Find g<br>Write your answer in simplest radical form

a_sh-v [17]

Answer:

g = 7 yards

Step-by-step explanation:

you have 7 $\sqrt{3}$ yards for the angle adjacent 30 deg.

tan 60 = $\sqrt{3}$

tan 60 = 7 $\sqrt{3}$ / g

7 * root(3) / g = root(3)

7/g = 1

g = 7 yards

José is blocking off several rooms in a hotel for guest coming to his wedding. The hotel can reserve small rooms that can hold 3

miv72 [106K]

Answer:

$x=2y\,,\,3x+4y=70$ where x denotes number of small rooms and y denotes number of large rooms

Step-by-step explanation:

Given: Small rooms can hold 3 people, and large rooms can hold 4 people.

Number of small rooms is twice the number of large rooms.

Small rooms and large rooms altogether can accommodate 70 guests.

To find: system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved

Solution:

Let x denotes number of small rooms and y denotes number of large rooms.

As number of small rooms is twice the number of large rooms,

$x=2y$

As small rooms and large rooms altogether can accommodate 70 guests such that small rooms can hold 3 people, and large rooms can hold 4 people,

$3x+4y=70$
