A pyramid has a square base with sides of length s. The height of the pyramid is equal to of the length of a side on the base. W
Kobotan [32]

Answer:²

V = (1/3)s³

Step-by-step explanation:

The area of a square base with side length s is A = s².  The volume of this pyramid is thus V = (1/3)s²h, where h represents the height.  We are told that the height is equal to s.  Thus, V = (1/3)s³.  This matches Answer C.

Note:  when possible answer choices are given to you, please share them.  Also, please enclose fractions inside parentheses to eliminate ambiguity.

A line that includes the point (7,4) and has slope of 8
Art [367]

So I assume you are trying to find the equation of the line.

So you are gonna use this equation:

y=mx+b

So the x and y are your x and y coordinate pair and the m is the slope. So now you just substitute and solve for b:

4=8(7)+b

4=56+b

subtract 56 on both sides

-52=b

so now lets plug this into the equation of the line:

y=8x+(-52)

hope this helps!

An automobile factory is assembling cars and they need to have all of the parts in stock at the assembly line. each car needs fo
ELEN [110]

The formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D

<h3>Equation</h3>

  • Number of tires needed by each car = 4
  • Number of spare tires needed by each car = 1

Total tires needed by each car = 4 + 1

= 5

  • Number of cars produced per day = c

Total number of tires, t needed for c cars.

Number of tires needed, t = Total tires needed by each car × Number of cars produced per day

t = 5 × c

t = 5c

For instance,

if 5 cars are produced per day

Number of tires needed, t = Total tires needed by each car × Number of cars produced per day

t = 5c

= 5 × 5

t = 25 tires

Therefore, the formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D
