Answer:
72.8 gal (to the nearest tenth)
Step-by-step explanation:
Divide 33.5 by 78.25 to find how much gas is needed for 1 mile, then multiply this by 170:
(33.5 ÷ 78.25) x 170 = 72.77955272.. = 72.8 gal (to the nearest tenth)
The area of all paralellograms can be found by
area=base times height
so
area=26 and 1/2
height=6 and 5/8
convert to improper fractions for ease of use
26 and 1/2=52/2+1/2=53/2
6 and 5/8=48/8+5/8=53/8
so
area=height times base
53/2=53/8 times base
multiply both sides b 8/53 so that we clar the fraction (53/8 times 8/53=424/424=1)
(53 times 8)/(53 times 2)=1base
8/2=1base
4=base
answer is base=4 units

The statement is correct about the radionuclide the atomic number is 31, the mass number is 67, and its symbol is superscript 67 subscript 31 baseline upper g a.
To answert the question, we need to know what an atom is.
<h3>What is an atom?</h3>
An atom is the smallest indivisible part of a substance. It is represented by letters.
- It has an atomic number which is the number of protons or electrons present in an atom and is written as a subscript in from of the letter symbol.
- It has a mass number which is the number of protons plus neutrons in an atom and is written as a subscript in from of the letter symbol.
So, since the atom of this radionuclide contains 31 protons and 36 neutrons.
So, its atomic number is 31. Its mass number is number of protons + number of neutrons = 31 + 36 = 67. Its symbol is superscript 67 and subscript 31.
So, the statement is correct about the radionuclide the atomic number is 31, the mass number is 67, and its symbol is superscript 67 subscript 31 baseline upper g a.
