Answer:

You need to add 12 pint of yellow.

Step-by-step explanation:

This is the method I used:

There is 4 pint of Yellow (Y) and 4 pint of Blue (B)

because they said is in equal amounts, so they are 50% each.

We need 80% Y and 20% B

so 4:20 = x=80   (4 pints is 20% as "how many pints" is 80%)

So x = 16

We already have 4 pint of Yellow, so we need more 12.

Suppose the wholesale price of a certain brand of medium-sized eggs p (in dollars/carton) is related to the weekly supply x (in
Mrrafil [7]

Answer:

1300

Step-by-step explanation:

We are given

x = 35

\frac{dp}{dt}=-0.05  [rate of change of price with time]

We want to find \frac{dx}{dt}, which is the rate at which supply is changing.

First, we need to implicitly differentiate the equation given:

625p^2-x^2=100\\1250p\frac{dp}{dt}-2x\frac{dx}{dt}=0

Here, we have what we need except for p. We find p when x = 35:

625p^2 - x^2 =100\\625p^2 - (35)^2 =100\\625p^2=1325\\p=1.46

Now, find dx/dt:

1250(1.46)(-0.05)-2(35)\frac{dx}{dt}=0\\-91.25-70\frac{dx}{dt}=0\\\frac{dx}{dt}=-1.30

In thousands, 1.30 * 1000 = 1300 cartons per week decrease

Answer:

 (10a+5)²= 100 a( a+1) + 25

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given

     (10a+5)²

By using (a+b)² = a² +2ab +b²

                   = (10a)²+ 2 × 10a× 5 + (5)²

                   = 100a² + 100a + 25

                   = 100 a( a+1) + 25
