Answer:

the answer is actually 3x - 0.03 = 0.75

Step-by-step explanation:

To solve for x in the equation 6(x – 1) = 9(x + 2), expand and simplify the equation, combine like terms, isolate the variable x, and solve for x by dividing both sides by 3.

To solve for x in the equation 6(x – 1) = 9(x + 2), we can begin by expanding the equation:

6x - 6 = 9x + 18

Next, we can combine like terms by subtracting 6x from both sides:

-6 = 3x + 18

Then, we can isolate the variable x by subtracting 18 from both sides:

-24 = 3x

Daniel can go on 14 rides at the fair.

To find out the greatest number of rides Daniel can go on, we need to calculate the cost of admission and the cost of the rides. The admission to the fair is $4 and each ride costs $1.50. To determine the number of rides, we subtract the cost of the admission from the total amount Daniel has to spend and then divide that by the cost of each ride. So, Daniel can go on (25 - 4) / 1.50 = 14 rides. Therefore, the greatest number of rides Daniel can go on is 14.

Answer:

[tex]\frac{16}{25} =0.64[/tex]

Step-by-step explanation:

Given : A spinner used for a game is divided into 4 sections: Yellow, Brown, Red and Orange. The spinner is spun 50 times and lands on brown 18 times

To Find: What is the experimental probability that the spinner does NOT land on brown

Solution :

Since we are given that the spinner is spun 50 times .

Ans the spinner lands on brown 18 times

Probability of landing on brown = [tex]\frac{18}{50} =\frac{9}{25}[/tex]

Since we know that the sum of probabilities is 1

So, probability that the spinner does NOT land on brown is :

⇒ 1 - prob. of landing on brown

⇒[tex]1-\frac{9}{25}[/tex]

⇒[tex]\frac{25-9}{25}[/tex]

⇒[tex]\frac{16}{25}[/tex]

Thus probability that the spinner does NOT land on brown is 16/25=0.64

The estimated sum of 521,370 and 26,839, when rounded to the nearest hundred, is 548,200.

To find the estimated sum, you first need to round each number to the nearest hundred before adding them. For the given numbers 521,370 and 26,839, we round them as follows:

521,370 rounds to 521,400 (because the number after the hundreds place, 7, is 5 or greater, so we round up).

26,839 rounds to 26,800 (because the number after the hundreds place, 3, is less than 5, so we round down).

Now we add the rounded numbers:

521,400 + 26,800 = 548,200

So, the estimated sum of 521,370 and 26,839 is 548,200.

Answer:

A. 50 − 2.5x = y

 40 − 2x = y

Step-by-step explanation:

We know that x represents the number of trips and y represents the amount remaining in each account, then, let's think in an example; after the first trip x = 1, therefore, Kaisorn's account must decrease from $50 to $50 - $2.5 = $47.5 = y, and Thom's account must decrease from $40 to $40 - $2 = $38 = y. Replacing x = 1 in each case gives:

A

50 − 2.5(1) = y

47.5 = y

   40 − 2(1) = y

   38 = y

B

50 + 2.5(1) = y

52.5 = y

 40 + 2(1) = y

 42 = y

C

50 − 2.5y = (1)

y = (1 - 50)/(-2.5)

y = 19.6

 40 − 2y = (1)

  y = (1 - 40)/(-2)

  y = 19.5

D

50 + 2.5y = (1)

y = (1 -50)/2.5

y = -19.6

 40 + 2y = (1)

 y = (1 - 40)/(2)

 y = -19.5

As it can be seen, option A is the correct one.

Step-by-step explanation:

Answer:

Surface Area of Design = 256 in.²

Step-by-step explanation:

Given: a Shape which is made by placing two cuboid on one another.

To find: Surface area of shape.

Figure is attached.

Surface Area of Design

= Lateral Surface Area of Base Cuboid + Lateral Surface area of Top Cuboid + Area of rectangle CDLJ + Area of rectangle EFNM + Area of rectangle ABHG

Dimensions of Base Cuboid:

Length, CJ = 8 in.

