Find the perimeter of a rectangle with a base of 24m<br> and a height of 36m.

bogdanovich [222]

To find the perimeter of a rectangle, you need to add the lengths of the rectangles four sides. Since we have the base and the height this is easy. 24 x 2 + 36 x 2 = 120. Hope this helps!

Answer:

$a_7=-15$

Step-by-step explanation:

$a_n$ is given as the nth term of a sequence.

We want to find $a_7$ , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for $a_n$ to find the value of the 7th term of the sequence.

We show this below:

$a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15$

So the 7th term is "-15"

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 7500(1 + (0.06 × 6)) = 10200

A = $10,200.00

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for th

GarryVolchara [31]

Answer:

The function would be linear because the rate of change is constant.

Step-by-step explanation:

Given

$Base= \$89.00$

$Rate = \$0.10$ per minute

See attachment for complete question and options

First, we write the function that calculates the cost (C(t)) for t minutes.

This is calculated as:

$Cost = Base + Rate * t$

$C(t) = 89.00 + 0.10 * t$

$C(t) = 89.00 + 0.10t$

Rewrite as:

$C(t) = 0.10t + 89.00$

A function that has the above format is referred to as a linear function which has the general format

$f(x) = mx + b$

Where

m represents the slope/rate and it is constant

From the list of given options, (a) is correct.
