Compute and compare the side lengths of the two figures. Does this support an argument claiming that they are congruent? What else must be true to say two polygons are congruent?

The side lengths of the two figures can be calculated with the distance formula:

 √ (x1 - x2)² + (y1 - y2)²        

AB = √13  

BC = √13      

CD = √13    

DA = √13  

A'B' = √13      

B'C' = √13      

C'D' = √13      

D'A' = √13

They are all the same lengths. This supports an argument claiming that they are congruent because if the sides are congruent, then the two polygons are congruent.

Something else that must be true to say that two polygons are congruent is that the angles have equal measures.

Hope this helps! :)

If the measure of angle 4 is 132°, what is the measure of angle 7?

Angles 1, 3, 5, 7, 9 and 11 are corresponding while angles 2, 4, 6, 8, 10 and 12 are corresponding
angles 8 and 7 are supplementary
since 4 and 8 are corresponding, angle 4 is 132° so angle 8 would also be 132°
180-132=48

Given points A(4,5) and B(-4,11). Find the distance AB to the nearest tenth.

If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number. Why?

Dividing is the action of slimming a number down to a smaller size. When you divide a whole number by a decimal less than 1 the quotient is greater than the whole number because the that is how many times the quotient is a part of the whole number. For instance, you divide 100 by 4, you will get a quotient of 25. There are 4 parts of 25 to be equal to 100.

The lengths of three sides of a triangle are given. Determine whether each triangle is a right triangle. 1. 14 m, 5 m, 4 m 2. 3 in., 4 in., 5 in. Are these right triangles?

In a right triangle, the hypotenuse is always the longest side.  Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides.  For the first "triangle" above: does 14 ^{2} =5 ^{2} +4 ^{2} ?  Let's check.  196 = 25 + 16 so does 196 = 41?  Obviously not.  So that is not a right triangle.  Let's check the second one the same way.  Does 5 ^{2} =3 ^{2} +4 ^{2} ?  25 = 9 + 16.  Does 25 = 25?  Of course it does!  So 1 is not a right triangle, but 2 is!

Jorge needs to ship a thin metal rod to a metalworking shop. The only boxes available for shipping are 7-inch cubes. To the nearest inch, what is the length of the longest metal rod that can be sent? 11 inches 12 inches 13 inches 14 inches

Answer:

The length of the longest metal rod that can be sent is 12 inches.

Step-by-step explanation:

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

D=\sqrt{x^{2}+x^{2}+x^{2} }

= \sqrt{3} x

Here, x is 7 inches.

So, Diagonal is = \sqrt{3} \times7

= 1.732\times7=12.12 inches.

Rounding this to nearest whole number we get 12.

So, the length of the longest metal rod that can be sent is 12 inches.

So when you turn it into a decimal it has a correct place value say if you have 0.70 as a fraction it would be 70/100 because the fraction is telling you it's hundredths one tip is look at the decimal pretend it's always a 1 then in front of the decimal is all zeros and that is your denominator.

QUESTION POSTED AT 28/03/2020 - 12:43 PM

A box of 6 coins (penny, nickel, dime or quarter) worth $0.67 is shaken. What is the probability that a nickel is drawn first and then a quarter? Assume no replacement and that all coins are equally likely.

Answer:

There is a 6.67% probability that a nickel is drawn first and then a quarter.

Step-by-step explanation:

There are 6 coins. The sum of their values is $0.67. We need to find how many of each coin are there.

A penny is worth 1 cent.

A nickel is worth 5 cents.

A dime is worth 10 cents.

A quarter is worth 25 cents.

To get to 67 cents, we need:

Two pennies, a nickel, a dime and two quarters.

So:

What is the probability that a nickel is drawn first and then a quarter? Assume no replacement and that all coins are equally likely.

Initially there are 6 coins, of which 1 is a nickel. So the probability that the nickel is drawn is:

P_{1} = \frac{1}{6}

There are no replacements, so now there are 5 coins, of which 2 are quarters. So the probability that a quarter is drawn is:

P_{2} = \frac{2}{5}.

The probability that a nickel is drawn first and then a quarter is:

P = P_{1}*P_{2} = \frac{1}{6}{2}{5} = \frac{1}{15} = 0.0667

There is a 6.67% probability that a nickel is drawn first and then a quarter.
