Answer:

perpendicular

Step-by-step explanation:

separate the two equations

First equation in the form y=mx+c

4y=2x+3z

y=1/2x+3/4z

second equation in the form y=mx+c

8y=3-5x-10z

y=3/8-5/8x-10/8z

Helppppppppppppp. a and b partttt​
PilotLPTM [1.2K]

Answer:

a) 220.17 cm

b) 2127.12 cm²

Step-by-step explanation:

perimeter = circumference

it is the sum of the inner and the outer arc and the 2 side lines of 25.

we know a full circle has 360 degrees. but we only look at a segment of a circle of 150 out of the total of 360 degrees.

the circumference of a circle is

C = 2×pi×r

the 150 degree part is then

C = 2×pi×r×150/360 = 2×pi×r×15/36 = pi×r×15/18 =

= pi×r×5/6

the radius of the inner circle is 20.

=>

Ci = pi×20×5/6 = pi×50/3

the radius of the outer circle is 20 + 25 = 45

Co = pi×45×5/6 = pi×75/2

so, the total perimeter/ circumference is

C = Ci + Co + 25 + 25 = pi×50/3 + pi×75/2 + 50

= pi×100/6 + pi×225/6 + 50 = pi×325/6 + 50 =

= 220.17 cm

the area of the shaded shape is the area of the large circle segment minus the area of the small circle segment.

the area of a circle is

A = pi×r²

the 150 degree part is then

A = pi×r²×150/360 = pi×r²×5/12

so, for the inner circle that is

Ai = pi×20²×5/12 = pi×400×5/12 = pi×100×5/3 = pi×500/3

for the outer circle that is

Ao = pi×45²×5/12 = pi×2025×5/12 = pi×10125/12 =

= pi×3375/4

so, the total area of the shaded shape is

A = Ao - Ai = pi×3375/4 - pi×500/3 = pi×(10125-2000)/12 =

= pi×8125/12 = 2127.12 cm²

HELPP<br> What is the size of the label in square cm??
elena55 [62]

Answer:

226.19

Step-by-step explanation:

area of a cylinder is 2 times pi times radius time height plus 2 times pi times radius squared

radius=6/2=3

height=9

substitute in your values and get 226.19cm squared

We want to factor the following expression:
S_A_V [24]

Answer:

A. (U+V)^2 or (U-V)^2

Step-by-step explanation:

9x^6 + 6x^3y + y^2 \\  \\  =  {(3 {x}^{3} )}^{2}  + 2.(3x^3).y +( y)^2  \\  \\  =  \bigg({3 {x}^{3} } + y \bigg)^{2} \\  \\   = \bigg({3 {x}^{3} } + y \bigg) \bigg({3 {x}^{3} } + y \bigg) \\  \\ \\  \\
