Depreciation formula: starting value x (1 - percent of decrease)^years

Change 0.9% to a fraction by dividing by 100:

0.9/100 = 0.009

750 x (1-0.009)^7

750 x 0.991^7 = $704.01

The answer is $704.01

Answer:

\dfrac{149}{40}

\dfrac{38}{15}

Step-by-step explanation:

(\dfrac{7}{8} + \dfrac{4}{5}) - (\dfrac{9}{20} + \dfrac{-5}{2}) =

= (\dfrac{7}{8} \times \dfrac{5}{5} + \dfrac{4}{5} \times \dfrac{8}{8}) - (\dfrac{9}{20} + \dfrac{-5}{2} \times \dfrac{10}{10})

= (\dfrac{35}{40} + \dfrac{32}{40}) - (\dfrac{9}{20} + \dfrac{-50}{20})

= \dfrac{67}{40} - (-\dfrac{41}{20})

= \dfrac{67}{40} + \dfrac{41}{20} \times \dfrac{2}{2}

= \dfrac{67}{40} + \dfrac{82}{40}

= \dfrac{149}{40}

(-\dfrac{6}{4} + \dfrac{3}{2}) + (\dfrac{6}{5} + \dfrac{4}{3}) =

= (-\dfrac{3}{2} + \dfrac{3}{2})+ (\dfrac{6}{5} \times \dfrac{3}{3} + \dfrac{4}{3} \times \dfrac{5}{5})

= 0 + \dfrac{18}{15} + \dfrac{20}{15}

= \dfrac{38}{15}

HELP PLZ ASAP HELP
Basile [38]

Answer:

4.5 Cubic Feet

Step-by-step explanation:

1. You want to find the volume of the box. (Length x width x height)

2.5 x 2 x 1.5 = 7.5

2. The present has a volume of 3 cubic feet, so you would subtract that from the volume of the box.

7.5 - 3 = 4.5

3. The volume of the empty space in the box is 4.5 cubic feet.

Hope this helped! :)

It looks easy but I kinda don't understand the graph ​
Mariana [72]

neverminding the dots or points on the line, we can see that the line is using a solid stroke, is a solid line, as opposed to a dashed one.

A solid line means, "the borderline is included in the inequality", so that means either ⩾ or ⩽, depending on how you'd write the expression.

so we can say

y ⩽ "some expression in x-terms here"

or we can say

"some expression in x-terms here" ⩾ y

basically the same thing.

the cat is red

and

red is the cat

same thing, depends on how you write it.

Solve for x.<br><br> 12 = x + 3 X=_____
alexandr1967 [171]

For this case we must find the value of the variable "x" of the following equation:

12 = x + 3

So, we follow the steps:

Subtracting 3 from both sides of the equation we have:

12-3=x+3-3

Different signs are subtracted and the sign of the major is placed:

9 = x\\x = 9

Thus, the value of x is 9.

Answer:

x = 9
