If CB=2x+5 and DE=10, find the value of x
Step-by-step explanation:
see the attachment......
Answer:
[tex]x=4[/tex]
Step-by-step explanation:
We are given that:
[tex]CB=2x+5[/tex]
And that DE = 10. We want to determine the value of x.
Note that CB is the sum of CD and DB. In other words:
[tex]CB=CD+DB[/tex]
Similarly, DE is the sum of DB and BE. Thus:
[tex]DE=DB+BE[/tex]
From the second equation, we can subtract BE from both sides:
[tex]DE-BE=DB[/tex]
Substitute this into the first equation:
[tex]CB=CD+(DE-BE)[/tex]
We are given that CB is 2x + 5 and DE is 10.
From the diagram, we can also see that CD is 3x - 1 and BE is 8.
Substitute:
[tex](2x+5)=(3x-1)+((10)-(8))[/tex]
Solve for x:
[tex]\displaystyle \begin{aligned}(2x+5) & = (3x-1) + (2) \\ \\ 2x + 5 & = 3x + 1 \\ \\ -x + 5 & = 1 \\ \\ - x & = -4 \\ \\ x & = 4 \end{aligned}[/tex]
In conclusion, the value of x is 4.

Answer:
So the number of flowers per vase
= 8 flowers per vase
Remainder= one flower
Step-by-step explanation:
Darren picked 25 flowers that he plans to divide evenly into 3 vases.
Number of Flowers touse per vase

does a regular pentagon tessellate and why
Answer:
No, a regular pentagon does not tessellate.
In a tessellation, all the angles at a point have to add to 360 degrees, as this means there is no overlap, nor are there gaps. To find the interior angle sum of a pentagon, we use the following formula:
(n-2)*180 (where n is the number of sides)
We plug in the number of sides (5) and get:
Angle sum = (5–2)*180
Angle sum = 3*180
Angle sum = 540
Regular pentagons have equal sides and equal angles, so to find the size of the interior angle of a pentagon, we divide the angle sum by 5 and get 108 degrees for every angle.
As I said before, the angles at a point need to add up to 360, so we need to know if 108 divides evenly into 360. If it does, the shape tessellates, and, if it doesn’t, the shape does not.
360/108 = 3.33333…
This means that a regular pentagon does not tessellate.

Bessy has 6 times as much money as Bob, but
when each earns $6, Bessy will have 3 times as
much money as Bob. How much does each have before
and after earning the $6?
Answer:
Before: Bob, $4; Bessy, $24After: Bob, $10; Bessy, $30Step-by-step explanation:
Let x represent the amount of money Bob starts with. Then Bessy starts with 6x. After they have each earned $6, the relationship of their amounts is ...
(6x +6) = 3(x +6)
6x +6 = 3x +18
3x = 12
x = 4
Bob starts with $4; Bessy with $24.
After earning $6, Bob has $10; Bessy has $30.
Two separate samples receive two different treatments. The first sample has n = 9 with SS = 710, and the second has n = 6 with SS = 460. Compute the pooled variance for the two samples.
Answer:
The pooled variance for the two samples is 90
Step-by-step explanation:
Here in this question, we are interested in computing the pooled variance for the two given samples.
From the question;
n1 = 9
ss1 = 710
n2 = 6
ss2 = 460
The pooled variance can be calculated using a mathematical formula as shown below;
S^2 =( ss1 + ss2)/(n1 + n2 -2)
where S^2 refers to the pooled variance of both samples.
Plugging the values into the equation, we have ;
S^2 = (710 + 460)/9 + 6 -2 = 1170/13 = 90

The triangular figures shown below are constructed with toothpicks. The pattern shows what happens with 1 triangle, with 2 triangles, and with 3 triangles. Describe a possible pattern. Assuming the pattern continues, answer the following questions. How many toothpicks would be needed for the 10th figure? How many toothpicks are needed for the nth figure? In which figure are exactly 102 toothpicks used?
Answer:
(a) 51
(b) [tex]T_{n}=a+(n-1)d[/tex]
(c) 20th figure
Step-by-step explanation:
The diagram is attached below.
The first triangle is formed using 6 toothpicks.
The second triangle is formed using 11 toothpicks.
The third triangle is formed using 16 toothpicks.
So, there is an increases of 5 toothpicks every time.
We can say that the number of toothpicks used to form n triangles are following an arithmetic progression with the first term as 6 and the common difference as 5.
The nth term will be:
[tex]T_{n}=a+(n-1)d[/tex]
(a)
Compute the number of toothpicks required for the 10th figure as follows:
[tex]T_{n}=a+(n-1)d[/tex]
[tex]T_{10}=6+(10-1)\times5[/tex]
[tex]=6+(9\times5)\\=6+45\\=51[/tex]
Thus, the number of toothpicks required for the 10th figure is 51.
(b)
Compute the number of toothpicks required for the nth figure as follows:
[tex]T_{n}=a+(n-1)d[/tex]
(c)
Compute the value of n for [tex]T_{n}=102[/tex] as follows:
[tex]T_{n}=102[/tex]
[tex]a+(n-1)d=102\\\\[/tex]
[tex]6+(n-1)\times 5=102[/tex]
[tex]5(n-1)=96[/tex]
[tex]n-1=19.2[/tex]
[tex]n=20.2\\n\approx 20[/tex]
Thus, the 20th figure will require exactly 102 toothpicks.

