What is the Compound interest on a 10,000 investment the earns 6% compound monthlyfor5 years
Answer:
The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest
Step-by-step explanation:
So the formula for this would be:
A = P(1+r/n)^nt
A = the amount of your principal plus interest, which is the total
P = stands for the principal, which is your original amount invested
r = shows the interest rate in decimal form
n = stands for the number of compounding periods
So to solve for the compound interest we would plug in our numbers in replacement for the letters

suppose a varies directly as b, and a =8 when b =3 find b when a =24
Answer:
b=9
Step-by-step explanation:
since a varies directly as b,
a=kb
k=a/b
k=8/3
but when a=24, b will be given by
b=a÷k
b=24÷8/3, b=24×3/8
b=9

Amy is training for a half marathon. in practice, she runs 2 miles in 15 minutes. If she continues at the same rate, how many miles will she run in 1 hour?
A. 4
B. 8
C. 16
D. 30
Step-by-step explanation:
B. 8
she will run for 8 miles,
stepfind Amy's speed
convert the minutes into hours by dividing by 60
[tex] \frac{2}{15 \times \frac{1}{60} } \\ = 8 \: miles \: per \: hour[/tex]
find the number of miles ran by multiplying the speed by the time, ie
[tex]8 \times 1 = 8 \\ \: therefore \: the \: answer \: is \: \: 8 \: miles[/tex]
6. What is the value of x in the solution to the systems of linear equations shown below?
2x - 2y+z=3
5y-z= -31
x+ 3y + 2z = -21
Step-by-step explanation:
[tex]1) \: \: 2x - 2y + z = 3 \\ 2x = 3 + 2y - z \\ x = \frac{3 + 2y - z}{2} \\ \\ 2) \: \: \: not \: any \: \: \: x \: \: \: available \: \: \\ \\ 3) \: \: x + 3y + 2z = - 21 \\ x = - 21 - 3y - 2z[/tex]
Answer:
x= -5
Step-by-step explanation:
5y-z= -31, add z and 31 to both sides
5y+31 = z, substitute z in the other two given equations
2x - 2y+z=3
2x-2y +5y+31 = 3, combine like terms and subtract 31 from both sides
2x+3y = -28
x+ 3y + 2z = -21
x+3y +2(5y+31) = -21, distribute 2 over the addition parenthesis
x+3y +10y+62 = -21, combine like terms and subtract 62 from both sides
x+13y = -83
Now we have 2 equations with 2 variables x and y to solve
2x+3y = -28
x+13y = -83
Because we need to find x then from the first equation we can write that
3y = -2x-28, subtract 2x from both sides and the divide both sides by 3
y = (-2x-28)/3, substitute this in the second equation
x + [13(-2x-28)/3] = -83 , distribute 13 . over the subtraction parenthesis
(3x/3)+[(-26x - 364) /3= -83, find the common denominator
3x+[(-26x - 364) = -83*3 , cross multiply
3x -26x = -249 +364, add 364 to both sides
- 23x = 115, divide both sides by (-23)
x= -5

Can anyone help me its due tomorrow
Answer:
No,the price is not within their budget.
Step-by-step explanation:
Because if you take 144 times 76 you get 10,944 which goes past their budget of 10,000
Answer:
They are over budget by $1,232.
Step-by-step explanation:
They want to replace 144 computer monitors each for $76.
$76 * 144 = $11,232
Their budget is $10,000 so they would be over budget by:
$11,232 - $10,000 = $1,232

Three friends participated in a "Biggest Loser" weight loss competition. The table below shows their starting weight and the weight after two months:
Starting Weight
Weight After Two Months
Jacob
225 pounds
207 pounds
Timothy
200 pounds
188 pounds
Hamza
280 pounds
259 pounds
Who lost the biggest percentage of his starting weight?
You need to find the percentage of weight loss for each participant.
To find the percentage of weight loss use the formula
Starting weight – Weight after two months x 100
Starting Weight
Answer:
Jacob lost the biggest percentage of his starting weight.
Jacob: 8%
Timothy: 6.4%
Hamza: 7.5%
Formula: (initial weight - new weight)/initial weight times 100.
Step-by-step explanation:
Jacob: 225 pounds - 207 pounds = 12 pounds
x/100 = 12/225
= 1800/225
= 8%
Timothy: 200 pounds - 188 pounds = 12 pounds
x/100 = 12/188
= 1200/188
= 6.4%
Hamza: 280 pounds - 259 pounds = 21 pounds
x/100 = 21/280
= 2100/280
= 7.5%

• But at maximum volume, dv/dx is 20 square inches.
[tex]{ \rm{ - 4 {x}^{2} - 160x + 400 =2 0}} \\ \\ { \rm{ {x}^{2} + 40x - 95 = 0}}[/tex]

Solve for w.
–1.01 = 1.4(w + 2) − 2.41
w=0
Step-by-step explanation:
-1.01=1.4(w+2)-2.41
-1.01=1.4w+2.8-2.41
-1.01=1.4w+0.39
-1.01-0.39=1.4w
+1.4=1.4w
1.4/1.4=w
0=w
So,the answer is w=O

what is the domain of f in the equation f(x)=2(x-1)^2-4
Answer:
[tex](-\infty, \infty)[/tex]
Step-by-step explanation:
There are no restrictions on the possible values of [tex]x[/tex], because you can square any number.
Because [tex]x[/tex] can be anything, the domain is all reals or [tex]\boxed{(-\infty, \infty)}[/tex] which means [tex]x[/tex] can be any real number.
