Answer:
21–24 and 28 are correctly marked
25: NEI; 26: ASA or LA; 27: SSS
Step-by-step explanation:
25: At least one side is required for showing congruence. In figure 25, only angles are shown congruent, so there is not enough information.
__
26: Two angles and the side between them are marked congruent. These triangles can be declared congruent by ASA. Considering they are right triangles, one could also invoke LA as the appropriate theorem.
__
27: The unmarked sides of the two outside triangles can be shown to be congruent by virtue of the fact they are opposite congruent angles in the middle triangle. Hence all three sides can be shown congruent for those outside triangles, and the SSS postulate can be invoked.

Explanation:
Choice A is true assuming we have [tex]a_n = (-1)^n*b_n[/tex]
In this case, [tex]a_n = (-1)^n*\frac{1}{\sqrt{n}}[/tex] and [tex]b_n = \frac{1}{\sqrt{n}}[/tex]
--------
Choice B is false. See choice A above.
--------
Choice C is true. The sequence [tex]\{b_n\}[/tex] is decreasing. As n gets larger, [tex]b_n[/tex] gets smaller. This is because the denominator is growing larger with the numerator held constant.
--------
Choice D is false. This contradicts choice C.
--------
Choice E is true since the denominator is growing forever
This is similar to [tex]\displaystyle \lim_{n \to \infty} \frac{1}{n} = 0[/tex]
--------
Choice F is true due to choices C and E being true.
--------
Choice G is false because it contradicts choice F.
find the measures of arc FBD
Answers
Answer:
Option (4)
Step-by-step explanation:
[tex]m(\widehat{FC})[/tex] = 180° [FC is the diameter]
[tex]m(\widehat{FC})=m(\widehat{FB})+m(\widehat{BC})[/tex]
180° = 125° + [tex]m(\widehat{BC})[/tex]
[tex]m(\widehat{BC})=180-125[/tex] = 55°
[tex]m(\widehat{FBD})=360-m(\widehat{FED})[/tex]
[tex]=360-[m(\widehat{FE})+m(\widehat{ED})][/tex]
[tex]=360-[m(\widehat{BC})+m(\widehat{ED})][/tex] [Since [tex]m(\widehat{FE})=m(\widehat{BC})[/tex] arcs created by vertical angles]
[tex]=360-(55+56)[/tex]
= 249°
Therefore, Option (4) will be the answer.

Ms. Banks walks at about 3 feet per second. How many miles per day could she travel.if she walked without
taking a break?
1
0.81 miles per day
16.36 miles per day
49.09 miles per day
2.04 miles per day
Answers
Answer:
49.09 miles per day
Step-by-step explanation:
There are 5,280 feet in one mile.
There are 60 seconds in one minute.
3 * 60 = 180 feet per minute
There are 60 minutes in one hour.
180 * 60 = 10,800 feet in one hour.
There are 24 hours in one day.
10,800 * 24 = 259,200 feet per day.
Divide to find how many miles she can walk.
259,200 / 5,280 = 49.09 miles

what are the measures of angles a,b,c ?
Answers
Answer:
a=30 , b=60, c=105
Step-by-step explanation:
a=30 [Being vertically opposite angle]
Now,
a+b+90=180 [Being the sum of interior angles of a triangle]
or, 30+b+90=180
or, b+120=180
or, b=180-120
so, b= 60
Again,
c+75= 180 [Being linear pair]
or, c=180-75
so, c= 105

The increase however has a percentage of .18%
To check your work you would do .18 x 1234 = 222.12 ( round to the nearest whole number so it would just be 222) then add 1234+ 222 = 1456!

Answer:
a. 1.88495559215 radians
b. 5.23598775598 radians
c. 1.57079632679 radians
d. 4.93678845564 radians
Step-by-step explanation:
You want the coefficient of pi to be between 0 and 2. That is, you want its value modulo 2--the remainder from division by 2.
a. 13/5 = 2.6; 2.6 mod 2 = 0.6. 0.6π ≈ 1.88495559215 (as you know)
b. -13/3 = -4 1/3; -4 1/3 mod 2 = 1 2/3*. 5/3π ≈ 5.23598775598
c. 57/2 = 28.5; 28.5 mod 2 = 0.5. 0.5π ≈ 1.57079632679
d. 11/7 = 1 4/7. 11/7π ≈ 4.93678845564
All angles are in radians.

