Step-by-step explanation:

6 times 9 is 54.

54 divided by 2 is 27 volume ( recipitor) is 27 for no.1

6 times 7 is 42

42 divided by 2 is 21 is the recipitor or volume for no.2

there fore a has a bigger base surface

as base is measured by recipitorial angles

sorry if this isnt the right answer or what u wanted but I know it this way

Answer:

Pyramid A has greater surface area

Step-by-step explanation:

<u>Pyramid A </u>

A=lw+l√((w /2)²+h²)+w√((l /2)²+h²)

l=w= 6 m

h= √7²-3³= √40 ≈ 6.33 m

A≈ 120 m²

<u>Pyramid B </u>

A=lw+l√((w /2)²+h²)+w√((l /2)²+h²)

l= 6 m

w=4 m

h= √9²-2³= √73 ≈8.54 m

A≈ 112.83 m²

What system of equations is shown on the graph below?
erma4kov [3.2K]

Answer:

The equation of the line passing through the points (-2,0) and (0,-4)

\frac{y - y1}{x - x1}  =  \frac{y2 - y1}{x2 - x1}

\frac{y - 0}{x  - ( -  2)}  =  \frac{ - 4 - 0}{0 - ( - 2)}  =  \frac{ - 4}{2}  =  - 2

y =  - 2(x + 2) \\ y =  - 2x - 4

2x + y =  - 4

The equation of the line passing through the points (0,-2) and (4,0)

\frac{y - y1}{x - x1}  =  \frac{y2 - y1}{x2 - x1}  \:

\frac{y - ( - 2)}{x - 0}  =  \frac{0 - ( - 2)}{4 - 0}

\frac{y + 2}{x}  =  \frac{1}{2}

x - 2y = 4

Option B

x minus 2 y = 4 and 2 x + y = negative 4

How to find what is force if pressure and are is given please answer I will mark brainiest
levacccp [35]

Answer: Pressure and force are related, and so you can calculate one if you know the other by using the physics equation,

P = F/A. Because pressure is force divided by area,

its meter-kilogram-second (MKS) units are newtons per square meter,

or N/m2.

olga nikolaevna [1]

Step-by-step explanation:

A.C

B.2w + 2(w + 3) = 72

2w + 2w + 6 = 72

4w + 6 = 72

4w = 72 - 6

4w = 66

w = 16.5
