An investment of $500 earns interest at an annual interest rate of 13%. The equation for this investment is B = 500(1.13)t, wher

pickupchik [31]

Answer: C) $B= 500(1.101)^{12t}$

Step-by-step explanation:

Given : The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years.

For monthly interest , Rate = $\dfrac{r}{12}$

Time = 12 t [ 1 year = 12 months ]

As r = 0.13 , so rate = $\dfrac{0.13}{12}\approx0.010$

Now, the equation will be :

$B=500 (1+0.101)^{12t}$

$\Rightarrow\ B= 500(1.101)^{12t}$

Correct option : C) $B= 500(1.101)^{12t}$

Write 8,840 in scientific notation. 88.4 x 103 8.84 x 10−3 8.84 x 103 88.4 x 10−3 plzz help

lozanna [386]

Answer:

8.84 x 10^3

Step-by-step explanation:

first, you need to turn the digits in 8840 so it is lower than 10 and at least 1

so 8840 ÷ 1000 gives us 8.840, or 8.84

Then, we need to add the multiplication that makes the original number

8.84 x 1000 = 8840

We simplify this by counting the factors zeros

1 0 0 0 = 3 zeros

Finally, but the amount of zeros in the exponent

8.84 x 10^3

Rob is setting up a model train track that is 3 and 3 over 8 feet long. No telephone pole is needed at the start of the track. H

Free_Kalibri [48]

The number of 3/8 foot sections that 3 3/8 feet can be divided into is found using division:

$\dfrac{\left(3\frac{3}{8}\right)}{\left(\frac{3}{8}\right)}=\left(3+\dfrac{3}{8}\right)\cdot\dfrac{8}{3}\\\\=\dfrac{3\cdot 8+3}{8}\cdot\dfrac{8}{3}=\dfrac{9\cdot 3\cdot 8}{3\cdot 8}\\\\=9$

Rob needs 9 telephone poles.
