Answer 1

Answer:

$6.16

Step-by-step explanation:

$12.80*3/4=$9.60

$9.60+$12.80=$22.40

$9.28*3/4=$6.96

$6.96+$9.28=$16.24

$22.40-$16.24=$6.16

Hope this helps!

Answer 2
1/4=3.20
1/4•3= 9.60
12.80+9.60=22.40
9.28/4=2.32
2.32•3=6.96
9.28+6.96=16.24
22.40-6.96=15.44

Answers

Answer:

\(\sqrt{18.04}\)

Step-by-step explanation:

The wording is a bit confusing, but i beleive it basically means that we're trying to find the length on a leg of a triangle with a leg length of 3 and a hypotenuse of 5.2

if we write this out as an equation, it gives us:

\(5.2^{2}-3^{2}\)

If we then simplify this, we get 27.04 - 9, which then simplifies to 18.04.

We then need to get the square root of this number to get the answer, thus the answer is \(\sqrt{18.04}\)

Mr. Paulsen challenges Olivia and Angelica to move figure ABCDE onto figure A"B"C"D"E" using a series of two different transformations. They give two different answers.

Answer the questions to investigate ways to transform ABCDE.

1. Olivia finds a combination of two different transformations that moves ABCDE onto A"B"C"D"E". What is one way she might have done this?

2. Angelica reflects ABCDE over the y-axis and translates it up 8 units. Does her transformed figure match A"B"C"D"E"? If not, describe how her transformed figure compares to A"B"C"D"E".

3. Michael says he can move ABCDE onto A"B"C"D"E" with one transformation by translating ABCDE diagonally so that it moves 8 units up and 10 units right. Is he correct? Explain why or why not.

Mr. Paulsen challenges Olivia and Angelica to move figure ABCDE onto figure A"B"C"D"E" using a series

Answers

Problem 1

One method Olivia could have used is to reflect over the x axis and then translate 10 units to the right.

Let's apply these set of steps to point C.

C = (-2,-4)

C' = (-2,4) after reflecting over the x axis; y coordinate flips in sign

C'' = (8,4) after shifting to the right 10 units; add 10 to the x coordinate

Point C(-2,-4) moves to C''(8,4) which is shown in the diagram. I'll let you check the other four points.

-----------

Another method Olivia could have used is to shift to the right 10 units first, then reflect over the x axis. In this case, the order doesn't matter. Though for some other combinations of transformations, order does matter.

============================================================

Problem 2

Reflecting over the y axis will have the point (x,y) turn into (-x,y). Only the x coordinate changes, and we flip the sign here. The y coordinate stays the same.

A point like C(-2,-4) becomes C'(2,-4) after the y axis reflection. Shifting up 8 units means we add 8 to the y coordinate to arrive at C''(2,4) but this does not match what the diagram shows. Therefore, Angelica's method is incorrect.

You should find other inconsistencies for the other four points as well.

============================================================

Problem 3

Michael's method isn't correct either. He does not apply an x axis reflection and instead relies entirely on translations to move ABCDE to A''B''C''D''E''

At a quick glance, it looks like Michael may be correct. But upon a much closer look, you'll see that things don't line up perfectly.

Instead of point C, we'll pick on point D this time.

D is located at (-6,-2). If we shift up 8 units, then we add 8 to the y coordinate to get to D'(-6,6). Then add 10 to the x coordinate to shift 10 units to the right. This leads us to D''(4,6).

However, the diagram shows D'' is actually at (4,2)

I'll let you check the other points. You should find that only points C and E go to the correct locations, but the other points do not. Again, this is because Michael did not apply an x axis reflection. His figure of A''B''C''D''E'' is upside down compared to what it should be.

============================================================

To summarize, the methods described in problem 1 are the correct way to get ABCDE to move to A''B''C''D''E''. If Olivia followed either of those two methods, then she is correct. Both Angelica and Michael have incorrect methods.

How many sides do 4 nonagons and 4 triangles have in all?

Answers

Answer:

Sorry for the late answer!

Step-by-step explanation:

A nonagon has 9 sides so 9 * 4 = 36

and a triangle has 3 sides so 3 * 4 = 12

add them together (36 + 12 = 48)

Your final answer will be 12, Hope this helps, and have a great day!

48

Nonagons have 9 sides.
If there are 4 nonagons, then you will multiply 9 and 4.
9x4= 36

Triangles have 3 sides.
If there are 4 triangles, then you will multiply 3 and 4.
3x4= 12

In total, you will need to add them (12+36)

12+36= 48

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answers

Answer:

15

Step-by-step explanation:

How to calculate a triangle :

(b*h)/2

(4*5)/2=10!

A similar triangle should have a ratio of base and height 4:5

4*5=20/2=10 (Not 90)

8*10=80/2=40(Not 90)

12*15=180/2=90!

So 12 is the base and 15 is the height. :)

Answer:

10 = (1/2)4h  →   20 = 4h     →  h = 5  So the base of the first triange is 4m and the height is 5m Note that the area of our new triangle is 9 times the area of the old then each dimension will be sqrt(9)  = 3 times as much as the old so  The base of the new triangle will be 4*3  = 12m  And the height will be  5 * 3  = 15m  Proof:  A = (1/2)(12)(15)  = (1/2) * 180  = 90 m^2
