Bao owns a small business selling used books. She knows that in the last week 20

Bumek [7]

Answer:

44% cahnce

Step-by-step explanation:

To solve this, add up all the customers. Then, divide the amount of debit card customers, by the total amount of customers. This will give you percentage of people who paid in debit, which is also the probability:

20+26+13

=

59

This is the amount of customers. Now we divide:

26/59

=

0.4406

Remember that to create percentage, you must multiply the decimal by 100:

0.4406*100

=

44.06%

The .06 is so small that it doesnt need to be kept in this percentage:

44%

So this is you answer!

Hope it helps! :)

Find X such that f(x)=0 for f(x)= -2x^2-x

Leokris [45]

Answer:

$x=\{-\frac{1}{2} ,\:0\}$

Step-by-step explanation:

$f(x) =-2x^2 -x\\plug \: f(x) =0\\0= -2x^2 -x\\2x^2 + x = 0\\x(2x+1) = 0\\\therefore x =0 \: or \: 2x+1 = 0\\\therefore x =0 \: or \: 2x = -1\\\\\therefore x =0 \: or \: x = -\frac{1}{2} \\\\x=\{-\frac{1}{2} ,\:0\}$

Please help! Fast! It needs to be done and show me the steps.

mr_godi [17]

---------------------------------------------
Formula
---------------------------------------------
Sum of all exterior numbers = 360°

---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360

---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360

---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108

---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54

---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°

---------------------------------------------
Answer: 99°

A rectangular swimming pool is 20 ft long 15 feet wide,and 6 feet deep. How much water is needed to fill the pool completely ?

sergejj [24]

Answer: 1,800 ft.³

Step-by-step explanation: To find out how much water is needed to fill the pool, we need to find the volume of the pool. It's also important to understand that the swimming pool is a rectangular prism so we are finding the volume of a rectangular prism.

To find the volume of the pool, we use the formula shown.

<em>Volume = length × width × height </em>

Since the length of the pool is 20 feet, the width is 15 feet, and the depth or height is 6 feet we can plug this information into the formula.

Volume = (20 feet) (15 feet) (6 feet) = 1,800 ft.³

Therefore, it will take 1,800 cubic feet of water to fill the pool.
