Answer: She read for 10 Days, equation below
Step-by-step explanation:
Number of pages = 180
Rate = 12pages Per day
Number of days read = (180-60) /12
Days read = (total no of page - page left)/page read per day
= 120/ 12 = 10 days
Days remaining = pages left /page per day
=60/ 12 = 5
Order the following numbers from least to greatest.
Help please
Answer:
[tex]2\frac{1}{3}[/tex], [tex]\sqrt{7}[/tex], [tex]\sqrt[3]{27}[/tex]
Step-by-step explanation:
If you want to make ordering these three numbers to be easier, it's best to find their exact or approximate values. [tex]\sqrt[3]{27}[/tex] is equivalent to 3, and [tex]\sqrt{7}[/tex] is less than [tex]\sqrt{9}[/tex] - which is 3 - so you know that [tex]\sqrt[3]{27}[/tex] is going to be the greatest number out of the set. Since [tex]\sqrt{7}[/tex] is approximately equal to 2.65, and [tex]2\frac{1}{3}[/tex] is approximately equal to 2.33, you can conclude that the correct order from least to greatest is going to be [tex]2\frac{1}{3}[/tex], [tex]\sqrt{7}[/tex], [tex]\sqrt[3]{27}[/tex].

find the length of each side of an equilateral triangle if the height is 10 in.
Answer:
20√3/3 or approx. 11.55 in.
Step-by-step explanation:
Draw an equilateral triangle with one height to one side.
The height divides the triangle into two congruent right triangles.
At the vertex where the height is, each angle of the small triangles is 30 deg.
The other acute angle of the right triangle measures 60 degrees.
The two right triangles are 30-60-90 right triangles.
The ratio of the lengths of the sides of a 30-60-90 right triangle is
1 : √3 : 2
The height is opposite the 60-deg angle, so it corresponds to the side with length √3 in the ratio.
The long leg measures 10.
The short leg measures 10/√3 = 10√3/3
The hypotenuse measures 20√3/3
The side of the equilateral triangle is the hypotenuse of each small right triangle.
Answer: 20√3/3 or approx. 11.55 in.
please fill in the venn diagram and answer the question below. thanks!!!
Step-by-step explanation:
you understand how a venn diagram works ?
you have to put elements or the amount of elements into the different segments. there are segments that belong to only one category, segments with elements that are shared between 2 neighboring categories, and in this case 1 segment in the middle that has all elements shared between all 3 categories.
so, we know, the total of all elements (fans) is 36.
now imagine we place every fan exactly into the segment, where his or her allegiance lies.
the easiest way to start is with the center. there are 5 fans there, so write 5 in there.
these 5 people are therefore also part of the total number of Wild fans, of the Viking fans and the Twins fans, and of all the shared segments, of course.
so, we have only 7-5 = 2 shared Wild and Vikings only fans (in the segment above the center segment). they are not fans of the Twins.
we have 9-5 = 4 shared Wild and Twins only fans (in the segment left below the center). they are not fans of the Vikings.
we have 11-5 = 6 shared Vikings and Twins only fans (in the segment right below the center). they are not Wild fans.
what is left for the pure, single team fans ?
the Wild have 12-5-2-4 = 1 pure fan.
the Vikings have 16-5-2-6 = 3 pure fans.
the Twins have 22-5-4-6 = 7 pure fans.
so, we have 1+3+7 = 11 pure fans, 2+4+6 = 12 double team fans, and 5 all 3 teams fans. but that is only 28 fans altogether.
so, something is not right with the data here.
I assume we have 28 total from now on.
for Viking AND Wild fans we have the 2 fans that only like these 2 teams plus the 5 that like all 3 teams (including the Vikings and the Wild) = 7 out of the total of 28 fans.
the probability to pick one of them is then
7/28 = 1/4 =0.25
if the total of 36 questioned fans is still there and explained maybe outside of the given venn diagram (e.g. were asked but are fans of a totally different team or of no team at all), then the probability would be
7/36 = 0.194444444...

