Write a subtraction problem involving pounds and ounces. Solve the problem and show your work.
Answer: Edgur eats 12 ounces of popcorn. Before he ate any, he had 2 pounds of popcorn. How much popcorn, in ounces, of popcorn does Edgur have now? Edgur has 20 ounces of popcorn.
Step-by-step explanation:
Pounds to ounces: 1 pound = 16 ounces.
2 * 16 = 32.
He ate 12 of those ounces. 32 - 12 = 20.
Final answer:
To solve a problem involving subtraction of pounds and ounces, convert everything to ounces, subtract, and convert back if necessary. In this example, after removing 3 pounds 5 ounces from 9 pounds 8 ounces, the remaining weight is 6 pounds 3 ounces.
Explanation:
Let's create a subtraction problem involving pounds and ounces. Imagine you have a sack of potatoes weighing 9 pounds 8 ounces, and you remove a bag of potatoes weighing 3 pounds 5 ounces. How much does the sack of potatoes now weigh?
First, we need to ensure that both weights are in the same units. We have:
Initial weight: 9 pounds 8 ounces
Weight removed: 3 pounds 5 ounces
To subtract these weights, we will convert pounds to ounces for each weight, then subtract, and finally convert back to pounds and ounces if necessary.
Convert 9 pounds to ounces: 9 × 16 = 144 ounces
Therefore, the initial weight in ounces is 144 ounces + 8 ounces = 152 ounces.
Convert 3 pounds to ounces: 3 × 16 = 48 ounces
The weight removed in ounces is 48 ounces + 5 ounces = 53 ounces.
Subtract the smaller weight from the initial weight: 152 ounces - 53 ounces = 99 ounces
Now we convert 99 ounces back to pounds and ounces. Since 1 pound is 16 ounces:
99 ÷ 16 = 6 pounds with a remainder of 3 ounces.
So, the sack of potatoes now weighs 6 pounds 3 ounces.
For a group experiment, your science class measured the fine-particulate concentrations in the air at random places around campus, and estimated a sample average of 22 μg/m3 (micrograms per cubic meter). If 144 readings were taken, and the standard deviation of the sample measurements was 4 μg/m3, you are 99.7% confident that actual concentration of fine particulates at the school is
Answer:
The class interval is from (22.8748 ug/m³ - 21.1252 ug/m³).
Step-by-step explanation:
Given : Sample size(n)= 144
Sample mean [tex]\mu= 22 ug/m^3[/tex]
Standard deviation [tex]\sigma=3.5 ug/m^3[/tex]
To find : 99.7% confident that actual concentration of fine particulates at the school is?
Solution :
The formula for confidence interval is
[tex]CI=\mu \pm z\times\dfrac{\sigma}{\sqrt{n}}[/tex]
Substituting the values in the formula,
[tex]CI=22 \pm 3\times\dfrac{3.5}{\sqrt{144}}[/tex]
[tex]CI=22 \pm 3\times\dfrac{3.5}{12}[/tex]
[tex]CI=22 \pm 3\times 0.2916[/tex]
[tex]CI=22 \pm 0.8748[/tex]
[tex]CI=22+0.8748, 22-0.8748[/tex]
[tex]CI=22.8748, 21.1252[/tex]
Therefore, The class interval is from (22.8748 ug/m³ - 21.1252 ug/m³).

marcel said he can find 52 times 10 by adding a 0 to the end of 52 to get 520 is he correct?
Answer:
Yes he is Correct
Step-by-step explanation:
When multiply with numbers like 10,100,1000 ect or even like 20,200,2000 then you have to break it down. Since multiply by zero equals 0 anyways you will only have to focus on the number that is in front of it. And just and the zeros to the back of the number.
Answer:
Yes he is correct
Step-by-step explanation:
Whenever we are multiplying any number with 10 or multiples of ten we simply add the zeros to the end of that number.
For example:
134 x 10 = 1340
As you can see, to get the answer, you simply need to add 0 to the end of 134
Also 10 x 10 = 100
To get the answer we simply added zero to the end of ten which then give us 100
12 x 10= ? all you need to do is to add zero to the end of 12 which will give us 120
13 x 100 =? In this case, since the zeros are two, you will simply add two zeros to the end of 13 which will give you the answer 1300
So Marcel can find 52 times 10 by simply adding a 0 to the end of 52 to get 520 as the correct answer.

