Can you help me with this​

Mathematics
1 answer:
disa [49]3 years ago
8 0

Answer:

3

Step-by-step explanation:

Okay, I'm going to skim this down mentally as I type. He has who know how many cubes with a height of 2 inches. The situation does NOT mention the length and their CUBEs so obviously, the dimensions are 2x2x2 making the area 8. He uses 60 inches of foil to wrap all but ONE FACE. This detail makes the question harder. 60 divided by 8? is 7.5. so that strategy wont work. 60 divided by 2 i dunno if that's the answer. so deep thinking goes into the rest of this situation. we dont know the area of each face yet.. so if we make the cube into a square, it would be 2x2 making each face with an area of 4. if he wrapped all but ONE. a cube has 6 faces so 4x5 for each cube wrapped! 4x5= 20. 60 divided by 20 = how many cubes!!! .. the answer is 3!

Write an inequality for x that would give this rectangle an area of at least 300ft sq2
Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

P≥300

300≤P

P=2(L+W)

300≤2(L+W)

L=3

W=x+5

300≤2(3+x+5)

300≤2(8+x)

divide both sides by 2

150≤8+x

minus 8 both sides

142≤x

x is at least 142

width is at least 147

Please help! How on earth do I do this? In the year 2015, Anna bought a new car for $36,000. In 2017, she was told that the valu
Klio2033 [76]

Part A

Purchase Value of Anna's Car in 2015 = $36,000

Depreciated Value of Anna's Car in 2017 = $25,000

We know that the value of the car is depreciating linearly.


From the above data, we can see that the value of the car has reduced by $36,000-$25,000 = $11,000 over 2 years.

⇒ Per year the value has been depreciated by \frac{11000}{2}

⇒ Per year the value has been depreciated by $5,500

So if the value of a car in 2015 is V₀ then value of the car after t years can be determined by the below function:

V (t) = V₀ - (t*5,500), where t indicates the years passed since 2015

OR V (t) = 36,000 - (t*5,500), where t indicates the years passed since 2015

Part B

Suggested value of Anna's car for trade in option in 2018 = $15,000

In 2018, 3 years would have been passed since 2015. Using the value of t = 3 in the function determined in Part A:

V(3) = V₀ - (3*5,500)

⇒ V(3) = 36,000 - (16,500)

⇒ V(3) = $19,000

From the above calculations, we can see that the value of the car in 2018 should be $19,000, however the suggested value for trade in is indicated as $15,000 which is lower than what the value of the car should be. Hence, basis linear depreciation, the $15,000 value is not fair for the car in 2018.
