Nathan used 2(5/6) loaves of bread to make sandwiches for a lunch. He made equal numbers of 4 different types of sandwiches.
What fraction of a loaf of bread did Nathan use for each type of sandwich?

Answers

Answer:

A)

[tex]\displaystyle \frac{1}{12}[/tex]

B)

[tex]\displaystyle \frac{3}{5}[/tex]

C)

[tex]\displaystyle \frac{17}{24}[/tex]

Step-by-step explanation:

Part A)

The Hendersons were traveling 1/3 of the distance on the first day.

However, they had to stop, having only traveled 1/4 of the 1/3 distance.

So, we can multiply the two fractions together.

Therefore, the fraction of the total distance they traveled is given by:

[tex]\displaystyle \frac{1}{4}\times\frac{1}{3}=\frac{1}{12}[/tex]

The Hendersons traveled 1/12 of the total distance.

Part B)

We are assuming the bottle of milk was full at the beginning.

So, at the beginning, there were 1/1 bottle of milk left.

Howie fed a piglet 1/5 of the bottle. So, there is now:

[tex]\displaystyle 1-\frac{1}{5}[/tex]

Of the bottle left.

Making common denominators and subtracting yields:

[tex]\displaystyle =\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]

So, after feeding the piglet, 4/5 of the bottle of milk was still there.

3/4 of the remainder was fed to a calf.

So, the amount that was fed to the calf is 3/4 times 4/5. Therefore:

[tex]\displaystyle \frac{3}{4}\times\frac{4}{5}[/tex]

Multiply:

[tex]\displaystyle =\frac{12}{20}=\frac{3}{5}[/tex]

So, the calf drank 3/5 of the bottle of milk.

Part C)

Nathan used 2 (5/6) loaves of bread to make 4 sandwiches.

First, convert 2 (5/6) to an improper fraction. So:

[tex]\displaystyle 2\frac{5}{6}=\frac{12+5}{6}=\frac{17}{6}[/tex]

Nathan made 4 sandwiches using this. So, we will divide this by 4. Note that this is the same as multiplying by 1/4. Therefore:

[tex]\displaystyle \frac{17}{6}\times\frac{1}{4}=\frac{17}{24}[/tex]

So, Nathan used 17/24 loaves of bread per sandwich.

9. The two figures below have a scale factor of 3 : 2. What is the value of x?

Answers

C I think hope this helps

The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.

The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.

Setting up the proportion, gives:

8/3 = x/2.

To solve for x,  cross-multiply:

[tex]8 \times 2 = 3 \times x.[/tex]

Simplifying the equation, gives:

16 = 3x.

Next, divide both sides of the equation by 3 to isolate x:

x = 16/3.

Therefore, the value of x is 16/3.

⚠️(Long Math Question!)⚠️ PLEASE HELP! THIS IS A TEST! "Jack compared the number of pink rose buses to the number of yellow rose bushes as part of a school project. Jack counted 3 pink rose bushes to every 8 yellow rose bushes. Later in the year, there was a drought and many rose bushes died. New rose bushes were planted to make sure there were the same number of rose bushes before the drought. The new ratio of the number of pink rose bushes to the number of yellow rose bushes is 5:6. After planting new yellow rose bushes there were 180 yellow rose bushes. How many pink and yellow rose bushes were there before the drought? Explain your answer using a tape diagram."

Answers

67.5 pink 180 yellow

The ratio at the beginning of the year was 3:8 then it became 5:6 it says that they planted the rose bushes so there would be the same number as before so that means the ratio was 3:8 with 180 yellow rose bushes, to start solving you have to find out how many yellow rose bushes were represented by a 1 in the ratio, to get that divide 180 by 8 to get 22.5, now you know that a 1 in the ratio is equal to 22.5 bushes, multiply 22.5 by 8 to get the total number of yellow bushes and multiply it by 3 to get the total number of pink bushes so then you get (obviously) 180 total yellow rose bushes and 67.5 total pink rose bushes before the drought, you can check that by simplifying the ratio of 67.5:180 which simplifies into 3:8 which means the numbers check out!

Kayla is given a monthly allowance. She uses 40% of this allowance to purchase a designer bag, and then donates $15 to a charity. If she ends up with $155, which of the equations below can be used to determine what her monthly allowance was?
a. 0.40 X -15 = 155
b. 40 X + 15 = 155
c. 0.60 X - 15 = 155
d. 60 X -15 = 155

Answers

Answer:

A. 0.40x - 15=155

Step-by-step explanation:

40% can be written as 0.40

x = total money earned

-15 from that total

The expression which can be used to calculate her monthly allowance is 0.6X - 15 = 155

Let :

monthly allowance = X

Designer bag purchase = 40% of X = 0.4X

Donation to charity = $15

Total amount left = $155

Percentage left after bag purchase :

1 - 0.4X = 0.6X

0.6X - charity = amount left

Therefore, the required expression is 0.6X - 15 = 155

What is Graph?

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

Daryll is given $30 and spends $1.25 per day on basketball cards.

Larry is given $2 and saves $1.25 per day.

So, to find the same day for both from the graph.

We have to focus on where the lines for two persons intersects, it will the on same day how much money they have.

Hence, the boys have $16 on 11th day.
