I need help with math the question is

velikii [3]

Answer:

$P=2(S-lw)/h$

Step-by-step explanation:

we have that

The formula for the surface area of the enclosed space is

$S=lw+0.5Ph$

Solve for P

That means ------> isolate the variable P

Subtract lw both sides

$S-lw=lw+0.5Ph-lw$

$S-lw=0.5Ph$

Multiply by 2 both sides

$2(S-lw)=(2)0.5Ph$

$2(S-lw)=Ph$

Divide by h both sides

$2(S-lw)/h=Ph/h$

$2(S-lw)/h=P$

Rewrite

$P=2(S-lw)/h$

Find the volume of a pyramid with a square base, where the perimeter of the base is 7.3\text{ ft}7.3 ft and the height of the py

Cloud [144]

Answer:

$V=6.66\ ft^3$

Step-by-step explanation:

The perimeter of the square base of a pyramid = 7.3 ft

The height of the pyramid, h = 6ft

The perimeter of a square is given by :

P = 4s, s is the side of square

7.3 = 4s

s = 1.825 ft

The volume of a pyramid is given by :

$V=\dfrac{lbh}{3}$

Here, l = b = 1.825 ft

So,

$V=\dfrac{1.825\times 1.825\times 6}{3}\\\\V=6.66\ ft^3$

So, the volume of the pyramid is equal to $6.66\ ft^3$ .

A line includes the points (6,9) and (14, 17). What is its equation in slope-intercept form?

Firlakuza [10]

Answer:

y = x + 3

Step-by-step explanation:

Given: (6,9) (14, 17)

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{17-9}{14-6}=\frac{8}{8}=1$

slope, m = 1

Equation of line ⇒ y=mx+b

y = 9 , x = 6 , m = 1, b = ?

9 = 1*6 + b

9 = 6 + b

b = 9 - 6 = 3

Therefore, the equation of line will be:

y = 1x + 3

y = x + 3
