Elements are _____.a chemical substance composed of atoms of two or more different types of atoms
substances that are made up of only one type of atom
subatomic particles with a positive charge
only found on earth
Answers
Answer: substances that are made up of only one type of atom
Step-by-step explanation:
Element is a pure substance which is composed of atoms of similar elements. Example: Carbon (C)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water
The subatomic particles with a positive charge are called as protons and are located in the nucleus of the atom.
Thus elements aresubstances that are made up of only one type of atom.

Ed had a gross income of $3255.29 during each pay period in 2010. If he got paid monthly, how much of his pay was deducted for FICA in 2010
Answers
Answer A
d :the distance in miles
t: the time in hours
v: the speed in miles/hours (vistesse)
d=v*t
==>d=40*4=160(mi)
d=55*x=160==>x=160/55=2.909090... (mi/(mi/h)=h)≈2.91(hours)
The time it would take to drive the same distance at 55 miles per hour is 2.91 hours.
What is the time needed to drive the same distance?
If time varies inversely with speed, as time increases, speed decreases. This means that the faster one travels, the lower the time it would take to reach the destination.
The equation that can be used to represent inverse relation is:
t = k / r
Where k is the constant of proportionality
4 = k/40
k = 160
160 / 55 = 2.91 hours

The ratio of Mark’s pay per hour to Carl’s pay per hour is 3:4 given that Mark takes twice as long as to earn $6.00 as it takes Carl to earn $4.00. This can be obtained by dividing their hourly wages.
What is the required ratio?
Given that, Mark takes twice as long as to earn $6.00 as it takes Carl to earn $4.00.
(Time taken for Mark to earn $6)=2×(Time taken for Carl to earn $4)
Time taken for Mark to earn $3 = Time taken for Carl to earn $4
This means that Mark takes the same amount of time to earn $3.00 as Carl earn $4.00.
Thus the ratio of Mark’s pay per hour to Carl’s pay per hour, 3/4 = 3:4
