What’s this answer to this problem
Alisiya [41]

Answer

Area: 3,818

Perimeter: 258

Type: Rectangle

Solution

To find the Area you have to do

Length x Width

so it is 83 times 46 which is 3818

To find Perimeter it is

Length + Length + Width + Width

or 83 + 83 + 46 + 46 = 258

For type i don’t know so probably the type is rectangle

A hose is filling a water tank at the rate of 70 gallons per minute. A loose drain plug causes 8 gallons per minute to drain out
Alinara [238K]
62x=y
1860/62=30min

70 gallIons per minute, minus the 8 gallons per minute would give you a growth of 62 gallons per minute. you need 1860 gallons in total so divid that by your growth in which it'll take 30 minutes to fill up a 1860 gallon tank.
