GuDViN [60]

Answer:

At the end of the party 5.5 gallons or 88 cups of punch will be leftover.

Step-by-step explanation:

Given:

There are 20 guest at a party.

Now, to find the quantity of punch that will be leftover.

Number of guests = 20.

Total gallons of punch = 8.

Now, using conversion factor we change gallons into cups:

1 gallon = 16 cup.

So, 8 gallons = 16 × 8 = 128 cups.

Thus, total cups of punch = 128.

Total number of cups each guest will drink = 2.

Now, to get total number of cups the 20 guests will drink by multiplying:

$20\times 2$

$=40\ cups.$

Total number of cups the 20 guests will drink = 40.

So, to get the leftover punch we subtract the total number of cups the 20 guests will drink from total cups of punch:

$128-40\\\\=88\ cups.$

So, 88 cups = $88\div 16=5.5\ gallons.$

Therefore, at the end of the party 5.5 gallons or 88 cups of punch will be leftover.

Find UX and the area of △UVW.

Mkey [24]

Answer:

UX ≈ 4.5

△UVW = 49.5 ft²

Step-by-step explanation:

[] We can assume that UX is the midline of this triangle.

22 ft / 2 = 11 ft

XW and VX = 11 ft

[] Now that we have 2 sides of a right traingle, we can find the third.

a² + 11² = 12²

a² + 121 = 144

a² = 20

a = about 4.5, which is side UX

[] Since we have all three sides of the triangle, we can also solve for the total triangle's area. To solve for the area of a triangle, we do base times height divided by 2

22 * 4.5 = 99

99 / 2 = 49.5 ft²

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
