after 6 months, $1.78 simple interest was earned on an investment of $890. what was the annual interest rate

1 answer:

6 0

First you have to double the simple interest to get the amount earned in 1 year. That gives $3.56 earned and a total balance of $893.56
r = (1/t)(A/P - 1) t=time, A=amount of money with interest, P=amount invested
r = (1/1)((893.56/890) - 1) = 0.004
r = 0.004
now convert to a decimal to get .04 = 4%

You cut off half of a strip of paper. then you cut half of the piece was left. then you cut half of the remaining piece.

lianna [129]

Answer:

The fraction of the original strip left is $\frac{1}{8}$ .

Step-by-step explanation:

We have that,

A strip of paper is cut in $\frac{1}{2}$ . So, the strip of paper left is $\frac{1}{2}$ .

Now, again the remaining part is cut in half. The part left will be $\frac{1/2}{2}$ i.e. $\frac{1}{4}$ .

Finally, the remaining part is again cut in half.

We get, the final part of the paper remaining is $\frac{1/4}{2}$ i.e. $\frac{1}{8}$ .

So, the fraction of the original strip left is $\frac{1}{8}$ .

A student rides his bike to school with an average velocity of 10 miles per hour. It takes him 12 minutes to get to school. Writ

Dovator [93]

Answer:

The function is $d=10t$

domain is 0 to 0.2 hour.

range is 0 to 2 miles.

Step-by-step explanation:

Given that,

Average velocity = 10 miles/hour

Time = 12 min = 0.2 hour

We need to write a function that models the student's distance from home

Using formula of distance

$d=v\times t$

Where, v = velocity

t = time

d = distance

Put the value into the formula

$d=10t$

This is a function.

We know that,

Domain :

Domain shows the time.

So, domain = 0 to 0.2 hour

Range :

Range shows the distance.

The range at t =0,

Put the value of t in the function

$d = 10\times0=0$

The range at t =0.2 hour

$d = 10\times0=0$

$d=2\ miles$

So. range = 0 to 2 miles

Hence, The function is $d=10t$

domain is 0 to 0.2 hour

range is 0 to 2 miles

If a rectangle has a area of 36x^3+24x^2-18x and the width is 6x what is the length

diamong [38]

Answer:

$lenght= 6 {x}^{2} + 4x - 3$

Step-by-step explanation:

$lenght = \frac{area}{width} \\ \\ = \frac{36 {x}^{3} + 24 {x}^{2} - 18x }{6x} \\ \\ = \frac{6x(6 {x}^{2} + 4x - 3) }{6x} \\ \\ lenght= 6 {x}^{2} + 4x - 3$
