This number can have a maximum value of 18.64.
What are decimal numbers?The decimal numeral system is the most widely used system for representing both integer and non-integer numbers. It is the Hindu-Arabic numeral system's extension to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system. Non-recurring (non-repeating or terminating, for example), recurring (repeating or non-terminating, for example), and decimal fractions are the three types of decimals (a.k.a. converting a decimal into a fraction whose denominator is a power of ten).So, when rounded to the nearest tenths, the number is 18.59.
Now, look at the number to the right of it.If that number is 5 or higher, we round the 5 to a 6.But if that number is 4 or lower, the number remains a 5.18.55 rounded to the nearest tenths equals 18.6 (because the number to the right of 5 is 5, we round up to 18.6)18.54 rounded to tenths = 18.5 (because the number to the right of the 5 is 4, so we round it to 18.5).Therefore, this number can have a maximum value of 18.64.

The sum of two numbers is 15. Using x to represent the smaller of the two numbers, translate "the sum of twice the smaller number and two more than the larger num ber" into a variable expression. Then simplify.
Answer:
Step-by-step explanation: Let x be the smaller and y be the largest number.
Since x+y=13, we deduce y=13-x
Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x
Their sum is y+2+2x
And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x

Step-by-step explanation:
As you can see, the term-to-term rule of the sequence is +2
We can use that to calculate the amount of terms.
First, calculate the distance between the first and last terms
53 - 19 = 34
Then, use this and divide the term-to-term rule.
34/ 2 = 17

The intersection of Sets :
The intersection of sets for two given sets is the set that contains all the elements that are common to both sets. The symbol for the intersection of sets is "∩''. For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets, and are the common elements of A and B.
Intersections of sets have properties similar to the properties of numbers. The properties of the intersection of sets include the commutative law, associative law, the law of null set and universal set, and the idempotent law. The following table lists the properties of the intersection of sets.
Name of Property/Law Rule
Commutative Law A ∩ B = B ∩ A
Associative Law (A ∩ B) ∩ C = A ∩ (B ∩ C)
Law of ϕ and U ϕ ∩ A = ϕ , U ∩ A= A
Idempotent Law (A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)
(A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C)
Important Notes:
(A ∩ B) is the set of all the elements that are common to both sets A and B.
If A ∩ B = ϕ, then A and B are called disjoint sets.
n(A ∩ B) = n(A) + n(B) - n(A ∪ B)

Answer:
C
Step-by-step explanation:
Find a. (f+g)(x) b. (f+g)(6).
f(x)=3x2−x−6, g(x)=x−4
We get that the value of (f + g)(x) is 3 x² - 2 x - 10 and (f + g)(6) is 86.
We are given the two functions:
f(x) = 3 x² - x - 6
g(x) = x - 4
We need to find:
(f + g)(x)
= f(x) +g(x)
= 3 x² - x - 6 + x - 4
= 3 x² - 2 x - 10
Now we have to find:
(f + g)(6).
Put x = 6, we get that:
= 3 (6)² - 2 (6) - 10
= 108 - 12 - 10
= 108 - 22
= 86
Therefore, we get that the value of (f + g)(x) is 3 x² - 2 x - 10 and (f + g)(6) is 86.

the maximum number of candy kisses that each person could have received is 4.
What was the greatest possible number of candy kisses each person could have received?We know that each person receives the same number of candy.
Now, one group of K people receives 20 candy.Another group of N people receives 52 candy.Then the quotients between the number of candy and the number of people should give the same value:
20/K = 52/N
Let's find the common factors between 20 and 52, to do so, we need to rewrite the two numbers as a product of prime factors:
20 = 2*10 = 2*2*5
52 = 2*26 = 2*2*13
The greatest common factor between 20 and 52 is (2*2) = 4
Then, if each person receives 4 candy:
The group that receives 20 candy:
20/K = 4
20/4 = k = 5
That group has 5 people.
The group that receives 52 candy:
52/N = 4
52/4 = N = 13

Given data
50 vehicles belong to an enterprise that has three departments, A, B and C
6 vehicles are available for the use of all three departments
2 vehicles give service to neither of the departments
24 vehicles are administrated by department B
16 of the 24 used by B are also used by the others departments
There are twice as many vehicles in department A as there are in department C.
equal numbers of vehicles are allocated when used by any two departments
How to find the number of vehicles administrated by each departmentnumber of vehicles on department A = 2 * number of vehicles in department C.
say A = 2C
B = 24
let x represent the number of vehicles used by any two departments
16 of the 24 used by B are also used by the others departments and equal numbers of vehicles are allocated when used by any two departments hence
16 = 2x + 6
2x = 16 - 6
2x = 10
x = 5
B only = 24 - 2x - 6 = 18 - 2x = 18 - 10 = 8
A only = A - 2x - 6 = 2C - 10 - 6 = 2C - 16
C only = C - 2x - 6 = C - 10 - 6 = C - 16
adding up all the vehicles as allocated to get to the sum of 50
24 - 2x - 6 + A - 2x - 6 + C - 2x - 6 + x + x + x + 6 + 2 = 50
24 - 6 - 6 - 6 + 6 + 2 - 2x - 2x - 2x + x + x + x + A + C = 50
24 - 10 - 6x + 3x + 2C + C = 50
14 - 3x + 3C = 50
3C - 3X = 50 - 14
3C - 3(5) = 36
3C - 15 = 36
3C = 36 + 15 = 51

