san4es73 [151]

Answer: Andy should invest RS. 2784.19 for 12 years .

Step-by-step explanation:

Since we have given that

Amount = Rs. 5000

Time = 12 years

Rate of interest = 5%

So, We need to find the sum:

Using "Compound interest" , we get :

A=P(1+r)^t\\\\5000=P(1+0.05)^{12}\\\\5000=P(1.05)^{12}\\\\\dfrac{5000}{1.05^{12}}=P\\\\2784.19=P

Hence, Andy should invest RS. 2784.19 for 12 years .

san4es73 [151]

Answer: (D) Amber spends time sleeping than she does at school.

Step-by-step explanation:

Given that :

• Amber spends 3/16 of each day doing homework.

• Amber spends 0.25 of each day at school.

• Amber spends 1/3 of each day sleeping.

Hence,

Amber spends 0.1875 of a day doing homework, which is (0.1875 * 24) = 4.5 hours

0.25 of each day at school ; (0.25 * 24) = 6 hours

1/3 of each day sleeping ; (1/3 * 24) = 8 hours

Time spent sleeping = 8 hours

Time spent in school = 6 hours

<span>The entire expression should be subtracted from 30. To subtract the quantity, distribute the negative sign, which changes the signs on the terms. So, the –2 changes to positive and gets added to 30 instead of subtracted from it.
