Answer:
4Step-by-step explanation:
For the given set, {1x∣∣∣x∈ℤ and 2≤x≤5}, x∈ℤ means that the elements of the set are integers and 2≤x≤5 means the integers are values from 2 to 5.
Note that integers are whole numbers. The integers from 2 to 5 are 2, 3, 4 and. 2 and 5 are included to due the equality sign present in the inequality.
The elements of the set are {2, 3, 4, 5}.
Cardinal number of the set is similar to cardinality of the set. In set theory, cardinality of a set is the total number of element in the set. According to the set above, the total number of element in the set is 4.
Hence the cardinal number of the set is 4

robert has a piece of rope 12 1/2 feet long. he cut rope into pieces that are 1 1/4 feet long. How many of the shorter pieces will he have?
Answer:
divide 25.5 by 6
or change them to fractions
51/2 divided by 6 = 51/2 x 1/6 = 51/12 = 4 3/12 = 4 1/2 feet each
Step-by-step explanation:
Answer:
He will have 10 shorter pieces
To find this, divide 12.5 from 1.25
To check your answer, multiply the answer, 10, by 1.25 and you should get 12.5.

The equation |x|=a has no solution if a is a negative number. (1 point) A. The statement is false. The equation |x|=a has one solution if a is a positive number. B. The statement is false. The equation |x|=a has one solution if a is a negative number. C. The statement is false. The equation |x|=a has no solution if a is a positive number. D. The statement is true.
Answer:
The statement is false. The equation |x|=a has one solution if a is a negative number.Step-by-step explanation:
Given the expression |x|=a, we must understand that |x| can return both positive and negative value of x i.e
x=a and -x = a
from the second equation,
-x = a
multiply both sides by minus
-(-x) = a
x = -a
Hence If "a" is negative number according to the question then the equation has one solution which renders the fact that the equation has no solution if a is negative false.

Class Scheduling Enormous State University's Math Department offers two courses: Finite Math and Applied Calculus. Each section of Finite Math has 80 students, and each section of Applied Calculus has 70 students. The department will offer a total of 150 sections in a semester, and 11,200 students would like to take a math course. How many sections of each course should the department offer in order to fill all sections and accommodate all of the students
Answer:
70 section of Finite math and 80 section of Applied calculus
Step-by-step explanation:
As in each section, finite math has 80 student and applied calculus has 70 students
80x + 70Y = 11,200................(i)
There are 150 sections in a semester
x + y = 150..................................(ii)
Multiply equation (ii) by -70
-70x - 70y = 10,500
Add equation (i) and equation (iii)
80x + 70Y = 11,200
-70x - 70y = 10,500
10x = 700
x = 700/100
x= 70
Substitute x in equation (ii)
x + y = 150
70 + y = 150
y = 150 - 70
y = 80
Hence, 70 section of finite math and 80 section of applied calculus should the department offer in order to fill all sections and accommodate all of the students.

Explain what SOHCAHTOA means.
Answer:
It's a mnemonic device to help you remember the three basic trig ratios used to solve for missing sides and angles in a right triangle. It's defined as: SOH: Sin(θ) = Opposite / Hypotenuse. CAH: Cos(θ) = Adjacent / Hypotenuse.
Answer:
SOH CAH TOA is a mathmatical acronym used in triginometry. It helps find missing angels and sides of a triangle.
Step-by-step explanation:
Sine = Opposite side over Hypotenuse ---> SOH
Cosine = Adjacent side over Hypotenuse ---> CAH
Tangent = Opposite side over Adjactent ---> TOA
You use SOHCAHTOA to find the angle. You use the inverses to find the measures.

Answer:
Positive; P increases
Step-by-step explanation:
When gasoline prices go up, the demand for push lawn mowers increases, so the sign of the cross-elasticity is positive.
If gasoline prices go up, and demand for push lawn mowers goes up, then the price for push lawn mowers will also go up.
solve for b
A=h(a+b)2
Answer:
B = (A/(2h)) - a
Step-by-step explanation:
A = h(a+b)2
divide both sides of the equation by 2h
A/(2h) = a+b
subtract a from both sides
(A/(2h)) -a = b

Mmars= 6.42 x 10^23kg, RMars
3397 km)
Calculate the acceleration of gravity on the surface of Mars
Express your answer with the appropriate units.
Given :
Los Angeles and Las Vegas.
Mass of Mars , [tex]M=6.42\times 10^{23}\ kg[/tex].
Radius of Mars ,
[tex]R=3397\ km\\\\R = 3.397\times 10^6\ m[/tex]
To Find :
The acceleration of gravity on the surface of Mars.
Solution :
Acceleration due to gravity is given by :
[tex]g_m = \dfrac{GM_m}{R_m^2}\\\\g_m =\dfrac{(6.67\times 10 ^{-11}\ m^3\ kg^{-1}\ s^{-2})(6.42\times 10^{23}\ kg) }{(3.397\times 10^6\ m)^2}\\\\g_m = 3.71\ m/s^2[/tex]
Therefore, the acceleration of gravity on the surface of Mars is 3.71 m/s².
Hence, this is the required solution.
Lauren would like to find the midpoint of a line segment that has endpoints at (–0.5, 3) and (4, 7.5). Which statements are true? Check all that apply. Lauren could solve to find the x-coordinate. Lauren could solve to find the y-coordinate. Lauren could solve (4 + 0.5) – 0.5 to find the x-coordinate. Lauren could solve (7.5 + 3) + 3 to find the y-coordinate. Finding the midpoint is equivalent to partitioning a line segment in a 1:1 ratio.
