It takes 22 hours for a hosepipe with a flow of 12 litres per minute to fill a swimming pool. How long will it take if its flow
Monica [59]

Answer:

t2 = 52.8 hours

it will take 52.8 hours if its flow is reduced to 5 litres per minute.

Step-by-step explanation:

The volume of the swimming pool can be written as;

Volume V = flow rate × time

V = R×t

V = R1×t1 = R2×t2

R1×t1 = R2×t2

t2 = R1×t1/R2 ........1

Given;

Flow rate R1 = 12 litres per minute

Flow rate R2 = 5 litres per minute

time t1 = 22 hours

Substituting the given values into equation 1;

t2 = R1×t1/R2 = 12×22/5

t2 = 52.8 hours

it will take 52.8 hours if its flow is reduced to 5 litres per minute.

Write the perimeter of each figure as a trinomial. <br> Must show your work.
noname [10]

Answer:

P = 2n + 8m - 1

Step-by-step explanation:

A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.

If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.

The perimeter is the total length of all the sides.

The formula for the perimeter of a triangle is P = s_{1} + s_{2}  + s_{3} for each of the three sides.

Substitute each of the three sides.

P = s_{1} + s_{2}  + s_{3}

P = n + (2m + n)  + (6m - 1)

P = n + 2m + n  + 6m - 1 brackets can be removed

P = n + n + 2m + 6m - 1 rearrange equation according to like terms

P = 2n + 8m - 1 collected the like terms by addition
