Answer:

4.4%

Step-by-step explanation:

solution:

principal (p) = $300

time(t) = 3 years

interest (I ) =$40

rate (r) = ?

we know that,

I = (PTR)/100*

OR, 40 = (300 *3 * R)/100

or, 40 = (900R)/100

or, 40 = 9R

or, 40/9 = R

or, R = 4.4%

Rate(r) =4.4%

Use the graph to write the explicit rule of the arithmetic sequence.

Igoryamba

Answer:

$f_n=7+\left(-2\right)\left(n-1\right)$

Therefore, option C is true.

Step-by-step explanation:

From the graph, we get the sequence

7, 5, 3, 1, ...

Here,

a₁ = 7 is the first element.

An arithmetic sequence has a constant difference 'd' and is defined by

$f_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$5-7=-2,\:\quad \:3-5=-2,\:\quad \:1-3=-2$

The difference between all the adjacent terms is the same and equal to

$d=-2$

substituting a₁ = 7 and d = -2 in the nth term of the sequence

$f_n=a_1+\left(n-1\right)d$

$f_n=7+\left(-2\right)\left(n-1\right)$

Therefore, option C is true.

A company is expanding its building area from 17,000 square feet to 22,610 square feet. What is the percentage increase of the a

Luden [163]

Answer:

The percentage increase of the area of the building space is 33%.

Step-by-step explanation:

We are given the following in the question:

Original area of company = 17,000 square feet

Expanded area of company = 22,610 square feet

We have to calculate the percentage increase of the area of the building space.

Increase percentage =

$=\dfrac{\text{Increase}}{\text{Original}}\times 100\%$

Putting values, we get,

$=\dfrac{22610-17000}{17000}\times 100\%\\\\=\dfrac{5610}{17000}\times 100\%\\\\=33\%$

Thus, the percentage increase of the area of the building space is 33%.
