Dixie drinks 1/3 a cup of water in 1/6 of a minute. How many cups of water per minute does Dixie drink?

Answers

2 drinks! Can I pls have brainliest??

Hello, 928747! I can help.

So, we're trying to find out how many cups of water Dixie can drink per minute.

Since there are 60 seconds in a minute, we can assume that 1/6 of a minute is 10 seconds

1/6 = 10/60

So there are 60 seconds in a minute so we would multiply 1/3 by 6 to find how many cups she can drink in one minute

1/3 x 6 = 2

So, Dixie can drink 2 cups in one minute.

A company makes 110 bags.
46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?​

Answers

Answer:

51/110

Step-by-step explanation:

No: of bags with buttons but no zips  = 46

No: of bags that have both buttons and zipz = 110-(46+20+39)  =  5

No: of bags with buttons = 46+ 5 = 51

Total no: of bags = 110

Probabilty = 51/110

Is 3(5x - 4) = 15x - 12 a one solution , no solution or infinite solutions

Answers

Answer:

Infinite Solutions

Step-by-step explanation:

3(5x - 4) needs to be simplified

So we multiply 5x by 3

So 3 x 5x = 15x

Then we multiply -4 by 3

3 x -4 = - 12

Put those together we get 15x - 12

The same equation as the one on the right side

So since 15x - 12 = 15x - 12, the x variable can be any number

Jesse measured his height to be 67 inches. His actual height is 68.5 inches. What is the percent error for Jesse's measurem

Answers

Answer:

2.24%

Step-by-step explanation:

Given that :

Actual height = 68.5

Measured height = 67

Percentage error :

(Error value / True value) * 100%

Error = Actual - observed = (68.5 - 67) = 1.5

Percentage error :

(1.5 / 67) * 100%

0.0223880 * 100%

= 2.2388%

Help would be appreciated! (Will give brainliest) Please don’t give me invalid answers on purpose :(

Thanks!



Answers

Answer:

Yes, (0, 1) is the solution of the given inequality.

Step-by-step explanation:

To find whether the given ordered pair is a solution of the linear inequality, we will satisfy the inequality with the coordinates of the ordered pair.

If the inequality is true for the ordered pair it will be the solution.

Inequality is,

y > x - 1

For (0, 1),

1 > 0 - 1

1 > -1

True.

Therefore, ordered pair (0, 1) is the solution of the given inequality.

What is the percent increase from 50 to 69

Answers

Detailed answer:
A change from 50 to 69 represents a positive change (increase) of 38%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
× 100%
Percent change = 69 - 50
|50|
× 100% =
19
50
× 100 = 38% (increase)
Where: 50 is the old value and 69 is the new value. In this case we have a positive change (increase) of 38 percent because the new value is greater than the old value.
This is a simple feat to figure out.

First find the difference between 69 and 50.

69 - 50 = 19


Now to find the decimal, divide 19 by 50 which would equal 0.38. And to find the percentage, move the decimal two spaces to the right.


Answer: 38%
