dolphi86 [110]

30 miles for a single gallon.
first we find out how many gallons would be used.
number of gallons = 1020/30
gallons = 34.
and since 1 gallon costs $4.06
34 gallons would cost = 34 x 4.06 = $138.04

A diamond ring was reduced from $999.99 to $699.99. Find the percent decrease in the price. Round the answer to the nearest tent

poizon [28]

Answer:

30.0% decrease.

Step-by-step explanation:

A diamond ring was reduced from $999.99 to $699.99

The decrease is; $999.99 - $699.99 = $300.00

Percentage decrease = $\frac{decrease}{original price}$ × 100

i.e percentage decrease = $\frac{300}{999.99}$ × 100 = 30.0003%

And it equals to 30.0% (rounded off to the nearest tenth of a percent)

Drupady [299]

$\huge \boxed{4a+20}$

We can do this using the distributive property, which states that $a(b+c)=ab+ac$ .

Distribute the $4$ to the $a$ and the $5$ . $4a+4(5)$

Multiply. $\displaystyle \boxed{4a+20}$

So, in Math I am learning Scientific Notation. Can someone show an example and some tips for me as well as the steps to remember

defon

You know how decimals are really long to write, like 0.00000000089? Well, with scientific notation, you can shorten them. Take the decimal I wrote for instance. Using scientific notation, I can change it to 8.9 * 10^-10. The decimal is shortened, and according to the exponent, 10^-10, we move the decimal place for 8.9 to the left ten places, leaving us with 0.00000000089.
