Prime factor of 2080
Answer:
2 x 2 x 2 x 2 x 2 x 5 x 13
Step-by-step explanation:
The Prime Factorization is:
2 x 2 x 2 x 2 x 2 x 5 x 13
In Exponential Form:
25 x 51 x 131
CSV Format:
2, 2, 2, 2, 2, 5, 13
The prime factors of 2080 are 2, 2, 2, 2, 5, and 13.
Divide 2080 by the smallest prime number, which is 2:
2080 ÷ 2 = 1040
Continue dividing by 2:
1040 ÷ 2 = 520
Continue dividing by 2:
520 ÷ 2 = 260
Continue dividing by 2:
260 ÷ 2 = 130
Continue dividing by 2:
130 ÷ 2 = 65
Now, 65 is not divisible by 2.
Move to the next prime number, which is 5:
65 ÷ 5 = 13
13 is a prime number.
So, the prime factors of 2080 are 2, 2, 2, 2, 5, and 13. In exponential form, this can be written as 24 * 5 *13.

Loc weighs 14 pounds. The HCP prescribes an IV infusion of 5% dextrose in 1/4 normal saline to be infused at 8mL/kg/hr. How many mL of the prescribed solution should the nurse infuse each hour?
To infuse the prescribed solution each hour, the nurse should administer 51 mL.
Explanation:To calculate the amount of solution that should be infused each hour, we first need to calculate the weight of the patient in kilograms. We can do this by converting the weight from pounds to kilograms using the conversion factor of 0.4536 kg/pound. So, the weight of the patient in kilograms is 14 pounds x 0.4536 kg/pound = 6.3504 kg. Next, we multiply the weight in kilograms by the infusion rate of 8 mL/kg/hr to find the total volume of solution to be infused each hour. Thus, the nurse should infuse 6.3504 kg x 8 mL/kg/hr = 50.8032 mL, which can be rounded to 51 mL each hour.

Answer:
The answer is actually (-4, -0.5, 1) in order from least to greatest.
Step-by-step explanation:
A system of equation is a collection of more than one equation
The system of equations to determine the roots of [tex]2x^3 + 4x^2 - x + 5 = -3x^2 + 4x + 9[/tex] are [tex]y = 2x^3 + 4x^2 - x + 5[/tex] and [tex]y= -3x^2 + 4x + 9[/tex]The roots of the polynomial equation are -0.5 and 1The equation is given as:
[tex]2x^3 + 4x^2 - x + 5 = -3x^2 + 4x + 9[/tex]
Split the equation to a system of equations:
[tex]y = 2x^3 + 4x^2 - x + 5[/tex]
[tex]y= -3x^2 + 4x + 9[/tex]
So, the system of equations to determine the roots of [tex]2x^3 + 4x^2 - x + 5 = -3x^2 + 4x + 9[/tex] are [tex]y = 2x^3 + 4x^2 - x + 5[/tex] and [tex]y= -3x^2 + 4x + 9[/tex]
See attachment for the graphs of [tex]y = 2x^3 + 4x^2 - x + 5[/tex]

On a certain hot summer's day, 391 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $752.75. How many children and how many adults swam at the public pool that day?
Final answer:
there were 127 children and 264 adults.
Explanation:
To solve this problem, we use a system of equations. Let's denote the number of children as C and the number of adults as A. We know two facts: the total number of people is 391, and the total amount of money collected is $752.75. Therefore, we have the equations:
C + A = 3911.25C + 2.25A = 752.75To solve this system, we first multiply the first equation by 1.25 to align the coefficient of C with the second equation:
1.25(C + A) = 1.25(391)1.25C + 1.25A = 488.75Next, we subtract this result from the second equation to eliminate C, leaving an equation in terms of A only:
2.25A - 1.25A = 752.75 - 488.75
A = (264) / 1 = 264
Substituting the value of A into the first equation, we find the value of C:
C + 264 = 391
C = 127
Therefore, there were 127 children and 264 adults who swam at the public pool that day.
Simplify (2 3/5) divided by (-3 3/4)
Rewrite the numbers as improper fractions:

