Answer:
OctagonStep-by-step explanation:
An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees.
Because the octagon is regular, all of its sides and angles are congruent
Answer:
It's an octagon. So should be the first one with 8 points.

Answer:
7
Step-by-step explanation:
Circunference:
The circunference of a circle with diameter d is given by:
[tex]C = d\pi[/tex]
The diameter of a £1 coin is 22.5 mm.
Each mm has 0.1 cm, so the diameter, in cm, is of d = 2.25. Then
[tex]C = 2.25\pi = 7[/tex]
The circunference is of 7 centimeters.
A father and his son decide to sum their ages. The sum is equal to sixty years. Six years ago, the age of the father was five times the age of his son. Six years the son's age will be?
I will mark as brainlist plzzzzz
Solve the question I know the answer but i cannot solve it..
I can tell you that ans is 16.8 years but solve...
Answer:
20
Step-by-step explanation:
Let father's age be x
let son's age be y
x + y = 60 - (eq 1)
Six years ago,
(x - 6) = 5(y - 6) -(eq 2)
From (1)
x = 60-y
Therefore, 60-y - 6= 5y - 30
y = 14
in six years, y = 20

Sam Store orders 200 pens that list for $0.5 each, 150 pads that list for $0.7 each, and 100
pencils that list for $0.2 each. The single trade discount rate for the order is 15%. Find the net
price of the order and the amount of discount.
Answer:
Net price = $191.25
Discount Price = $33.75
Step-by-step explanation:
Cost of one pen = $0.50
Cost of 200 pen = 200 × 0.50 = $100
Cost of one pad =$0.70
Cost of 150 pads = 150 × 0.70 = $105
Cost of one pencil = $0.20
Cost of 100 pencils = $20
Total cost of the order = 100 + 105 + 20 = $225
Discount % = 15% of 225
Discount price = ( 15% × 225) = $33.75
Total amount after discount = 225 - 33.75 = $191.25

What is alternate angles?The alternate exterior angle theorem states that if two lines are parallel and are intersected by a transversal, then the alternate exterior angles are considered as congruent angles or angles of equal measure.
Here given:
AB II DE, AC = CE
Now, in ΔABC and ΔEDC
As, AB II DE (given)
⇒∠BAC = ∠CED (Alternative pairs of angles)
and ∠ABC = ∠CDE (Alternative pairs of angles)
and AC = CE (given)
So, by the congruent property of AAS
(ANGLE ANGLE SIDE) which states that two triangle are congruent if two angles and one side of one triangle is equal to the two angles and one side of the other triangle.

A rectangular. Garden bed measures 8 x 6 feet a water faucet is at one corner of the bed hose must be long enough to reach opposite corner when stretched straight. Find required length of hose
Answer:
10 ft
Step-by-step explanation:
The word problem is basically asking the length of one corner of the rectangle to the other. We can split the rectangle up into two right triangles and we will use the Pythagorean theorem to find the hypotenuse or the length from one corner to another. A^2 + B^2 = C^2 A and B are the lengths of the rectangle, 8 and 6. 8^2 + 6^2 = C^2
8^2 = 64 and 6^2 = 36
64 + 36 = 100.
the square root of 100 is 10 so the length of the hose is `10.
Chan drew the triangle below. Which two angles are congruent?
Answer:
Q and R
Step-by-step explanation:
So lets look at the triangle.
P seems very thin, wheareas Q and R seem wider.
Normally, if given the degrees of the angles, we can subtract them from 180, which is the degrees of a full triangle, to find if two or more angles are congruent.
In this case however, we just go off of looks.
We see that angle P points strait up. This would not be the case if either Q or R where not going at the same angle, for if they were not congruent, angle P would be tilted to either the left or rihgt side.
So in the end, the best answer is Q and R.

What should the m<3 be for —- ?
9514 1404 393
Answer:
m∠3 = 63°
Step-by-step explanation:
Where a transversal crosses parallel lines, all of the obtuse angles are congruent, and all of the acute angles are congruent. The obtuse and acute angles are supplementary.
Angle 1 is an obtuse angle; angle 3 is an acute angle.
angle 3 = 180° - angle 1 = 180° -117° = 63°
The measure of angle 3 is 63°.
_____
Additional comment
There are a number of applicable theorems describing the different angle relationships. Taken together, they are summarized by the first statement above. For example, we could declare angles 1 and 4 to be "corresponding" (hence, congruent), and angles 4 and 3 to be a "linear pair", hence supplementary. The net result is that angle 1 is supplementary to angle 3, as we said above.
We could also get there via relations between alternate exterior angles, alternate interior angles, consecutive exterior or interior angles, and other ways. While that terminology is useful to understand in some problems, it is largely irrelevant here.

Answer:
Daniel traveled further by 2.73 miles
Step-by-step explanation:
To find the total distance traveled simply multiply average speed times time
For Wendy
She traveled for 3.9 hours at a speed of 68.3 mph
So total distance traveled = 3.9 * 68.3 = 266.37 miles
For Daniel
He traveled for 4.5 hours at a speed of 59.8 mph
So total distance traveled = 4.5 * 59.8 = 269.1 miles
As you can see Wendy traveled 266.37 miles and Daniel traveled 269.1 miles
Daniel traveled further
To find how much further we simply subtract distance Daniel traveled (269.1) from distance Wendy traveled (266.37)
269.1 - 266.37 = 2.73
So Daniel traveled further by 2.73 miles

A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean, µ for the probability distribution.
x P(x)
-500 0.076
-250 0.191
0 0.265
250 0.316
500 0.152
Answer:
The mean is [tex]\mu = 69.25[/tex]
Step-by-step explanation:
We are given the following distribution:
P(x = -500) = 0.076
P(x = -250) = 0.191
P(x = 0) = 0.265
P(x = 250) = 0.316
P(x = 500) = 0.152
Find the mean, µ for the probability distribution.
To find the mean, we multiply each outcome by its probability. So
[tex]\mu = -500*0.076 - 250*0.191 + 0*0.265 + 250*0.316 + 500*0.152 = 69.25[/tex]
The mean is [tex]\mu = 69.25[/tex]

x/2-y/3=3,4x-3y=22
[tex] > < [/tex]
Answer:
x = 10
y = 6
Step-by-step explanation:
x/2 - y/3 = 3 - - - (1)
4x - 3y = 22 - - - (2)
From (1):
x/2 - y/3 = 3
(3x - 2y)/6 = 3
3x - 2y = 18 - - - - (11)
4x - 3y = 22 - - - - (2)
Multiply (11) by 1.5
4.5x - 3y = 27 _____(111)
4x - 3y = 22 - - - (2)
Subtract :
0.5x = 5
x = 5 / 0.5 = 10
From :
4x - 3y = 22
Put x = 10
4(10) - 3y = 22
40 - 3y = 22
-3y = 22 - 40
-3y = - 18
y = 6

Answer:
$24.00=$21.50+r*$.50
Step-by-step explanation:
total cost= entrance fee + r (number of rides) * $0.50 (cost of rides)
$24.00=$21.50+r*$.50
