3x^34x^2-8x-5In a poll, 22% of 714 surveyed adults said that . What is the actual number of adults who said that
Answer:
157 surveyed adultStep-by-step explanation:
IF 22% of 714 surveyed adult made a statement, the actual number of those that made the statement can be gotten by simply evaluating 22% of 714 as shown below;
= 22% of 714
= 22/100 * 714
= (22*714)/100
= 15708/100
= 157.08
≈ 157 surveyed adult
This means that about 157 surveyed adults made the statement.

The map shows the route for a race.You are at X, 6000 ft from the first checkpoint C.The second checkpoint D is located at the midpoint between C and the end of the race Y.The total race is 3 miles how far apart are the 2 checkpoints? I know the answer is 4920 but i don’t know how to work it out
Answer:
Distance between the two check point (C and D) is 4920 ft.
Step-by-step explanation:
From the question given above, we obtained the following information:
X is 6000 ft from C (1st check point)
D (2nd check point) is the midpoint point between C and Y ( the end of the race)
Total race = 3 miles
1 mile = 5280 ft
Next, we shall express the total race in feet (ft).
This is illustrated below:
1 mile = 5280 ft
Therefore,
3 miles = 3 × 5280 = 15840 ft
Next, we shall determine the distance between the 1st check point (C) and the end of the race (Y)
This can be obtained as follow:
Total distance = 15840 ft
Distance between X and C = 6000 ft
Distance between C and Y =?
Distance between C and Y = (Total distance) – (Distance between X and C)
Distance between C and Y = 15840 – 6000
Distance between C and Y = 9840 ft
Finally, we shall determine the distance between the two check point (C and D) as follow:
Since D is midpoint between C and Y, therefore, we shall we shall divide the distance between C and Y by 2 in order to obtain the distance between the two check point (C and D).
This is illustrated below:
Distance between C and Y = 9840 ft
Distance between the two check point (C and D) = 9840/2 = 4920 ft
Therefore, the distance between the two check point (C and D) is 4920 ft

De la pregunta, la secuencia de imágenes, cuya expresión indica es 4 cadeiras, 6 cadeiras, 8 cadeiras ...
Se puede ver la secuencia una progresión aritmética de la forma 4, 6, 8 ... Para obtener la expresión que indica la cantidad de cadenas utilizadas o colocaremos n tablas una al lado de la otra, tendremos que encontrar el enésimo término de la secuencia que usa la fórmula para encontrar el enésimo término de una secuencia aritmética.
El enésimo término de un AP se expresa como Tₙ = a + (n-1) d donde;
a es el primer término
n es el número de términos es la diferencia común
De la secuencia generada, a = 4, d = 6-4 = 8-6 = 2
Tₙ = 4+ (n-1) 2
abre el paréntesis
Tₙ = 4 + 2n-2
Tₙ = 2n + 4-2
Tₙ = 2n + 2
Por lo tanto, la expresión que indica la cantidad de cadenas utilizadas o colocaremos n tablas una al lado de la otra es 2n + 2
Find three positive integers x, y, and z that satisfy the given conditions. The product is 125, and the sum is a minimum.
Answer:
Step-by-step explanation:
Given 3 positive integers x, y and z, if their product is 125, then;
xyz = 125 .......... 1
Sum of the integers S(x, y, z) = x+y+z ........... 2
From equation 1; x = 125/yz ........3
Substitute equation 3 into 2
S(x, y, z) = 125/yz+y+z
Sy = -125/y²z + 1
Sz = -125/z²y + 1
For the sum to be minimum, Sy = Sz = 0
-125/y²z + 1 = 0
-125/y²z = -1
-125 = -y²z
125 = y²z
Also; is Sz = 0
-125/z²y + 1 = 0
-125/z²y = -1
-125 = -z²y
125 = z²y
Hence y²z = z²y = 125
From y²z = 125, z = 125/y²
Substitute z = 125/y² into the equation 125 = z²y
125 = (125/y²)²× y
125 = 125²/y⁴ × y
125 = 125²/y³
1 = 125/y³
y³ = 125.
y = 5
Since 125 = y²z
5²z = 125
25z = 125
z = 5
From the product xyz = 125
x(5)(5) = 125
25x = 125.
x = 5
Hence x = y = z = 5

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
An air conditioning system can circulate 350 cubic feet of air per minute.
We know that 1 foot = (1/3) yards, then the 1 cubic foot = (1/27) cubic yards.
350 cubic feet / minute = (1/27) x 350 cubic yards / minute
350 cubic feet / minute = 12.96 cubic yards / minute
The amount of air in cubic yards per minute will be 12.96 cubic yards per minute.

