Next, you are going to use the "keep, change, change" method. If you don't know what it means you are basically going to keep the first number the same, change the sign to subtraction, and finally change the negative number into a positive number.
13+-3
13-3
10
You are still getting the same results even if you didn't use this method.
Answer:
126.56
Step-by-step explanation:
120 - 8 = 112
112 x .13 = 14.56
112 + 14.56 = 126.56
Answer: B.
Step-by-step explanation:
See attached. We examine the equation and decide which situation, or problem, models it correctly.
The first thing you should do in this case is to calculate the volume of the square pyramid, which will be given by:
V = (Ab * h) / 3
Where,
Ab: Area of the base.
h: height of the pyramid.
Substituting the values we have:
V = ((10 * 10) * (11)) / 3
V = 366.6666667 cm ^ 3
We now calculate the volume of each cube, which will be given by:
V '= L ^ 3
Where,
L: sides of the cubes.
Substituting we have:
V '= (3) ^ 3
V '= 27 cm ^ 3
The number of cubes will be:
N = (V) / (V ')
N = (366.6666667) / (27)
N = 13.58024691
