MARKING BRAINLIEST! A machine pumps 4 1/2 gallons of water every hour. How many gallons of water does it pump after 2 2/3 hours?

Answers

Answer 1

Answer:

12 Gallons of Water!

___________________________________________________

4.5= 1 hour

9= 2 hours

4.5/3=1.5

So every 1/3 hour equal 1.5 gallons of water!

9+1.5*2= 12

Answer 2

Answer:

Answer:

12 gallons

Step-by-step explanation:

You just multiply both of the numbers.

What Is probability ?

Answers

Final answer:

Probability is a mathematical practice used to measure the likelihood of an event occurring. It is used extensively in various fields to predict the outcome of an experiment or event. The empirical probability is calculated from observed data, while the theoretical probability assumes equal likelihood for all outcomes.

Explanation:

Probability is a mathematical discipline that deals with the chance of an event occurring. It is a measure of certainty or uncertainty related to outcomes and activities, especially in experiments whose results are not predetermined, termed as chance experiments.

Whenever an experiment is carried out, it is referred to as a sample event. The set of all possible results of this experiment is termed as the sample space. The various results or outcomes of the event are subsets of this sample space, and each is associated with a probability.

The empirical probability of an event is calculated by dividing the number of times the event occurs by the total number of opportunities for it to occur. On the other hand, the theoretical probability is computed by dividing the number of expected occurrences of the event by the total number of potential occurrences. In most situations, the probabilities of individual outcomes are assumed to be equal, but this might not always be the case.

Probability is used extensively in various fields from forecasting weather conditions to predicting the outcome of an experiment or an event. For example, genetics, where it helps predict the outcomes of genetic crosses; finance, where it helps a stockbroker determine the rate of return on investments and many more.

The answer is D, i.e. the system was solved via elimination

If you multiply the first equation by 5, the system becomes

$\left \{ {{-5x-10y=35} \atop {5x-6y=-3}} \right.$

If you sum the two equations, you get

$-16y = 32$

And so if you substitute the second equation of system A with this new equation, you'll get system B.

How many solutions does the equation 5p − 4p − 8 = −2 + 3 have? One

Two

None

Infinitely many

Answers

Answer:

Option 1 - One

Step-by-step explanation:

Given : Equation $5p-4p-8=-2+3$

To find : How many solutions does the equation have?

Solution :

Step 1 - Write the equation,

$5p-4p-8=-2+3$

Step 2 - Add 8 both side,

$5p-4p-8+8=-2+3+8$

Step 3 - Solve the like terms

$p=9$

Therefore, The solution of the equation is only one as it is linear equation and the solution is at p=9.

So, Option 1 is correct.

Sarah put raisins into 3/4 of the oatmeal cookie dough she was making. She put nuts into 2/5 of the oatmeal cookie dough with the raisins. What fraction of the entire batch has BOTH raisins and nuts.

Answers

The LCM (lowest common multiple) of 4 and 5 is 20, so convert them so that the denominator is 20:

3/4 = 15/20
2/5 = 8/20

I didn't quite read the question properly, but regardless. Since only 15/20 of the batch has raisins, of which only 8/20 has nuts, we can formulate this equation to solve:

1x15/20x8/20
=3/10
