Answer:

The given expanded sum of the series is \sum\limits_{n=5}^{9}3n+2=115

Step-by-step explanation:

Given problem can be written as

\sum\limits_{n=5}^{9}3n+2

To find their sums:

Now expanding the series

That is put n=5,6,7,8,9 in the given summation

\sum\limits_{n=5}^{9}3n+2=[3(5)+2]+[3(6)+2]+[3(7)+2]+[3(8)+2]+[3(9)+2]

=[15+2]+[18+2]+[21+2]+[24+2]+[27+2]

=17+20+23+26+29  (adding the terms)

=115

Therefore \sum\limits_{n=5}^{9}3n+2=115

Therefore the given sum of the series is \sum\limits_{n=5}^{9}3n+2=115

The given expanded sum of the series is \sum\limits_{n=5}^{9}3n+2=115

A house is valued at $118,000.00. The homeowner decides to add on a two-car garage that increased the value of the home by 15%.H
nasty-shy [4]

Answer:

The value of the house after adding the garage is $135,700.

Step-by-step explanation:

Given,

value of house before adding garage = $118,200.00

we need to find the value of house after adding two car garage.

Solution,

Since after adding two car garage the value of the house increased by 15%.

So firstly we will find out the 15% of the value of the house after adding garage.

So we can say that;

15% of the value of the house after adding garage is equal to 15 divided by 100 the multiplied with the value of the house before adding garage.

15% of the value of the house after adding garage = \frac{15}{100}\times118,000=\$17,700

Now, The value of the house after adding garage is equal to the sum of value of house before adding garage and 15% of value of house before adding garage.

We can frame it in equation form as;

The value of the house after adding garage = \$118,000+\$17,000=\$135,700

Hence The value of the house after adding the garage is $135,700.

Which of these choices is the best estimate for the answer of 3 1/4 + (-2 2/3)?
Evgesh-ka [11]
3 1/4 = 3.25
-2 2/3 = -2.6667
3.25 + (- 2.6667)
= 3.25 - 2.6667
= ~0.58
therefore best estimate is 0
