a positive integer n is called special if n is divisible by 4, N+1 is divisible by 5 and n+2 is divisible by 6. how many special integers smaller than 1000 are there?
Answer:
17
Step-by-step explanation:
these positive integers are :
4, 64, 124, 184 ... , 964
964 = 4 + (n-1) (60)
964 = 4 + 60n -60
964 = 60n -56
60n = 1020
n = 1020/60
n = 17
so, the number of special integers smaller than 1000 are = 17

A triangle has side lengths of 2x , x + 4, and 3 (x + 3). Find the value of x if the perimeter of the triangle is 55 inches.
Answer:
x=7
Step-by-step explanation:
55=2x+(x+4)+[3(x+3)]
55=2x+x+4+3x+9
55=6x+13
55-13=6x
42=6x
7=x
Answer:
7 inchesStep-by-step explanation:
Perimeter is the sum of side lengths:
P = 2x + x + 4 + 3(x + 3)P = 55Solve for x:
2x + x + 4 + 3(x + 3) = 553x + 4 + 3x + 9 = 556x + 13 = 556x = 55 - 136x = 42x = 42/6x = 7dy/dx y = 3root(4x+1) -2x
Answer:
Step-by-step explanation:
y = 3(4x + 1)^1/2 - 2x
dy/dx = 3*1/2(4x + 1)^-1/2 * 4 - 2
= 4 * 1.5 (4x + 1)^-1/2 - 2
= 6(4x + 1)^-1/2 - 2
= [6/√(4x + 1)] - 2
y = 3(4x + 1)^1/2 - 2x
∫3(4x + 1)^1/2 - 2x . dx
= 3 * 1/4 * (4x + 1)^3/2 / 3/2 - x^2 + C
= 3/4 * 2/3 (4x + 1)^3/2 - x^2 + C
= 1/2((4x + 1)^3/2 - 2x^2) + C.
Answer:
Step-by-step explanation:
[tex]y=3*\sqrt{4x+1} -2x\\\\y'=\dfrac{dy}{dx} =\dfrac{3}{2*\sqrt{4x+1} } -2\\\\\\\int {(3*\sqrt{4x+1} -2x}) \, dx \\\\=\dfrac{3}{4} *\int {4*(4x+1)}^{\frac{1}{2}} \, dx -2\int {x} \, dx \\\\=\dfrac{-3}{4}*\sqrt{(4x+1)^3} *\dfrac{2}{3} }-x^2+C\\\\=\dfrac{\sqrt{(4x+1)^3}}{2} -x^2+C[/tex]

Answer: x= 26
Step-by-step explanation:
27+x+127 = 180(being linear pair)
or, x + 154 = 180
or, x = 180-154
so, x = 26
Answer:
26
Step-by-step explanation:
Here,
27+ 127+ x =180
154+ x = 180
x =180-154
x=26

Answer:
A. Selection Bias
Step-by-step explanation:
Selection bias is the bias introduced by the selection of individuals, groups, or data for analysis in such a way that proper randomization is not achieved, thereby ensuring that the sample obtained is not representative of the population intended to be analyzed. This is represented by choosing the students without glasses.

I need help with Shape equation puzzle 2 it’s due tomorrow
Hey there! I'm happy to help!
First of all, I would guide you to decipher clue 2 first. It is the only one that has just one shape, so then we can find the value of that shape.
To find what this circle is, we just divide 12 by three to see what 3 times the circle is!
12÷3=4
CIRCLE=4
-----------------------------------------------------------------
Now, let's look at clue one. This one only has two shapes, and it has the circle, which we already know.
We know that our circle is 4, so 5 circles will be 20.
This means that the diamond plus two will be 20, so let's just subtract 2 from 20!
20-2=18
DIAMOND=18
-----------------------------------------------------------------
Finally, let's look at the third one. This one is the trickiest. Two circles is eight, and that is going to be equal to our diamond (eighteen) and two triangles.
How is that going to work?
The triangles make us go backwards! Otherwise known as negative numbers!
To get from eighteen to eight, we have to go back ten. Ten is going to be made up of two triangles, so we just divide ten by two so each triangle gets an equal amount.
10÷2=5
TRIANGLE=5
-----------------------------------------------------------------
Have a wonderful day and keep on learning! :D
An equation is formed of two equal expressions. The value of the Circle, Diamond, and the triangle is 4, 18, and -5, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the circle be represented by C, the diamond be represented by D, and the triangle be represented by T.
Now, the clues can be rewritten as,
D + 2 = 5(C)
3(C) = 12
2(C) = D + 2(T)
Since the second clue has only one variable C, let's solve it first,
3(C) = 12
C = 12 / 3
C = 4
Further, the first clue has two variables C and D, and the value of C is already known, therefore, solve it second.
D + 2 = 5(C)
D + 2 = 5(4)
D + 2 = 20
D = 20 - 2
D = 18
Furthermore, by solving the last Clue we will get,
2(C) = D + 2(T)
Substitute the known values,
2(4) = 18 + 2(T)
8 = 18 + 2T
8 - 18 = 2T
-10 = 2T
T = -5
Hence, the value of the Circle, Diamond, and the triangle is 4, 18, and -5, respectively.

