Given :
A sequence of numbers consists of natural numbers that are
not perfect squares.
To Find :
The 1000th member of this sequence .
Solution :
Now , [tex]31^2=961[/tex] and [tex]32^2=1024[/tex] .
So , there are 31 numbers before 1000 which are perfect square .
Therefore , the [tex]999^{th}[/tex] is 1000+31 = 1031 .
Also , the first perfect square after 1000 is 32 .
So , we have to continue to 1031 + 1 = 1032 to compensate for the 32nd square.
Therefore , the 1000th member of this sequence is 1032 .
Hence , this is the required solution .
can you put this equation > 3 in a number line.
Answer:
>3 means any number on the number line larger than 3, so the answer is yes
4(−x + 4) = 12 multi step equation. show all steps with only numbers not words please
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4(-x+4)=12[/tex]
First, divide both sides by 4. The left side will cancel. The right will reduce to 3:
[tex](4(-x+4))/4=(12)/4\\-x+4=3[/tex]
Subtract 4 from both sides. The left cancels:
[tex]-x=-1[/tex]
Divide both sides by -1:
[tex]x=1[/tex]
So, the value of x is 1.
And we're done!
Answer:
x = 1
Step-by-step explanation:
4(-x + 4)= 12
Step 1 : Distribute
-4x + 16 = 12
Subtract 16 from both sides
-4x = -4
Divide
[tex]\frac{-4x}{-4}[/tex] = [tex]\frac{-4}{-4}[/tex]
x = 1
Bob has $3.69 in pennies, dimes, and quarters. The number of pennies is three more than the number of dimes. The number of quarters is twice the number of dimes. How many of each coin does he have?
Answer:
9 pennies, 6 dimes, 12 quarters.
Step-by-step explanation:
Pennies = $0.01
Dimes = $0.10
Quarters = $0.25
Let x be the number of dimes. Then (x + 3) is the number of pennies and 2x is the number of quarters.
We have x($0.10) + (x + 3)($0.01) + 2x($0.25) = $3.69
x($0.10) + (x + 3)($0.01) + 2x($0.25) = $3.69
$0.1x + $0.01x + $0.03 + $0.5x = $3.69
$0.61x = $3.66
x = 6.
Therefore Bob has 9 pennies, 6 dimes and 12 quarters.
1/4 + 1/2 + x = - 3/4
solve for x
Answer:
X=-3/2
Step-by-step explanation:
1/4+1/2+X=-3/4
X=-3/4-1/4-1/2
X=-3/2

5 MINS LEFT! A group of students decides to sell pizzas to help raise money for their senior class trip. They sold a pepperoni pizza for $14, a sausage pizza for $11, and a cheese pizza for $10. At the end of their sales, the class sold a total of 400 pizzas and made $4560. The students sold 80 more cheese pizzas than pepperoni pizzas. How many of each type of pizza were sold?
Answer:
The number of cheese pizza sold is 200 cheese pizzas
The number of sausage pizza sold is 80 sausage pizzas
The number of pepperoni pizza sold is 120 pepperoni pizzas
Step-by-step explanation:
The price at which the pepperoni pizza was sold is $14
The price at which the sausage pizza was sold is $11
price at which the cheese pizza was sold is $10
The total number of pizzas sold = 400
The total amount made = $4560
The number of cheese pizza sold = 80 + the number of pepperoni pizzas
Let the number of cheese pizza sold = C
The number of sausage pizza sold = S
The number of pepperoni pizza sold = P
We have;
C + S + P = 400..........................(1)
C = 80 + P...................................(2)
10·C + 11·S + 14·P = $4560.......(3)
Substituting the value for C from equation (2) in equation (1), we get;
C + S + P = 400 = 80 + P + S + P = 400
2·P + S = 400 - 80 = 320
∴ S = 320 - 2·P..........................(4)
Substituting the value for C from equation (2) and the value for S from equation (4) into equation (3), we get;
10·C + 11·S + 14·P = $4560
10·(80 + P) + 11·(320 - 2·P) + 14·P = 4560
800 + 10·P + 3,520 - 22·P + 14·P = 4560
4,320 + 2·P = 4560
2·P = 4560 - 4,320 = 240
P = 240/2 = 120
P = 120
C = 80 + P = 80 + 120 = 200
C = 200
S = 320 - 2·P = 320 - 2×120 = 320 - 240 = 80
S = 80
Therefore;
The number of cheese pizza sold = C = 200
The number of sausage pizza sold = S = 80
The number of pepperoni pizza sold = P = 120.

A parachutist's rate during a free fall reaches 117 miles per hour. What is this rate in feet per second? At this rate, how many feet will the parachutist fall during 10 seconds of free fall? In your computations
Answer:
1. rate = 171.6 feet/second
2. 1716 feet
Step-by-step explanation:
1. To convert from miles per hour to feet per second,
1 mile = 5280 feet
117 miles = 617760 feet
1 hour = 3600 seconds
Thus the rate in feet per second will be;
= [tex]\frac{617760}{3600}[/tex]
= 171.6 feet/second
2. In 10 second of free fall,
speed = [tex]\frac{distance}{time}[/tex]
distance = speed x time
= 171.6 feet/second x 10 second
= 1716 feet
The parachutist would fall 1716 feet in 10 seconds of free fall.

