The mass of the sun is 2.13525×10^30 kilograms. The mass of Mercury is 3.285×10^23 kilograms.

Rama09 [41]

Answer:

The mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Step-by-step explanation:

We are given that

Mass of the sun= $M=2.13525\times 10^{30}$ kg

Mass of Mercury, $m=3.285\times 10^{23}$ kg

We have to find how many times greater is the mass of the sun than the mass of Mercury.

Mass of sun/Mass of mercury= $\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}$

Mass of sun/Mass of mercury $=0.65\times 10^{30-23}$

Using the property

$a^x/a^y=a^{x-y}$

Mass of sun/Mass of mercury $=0.65\times 10^{7}$

Mass of sun/Mass of mercury $=65\times 10^5$

Mass of Sun= $65\times 10^5$ times Mass of Mercury

Hence, the mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Bruce saved $35.00 to buy a new video game . The game's original price was $42.00, but it was on sale for 30% off. The sales tax

fenix001 [56]

Answer:

The answer to your question is Yes, he can buy it.

Step-by-step explanation:

Data

Money saved = $35

Original Price = $42

Discount = 30%

Tax = 5 %

Process

1.- Calculate the price of the Video game with the discount

$42 --------------------- 100%

x --------------------- 30%

x = (30 x 42) / 100

x = $ 12.6

Price with discount = 42 - 12.6

= $ 29.4

2.- Calculate the price of the Video game plus taxes

$29.4 ------------------- 100%

x ------------------- 5%

x = (5 x 29.4) / 100

x = 147 / 100

x = 1.47

Price plus taxes = 29.4 + 1.47

= $ 30.87

3.- Conclusion

Bruce can buy the Video game because he saved $35 and the video game plus taxes cost $30.87.