Answer:

Step-by-step explanation:
Given dimensions of rectangle ABCD:
width = xlength = (x + 4)[tex]\begin{aligned}\textsf{Area of a rectangle} & = \sf width \times length\\\\\implies \sf Area\:of\:ABCD& = x(x+4)\\& = x^2+4x \end{aligned}[/tex]
Given dimensions of isosceles triangle ADE:
Base = DE = xHeight = AD = x[tex]\begin{aligned}\textsf{Area of a triangle} & = \dfrac{1}{2} \times \sf base \times height\\\\\implies \textsf{Area of $\triangle$ADE}& = \dfrac{1}{2} \cdot x \cdot x\\& = \dfrac{1}{2}x^2\end{aligned}[/tex]
As the area of the portion remaining when ADE is cut off from ABCE is 6 m²:
[tex]\begin{aligned}\sf ABCD-ADE & = 6\\\implies x^2+4x-\dfrac{1}{2}x^2 & = 6\\2x^2+8x-x^2 & = 12\\x^2+8x & = 12\\x^2+8x-12 & = 0\end{aligned}[/tex]
Solve the found quadratic equation by completing the square.
Move the constant to the right side of the equation:
[tex]\implies x^2+8x-12+12=0+12[/tex]
[tex]\implies x^2+8x=12[/tex]
Add the square of half the coefficient of x to both sides:
[tex]\implies x^2+8x+\left(\dfrac{8}{2}\right)^2=12+\left(\dfrac{8}{2}\right)^2[/tex]
Simplify:
[tex]\implies x^2+8x+4^2=12+4^2[/tex]
[tex]\implies x^2+8x+16=12+16[/tex]
[tex]\implies x^2+8x+16=28[/tex]
Factor the perfect square trinomial on the left side:
[tex]\implies (x+4)^2=28[/tex]
Square root both sides:
[tex]\implies \sqrt{(x+4)^2}=\sqrt{28}[/tex]
[tex]\implies x+4=\pm \sqrt{28}[/tex]
[tex]\implies x+4=\pm \sqrt{4 \cdot 7}[/tex]
[tex]\implies x+4=\pm \sqrt{4}\sqrt{7}[/tex]
[tex]\implies x+4=\pm 2\sqrt{7}[/tex]
Subtract 4 from both sides:
[tex]\implies x=-4\pm 2\sqrt{7}[/tex]
As length is positive:
[tex]\implies x=-4+ 2\sqrt{7}\:\:\sf only[/tex]
Taking the value of √7 = 2.65:
[tex]\implies x \approx -4+ 2(2.65)[/tex]

An aeroplane when flying at a height of 2000m from the ground passes vertically above a helicopter at an instant when their angles of elevation from the same point on the ground are 60⁰ and 30 respectively. Find the vertical distance of the helicopter from the ground.
The vertical distance of helicopter from the ground is equal to 2000 / 3 m.
Let the distance between the two planes A and B be x.
In △ ADC, we get that:
tan 60° = 2000 / y
√3 = 2000 / y ...(1)
Now, in △ BCD, we get that:
tan 30° = 2000 - x / y
1 / √3 = (2000 - x) / y ... (2)
Divide (1) from (2):
3 = 2000 / (2000 - x)
6000 - 3 x = 2000
3 x = 6000 - 2000
3 x = 4000
x = 4000 / 3
(2000 - x) = 2000 - 4000/3 = 2000 / 3
Therefore, the vertical distance of helicopter from the ground is equal to 2000 / 3 m.

What is g(h(10))?
O 2√2
√6
√6-8
02√6-8
The value of g(h(10)) is 2√2. the correct option is A.
Given that the functions are g(x)=√x-4 and h(x)=2x-8.
A function is defined as the relationship between a set of inputs where each input has an output.
Firstly, we will find the value of h(10) by substituting x=10 in the function h(x)=2x-8.
h(10)=2(10)-8
h(10)=20-8
h(10)=12
Now, we will find g(h(10)) where h(10)=12.
By substituting h(10)=12 in g(h(10)), we get
g(h(10))=g(12).
Further, we will find g(12) by substituting x=12 in the function g(x)=√x-4, we get
g(12)=√(12-4)
g(12)=√8
g(12)=2√2
Hence, the value of function g(h(10)) when g(x)=√x-4 and h(x)=2x-8 is 2√2.

A car travels at an average speed of 52 miles per hour How many miles does it travel in 4 hours and 45 minutes
Answer: 247 miles.
Step-by-step explanation: First, we need to convert the 45 minutes into hours. we know that 1 hour = 60 minutes. Dividing any number of minutes by sixty gives us the number of hours along with the remaining minutes if there are any. so 45/60 simplifies to 3/4. Now for the miles, it's given that the speed is 52 mph. So we can put into the expression 52(4+3/4)= total miles. Once we distribute 52, we get 208 + 39, which equals to 247.
Answer:
