Answer: All values/solutions of P must be greater than 2 to be true to the inequality 10p-8>12

Step-by-step explanation:

When solving inequalities, we treat it like an equation, solving for the variable, in this case, p.

10p - 8 > 12

Lets isolate p

10p - 8 > 12

       +8   +8

10p > 20

/10     /10

p > 2

After solving, we now know that all values of P must be greater than 2.

A. The circular base of the bucket is larger.

B. The bale has a larger volume.

A. The circular base of the bucket has a larger area than the rectangular base of the bale.

The formula for the area of a circle is π * r^2, where r is the radius. The diameter of the bucket is 3 feet, so the radius is 3/2 feet. The area of the circular base is therefore π * (3/2)^2 = 7.07 square feet.

The rectangular base of the bale has length 2 feet and width 3 feet, so its area is 2 * 3 = 6 square feet.

Since 7.07 > 6, the circular base of the bucket is larger.

B. The bale has a larger volume than the bucket.

The formula for the volume of a rectangular prism is l * w * h, where l is the length, w is the width, and h is the height. The bale has length 2 feet, width 3 feet, and height 5 feet, so its volume is 2 * 3 * 5 = 30 cubic feet.

The formula for the volume of a cylinder is π * r^2 * h, where r is the radius and h is the height. The radius of the bucket is 3/2 feet and the height is 5 feet, so the volume of the bucket is π * (3/2)^2 * 5 = 22.36 cubic feet.

Since 30 > 22.36, the bale has a larger volume.

The best first step to begin to simplify the equation -2(x + 3) = -10​ is:

Dividing both sides of the equation by -2 to get x + 3 = 5

As per the given data, the equation is given by -2(x + 3) = -10

We have to determine the best first step in solving the equation:

-2(x + 3) = -10​

Firstly we start by distributing -2 in the bracket (x + 3)

-2x - 6 = -10

Or

-2(x + 3) = -10​

Also if we divide both sides of the equation by -2, we get

x + 3 = 5

Now, we can easily solve the equation.

Hence, the first best step to begin to simplify the equation -2(x + 3) = -10​ is:

Distributing -2 in the bracket (x+3)

We get -2x -6 = -10

Or Dividing both sides of the equation by -2

The equation for the discounted price should be:

A' = $25*(1 - 20%/100%) = $20

If we have an initial value A, and we decrease it by X (a percentage) then:

The discounted amount is:

D = A*(X/100%)

The new value is:

A' = A*(1 - X/100%)

So, if the initial value is $25 and there is a discount of the 20%, the new value of the item will be:

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

Given that,

Edward is flying a kite on a beautiful sunny day at the beach,

An angle of elevation of 40°

kite string let out = 100 meter

The height of his kite = ?

Suppose, height  = h

if we consider horizontal distance of kite from the Edward and Vertical distance from the Edward

It will form a right angle triangle

Now, we can use sine formula in the right angle triangle,

α =  40°

L  = 100 meter

h  = ?

It is known that,

sinα  = height/hypotenuse

G. y ≤ 3x − 1

In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:

Where:

Next, we would determine the linear equation representing the line of f(x) which passes through the points (0, 4) and (4, 0) by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 0 = (4 - 0)/(0 - 4)(x - 4)

y - 0 = -1(x - 4)

y = -x + 4

Answer:

0.00000016

Step-by-step explanation:

Raise 0.02 to the power of 4.

0.000000256.

The expression (0.02)^4 represents the fourth power of 0.02. In mathematical terms, "^" symbol is used to indicate exponentiation, so (0.02)^4 is equal to 0.02 multiplied by itself 4 times.

To calculate this expression, we can multiply 0.02 by itself 4 times:

0.02 * 0.02 * 0.02 * 0.02 = (0.02)^4 = 0.000000256

So, the result of (0.02)^4 is approximately equal to 0.000000256.

The event that "a or b but not both" P{(A∩B) ∪ (A ∩B)}

= P(A∩B) + P(A∩B) - P(A∩B∩A ∩B)

In this question, we will use the addition rule of the probability to calculate the required probability. The probability is a positive quantity from zero to one inclusively. The negative probability of an event does not exist

This is for independent events

P(A U B): This is A or B or both:

P(A n B): This is A and B.

P(A U B) = P(A) + P(B) - P(A n B)

P( A n B) = P(A) x P(B)

Hence:

A or B but not both:

P(A U B) = P(A) + P(B) - P(A n B) - P(A n B) = P(A) + P(B) - 2 x P(A n B)

can also be written in terms of the conditional probability P(A|B)

So we can write

P{(A∩B) ∪ (A ∩B)}

= P(A∩B) + P(A∩B) - P(A∩B∩A ∩B)
