Answer: 2 days

Step-by-step explanation:

The monkeys eat 3 ²/₃ buckets of bananas each day. Convert this to an improper fraction:

= 3²/₃ = 11/3 buckets per day

The zookeeper bought 7¹/₃ which is:

= 22/3 buckets

To find out the number of days the bananas will last, divide the buckets bought by the buckets eaten per day:

= 22/3 ÷ 11/3

= 22/3 * 3/11

= 66/33

= 2 days

<em>If dividing fractions, multiply by the reciprocal of the second fraction. </em>

on a piece of paper graph y=(x+2)(x-3) then determine which answer choice best matches the graph you drew. Provide an explanatio
ioda

Answer:

option C

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • y = (x + 2)( x -3)

And we need to tell which graph best matches the graph we drew. Firstly let's convert it into a quadratic equation by opening and simplifying the brackets.

:\implies y = ( x + 2) ( x - 3)

:\implies y = x ( x - 3)+2( x - 3)

:\implies y = x² - 3x + 2x -6

:\implies y = x² - x - 6

Now plot its graph. For that refer to attachment.

<u>Things </u><u>we </u><u>can</u><u> </u><u>interpret</u><u> </u><u>:</u><u>-</u><u> </u>

  • The constant in the equation is -6. So the graph will cut y axis 6 units below the X axis . At (-6,0)
  • From the given options , option C matches the above point .

<u>Therefore</u><u> the</u><u> </u><u>correct</u><u> </u><u>option</u><u> </u><u>is </u><u>(</u><u>C)</u><u> </u><u>.</u>

In what proportion should water and milk be mixed to reduce the price of milk from Rs 5 per liter to Rs 4 per liter?​
Wewaii [24]

Answer:

4:1

Step-by-step explanation:

Let us assume that the cost of water is free, that is Rs.0.

Let x represent the number of liters of milk, y represent the number of liters of water and z represent the volume of the mixture in liters, hence:

z = x + y            (1)

Milk cost Rs.5 per liter, water cost Rs.0 per liter and the mixture cost Rs.4 per liter. Therefore:

5x + 0(y) = 4z    (2)

Substituting z = x + y in equation 2 gives:

5x + 0(y) = 4(x + y)

5x = 4x + 4y

5x - 4x = 4y

x = 4y

x / y = 4 / 1

x : y = 4 : 1

The proportion in which the milk is to be mixed with water is 4 : 1, that is 4 liters of milk per 1 liter of water
