(2.3 x 105)(1.5 x 104) in scientific notation plssss ASAP
zhenek [66]

By using scientific notation we calculated (2.3\times10⁵)(1.5 \times10⁴) we got 345 \times10⁷.

Given that,

(2.3\times10⁵)(1.5 \times10⁴)

By using scientific notation

The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.

Now, we calculate

(2.3\times10⁵)=2.5\times100000=230000

(1.5 \times10⁴)=1.5\times10000=15000

Now,

=230000\times15000

=3450000000

=345 \times10⁷

Therefore, By using scientific notation we calculated (2.3\times10⁵)(1.5 \times10⁴) we got 345 \times10⁷.

Rewrite the equation below so that it does not have fractions.
bearhunter [10]

Answer:

60+10x=6

Step-by-step explanation:

Hi there!

4+\displaystyle \frac{2}{3} x=\frac{2}{5}

To get rid of the fraction \displaystyle \frac{2}{3}, multiply both sides of the equation by 3 (the denominator):

3(4+\displaystyle \frac{2}{3} x)=3(\frac{2}{5})\\\\3*4+\frac{3*2}{3}x =\frac{3*2}{5} \\\\12+2x =\frac{6}{5}

To get rid of the fraction \displaystyle \frac{6}{5}, multiply both sides of the equation by 5 (the denominator):

\displaystyle 5(12+2x) =5(\frac{6}{5})\\\\5*12+5*2x=\frac{5*6}{5} \\\\60+10x=6

I hope this helps!

4-58. Lisa plans to retire on her 61st birthday. On her
mojhsa [17]

Answer:

Lisa invest "$2180.81" in her bank.

Step-by-step explanation:

The given values are:

On Lisa's 62nd birthday,

she withdraw = $10,000

The annuity of $A will remain at 3 percent for 40 years. The retirement pension of $10000 lasts 23 years at rate percentage of 3 but begins 40 years later.

⇒  A\times (\frac{P}{A} ,3 \ percent,40) - 10000 (\frac{P}{A} ,3 \ percent,23)\times \frac{1}{(1.03)40} = 0

⇒  A\times 23.1148 - 10000\times 16.4436\times 0.3066 = 0

⇒  A = 10000\times 16.4436\times \frac{0.3066}{23.1148}

⇒      = 10000\times 16.4436\times 0.0132

⇒      =2180.81 ($)
