1. The most massive planet in the solar system, Jupiter, has a mass of about 1,898,000,000,000,000,000,000,000,000 kg. Estimate

UNO [17]

Answer:

D. $2*10^{27} kg$

Step-by-step explanation:

Mass of Jupiter is given as 1,898,000,000,000,000,000,000,000,000 kg

Estimating this to the nearest whole number would be = 2,000,000,000,000,000,000,000,000,000 kg (rounding up the the "1,898")

To express this in scientific notation form, simply count how many zeros we have to the nearest whole number, 2.

We have 27 zeros there.

Therefore, we would multiply the whole number, 2, by 10 raise to the power of 27.

An estimate of the mass of Jupiter = $2*10^{27} kg$

To make a salad dressing you mix vinegar and olive oil in the ratio 2:5 how much olive oil is needed with 20 ml of vinegar

eduard

Answer:

Step-by-step explanation:

Set this up as a proportion with the ratios being

$\frac{vinegar}{oil}$ If there is a 2:5 ratio of vinegar to oil, that ratio looks like this:

$\frac{v}{o}:\frac{2}{5}$ and if we are looking for how much oil, x, is needed for 20 ml of vinegar, then that ratio completes the proportion:

$\frac{v}{o}:\frac{2}{5}=\frac{20}{x}$ and cross multiply.

2x = 100 so

x = 50 ml of oil
