The constant of proportionality is 3.

Step-by-step explanation:

Constant of proportionality is found by doing k = [tex]\frac{y}{x}[/tex]. Point (2,6) is on the line, so if we plug in point (2, 6) into the equation to solve for the constant of proportionality, we get [tex]k=\frac{6}{2}[/tex] or k = 3. The constant of proportionality is 3.

Find area of both triangles 6 x 6 because there are 2

Triangles area 36

Rectangle area= 9.25 x 20=185

Subtract  185-36=149

Answer and Step-by-step explanation:

First, you would find the area of the un-shaded portion, then we would add those together and subtract it from the area of the entire rectangle.

Base and Height (of triangle) is 6.

[tex]\frac{6*6}{2}[/tex] = 18

[tex]\frac{6*6}{2}[/tex] = 18

Area of Rectangle (length times width).

[tex]9\frac{1}{4}[/tex] × 20 = 185

185 - 36 = 149

Answers

Answer:

Length of the Area = 50mtrs

Width of the Area  = 20mtrs

Step-by-step explanation: Let the x be the length and y be the width of the Area. So we can write x = 2 y + 10 and x y = 1000 or ( 2 y + 10 ) y = 1000 or 2 y 2 + 10 y = 1000 or 2 y 2 + 10 y − 1000 = 0 or y 2 + 5 y − 500 = 0 or y 2 + 25 y − 20 y − 500 = 0 or y ( y + 25 ) − 20 ( y + 25 ) = 0 or ( y + 25 ) ( y − 20 ) = 0 or y + 25 = 0 or y − 20 = 0 or y = − 25 Invalid value contains negative sign or y = 20 So Width of the Area is 20 ----------Ans By plugging the value of y = 20 in the eqn x = 2 y + 10 we get Length of the Area = 2 × 20 + 10 = 50 -------------Ans

so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together

l= length

w=width

a=area

4*8=32

4*8=32

6*4=24

6*8=48

6*8=48

48+48+24+24+32+32=208

for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.

for the triangles you're gonna wanna use the equation 1/2b*h=a

b= base

h=height
