Which two of the following numbers are rational?
1/3
.10
.π
√2
Answer:
1/3, 0.10
Step-by-step explanation:
Rational numbers can be expressed as a fraction of two integers.
1/3 is rational. When it is expressed as a fraction, it's 1/3. 1 is an integer, and 3 is an integer
0.10 is rational. It can be rewritten to be expressed as the fraction 1/10; 1 is an integer, and 10 is an integer.
.[tex]\pi[/tex] is irrational, because when expressed as a fraction, it is 1/[tex]\pi[/tex]. 1 is an integer, but [tex]\pi[/tex] is not. Both numbers need to be integers in order to be rational. Therefore, it is irrational
√2 is irrational. When expressed as a fraction, it's √2/1. √2 is not an integer. 1 is an integer. However, both numbers have to be integers in order to be rational. Therefore, √2 is not rational.
A 16 ft monument consists of a rectangular prism and a square pyramid, as shown below. If the exposed surfaces of the monument are to be covered with one-inch square tiles, determine approximately how many tiles will be needed.
Answer and Step-by-step explanation:
The actual answer is 348.
4 rectangles with area 60 each, which, when added together, equals 240.
1 square with area 36.
Each triangle face is 18 each, so 72.
Add those together and the answer is 348 [tex]ft^2[/tex] :).

What are the factors of the expression x^2+x-20?
Answer:
(x-4)(x+5)
Step-by-step explanation:
Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)

Answer:
126.5
Step-by-step explanation:
The polygon is made up of a rectangle and a triangle.
rectangle: 11 cm by 8 cm
triangle: base = 11 cm; height = 7 cm
area = LW + bh/2
area = 11 cm * 8 cm + (11 cm)(7 cm)/2
area = 88 cm^2 + 77/2 cm^2
area = 88 cm^2 + 38.5 cm^2
area = 126.5 cm^2
2. ALMN and APMN are shown below. What additional information is necessary to prove
ALMN = APMN by HL?
Help please!!!
Answer:
The additional information necessary is option;
D. [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Step-by-step explanation:
From the given figure, we have;
Given that ML ≅ MP,
The Hypotenuse Leg HL theorem of congruency is used to prove that a given number of right triangles based on the lengths of their hypotenuse and one of the legs. It states that two or more right triangles are congruent if they have equal lengths of both their corresponding hypotenuse side and one leg
To prove that ΔLMN and ΔPMN are congruent by HL, we will also be required to prove that ΔLMN and ΔPMN are right triangles
For ΔLMN and ΔPMN to be right triangles, the angles, ∠LNM and ∠PNM should be right angles = 90°
With ∠LNM = ∠PNM = 90°, then, line [tex]\overline {MN}[/tex] is perpendicular to line [tex]\overline {LP}[/tex] or [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Therefore, the additional information necessary to prove that ΔLMN ≅ ΔPMN by HL is [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex].
What is the other shape in the composite figure besides the rectangular prism?
triangular pyramid
square pyramid
triangular prism
cube
Answer:
cube
Step-by-step explanation:
The shape in the middle of the two rectangular prism would be a cube. This is the case since the angle at the base of the rectanglular prism forms a 90-degree angle. This indicates that the line is a straight line and would also form a 90-degree angle with the bottom angles as well. This would ultimately indicate that it forms a square, and since the shape is a 3-Dimensional shape it would be classified as a cube in this image.
Answer:
Triangular Prism
Step-by-step explanation:
The middle shape is a rectangular prism.
The top and bottom is a Triangular Prism.
Josh spent $30 at the movies. 1/5 was spent on a drink, 45% on a ticket and the rest on food. How much did he spend on food?
Answer:
$10.5
Step-by-step explanation:
Given data
Total amount=$30
Drink = 1/5*30= $6
Ticket= 45% of 30
=45/100*30
=0.45*30
=$13.5
The remainder is for food
=30-6-13.5
=$10.5

What is the greatest common factor of 18, 24, and 40?
Answer:
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Then the greatest common factor is 2.
The greatest common factor of 18 , 24 and 40 is HCF = 2
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF be represented as H
Let the first number be represented as p
Now , the value of p = 18
Let the second number be represented as q
Now , the value of q = 24
Let the third number be represented as r
Now , the value of r = 40
And , the factors of 18 = 1, 2, 3, 6, 9 and 18
The factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24
The factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40
So , the HCF of 18 , 24 and 40 is the number 2
Hence , the HCF is 2

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
Suppose the other parallel side is [tex]x[/tex]
The area of the trapezium is
[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]
Put values
[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]

Uma professora de artes pediu aos alunos para montarem mosaicos unindo peças. Nesse mosaico, essas peças deveriam ficar sempre ligadas pelos vértices, não poderiam se sobrepor e não deveria sobrar espaço entre elas. Além disso, para fazer esse mosaico, essa professora solicitou que todos os alunos utilizassem octógonos regulares, como o que está apresentado abaixo.
M100839H6_1
Para compor esse mosaico, junto com esses octógonos, os alunos tinham à sua disposição as peças do quadro abaixo.

III e IV.
Answer:
coloquei a letra d- II, III e IV
Step-by-step explanation:
Answer:
é a letra D (II, III e IV)
Step-by-step explanation:
se você reparar no ângulo interno da figura do octógono está mostrando 135º e a primeira figura que no caso não encaixa mostra 60º, fazendo essa soma daria um total de 195º, o que passa de 180º que é a metade de uma circunferência, então não daria certo, ficaria uma parte sobrando, não se encaixando no mosaico.

find the median and mean 42,15,14,48,39
Answer:
Hello! the answer is 39 and 32
Step-by-step explanation:
To find the median we need to reorder the numbers from lowest to highest:
14,15,39,42,48
The one in the middle is the median! If there happens to be an even number, take the two middle numbers add them, together and divide them by 2.
To find the mean (also know as the avergae) we need to add all the numbers together and divide by the number of values that are present:
42+15+14+48+39 = 158
158/ 5 = 31.6 or 32
Hope this helps!

The maximum height reached by the barnacle is _______ m.
Answer:
1 answer is 1
2 answer is -1
3rd answer is 2pi
From the diagram, we can tell that the maximum height that is reached by the barnacle is 1m.
Why is this the maximum height?The Barnacle is going around the water level in the shape of a circle which the water level being the diameter.
This means that the maximum height the barnacle can reach is constricted by the radius such that it is the same as the radius of the circle. This means that the maximum height is 1m.
