Required number = HCF of (224 -3), (250 - 3) and (302- 3)
Required number is HCF of 221, 247 and 299. Required number = HCF of 221 and 247 and then HCF of (221 & 247) and 299.

Step (1) HCF of 221 and 247 = 13 [by using Euclid’s division algorithm]

Step (2) HCF of 13 and 299 = 13 [By using Euclid’s division algorithm]

Hence HCF of 221, 247 and 299 is 13. Hence, required number is 13.

To have a remainder 3, we take away 3 from each number first.

<u>Take away 3:</u>
224 - 3 = 221
250 - 3 = 247
302 - 3 = 299

<u>Prime factorisation of each of the numbers:</u>
221 = <span>13 x 17
247 = 13 x 19 
299 = 13 x 23

<u>Find HCF:</u>
HCF = 13

Answer: The largest number that can be divided is 13.</span>

Suppose $1750 is put into an account that pays an annual rate of 4.5%
Yanka [14]

Answer:

The amount in the account after six years is $2,288.98

Step-by-step explanation:

In this question, we are asked to calculate the amount that will be in an account that has a principal that is compounded quarterly.

To calculate this amount, we use the formula below

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

Where P is the amount deposited which is $1,750

r is the rate which is 4.5% = 4.5/100 = 0.045

t is the number of years which is 6 years

n is the number of times per year, the interest is compounded which is 4(quarterly means every 3 months)

we plug these values into the equation

A = 1750( 1 + 0.045/4)^(4 * 6)

A = 1750( 1 + 0.01125)^24

A = 1750( 1.01125)^24

A = 2,288.98

The amount in the account after 6 years is $2,288.98
