Answer:

a) 0

b) 4.5

c) 3

d) 6

Step-by-step explanation:

Formula: 3x + 4y = 12

The questions contains the values of x. So here's an example of:

d) x = -4, y = ?

Using the formula: 3(-4) + 4y = 12

-12 + 4y = 12

4y = 24

y = 6

Do the same for the others!

If 3t-7=5t, then 6t= Whyyyy? I need help with being explained why it's -21....

Alex17521 [72]

Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.

You said that 3t - 7 = 5t

OK. Fine.
Let's just find out what 6t is.

Subtract 3t from each side: -7 = 2t

Multiply each side by 3 : -21 = 6t

Did I go too fast for you ?

How long will it take for an investment to triple, if interest is compounded continuously at 8%?

maw [93]

Answer:

It will take 14 years before the investment triples

Step-by-step explanation:

Continuous Compounding

Is the mathematical limit that compound interest can reach if it was calculated and reinvested into an account's balance over a theoretically infinite number of periods.

The formula for continuous compounding is derived from the formula for the future value of a compound interest investment:

$FV = PV\cdot e^{i.t}$

Where:

FV = Future value of the investment

PV = Present value of the investment

i = Interest rate

t = Time

It's required to find the time for an investment to triple, that is, FV = 3 PV, knowing the interest rate is i=8%=0.08.

Substituting the known values:

$3PV = PV\cdot e^{i.t}$

Dividing by PV:

$3 = e^{i.t}$

Taking logarithms:

$\ln 3=i.t$

Solving for t:

$\displaystyle t=\frac{\ln 3}{i}$

$\displaystyle t=\frac{\ln 3}{0.08}$

t = 13.7 years

Rounding up:

It will take 14 years before the investment triples

What is 1/10 of 200

gladu [14]

1/10x200
= 1/10x200/1
= 200/10
=20

the answer is 20

if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200

200/10=n
n= 20
