Patricia donated 1 pint of blood to the blood bank.The lab assistant divided patricia's blood equally into 3 bags.How much blood was in each bag?

Answers

If one pint was in 3 bags equally each bag would have 10.67 ounces.

Each bag contained [tex]\(\frac{1}{3}\)[/tex] pint of blood.

To solve the problem, we need to divide the total amount of blood donated by Patricia equally into 3 bags. Patricia donated 1 pint of blood.  

Since there are 3 bags, we divide 1 pint by 3 to find out how much blood is in each bag. The division is straightforward:

[tex]\[ \frac{1 \text{ pint}}{3 \text{ bags}} = \frac{1}{3} \text{ pint per bag} \][/tex]

Therefore, each bag contains [tex]\(\frac{1}{3}\)[/tex] pint of blood. This is the simplest form of the fraction, and there is no need to convert it to a different unit or simplify it further. The answer is [tex]\(\frac{1}{3}\)[/tex] pint per bag.

Part 1:Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime factors? Why? Part 2: Give an example of how prime factorization could be used in the real world. Part 3: View and comment on the work of at least two other students. Explain why you agree or disagree with their ideas.

Answers

Part 1:Is it possible for a composite number to have more than one prime factorization?
Answer: No.

Is it possible for a number to have no prime factors? Why?
Answer: Yes. The number 1 has no prime factors, and 1 is not prime.

Part 2: Give an example of how prime factorization could be used in the real world.
Answer: A carpenter needs to add two lengths to cut a piece of wood. One length is 5 1/16 inch, and the other length is 3 3/10 in. By using prime factors of 16 and 10, he can find the least common denominator of 16 and 10, and he can add the lengths together.

A composite number has only one prime factorization, and 1 is the only number without prime factors. Prime factorization plays a crucial role in cryptography. Peer work review would focus on understanding and accuracy but cannot be provided without specific student examples.

No, a composite number cannot have more than one prime factorization due to the Fundamental Theorem of Arithmetic, which states that every integer greater than 1 either is a prime number itself or can be factored into prime numbers in exactly one way, ignoring the order of the factors. On the other hand, the only number that has no prime factors is 1, as it is neither prime nor composite.

One real-world application of prime factorization is in cryptography, particularly in algorithms like RSA, which is used to secure data transmission over the internet. The difficulty in factoring large numbers into primes is what makes this method effective for encrypting sensitive information such as credit card numbers.

Without specific examples of the work of other students, it is not possible to provide a review. Typically, when reviewing peer work, one would assess the correctness of their understanding of prime factorization and its application in real-world scenarios, as well as the clarity and accuracy of their explanations.

To find the y-intercept, substitute in 0 for x and solve for y.
-6(0) + 3y = 18.9 
3y = 18.9
y = 18.9/3
y = 6.3 (0,6.3) <-- Your x-intercept is (0,6.3)

If this helped, please mark me brainliest, thank you and if you need more help, feel free to message me! 


Final answer:

The x-intercept of the line −6x+3y=18.9 is −3.15, and the y-intercept is 6.3. The point-slope form of the line with slope −14 passing through (-2, 9) is y−9=−14(x+2). The ordered pairs that solve the inequality y∓4x≥−5 are (1, −1), (−4, 2), and (−2, 1).

Explanation:

To find the x-intercept and y-intercept of the line described by the equation −6x+3y=18.9, we can set each variable to zero in turn and solve for the other:

For the x-intercept, set y = 0:
−6x = 18.9 → x = 18.9 / (−6) → x = −3.15For the y-intercept, set x = 0:
3y = 18.9 → y = 18.9 / 3 → y = 6.3

Therefore, the x-intercept is −3.15 and the y-intercept is 6.3.

For the point-slope form of the line with slope −14 that passes through the point (−2, 9), we use the formula y – y1 = m(x – x1), where m is the slope and (x1, y1) is the point the line passes through. This gives us:

y – 9 = −14(x – (−2)) → y – 9 = −14(x + 2)

The correct option is C. y – 9 = −14(x + 2).

To determine which ordered pairs are solutions to the inequality y – 4x ≥ −5, we test each pair by substituting the x and y values into the inequality:

(4, 0): −4 – 4(4) ≥ −5 → −4 – 16 ≥ −5 is false.(1, −1): −1 – 4(1) ≥ −5 → −1 – 4 ≥ −5 is true.(−4, 2): 2 – 4(−4) ≥ −5 → 2 + 16 ≥ −5 is true.(−2, 1): 1 – 4(−2) ≥ −5 → 1 + 8 ≥ −5 is true.(5, −2): −2 – 4(5) ≥ −5 → −2 – 20 ≥ −5 is false.

The ordered pairs that are solutions to the inequality are (1, −1), (−4, 2), and (−2, 1).

David gained 16 pounds over the winter. he went on a diet and lost 25 pounds. then he regained 4 pounds and weighed 177 pounds. how much did he weigh​ originally?

Answers

let x be the weight of David so 

x+16-25+4 = 177

x-5=177

x= 177+5= 182 pound
Final answer:

David's original weight was 182 pounds, as we determined by retracing his weight changes in reverse order.

