Answer: The missing side is 24 inches

Step-by-step explanation:

Since it is a right angle that means that we can use the Pythagorean Theorem formula to solve for the B.

The formula says that a^2 + b^2 = c^2 Since we know a is 18 and c is 30 we will input the value into the formula to solve for b.

18^2 + b^2 = 30^2

324 + b^2 = 900

-324 -324

b^2 = 576

b = $\sqrt{576}$

b = 24

X^2 -15x +54 = 0 for you can factor it easy just you need getting two numbers with sum equal -15 and product equal 54

-15= (-9)+(-6) and (-9)*(-6)= -54 in this way will get

x^2 -15x +54 = (x-6)(x-9)

Un barco que hace cruceros por el mar Caribe dispone de camarotes de una plaza y de dos plazas. Si en total hay 215 camarotes y

prisoha [69]

Answer:

- There are 71 one-quarter cabins and 144 two-seater cabins on the cruise ship.

- Hay 71 cabinas de un asiento y 144 cabinas de dos asientos en el crucero.

Step-by-step explanation:

English Translation

A ship that cruises in the Caribbean Sea has one and two-seater cabins. If there are 215 cabins and 359 seats in total, find out how many cabins there are of each type.

Let the number of one seater cabins be x

Let the number of two seater cabins be y

There are x seats on the one seater cabins and there are 2y seats in total for the two seater cabins

x + y = 215 (eqn 1)

x + 2y = 359 (eqn 2)

Subtract eqn 1 from eqn 2

y = 359 - 215 = 144

x + y = 215

x = 215 - y = 215 - 144 = 71

There are 71 one-quarter cabins and 144 two-seater cabins on the cruise ship.

In Spanish/En español

Deje que el número de cabinas de un asiento sea x

Deje que el número de cabinas de dos plazas sea y

Hay x asientos en las cabinas de un asiento y hay 2 asientos en total para las cabinas de dos asientos

x + y = 215 (ecuación 1)

x + 2y = 359 (ecuación 2)

Resta la ecuación 1 de la ecuación

2 y = 359 - 215 = 144

x + y = 215

x = 215 - y = 215 - 144 = 71

Hay 71 cabinas de un asiento y 144 cabinas de dos asientos en el crucero.

Hope this Helps!!!

An advertisement reads all books 28 percent off a best-selling novel is originally priced at $18.99. About how much money will G

o-na [289]

28% of 18.99 is 5.2172

Because 18.99 * 0.28 = 5.2172 which can be rounded to 5.22

So Gio would save about $5.22.

What is the missing side length?<br> (Use Pythagorean Theorem)

Vedmedyk [2.9K]

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

$a^{2} + b^{2} = c^{2} \\$

Now we can insert values into the equation.

$a = 15\\b = b\\c = 25\\$

Now we can plug these ☝ values into the Pythagorean Theorem:

$15^{2} + b^{2} = 25^{2}\\$

After we solve for $b$ we get:

$b^{2} = 400\\b = 20$
