1st one 17/100 2nd one 0.25

Because 0.17 would be like 17% out of 100% so the fraction simplified is 17/100

2. Since the area of a square is length×length
But according to the question we are asked to find the length and the area is given so we will have to solve this
L×L= area
L^2=0.25
Square root both sides
L=√0.25
L=0.5
Therefore the length of the square is 0.5

A new car is purchased for 20000 dollars. The value of the car depreciates at 12. 5% per year. What will the value of the car be

Georgia [21]

To solve the problem we need to know about depreciation.

<h2>Formula of Depreciation</h2>

The formula of depreciation is given as,

$A = P(1-r)^t$

where,

A is the value of an object after t years of time,

P is the value of the object at the beginning, and

r is the rate of depreciation.

The value of the car after 11 years is $4,603.81.

<h2>Explanation</h2>

Given to us

Cost of Car at the beginning, p = $20,000
Rate of depreciation, r = 12.5%
Time, t = 11 years

<h3>Value of the car after 11 years</h3>

Substituting the values in the formula of depreciation,

$A = P(1-r)^t$

Value of the car after 11 years = $P(1-r)^n$

$= \$20,000(1-0.125)^{11}\\\\
= \$20,000\times 0.23\\\\
= \$4,603.822 \approx \$4,603.81$

Hence, the value of the car after 11 years is $4,603.81.

A student answered this story problem. Use estimation to check the student's answer. Lizzie has $49. Her older sister has $184.

Anna35 [415]

Answer:No the student was not right.Neither of the estimations were right because she did not estimate at al.

Step-by-step explanation:

1.Round 49 to the nearest ten: 50.

2.Round 184 to the nearest ten:180.

3.Add 50+180 to get 230.

The student was not right because she did not estimate 49 nor 184.

W/18=3<br> I don't understand

Travka [436]

If you want to solve for w:

w/18= 3
multiply both sides by 18

(w/18)(18)= (3)(18)
18 "cancels out" on the left side

w= 54

CHECK
54/18= 3
3= 3

ANSWER: w= 54

Hope this helps! :)
