1) A population of genetically modified
TiliK225 [7]
This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.

So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.

There will be 40 mosquitoes after ten months.

Hi, I don't need this really fast, but I really don't understand how to do surface area and lateral surface area with rectangula
ipn [44]

Answer:

The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid.

A circle has a circumference of 450cm
anzhelika [568]

The circumference of the circle is actually the perimeter ( length of the boundary ) of the circle . And a part of the circle which lies between two distinct points on the circumference of the circle is called an arc . If the length of the arc is less than half the circumference , it is called minor arc and remaining portion which is more than half of the circle ( but natural ) is called major arc .

When these two points , which make the arc are joined separately to the centre of circle , these arms make angle at the centre . This is called the angle subtended by the arc at the centre of the circle .

There is a beautiful logical relation exists between arc length and the angle , the arc makes ( subtends ) at the centre of the circle . This relation is as under , the wholle circle subtends an angle of 360 degree at the centre . Half the circumference subtendr 360 / 2 ie 180 degree at the centre . The logical relation becomes Arc Length = Circumference × angle in degrees it ( the arc ) subtends at the centre of the circle / 360 degree . So the answer is very simple :- The Arc Length = 36 × 90 / 360 or 9 units ( may be centimetres or metres or inches , feet , yards , etc ) . Which is definitely length of the minor arc . The length of the major arc ( remaining portion of the circumstance ) is 36 - 9 = 27 units . Hence the required answer of the sum is 9 units .

The length of a rectangle is 5cm less than twice the width. The perimeter is 44cm.
Veronika [31]

Answer:

Width = 9

Length = 13

Step-by-step explanation:

width = w

length = L

w(2) - 5 =  L

w + w + L + L = 44

44 + 5 + 5 = 54

54/6 = 9

9(2) = 18 - 5 = 13

w = 9

l = 13

Check:

9 + 9 + 13 + 13 = 44

9(2) = 18 - 5 = 13

Y = 1/4x

My method is counting the boxes over then under. (really hard to explain, would have to show you)

ymYou could how many boxes that is in between the horizontally then vertically.

The number of boxes it goes past horizontally is the denominator or bottom number and vertically is the numerical or top number in a fraction.
