- A recipe for ice cream calls for 56 fluid
ounces of milk. How many pints of milk are
there in the recipe?

Answers

Answer:

3.5

Step-by-step explanation:

there are 16 ounces in a pint so you do 56 ÷ 16

There are 16 fluid ounces in one pint which means that there are 3.5 pints in 56 fluid ounce.

How to calculate unit price of something?

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Then suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

WE have been given a recipe for ice cream calls for 56 fluid ounces of milk.

We need to find How many pints of milk are there in the recipe.

There are 16 fluid ounces in 1 pint then;

56 ÷ 16

= 3.5

The answer is 3.5 pints because there are 16 fluid ounces in one pint which means that there are two pints in 32 fluid ounces and 3.5 pints in 56 fluid ounce.

Lucia deposits $44.60 into her bank account on Tuesday Morning. Tuesday afternoon, she withdraws to $26.30 and $21.30. Does Luisa have more or less money on Tuesday night than she did on Monday night? Does this equation tell whether Luisa has more or less money on Tuesday night than Monday night? Explain.

Answers

Answer:

Less than

Step-by-step explanation:

Using the data from the question, we can create the following equation to solve this...

44.60 - (26.30 + 21.30) = x

44.60 - (47.60) = x

-3 = x

As you can see Lucia withdrew more money than what she actually deposited which means that her account balance on Tuesday Night is less than what it was on Monday night before the initial deposit. This can all be seen using the above equation which is designed.

is this reasoning inductive or deductive? explain why.

1. all pennies are copper. if your friend gives you a penny, you conclude that the penny is copper colored.

2. all even numbers are divisible by 2. 28 is even. therefore, 28 is divisible by 2.

please help me out with this and also include reasoning! thank you so much!

Answers

Answer:

No. 1 is inductive, cos the evidence is based on proberbility as not all pennies are silver color, since thier color could change over time (fade)

while

No 2 is deductive since all even numners are divisible by 2, there is a full assurance of the outcome.

Answer: The reasonings are deductive. They tried to do a trick question I think.

Step-by-step explanation: There both deductive because the first sentence has a key word which is Conclude. The word might not seem to matter until you look up what  deductive means. Deductive and Inductive are different because one is specifics observation and then draw a conclusion and the other is specifics conclusion  follows a general theory. And the key word in deductive is conclusion in the first sentence it says that you conclude. Deductive means a conclusion that follows a general theory. The deductive is following a general theory which means if the facts are right then the conclusion should  be right. The deductive makes sense in the first because if the facts that all the pennies are copper is true then the penny your friend gave you should be copper. The second sentence same thing if the fact was right then any number that is even can be divisible by 2. So deductive makes sense in both sentences. Inductive makes sense it inside one on the sentences not both. Inductive makes sense inside the first because the person could have seen that the pennies were all made of copper. i think that it being deductive is a better choice that inductive and if you still are confused you can look up "difference between inductive and deductive reasoning" and go to images it should have a blue and pink picture of the definition of them. Sorry I wrote it so long you can just shortened it down for the answer.
