Answer:
[tex]\mathbf{I = 0.22 \ amperes}[/tex]
Step-by-step explanation:
From above:
let assume that;
The current is [tex]\dfrac{1}{2}[/tex] ampere when resistance is 240 ohms.
Now, to find the current when R = 540 ohms.
SO; if [tex]I \ \alpha \ \dfrac{1}{R}[/tex]
[tex]I \ =\ \dfrac{k}{R}[/tex] where k = constant
[tex]\dfrac{1}{2} \ =\ \dfrac{k}{240}[/tex]
[tex]2k = 240[/tex]
[tex]k = \dfrac{240}{2}[/tex]
[tex]k = 120[/tex]
Thus; the constant = 120
So; when R = 540 ohms
then the current will be:
[tex]I = \dfrac{k}{R}[/tex]
[tex]I = \dfrac{120}{540}[/tex]
[tex]\mathbf{I = 0.22 \ amperes}[/tex]

Step-by-step explanation:
15x+y=25
solve for y
Answer:
y=25-15x (i hope it is right)
Answer: All you possible answer are y=25-15x, y=-15x+25, y=5(-3x+5), and -5(3x-5). Keep in mind that these answers all mean the same thing and have that same value but they are in different forms.
Step-by-step explanation:
To isolate the y, subtract 15x from both sides of the equation (in order to keep the equation balanced). You should get 15x+y-15x=25-15x. Simplify and your equation will be y=25-15x. It could also be rearranged to be y=-15x+25. If you want to go a step further, you can factor out 5 from -1x and 25 to get y=5(-3x+5). Finally, if you wanted to go even further, you could factor out -5 to get y=-5(3x-5). So all you possible answer are y=25-15x, y=-15x+25, y=5(-3x+5), and -5(3x-5). I don't really know which form you need it in. Hope this helps!
Kallie drank 12.75 gallons of water in 3 weeks. She drank the same amount of water each day. Estimate how many gallons she drank in one day.
Answer:
607 miltliters per day
Step-by-step explanation:
Step one:
given data
Kallie drank 12.75 gallons of water in 3 weeks
if she drank the same amount each day, then in one day she will drink
Note----there are 31 days in 3 weeks (7 days make 1 week)
Step two:
Hence in one day she will drink
= total volume of water/number of days
= 12.75/21
=0.607liters per day
or
607 militliters per day

what is 220% of 15? ............
Answer:
33
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer: 33
Step-by-step explanation: Write 220% as 220/100
Finding the fraction of a number is same as multiplying the fraction with the number 220/100 of 15
220/100 x 15
Therefore, the answer is 33
y + y
PLS HELP pls pls pls
Answer:
y=0
Step-by-step explanation:
Simplifying
y + y = 0
Combine like terms: y + y = 2y
2y = 0
Solving
2y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = 0
Simplifying
y = 0
Answer:
The correct answer is,
[tex]2y[/tex]

find the greatest common factor of the numbers 9 and 49
I'm pretty sure the answer is 1.
If x – 9 is a factor of x2 – 5x – 36, what is the other factor?
Answer: (x+4)(x−9)
Step-by-step explanation:
Answer:
(X - 9) is one factor
(X + 4) is the other factor
Step-by-step explanation:
You can factor polynomials with guess work or with polynomial division
To factor using guess work search for a number that will multiply with -9 to equal -36 and add with -9 to equal -5.
In order for -9 to add with another number and equal -5 you need to add 4 to it. And because -9 will multiply with 4 to equal -36 as well, 4 is confirmed to be the other factor. You can write out the factor as (x + 4)
There are 272 people in an audience. The ratio of adults to children is 5 : 3. How many are children? (please answer)
Answer:
There are 102 children
Step-by-step explanation:
Let us solve the question
∵ There are 272 people in an audience
∴ The total number of people = 272
∵ The ratio of adults to children is 5: 3
→ Find the sum of the two parts of the ratio
∴ The sum of the parts of the ratio = 5 + 3 = 8
→ By using the ratio method
→ Adults: Children: People
→ 5 : 3 : 8
→ A : C : 272
→ By using the cross multiplication
∵ C × 8 = 3 × 272
∴ 8C = 816
→ Divide both sides by 8
∴ C = 102
∵ C represents the number of children
∴ There are 102 children

Which ordered pair is a solution to the equation y = -6x?
(12, -2)
(3,-9)
-10.60)
(18, -3)
Answer:
(-10; 60)
Step-by-step explanation:
y = -6x
(12; -2)
-2 = -6 · 12
-2 = -72 - no
(3; -9)
-9 = -6 · 3
-9 = -18 - no
(-10; 60)
60 = -6 · (-10)
60 = 60 - yes
(18; -3)
-3 = -6 · 18
-3 = -78 - no

Answer:
y = 4/5x
y = 4/5x - 3.2
Step-by-step explanation:
The equation for slope is y=mx+b, the mx stands for the slope which is 4/5x. The b stands for where the line goes through the y axis, in this equation the first line crosses the y axis at the origin (0) and the second one crosses at -3.2, these are also called y-intercepts because they intercept the y axis.

Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some Sour Straws for $1.50 each. How many Sour Straws can Jamal purchase with the money that he has? Variable: ______________________________ Inequality: ______________________________ Solution: ______________________________
Answer: Variable: y= Number of sour straws.
Inequality: 7.50+1.50y ≤ 15
Solution: y ≤ 5
Step-by-step explanation:
Let y= Number of sour straws.
Cost for nachos = $7.50
Cost per sour straw = $1.50
Total cost = 7.50+1.50y
Money he has $15
Total cost must be less than orequal to the money he has.
So required inequality: 7.50+1.50y ≤ 15
Subtract 7.50 from both sides
[tex]1.5y\leq 7.5\\\\\Rightarrow\ y\leq\dfrac{7.5}{1.5}\\\\\Rightarrow\ y\leq 5[/tex]
He can buy at most 5 sour straws.

Is (2, 10) a solution to this system of equations?
y = 4x + 2
y = x + 8
Answer:
Yes, (2, 10) is a solution to this system:
y = 4x + 2
y = x + 8
Step-by-step explanation:
When graphed, the two equations cross at (2,10) making it a solution.
Answer:
Yes
Step-by-step explanation:
If y=4x+2 and y=x+8, then 4x+2=x+8
4x+2=x+8
4x=x+6
3x=6
x=2
Plugging this into the original equation "y=x+8", we obtain the result that y=10.
This means, (2, 10) is a solution to the system.
