Which is the best estimate for the sum of 3/8 and 1/12¿

1 answer:

4 0

Estimating is an educated guess, so 3/8 is just less than half, and 1/12 is just a bit more than 0. So you could estimate that 3/8 + 1/12 = roughly 1/2

 if you add 3/8 and 1/12 you get 11/24

A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the numb

Ugo [173]

To answer this item, we take the differential of the equation and equate to zero.

C(x) = 0.8x² - 256x + 25939

Differentiation,
dC(x) = 1.6x - 256
dC(x) = 1.6x - 256 = 0

The value of x from the derived equation above is 160.

Thus, the number of machine to be made in order to minimize the cost should be 160.

Convert 5 square root of a into exponential form?

stich3 [128]

Answer:

The answer is: " $5a^\frac{1}{2}$ " .

_____________________________________________

Step-by-step explanation:

______________________________________________

We are asked to convert "5 square root of a" ; into "exponential form".

Note that "5 square root of a" ;

or; " 5 root a " ;

means: " 5 times the {square root of the variable, "a" };

or : " 5 multiplied by the {square root of the variable, "a" }.

_______________________________________________

This can be written as: " $5\sqrt{a}$ " .

_______________________________________________

Note the following property of exponents:

$\sqrt[n]{a^m} = (\sqrt[n]{a})^m = a^m^n$ .

_____________________________________________

So; to write: " √a " ; as an exponent :

______________________________________________

Note:

" $\sqrt{a} = \sqrt[2]{a} = \sqrt[2]{a^1} = (\sqrt[2]{a})^1 = a^\frac{1}{2}$ " .

_______________________________________________

So:

" $\sqrt{a} = a^\frac{1}{2}$ " ;

_______________________________________________

And:

________________________________________________

" $5\sqrt{a} = 5a^\frac{1}{2}$ " .

________________________________________________

→ The answer is: " $5a^\frac{1}{2}$ " .

Steven has $25 dollars to spend. He spent $10.81, including tax, to buy a new DVD. He needs to save $10.00 but he wants to buy a

Yuliya22 [10]

(25 - 10.81) - 1.38p = 10

p = package of peanuts

25 - 10.81 = 14.19

14.19 - 1.38p = 10

Subtract 14.19 from each side

10 - 14.19 = -4.19

-1.38p = -4.19

Divide both sides by -1.38

p = 3 (roughly, but because you can only buy the whole package, this is the amount you can buy)

He can buy a maximum of 3 packages of peanuts.
