Answer:

64

Step-by-step explanation:

The exponent of a number says how many times to use the number in a multiplication.

8 to the Power 2

In 82 the "2" says to use 8 twice in a multiplication,

so 82 = 8 × 8 = 64

In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"

After answering the presented question, we can conclude that As a result, the system of equations solution is (3, 35).

An equation is a mathematical statement that validates the equivalent of two expressions joined by the equal symbol '='. For instance, 2x - 5 = 13. 2x-5 and 13 are two examples of expressions. The character '=' connects the two expressions. An equation is a mathematical formula that has two algebras on each side of an assignment operator (=). It demonstrates the equivalency link between the left and middle formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

Thus the first month's savings would be: (Regular price) - (Discounted price) = (151 + 20) - (101 + 5) = $20.

Part C: Using the equations from Parts A and B, we can construct the following system of equations:

Y = 10X + 5 (Discounted pricing equation) (Discounted price equation)

Y = 15X + 20 (Normal price equation) (Regular price equation)

We can solve this system by substituting one equation for the other:

10X + 5 = 15X + 20

When we simplify this equation, we get:

5X = 15

X = 3

Then we can plug X = 3 into either equation to determine the value of Y:

Y = 10(3) + 5 = 35

As a result, the system of equations solution is (3, 35).

The probability that the spinner lands on red and the coin toss is tails is 0.4

The sections on the spinner are

Yellow = 4

Red = 16

This means that

P(Red)=Red/Total

So, we have the following representation

P(red) = 16/20

Also, we have

Coin = {H, T}

This means that

P(T) = 1/2

So, we have

P(Red and Tail) = P(Red) * P(T)

So, we have

P(Red and Tail) = 16/20 * 1/2

Evaluate

P(Red and Tail) = 0.4

So, the probability is 0.4

Answer:

6,560

Step-by-step explanation:

Answer:

6,560

Step-by-step explanation:

We are given the first four terms of the sequence:

2, 6, 18, 54, ...

We need to find another four terms to find the sum.

I don't know how to explain how I got the pattern but you have to multiply by 3:

2 * 3 = 6

6 * 3 = 18

18 * 3 = 54

To find the next term, we will multiply 54 by 3:

54 * 3 = 162

2, 6, 18, 54, 162, ...

We now have 5 terms.

Next, multiply 162 by 3:

162 * 3 = 486

2, 6, 18, 54, 162, 486, ...

We now have 6 terms.

Next, multiply 486 by 3:

486 * 3 = 1458

2, 6, 18, 54, 162, 486, 1458, ...

We now have 7 terms.

Lastly, multiply 1458 by 3:

1458 * 3 = 4374

2, 6, 18, 54, 162, 486, 1458, 4374, ...

We now have the first 8 terms.

Now, we add all these numbers together:

2 + 6 + 18 + 54 + 162 + 486 + 1458 + 4374 = 6560

The sum of the first eight terms of the geometric sequence is 6,560

the dimensions of the rectangle with the largest area is Length = Diameter of the semicircle = 4 inches and Width = Radius of the semicircle = 2 inches.

consider a semicircle with radius 2 inches.

The diameter of the semicircle is twice the radius, which is 4 inches. This diameter will be the length of the rectangle.

Since the rectangle is inscribed in the semicircle,

the width of the rectangle= the radius of the semicircle = 2 inches.

Therefore, the dimensions of the rectangle with the largest area that can be inscribed in the semicircle are:

Length = Diameter of the semicircle = 4 inches

The value of the friction force on the sofa will be 288 N.

The force which opposes the motion of the body is known as friction force.

Ralph wants to move a 60.0 kg sofa.

He applies a force of 480 N.

Under these conditions, the sofa initially moves with an acceleration of 3.20 m/s².

Then the value of the friction force on the sofa will be

We know

ΣF = ma

We have

m = 60 kg

a = 3.2 m/s²

Then the value of friction force will be

480 – f = 60 × 3.2

480 – f = 192

          f = 480 – 192

          f = 288 N

These steps are often referred to as the principle of mathematical induction or PMI.

The steps for mathematical induction are:

Base Case: Show that the statement holds for some particular value of n, usually n = 1 or n = 0.

Inductive Hypothesis: Assume that the statement holds for some arbitrary value of n = k, where k is a positive integer.

Inductive Step: Using the inductive hypothesis, show that the statement also holds for n = k + 1.

Conclusion: By the principle of mathematical induction, the statement is true for all positive integers n.

These steps are often referred to as the principle of mathematical induction or PMI. They are used to prove statements that involve an infinite set of integers by showing that the statement holds for a base case, assuming that it holds for an arbitrary value, and then showing that it holds for the next integer in the set.

Fluffy the bunny ate 1/12 of the carrot at night.

Define ratio

Ratio is a mathematical comparison between two quantities that are related to each other in some way. It is expressed as the quotient of one quantity divided by the other.

Fluffy ate 1/4 of the carrot in the morning.

By the end of the day, Fluffy had 2/3 of the carrot left to eat. This means she had eaten 1 - 2/3 = 1/3 of the carrot by the end of the day.

Since Fluffy ate 1/4 of the carrot in the morning, subtracting that from the 1/3 of the carrot that she had eaten by the end of the day to find out how much she ate at night:

Amount of carrot Fluffy ate at night = 1/3 - 1/4

To subtract these fractions, we need a common denominator:

Amount of carrot Fluffy ate at night = (4/12) - (3/12)

Amount of carrot Fluffy ate at night = 1/12

Therefore, Fluffy the bunny ate 1/12 of the carrot at night.

Connect the points where the first arc crosses the triangle's base and the second arc intersects the base of the triangle with the straightedge to create the triangle's third side, BC.

Generally, To accurately construct triangle ABC, you will need a straightedge (such as a ruler) and a protractor. Here are the steps to follow:

Use the straightedge to draw a straight line segment of length 8 cm, which will represent side AB. This line segment will be the base of the triangle.

Place the point of the protractor at one end of the line segment and draw an arc that intersects the other end of the line segment.

Measure the angle formed by the line segment and the arc using the protractor. The measure of this angle should be 70 degrees.

Without changing the position of the protractor, draw another arc that intersects the first arc and the base of the triangle.

Use the straightedge to connect the point where the second arc intersects the base of the triangle to the point where the first arc intersects the base of the triangle. This will form the third side of the triangle, AC.

Finally, use the straightedge to draw the third side of the triangle, BC, by connecting the point where the first arc intersects the base of the triangle to the point where the second arc intersects the base of the triangle.
