Answer:
Hexagon
Step-by-step explanation:
It has more than 3 sides because it is more sides than a triangle and less than 5 since it has to be fewer sides than a pentagon. A hexagon has 6 sides meaning it has more sides than the pentagon.
Answer:
It should be hexagon
Step-by-step explanation:
Hex equals 6 and quad equals 4, so it would not be quadrilateral or square or recanatgle. So hexagon is your answer.

Give an example showing why one of the methods is not correct.
Answer:
Brandon's methot is not correct
for example: x=9 9×1/2=4.5
Here's why:
Let's use his method to find the square root of 36. That means we multiply 36 by 1/2 = 0.5 to get 36*0.5 = 18; however, 18 is not the square root of 36. We can see that 18*18 = 324. Instead, the square root of 36 is 6 because 6*6 = 36.
As another example, let's say we want to find the square root of 64. With Brandon's method, we would get to 64*0.5 = 32, but 32*32 = 1024. Ashley's method is correct and 8*8 = 64 shows that 8 is the square root of 64.
As a visual approach, think of a square with side lengths 8 feet each. The area would be 8*8 = 64 square feet. If you didn't know the side length, but you knew that the area was 64 square feet, then you could apply the square root operation to find the side length to be 8 feet (or you could effectively use Ashley's guess-and-check method to arrive at 8 feet). In short, the square root operation is the opposite of squaring a number. We consider these inverse operations.
Multiplying by 1/2 is the same as dividing by 2. Division is the opposite of multiplication, and division is not the inverse of squaring a number. It's just a coincidence that Brandon's method happened to work on the value 4. But as shown earlier, it doesn't work in general.
Find the area of the trapezoid.
Answer:
78 ft squared
Step-by-step explanation:
To find the area of trapezoid, we could use this formula:
.5*height*(sum of bases)
We know both the base lengths. They are 10 and 16 ft.
The height can be found by looking at that right triangle whose base is (16-10) ft or 6 ft.
So we want to find the height which is opposite the 45 degree angle and we have the adjacent side's measurement of 6ft.
This has the tangent ratio written all over it since tangent of an angle is opposite side's measurement over adjacent side's measurement.
tan(45)=height/6
1=height/6
6=height
6ft=height
The answer is:
.5*height*(sum of bases)
.5*6 ft*(10 ft+16 ft)
3 ft(26 ft)
78 ft squared
Note: That one right triangle is an isosceles right triangle so we didn't need trigonometry.
0. The mean of the numbers 4, 3, 3, x is 5
Find x.
A. 20
B. 10
C. 5.
D. 4
Answer:
x = 10.
Step-by-step explanation:
From the definition of the mean:
(4 + 3 + 3 + x) / 4 = 5
4 + 3 + 3 + x = 20
x + 10 = 20
x = 10.

Which statement is the most appropriate comparison of the centers?
It's D. the median for town A, 30, is less than the median for town B, 40.
The median for town A at 30° is less than the median for town B at 40°.
So, option (D) is the correct answer.
What is the median?The median is the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number".
For the given diagram,
Town A has temperatures = 20°, 30°, 40°
Town B has temperatures = 30°, 40°, 50°
The median of A = 30°
The median of B = 40°
Hence, From the above values, the median for town A at 30° is less than the median for town B at 40°.
Hence, we can conclude that option (D) is the correct answer.

Tori has a cell phone plan that charges $0.09 for each text message sent. Tori plans to spend no more than $40 per month on texting bill each month. If c(t) = 0.09t represents the total
mumber of text (that you send each month.
The domain of the function is x
Answer: [tex]t<444.44[/tex]
Step-by-step explanation:
Given
Texting bill is given by [tex]c(t)=0.09t[/tex]
Spending must be less than [tex]\$40\ \text{per month}[/tex]
So, text billing must be less than $40
[tex]\therefore 0.09t<40\\\\\Rightarrow t<\dfrac{40}{0.09}\\\\\Rightarrow t<444.44[/tex]

12. The table of values below describes a quadratic relation. Find the missing value and include calculations that demonstrate that this is the correct value.
Answer:
The quadratic equation is;
y = 3x^2-7x + 5
when x = 4, y = 25
Step-by-step explanation:
Mathematically, the general form of a quadratic equation is;
y = ax^2 + bx + c
From the first point, we have that x = 0
Thus;
5 = a(0)^2 + b(0) +c
c = 5
Now, in a case when x is 2
3 = a(2)^2 + b(2) + 5
3 = 4a + 2b + 5
4a + 2b = -2 ••••••(i)
when x = 6
71 = a(6)^2 + b(6) + 5
66 = 36a + 6b ••••••(ii)
From equation i,
2b = -2-4a ••••(iii)
we can rewrite equation ii as
66 = 36a + 3(2b)
Substitute iii into ii
66 = 36a + 3(-2-4a)
66 = 36a - 6 - 12a
66 + 6 = 36a -12a
24a = 72
a = 72/24
a = 3
Recall;
2b = -2-4a
2b = -2-4(3)
2b = -2-12
2b = -14
b = -14/2
b = -7
So the quadratic equation would be;
y = 3x^2 -7x + 5
Now let us test;
when x = 10, y = 235
That would be:
y = 3(10)^2 -7(10) + 5
y = 300 - 70 + 5
y = 235
This shows that the derived quadratic equation is correct
Now, when x = 4; we have it that;
y = 3(4)^2 -7(4) + 5
y = 48 -28 + 5
y = 20 + 5 = 25

Step-by-step explanation:
Put the one shape and split it into two other shapes. A square and a triangle.
find the areas of both of the shapes and add them together.
5×5=25
5×12=60/2 = 30
25+30=55
Answer:
55 units²
Step-by-step explanation:
The area of this shape would be the area of a square with sides 5 and a triangle with a base of 5 and a height of 12
To find the area of this shape, add the area's of the two shapes
This would be written as:
[tex]5^{2} +\frac{5*12}{2} \\ =25+(5*6)\\ =25+30\\= 55[/tex]

Step-by-step explanation:
So a rebate is like a refund which means:
A) 120(.8) = 96 You use .8 because you’re paying 80%
B) 120-30= 90
C) 120(.85) = 102 you use .85 because you’re paying 85%, now
102-15= 87 Subtract 15 since you get a $15 rebate
D) 120(.9)=108 You use .9 since you are paying 90%
108-20= 88 Subtract 20 since you get a $20 rebate
since C ended up with the lowest price, the answer is C

El diametro de rueda de esta bicicleta mide 80 cm. Si ha dado 10.000 vueltas, ¿cuantos kilimetros ha recorrido?
Answer:
Ha recorrido 8 km.
Step-by-step explanation:
Primero debes multiplicar el diámetro de la rueda por el número de vueltas que ha dado para encontrar cuánto ha recorrido:
80cm*10.000=80.000 cm
Ahora, debes convertir los 800.000 cm a km usando una regla de tres considerando que 1 km es igual a 100.000 cm:
1 km → 100.000 cm
x ← 800.000 cm
x=(800.000*1)/100.000
x=8 km
De acuerdo a esto, la respuesta es que ha recorrido 8 km.
