Answer:

900

Step-by-step explanation:

perimeter: P = 2w + 2h

P = 2(20) + 2(25)

P = 40 + 50

P = 90

Multiply perimeter by 10:

90 × 10 = 900

What is the length of segment AB

Lady bird [3.3K]

Answer: $\large \boldsymbol {C) \ AB=\sqrt{41} }$

Step-by-step explanation:

The formula for the distance between points:

$\bf AB= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
Coordinates of point A (0;5 ); coordinates of point B(4;0)
$\bf AB= \sqrt{(0-4)^2+(5-0)^2} =\sqrt{16+25} =\sqrt{41}$

Althea’s family decided to attend the yearly sailing festival in their town. This year the boat races will include both rowing a

MariettaO [177]

Answer:

(a)

$Area= 27ft^2$ --- the catboat

$Area = 25ft$ --- the sloop

(b)

$Cost = \$40.5$ -- the catboat

$Cost = \$37.5$ --- the sloop

Step-by-step explanation:

Incomplete question (See attachment)

For the catboat, we have:

$Base = 9ft\\Height = 6ft$

For the Sloop, we have:

$Base = 7 + 3 = 10ft$

$Height = 5ft$

Solving (a): The area of both sailboats.

Since both are triangular, we use:

$Area= 0.5 * Base * Height$

For the catboat

$Area= 0.5 * 9ft*6ft$

$Area= 27ft^2$

For the sloop

$Area = 0.5 * 10ft * 5ft$

$Area = 25ft$

<em>The catboat has the greater sail area because 27 > 25</em>

Solving (b): Cost of sail for each.

We have the unit price to be:

$Unit = \$1.50/ft^2$

So, the cost is calculated by multiplying the unit price by the total area.

So, we have:

For the catboat;

$Cost = 27ft^2 * \$1.50/ft^2$

$Cost = \$40.5$

For the sloop

$Cost = 25ft^2 * \$1.50/ft^2$

$Cost = \$37.5$