ABCD is a rhombus. The coordinates of A are (5, 11) The equation of the diagonal DB is y = 3x + 5 The equation of the diagonal AC can be written in the form y = mx + Ċ where m and c are integers. Work out the value of m and the value of c.
Applying the definition of the diagonals of a rhombus, the value of m is -3, and the value of c is 26.
What are the Diagonals of a Rhombus?The diagonals of a rhombus are perpendicular to each other and therefore have slopes that are negative reciprocals.
Equation of diagonal DB is, y = 1/3x + 5.
Slope (m) of DB is 1/3.
Therefore, the slope (m) of diagonal AC would be, -3.
To find the equation of diagonal AC, substitute m = -3 and (5, 11) = (a, b) into y - b = m(x - a)
y - 11 = -3(x - 5)
y - 11 = -3x + 15
y = -3x + 15 + 11
y = -3x + 26
m = -3; c = 26

The equation, in slope-intercept form, of the line that is parallel to the given line and passes through the point (0, 12) is y = -5x + 1
Equation of a lineA line is the distance between two points
Given the equation of a line expressed as 10x + 2y = -2. Determine the slope
2y = -10x -2
y = -5x - 1
Slope of the line is -5
The equation of a line in point-slope form is y - y1 = m(x-x1)

5x−2(x+1)=1/4 find x pretty please
Answer:
Delaney solve for X by isolating it, or getting it by it self
Step-by-step explanation:
5x−2(x+1)=1/4 (distribute the 2)
5x-2x - 2 = 1/4 (subtract 2x from 5x)
3x -2 +2 = 1/4 +2 (add 2 to both sides)
3x = 2_1/4 (put 2 & 1/4 together)
3x = 9/4 (convert 2_1/4 to 9/4)
[tex]\frac{1}{3}[/tex]*3*x = [tex]\frac{1}{3}[/tex]*[tex]\frac{9}{4}[/tex] ( mutilply both sides by 1/3)
X = 3/4 (cross multiply )
There you go
X = [tex]\frac{3}{4}[/tex]
Answer:
[tex]\huge\boxed{\bf\:x = \frac{3}{4}}[/tex]
Step-by-step explanation:
[tex]5x - 2(x+1)=\frac{1}{4}[/tex]
Use the distributive property for 2(x + 1).
[tex]5x - 2x - 2= \frac{1}{4}[/tex]
Subtract 2x from 5x.
[tex]3x - 2= \frac{1}{4}[/tex]
Bring 2 to the right hand side of the equation .
[tex]3x = \frac{1}{4} + 2[/tex]
Add 1/4 & 2.
[tex]3x = \frac{1}{4} + \frac{8}{4} \: \: [LCM = 4]\\3x = \frac{9}{4}[/tex]
Now, bring 3 to the right hand side of the equation .
[tex]x = \frac{9}{4} \times \frac{1}{3}\\x = \frac{9}{12}\\\boxed{\bf\:x = \frac{3}{4}}[/tex]

Answer:
cos theta = 5/13
Step-by-step explanation:
sin theta = opp side / hypotenuse
opp side = 12 and hypotenuse = 13
Using the pythgorean theorem
opp ^2 + adj ^2 = hypotenuse ^2
12 ^2 + adj^2 = 13^2
144 + adj ^2 = 169
adj^2 = 169-144
adj^2 = 25
Taking the square root of each side
adj = 5
cos theta = adj / hypotenuse
cos theta = 5/13
EXPLAIN the difference between theoretical and experimental probability. Use an example.
Step-by-step explanation:
Theoretical probability describes how likely an event is to occur. We know that a coin is equally likely to land heads or tails, so the theoretical probability of getting heads is 1/2. Experimental probability describes how frequently an event actually occurred in an experiment.
EXAMPLE-
Theoretical probability:
For instance, since a flipped coin has two sides and each side is equally likely to land up, the theoretical probability of landing heads (or tails) is exactly 1 out of 2.
Experimental probability:-
For example, the probability of getting a head if you flip a coin is ½, since only 2 things could happen (a head or a tail) and each one has an equal chance of occurring.

The sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
As we know, the sample size can be evaluated using the expression:

or
[tex]\rm n = \dfrac{Z^2}{ME^2}(pq)[/tex]
Here ME = 1% = 0.01
