3/4 = 30/40 so therefor b 33/40 is greater than 30/40 is correct
Answer:
x=14
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−9)=20
Step 1: Simplify both sides of the equation.
4(x−9)=20
(4)(x)+(4)(−9)=20(Distribute)
4x+−36=20
4x−36=20
Step 2: Add 36 to both sides.
4x−36+36=20+36
4x=56
Step 3: Divide both sides by 4.
4x

22,470, because you look it up a calculator
5*4032=5*(4000+30+2)=5*4000+5*30+5*2, it helps to break down the number to smaller bits,
Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²
