Grant's credit card has an apr of 11.28% and it just changed its compounding period from monthly to daily . What happen to the i

madreJ [45]

Answer:

C. It will increase by about 0.6%

Step-by-step explanation:

Since, the effective interest rate is,

$r=(1+\frac{i}{n} )^{n} -1$

Where, i is the stated interest rate,

n is the number of compounding periods,

Here, i = 11.28 % = 0.1128,

n = 365 ( 1 year = 365 days ),

Hence, the effective interest rate would be,

$r=(1+\frac{0.1128}{365})^{365} -1$

=0.119388521952

Now, the changes in effective interest rate = Effective interest rate - Stated interest rate

= 0.119388521952 - 0.1128

= 0.006588521952 ≈ 0.006 = 0.6 %

Hence, It will increased by about 0.6 %,

Option A is correct.

Hope this helps :)

Two percent of Jennies skin cells were burned when she escaped from a fire. If

andreev551 [17]

$1.813*10^{12}$ cells of Jennies skin were not burned.

Step-by-step explanation:

Given,

Burned skin cells = $3.7*10^{10}$

This represents 2% of total skin cells.

Let,

x represents the total number of skin cells.

2% of x = $3.7*10^{10}$

$\frac{2}{100}x=3.7*10^{10}\\\\0.02x=3.7*10^{10}$

Dividing both sides by 0.02

$\frac{0.02x}{0.02}=\frac{3.7*10^{10}}{0.02}\\\\x=1.85*10^{12}$

Number of not burned cells = Total - burned

Number of not burned cells = $1.85*10^{12}-3.7*10^{10}$

Number of not burned cells = $1.813*10^{12}$

$1.813*10^{12}$ cells of Jennies skin were not burned.

SIZIF [17.4K]

Answer:

Step-by-step explanation:

i believe you just have to add the fractions together since the denominator are the same :)

$\frac{6}{8} + \frac{5}{8} = \frac{6 + 5}{8} = \frac{11}{8}$

So in total Hazel can produce $\frac{11}{8}$ Liters of juice
