Answer: If element Q has 11 protons, its atomic <u>number</u> is 11.

Step-by-step explanation:

The atomic number of a chemical element is the total number of protons that each atom of that element has.

In other words: it indicates the amount of protons that is present in the nucleus of an atom.

In this sense, the periodic table of the elements arranges the chemical elements in the form of a table, ordered by their atomic number (number of protons), by their configuration of electrons and their chemical properties.

marusya05 [52]

20% of 89.75 is 17.95
$\frac{20}{100} = \frac{x}{89.75} \\ x = \frac{89.75 \times 20}{100} = \frac{1795}{100} = 17.95$
so :
$89.75 - 19.95 = 71.8$
the Trina's coupon will subtract the answer by 10%:

10%of 71.8 is 7.18
$\frac{10}{100} = \frac{x}{71.8} \\ x = \frac{71.8 \times 10}{100} = \frac{718}{100} = 7.18$
so the final answer is:
$71.8 - 7.18 = 64.62$
she has to pay $64.62

Answer:

1) 250 meters= 0.25 km

2) 12 meters= 0.012km

3) 1 meter= 0.001 km

The constant of proportionality is 1000 meters in 1km (1000 meters)

I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!
