m<DBE +64.5°= 90°
m<DBE = 90°-64.5°
m<DBE = 25.5°

In how many ways can you make a tower using three blue blocks and two red blocks? Make a “tree” and draw a picture of the towers.
Answers
Answer:
For tree see picture but instead of BG replace all values with RRBBB and see the notes above how to roate the colours instead of the shape roation below just do transition (0,0)(1,0) (1,1).
Then 13 colours minimum change.
This will be 3 + 5 + 4 each colour change = 12 each colour change. instead of doing the 56 each colour rotation below.
Step-by-step explanation:
make 4 bits of paper and label each side -1 and 1 and central 0
above central point vertically label 1 and -1 for transition.
Then change just top one 4x = 4 more
Do the same with 2nd from top = 8 more to include top changing 4x again.
Do the same with 2nd from bottom = 12 more
Do the same with bottom = 16 more.
4+8+12+16 =40
Then repeat the process on side for blocks and we can double up
40+40 = 80.
When drawing tree clearly state columns
Top two are red only change
Top of tree will read in order so where ever you see capital R you will know its a new column for the tree and fill in when you understand the 254 transitions of a 5 column tree. Then change B + R accordingly when you get to row 6. Here you just start changing blue back to the top after row 5
Columns go down and rows go across its a new row you will need
approx 5-6 rows each colour change.
For the ones started for you below its just transition and colour stays where it is.
R x RT 45d RT (1,0) 45 RT (1,1) 45 RT (1,0)
R x R x
B x B x
B x B x
B x B x
'x' = RED Normal as you keep 0 zero central on all 4 bricks and work with top row as explained below.
Top RED brick you have to Right side place transition on every 2nd column for each colour and thenyou should find a pattern if youve numbered your papers or brcks to just see how it works. (hanging out one side call this 'off set' or call it T for transition (1.0)
RED Central 'diagonal' call it '45 degree rotate'
E ABCD RED Normal edge transition its edge so it hangs out
E ABCD RED On edge 45 degree diagonal its edge so it hangs out
2nd only change
S ABCD 1st red normal 2nd red Right side place rotate
S ABCD 1st red right side rotate 2nd red 45 degree rotate
S ABCD 1st red right side rotate 2nd central place 45 degree rotate
S ABCD 1st red right side rotate 2nd edge Normal edge transition
S ABCD 1st red right side rotate 2nd 45 degree its edge diagonal
2nd is repeated by changing 1st 4x more in bold. see what is now missing for 1st red. and copy the 2nd changes to 1st all whilst rotaing 2nd again in change .
Copy paste the work
Then apply this to 3 + 4 + 5th brick.
As the above shows 10 and when you finish 2nd and 1st it will be 14 total
Then 3 will be 14 again
and 4th brick will be 14 again
and 5th brick will be 14 again
making the transitions and rotations where all bricks in same level placement
14 x 4 = 56 transitions/rotations
Then repeat again for 1 blue at the top change
Then repeat again for 2 blue at the top for change
Then repeat again for 2 blue in the top middle
Then repeat again for 2 blue in the bottom middle
You can label tree
RR = Red rotation
BR = Blue rotation
RRE= Red rotation edge
BRE = Blue rotation
and colour code blue and red pens.
You can label transitions
RT = red transition (1,0)
RT = red transition (1,1) for central
and same for blue etc..
The end result will be 56 x 4 = 224 diagram tree

5 more than a number y is negative 2
write the word sentence in a equation.
Answers
Answer:
5 + y = -2
Step-by-step explanation:
To get 5 more than a number, you need to add 5 to the number. Then "5 more than y" is "5+y" or "y+5".
In math, "is" means "is equal to."
5 more than a number y is negative 2 means ...
5+y = -2
Answer:
[tex]5 + y = ( - 2)[/tex]
Step-by-step explanation:
Five more than a number means,
[tex]5 + y \: \: \: \: or \: \: \: \: y + 5[/tex]
is means equal to.
[tex] = [/tex]
is negative 2
[tex] = - 2[/tex]

Let f(x) = 3x - 5. g(x) = f(x + 4) and h(x) = g(–3x). What are the slope and y-intercept of the graph of function h?
Answers
Answer:
Slope is - 9, y-intercept is 7.
Step-by-step explanation:
f(x) = 3x - 5
g(x) = f(x+4) = 3(x+4) - 5= 3x + 12 - 5 = 3x + 7
h(x) = 3( - 3x) + 7 = - 9x + 7
h(x) = - 9x + 7
Slope of h(x) is - 9, y-intercept is 7.

Samantha is solving the following system of equations using the method of substitution: 3x + 2y = 11 - x + y = 3 The following are Samantha's first two steps. y= x + 3 3x + 2(x+3) =11 HINT: Solve the bottom equation for x and then plug that value back into the first equation to solve for y. Arrange the steps below to match the order you used to do this.

C:[tex]y\geq \frac{1}{2}x +2[/tex]
Answers
Answer:
According to the numbers provided, the sequence is:
5, 6, 1, 4, 7, 3, 2
Solution of the two lines intersecting in the graph is answer B
The inequality that represents the graph is that of answer A
Step-by-step explanation:
First problem:
This is the sequence to solve for "x" once the substitution was made;
[tex]3x +2\,(x+3)=11\\3x+2x+6=11\\5x+6=11\\5x=11-6\\5x=5\\x=1\\[/tex]
Now that we know x, we use its value (1) in the substitution equation in order to find "y" and complete the ordered pair:
[tex]y=x+3\\y=1+3\\y=4[/tex]
Then the solution pair (x, y) is: (1, 4)
Therefore, according to the numbers provided in the list of possible steps, the order is:
5, 6, 1, 4, 7, 3, 2
Second problem:
The solution to the system is where the two lines two lines intersect: "the point -1.5 on the x axis. Notice that -1.5 can be written in fraction form as -3/2, this is the x-coordinate of the intersection point. The y-coordinate is y-0 since the point is on the x-axis. Therefore the point is (-3/2, 0) which is given by answer B).
Third problem: The boundary line seems to go through the points: (-4, -10) and (0, -2), so we can calculate the slope via the equation:
[tex]slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{-2-(-10)}{0-(-4)}\\slope=\frac{8}{4}\\slope=2[/tex]
since the line's y-intercept is (0, -2), then the equation of the boundary line in slope-intercept is:
[tex]y=2x-2[/tex]
Since the shaded region includes the boundary line and the zone above it (with y-values larger than or equal to those point in the line), we can say that the inequality that represents this graph is:
[tex]y\geq 2x-2[/tex]

The real distance between the ship and the base is 35 km and the measure of the bearing of B from S is 70 degrees.
How to find the scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
The diagram shows the position of the ship(S) and the marine base(B). The image of the ship is attached below.
a) Real distance between the ship and the baseWhen the distance of the attached image from ship and the base is measured by rules. It comes out 3.5 cm.
The scale of the diagram is 1 cm, represents 10 km. Thus, the real distance is,
[tex]BS=\dfrac{10}{1}\times3.5\\BS=35\rm\; km[/tex]
With the help of compass, the bearing angle of B from S is measured as,
[tex]\angle BSN=70^o[/tex]
Thus, the real distance between the ship and the base is 35 km and the measure of the bearing of B from S is 70 degrees.
