What is a reasonable estimate for the sum of 4 1/8+3 2/3+5 1/2

A responsible estimate would be 14.
You estimate each of the mixed numbers to the nearest whole number:
4 1/8=4 because 1/8 is less than 1/2 so the number stays the same
3 2/3=4 because 2/3 is grater than 1/2
5 1/2 =6 because 1/2 is equal to 1/2 which means you estimate up.
So 4+4+6=14

First, mentally add the whole numbers.
4+3+5=12
Now, look at the fractions. 1/8, 2/3, and 1/2.
2/3 is bigger than 1/2, so you can add in another whole number.
12+1=13
1/8 is tiny, and won't add a whole lot to the mix, so just leave that.
A reasonable estimate would be 13 1/8

What is the maximum value of the objective function, P, with the given constraints?

maksim [4K]

Answer:

Option C - 420

Step-by-step explanation:

Given : Objective function, P, with the given constraints

$P=20x+35y$

Constraints,

$x+y \leq 12$

$5x+y \leq 20\\x \geq 0\\y \geq 0$

To find : What is the maximum value

Solution :

First we plot the graph through the given constrains.

As they all move towards the origin the common region of the equations is given by the points (0,0), (0,12), (2,10), (4,0)

Refer the attached figure.

So, we put all the points in P to, get maximum value.

$P=20x+35y$

Point (0,0)

$P=20(0)+35(0)=0$

$P=20x+35y$

Point (0,12)

$P=20(0)+35(12)=420$

Point (2,10)

$P=20(2)+35(10)=40+350=390$

Point (4,0)

$P=20(4)+35(0)=80$

Therefore, The value is maximum 420 at (0,12)

So, Option C is correct.

Since 1972 the US. inflation rate has averaged 4.8 % per year . Use the approximate doubling time formula to estimate the doubli

Artemon [7]

Answer:

14 3/4 years

Step-by-step explanation:

Let's assume compound inflation. The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t Find t, the time required for prices to double.

Then:

2 = 1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048) = 14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.

Given the graphs of f(x) = x – 1 and g(x) = –x – 7, what is the solution to the equation f(x) = g(x)?

Ghella [55]

Answer:

(-3, -4)

Step-by-step explanation:

f(x) = x – 1 and g(x) = –x – 7

f(x) = g(x)

x-1= -x-7
2x= -6
x= -3
f,g= -4
