how many solutions does it have

The two base numbers can be represented as x and y. Setting them equal in the equation x * y = 2(x + y) allows you to solve for them. One solution is x = 2 and y = 2.

This problem can be solved using basic algebra. Let's assume the two base numbers be x and y. Since the product of the two base numbers (x * y) is twice as large as the sum of those numbers (x + y), we can create the following equation: x * y = 2(x + y).

To solve for x and y, you may set x and y to different numbers and check if they satisfy the equation. One solution is x = 2 and y = 2, since 2*2 = 2(2+2). Similarly, other pairs of numbers may also satisfy this equation based on the specific constraints of Frederick's number puzzle.

To solve the number puzzle, we need to find two base numbers whose product is exactly twice as large as their sum. By rearranging the terms and factoring, we can find the base numbers that satisfy the equation. An example solution is provided with a = 3 and b = 6.

To solve the number puzzle, we need to find two base numbers whose product is exactly twice as large as their sum. Let's represent the base numbers as 'a' and 'b'. According to the information given, we have the equation:

ab = 2(a + b).

We can simplify the equation by rearranging the terms and factoring: ab - 2a - 2b = 0. Using a technique called 'completing the square', we can rewrite the equation as (a - 2)(b - 2) = 4.

From here, we can choose different values for 'a' and 'b' that satisfy the equation, such as a = 3 and b = 6. Therefore, the base numbers for the number puzzle are 3 and 6.

For the round trip of 930 miles each way, you will need to purchase about 62 gallons of gas, given a car's gas mileage of 30 miles per gallon.

To calculate the gallons of gas needed for the round trip, follow these steps:

Calculate the total distance for the round trip.

The round trip distance is twice the one-way distance.

Round trip distance = 2 * 930 miles = 1860 miles.

Find the number of gallons required for the round trip.

Divide the total distance by the car's gas mileage (miles per gallon).

Gallons required = Round trip distance / Gas mileage

Gallons required = 1860 miles / 30 miles per gallon

Perform the division.

Gallons required = 62 gallons.

Round the answer.

Since you cannot purchase a fraction of a gallon, round the answer to the nearest gallon.

You will need to purchase approximately 62 gallons of gas for the round trip.

So, to make the trip to see your friends and return home, you will need to purchase about 62 gallons of gas.

Answer:

I am pretty sure this is either a Linear Equation or called a Contradiction

An equation that is not true for any values of the variable is called a false or inconsistent equation.

An equation that is not true for any values of the variable is called a false equation or an inconsistent equation. This means that the equation has no solution that satisfies the given equation. For example, if we have the equation x + 3 = x + 5, subtracting x from both sides gives us 3 = 5, which is not true for any value of x.

Final answer:

The scale factors for the points given are 1.5 for A to A', indicating an enlargement, and 0.5 for B to B', indicating a reduction. G to G' also indicates a reduction with a factor of 0.5.

Explanation:

To determine the scale factor given the point and its image, you can find the ratio between the coordinates of the image and the original coordinates. Let's analyze the pairs of points you've provided:

A (3, 6) and A' (4.5, 9)

G (1.5, 3) and G' (3, 6)

B (2, 5) and B' (1, 2.5)

We can find the scale factor by dividing the x-coordinates of the image by the original x-coordinate and doing the same for the y-coordinates. For point A:

Scale factor for x: 4.5 / 3 = 1.5

Scale factor for y: 9 / 6 = 1.5

For point G, we see that it's actually the reverse (original to image), but you can still calculate:

Scale factor for x: 3 / 1.5 = 2

Scale factor for y: 6 / 3 = 2

Lastly, for point B:

Scale factor for x: 1 / 2 = 0.5

Scale factor for y: 2.5 / 5 = 0.5

So, the scale factors for A to A' and for B to B' are 1.5 and 0.5, respectively, showing that A to A' is an enlargement while B to B' is a reduction. For G to G', the reverse is a reduction with a factor of 0.5.

To convert the distance from the Earth to the Moon from miles to feet, multiply 250,000 miles by the number of feet in a mile, which is 5,280. This calculation yields a result of approximately 1.32 billion feet.

The distance from the Earth to the Moon is given as 250,000 miles. To convert this distance from miles to feet, we use the fact that there are 5,280 feet in a mile. Thus, we multiply the distance in miles by the number of feet per mile.

To find the distance in feet, perform the following calculation:

Multiply the distance in miles by the number of feet per mile: 250,000 miles × 5,280 feet/mile.

This equals 1,320,000,000 feet.

Therefore, the Moon is approximately 1.32 billion feet away from Earth.

The solution to the inequality -1.3 ≥ 2.9 -0.6r, is r ≤ 7. This is represented on a graph by placing a closed circle on 7 and drawing a line to the left, to represent all numbers less than 7.

To solve this inequality, -1.3 ≥ 2.9 -0.6r, first, we isolate the variable r (which represents solving for 'r'). Start by subtracting 2.9 from both sides of the inequality.

This gives us -4.2 ≥ -0.6r. Then divide both sides by -0.6. However, remember when dividing or multiplying an inequality by a negative number, the direction of the inequality changes. So, it becomes r ≤ 7.

When graphing this inequality, you will place a closed circle at 7 (showing that point is included) and draw a line to the left from 7, extending to infinity (since all numbers less than 7 satisfy the inequality).

The graph represents the mathematical solution to the inequality.

Answer: One card is 0.005 inches thick.

Step-by-step explanation:

Since we have given that

Number of cards in a stack = 150

Thickness of the stack = [tex]\dfrac{3}{4}\ inches[/tex]

So, Thickness of each card is calculated by "Unitary method":

Thickness of 150 cards  = [tex]\dfrac{3}{4}\ inches[/tex]

Thickness of 1 card is given by

[tex]\dfrac{3}{4\times 150}\\\\=\dfrac{1}{4\times 50}\\\\=\dfrac{1}{200}\\\\=0.005\ inches[/tex]

Hence, One card is 0.005 inches thick.

Answer:  The correct option is (C) [tex]\dfrac{1}{4}.[/tex]

Step-by-step explanation:  We are given to find the common ratio for the following geometric sequence :

64,   16,   4,   1,   .   .    .

We know that

if a(n) represents the n-th term of a geometric series, then the common ratio is given by

[tex]r=\dfrac{a(n+1)}{a(n)},~~~n=0,~1,~2,~~.~~.~~.[/tex]

For the given geometric sequence, we have

a(1) = 64,  a(2) = 16,  a(3) = 4,  a(4) = 1,  .  .  .

So, the common ratio r will be given by

[tex]r=\dfrac{a(2)}{a(1)}=\dfrac{a(3)}{a(2)}=\dfrac{a(4)}{a(3)}=~~.~~.~~.[/tex]

We have

[tex]\dfrac{a(2)}{a(1)}=\dfrac{16}{64}=\dfrac{1}{4},\\\\\\\dfrac{a(3)}{a(2)}=\dfrac{4}{16}=\dfrac{1}{4},\\\\\\\dfrac{a(4)}{a(3)}=\dfrac{1}{4},~~\cdots[/tex]

Thus, the required common ratio for the given geometric sequence is [tex]\dfrac{1}{4}.[/tex]

Option (C) is CORRECT.