-3 3/4 = -15/4
Now you have 13/5 divided by -15/4
When dividing fractions flip the second one over and then multiply:
13/5 x -4/15 = (13 x -4) / (5 x15) = -52/75
Leah wrote 2 different fractions with the same denominator.Both fractions were less than 1. Can their sum equal 1? Can their sum be greater than 1? Explain.
Answer:
1. Yes
2. Yes
Step-by-step explanation:
Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.
1. Can their sum equal 1?
Let Leah fractions be [tex]\dfrac{6}{7}[/tex] and [tex]\dfrac{1}{7}.[/tex] Both these fractions have the same denominators and are less than 1. Find their sum:
[tex]\dfrac{6}{7}+\dfrac{1}{7}=\dfrac{7}{7}=1[/tex]
2. Can their sum be greater than 1?
Let Leah fractions be [tex]\dfrac{6}{7}[/tex] and [tex]\dfrac{5}{7}[/tex]. Both these fractions have the same denominators and are less than 1. Find their sum:
[tex]\dfrac{6}{7}+\dfrac{5}{7}=\dfrac{11}{7}=1\dfrac{4}{7}>1[/tex]
Two fractions with the same denominator can sum to 1 if their numerators add up to the denominator, or they can sum to more than 1 if their numerators together exceed the denominator. This is based on the concept of adding fractions where only the numerators are summed.
Leah wrote two different fractions with the same denominator, and both were less than 1. Can their sum equal 1? Can their sum be greater than 1? The answer to both questions depends on the value of the numerators. Fractions represent parts of a whole. For two fractions with the same denominator to have a sum of 1, the numerators must add up to the denominator. If their sum is greater than the denominator, then the total sum would be greater than 1.
For example, if we have fractions ½ and ¾, their sum is ½ + ¾ = ¾ which is less than 1. However, if we have ¾ and ¾, the sum equals 6/4, which reduces to 1½, a sum greater than 1.
In conclusion, two fractions with the same denominator and each less than 1 can sum to 1 if the numerators total the denominator, or can sum to greater than 1 if the numerators together exceed the denominator. An important aspect of adding fractions is that we only add the numerators and never the denominators.
3x+2y=-10
2x-5y=3
Solve using elimination
Answer:
look at the picture shown
The solution to the system of equations 3x+2y=-10 and 2x-5y=3 using the elimination method is x = -44/19 and y = -29/19.
Explanation:To solve the system of equations 3x+2y=-10 and 2x-5y=3 using the elimination method, we need to multiply the equations by respective constants so that a variable gets eliminated when we add or subtract them. Let's try to eliminate y.
Multiply the first equation by 5 (the coefficient of y in the second equation) and the second equation by 2 (the coefficient of y in the first equation):
5*(3x+2y) = 5*(-10)
2*(2x-5y) = 2*3
15x + 10y = -50
4x - 10y = 6
Add the two equations:
(15x + 10y) + (4x - 10y) = -50 + 6
19x = -44
Divide both sides by 19 to solve for x:
x = -44/19
x = -44/19
Now substitute x back into one of the original equations to solve for y:
3x + 2y = -10
3*(-44/19) + 2y = -10
Multiply 3 by -44/19:
-132/19 + 2y = -10
Now solve for y:
2y = -10 + 132/19
2y = (-190/19) + (132/19)
2y = -58/19
Divide by 2:
y = -58/38
y = -29/19
Therefore, the solution to the system of equations is x = -44/19 and y = -29/19.

Area of a rectangle is 100 sq ft. The length is 10 ft longer than twice it’s width. What is the length and the width.
The length of the rectange is 20ft and width of the 5ft.
Step-by-step explanation:
Let us consider a rectangle and its area is known to be 100 sq ft.
We are given the information that the length of the rectangle is 10ft longer than twice its width.
⇒Length l = 2w+10.
Where w is the width of the rectangle.
The formula for area of the rectangle A = length × width.
A= (2w+10)×w.
100 = [tex]2w^2+10w[/tex].
0=[tex]2w^2+10w-100[/tex].
Thus it forms an quadratic equation we have to solve for the solution.
0=(2w-10)(w+10).
2w-10=0. w+10=0.
2w=10. w=-10. (negative value cannot be choosed.)
w=[tex](\frac{10}{2} )[/tex].
w=5ft.
Thus width is is 5 ft.
Length = 2(5)+10.
=10+10.
=20ft.
Thus the length is 20ft.

Step-by-step explanation:
A data set that has a mean absolute deviation of 0 means the average difference between the elements in a data set and mean of the same data set is very less.
What is Mean absolute Deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
As we know the mean absolute deviation is the average distance between each data point and the mean.
If more than 50% of your data have identical values, your MAD will equal zero.
Also, the mean absolute deviation of a dataset is the average distance between each data point and the mean.
If the mean absolute deviation (MAD) is close to 0,it means the average difference between the elements in a data set and mean of the same data set is very less.
Thus, the average difference between the elements in a data set and mean of the same data set is very less.

The value of y varies directly as the square of x and y=36 when x=3. What is y when x=4?
Answer: y = 64
Step-by-step explanation:
y <> x² ----------------------- 1
y = kx² ----------------------- 2
36 = 3²k
36 = 9k
K = 36/9
= 4.
To find y when x = 4, we substitute for x in equation 2
y = kx²
y = 4²k
y = 16 x 4
y = 64
The value of y, which varies directly as the square of x, is determined by first identifying the constant of variation from the given values, in this case, y = 36 when x = 3. The constant is found to be 4. Using this constant (k), when x is 4, y will be 64.
Explanation:The value of y varies directly as the square of x, which is represented mathematically as y = kx², where k is the constant of variation. Using the given that y = 36 when x = 3, we can determine k by substituting these values into the equation. Thus, k = y/x² = 36/9 = 4. Now, having the value for k, we can find y when x = 4 by substituting these values into the equation: y = kx² = 4×16 = 64. Therefore, y equals 64 when x equals 4 in the given relation.
