3) Lane and Zack purchased a house for $245,000 in 2016. The house loses 4% of its value each year,
kherson [118]

Answer:

In 2030 Lane & Zack's house be worth $65,739.27.

Step-by-step explanation:

Here, as we know The value of  property =  $245,000

Rate of depreciation  = 4% of its present value

Time = From 2016 to 2030 = 14 years

Now, here: Amount depreciated = -( COMPOUND INTEREST on the value)

<u> Step 1: CALCULATE THE COMPOUND INTEREST on P = $245,000</u>

A = P(1 + \frac{r}{100} )^t\\\implies A  = (245,000)(1 + \frac{4}{100} )^{14}  = (245,000)(1 + \frac{4}{100} )^{14}\\=245,000 (\frac{104}{100} )^{14}  = 424,260.73

or, AMOUNT = $424,260.73

Now, AMOUNT  = Compound I + Principal

⇒Compound I = A - P =  $424,260.73 - $245,000 =$ 179,260

So, the amount of the house  by which house depreciates  = $ 179,260

⇒The depreciated value  = Actual Value  - The depreciated amount

= $245,000 - 179,260 = $65,739.27

Hence, in 2030 Lane & Zack's house be worth $65,739.27.

Using the graphing function on your calculator, find the solution to the system
stealth61 [152]

Answer:

It has infinite solutions.

D. More than 1 solution

Step-by-step explanation:

$\left \{ {{3y - 9x = -6} \atop {5y - 15x = -10}} \right. $

$\left \{ {{3y(-5) - 9x(-5) = -6(-5)} \atop {5y(3) - 15x(3) = -10(3)}} \right. $

$\left \{ {{-15y +45x = 30} \atop {15y - 45x = -30}} \right. $

0+0=0

or

5y = 15x - 10\\y = 3x - 2

3(3x-2) - 9x = -6

0=0

Please help me I suck at math
daser333 [38]

Answer:

1) 27/128 ft³

2) 40cm³

Step-by-step explanation:

1) The diagram is a cuboid not a prism.

Volume of the shape = Length × Breadth × Height

Given the following dimension

Length = 3/8 ft

Breadth = 3/4 ft

Height = 3/4 ft

Volume = 3/8 × 3/4 × 3/4

Volume of the shape = 27/128 ft³

2) Volume of a rectangular prism = Base Area × Height

Given base area = 12cm²

Height of the prism = 3 1/3 cm

Volume = 12 × 3 1/3

Volume = 12 × 10/3

Volume = 4 × 10

Volume of the prism = 40cm³
