Find the surface area of the prism.
Maurinko [17]

Answer:

326m²

Step-by-step explanation:

Find the area of each side and find the total sum from each individual area:

2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326

So the surface area of the prism is 326m²

Hey user!!!

given the radius of the cylindrical mold is 2 inches and height is 3 inches.

volume of the cylindrical mold = πr²h

= 3.14 × 2 × 2 × 3

= 37.68 in³


radius of the spherical mold is given = 2 inches

volume of the spherical mold = 4/3πr³

= 4/3 × 3.14 × 2 × 2 × 2

= 100.48/3 in³


difference between the amount of wax needed = 37.68/1 - 100.48/3

= ( 113.04 - 100.48 ) / 3

= 12.56/3

= 4.186...

so approximately 4.19 in³

hence, correct option is 4.19 in³


cheers!!!

What is the solution to the system: 9x+3y=24 2y+4x=8
egoroff_w [7]

Answer:

x = 4, y = -4

Step-by-step explanation:

9x + 3y = 24

3x + y = 8                       divide both sides by 3

y = 8 - 3x                        subtract 3x from both sides

2y + 4x = 8

2(8 - 3x) + 4x = 8             replace y with 8 - 3x

16 - 6x + 4x = 8                distributive property

-6x + 4x = 8 - 16               subtract 16 from both sides

-2x = -8                            divide both sides by -2

x = 4

y = 8 - 3x

y = 8 - 3(4)                        replace x with 4

y = 8 - 12

y = -4
