ANSWER
a. A variable is an unknown number or value represented by a letter
EXPLANATION
In mathematics, we use letters to represent an unknown quantity or number.
For instance, we can use the letter , t, to represent time taken to cover a given distance.
We can use the letter , s, to represent displacement or distance covered by an object.
The letters that we use to represent the unknown values or numbers are called variables.
The correct answer is A.

Sorry this is late! It would be the last answer, it is just in a different order than mine.
Answer:
The length of the hypotenuse is 37cm
Step-by-step explanation:
we know that the area of the triangle can be found by 1/2bh. we can plug in what we know into this formula to find the height.
a=1/2bh
210=1/2(12)h
210=6h
h=35cm
now, since it's a right triangle, we can find the length of its hypotenuse by using the pythagorean theorem, using c to represent the length of the hypotenuse:
12^2+35^2=c^2
c^2=144+1225
c^2=1369
c=37
so, the hypotenuse is 37cm
Answer:
a. Job A 1. 6 2.12 3.18 4.24 5.30 6.36 Job B 1. 10 2. 14 3.18 4.22 5.26 6.30
b. she will make the same amount of money at 3 hours.
c. Priya should take the first job ( Job A), because even with the 6 dollar bonus for the first hour, the second job (Job B) would be paying less money after 3 hours.
