Answer:

84°
125°

Step-by-step explanation:

<u>Sum of the interior angles of a regular polygon:</u>

S(n) = 180°(n - 2), where n- number of sides

<h3>Exercise 4</h3>

<u>Pentagon has sum of angles:</u>

S(5) = 180°(5 - 2) = 540°

<u>Sum the given angles and find x:</u>

x° + 122° + 100° + 90° + 144° = 540°
x° + 456° = 540°
x° = 540° - 456°
x° = 84°

<h3>Exercise 5</h3>

<u>Hexagon has sum of angles:</u>

S(6) = 180°(6 - 2) = 720°

<u>Sum the given angles and find x:</u>

x° + 110° + 160° + 105° + 105° + 115° = 720°
x° + 595° = 720°
x° = 720° - 595°
x° = 125°

Use grouping symbols and at least one exponent to write a numerical expression that has a value of 80.

Kaylis [27]

To group an expression, means that the factors of the expression are to be separated in (), [] or {}.

An expression with a value of 80 is: $2^2 \times ( [2 + 2] \times [3 + 2] )$

The number is given as:

$80$

Factorize

$80 = 2 \times 40$

Factorize 40

$80 = 2 \times 2 \times 20$

Express $2 \times 2$ as an exponent

$80 = 2^2 \times 20$

Express 20 as 4 x 5

$80 = 2^2 \times ( 4 \times 5)$

Express 5 as 3 + 2

$80 = 2^2 \times ( 4 \times [3 + 2] )$

Express 4 as 2 + 2

$80 = 2^2 \times ( [2 + 2] \times [3 + 2] )$

Hence, the above expression has a numerical value of 80

You have 55,000 in your savings account that pays 2.5% annual interest and the inflation rate is 3.4%. How much buying power wil

diamong [38]

We solve the question as follows:
Simple interest=Principle×Rate×Time
Thus given:
p=$55000, R=2.5%, time= 1 year
thus
Interest=55000×0.025×1=$1375

To evaluate the amount required to keep up with the inflation, your interest rate should match the inflation rate otherwise prices are going up faster than the savings.
Required interest rate=55000×0.034×1=$1870

The buying power lost will be the difference between your required interest and actual interest.

Thus:
Buying power lost=1870-1375=$495
