Answer:
C) $6.46
Step-by-step explanation:
Equations
The price per gallon of milk (m) and the price per gallon of orange juice (j) are given below:
m = 5.71 + 0.25n
j = 4.66 + 0.60n
Where n is the number of months after December 31, 2018.
It's required to find the value of n when both prices are equal:
4.66 + 0.60n = 5.71 + 0.25n
Subtracting 0.25n:
4.66 + 0.60n - 0.25n = 5.71
Subtracting 4.66:
0.60n - 0.25n = 5.71 - 4.66
Operating:
0.35n = 1.05
n = 1.05/0.35
n = 3
The price per gallon of milk for n=3:
m = 5.71 + 0.25*3
m = 5.71 + 0.75
m = $6.46

Mikayla downloaded 64
pictures from the cloud to her laptop.
These pictures took up 192 megabytes
of space on her laptop. Each picture
took up the same amount of space.
How many megabytes do 25
of these pictures take up?
Answer:
25 pictures will take up 75 Megabytes of space.
Step-by-step explanation:
Given that:
Number of pictures downloaded = 64
Space taken by pictures = 192 MBs
Unit rate = [tex]\frac{192}{64}[/tex]
Unit rate = 3 Megabytes per picture
Now,
The space 25 pictures would take,
25 pictures = 3*25
25 pictures = 75 Megabytes
Hence,
25 pictures will take up 75 Megabytes of space.

Need help FAST!!!! I need to find the value of x and y with work
Step-by-step explanation:
Step One: We need to find a way to equate either the x terms of the y terms in each equation. ...
Step Two: Take equation b) from equation a) to eliminate the x component. ...
Step Three: substitute the value of y into either equation to find the value of x.
Step-by-step explanation:
I think x equals 125. The reason is because a triangle is 180 and if you take 180 out of a 55 you will get a 125. The y will equal 55.

Which answer includes the intrevals that contain the solution to the inequality x^2-1/3x+9<0
Answer:
x<±1 and x< -3
Step-by-step explanation:
Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality
x^2-1/3x+9<0
x^2-1/3x+9 (3x+9)²<0* (3x+9)²
(x^2-1)(3x+9) < 0
x²-1 < 0 and 3x + 9 <0
x²-1 < 0
x²<1
x<±√1
x<±1
Also 3x + 9 <0
3x < -9
x < -9/3
x < -3
Hence the required values of x are x<±1 and x< -3

The current flow to a transformer's primary circuit measures 16 amps. The transsformer's secondary current measures 80 amps. What the transformer's turns ratio?
Answer:
1/5
Step-by-step explanation:
The transformer formula is as expressed as
Ns/Np= Ip/Is
Ns and Np are the number of turns in the secondary and primary coil respectively
is and Ip are the currents in the secondary and primary coil respectively
Given the following
Ip = 16A
Is = 80A
Substitute into the formula
Ns/Np = 16/80
Ns/Np = 1/5
Hence the transformer's turn ratio is 1/5
Answer: for pf, 1:5 is WRONG!
Step-by-step explanation:
Which is a possible turning point for the continuous function f(x)?
Answer:
We are given coordinates of a continuous function f(x)
(–2, 0)
(0, –2)
(2, –1)
(4, 0).
We need to find the possible turning point for the continuous function.
Note: Turning point is a point on the graph where slope of the curve changes from negative to positive or positive to negative.
A turning point is always lowest or highest point of the curve (where bump of the graph seen).
For the given coordinates we can see that (–2, 0) and (4, 0) coordinates are in a same line, that is on the x-axis.
But the coordinate (0, –2) is the lowest point on the graph.
Therefore, (0, –2) is the turning point for the continuous function given.

Answer:
A.) $0.89
Step-by-step explanation:
2(4x+3y=7.43)
-3(5x+2y=7.03)
8x+6y=14.86
-15x-6y=-21.09
add the two equations
-7x=-6.23
divide by -7
x=.89
Answer:$0.89
Step-by-step explanation:
Solution by substitution method
4n+3p=7.43
5n+2p=7.03
Suppose,
4n+3p=7.43→(1)
5n+2p=7.03→(2)
Taking equation (1), we have
4n+3p=7.43
⇒4n= -3p+7.43
⇒n = -3p+7.43/4
→(3)Putting n= -3p+7.43/4 in equation (2), we get
= 5n+2p=7.03
= 5(-3p+7.43/4)+2p=7.03
⇒-15p+37.15+8p=28.12
⇒-7p + 37.15=28.12
⇒-7p=28.12 - 37.15
⇒-7p=-9.03
⇒p=9.03/7
⇒p= 1.29→(4)
Now, Putting p=1.29 in equation (3), we get
n=-3p+7.43
n= -3(1.29)+7.43 / 4
⇒n= -3.87+7.43 / 4
⇒n= 3.56 / 4
⇒n=0.89
∴n= $0.89 and p=1.29

