Find the area of this irregular polygon.
Rainbow [258]

Answer:

970m^{2}

Step-by-step explanation:

This polygon can be divided in two figures: one is a triangle, an the other one is a square.

We'll begin calculating the triangle's area, using the following formula:

At= \frac{b.h}{2}

Where:

H= height = 30 m

B = 9 m + 9 m + 20 m = 38 m

As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.

At= \frac{38 m .30 m}{2}

At= \frac{1140 m^{2} }{2}

At= 570 m^{2}

Now we are going to calculate the square's area, that is much more simple:

As= L^{2}

Where:

L=20 m

As= (20 m)^{2} = 400m^{2}

To know the whole figure's area, we add up both areas:

A = At+As = 570m^{2} +400m^{2}=970m^{2}

State whether the slope of the line is positive, negative, zero, or undefined.
Rudiy27

The slope of the line is equal to \tan \alpha, where angle \alpha is angle of line incline to the positive x-direction.

  • When \alpha is acute, then slope is positive;
  • When \alpha is obtuse, then slope is negative;
  • When \alpha is right, then slope is undefined;
  • When \alpha is zero, then slope is equal to 0.

In your case angle of inclination is obtuse and slope is negative.

Answer: correct choice is B

There are 11 candidates for three postions at a restaraunt. One postion is for a cook. The second position is for a food server
LenaWriter [7]

Answer:

165 combinations possible

Step-by-step explanation:

This is a combination problem as opposed to a permutation, because the order in which we fill these positions is not important.  We are merely looking for how many ways each of these 11 people can be rearranged and matched up with different candidates, each in a different position each time.  The formula can be filled in as follows:

₁₁C₃ = \frac{11!}{3!(11-3)!}

which simplifies to

₁₁C₃ = \frac{11*10*9*8!}{3*2*1(8!)}

The factorial of 8 will cancel out in the numerator and the denominator, leaving you with

₁₁C₃ = \frac{990}{6}

which is 165

From a piece of paper, Sam cuts a rectangle with a length that is 2 inches (in.) longer than the width. He tapes a straw to the
Ksivusya [100]

Answer:

c)A cylinder with a volume of  π(w³ +2w² )in³

 where w represents the width of the cylinder.

Step-by-step explanation:

A cylinder with a volume of  π(w³ +2w² )in³

 where w represents the width of the cylinder.

The  volume of a cylinder is given by  V=Bh or V=πr²h

where B is the area of the base and h is the height of the cylinder.

V=πr²h-------equation1

V= π(w³ +2w² )--------- equation2

Comparing equation 1 and equation 2

πr²h=π(w³ +2w² )

r²h=(w³ +2w² )

r²h= w²(w +2 )

Taking w² common leaves w+2 which gives the height or length of the cylinder.

Therefore radius = width and height = length which gives the volume of the cylinder.

One number is 5 more than another.
Ganezh [65]

Answer: 29 and 24

Step-by-step explanation:

Since one number is 5 more than another

53-5 = 48

Then we divide that by two to get the value of one of the two numbers

48/2= 24

In order to get the number which is 5 more than the other, we add 5

24+5= 29

So the two numbers would be 29 and 24.

Check:

29+24= 53
