What is 7 2/5 - 3 3/8

enyata [817]

Answer:

161/40

Step-by-step explanation:

$(7+ \frac{2}{5} ) - (3+ \frac{3}{8})$

$\frac{35+2}{5} - \frac{24+3}{8}$

$\frac{37}{5} - \frac{27}{8}$

$\frac{296-135}{40} = \frac{161}{40}$

In 2018, the population will grow over 700,000.The population of a city in 2010 was 450,000 and was growing at a rate of 5% per

Firlakuza [10]

Answer:

The year is 2020.

Step-by-step explanation:

Let the number of years passed since 2010 to reach population more than 7000000 be 'x'.

Given:

Initial population is, $P_0=450,000$

Growth rate is, $r=5\%=0.05$

Final population is, $P=700,000$

A population growth is an exponential growth and is modeled by the following function:

$P=P_0(1+r)^x$

Taking log on both sides, we get:

$\log(P)=\log(P_0(1+r)^x)\\\log P=\log P_0+x\log (1+r)\\x\log (1+r)=\log P-\log P_0\\x\log(1+r)=\log(\frac{P}{P_0})\\x=\frac{\log(\frac{P}{P_0})}{\log(1+r)}$

Plug in all the given values and solve for 'x'.

$x=\frac{\log(\frac{700,000}{450,000})}{\log(1+0.05)}\\x=\frac{0.192}{0.021}=9.13\approx 10$

So, for $x > 9.13$ , the population is over 700,000. Therefore, from the tenth year after 2010, the population will be over 700,000.

Therefore, the tenth year after 2010 is 2020.

Applying the geometric mean(Leg) theorem what is the value of q?

Darya [45]

Answer:

2√14

Step-by-step explanation:

x+y/a = a/y

10+4/s = s/4

14/s = s/4<em> you cross multiply and get </em>

a²=56

√a = √56

a = 2√14
