(change the operation to multiplication)
[tex]\frac{20}{1}[/tex] × [tex]\frac{16}{15}[/tex] = [tex]\frac{320}{15\\}[/tex] (multiply, then reduce)
64/3 ⇒ 64/3
The value of x in the expression 20 divided by 15/16 will be 21.33 .
Given , 20 divided by 15/16
Division property:
The rules for division are:
(1) positive ÷ positive = positive
(2) positive ÷ negative = negative
(3) negative or ÷ negative = positive
Here both the numbers are positive. Apply rule 1.
20 divided by 15/16

An experiment involving learning in animals requires placing white mice and rabbits
into separate, controlled environments, the environment I and environment II.
The maximum amount of time available in the environment I is 500 minutes, and the maximum
amount of time available in environment II is 600 minutes.
The white mice must spend 10 minutes in environment I and 25 minutes in environment II, and
the rabbits must spend 15 minutes in environment I and 15 minutes in environment II. Identify which set of constraints and objective function is correct? x=white mice and y=rabbits

1 triangle ABC was dilated by a scale factor of 2 centered at the origin of the result was as image of triangle A'B'C shown on the coordinate plane below the vertices of triangle A'b'c' are -4,4 -4,6 and 2,4 what are the coordinates of the vertices ABC
Answer:
The coordinates of ABC are respectively (-2,2), (-2,3), and (1,2).
Step-by-step explanation:
Dilation About the Origin
Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).
If we are given the dilated point, then we can find the original point by dividing by the scale factor.
Triangle ABC was dilated by a scale factor of 2 about the origin mapping it to triangle A'B'C' with vertices A'(-4,4), B'(-4,6), and C(2,4).
The coordinates of triangle ABC are:
A=(-4/2,4/2) = (-2,2)
B=(-4/2,6/2) = (-2,3)
C=(2/2,4/2) = (1,2)
The coordinates of ABC are respectively (-2,2), (-2,3), and (1,2).
Answer:
The coordinates of ABC are (-2,2), (-2,3), and (1,2).

A parking lot has 27 empty spaces. If the ratio of empty spaces to taken spaces is 3:5, how many spaces are there total?
Answer:
There are 72 spaces
Step-by-step explanation:
You would first have to do 27/3, which shows what 1/5 is. This would get you 9, then multiply that by 5 to find the amount of taken spaces. Add 27 and 45 to get 72 spaces.
Answer:
72 spaces in total
Step-by-step explanation:
If there are 27 empty spaces in a 3:5 ratio, that means that for every 3 spaces that are empty, there are 5 that are taken. We notice that there are 9 times of 3 spaces that are empty, so we must multiply 9 by 5 to get 45 spaces that are taken. We then add these up to get the total amount of spaces 27 + 45 = 72 spaces

Answer:
5) 1
6) 131
Step-by-step explanation:
5)
f(1) = -1 - 8 = -9
-9 + 10 = 1
6)
g(-9) = [tex]9^{2}[/tex] + 8(9) - 15 = 138
138 - 7 = 131
Answer:
Step-by-step explanation:
5.
f(x) = -x -8
substitute x with 1 in the equation of f(x)
f(1) +10 = -1 -8 +10 = -9 +10 = 1

What is the perimeter of a triangle if two of its sides measure 6 in. and the other side
measures 7 in. ?
The perimeter of the triangle if its two sides measure 6 inches and the other side measures 7 inches will be 19 inches.
According to the given question.
The measure of the two sides of a triange is 6inches each.
And the measure of the other side is 7 inches.
As we know that,a perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length or the perimeter of a shape is defined as the total length of its boundary.
Thereofre, the perimeter of the triangle if its two sides measure 6 inches and the other side measures 7 inches
= 6 inches + 6 inches + 7 inches
= 19 inches
Hence, the perimeter of the triangle if its two sides measure 6 inches and the other side measures 7 inches will be 19 inches.

Use the given information to find the minimum sample size required to estimate an unknown population mean mu. How many students must be randomly selected to estimate the mean weekly earnings of students at one college? We want 95% confidence that the sample mean is within $2 of the population mean, and the population standard deviation is known to be $99.
A) 8296
B) 6630
C) 9413
D) 13,302
Answer:
9413
Step-by-step explanation:
Given that :
Error = $2 ; Standard deviation (σ) =99 ; α = 95% = 0.95
Zα/2 = Z0. 05/2 = 1.96 (Z probability calculator)...
n = sample size
Recall:
n = ((Zα/2 * σ) / Error)^2
Using the formular above, the sample size n can be obtained ;
n = ((1.96 * 99) / 2)^2
n = 97.02^2
n = 9412.8804
n = 9413
The odds against Ishaq getting hired for a job are 17:18. Determine the probability
(a) Ishaq gets hired.
(b) Ishaq does not get hired.
Answer:
The odds against Ishaq getting hired are 17:18
This means that are 17 scenarios where Ishaq does not get hired, out of 18 total scenarios.
This means that the left scenario is when Ishaq gets hired, then the odds of Ishaq getting hired is equal to 1:18.
a) We want to find the probability that Ishaq gets hired.
This will be equal to the quotient between the number of scenarios where Ishaq gets hired (1) and the total number of scenarios (18).
Then this probability is
P = 1/18 = 0.056
b) We want to find the probability where Ishaq does not get hired, we can use the same reasoning as above, this time we will take the quotient between the number of scenarios where Ishaq does not get hired (17) and the total number of scenarios (18).
P = 17/18 = 0.944

-5 multiplicity 2
-2 multiplicity 1
Answer:
[tex]P(x)=x^3+12x^2+45x+50[/tex]
Step-by-step explanation:
Roots of a polynomial
If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula
[tex]P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)[/tex]
Where a is an arbitrary constant.
We are given the following roots:
-5 multiplicity 2 (-5 twice)
-2 multiplicity 1
Thus, the polynomial is:
[tex]P(x)=a(x-(-5))(x-(-5))(x-(-2))[/tex]
[tex]P(x)=a(x+5)(x+5)(x+2)[/tex]
We are not given any clue about the value of a, so we choose a=1. Multiplying:
[tex]P(x)=(x^2+5x+5x+25)(x+2)=(x^2+10x+25)(x+2)[/tex]
[tex]P(x)=x^3+2x^2+10x^2+20x+25x+50[/tex]
Simplifying:
[tex]\mathbf{P(x)=x^3+12x^2+45x+50}[/tex]

a. 68
b. 44
c. 56
d. 22
Answer: x=68° because this triangle is a isoscele triangle which means that it haves 2 sides that are congruent and equivalent which means they have the same value and sides and are Congruent just means In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
The value of angle [x] is equivalent to 44°.
What is Parallelogram? What is triangle? What is a expression? What is a mathematical equation?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.We have a triangle as shown.
We know, the angles opposite to equal sides are equal.
So, we can write -
x + 68° + 68° = 180°
x = 180° - (136°)
x = 44°
Therefore, the value of angle [x] is equivalent to 44°.
