At a certain company, each employee has a salary grade s that is at least 1 and at most 5. Each employee receives an hourly wage p, in dollars, determined by the formula p = 9.50 + 0.25(s – 1). An employee with a salary grade of 4 receives how many more dollars per hour than an employee with a salary grade of 1?
[ "$1.75", "$1.50", "$0.75", "$1.25" ]
C
Salary grade of 4 is p(4)=9.50+0.25(4–1)=9.50+0.25*3; Salary grade of 1 is p(1)=9.50 + 0.25(1–1)=9.50; p(4)-p(1)=9.50+0.25*4-9.50=0.75. Answer: A.

If more than two stars orbit each other, it is called a multiple star system. Figure below shows two binary star systems orbiting each other. This creates an unusual ...

Which factor has a big impact on coastal climates?
[ "large ocean currents", "ocean waves", "tide", "tsunami" ]
A
Large ocean currents can have a big impact on the climate of nearby coasts. The Gulf Stream, for example, carries warm water from near the equator up the eastern coast of North America. Look at the map in Figure below . It shows how the Gulf Stream warms both the water and land along the coast.

A
An electromagnet is a solenoid wrapped around a bar of iron or other ferromagnetic material. A solenoid is a coil of wire with electric current flowing through it. This gives the coil north and south magnetic poles and a magnetic field. The magnetic field of the solenoid magnetizes the iron bar by aligning its magnetic...

C
You can tell that this sponge is saturated with water because when it is squeezed, the water pours out. When something is saturated with water, it already holds as much water as possible. Compounds called hydrocarbons, which contain only carbon and hydrogen, can also be saturated, but not with water.
