3. Andrew deposited some money in the bank at the beginning of the year. At the end of one year, he earned an interest and had $3045 in the bank. This was 101.5% of the amount of money Andrew deposited at the beginning of the year. a) How much did Andrew deposit in the bank at the beginning of the year? b) What was the amount of interest Andrew earned?​


Jawab:

a) Andrew deposited$3000in the bank at the beginning of the year.

b) The amount of interest he earned was $45. The interest rate in that bank is 1.5% per year.

Penjelasan dengan langkah-langkah:

The amount of Andrew's money in the bank at the end of one year is 101.5% of the amount of money he deposited at the beginning of the year:

$3045 = 101.5% × m

(m = the amount of money Andrew deposited at the beginning of the year)

$3045 = 101.5% × m

m = $3045 ÷ 101.5%

   = $3045 ÷ (101.5/100)

   = $3045 × 100/101.5

   = $3000

∴ Therefore, Andrew deposited $3000 in the bank at the beginning of the year.

The amount of interest he earned:

$3045 – $3000 = $45

Because this is the amount of interest in one year, we can say that the interest rate in that bank is 1.5% per year.

5. The ratio of the number of girls to the number of boys in a camp is 2 : 3. 65 girls left the camp and the ratio of the number of boys became 1 : 4. Find the total number of children at the camp at first​


Penjelasan dengan langkah-langkah:

girl:boy =2:3 (let name it as unit )

after 65 girl left

girl :boy =1:4( let name this as part )

equation :

3unit =4part

2unit-65=1part

solve this equation

3u=4p

1u=4p/3

insert the unit

2u-65=1p

2(4p/3)-65= 1p

8p/3-65=1p

8p/3-1p=65

5p/3=65

p= 39

3u=4(39)

3 u= 156

1u=52

total student

5×52 = 260

8. the number of bacteria in a colony is 2^t+1, where t is the number of hours after the first observation. after how many hours will there be 1024 bacteria?​


Jawab:

9,9 or if we round it is around 10 hours

Penjelasan dengan langkah-langkah:

Let say that the expansion equation is written down as:

f(x) = 2^t + 1, where f(x) is the amount of bacteria observed. Therefore, we can finish the question by:

f(x) = 2^t + 1

1024 = 2^t + 1

1023 = 2^t

Since we know that:

a^x = b ⇒ log(a)b = x, then:

t = log(2)1023

t = 9,9 or if we round it is around 10 hours

If anything in concern, don't hesitate to ask question :)