The extra data costs are $20.99 monthly but they're offering 20% off that. What will my monthly cost be with the 20% off?
Answer:
Discounted price= $16.792
Step-by-step explanation:
Giving the following information:
The extra data costs are $20.99 monthly, but they're offering 20% off that.
To calculate the discounted price, we need to use the following formula:
Discounted price= normal price*(1 - discount rate)

Discounted price= $16.792
In is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says that her commission is five and a half percent of the selling price. The salesperson will earn $27.23 by selling a couch for $495 to Lin and her dad.
Answer:
A. $27.23
B. $467.77
Step-by-step explanation:
Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5 1/2% of the selling price. A.How much commission will the salesperson earn by selling a couch for $495?
B.How much money will the store get from the sale of the couch?
Salesperson commission = 5 1/2%
Price of couch = $495
A. Amount earned by the salesperson = 5 1/2% of $495
= 5.5% × 495
= 0.055 × 495
= 27.225
Approximately
Amount earned by the salesperson = $27.23
B.How much money will the store get from the sale of the couch?
Amount the store get = Total price - amount earned by salesperson
= $495 - $27.23
= $467.77
Joel ordered a set of beads. He received 40 40 beads, and 60 % 60% of them were blue and 40 % 40% of them are green. How many blue beads did Joel receive?
Answer:
24 blue beads
Step-by-step explanation:
The number of blue beads is calculated as:
Percentage of blue beads × Total number of beads
Total number of beads = 40 beads
Hence:
= 60% × Total number of beads
= 60% × 40
= 60/100 × 40
= 24 blue beads
Joel received 24 blue beads.

[tex]\mathbf{\beta=140\ dB}[/tex]
Step-by-step explanation:
The Logarithm Function
The sound level is usually calculated as a logarithm by the formula:
[tex]\displaystyle \beta=10\log\frac{I}{I_o}[/tex]
Where
I = Sound intensity in W/square meter
Io = Smallest sound intensity that can be heard.
[tex]I_o=1\cdot 10^{-12}\ W/m^2[/tex]
The blue whale can emit a sound of I=106.8 W/square meter, thus the sound level is:

The octal numeral system is a base 8 positional system that uses the symbols 0,1,2,3,4,5,6,7. Write each base 8 number as a base 10 number. 12 and 117
Step-by-step explanation:
(12) in base 8
= (1 * 8¹ + 2 * 8⁰) in base 10
= (8 + 2) in base 10
= 10 in base 10.
(117) in base 8
= (1 * 8² + 1 * 8¹ + 7 * 8⁰) in base 10
= (64 + 8 + 7) in base 10
= 79 in base 10.
Using octal numeral system, 12₈ number as 10₁₀ and (117)₈ number as (79)₁₀.
What is octal numeral system?Octal numeral system has "a base of 8 and uses the number from 0 to 7".
According to the question,
a) (12)₈
= (1 * 8¹ + 2 * 8⁰)₁₀
= (8 + 2)₁₀
= 10₁₀.
b) (117)₈
= (1 * 8² + 1 * 8¹ + 7 * 8⁰)₁₀
= (64 + 8 + 7)₁₀
= (79)₁₀
Hence, using octal numeral system, 12₈ number as 10₁₀ and (117)₈ number as (79)₁₀.

Answer:
1. m<rsv is 42 degrees
2.
Step-by-step explanation:
1.
2. Since abc is 95, the two angles you have to solve are going to equal 95 when added because they make up the angle ABC so solving it would be like
(2x+23)+(9x-5)=95 you then solve this which would be
2x+23+9x-5 = 95 - Combine like terms
11x+18=95 Subtract 18 both sides
11x=77 divide by 11
x=7
After this you just put 7 in the equations instead of X and solve it

What is the GCF of 6 and 36
Answer:
It's 6.
Step-by-step explanation:
6- 1, 2, 3, 6
36- 1, 2, 3, 4, 6
The greatest common factor of 6 and 36 is 6
Given data ,
Let the first number be represented as p
where the value of p = 6
Let the second number be represented as q
where the value of q = 36
To find the greatest common factor (GCF) of 6 and 36, we need to determine the largest positive integer that can divide both numbers evenly.
To begin, we can list the factors of each number:
Factors of 6 : 1 , 2 , 3 , 6
Factors of 36 : 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 36
From the lists, we can see that both 6 and 36 share a common factor of 6. The GCF of 6 and 36 is therefore 6, as it is the largest number that can evenly divide both 6 and 36.
Hence , the greatest common factor is 6
