Step-by-step explanation: Range is the differance between the highest an lowest number, therefor you would use the highest number, 13 minus the lowest number witch is 2, so 13-2 is 11
Answer: 11
The range is the difference between the highest number and the lowest number
13 - 2 = 11 :)
He also has a piece of string that is 214214 ft long. Olivier needs to cut this string into 3 pieces that are all the same length to finish an art project. How long should each piece of string be?
Answer:
71.3 ft
Step-by-step explanation:
Oliver has a piece of string that is 214 ft long. He needs to cut this string into 3 pieces that are all the same length.
To find the length that each piece should be, we divide the length of the string by 3:
214 / 3 = 71.3 ft
Each piece should be 71.3 feet long.

Which equation has no solution?
Answer:
B. 5 + 2(3+2x) = x + 3(x+1)
Step-by-step explanation:
5 + 2(3+2x) = x + 3(x+1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
4x - 4x = 3 - 11
0 = - 8, which is absurd.
Hence the equation 5 + 2(3+2x) = x + 3(x+1) has no solution.
Ed is constructing the perpendicular bisector of a segment on his paper. He just finished
labeling the points of intersection of the two arcs that he drew. What is his next step?
Answer:
The next step is to draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
The line drawn in the above step, from the two labelled points is the perpendicular bisector of the segment
Step-by-step explanation:
To draw a perpendicular bisector of a segment, we have;
1. Ensure the compass is opened to more than half of the length of the segment to be bisected
2. Draw arcs of the same radius with center at the ends of the line to be bisected
3. Label the points where the arcs drawn from both ends cross each other on opposite sides of the line
4. Draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
5. The line so drawn from the two labelled points is the perpendicular bisector of the segment.

The cost of 24 bottles of water is $6. How much does it cost for 10 bottles of water?
Find the unit rate: 24 water bottles ÷ 6 dollars total = $0.25 a water bottle
Next, take the rate per water bottle and multiply it by ten: $0.25 a water bottle x 10 bottles of water = $2.50 total
So, this gives you your final answer. Ten bottles of water cost you $2.50!
Put these in order of size from smallest to largest: 7/4 , 74% , 7.4 , 4/7 , 70.4
Two solutions of salt water contain 0.06% and 0.21% salt respectively. A lab technician wants to make 1 liter of solution which contains 0.12% salt. How much of each solution should she use?
Answer:
The first solution must have 0.6 l and the second one 0.4 l.
Step-by-step explanation:
The volume of the first solution will be called "x", while the one from the second will be "y". The salt content on the first solution is "0.0006*x", while the salt content on the second solution is "0.0021*y", and the sum of these two values must be the same as the one in the final solution, so we have:
0.0006*x + 0.0021*y = 0.0012
And the sum of volumes must be equal to 1 liter.
x + y = 1
We have the equation system:
x + y = 1 (1)
0.0006*x + 0.0021*y = 0.0012 (2)
Isolating the "x" variable in the first equation and applying it in the second we have:
x = 1 - y
0.0006*(1-y) + 0.0021*y = 0.0012
0.0006 - 0.0006*y + 0.0021*y = 0.0012
0.0015*y = 0.0006
y = 0.0006/0.0015 = 0.4
x = 1 - 0.4 = 0.6
The first solution must have 0.6 l and the second one 0.4 l.

The required factor form of the polynomial equation x²-12x+36 is (x-6)².
Option A is correct.
The factored form of the polynomial x² − 12x + 36 equation is to determined.
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Here, The given polynomial function f(x) = x²− 12x + 36
Factorization of a given polynomial function,
f(x) = x²− 12x + 36
spitting 12x in 6x+ 6x
f(x) = x²− 6x-6x + 36
taking commons
f(x) = x(x− 6)-6(x - 6)
f(x) = (x− 6)(x - 6)
f(x) = (x− 6)² is the factorized form of f(x) = x²− 12x + 36.
Thus, The required factor form of the polynomial equation x²-12x+36 is (x-6)².

En 16 días se consume 1/8 de la carga de una batería. ¿Cuantos se consumirá en 48 días?
Answer: 3/8
Step-by-step explanation:
1/8 of the charge of a battery is consumed in 16 days. How will be consumed in 48 days?
So, to answer this question we simple have to apply a proportion:
(1/8 )/16 = charge consumed /days
For 48 days= x /48 days
(1/8 )/16 = x/48
Solving for x (charge)
[(1/8 )/16] 48 = x
3/8 =x

A square fits exactly inside a circle with each of its vertices being on the circumference of the circle.
The square has sides of length x cm.
The area of the circle is 56cm squared.
Work out value of x.
Give answer correct to 3 significant figures.
Answer:
The side of the square is 5.971 cm
Step-by-step explanation:
If the square fits the circle exactly, then its diagonal is equal to the diameter of the circle. Since the side of the square has a length of [tex]x[/tex] cm, then it's diagonal have the length of [tex]x\sqrt2[/tex] cm. Using the circle's area we can find the diagonal of the square, as shown below:
[tex]area = \pi*r^2\\56 = pi*r^2\\r^2 = \frac{56}{\pi}\\r = \sqrt{\frac{56}{\pi}}\\r = 4.222[/tex]
Since the diameter of the circle is the same as the diagonal of the square, then:
[tex]x\sqrt{2} = 2*r \\x = \frac{2*r}{\sqrt{2}}\\x = \frac{2*4.222}{\sqrt{2}}\\x = 5.971[/tex]
The side of the square is 5.971 cm

which describes the slope of this line?
I believe the the answer is zero.
Which line on the graph below has a slope of zero? On a coordinate plane, line Q is horizontal, line P has a positive slope, line R is vertical, and line S has a negative slope.
Answer:
line q because it just is
Step-by-step explanation:
The line that has zero slope is horizontal in the coordinate plane. the correct option is (a).
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference. The negative slope indicates the rate of decrease while the positive shows the rate of increase.
The given options can be analysed one by one as follows,
(a) A horizontal line on a coordinate plane is parallel to x axis.
The angle the line makes with x axis is zero which implies the slope is also zero.
(b)The line in the given case has some positive value of slope.
(c) A vertical line makes right angle with x axis.
Thus, the slope is tan(90°) = ∞,.
(d) The line in the given case has some negative value of slope.
Hence, the horizontal line will have zero slope.

what is the answer for this in square root form
Answer:
x = ± sqrt(-49)
or x = ± 7i
Step-by-step explanation:
x^2 +49 = 0
Subtract 49 from each side
x^2 +49 -49 = 0-49
x^2 = -49
Take the square root of each side
sqrt(x^2) = ± sqrt(-49)
x = ± sqrt(-49)
We have to complex numbers to solve
x = ± sqrt(-1) sqrt(49)
sqrt(-1) = i
x = ±i *7
x = ± 7i

Answer:
Step-by-step explanation:
7
Answer:
≈ 7
Step-by-step explanation:
the formula of the volume of a cylinder is:
V = π r^2 * h
792 = 3.14 * 6^2 *h
so first divide by 6^2 (or 36) on both sides so you can start to isolate h
36/36 = 1 and 792/36 = 22
22 = 3.14 *h
now divide by 3.14 to get h by itself
3.14/3.14 = 1 and 22/3.14 ≈ 7
the answer is approximately 7 and precisely 7.002817496
