Joe borrowed $900 from Sam for six months. How much will Sam earn if he charges Joe a simple interest rate of 4 percent?

Answers

Answer 1

Answer:

Answer:

Sam would earn $18.00 from Joe.

Step-by-step explanation:

Joe borrowed $900 from Sam for six months. Sam charges simple interest at the rate of 4%.

In this question we have to find out Interest for 6 months with this formula.

I = Prt

I = Interest

P = Principal ( $900 )

r = rate of interest ( 4% ) in decimal

t = time in years. (1/2 yrs.)

first we convert 4% in decimal form.

4% = $(4)/(100)$ = 0.04

I = 900 × 0.04 × $(1)/(2)$

I = 36 × $(1)/(2)$

I = $18.00

Sam would earn $18.00 from Joe.

Answer 2

Answer: simple interest
you can charge it monthly or yearly

find 4% and multiply by how many months or years
4% of 900=
0.04 times 900=36
that is each time the interst is added

if it is monthly, (6months so ) 6 times 36=216
if it is yearly (6months=1/2year so )6 times 1/2=3

if it is taken monthly, then Sam earns $216
if it is taken yearly, then Sam earns $3

What is three -fifths of thirty

Answers

the answer is 18. 30 divided by 5 is 6. so 3 times 6 is 18.

what is three-fifths of thirty?
well we can look at this way easier by setting them both up with fractions
and since we don't know the numerator (the top number) for thirty we just put x in its place:)
3 x
----- -----
5 30

all we need to do is figure out what we multiplied by 5 to get 30
well lets just divide 30 by 5 ...
30 ÷ 5 = 6
so that means that we multiplied 6 to get 30
in order to get x we do the same to the top number of 3/5 so (3)
3 x 6 = 18 and thats what equals x!
so 3/5s of 30 is 18!
Answer = 18

Suppose the population of trout in a certain stretch of a river is 4000. In about how many years will the population of trout be 700 if the decay rate is 35%? Use the equation 700 = (4000)(0.65)x and round the value of x to the nearest year.

Answers

Answer: 4 years

Step-by-step explanation:

The exponential decay equation is given by :_

$y=A(1-r)^x$ , where A is the initial population and r is the rate of decay in x years .

The initial population of trout in a certain stretch of a river =4000

The rate of decay = 35% =0.35

To find the number of years (x) for the population of trout be 700, we put all the values of the above equation, we get

$700=4000(1-0.35)^x\n\n\Rightarrow700=4000(0.65)^x\n\n\Rightarrow (0.65)^x=(700)/(4000)\n\n\Rightarrow(0.65)^x=0.175\n\n\text{Taking log on both sides, we get}\n\n\Rightarrow x\log(0.65)=\log(0.175)\n\n\Rightarrow x(-0.187086643357)=-0.756961951314\n\n\Rightarrow x=(-0.756961951314)/(-0.187086643357)\n\n\Rightarrow\ x=4.0460502029\approx4\text{ years}$

4.97991230017 years is the final answer. I would suggest rounding your answer to the nearest tenth, so 5 years should be your correct answer.

Answer:

Inverse

Step-by-step explanation:

Assuming that c is a constant (the constant of proportion), s = c / (t^3) is a case of inverse variation: As t increases, s decreases.

Write the equation of a circle with a center at (0, 8) and a radius of 9.

Answers

Answer:

$x^2 + (y-8)^2= 81$

Step-by-step explanation:

the equation of a circle with a center at (0, 8) and a radius of 9.

To frame the equation of the circle we use center radius form of equation

$(x-h)^2 + (y-k)^2= r^2$

Where (h,k) is the center and 'r' is the radius

Given center is (0,8) and radius = 9

h = 0 , k= 8 and r= 9

Plug in all the values

$(x-h)^2 + (y-k)^2= r^2$

$(x-0)^2 + (y-8)^2= 9^2$

$x^2 + (y-8)^2= 81$

Find the probability of getting a doublet in a throw of a pair of dice.

Answers

There are six ways to roll 2 dice such that both dice have the same value
These are the outcomes (1,1),(2,2),(3,3),(4,4,)(5,5) and (6,6).

To find the total number of outcomes, note that there are 6 choices for the first die (values 1–6) and there are 6 choices for the second die (again values 1–6) and so by the Multiplication Principle (MP) there are 36 total outcomes from rolling two dice once.

Now we have the following:

P(getting a doublet) =
Total number of outcomes
Number of ways to get double

=
36
6

=

Thus, the probability of getting a doublet is

.

Question:

Find the probability of getting a doublet in a throw of a pair of dice.

Answer:

The probability is 1 out of 6.

Explanation:

There are a total of 6 possibilities that you get a doublet, which is {1, 1}, {2, 2}, {3, 3}, {4, 4}, {5, 5}, and {6, 6}.

The total possibilities of throwing a dice are 6 possibilities for the first dice, and 6 possibilities for the second dice. Which results in a total of 6 × 6 = 36 possibilities available.

Probability = Possibilities of getting doublet ÷ Total possibilities = 6 ÷ 36 = 1 ÷ 6.

Hopefully this answer will help you.
