We are planning a reception for our daughter. The hall that we are renting charges $55 clean up fee. In addition to the cleanup

elena55 [62]

Answer:

89 is the maximum number of guests that can be invited within budget .

Step-by-step explanation:

The cleaning charges = $55

Total budget available = $3350

Cost per guest = $37

Now, actual budget available for guest = Total budget - Cleaning Fee

= $3350 - $ 55 = $3,295

Now, cost per head =$ 37

So, number of guests (n) possible in the budget

⇒ n = (Total guest Budget)/ Cost per head

= $3,295 / $37 = $89.05

or, n = $89.05

So, 89 is the maximum number of guests that can be invited within budget .

The average weight of the class of 35 students was 45 KG. with the admission of a new student the average weight came down to 44

melamori03 [73]

The weight of the new student is 27 kg.

Average weight

= total weight ÷total number of students

<h3>1) Define variables</h3>

Let the total weight of the 35 students be y kg and the weight of the new student be x kg.

<h3>2) Find the total weight of the 35 students</h3>

y= 35(45)

y= 1575 kg

<h3>3) Write an expression for average weight of students after the addition of the new student</h3>

New total number of students

= 35 +1

= 36

Total weight

= total weight of 35 students +weight of new students

= y +x

$44.5 = \frac{y + x}{36}$

<h3>4) Substitute the value of y</h3>

$44.5 = \frac{1575 + x}{36}$

<h3>5) Solve for x</h3>

36(44.5)= 1575 +x

1602= x +1575

<em>Subtract 1575 from both sides:</em>

x= 1602 -1575

x= 27

Thus, the weight of the new student is 27 kg.

find the y value for the point that splits segment GH in half of point G is located at (-3,5) and point H is located at (0,-2)

olganol [36]

Y=1.5 at the midpoint of GH. To do this you add the y values of the endpoints together and divide by two ----> 5-2= 3 ----> 3/2= 1.5

Hope this helps you !!
