Please create your own real-world scenario that requires the use of the distributive property.
Write the problem and show all the steps needed to find the answer.

Then include a description on how this problem uses the distributive property.

Please help me with this, thanks so much in advance!

Answers

Answer 1
My use of distributive is that you have 3 cows and 6 lambs then you have to kill them for meat. But the problem is you have to get twice the meat you usually get. So what do you do? You just cut the meat half the thickness you usually cut. It goes like this 2(3+6)= 18. First add the 3 and 6 together get 9 then multiply 9 by 2 and get 18.

I need help with the second one!!

Answers

since they want to make 1 1/2 of the recipe that means that it is half of the recipe three times so you need to multiply 5/16 by three

For the second one, they are wanting to make 1 and 1/2 the original recipe. This means it is a 50% increase from the original recipe. So, we should multiply 1 and 1/2 by 5/8.
[tex]1 \frac{1}{2} * \frac{5}{8} = \frac{3}{2} * \frac{5}{8}= \frac{15}{16} [/tex]
So, they will need 15/16 cups of coca for the new recipe.

The total imports of petroleum ( in millions of barrels per day) in a given year is approximated by the polynomial 40x^3 -526x^2+2089x+6056, where x represents the number of years since 1975. The corresponding total of exports of petroleum is -x^3 +13x^2 +29x+189. Write a polynomial that represents how many more barrels per day were imported than exported in a given year.

Answers

What your going to do is multiply the numbers and get your answer and multiply them all by 2.
In this question, you are given the polynomial of the import (40x^3 -526x^2+2089x+6056) and the export (-x^3 +13x^2 +29x+189). You are asked the difference between import and export. Then you need to subtract the export value from import value. The calculation would be:

40x^3 -526x^2+2089x+6056 - (-x^3 +13x^2 +29x+189)=
40x^3 -526x^2+2089x+6056 + x^3 -13x^2 - 29x -189=
41x^3 -539x^2+2060x+5867 

Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x) George reads 200 pages in 40 minutes. x g(x) 4 −8 4 10 4 28

Answers

The answer wold be The relationship between slopes cannot be determined 

Therefore, since the slope of f(x) is defined and g(x) has an undefined slope, the correct option is: d) The function f(x) has a larger slope.

To determine the slopes of the functions f(x) and g(x), we need to calculate the rate of change or the slope of each function.

The slope of a function represents how much the output (y-value) changes for a given change in the input (x-value).

For function f(x), the rate of change can be calculated as follows:

[tex]\[ \text{Slope of } f(x) = \frac{\text{Change in } y}{\text{Change in } x} = \frac{200 \text{ pages}}{40 \text{ minutes}} = 5 \text{ pages/minute} \][/tex]

Now, let's calculate the slope for function g(x) using the given data points:

[tex]\[ \text{Slope of } g(x) = \frac{\text{Change in } y}{\text{Change in } x} = \frac{28 - (-8)}{4 - 4} = \frac{36}{0} \][/tex]

As the denominator is zero, the slope for g(x) is undefined.

Answers

1.) 28- all numbers listed are divisible by 28
2.) 15 (30/2, 45/3, and 75/5)

The gcf for the numbers 28, 56 and 84 is 28

Since

28: 1, 2, 4, 7, 14, 28

56: 1, 2, 4, 7, 8, 14, 28, 56

84: 1,2,3,4,6,7,12,14,21,28,42,84

Since the biggest number they all have is 14 so the gcf is 14.

The gcf for the numbers 30, 45, and 75 is 15

30: 1,2,3,5,6,10,15,30

45: 1,3,5,9,15,45

75: 1,3,5,15,25,75

Since the biggest number they all have is 15 so the gcf is 15.

how many times longer is the baby alligator 3/4 ft than the baby 2/15ft

Answers

1. Find common denominators so the common denominator is 60
2. Multiply the numerator by how much the denominator goes into the common denominator so 3 x 15 and 2 x 4
3.You get left with 45/60 - 8/60
4. Subtract the numerators to get 37/60
5. You can't simplify it so the final answer is 37/60

We need to find how much longer is the baby alligator compared to a baby.

The baby alligator is [tex]\dfrac{45}{8}[/tex] times longer than the baby.

The baby alligator is 3/4 ft long.

The baby is 2/15 ft long.

According to the question

[tex]\dfrac{3}{4}=\dfrac{2}{15}x[/tex]

The value of x will give us how many times is the baby alligator longer by

[tex]x=\dfrac{\dfrac{3}{4}}{\dfrac{2}{15}}\\\Rightarrow x=\dfrac{3\times 15}{4\times 2}\\\Rightarrow x=\dfrac{45}{8}[/tex]

So, the baby alligator is [tex]\dfrac{45}{8}[/tex] times longer than the baby.

what does this expression represent 12f+24

Answers

Depending on the word problem, the f in this expression could represent a cost or the amount of something bought for $12. The 24 in this expression could represent the cost to get into somewhere or another cost.

Hope this helps!! :)

Answer:

This is an algebraic expression which means that 12 multiplied by the value of a variable "f", plus 24 would give an integer.

Step-by-step explanation:

This expression can be solved when the value of f is known. Thus its solution is dependent on the known value of "f".

So, assuming the value of f is 2, then the answer would have been 48.

At 1 pm, there were 16 seagulls on the beach. At 3 pm, there were 40 seagulls. What is the constant rate of change?

Answers

The answer is (change of amount) / (change of time). For the change of amount, the numerator is 40 seagulls - 16 seagulls, leaving a total of 24 seagulls. For the change of time, the denominator is 3 pm - 1 pm, leaving a total of a 2 hour difference. The answer becomes 24 seagulls / 2 hours, or 12 seagulls per hour when simplified.

a grandmother is making clothes for her three granddaughters. She'll make a jacket and one other item for each granddaughter. The three other items will be exactly the same. A jacket takes 1 5/8 yards of fabric. She had 10 yards of material of. She's trying to figure out how much fabric she has for each of the three extra items. Write a number sentence to represent the situation of the total fabric use.

Answers

If every item will be the same then you would multiply 15/8x4= 7 1/2.
The total amount of fabric use is 7 1/2

The required number to represent the situation is 67/24.

What is the ratio of two numbers?

The ratio of two numbers a and b can be written as a : b = a/b.

The ratio of two quantities is the unit rate of one quantity with respect to the other.

Given that,

The cloth required for jacket is 1(⁵/₈) = 13/8 yards.

Then the remaining cloth for the three other items = 10 - 13/8 = 67/8 yards.

Now, the cloth for each of the items is calculated by taking the ratio as,

(67/8)/3

= 67/24

Hence, the yards of cloth available for each of the item is given as 67/24 yards.

what is -4/5 + 3/20 in simplest form

Answers

-4/5 = -16/20, so the new expression is (-16/20)+(3/20)
then, -16 + 3 is -13, so the solution is -13/20
-4/5 + 3/20 = 3/20 - 4/5

To subtract 2 fractions, they both need to have the same denominator.
Since 5 is one of the divisors of 20, we can just multiply the numerator and denominator of 4/5 by 4.
4/5 = (4*4) / (5*4) = 16/20

P.S. when the denominators of both fractions don't have any relation, you multiply the numerator and denominator of the first fraction by the denominator of the second, and the numerator and denominator of the second by the denominator of the first.

3/20 - 4/5 = 3/20 - 16/20

Now you just subtract the numerators:
3/20 - 16/20 = (3-16)/20 = -13/20

So -4/5 + 3/20 = -13/20
