For this case we have the following expression:

$\frac {2} {5} m- \frac {4} {5} - \frac {3} {5} m =$

We add similar terms:

$\frac {2} {5} m- \frac {3} {5} m- \frac {4} {5} =$

Different signs are subtracted and the sign of the major is placed:

$\frac {2-3} {5} m- \frac {4} {5} =\\- \frac {1} {5} m- \frac {4} {5} =$

The expression is simplified as:

$\frac {-m-4} {5}$

ANswer:

$\frac {-m-4} {5}$

Answer:

1.5 or 3/2

Step-by-step explanation:

V = l x w x h

4 1/3 = 3/4 x 4 x L

3/4x4 = 3

3L = 4 1/2

Divide by 3

Length = 1.5 or 3/2

Answer:

You would have $343.37 at the end of the 2 years.

Step-by-step explanation:

Interest earned is like bonus money the bank pays you just for keeping money

$\mathrm{Compund\:Interest\:Formula}:\quad A = P { \left( 1+ \dfrac{ r }{ n } \right) }^{ nt }$

P: the starting balance of the account (also called initial deposit, or principal)

A: the new balance in the account after N years.

t: the number of years or time

r: the interest rate, (in decimal form)

n: the number of times the interest is compounded each year.

Annually = each year = 1

P =$300, r = 7%, t = 2, n = 1, A = ?

Substitute the numbers into the "Compound Interest Formula".

$A = 300 { \left( 1+ \dfrac{ 0.07 }{ 1 } \right) }^{ 1 \times 2 }$

$\mathrm{Anything\:divided\:by\:1\:gives\:itself}$

$A = 300 { \left( 1+0.07 \right) }^{ 1 \times 2 }$

$\mathrm{Add\:1\:and\:0.07\:to\:get\:1.07}$

$A = 300 \times { 1.07 }^{ 1 \times 2 }$

$\mathrm{Multiply\:1\:and\:2\:to\:get\:2}$

$A = 300 \times { 1.07 }^{ 2 }$

$\mathrm{Calculate\:1.07\:to\:the\:power\:of\:2\:and\:get\:1.1449}$

$A = 300 \times 1.1449$

$\mathrm{Multiply\:300\:and\:1.1449\:to\:get\:343.47}$

$A = 343.47$

So you would have $343.37 at the end of the 2 years.

Look at the chart

$\mathrm{Year}\quad \mathrm{Year\: Interest}\quad \mathrm{Total\:Interest}\quad \mathrm{Balance}\\\quad1\quad\quad\quad $21.00\quad\quad\quad\quad $21.00\quad\quad\quad\quad $321.00\\\quad2\quad\quad\quad $22.47\quad\quad\quad\quad $43.47\quad\quad\quad\quad $343.47$

Answer:

367.6 m

Step-by-step explanation:

Use trigonometry

Let the height of the cloud be x, then we have:

tan 35° = x/525
x = 525 tan 35°
x = 367.6 (rounded)

The height of the cloud layer is 367.6 m
