Because the middle point is in the center of the square, the triangle containing angle 2 is isosceles and right (since two sides are equal to half the square's side length), so angle 2 measures (180-90)/2=45 degrees.

Brody is organizing his action figures on a shelf. He wants to divid them equally among 4 shelves there are 37 action figures Brody says he will have2 left over find and correct his mistake

To do this we will divide. lets do it:-

37 ÷ 4 = 9.25

So, now we will multiply. 

9 × 4 = 36.

Next subtract.

37 - 36 = 1

So, Brody will have 1 action figure left over with each of the 4 shelves having 9 action figures each. 

Hope I helped ya!!

The figure gets smaller. Think of scale factor of enlargement as a multiple of size. If the SF is 2, you double the size of the object. So if the SF is 1/2, then you halve the size of the object.

What is the area of the figure?

The area formula for rectangles is lxw. To solve, I would divide the figure up into 3 rectangles- top,middle and bottom, then find the areas and add them together.

Top: 4x13=52 cm^2
Middle: 5x8=40 cm^2
Bottom: 21x10=210 cm^2

(5 is the width of the middle piece. You get it from subtracting. 21-8-8=5. 13 is the width of the top piece. 5+8=13)

52+40+210
=302 cm^2
So your answer is 302 square centimetres.

PLEASE HELP ME! In the figure shown, the measure of angle 6 is 141º. What is the measure of angle 5?

So lets look at the information we have:-

angle 6 = 141°
angle 5 = ? 

Angle 5 and angle 6 TOGETHER form a supplementary angle. A supplementary angle is equal to 180°. So, to find out angle 5 we will subtract 180° by angle 6 (141°). And then we will check our work. Lets do it:-

180° - 141° = 39°
Angle 5 = 39°

CHECK OUR WORK:-

39° + 141° = 180°
We were RIGHT!!! 

So, angle 5 measures 39°.

Geometry homework help??? Pooters and Dooters were walking across a bridge one day, minding their own business. They knew that a train was due to come across that bridge soon, but they thought they could make it. It was a nice sunny day, and there was a great view from the bridge, so they walked very slowly, enjoying the view and savoring the warmth of the spring day. They were one-third of the way across the bridge, when the sound of a train whistle brought them instantly back to reality. Looking back over their shoulders, they saw a huge locomotive pulling tons of boxcars coming directly at them at 24 miles per hour! Using all their powers of mathematical reasoning, Pooters and Dooters immediately figured that they could run directly ahead and get to the far edge of the bridge at the exact same instant as the train. But they also knew that they could run back toward the train and get to the near end of the bridge just as the train got there. Basically, they knew they were dead meat. How fast do Pooters and Dooters run?

Ah hah !  NOW I see it.  Thanks to BellBell for a good link.

My first impression is a dog bone standing up on one end.

You're talking about the area of the figure, so I'll think that over
before I look at the choices.

I see:

-- 2 semi-circles = 1 whole circle.
and
-- (1 rectangle) minus (a trapezoid).

Now I'll look through the choices.

A).  No good.  The trapezoid is cut OUT of the figure,
and shouldn't be added into it.

B).  Oh ! Yes !  I didn't look at it that way at first, but
I can see how that works.  'B' is good.

C). and D).  Yes.  This was my description above.

So 'A' is the method that's wrong.

The ratio of water to orange juice to cranberry juice in a punch bowl should be 2:5:3. If Clementine has 24 ounces of cranberry juice and wants to strictly follow the recommened ratio, how many ounces of punch can she make? (Assume she has an unlimited suplly of orange juice and water.) Explain how you would figure this out.

Water= 2
Orange juice= 5
Cranberry Juice= 3

Since the cranberry juice is 24 ounces, and 3 ounces in the other ratio, we know that 3*8=24, so we would multiply all of the others by 8. 

Cranberry juice: 3*8=24
Orange juice: 5*8= 40
Water: 2*8=16

So our ratio would be 16:40:24

In this figure, AFC=EFC. Which statement must be true? a) AD Perpendicular EB b) EB Perpendicular CA c) AD Perpendicular CE d) CF Perpendicular AE

Answer:

The statement is true is  CF Perpendicular AE .

Option (d) is correct.

Step-by-step explanation:

As given

∠AFC = ∠EFC

Let us assume that the measure of ∠AFC be x.

Thus

∠AFC = ∠EFC = x

As

∠AFC + ∠EFC =  180°  (By Linear pair property)

x + x = 180°

2x = 180°

x = \frac{180}{2}

x = 90°

Thus

∠AFC = ∠EFC = 90°

Therefore CF is perpendicular to AE .

Option (d) is correct.

My question is this, do I have the right equation to figure this problem? Boys 5(x) =33 Girls = x x+5(x)=33 6x =33 6/6. 33/6 x=5.5 this is where I'm lost. What do I do next? Or, do I have it all wrong?

There are 33 students in the Chess Clubs. There are 5 more boys than girls in the club.
Now, the equation will be like this
girls = x
boys = x + 5
x + 5x = 33
let’s solve for X
=>  x + (x + 5) = 33
=> 2x + 5 = 33
=> 2x = 33 - 5
=> 2x /2 = 28 / 2
=> x = 14
Thus the number are:
girls = 14
boys = 14 + 5 = 19
=> 19 + 14 = 33

Answer: a. 12.66 cm

Step-by-step explanation:

Given value: 12.655 cm

Here in the given value there area five significant figures.

If we need to round the value to four significant figures then we need to round the given value to the nearest hundredth.

Enter the answer to the problem below, using the correct number or significan figures 100*3.25

100 * 3.25 = 325

In multiplying numbers with decimal points, you have to do the following.

1) remove the decimals and consider the number as a whole number
   from 3.25 to 325.
2) Consider the 100 in the equation. We know that whatever number is multiplied by 0 is always 0. So, we only consider 1.

   3  2  5
           1  0  0
------------------
  3  2  5  0  0

In big numbers we always start multiplying the number from the right side, which is 5. Since, the multiplicand is 1. Whatever number multiplied by 1 is always equal to that number.

325 * 1 = 325; add the two 0s attached to 1. = From 325 to 32500.

Now, 32500 is the product when we multiply 325 by 100. But, remember 325 is not really a whole number, it has decimals.

3.25 == count the number of places after the decimal. in this case, there are two places.

In the product 32500 == count the number of places from the last digit to know the placement of the decimals. There must be 2 places after the decimal.

FROM 32500 TO 325.00 = Since we can disregard the 00 after the decimal numbers.

100 * 3.25 = 325