What is the sum of √-2 and √-18?
A) 4√2
B) 4√2i
C) 5√2
D) 5√2i
Answer: OPTION B
Step-by-step explanation:
First of all, you need to know the concept of imaginary number or i.
i (imaginary number)= √-1 ⇔ In real number world, √-1 will be undefined,
and thus this is called imaginary number
------------------------------------------------------------------
√-2=√2 × √-1
√2=√2√-1= i√-2=√2× √-1
√-2=√2 × i
√-2= √2 i
---------------------------------------
√-18=√9 × √2 × √-1
√9=3 ⇒ This is a perfect square√2=√2√-1=i√-18= √9 × √2 × √-1
√-18= 3 × √2 × i
√-18= 3√2 i
----------------------------------------
Addition in radical numbers is as usual as normal number. HOWEVER, only numbers that has the same radical (i.e 2√3 and 7√3) can combine.
√-2 + √-18
=√2 i + 3√2 i
=4√2 i
Hope this helps!! :)

Consider
the linear function f(x) = mx + b, where m = 0, on the interval [3, 7). Explain
why the maximum value of the function over this interval must occur at one
of the endpoints of the interval.
Answer:
Assuming that m does not = 0, then the function has a non horizontal slope, so the value will increase as the position moves away from zero in either the negative or positive direction depending on whether the slope (m) is negative or positive. The furthest that the position can be from 0 is at one of the endpoints of the interval [3, 7), therefore, the maximum value of the function on the same interval must be at one of the endpoints.

Step-by-step explanation:
Given:
cos²27°×cos²34°×...×cos²167 = ?Looking at the angles measures, they form series of:
27, 34, 41, ..., 167This is AP with the first term of 27 and common difference of 7
We can see one of the terms of this AP is 90
27+9*7 = 27 + 63 = 90Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.
So correct answer choice is Option 4) 0
what is the quotient of
[tex]2 \frac{2}{7} \div \frac{4}{7} [/tex]
[tex]2 \frac{2}{7}[/tex] ÷ [tex]\frac{4}{7}[/tex]
First, let's turn the first fraction into an improper fraction.
[tex]\frac{16}{7}[/tex] ÷ [tex]\frac{4}{7}[/tex]
Since both of these fractions share the same denominator, we can drop the denominator and simply divide the numerators.
16 ÷ 4 = 4
The quotient = 4

The sum of 2 consecutive odd integers is 204. What are the two odd integers?
101 and 104 i think is the most easy answer
Answer:
101, 103
Step-by-step explanation:
Say n is the first odd integer. The sum of n and its consecutive integer can be written as n + (n + 2). Doing some simple algebra:
n + (n+2) =204
2n + 2 = 204
2n = 202
n = 101
n is 101, and its consecutive integer, (n+2), is 103.

26 ft 10 ft , what is the height of the flagpole ?
The height of the flagpole is: 12 ft.
What is pythagorous theorem?A theorem attributed to Pythagoras that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
Let the height of the flagpole be: x ft.
Now, we can model this problem with the help of a right angled triangle such that the hypotenuse of the triangle is: 20 feet
and one of the leg of the right triangle is: 16 feet
Now, in order to find the other leg i.e. x we need to use the Pythagorean Theorem.
[tex]20^2=x^2+16^2\\\\\\400=x^2+256\\\\\\x^2=400-256\\\\\\x^2=144\\\\\\x=\pm12[/tex]
i.e.
But the height can't be negative.
Hence, we get: x=12

Step-by-step explanation:
GK = 24, HJ = 10, and GH = HI = IJ. Find each length.
Greetings from Brasil....
Let us call X the equal distances GH = HI = IJ
GH = X
HI = X
IJ = X
Note that HJ = HI + IJ, so
HJ = X + X
10 = 2X
X = 5
Looking at the figure we can conclude that:
GJ + JK = GK
GJ = GH + HI + IJ
GJ = 15
GJ + JK = GK
15 + JK = 24
JK = 9
GH = X = 5HI = X = 5IJ = X = 5JK = 9Each length of the line segments GH = HI = IK and JK will be 5 and 9.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries.
A line segment is sometimes referred to as a section of a path that joins two places.
GK = 24, HJ = 10, and GH = HI = IJ.
Then the length HI will be
HJ = HI + IJ
10 = HI + HI
2HI = 10
HI = 5
Then the length of the line segments GH, HI, and IJ will be
GH = HI = IJ = 5
The length of the JK will be
GK = GJ + JK
24 = 3GH + JK
24 = 3 * 5 + JK
JK = 24 - 15
JK = 9
Then each length of the line segments GH = HI = IK and JK will be 5 and 9.