Jerome and eric start their hike at point a and follow the trail in the counterclockwise direction. they stop at point w to eat lunch. how manu total miles have jerome and erick hicked when they stop for lunch
Answer:
12.5 feet
Step-by-step explanation:
The distance in a coordinate geometry is calculated using: [tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]. Jerome and Eric have hiked 12.4 miles when they stopped to eat.
To do this, we make use of distance formula
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
From the figure, we have the following points:
[tex]A = (4,4)[/tex]
The other points between A and W in counterclockwise are:
[tex]B=(6,2)[/tex]
[tex]C = (8,2)[/tex]
[tex]D = (8,4)[/tex]
[tex]E = (10,6)[/tex]
[tex]W = (8,8)[/tex]
Distance AB is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
[tex]AB = \sqrt{(4 - 6)^2 + (4 -2)^2} =\sqrt{8} =2.8[/tex]
Distance BC is
[tex]BC = \sqrt{(6 - 8)^2 + (2 -2)^2} =\sqrt{4} =2[/tex]
Distance CD is
[tex]CD = \sqrt{(8 - 8)^2 + (2 -4)^2} =\sqrt{4} =2[/tex]
Distance DE is :
[tex]DE = \sqrt{(8 - 10)^2 + (4 -6)^2} =\sqrt{8} =2.8[/tex]
Distance EW is:
[tex]EW = \sqrt{(10-8)^2 + (6 -8)^2} =\sqrt{8} =2.8[/tex]
So, distance AW is:
[tex]AW = AB + BC + CD + DE + EW[/tex]
[tex]AW = 2.8 + 2+ 2 + 2.8 +2.8[/tex]
[tex]AW = 12.4[/tex]

Angle Relationship:
Angle m=
Angle k=
Angle h=
Angle p=
Angle q=
Angle f=
Angle g=
Angle s=
Angle r=
Angle u=
Angle v=
Answer:
m = 123°
k = 57°
h = 123°
p = 99°
q = 81°
f = 99°
g = 81°
s = 42°
r = 57°
u = 57°
v = 123°
Step-by-step explanation:
Using basic angle relationships, we should be able to tell these angles easily.
If the 57° is supplementary to m, then m will be [tex]180 - 57 = 123[/tex] degrees.
k is also supplementary to m, so k is [tex]180-123=57[/tex] degrees - we also know this because it is an alternate interior angle to the other 57°.
h is an alternate interior angle to m, so h is the measure of m : 123°.
q is the same measure as the 81° angle, since they are corresponding angles. q is also 81°.
p is supplementary to q, so p is [tex]180-81=99[/tex] degrees.
f is an alternate interior angle to p, so f is also 99°.
g is also an alternate interior angle to q, so g is 81°.
The measure of s will be [tex]180-k-g[/tex] since all 3 sides of a triangle add up to 180°: so [tex]180-57-81=42[/tex] degrees.
r will be supplementary to the 81° angle and s, 42, so r is [tex]180 - 81 - 42=57[/tex] degrees.
u is an alternate interior angle to r, so u is also 57 degrees.
v is supplementary to u, so v will be [tex]180-57=123[/tex] degrees.

How far have I travelled if I biked at 10mph for hhrs, I walked at 3mph for twice as long as I biked, and ran at 10mph for one quarter as long as I walked? Translate into expression, I will award brainiest!
Answer:
21h
Step-by-step explanation:
we know that
Speed = distance / time, and as such
distance = speed * time
From the question, we are given that ...
He biked for h hrs -> b
He walked for 2 * b = 2h -> w
He ran for (1/4)(w) = 1/4 * 2h = 1/2 h -> r
The total distance traveled will then be
total distance = distance biked + distance walked + distance ran
recall that we stated that
d = s * t, now we'd apply that here
distance biked = 10 * h = 10h
distance walked = 3 * 2h = 6h
distance ran = 10 * 1/2h = 5h
total distance = 10h + 6h + 5h
Total distance = 21h

Bob decided to go to college, the cost of going to school will be $4,474 per semester, (there are 2 semesters per year) plus $389 per semester for books. His degree will take 4 years. If he wants to pay off his investment in 10 years or less what is the minimum increase in yearly salary he would need to earn upon finishing his degree.
Answer:
Step-by-step explanation:
1 semester = 4474
8 semester = 8* 4474 35792
1 semester books = 389
8 semester books = 8* 389 3112
Total 38904
If he is going to pay this off in 10 years, he would have to have an increase of 3890.40 (after all income taxes) to pay it off. Fewer years would mean dividing by the number of years.
So for 8 years for example, he would need 4863 every year.
That number is obtained by dividing 38904 / 8
In 6 years he would need
38904/6 = 6484 extra dollars.
