Answer:
your mixed fraction would be 12 37/100
Step-by-step explanation:
The number has two parts the whole number part is 12, and the decimal part is .37, 12 would be the whole number part of your mixed fraction and we will convert the .37 to become the fraction part of your mixed fraction.
You have to convert the decimal part into a fraction since there are two decimal places you will have 100 in the denominator .37 becomes 37/100 simplify this fraction if possible.
find x for 14x+17=2(x+3)^2-5
The values of x will be 2 and -1.
Given that:-
[tex]14x+17=2(x+3)^2-5[/tex]
We have to find the value of x.
As it is a quadratic equation, there will be two values of x.
Opening the bracket and solving the equation further, we get,
[tex]14x+17=2(x^2+9+6x) -5\\14x+17 = 2x^2 +18+12x-5\\2x^2-2x-4 = 0\\2(x^2-x-2) =0\\x^2-x-2 = 0[/tex]
Using middle-term split theorem to solve the quadratic equation, we get,
[tex]x^2-x-2 = 0\\x^2+x-2x-2=0\\[/tex]
x(x + 1) - 2(x + 1) = 0
(x + 1)(x - 2) = 0
Hence, either x + 1 = 0 or x - 2 = 0 or both of them are 0.
x + 1 = 0
x = -1
and,
x - 2 = 0
x = 2
Hence, the values of x are 2 and -1.

Students were polled regarding their favorite sport. The results are shown in the bar graph. Create a circle graph from the data in the bar graph.
The circle graph/pie chart is made for the given bar graph.
What is defined as the circle graph/pie chart?A pie chart is a type of graph that displays data in a circular graph. The slices of pie represent the relative amount of information and are a type of pictorial data representation.
A pie chart necessitates a list of categorical and numerical variables. The term "pie" refers to the whole, and "slices" refer to the parts of the total.The "pie chart" or "circle chart" divides the circular statistical graphic in to the sectors or sections to illustrate numerical problems. Each sector represents a proportionate portion of the total.The Pie-chart works best for determining the composition of an object at that time.Now, as the data given in the bar graph.
The basketball is played the number of students is 4.
That is 40% of the total.
The football is played the number of students is 3.
That is 30% of the total.
The baseball is played the number of students is 2.
That is 20% of the total.
The soccer is played the number of students is 1.
That is 10% of the total.

research suggests that people who work in business and professional settings spend 26% of their time speaking, compared to 23% writing, and 19% reading. what percentage do those same people spend listening?
32% of the same people spend their time listening.
The total number of mentioned people will be 100% or 1. Now, in the total people, the remaining ones who are not stated in the question, must be the listeners. Thus, calculating the remaining percentage of people, we will get the percentage of listeners in same people.
So, number of people who spend time speaking = 26%
Number of people who spend time speaking = [tex]\frac{26}{100}[/tex]
Number of people who spend time speaking = 0.26
Number of people who spend time writing = 23%
Number of people who spend time writing = [tex]\frac{23}{100}[/tex]
Number of people who spend time writing = 0.23
Number of people who spend time reading = 19%
Number of people who spend time reading = [tex]\frac{19}{100}[/tex]
Number of people who spend time reading = 0.19
Total number of people involved in activities other than listening = 0.26 + 0.23 + 0.19
Total number of people involved in activities other than listening = 0.68
People who spend time listening = 1 - 0.68
People who spend time listening = 0.32
Percentage of people who spend time listening = 0.32 × 100
Percentage of people who spend time listening = 32%
Hence, 32% of the same people spend their time listening.

The coordinates of A and B are-7 and 9. The coordinates of C and D are -4 and 12. AB and CD are not congruent
What does it men to be congruent?
Congruent refers to objects that are precisely similar in size and shape. The forms stay equal no matter how they are rotated, flipped, or turned. For instance, create two circles with the same radius, cut them out, and stack them.
We'll see that they'll be placed entirely on top of one another and will superimpose one another. This demonstrates that the two circles are similar. Given that they have an equal radius and can be positioned exactly over one another, the circles below are considered to be congruent. "≅" is the sign used to represent the congruence of figures. Since circle A and circle B are similar, we may say the following: Circle B ≅ Circle A.
Lets assume AB and CD are congruent
Then according to Pythagoras theorem
Hypotenuse of AB of right-angled triangle AOB is equal to Hypotenuse of CD of right-angled triangle COD
Hypotenuse AB = Hypotenuse CD
Hypotenuse AB
a² + b² = c²
(-7)² + 9² = c²

Hypotenuse CD
a² + b² = c²
(-4)² + 12² = c²
16 + 144 = c²

IS this correct? im not sure
2 Answers:
Choice B) irrational
Choice F) Natural
=====================================================
Reason:
Let's go through the answer choices.
A) The value 0 is a real number. A real number is any thing you can think of such as 2/3 or [tex]\sqrt{93}[/tex] or 10.657 or 22, assuming your teacher hasn't covered imaginary or complex numbers. This rules out choice A.B) This is one of the answers. See choice C for further explanationC) The value 0 is rational since 0 = 0/1 is a fraction of two integers, where the denominator is nonzero. Since 0 is rational, it means it cannot be irrational. The term "irrational" means "not rational". Therefore, we can conclude that 0 is not in the set of irrational numbers. This is why choice B is one of the answers, and why we can rule out choice C.D) The set of integers is {...., -3, -2, -1, 0, 1, 2, 3, ...} which consists of positive and negative whole numbers. We also have 0 in this set. So choice D is ruled out. E) The set of whole numbers is {0, 1, 2, 3, 4, ...} which has 0 in it. We can rule out choice E.F) The set of natural numbers is very similar to the whole numbers, but one key difference: zero is missing. The natural numbers is {1, 2, 3, 4, ...} which shows that choice F is the other answerCaptain Ashley has a ship, the H.M.S Crimson Lynx. The ship is two furlongs from the dread pirate Umaima and her merciless band of thieves.
If her ship hasn't already been hit, Captain Ashley has probability 1/2 of hitting the pirate ship. If her ship has been hit, Captain Ashley will always miss.
If her ship hasn't already been hit, dread pirate Umaima has probability 1/3 of hitting the Captain's ship. If her ship has been hit, dread pirate Umaima will always miss.
If the Captain and the pirate each shoot once, and the pirate shoots first, what is the probability that both the pirate and the Captain hit each other's ships?
The probability would be zero that both the pirate and the captain hit each other's ships.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Captain Ashley has probability 1/2 of hitting the pirate ship.
Dread pirate Umaima has a 1/3 probability of attacking the Captain's ship if it hasn't already.
The captain must miss if the pirate hits, and the requirement that both hits are not satisfied. The requirement that both hits cannot be satisfied if the pirate misses.
Therefore, the probability would be zero that both the pirate and the Captain hit each other's ships.

