Paha777 [63]

Answer: $84\ \text{units}$

Step-by-step explanation:

Given

The length of each cube is $a=14\ \text{units}$

If there are 6 cubes placed over each other, then the height achieved by the cubes is

$\Rightarrow 6\times 14\\\Rightarrow 84\ \text{units}$

Angelo and Deborah are landscapers. Angelo charges a one time fee of $50 plus $15 per hour. Deborah charges a one time fee of $2

Tems11 [23]

Answer:

5 hours

Step-by-step explanation:

Step one:'

given data

Angelo charges a one time fee of $50 plus $15 per hour

let the total charge be y

and the number of hours be x

y= 50+15x----------------1

Deborah charges a one time fee of $25 plus $20 per hour

y= 25+20x----------------2

equate 1 and 2 to find x

50+15x=25+20x

collect like terms

50-25= 20x-15x

25= 5x

divide both sides by 5

x= 25/5

x= 5 hours

Find the area of the regular polygon.<br>Round to the nearest tenth.<br>16 ft

Sladkaya [172]

<u>Given</u>:

Given that the side of the regular polygon is 16 feet.

We need to determine the area of the polygon.

<u>Area of the polygon:</u>

The area of the polygon can be determined using the formula,

$Area =\frac{s^2 n}{4 \ tan \frac{180}{n}}$

where n is the number of sides,

s is the side length.

Substituting n = 3 and s = 16, we get;

$Area =\frac{16^2 (3)}{4 \ tan \frac{180}{3}}$

Simplifying, we get;

$Area =\frac{(256) (3)}{4 \ tan \ 60}$

$Area = \frac{768}{6.928}$

Dividing, we get;

$Area = 110.85$

Rounding off to the nearest tenth, we have;

$Area = 110.9$

Thus, the area of the regular polygon is 110.9 square units.
