One large box of birdseed can feed half a dozen parrots for 15 days. For how many days can this same large box of birdseed feed
iren [92.7K]
Box = b
Parrots = p
b/p = number of days it can support the parrots
Half a dozen = 6 (A dozen is 12)
1/6 = 15
To work out the percentage of '6' '5' is, use the equation
(5/6)*100 = 83.333....
Meaning that with one less bird, the box will support the birds for 16.666... (100 - 18.333...) longer
(15/100)*116.666... = 17.4999....
The box will sustain the parrots for 17.5 days

Employees of a landscaping company built a retaining wall. They used brick to make the top 2/3 of the wall. The wall is 8and 1/2
IgorC [24]

Answer:

Height of the brick portion of the wall is 5.61 feet.

Step-by-step explanation:

Employees of the landscaping company used brick to build the top 2/3 of the wall. The total dimensions of the wall are 8 and 1/2 * 2 and 3/4 feet. So the height of the wall = 8 and 1/2 feet or in other words 8.75 feet.

Height of the brick portion of the wall = 2/3 * 8.5 = 0.66 * 8.5 = 5.61 feet

So the height of the brick portion of the wall is 5.61 feet.

Non brick portion of the wall is 8.5 - 5.61 = 2.89

Which kind of decimals are irrational?
ella [17]

Answer:

D.) Those that never end and have no pattern

Definition:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