[tex]-\sqrt{2}[/tex]Step-by-step explanation:
Make the following operations:
a² + b² = 6aba² + 2ab + b² = 8ab(a + b)² = 8aba + b = [tex]2\sqrt{2ab}[/tex]and
a² + b² = 6aba² - 2ab + b² = 4ab(a - b)² = 4aba - b = [tex]-2\sqrt{ab}[/tex], since a < bThe required value is:
[tex]\cfrac{a+b}{a-b} =\cfrac{2\sqrt{2ab} }{-2\sqrt{ab} } =-\sqrt{2}[/tex]Answer:
[tex]\dfrac{a+b}{a-b}=-\sqrt{2}[/tex]
Step-by-step explanation:
Given:
[tex]a^2+b^2=6ab[/tex]
[tex]0 < a < b[/tex]
Add 2ab to both sides of the given equation:
[tex]\implies a^2+b^2+2ab=6ab+2ab[/tex]
[tex]\implies a^2+2ab+b^2=8ab[/tex]
Factor the left side:
[tex]\implies (a+b)^2=8ab[/tex]
Subtract 2ab from both sides of the given equation:
[tex]\implies a^2+b^2-2ab=6ab-2ab[/tex]
[tex]\implies a^2-2ab+b^2=4ab[/tex]
Factor the left side:
[tex]\implies (a-b)^2=4ab[/tex]
Therefore:
[tex]\implies \dfrac{(a+b)^2}{(a-b)^2}=\dfrac{8ab}{4ab}[/tex]
[tex]\implies \dfrac{(a+b)^2}{(a-b)^2}=2[/tex]
[tex]\textsf{Apply exponent rule} \quad \dfrac{a^c}{b^c}=\left(\dfrac{a}{b}\right)^c:[/tex]
[tex]\implies \left(\dfrac{a+b}{a-b}\right)^2=2[/tex]
Square root both sides:
[tex]\implies \sqrt{\left(\dfrac{a+b}{a-b}\right)^2}=\sqrt{2}[/tex]
[tex]\implies \dfrac{a+b}{a-b}=\pm\sqrt{2}[/tex]
As 0 < a < b then:
a + b > 0a - b < 0Therefore:
[tex]\implies \dfrac{a+b}{a-b}=\dfrac{+}{-}=-[/tex]
So:
[tex]\implies \dfrac{a+b}{a-b}=-\sqrt{2}[/tex]

the span of a set of vectors is the set of all possible linear combinations of those vectors, and will always include the zero vector
The spam of the sets of vector of all linear combination is 0,
The span of the set {(2, 5, 3), (1, 1, 1)} is the subspace of R 3 consisting of all linear combinations of the vectors v 1 = (2, 5, 3) and,
v 2 = (1, 1, 1).
this defines a plane in R 3.
Since a normal vector to this plane in n = v 1 x v 2 = (2, 1, −3),
the equation of this plane has the form 2 x + y − 3 z = d for some constant d. the plane must contain the origin—it's a subspace— d must be 0.
A linear equation is an equation in which the highest power of the variable is always 1. it is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. A linear equation only has one or two variables.No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line

The mean waste recycled per person per day for the population of new- york is 1.9 < u < 2.3 .
Given that,
The mean waste recycled per person per day = 2.12
Standard Deviation = 0.250
c = 0.9 , So [tex]\alpha[/tex] =1-c =0.10
n = 9<30 so we use t critical value.
From t table we get the critical value = 1.859

So,
X = 2.1 , s = 0.25 , n= 9
2.1 - 1.86 (0.25/[tex]\sqrt{9}[/tex]) < u < 2.1 =1.86 (0.25/[tex]\sqrt{9}[/tex])

Using proportions, the amounts are given as follows:
Small: 24 Twix, 8 Milky Ways, 19 Snickers.Medium: 30 Twix, 10 Milky Ways, 25 Snickers.Large: 42 Twix, 14 Milky Ways, 37 Snickers.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
We have that the amount of Twix is triple the amount of Milky ways, hence:
In the small bag, there are 8 x 3 = 24 Twix.In the medium bag, there are 30/3 = 10 Milky Ways.There are 5 fewer Snickers then Twix, hence:
In the small bag, there are 24 - 5 = 19 Snickers.In the medium bag, there are 30 - 5 = 25 Snickers.In the large bag, there are 37 + 5 = 42 Twix and 42/3 = 14 Milky Ways.Hence the amounts are given as follows:
Small: 24 Twix, 8 Milky Ways, 19 Snickers.Medium: 30 Twix, 10 Milky Ways, 25 Snickers.Large: 42 Twix, 14 Milky Ways, 37 Snickers.More can be learned about proportions at https://brainly.com/question/24372153
