You bought a car for $25,000. You have owned it for one year, and it is now worth $21,000. What is the percent decrease in your car's value?16%19%84%119%

Answers

$25 000 - 100%
$21 000 - x %
25000x=21000 * 100
x=84%

100%-84%=16%

$\$25,000-\$21,000=\$4,000\n(\$4,000)/(\$25,000)\cdot100\%=16\%$
Answer: In your car's value the percent decrease is 16%.

A species of dolphins is decreasing at a rate of 3.1% per year.if there are currently 20000 dolphins , many will there be in 30 years

Answers

Answer:

7892 dolphins

Step-by-step explanation:

let P denote the dolphin population.

-Notice this is an exponential decay and is denoted as:

$P_t=P_oe^(-rt)$

Where;

$P_t$ is the population at time t
t is the time
r is the rate of decay or decrease in population
$P_o$ is the initial population size.

#Given t=30yrs, $P_o$ =20000 and r=3.1%, the population after 30 years is estimated as:

$P_t=P_oe^(-rt)\n\n=20000e^(-0.031* 30)\n\n=7891.07\approx7892\ dolphins$

Hence, the dolphin population after 30yrs is approximately 7892

The floor of a hall has an area of 48 dm.The floor is to be tiled by triangular tiles.of sides 20 cm,30 cm and 40 cm. Find the total cost of tiles if cost of each tile is Rs.200.

Answers

The triangle is an obtuse triangle. No sides are equal.
convert cm to dm

1 dm = 10 cm

side a: 20 cm ⇒ 20cm * 1dm/10cm = 20dm/10 = 2 dm
side b: 30 cm ⇒ 30cm * 1dm/10cm = 30dm/10 = 3 dm
side c: 40 cm ⇒ 40cm * 1dm/10cm = 40dm/10 = 4 dm

We need to get the area of a triangle, but first we need to solve for its height using Heron's formula

s = (a+b+c)/2 = (2+3+4)/2 = 9/2 = 4.5
Area = √(s(s-a)(s-b)(s-c)
h3/2 = √4.5(4.5-2)(4.5-3)(4.5-4)
h3/2 = √4.5(2.5)(1.5)(0.5)
h3/2 = √8.44
h3/2 = 2.91
h = (2.91*2)/3
h = 1.94

A = hb/2 = (1.94*3)/2 = 5.82/2 = 2.91 dm²

48 dm² / 2.91dm² = 16.5 or 17 tiles needed

17 x Rs200 = Rs3,400 is the total cost

You don't need anybody else to give you the answer.
It's really easy to do it yourself.

A fraction is a short way of writing a division problem.
Every fraction means

(the top number) divided by (the bottom number) .

When you pick up your pencil or your calculator and actually do
the division, the answer you get is the decimal form of the fraction.

To find the decimal form of 3/16, just divide 3 by 16 .
