You deposit $3000 into an account that pays 4.8% interest, compounded monthly. A) What is the value of the account after 5 years?B) How long will it take for the value of the account to reach $6000?
Answer:
14.4 years (about 14 years 6 months)
Step-by-step explanation:
Given data
Principal= $3000
Rate= 4.8%
A. Time= 5 years
The expression for compound interest is
A=P(1+r)^t
Substitute
A= 3000(1+0.048)^5
A= 3000(1.048)^5
A=3000*1.264
A=$3792
Hence the balance will be $3792
B. Final Amount A = $6000
The expression to find time is given ast
t= ln(A/P) / r
substitute
t= ln(6000/3000)/0.048
t= ln2/0.048
t= 0.6931/0.048
t=14.43
Hence the time is 14.4 years (about 14 years 6 months)approx

how to solve 9x-5-(-6x)
Answer: 3x-5
Step-by-step explanation:
9x-5(-6x)
9x-5-6x
3x-5
Answer:
15x - 5
Step-by-step explanation:
We have the equation 9x - 5 - (-6x) and are asked to solve it.
We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :
9x - 5 - (-6x)
Two negatives make a positive, therefore :
9x - 5 + 6x
Since 9x and 6x have the same variable ending, we can combine them, do as followed :
9x - 5 + 6x
9x + 6x
15x - 5
A map show a town with an area of 3.5 inches.If the map has a scale of 1 inch:4 miles,what is the actual area of the town?
Answer:
The actual area of the town is 14 miles.
Step-by-step explanation:
Since you know that the scale is 1 inch:4 miles and that the map shows a town with an area of 3.5 inches, you can expressed this as follows:
Scale: 1 inch:4 miles
map area: 3.5 inches
If the actual area is x, you can say that:
3.5:x=1:4
This would be:
[tex]\frac{3.5}{x}=\frac{1}{4}[/tex]
Now, you can solve for x:
x=(3.5*4)/1
x=14
According to this, the answer is that the actual area of the town is 14 miles.

2/3 - 3/2y + 1/3y + 4 = 0
Answer:
y = 4
Step-by-step explanation:
(2/3 + 4) + (-3/2y + 1/3y) = 0
(-3/2y + 1/3y) = -4 2/3
-9/6y + 2/6y = -14/3
-7/6y = -14/3
cross-multiply:
-21y = -84
y = 4
Answer:
y = 4
Step-by-step explanation:
Please use parentheses for clarity, remembering what big differences they make in expression values.
I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0" actually means
2/3 - (3/2)y + (1/3)y + 4 = 0
The LCD here is 6, which is the product of the denominators 2 and 3.
Then your "2/3 - 3/2y + 1/3y + 4 = 0" becomes:
4 - 9y + 2y + 24 = 0, which simplifies to:
28 - 7y = 0. Solving this, we get y = 4
Jack's gross weekly pay is $498. He has $52 withheld from each paycheck for federal income
tax. In addition, Social Security, Medicare, state tax of 2.5 percent, and local tax of 1.25
percent are withheld from his paycheck. How much is withheld in Social Security, Medicare,
State, and Local taxes? Finally, what is his net pay?
Answer:
A. 56.78 B. 389.22
Step-by-step explanation:
A.Social security: 498x.062=30.88
medicare: 498x.0145=7.22
state tax: 498x.025=12.45
local tax: 498x.0125=6.23
total of above = 56.78
B. Total taxes above (56.78) + federal withheld (52) = total taxes 108.78
total pay 498 - total taxes 108.78 = 389.22

If the interest of a sum of money in 6years is 3 by 8 of the principal what is the rate of interest
Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25

Mount McKinley, in Alaska, is about 3.848 miles high. If a mountain climber can climb 0.25 miles per day, about how long to the nearest day, would it take to climb Mount McKinley?
Answer:
About 16 days.
Step-by-step explanation:
The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

The base of a triangle is 5 units greater than the height, if its area is 18cm2, what is the quadratic equation that models the situation described and is used to find the height of the triangle?
base= 5+h
height= h
area= 1/2bh, so since our area us 18cm^2
therefore 18=1/2*b*h
18*2=(5+h)*h
36=5h+h^2
h^2+5h-36=0 ( for quadratic equation)
h^2+9h-4h-36=0
(h^2+9h)(-4h-36)=0
h(h+9)-4(h+9)=0
(h-4)(h+9)=0
h=4 or h= -9
