Answer:

Step-by-step explanation:

Answer: it will take 17.5 years to double his money in the account.

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $500

A = 500 × 2 = $1000

r = 4% = 4/100 = 0.04

n = 4 because it was compounded 3 times in a year.

Therefore,.

1000 = 500(1 + 0.04/4)^4 × t

1000/500 = (1 + 0.01)^4t

2 = (1.01)^4t

Taking log of both sides, it becomes

Log2 = 4tlog 1.01

0.301 = 4t × 0.0043 = 0.0172t

t = 0.301/0.0172

t = 17.5 years

Diameter:2ft
Radius:1ft
A=3.14*1^2
A=3.14
Multiply by 4
4 squares=12.56ft squared
Formula for a square: A=s^2
A=4^2
A= 16ft squared
To find leftover you need to subtract 12.56 ft from 16 ft to get 3.44 ft squared(A).

OLEGan [10]

The weight of the cat food in pounds is 99 lbs.

<h3>What is a pound?</h3>

The pound, sometimes known as pound-mass, is a unit of mass that is used in both the British imperial and American customary measurement systems.

<h3>How do we convert kg to pounds?</h3>

You multiply a weight by the conversion factor 2.2046 to change a mass measurement from kilograms (kg) to pounds (lbs).

Given that,

Mass of each bag = 7.5 Kg.

Number of bags bought = 6

Firstly, we need to find how much the cat food weighs:

Total weight of cat food = 6 × 7.5

Total weight of cat food = 45kg

Next, we will require to convert the kg into pounds:

1kg = 2.2lb

45 kg = 45* 2.2

45 kg = 99 lbs

Therefore, the weight of the cat food in pounds id 99lbs.

Musya8 [376]
Of course, this statement is FALSE.
Let`s assume that a small town in Nevada had a population of 1,000.
When it lost 20% of its population:
1,000 * ( 1 - 0.2 ) = 1,000 - 0.8 = 800 
After that the same town gained 20 % more people:
800 * ( 1 + 0.2 ) = 800 * 1.2 = 960
960 ≠ 1,000
In the end the town`s population was not the same as it was before the downturm.