a number set consists of {4，5，6，7}。How many 2-digit combinations of numbers from the data set can be divided by 3？
Answer:
5
Step-by-step explanation:
This trick works with 3:
If the sum of the digits of a number is divisble by 3 then the number is divisble by 3.
44 is not divisble by 3 because 4+4=8 is not divisble by 3.
45 is divisble by 3 because 4+5=9 is divisble by 3.
46 is not divisble by 3 because 4+6=10 is not divisble by 3.
47 is not divisble by 3 because 4+7=11 is not divisble by 3.
54 is divisble by 3 because 5+4=9 is divisble by 3.
55 is not divisble by 3 because 5+5=10 is not divisble by 3.
56 is not divisble by 3 because 5+6=11 is not divisble by 3.
57 is divisble by 3 because 5+7=12 is divisble by 3.
64, 65,67 are not divisble by 3 because their digits' sums are 10,11, and 13 respectively. 66 is a winner because 6+6=12 is divisble by 3.
Finally 7...
74,76,77 are not divisble by 3 because their digits' sums are 11,13, and 14 respectively. 75 is divisble by 3 because 7+5=12 is divisble by 3.

Please help me with this question, and show working out.
===============================================================
Explanation:
If you used scissors to cut a vertical slice down the lampshade, then it can be unrolled to form a rectangle.
The horizontal portion of this rectangle is the distance around the circle, which is the perimeter of the circle, or the circumference. That's C = 2pi*r. Check out the diagram below to see what I mean.
The diagram shows that the diameter is 20 cm, so the radius is half that at 20/2 = 10 cm.
The circumference is C = 2*pi*r = 2*pi*10 = 20pi cm exactly
The height of the rectangle is the height of the cylinder, which is h = 30 as shown in the diagram.
The area of the rectangle is length*height = (20pi)*(30) = 600pi square cm exactly.
If we were to use something like pi = 3.14, then its approximate area is 600*pi = 600*3.14 = 1884 square cm
Let's bump this up by 10%. To do so, we'll multiply by 1.10
1.10*1884 = 2072.4

You deposit $300 into a savings account that is compounded annually. The function g(x) = 300(1.04)x can be used to find the amount of money in the savings account after x years. What is the constant percent rate of change?
Answer:
This is a simple interest, as the amount earned each year is constant
Step-by-step explanation:
Using compound interest, it is found that the constant percent rate of change is of 4%.
--------------------
The formula for an amount of money invested into compound interest is given by:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which:
A(t) is the amount after t years.A(0) is the initial amount.r is the constant percent rate of change.t is the time.--------------------
The function is:
[tex]g(x) = 300(1.04)^x[/tex]
Thus, for the constant percent rate of change:
[tex]1 + r = 1.04[/tex]
[tex]r = 1.04 - 1 = 0.04[/tex]
[tex]0.04 \times 100\% = 4\%[/tex]
The constant percent rate of change is of 4%.

Which of the graphs model the equation y= x^2?
Answer:
Step-by-step explanation:
The general equation for a parabola is y=4(x^2). The given eqn is y=x^2.
The equation resembles a parabola.
So clearly the answer is either B or C.
Now substitute some values. The value of y can't be negative because x^2 will always be positive.
The answer is B.
find the two number whose A.M is 5 and G.M is 4
Answer:
2 and 8
Step-by-step explanation:
let the numbers be x and y , then
[tex]\frac{x+y}{2}[/tex] = 5 ( multiply both sides by 2 ) ← AM
x + y = 10 → (1)
[tex]\sqrt{xy}[/tex] = 4 ( square both sides ) ← GM
xy = 16 → (2)
From (1) , expressing x in terms of y
x = 10 - y ← substitute into (2)
(10 - y)y = 16
10y - y² = 16 ( subtract 16 from both sides )
10y - y² - 16 = 0 ( multiply through by - 1 )
y² - 10y + 16 = 0 ← in standard form
(y - 2)(y - 8) = 0 ← in factored form
Equate each factor to zero and solve for y
y - 2 = 0 ⇒ y = 2
y - 8 = 0 ⇒ y = 8
Substitute into (1)
x + 2 = 10 ⇒ x = 8 or x + 8 = 10 ⇒ x = 2
The 2 numbers are 2 and 8

Step-by-step explanation:
x² - xy = 0
x + y = 1
Answer:
(0, 1 ) and ([tex]\frac{1}{2}[/tex], [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
Given the 2 equations
x³ - xy = 0 → (1)
x + y = 1 → (2) ( subtract x from both sides )
y = 1 - x → (3)
Substitute y = 1 - x into (1)
x² - x(1 - x) = 0
x² - x + x² = 0
2x² - x = 0 ← factor out x from each term on the left side
x(2x - 1) = 0
Equate each factor to zero and solve for x
x = 0
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
Substitute these values into (3) for corresponding values of y
x = 0 : y = 1 - 0 = 1 ⇒ (0, 1 )
x = [tex]\frac{1}{2}[/tex] : y = 1 - [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{2}[/tex] ⇒ ( [tex]\frac{1}{2}[/tex], [tex]\frac{1}{2}[/tex] )