What is the factorization of 729^15+1000?
Answer:
The factorization of [tex]729x^{15} +1000[/tex] is [tex](9x^{5} +10)(81x^{10} -90x^{5} +100)[/tex]
Step-by-step explanation:
This is a case of factorization by sum and difference of cubes, this type of factorization applies only in binomials of the form [tex](a^{3} +b^{3} )[/tex] or [tex](a^{3} -b^{3})[/tex]. It is easy to recognize because the coefficients of the terms are perfect cube numbers (which means numbers that have exact cubic root, such as 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000, etc.) and the exponents of the letters a and b are multiples of three (such as 3, 6, 9, 12, 15, 18, etc.).
Let's solve the factorization of [tex]729x^{15} +1000[/tex] by using the sum and difference of cubes factorization.
1.) We calculate the cubic root of each term in the equation [tex]729x^{15} +1000[/tex], and the exponent of the letter x is divided by 3.
[tex]\sqrt[3]{729x^{15}} =9x^{5}[/tex]
[tex]1000=10^{3}[/tex] then [tex]\sqrt[3]{10^{3}} =10[/tex]
So, we got that
[tex]729x^{15} +1000=(9x^{5})^{3} + (10)^{3}[/tex] which has the form of [tex](a^{3} +b^{3} )[/tex] which means is a sum of cubes.
Sum of cubes
[tex](a^{3} +b^{3} )=(a+b)(a^{2} -ab+b^{2})[/tex]
with [tex]a= 9x^{5}[/tex] y [tex]b=10[/tex]
2.) Solving the sum of cubes.
[tex](9x^{5})^{3} + (10)^{3}=(9x^{5} +10)((9x^{5})^{2}-(9x^{5})(10)+10^{2} )[/tex]
[tex](9x^{5})^{3} + (10)^{3}=(9x^{5} +10)(81x^{10}-90x^{5}+100)[/tex]

Rewrite sin^4x so that it involves on the first power of cosine
Use the half-angle identities.
[tex]\sin^2x=\dfrac{1-\cos2x}2[/tex]
[tex]\implies\sin^4x=\left(\dfrac{1-\cos2x}2\right)^2=\dfrac{1-2\cos2x+\cos^22x}4[/tex]
[tex]\cos^2x=\dfrac{1+\cos2x}2[/tex]
[tex]\implies\sin^4x=\dfrac{1-2\cos2x+\frac{1+\cos4x}2}4=\dfrac{3-4\cos2x+\cos4x}8[/tex]
sin^4(x) can be expressed in terms of cosine as (1 - cos^2(x))^2.
Rewrite sin^4(x) in terms of cosine by using the Pythagorean identity for trigonometric functions, which relates sin^2(x) and cos^2(x):
sin^2(x) + cos^2(x) = 1
Now, solve for sin^2(x):
sin^2(x) = 1 - cos^2(x)
Now, square sin^2(x) to get sin^4(x):
(sin^2(x))^2 = (1 - cos^2(x))^2
sin^4(x) = (1 - cos^2(x))^2
So, sin^4(x) can be expressed in terms of cosine as (1 - cos^2(x))^2.

What is the difference between a relation
and a function? Is every relation a function? Is every
function a relation? Explain.
Answer:
Not all relationships are functions, but all functions are also relationships
Step-by-step explanation:
A relationship is a correspondence between two sets of values.
A relationship assigns values from an output set called range to a set and input called a domain.
On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).
In other words, if an input value [tex]x_1[/tex] is assigned two or more output values [tex]y_1[/tex], [tex]y_2[/tex], [tex]y_3[/tex] .. then the relationship is not a function. This means that not all relationships are functions.
[tex]y=\±\sqrt{x} +3[/tex] is a relation but it is not a function.
because when x = 4 then y = 1 and y = 5.
Not all relationships are functions, but all functions are also relationships
Final answer:
A relation is a set of ordered pairs, while a function is a relation where each input value is associated with only one output value. Not every relation is a function, but every function is a relation.
Explanation:
A relation is a set of ordered pairs where each input value is associated with one or more output values. On the other hand, a function is a relation where each input value is associated with only one output value.
Not every relation is a function. For example, the relation {(1,2), (1,3), (2,4)} is not a function because the input value 1 is associated with two different output values (2 and 3). However, every function is a relation because it establishes a relationship between the input and output values.

X^2+16x+48=0 it says to solve each quadratic equation by factoring.
Answer:
x = -4 and x = -12
Step-by-step explanation:
x^2 + 16x + 48 = 0 is to be factored.
Note that 48 is the product of 4 and 12 and that the sum of 4 and 12 is 16.
Therefore,
x^2 + 16x + 48 = 0 in factored form is:
(x + 4)(x + 12) = 0, so that x + 4 = 0 → x = -4, and
x + 12 = 0 → x = -12
Answer:
(x + 4) (x + 12)
Step-by-step explanation:
to factor x² + 16x + 48 = 0, you need to find 2 numbers that when multiplied together give you 48 and when added together give you 16
you can list the factors of 48 and see what adds up together to give you 16, but here is a hint:
the numbers probably end in a 2, 4, 0, 6, 5, or 1, as a pair of these numbers added together give us 6. i looked at a factor chart and saw that 12 and 4 that when added together, give us 16 and when multiplied, give us 48
in factored form it looks like the following:
(x + 4) (x + 12)
this would be the answer in factored form
