What is -4/5 ÷ (-7/6) in simplest form ??

Orlov [11]

Answer:

$\frac{24}{35}$

Step-by-step explanation:

1) Remove parentheses.

$- \frac{4}{5} \div - \frac{7}{6}$

2) Use this rule: a ÷ b/c = a × c/b.

$- \frac{4}{5} \times \frac{6}{ - 7}$

3) Use this rule: a/b × c/d = ac/bd.

$- \frac{4 \times 6}{5 \times - 7}$

4) Simplify 4 × 6 to 24.

$- \frac{24}{5 \times - 7}$

5) Simplify 5 × -7 to -35.

$- \frac{24}{ - 35}$

6) Move the negative sing to the left.

$- ( - \frac{24}{35} )$

7) Remove parentheses.

$\frac{24}{35}$

Therefor, the answer is 24/35.

If C(x) is the total cost incurred in producing x units of a certain commodity, then the average cost of producing x units of th

nataly862011 [7]

Answer:

x = 2000 cameras

Step-by-step explanation:

C(x) Total cost in producing x units

C- = C(x) /x Average cost of producing x units x > 0

Cannon Precision Instrument

C (x) Total monthly cost for producing x units of M1 cameras

is C(x) = 0.0025x² + 80x + 10000

Then average cost of producing x cameras M1 is

C-(x) = ( 0.0025x² + 80x + 10000) /x

C-(x) = 0.0025x + 80 + 10000/x

Taking derivatives on both sides of the equation

C-´(x) = 0.0025 - 10000/x²

Then

C-´(x) = 0

( 0.0025x² - 10000 ) / x² = 0

0.0025x² - 10000 = 0

x² = 10000 /0.0025 x² = 4000000

x = 2000 cameras
