be riding, you will get:

$3.00+$1.25x=$28       ($3 added too $1.25 times the number of miles (x) which equals the total amount you have ($28)).

x being the number of miles (so we need to calculate for x)

$3 + $1.25x = $28

-subtract 3 on both sides-

$1.25x=$28-$3

$1.25x=$25

-divide by 1.25 on both sides-

x=$25/$1.25

x=20 miles

Not sure if all calculations are correct, but I hope this helps :)!

How do I find the slope of the line through (–9, –10) and (–2, –5)?
storchak [24]
Answer:
slope of line is 5/7

Explanation:
The slope of the line can be calculated using the following rule:
slope = \frac{y2-y1}{x2-x1}

The given points are:
(-9,-10) which represent (x1,y1)
(-2,-5) which represent (x2,y2)

Substitute with the points in the above equation to get the slope as follows:
slope = \frac{-5-(-10)}{-2-(-9)} = 5/7

Hope this helps :)