Explanation:

To find out how much David originally weighed, we need to work backwards from his ending weight, taking his weight changes into account. Currently David weighs 177 pounds. However, before gaining the last 4 pounds, he would have weighed 177 - 4 = 173 pounds.

Going back further, before losing 25 pounds, he would have weighed 173 + 25 = 198 pounds. Finally, before David gained 16 pounds over the winter, his original weight would have been 198 - 16 = 182 pounds.

So, David's original weight was 182 pounds.

Two sides of an equilateral triangle have lengths x+2 and -2x+20 Which could be the length of the third side: 14-x or 2x+4?

a. 2x + 4 only
b. both 14 - x and 2x + 4
c. 14 - x only
d. neither 14 - x nor 2x + 4

Answers

an equilateral triangle has 3 equal sides by definition.

so we know that x+2 = -2x+20 because we're told that those are both lengths of the triangle's sides. let's solve for x.

x+2 = -2x + 20
add 2x to both sides.
3x + 2 = 20
subtract 2 from both sides.
3x = 18
divide both sides by 3.
x = 6

now, let's find the length of the sides. plug 6 into one side, which is x+2.
6+2 = 8. so each side's length must be equal to 8. let's just check to make sure we didn't make a mistake. if this is correct, then -2x + 20 should also = 8.

-2(6) + 20
-12 + 20
8.

so we know that the sides = 8. let's see if 14 - x or 2x+4 are equal to 8 when we plug in 6 for x.

14 - 6 = 8. so 14-x could be a length for a side.

2(6) + 4 = 12 + 4 = 16. so 2x + 4 can not be a length for a side.

the answer is 14 - x only, or C.

What is the coefficient of x7 in the expansion of (1 + x)11?

Answers

You can choose to expand the equation to find the coefficient of x7 but that would take a lot of time. Here is a useful tactic that can help; 

11C(something)(1)(x)⁷ ----> This gives the coefficient of x⁷
11C7(1)⁴(x)⁷ ----> You know that pascal's triangle is equal on both sides 
11C7×1⁴ = coefficient of x⁷ (just ignore x⁷)
330x1⁴=330 

This means that the coefficient of x⁷ is 330. You can double check by expanding the equation. If you do not understand what I did there, you can ask me how I got to the solution. 

Hope I helped :) 

Final answer:

Using the binomial theorem, the coefficient of x⁷ in the expansion of (1 + x)¹¹ is found by calculating '11 choose 7', which is 330.

Explanation:

The coefficient of x⁷ in the expansion of (1 + x)¹¹ can be found using the binomial theorem. To find the coefficient of x⁷, we look for the term that comes from choosing x seven times in the expansion. This corresponds to the 8th term, because the terms are indexed from 0, where the binomial coefficient is found by calculating "11 choose 7" or C(11, 7).

To calculate "11 choose 7", use the formula:
C(n, k) = n! / [k!(n-k)!], which gives us:

C(11, 7) = 11! / [7!(11-7)!] = 11! / (7!4!) = (11×10×9×8) / (4×3×2×1) = 330

Therefore, the coefficient of x⁷ in the expansion of (1 + x)¹¹ is 330.

Since dimensions cannot be negative, we have to use 11/2 or 5.5 

The Width is 5.5ft , length is (2(5.5)-3)=8 ft

Hope I helped :) 

Final answer:

To find the dimensions of a rectangle where the length is 3 ft less than twice the width and the area is 44 ft², we use the relationship between the width and length to set up a quadratic equation. After solving for the width, we use that width to find the length and confirm that the area is correct.

Explanation:

To find the dimensions of the rectangle with an area of 44 ft2, we need to set up an equation based on the given relationships. Let's denote the width of the rectangle as w and the length as l. According to the problem, the length is three feet less than twice the width, so we have l = 2w - 3. The area of the rectangle is the product of its width and length, so the equation to calculate the area is w × l = 44. Substituting the expression for l into this equation yields w × (2w - 3) = 44.

Solving this quadratic equation, we distribute the width and get 2w2 - 3w = 44. By moving all terms to one side, we have 2w2 - 3w - 44 = 0. Factoring the quadratic equation or using the quadratic formula will result in two values for w, where one will be the width and the corresponding l will be the length when plugged into l = 2w - 3.

Let's find the dimensions:

Width: wLength: 2w - 3

Once the values are calculated, we can confirm that the width and length provide an area of 44 ft2.

Therefore, the width of the rectangle is w= 5.5 feet.

Now, we can find the length (l):

l=2w−3=2(5.5)−3=11−3=8

So, the length of the rectangle is l=8 feet.

Which inequalities model the situation? Select each correct answer.
x+y≤30
x>0
x+y<30
y≥12
y>12

Answers

Since they are FEWER than 30 total cones, the sum of x small cones and y large one must be LESS THAN 30: x+y <30
He needs AT LEAST a dozen (12), so that means that 12 will work or more than 12:
[tex]y \geqslant 12[/tex]

Answer: The correct options are,

x+y < 30

y ≥ 12

Step-by-step explanation:

Here, x represent the number of small cones and y represent the number of large cones.

∵ Large cones are at least 12,

y ≥ 12,

Now, total cones = x + y

∵ There are fewer than 30 cones,

I.e.  x + y < 30,

Now, number of cones can not be negative,

x, y ≥ 0
