The length, width, and area will be 25m, 15m, and 375m².

<h3>How to calculate the area?</h3>

From the information given, the scale in the drawing is 2cm : 5m and the length and width are given as 10cm and 6cm respectively.

Length = 10cm = 10 × 2.5 = 25m

Width = 6cm = 6 × 2.5m = 15m

Area = Length × Width

Area = 25 × 15

Area = 375m²

Therefore, the area is 375m².

a car was valued at $41,000 in the year 2009 by 2013 the car value has depreciated to 19,000 if the car value continues to by th
lubasha [3.4K]

Answer:

$6,376.92

Step-by-step explanation:

-Let d be the rate of depreciation per year.

-Therefore, the value after n years can be expressed as:

A=P(1-d)^n\\\\A=Value \ after \ n  \ years\\P=Initial \ Value\\d=Rate \ of \ depreciation\\n=Time \ in \ years

#We substitute for the years 2009-2013 to solve for d:

A=P(1-d)^n\\\\19000=41000(1-d)^4\\\\0.475=(1-d)^4\\\\d=1-0.475^{0.25}\\\\d=0.1698

#We then use the calculated depreciation rate above to solve for A after 10 yrs:

A=P(1-d)^n\\\\=41000(1-0.1698)^{10}\\\\=\$6,376.92

Hence, the value of the car after 10 yrs is $6,376.92

The variable z is directly proportional to x, and inversely proportional to y. When x is 7 and y is 7, z has the value 2. What i
Rina8888 [55]

Answer:

z = \frac{5}{3}

Step-by-step explanation:

Given z is directly proportional to x and inversely proportional to y then the equation relating them is

z = \frac{kx}{y} ← k is the constant of proportionality

To find k use the condition x = 7, y = 7 and z = 2

k = \frac{zy}{x} = \frac{2(7)}{7} = 2

z = \frac{2x}{y} ← equation of proportionality

When x = 10 and y = 12, then

z = \frac{2(10)}{12} = \frac{20}{12} = \frac{5}{3}
