When signing the lease for her $825.00 per month rental property, Selah will have to pay the first month's rent, last month's rent, and a
security deposit equal to 25% of one month's rent. If Selah currently earns an average weekly net pay of $650.00, determine what percent
of her weekly pay she will need to save ishe wants to sign her lease in 8 weeks.
O a
2.8%
Ob 3.6%
OC 28%
Od 35.7%
Selah needs to save 35.7% of her weekly pay she will need to save if she wants to sign her lease in 8 weeks.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Starting from the bottom in 8 weeks Selah will earn $(8×650).
= $5200.
The cost of renting the property for 2 months is $(2×825).
= $1650.
And 25% of one month's rent as a security deposit is,
= (25/100)×825.
= $206.25.
So, The total amount she needs to sign is $(1650 + 206.25).
= $1856.25.
Therefore, The percentage of her weekly pay she will need to save is,
= (1856.25/5200)×100.
= 35.69% or 35.7%

Use differentials to estimate the amount of metal in a closed cylindrical can that is 22 cm high and 10 cm in diameter if the metal in the top and the bottom is 0.4 cm thick and the metal in the sides is 0.05 cm thick. (Round your answer to two decimal places.) cm3
Answer:
97.43cm³
Step-by-step explanation:
h = 22cm
d = 10cm
r = d/2
= 10/2
= 5
dh = 2(0.4)
= 0.8
dr = 0.05
V = πr²h
dV = d(πr²h)
Such that
πd(r²h)
= π[(r²dh + hd(r²)]
dV = π[(r²dh + 2rhdr]------(1)
When we put the values above in this equation 1 above:
dV = π[(5)²*0.8 + 2*5*22*0.05]
= π(25*0.8+11)
= π31cm³
Multiply the value of pi with 31cm³
= 97.43cm³
Approximately how many years will it take $3000 to double if it is invested in an account that pays 3%
compounded monthly? Round your answer to the nearest whole year.
Answer:
24 years
Step-by-step explanation:
Total = start*(1 + interest rate / amount of times compounded per month)^(years*amount of compounds per year)
6000 = 3000*(1+0.03/4)^(4x)
6000 = 3000* ((403/400)^4)^x
2 = ((403/400)^4)^x
x = log base-((403/400)^4) of 2 = x
x = 23.19
rounding down 23 years (but you probably want a year over that to get at least 6000, so 24)

The distance between the points where the points are given as (2.4, -5.4) and (9.2-5.4) is 6.8 units
How to determine the distance between the points?The points are given as
(2.4, -5.4) and (9.2, -5.4)
The distance between the points is calculated as
d = √(x2 - x1)^2 + (y2 - y1)^2
Substitute the known values in the above equation
So, we have
d = √(9.2 - 2.4)^2 + (-5.4 + 5.4)^2
Evaluate the sum in the above equation
So, we have
d = √(9.2 - 2.4)^2 + (0)^2
Evaluate the difference in the above equation
So, we have
d = √(6.8)^2 + (0)^2
Evaluate the exponents in the above equation
So, we have
d = √46.24 + 0
Evaluate the sum in the above equation
So, we have
d = √46.24
Evaluate the exponents in the above equation
So, we have
d = 6.8

What are the roots of f(x)=x^3-x^2-5x-3?
Answer:
x=3 and x=-1
Step-by-step explanation:
Given Descartes' Rule of Signs, there is only one positive root and one negative root.
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient.
So P could be +1, -1, +3, or -3, while Q could be 1 or -1.
Therefore, P/Q could be +1, -1, +3, or -3.
Then we use synthetic division to find the correct factor(s):
1 | 1 -1 -5 -3
___ 1_0_ -5
1 0 -5 | -8
So (x-1) is not a factor
-1 | 1 -1 -5 -3
___-1_2_ 3
1 -2 -3 | 0
So (x+1) is a factor where the quotient is x^2-2x-3 or (x-3)(x+1)
3 | 1 -1 -5 -3
___ 3_6_ 3
1 2 1 | 0
So (x-3) is a factor where the quotient is x^2+2x+1 or (x+1)^2
Given (x-3) and (x+1) are factors, we now use the Zero Product Property:
(x-3)(x+1)=0
x-3=0
x=3
x+1=0
x=-1
So the roots are x=3 and x=-1

