Step-by-step explanation:
the area of the base of a cone is 100sq. cm and it's height is 6cm. what is its volume
V=⅓πr²h
V=⅓*π*(100)²*6
V=188495.56
3
V=62831.85cm³
Answer:
600 cm2
Step-by-step explanation:
Area of base of cone (A) = 100 cm2
h = 6 cm
Now,
V = A × h
= 100 × 6 = 600 cm2

"Since the fall of 2008, millions of Americans have lost jobs due to the economic meltdown. A recent study shows that unemployment has not impacted males and females in the same way (Newsweek,April 20, 2009). The unemployment rate is 8.8% for eligible men and only 7.0% for eligible women. Suppose 52% of the eligible workforce in the U.S. consists of men. What is the probability that a randomly selected worker is both female and employed?"
Answer: 0.42%.
Step-by-step explanation:
Probability of (M(Eligible Men)) = 0.52
Probability of (W(Eligible Women)) = 1 - 0.52
= 0.48
Probability of (UM(Unemployed Men)) = 0.088
Probability of (UW(Unemployed Women)) = 0.070.
therefore;
Probability that the worker is a man = [P(UM)*P(M)]/[P(UM)*P(M) + P(UW)*P(W)] = 0.576613
0.088 * 0.52 )/ 0.088 * 0.52 + 0.070 * 0.48
= 0.04576 / 0.07936
= 0.5766
probability that the randomly selected worker is both female and unemployed is
= 1 – 0.58%
= 0.42%

Six times the sum of a number and seven is 30. Find the number.
Answer:
x = -2
Step-by-step explanation:
6(x+7)=30
6x+42=30
6x=-12
x=-2
Step-by-step explanation:
Hey there!!
According to the question,
One number is 7.
Let another no. be x.
So, the condition is 6(x+7)= 30
Now,
6(x+7) = 30
6x +42 = 30
6x = 30-42
[tex]x = \frac{ - 12}{6} [/tex]
Therefore the no. is -2.
Check,
6(-2+7)= -12 + 42 = 30 { they gets subtracted but sign remains (+) only }.
Hope it helps....
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.
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

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.

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.
