Simple interest:

i = prt

where i = interest earned

p = principal deposited

r = annual rate

t = number of years

You want the interest to be $500. The rate is 4%, and the principal is $2000.

Enter those values in the formula for simple interest above and solve for t, the time in years.

500 = 2000 * 4% * t

500 = 2000 * 0.04 * t

500 = 80t

t = 6.25

Answer: 6.25 years

The number of views on an interesting video after it's uploaded is represented by the following table:

defon

Answer:

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is $,V(t)=50(6.25)^t$

Step-by-step explanation:

Time (months) Views

0 50

2 313

4 1950

6 12,210

8 76,300

10 476,800

$(x_1,y_1)=(0,50)\\(x_2,y_2)=(2,313)\\(x_3,y_3)=(4,1950)$

$Slope = \frac{y_2-y_1}{x_2-x_1}$

$Slope = \frac{313-50}{2-0}$

Slope =131.5

$Slope = \frac{y_3-y_2}{x_3-x_2}$

$Slope = \frac{1950-313}{4-2}$

Slope =818.5

Since the slope is not same . So, it is not a linear relationship

$\frac{y_2}{y_1}=\frac{313}{50}=6.25\\\frac{y_3}{y_2}=\frac{1950}{313}=6.25$

Since the ratio between the consecutive outputs is same so, it is exponential relationship.

Formula : $y=ab^t$

Where a is the initial value = 50

b = rate of change = 6.25

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data

So $,V(t)=50(6.25)^t$

Tomorrow Noelle wants to travel a total of 4 miles by walking and running she plans to run for 20 minutes at a rate of 6 miles p

elixir [45]

Answer:

Noelle will need to walk at a rate of 3 miles per hour for 2/3 of an hour to finish traveling the 4 miles.

Step-by-step explanation:

This will be a two part problem.

Noelle wants to travel 4 miles in total.

If she wants to run for 20 minutes at a rate of 6 miles/hour, we need to convert 20 minutes into terms of hours

20 minutes * 1 hour/60 minutes = 1/3 of an hour

let's find the distance she has traveled by running then using

d = r*t

where d is our distance in miles,

r is our speed in miles/hour, and

t is the time taken in hours

if r = 6 miles/hour and

t = 1/3 hours

we have

d = (6 miles/hour) * (1/3 hours)

hours will cancel out, leaving us with

d = 2 miles

If Noelle has covered 2 miles by running, how many minutes then will she need to walk at a rate of 3 miles per hour to cover the remaining two miles?

d = 2 miles

r = 3 miles/hour

2 miles = (3 miles/hour) *t divide both sides by 3 miles/hour

miles will cancel out, leaving us with

2/3 hours = t

Therefore, Noelle will need to walk at a rate of 3 miles per hour for 2/3 of an hour to finish traveling the 4 miles.

In an office,2/3 of the telephone bill is paid by Tom,1/5 paid by Azuma and the remaining by Tina. What fraction is paid by Tina

Marizza181 [45]

Answer:

4/15

Step-by-step explanation:

1 - 2/3 = 1/3

1/5 x 1/3 = 1/15 of the bill

1/15 of bill is paid by azuma

10/15 is by tom

so 1 - 10/15 - 1/15 = 4/15 by tina
