Answer: 35.328 cubic inches.
Step-by-step explanation:
Volume of square pyramid =
, where a = length of base , h = height
Given: For a square pyramid
a= 4.8 cm and h = 4.6
Then, Volume = 

Hence, the volume of a pyramid with a square base = 35.328 cubic inches.
Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A =
(14 × 4) = 28
Answer:

Step-by-step explanation:
Mr.Mole's digging can be described by a linear model of general equation:

Where "m" is the rate at which he descends. Note that since the function A(t) measure his altitude relative to the ground, the rate "m" must be negative.


The constant "c" is his starting position. To find this value, assign the given data at t = 5 min to the equation above

Therefore, the function A(t) is described by the following formula:

Algebraic expression always have a percent the x-ray and white rate that you have to multiply and flip around so I could get a total answer
Each time in the sequence, 20 is subtracted.
