A patient requires an IV of D5W, a 5% solution of dextrose (sugar) in water. To the nearest milliliter, how much D20W, a 20% solution of dextrose in water, must be added to 100 milliliters of distilled water to produce a D5W solution? Please show all work.
Answer:
[tex]A=300ml[/tex]
Step-by-step explanation:
From the question we are told that
5% solution of dextrose sugar in water
20% solution of dextrose in
100 milliliters of distilled water water
Generally in mathematically solving we call A the amount of D20W added
Since 20% of dextrose is needed
[tex]20 \%*100=20milliter[/tex]
Total quantity after addition (100+x)
for DW5% total solution is
[tex]5\% (100+A)= \frac{5}{100}(100+A)[/tex]
[tex]5\% (100+A) =5+0.05A[/tex]
Mathematically
[tex]5+0.05A =20[/tex]
[tex]5+0.05A =20-5[/tex]
[tex]A=\frac{15}{0.05}[/tex]
[tex]A=300ml[/tex]
Therefore the required quantity [tex]A=300ml[/tex]

What is the graph of the function f(x) = the quantity of negative x squared minus 2 x minus 2, all over x minus 2?
Group of answer choices
graph with vertical asymptote of x equals negative 2, and oblique asymptote of y equals negative x
graph with vertical asymptote of x equals 2, and oblique asymptote of y equals x
graph with vertical asymptote of x equals 2, and oblique asymptote of y equals negative x minus 4
graph with vertical asymptote of x equals 5, and oblique asymptote of y equals negative x minus 4
Given:
The function is
[tex]f(x)=\dfrac{x^2-2x-2}{x-2}[/tex]
To find:
The vertical asymptote and oblique asymptote.
Solution:
We have,
[tex]f(x)=\dfrac{x^2-2x-2}{x-2}[/tex]
To find vertical asymptote, equate denominator equal to 0.
[tex]x-2=0[/tex]
[tex]x=2[/tex]
So, the vertical asymptote is [tex]x=2[/tex].
In the given function degree of numerator is greater than denominator so, their is an oblique asymptote. To find oblique asymptote divide the numerator by denominator.
Dividing [tex]x^2-2x-2[/tex] by [tex]x-2[/tex] using synthetic division, we get
2 | 1 -2 -2
2 0
--------------------------
1 0 -2
-------------------------
Here, starting elements of bottom row represent coefficient of quotient and last element of bottom row represents the remainder.
[tex]Quotient=x, Remainder=-2[/tex]
Since, quotient is x, therefore, the oblique asymptote is [tex]y=x[/tex].
Therefore, the correct option is B.
A nest of ants has been growing exponentially in such a way that its population, P, as a function of w weeks is given by P(w)=24, 000(1.063)^w
Matthew claims that the population of ants is growing at a rate of 0.9% per day. Explain why Matthew’s claim is too high of a rate.
Answer:
0.9%
Step-by-step explanation:
Given that:
A nest of ant is represented by the exponential growth function :
P(w)=24,000(1.063)^w
Where w = number of weeks
Recall :
Growth function is generally represented as :
P(t) = A(1 + r)^t
Where ; A is the initial population figure; r = growth rate and t = time
Hence, the growth rate per week of the function given is :
(1 + r) = 1.063
r = 1.063 - 1
r = 0.063
Number of days in a week = 7
Hence, growth rate per day = r /7
0.063 / 7
= 0.009
(0.009 * 100%) = 0.9%

A shop sells shakes for $2 and doublescoop cones for $3. One day they sold 8 more shakes than scoops, and made $156. How many shakes and scoops did they sell?
Answer:
x = 36 and y = 28
Step-by-step explanation:
Let she sells x shakes and y doublescoop cones
One day they sold 8 more shakes than scoops, and made $156.
ATQ,
2x+3y = 156 ..(1)
Also,
x = y+8 ..(2)
Put the value of x from (1) to equation (2)
2(y+8)+3y = 156
2y+16+3y = 156
5y = 156 - 16
5y = 140
y = 28
Put the value of y in equation (2)
x = 28+8
x = 36
Hence, they will sell 36 shakes and 28 doublescoop cones.
I need it step by step please
Answer:
1/2x-3
Step-by-step explanation:
First, make the equation 2y+4x=12 into a linear equation(y=mx+b)
2y=-4x+12
y=-2x+6
From this, you know the slope is -2.
The perpendicular of any slope is going to be the negative inverse.
negative inverse: a/b-->-b/a
so basically flip it and make it negative(make it positive if the original is negative).
So, for -2 it would be 1/2
Now right the equation for the perpendicular line.
y=1/2x+b
b is the y intercept, and since you want to make the line go through (8,1) you have to change the 6 in the original equation.
To do this replace x and y with 8 and 1
1=1/2(8)+b
1=4+b
b=-3
So you plug that into the equation
y=1/2x-3
You put $500 in the bank, where it ears 1.5% simple interest every year. How long until your money will triple?
Answer:
133.33 years
Step-by-step explanation:
Given that:
Principal = $500
Interest rate (r) = 1.5% = 0.015
Triple amount of principal = $500 * 3 = $1500 = final amount (A)
Number of years (t) =?
Using the relation :
A = P(1 + rt)
1500 = 500(1 + 0.015t)
1500 / 500 = 1 + 0.015t
3 = 1 + 0.015t
3 - 1= 0.015t
2 = 0.015t
2 / 0.015 = 0.015t / 0.015
133.333 = t
133.33 years
help please I beg✨✨✨✨✨
=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like [tex]5*\square[/tex]
Then let's say we fill that box with the value 7. We would then have [tex]5*\boxed{7}[/tex]
If we put 3 in the box instead we'll have [tex]5*\boxed{3}[/tex] and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.

15 a b c + 14 a b
Which student wrote the correct expression?
Michelle

Answer:
Peyton in the correct option
Step-by-step explanation:
The correct expression is given by Peyton.
What is expression?An expression is a sentence with a minimum of two numbers or variables and at least one math operation.
Consider if m is any integer, then
gcd (a + m⋅ b, b) = gcd (a, b).
If m is a positive divisor, then
gcd (a/m, b/m) = gcd (a, b)/m.
So, if x and y are prime, then
gcd(x*y, b) = gcd(x, b) * gcd(y, b).
First, find the greatest common factor of the given terms.
The greatest common factor or GCF is the largest factor that all terms have in common.
Then, Factor out the greatest common factor from each term.

Answer: C) Segment PR
====================================================
Explanation:
Let's find the missing angle R. We'll use the idea that all three angles of any triangle always add to 180
P+Q+R = 180
48+83+R = 180
131+R = 180
R = 180-131
R = 49
Here are the three angles of triangle PQR
P = 48Q = 83R = 49The largest angle is Q = 83, so the opposite side PR is the longest side. The longest side of a triangle is always opposite the largest angle.

Answer: x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
8x+10=12x−18
Step 1: Subtract 12x from both sides.
8x+10−12x=12x−18−12x
−4x+10=−18
Step 2: Subtract 10 from both sides.
−4x+10−10=−18−10
−4x=−28
Step 3: Divide both sides by -4.
-4x/-4 = -28/-4
answer: x=7
Answer:
X= 7
Step-by-step explanation:
8x+10 = 12x-18
10= 4x-18
28 = 4x
7 = x
