Ok if half are female that means 40 than 80 more for each of them because they all produce 80 so 80  times 40  = 3200 your gonna do the same 2 more times because of 3 generations so 3200 times 3 = 9600 in total

Answer with steps please i have 1 mark on this with steps

Answer:

56cm²

Explanation:

the amount of material he needs would be the total surface area of the box. surface area can be calculated by finding the sum of surface area of all the sides of the box. since the opposite sides are equal, we can find the surface area of 3 different sides and then multiply it by 2.

(4 + 4) + (4 + 6) + (6 + 4) × 2

= 8 + 10 + 10 × 2

= 28 × 2

= <u>56cm²</u>

i hope this helps! :D

The coordinate plane has the following points A=(2, 1), B=(5, 1), C=(7,2), and 1 point
dusya [7]

Answer:

<em>d = 3</em>

Step-by-step explanation:

Coordinate Plane

The image provided shows the four points given:

A=(2, 1), B=(5, 1), C=(7,2), D=(4,2).

It can be clearly seen the length of CD is just the difference of their x-coordinates:

CD = 7 - 4 = 3

We can also use the formula of the distance.

Given two points C(x,y) and D(w,z), the distance between them is:

d=\sqrt{(z-y)^2+(w-x)^2}

d=\sqrt{(2-2)^2+(7-4)^2}

d=\sqrt{0^2+3^2}

d=\sqrt{9}

d = 3

Write an equation rectangular room 3 meters longer than it is wide and its perimeter is 18 meters
Anon25 [30]

width = x

length = 3 + x

perimeter = x + x + ( 3 + x ) + (3+x)

18 = x + x + ( 3 + x ) + (3+x)

x + x + ( 3 + x ) + (3+x) = 18

6 + 4x = 18

4x = 12

x = 3
