Answer:
Electricity bill is 175
Step-by-step explanation:
Given
[tex]Rent = 1800[/tex]
[tex]Gas = 150[/tex]
[tex]Each\ Roommate = 425[/tex] monthly
[tex]Number\ of\ Roommate = 5[/tex]
Required
Determine the electricity bill
If each roommate pays 425, then 5 roommates pay 5 * 425
[tex]Total = 5 * 425[/tex]
[tex]Total = 2125[/tex]
This implies that: the monthly cost of room, gas and electricity add up to 2125.
In other words,
[tex]Gas + Rent + Electricity = 2125[/tex]
[tex]150 + 1800+ Electricity = 2125[/tex]
[tex]1950+ Electricity = 2125[/tex]
[tex]Electricity = 2125 - 1950[/tex]
[tex]Electricity = 175[/tex]
Hence, the electricity bill is 175

Regional erosion occurs at a rate of 2 m per 1,000 years.
How much regional erosion will occur over 1,000,000 years?
A) 20 m
B) 200 m
C) 2,000 m
D) 100,000 m
Answer:
200
Step-by-step explanation:
It's 200 because you would take the 1,000 and multiply it by the power of 3, which is 100,000. So therefore you would do the same thing with the 2, which 2 to the power of 3 is 200. There is your explanation.

What is the axis of symmetry for the following equation?
y=4x2-8x+9
Answer:x=1
Step-by-step explanation:
The x of the top of the parabola is:
x=-(-8)/(2*4)=1
x=1
Using quadratic function concepts, it is found that the axis of symmetry for the function is x = 1.
The standard quadratic function is modeled by:
[tex]y = ax^2 + bx + c[/tex]
And has axis of symmetry given by:
[tex]x = -\frac{b}{2a}[/tex]
In this problem, the function is:
[tex]y = 4x^2 - 8x + 9[/tex]
The coefficients are:
[tex]a = 4, b = -8, c = 9[/tex]
Then, the axis of symmetry is:
[tex]x = -\frac{b}{2a} = -\frac{(-8)}(2(4)} = 1[/tex]

Answer:
[tex]\sqrt{(n-m)(n+m)}[/tex] & [tex]-\sqrt{(n-m)(n+m)}[/tex]
Step-by-step explanation:
1) Subtract [tex]m^{2}[/tex] from both sides. This should leave you with [tex]x^{2}=n^{2}-m^{2}[/tex].
2) Square root both sides. This should leave you with [tex]x=\sqrt{n^2-m^2}[/tex] & [tex]x=-\sqrt{n^2-m^2}[/tex].
You can stop here if this is what the problem is asking for. However, it is not fully simplified.
3) Factor the equation. This should leave you with [tex]\sqrt{(n-m)(n+m)}[/tex] & [tex]-\sqrt{(n-m)(n+m)}[/tex].
[tex]\boxed{\left \{ {{\sqrt{(n-m)(m+n)}} \atop {-\sqrt{(n-m)(m+n)}}} \right.}[/tex]
Solution Steps:- Steps using the quadratic formula -______________________________
1.) Subtract n² from both sides:[tex]n^2-n^2=0[/tex][tex]m^2-n^2=m^2-n^2[/tex]2.) Rewrite:This equation is in standard form: ax² + bx² + c = 0. Substitute 1 for a, 0 for b, and (m-n) (m+n) for c in the quadratic formula, [tex]\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}[/tex]:
[tex]x^2+m^2-n^2=0[/tex]2.a) Turns into:
[tex]x=\frac{0\frac{+}{}\sqrt{0^2-4(m-n)(m+n)}}{2}[/tex]3.) Square 0:[tex]0^2=0[/tex] (Also means it Cancels out.)4.) Take the square root of −4(m−n)(m+n):This just means combine them by squaring.
[tex]-4^2=2[/tex] (Half it, don't square it.)[tex](m-n)(m+n)^2=(n^2-m^2)[/tex]4a.) Our equation should look like this now:

using completing the square method in quadratic equation 5x²+ 11x + 2=0
Answer:
x= 1/5 or -2
Step-by-step explanation:
5x² +11x +2= 0
(Divide through by the coefficient of x²)
5x²/5 + 11x/5 + 2/5 = 0/5
x² + 11x/5 + 2/5 = 0
(take the constant to the other side)
x² + 11x/5 = -2/5
(Add 1/2 of the coefficisint of x all square to both sides)
x² + x + (11/5 × 1/2)² = -2/5 + (11/5 × 1/2)²
x² + x + (11/10)² = -2/5 + (11/10)²
x² + x + (11/10)² = -2/5 + 121/100
(eliminate x )
x² + (11/10)² = (20(-2) + 121 ) ÷ 100
(x + 11/10 )² = (-40 + 121) ÷ 100
(x + 11/10 )² = 81/100
(square both sides)
x + 11/ 10 =√(81/100)
x + 11/10 = 9/10
x = -11/10 +or- 9/10
x = -11/10 + 9/10 or -11/10 - 9/10
x = (-11 + 9) ÷ 10 or (-11-9) ÷ 10
x = -2/ 10 or -20/10
x = -1/5 or -2
A gallon of water weighs 8.34 pounds. The Rhoads family has a round, 12-foot diameter, above-ground pool. How much weight is added to the pool when it is filled with 3, 205 gallons of water?
Answer:
The amount of weight added is 26,729.7 pounds
Step-by-step explanation:
Here, we are told that a gallon of water weighs 8.34 pounds
Now, we want to find the weight of 3,205 gallons of water
Mathematically, that would be;
3,205 * 8.34 = 26,729.7 pounds
Find the value of (3x) in the figure
To find the missing angle, we need to find x.
[tex]3x + 2x - 10 = 180\\\\5x - 10 = 180\\\\5x = 190\\\\x = 38[/tex]
Now, we plug in what we got for x into 3x.
[tex]3(38)\\\\114[/tex]
The value of 3x is 114.

Isolate the variable by dividing each side by factors that don't contain the variable. im prob to late but i need points
The value of x in the equation is 4.
What is an algebraic expression?An Algebraic expression shows the expression of variables with numbers. The purpose of an algebraic expression is to determine the unknown variable represented by an unknown letter.
From the given information:
2(6x + 4) - 6 + 2x = 3(4x + 3) + 1
Open brackets
12x + 8 - 6 + 2x = 12x + 9 + 1
Collect like terms
12x + 2x - 12x = -8 + 6+9 + 1
14x - 12x = -8 + 16
2x = 8
x = 8/2
x = 4

M-5=49 please answer I need help
Answer:
M=54
Step-by-step explanation:
If you are trying to find the value of M, you add 5 to both sides
M-5+5=49+5
this way the M is all by itself on the left side of the equal sign because -5+5=0
when we combine the like terms we get
M+0=54
therefore M=54
Also 54-5=49
Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three point
Complete question :
Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?
Answer:
0.405224
Step-by-step explanation:
Given that:
p(success) = p = 74% = 0.74
If given 3 free throws ; probability of making all 3
Using binomial fórmula :
p = 0.74 ;
1 - p = 0.26
P( x = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 3) = 3C3 * 0.74^3 * 0.26^0
P(x = 3) = 1 * 0.405224 * 1
P(x = 3) = 0.405224
