a. Is x = 0 a solution to both inequalities?
b. Is x = 4 a solution to both inequalities?
c. Find another value of x that is a solution to both inequalities.
Answers
a) The value of x=0 will be a solution for both the inequalities .
b) One equality is false and only one in correct when value of x = 4
What is inequalities?
In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.a) x =0
i) -2.x < 10
-2(0) < 10
0 < 10
ii) -6 < -2x
-6 < -2(0)
-6 < 0
The value of x will be a solution for both the inequalities .
b) x = 4
i) -2.x < 10
-2(4) < 10
-8< 10
ii) -6 < -2x
-6 < -2(4)
-6 < -8
Hence, one inequality is false and only one in correct when the value of x =4.

Answers
Two numbers are in the ratio 4: 7. If their L.C.M. is 168,The numbers would be 56 and 98.
The smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm) in mathematics and number theory. It can also be referred to as the lowest common multiple (lcm), or the smallest common multiple of two numbers (a and b).
The given ratio is 4:7, which can be written as 4/7.
To find the individual numbers, we can use the formula:
Number1 = LCM × Ratio1/ (Ratio1 + Ratio2)
Number2 = LCM × Ratio2/ (Ratio1 + Ratio2)

Find the volume of a right circular cone that has a height of 6.5 cm and a base with a radius of 8.5 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answers
The volume of the right circular cone is 122.94754 in³.
What is the right circular cone?
The axis of a right circular cone is the line joining the vertex and the base's center.
In other words, a right angle is formed at the place where the apex of the cone and the center of the circular base meet.
Following is the correct circular cone volume formula:
V=1/3hπr²
Diameter = 8.5 in
Radius = 8.5/2 = 4.25 in
Now calculate the volume as follows:
V = 1/3hπr²
V = 1/3(6.5)π(4.25)²
V = 122.94754 in³
Therefore, the volume of the right circular cone is 122.94754 in³.

a trough is 10ft long and its ends have the shape of isoscles triangles that are 3ft across at the top and have a height of 1ft. if the trough is being filled with water at a rate of 12ft/min, how fast is the water level rising when the water is 6 inches deep?
Answers
The rate at which the water level is rising when the water is 6 inches deep is 4/5 ft/min .
In the question ,
it is given that ,
the length of the trough is = 10 ft ,
the width is (w) = 3 ft ,
the height of the trough is (h) = 1 ft ,
we get the relation between width and height is w = 3h ;
The formula for Volume is written as = Area of triangle * length
= 1/2 × h × w × l
= (1/2) × 3h × h × 10
So , V = 15h² .
Differentiating the given with respect to time "t" ,
we get ,
dV/dt = 30×h×dh/dt
given that , the trough is being filled with water at a rate of 12ft/min,
that means ,
dV/dt = 12
So , the rate of change of water level when the water is 6 inches deep can be calculated using the formula .
we know that 6 inches = 6/12 ft
12 = 30×(6/12)×dh/dt
dh/dt = 12/15 = 4/5 ft/min
Therefore , the water level is rising at the rate of 4/5 ft/min .

According to question:
Allow the two numbers to be an and b, with a<b. Look at an acknowledgment of X (free of your decision of an or b) with the worth of the main number you see. Assuming that X is greater, switch, in any case keep the number.
The likelihood of winning can be registered as follows:
In the event that you pick a (with 12 possibility), you win assuming you switch, ie if X>a. This has prob. P(X>a).
Comparably assuming you pick b (with 12 possibility), you win on the off chance that you don't switch, ie if X≤b. This has prob. P(X≤b).
So the general likelihood of winning is 1/2+1/2P(a<X≤b), which is marginally bigger than 1/2 in view of our presumptions on X.

How do you solve an equation with x and y in one?
Answers
There are infinitely many solutions to an equation with two variables.
We know that an equation is a mathematical statement that contains equal symbol between two mathematical expressions.
In this question need to solve an equation with x and y in one equation.
Consider an equation with two variables: 5x + y = 8
If we solve given equation for x then it would be,
5x + y = 8
5x + y - y = 8 - y
5x/5 = (8 - y)/5
x = (8 - y)/5
for any arbitrary real value value of y we can find the value of x.
This means there are infinitely many solutions.
If we solve given equation for y then it would be,
5x + y = 8
5x + y - 5x = 8 - 5x
y = 8 - 5x
for any arbitrary real value value of x we can find the value of y.
Therefore, an equation with two variables has infinitely many solutions.