Simplify 55/66 to lowest terms ?
Answer:
5/6
Step-by-step explanation:
To simplify this fraction, we need to find the GCF (greatest common factor) of the numerator and denominator. In this case, the GCF of 55 and 66 is 11. Now, all we have to do is divide both the numerator and denominator by the GCF. The numerator will become 55 / 11 = 5 and the denominator will become 66 / 11 = 6 so the simplified fraction is 5 / 6.

The width of a rectangle is 4 inches (in) and the area of the rectangle is 32 in2? Which of the following represents the length of the rectange?
a. 8 in
b. 128 in
c. 28 in
d. 36 in
Answer:
A. 8
Step-by-step explanation:
32 divided by 4 = 8
The answer is a. 8 in.
Since the width of the rectangle is 4 inches (in) and the area of the rectangle is 32 in², we need to find the length of the rectangle.
We know that the area of a rectangle with length, L and width, W is A = LW.
Since we need to find the length of the rectangle, we make the length, L subject of the formula.
Since A = LW,
L = A/W
Given that A = 32 in² and W = 4 in
Substituting the values of the variables into the equation, we have
L = 32 in²/4 in
L = 8 in
So, the length of the rectangle is 8 in
So, the answer is a. 8 in.

What is the equation of the slant asymptote of the rational function? f(x)=6x3−15x2+x−43x2−1 y=x−5 y=2x−5 y=x−17/3 y=2x−17/3
Answer:
2x − 5
Step-by-step explanation:
To solve, divide the numerator by the denominator. The result (not including the remainder) will be the equation of the slant asymptote.
We can tell the first term of the quotient will be 2x, so the answer will be either 2x − 5 or 2x − 17/3.
The easiest method here is to simply multiply these by denominator.
(3x² − 1) (2x − 5) = 6x³ − 15x² − 2x + 5
(3x² − 1) (2x − 17/3) = 6x³ − 17x² − 2x + 17/3
So the answer must be 2x − 5.
Alternatively, you can use long division.
Answer:
2x-5
Step-by-step explanation:
f(x)=(6x^3−15x^2+x−4 )/(3x^2−1)
To find the slant asymptote,divide the numerator by the denominator
2x +(-15x^2+3x-4)/ (3x^2-1)
-5 + (3x-9)/(3x^2-1)
The divisor is (2x-5) and the remainder is ( 3x-9)

5(x - 10) = 30 - 15x
Answer:
x = 4
Step-by-step explanation:
We can first expand 5(x-10), getting 5x - 50.
Thus, 5x - 50 = 30 - 15x
We can then isolate x, getting (5+15) x = 30 + 50
20 x = 80
x = 4.
Answer:
5(x - 10) = 30 - 15x
We distribute 5 (x-10)
So 5x-50 = 30 -15x
5x+15x=50+30
(-15x became 15x because we brought it back to the other side and -50 became 50 because we brought it back to the other side to put the x's with the x's and the digits with the digits.)
So 20x=80
x= 50/20
We simplify 80/20
So x=4

Fifty part-time students were asked how many courses they were taking this term. The incomplete) results are shown below.
Part (b)
What percent of students take exactly two courses?
Part (c)
What percent of students take one or two courses?
%
Answer:
There are 50 part-time students:
15 of them, take only one course.
10 of them, take only two courses.
then the rest, this is:
50 - 10 - 15 = 25
25 students take 3 courses.
b) What percent of students take exactly two courses?
15 out of 50 take exactly two courses, the percentage is:
p = (10/50)*100% = 20%.
c) What percent of students take one or two courses?
This will be the percentage of students that take only one course plus the percentage of students that take two courses:
The percentage of students that take two courses is already known: 20%.
Now, for 1 course we have 15 students out of 50, the percentage is:
p = (15/50)*100% = 30%.
Then the percentage that take 1 or 2 courses is:
P = 30% + 20% = 50%
20% of students take exactly two courses, and 50% of students take one or two courses.
Given that fifty part-time students were asked how many courses they were taking this term, of which 15 take only 1 course, while 10 take 2 courses, to determine what percent of students take exactly two courses, and what percent of students take one or two courses, the following calculation must be performed:
(10/50) x 100 = X 0.2 x 100 = X 20 = X
(25/50) x 100 = X 0.5 x 100 = X 50 =X
Therefore, 20% of students take exactly two courses, and 50% of students take one or two courses.
