A(1). The Equation to isolate I will be I = V / R.
B(2).If V=220 volts and R= 2 ohms, what is the value for I will be 110 amperes
C(3). The equation to isolate R will be R = V / I.
D(4).If V=550 and I=1.5 amperes, what is the value of R will be 366.66 Ohms.
What is Ohm's law?Ohms's law of electricity states that the current passing through the closed circuit is directly proportional to the voltage developed across the circuit.
Where R is the constant and called the resistance. The resistance is actually the restriction offered by the material in the flow of the charge or current.
The mathematical form of Ohm's law is given as:-
V=IR,
where V is voltage, I is current, and R represents the resistance.
A). The Equation to isolate I will be,
I = V / R.
B). If V=220 volts and R= 2 ohms, what is the value I will be
I = V / R
I = 220 / 2 =110 Volts.
C). The equation to isolate R will be,
R = V / I.
D). If V=550 and I=1.5 amperes, what is the value of R will be,
R = V / I
R = 550 / 1.5 = 366.66 Ohms.

After a 60% reduction, a jacket sold for $20. What was the jackets price before the reduction
Answer:
x-0,6x=20
0,4x=20/:0,4
x=50
Step-by-step explanation:
The original price of the jacket will be $50.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that after a 60% reduction, a jacket sold for $20. The original cost of the jacket will be calculated as below:-
Let the unknown number be x. Form the equation and solve for the value of x.
x-0,6x=20
0,4x=20/:0,4
x=50
Therefore, the original price of the jacket will be $50.

Erin and Aimee are each responsible for mowing half of their back yard. the yard is rectangular with dimensions 75 feet by 90 feet. Erin starts mowing the corner, gradually working her way towards the middle by mowing concentric bands around the outside edges. If the mower cuts a three foot wide path, at what point should Erin and Aimee stop mowing?
Answer:
Erin should stop at three and a half rounds.
Step-by-step explanation:
One complete round will mow 954 square feet, the total area that she has to mow 3375 square feet. If she goes around three and a half times, she should be finished and stop. This was quite hard to figure out, and may very well be incorrect in some way, but I hope this helps.

What is the solution to the inequality in interval notation? |4x+6|≤14
A: [-2,5] B: (-∞, −2] ∪ [5,∞) C: (-∞,-5] ∪ [2,∞) D: [-5,2]
Answer: x>5
Step-by-step explanation: The Absolute Value term is |4x+6|
For the Negative case, we'll use -(4x+6)
For the Positive case, we'll use (4x+6)
-(4x+6) = 14
Multiply
-4x-6 = 14
Rearrange and Add up
-4x = 20
Divide both sides by 4
-x = 5
Multiply both sides by (-1)
x = -5
Which is the solution for the Negative Case
(4x+6) = 14
Rearrange and Add up
4x = 8
Divide both sides by 4
x = 2
x=-5
x=2

Using the Distance Formula and the Pythagorean Theorem, find the distance, to the nearest tenth, from F (5,5) to G (−3,−1).
Answer:
The answer is 10 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
F (5,5) , G (−3,−1)
The distance between them is
[tex] |FG| = \sqrt{( {5 + 3})^{2} + ({5 + 1})^{2} } \\ = \sqrt{ {8}^{2} + {6}^{2} } \\ = \sqrt{64 + 36} \\ = \sqrt{100} \: \: \: \: \: \: \: \: \\ = 10 \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

Distance formula: d = √(x2-x1)²+(y2-y1)²
= √(x2-x1)²+(y2-y1)²
= √(-3-5)²+(-1-5)²
= √-8²+(-6)²
= √64+36

Step-by-step explanation:
1. There are 6 more water glasses than coffee mugs in a cabinet. There are 26 water glasses and coffee mugs in the cabinet, in all. How many coffee mugs are there in the cabinet? Write and solve an equation, where m represents the number of coffee mugs, to solve the problem. 2. The product of a number, x, and six is three less than seven times the difference of the same number, x, and four. Write an equation to represent this statement.
Answer:
10
Step-by-step explanation:
No of coffee mugs = m
No of water glasses = g
g = m + 6
g + m = 26
m + 6 + m = 26
m + m = 26 - 6
2m = 20
2m/2 = 20/2
m = 10

Add one term to the polynomial expression 14x^19 – 9x^15 + 11x^4 + 5x^2 + 3 to make it into a 22nd degree polynomial.
Answer:
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].
Step-by-step explanation:
A polynomial is a sum of algebraic monomials such that:
[tex]p = \Sigma_{i=0}^{n} c_{i}\cdot x^{i}[/tex]
Where [tex]n[/tex] is the degree of the polynomial and [tex]c_{i}[/tex] is the i-th coefficient of the polynomial. A 22nd degree polynomial has [tex]n = 22[/tex], so that given polynomial must added by a monomial with grade 22. Thus:
If [tex]p = 5\cdot x^{2} + 11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}[/tex] and [tex]q = 12\cdot x^{22}[/tex], then we have:
[tex]p' = p+q[/tex]
[tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex]
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].

What is the value of k for which the following equation has one solution?
|14+ 7x| - 15 = k
Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1

Answer:
sb= 44
Step-by-step explanation:
be is half of the line so 22 is half of the line
22×22=44
tell me if I'm correct if u can
hope this helps :)
Step-by-step explanation:
Hey there!
M is the midpoint of SB.
Midpoint seperates the line into 2 equal parts.
I.e SM = BM.
So, If BM = 22.
SB = 22+22= 44 [As SM = BM and SB= SM + BM]
Therefore the value of SB is 44.
