I'm just going to take a chance and say 1.A, and 2.D.
Answer:
45 ways
Step-by-step explanation:
We are given;
there are 3 different math courses, 3 different science courses, and 5 different history courses.
Thus;
Number ways to take math course = 3
The number of ways to take science course = 3
The number of ways to take history course = 5
Now, if a student must take one of each course, the different ways it can be done is;
possible ways = 3 x 3 x 5 = 45 ways.
Thus, number of different ways in which a student must take one of each subject is 45 ways.
Answer:
the area should be 3/4
Step-by-step explanation:
the exponent tells you how many times to multiply the base number by itself.
for 35 the base number or base is 3 and the exponent is 5
the value is 3 x 3 x 3 x 3 x 3 which has 3 multiplied by itself five times
So your question is going in the opposite direction.
Rather than going from a power and expanding it, we have the expanded form and we are asked to write the power
3 x 3 x 3 is written 33
True. all squares have opposite sides which are equal in length. this is the same for rectangles.