Step-by-step explanation:
In the figure below, the distance from A to D is y, the distance from D to C is x and the distance from A to B is h.
Using trigonometric ratios we calculate the value of the variables as approximately x and y are 5.1 units and 3.1 units respectively .
Trigonometry is the branch of mathematics that is used for solving a right angled triangle if only one data is given.
Let us consider a triangle ABC right angled at B. BC is the base of the triangle and AC is the hypotenuse , therefore AB is the perpendicular.
The various trigonometric ratios used for solving a triangle are :
sin C = AB ÷ AC
cos C = BC ÷ AC
tan C = AB ÷ BC
Now in the given figure we can see that :
In ΔABC , using the trigonometric ratio of sin
sin ∠A = BC ÷ AB
or , sin 51° × AB = BC
or, BC = 10.102...
or, BC ≈ 10.1
Again in Δ BCD , using the trigonometric ratio of cos
cos ∠D = CD ÷ BD
or, CD ≈ 5.1
In ΔABC , using the trigonometric ratio of tan
tan ∠A = BC ÷ AC
or, tan 51° = 10.1 ÷ AC
or, AC = 8.178...
or, AC ≈ 8.2
Therefore the value of y is AC-DC = 8.2 - 5.1 = 3.1 units
The values of x and y are 5.1 units and 3.1 units respectively .

Paula knows the total cost for 100 students will be $750, and the cost total cost for 150 students is $1050. What is the caterer’s fixed cost and the rate per student served?
Step-by-step explanation:
the price charged for 100 students reflects the cost per student that applies to the order as a whole.
100 * 6 = $600, so the fixed cost is 750-600 = 150.
...
We can check this by substituting in the other equation.
Does 150*6 + 150 = 1050?
150*6=900
900+150 = 1050.
Yes, it does
...
We can express this relationship by the equation:
y = mx + b
where
y = total cost
m = $6 per student
x = number of students
b = fixed costs = 150
y = 6x + 150
The caterer’s fixed cost and the rate per student served is $6 and $150
How to choose what quantity to multiply the first equation?This method is actually called method of elimination to solve a system of linear equations.
We make one specific variable's coefficients of equal magnitude so that we can subtract or add the equations and eliminate that variable to make it easy to get the value of the other variable which will then help in getting the value of the first variable (if working in dual variable system).
If we have equations:
[tex]a_1x + b_1y = c_1\\a_2x + b_2y = c_2[/tex]
then, if we want to eliminate variable x, then we have to multiply equation 1 with
[tex]-\dfrac{a_2}{a_1}[/tex]
which will make coefficient of x in first equation as
[tex]a_1 \times - \dfrac{a_2}{a_1} = -a_1[/tex]
Then adding both equation will eliminate the variable x.
Given;
Cost of 100 students= $750
Cost of 150 students= %1050
Let the fixed cost of caterer be x
and the cost per student be y
x+100y=750...(1)
x+150y=1050...(2)
solving the above equations;
50y=300
y=6
x=750-600=150
The fixed cost is $150, while the per-student cost is $6.

What is the slope of the line that passes through the points (-9,5) and (-17,5)? Write your answer in simplest form.
Answer:
0
Step-by-step explanation:
Without solving anything, we can tell that the line that crosses these points is a horizontal line because both of the y-coordinates are the same. This tells us that the slope of the line is 0.
To prove this, we can find the slope of the line by plugging the two points,[tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], into the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]\frac{y_2-y_1}{x_2-x_1}\\\frac{5-5}{-17-(-9)}\\= \frac{0}{-17+9)}\\= \frac{0}{-8}\\= 0[/tex]
Therefore, the slope of the line that passes through the points (-9,5) and (-17,5) is 0.