four pumpkins weigh 26 pounds altogether. Pumkin one weighs four less than three times the weight of Pumkin threee. Pumkin four weighs twice as much as pumkin One. Pumpkin Two weighs five more pounds than Pumkin three. What does each pumpkin weigh
Answers
Answer:
5, 8, 3, 10 lbs.
Step-by-step explanation:
We can solve this using a system of equations! We will call pumpkins [tex]a, b, c, d[/tex].
Our equations are thus:
[tex]a + b + c + d = 26[/tex]
[tex]a = 3c - 4[/tex]
[tex]d = 2a[/tex]
[tex]b = c + 5[/tex]
So now we just need to solve this system of equations.
We can start by solving for the value of pumpkin [tex]c[/tex] and go from there. So first we substitute some equations around.
First we write out pumpkin [tex]d[/tex] in terms of [tex]a[/tex].
[tex]d = 2a = 2(3c - 4) = 6c - 8[/tex]
And now we put the three equations into the first equation:
[tex]a + b + c + d = 26\\(3c-4)+(c+5)+(c)+(6c-8)=26[/tex]
Then we simplify to get:
[tex]11 c - 7 = 26[/tex]
[tex]11c = 33\\c = 3[/tex]
So we know pumpkin [tex]c[/tex] weighs 3 pounds.
Then we use the equations from before to get the value of the other pumpkins:
[tex]a = 3c-4 = (3*3)-4=9-4=5\\d = 2a = 2*5=10\\b = c + 5 = 3 + 5 = 8[/tex]
And we can check our results by putting into first equation:
[tex]5+8+3+10=26[/tex]
So it works out!
Thus our pumpkins weigh 5, 8, 3, 10 lbs each.
Graph the image of the given triangle after the transformation that has the rule (x, y)→(x−5, y+6). Select the Polygon tool. Then, click the points of the triangle vertices to create the triangle by connecting the sides.
Answers
Answer:
Step-by-step explanation:
Transformation involves changing the position of a shape in the coordinate.
See attachment for the image of the triangle
Assume the triangle is triangle ABC.
The coordinates of ABC are:
[tex]\mathbf{A = (-1,-4)}[/tex]
[tex]\mathbf{B = (-2,-7)}[/tex]
[tex]\mathbf{C = (5,-6)}[/tex]
The transformation rule is given as:
[tex]\mathbf{(x,y) \to (x -5,y+6)}[/tex]
So, we have:
[tex]\mathbf{A' = (-1 -5,-4+6)}[/tex]
[tex]\mathbf{A' = (-6,2)}[/tex]
[tex]\mathbf{B' = (-2 -5,-7+6)}[/tex]
[tex]\mathbf{B' = (-7,-1)}[/tex]
[tex]\mathbf{C' = (5 -5,-6+6)}[/tex]
[tex]\mathbf{C' = (0,0)}[/tex]
So, the coordinates of the new triangle would be:
[tex]\mathbf{A' = (-6,2)}[/tex]
[tex]\mathbf{B' = (-7,-1)}[/tex]
[tex]\mathbf{C' = (0,0)}[/tex]

240 in a ratio of 3:5?
Answers
therefore,3x+5x=240
8x=240
x=30
so,3x=3×30=90
5x=5×30=150
so,we divide 240 in 90 and 150 to get ratio 3:5
The number who needs to be made into a ratio = 240
Total number of parts = 3 + 5
= 8 parts
Each part = 240 ÷ 8
= 30
Then three parts = 30 × 3 = 90
Five parts = 30 × 5 = 150
Then , the ratio will be = 90 : 150
Therefore , 240 in a ratio of 3 : 5 = 90 : 150 .

Step-by-step explanation:
Let the width be represented by w. We can then assume that the length is equivalent to 3w+4
So, we can set the equation 2(3w+4)+2(w). Simplify to 8w+8=64
Simplify the equation and solve for w, which is 7
Plug into the the length, which is 3w+4
Answer:
Length: 25 inches
Width: 7 inches
Step-by-step explanation:
Perimeter = 2L + 2W
Length: 3w + 4
Width: w
64 = 2(3w + 4) + 2w
64 = 6w + 8 + 2w
64 = 8w + 8
56 = 8w
w = 7
Length: 3(7) + 4 = 25
Width: 7
