During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea
Liono4ka [1.6K]

Answer:

30 gallons

Step-by-step explanation:

step 1 right it out

2 hour is 120 mins and 4 cups are poured per min

step 2 Equation time

so your equation should be

4/1=x/120

step 3 solve it out

1 times 120 is 120 is 4 times 120 is 480

but that is not the answer 480 is the amount of CUPS that are used for 2 hrs

so all u have to do is now convert

step 4 convert

16 cups are in 1 gal. so divide 480 by 16 and get 30 gal

x=30 gallons

hoped it helped

Find the perimeter of the following.​
-Dominant- [34]

Answer:

24.997 = 25.00 (rounded off to 2 decimal figures)

Step-by-step explanation:

By observation, we can see that both straight lines are of equal length and that the angle between the lines is 90°. Hence we can conclude that this is a quadrant of a circle with radius, r =  7 cm.

length of the curved section

= 1/4 x circumference of the circle

= 1/4 x 2πr

= 1/4 x 2 x 3.142 x 7

= 10.997 cm²

HEnce circumference = 10.997 + 7 + 7 = 24.997 = 25.00 (rounded off to 2 decimal figures)
