a city has a population of 370000 people. suppose that each year the population grows by 4,5%. what will the population be after

sashaice [31]

Population=370000

Population growth=4.5%

Increase in Pop growth in a year=

( {100+4,5}/100 )×370000= 386,650 people

Therefore growth in 15years=

386650×15 =

5,413,100 people

In ΔABC, a = 660 cm, b = 680 cm and c=100 cm. Find the measure of ∠B to the nearest degree.

scoundrel [369]

Answer:

m∠B = $97^{o}$ .

Step-by-step explanation:

Since the three sides of the triangle are given, then we apply cosine rule.

$b^{2}$ = $a^{2}$ + $c^{2}$ - 2ac Cos B

But, a = 660 cm, b = 680 cm, and c = 100 cm.

So that;

$680^{2}$ = $660^{2}$ + $100^{2}$ -2(660 x 100) Cos B

462400 = 435600 + 10000 - 132000 Cos B

462400 = 445600 - 132000 Cos B

132000 Cos B = 445600 - 462400

= -16800

Cos B = $\frac{-16800}{132000}$

= -0.1273

B = $Cos^{-1}$ -0.1273

= $97^{o}$

Thus, measure of ∠B is $97^{o}$ .

Dory lives 2.5 miles from school. Jim lives 3.2 kilometers from school. Ely lives 2300 meters from school, and Chris lives 3000

dezoksy [38]

Answer: $Ely, Chris, Jim, Dory$

Step-by-step explanation:

The distances must be expressed in the same uni.

Let's express the distance in meters.

We know that Dory lives 2.5 miles from school.

Since:

$1\ mi = 1.61\ km$

The distance in kilometers is:

$(2.5\ mi)(\frac{1.61\ km}{1\ mi})=4.025\ km$

Since $1\ km = 1,000\ m$

The distance in meters is:

$(4.025\ km)(\frac{1,000\ m}{1\ km})=4,025\ m$

Jim lives 3.2 kilometers from school. The distance in meters is:

$(3.2\ km)(\frac{1,000\ m}{1\ km})=3,200\ m$

Chris lives 3,000 yards from school.

Since:

$1\ m = 1.09\ yd$

The distance in meters is:

$(3,000\ yd)(\frac{1\ m}{1.09\ yd})=2,752.29\ m$

Therefore, the order of the students from closest to farthest from school is:

$Ely, Chris, Jim, Dory$