Width, CD = LJ = MN = 5 in.

Height, AD = 4 in.

Dimensions of Top cuboid:

Length, HI = BI - BH = 8 - 4 = 4in.

Width, GH = KI = MN = 5 in.

Height, FH = JN - JI = 8 - 4 = 4 in.

Length of rectangle ABHG, AB = 5 in.

Width of rectangle ABHG , BH = 4 in.

Length of rectangle DCJL, DC = 5 in.

Width of rectangle DCJL , CJ = 8 in.

Length of rectangle EFNM, EF = 5 in.

Width of rectangle EFNM , FN = 4 in.

Lateral Surface Area of Base Cuboid = 2 × Height ( length + Width )

                                                              = 2 × 4 ( 8 + 5 )

                                                              = 8 ( 13 )

                                                              = 104 in²

Lateral Surface Area of Top Cuboid = 2 × Height ( length + Width )

                                                              = 2 × 4 ( 5 + 4 )

                                                              = 8 ( 9 )

                                                              = 72 in²

Area of rectangle DCJL = length × breadth

                                        = 5 × 8

                                        = 40 in.²

Area of rectangle ABHG = length × breadth

                                        = 5 × 4

                                        = 20 in.²

Area of rectangle EFNM = length × breadth

                                        = 5 × 4

                                        = 20 in.²

⇒ Surface Area of Design = 104 in.² + 72 in.² + 40 in.² + 20 in.² + 20 in.²

                              = 256 in.²

Therefore, Surface Area of Design = 256 in.²

To find the 7th term in the geometric sequence, determine the common ratio using given terms, a2 and a4, then use the formula for the nth term to calculate a7. The common ratio is 1/4, and the 7th term is 0.75.

The student is asking to find the 7th term (a7) of a geometric sequence for which the 2nd term (a2) is 768 and the 4th term (a4) is 48. To solve for the 7th term, we must first determine the common ratio of the sequence.

We know that in a geometric sequence, each term is the product of the previous term and the common ratio (r). The formula for the nth term of a geometric sequence is an = a1 * r^(n-1), where a1 is the first term and n is the term number.

Since a4 is the 4th term and a2 is the 2nd term, we can write these equations:
a4 = a2 * r^(4-2)48 = 768 * r^2
By solving this equation, we get:
r^2 = 48 / 768 = 1 / 16, which means r = 1 / 4.

Now that we know the common ratio, we can find the 7th term (a7) by using the formula from above with n = 7:
a7 = a2 * r^(7-2) = 768 * (1/4)^(7-2) = 768 * (1/4)^5 = 768 * 1/1024 = 0.75

Hence, the 7th term of the given geometric sequence is 0.75.

To evaluate 10⁻⁷, it is understood as 1 divided by 10 to the seventh power, or 0.0000001. This notation is used in scientific measurements, for instance in expressing the hydronium ion concentration based on pH.

Explanation:

To evaluate 10⁻⁷, we must understand the notation of negative exponents.

10 raised to the power of -7 can be written as 1 divided by 10 raised to the power of 7:

10⁻⁷ = 1 / 10⁷

Since 10 raised to any positive power results in a large number, 10 raised to the power of 7 is a very large number (10,000,000). Dividing 1 by this large number is very close to zero:

1 / 10⁷≈ 0.000 000 1

Therefore, 10⁻⁷ is approximately equal to 0.000 000 1. This value is incredibly small, representing one divided by ten million.

This type of notation is commonly used in scientific measurements, such as expressing the concentration of hydrogen ions in a solution with a certain pH level.

Next, the word of means "multiply" so we have to multiply 0.65 by 40.

(.65) × (40) = 26.00

To calculate 65 percent of 40, convert 65% to a decimal (0.65) and then multiply by 40 to get the answer, which is 26.

To find what 65 percent of 40 is, you can convert the percentage to a decimal and then multiply by the number. To convert a percentage to a decimal, divide it by 100. In this case, 65% becomes 0.65.

Next, multiply 0.65 by 40 to get the answer.

The calculation process looks like this:
0.65 (converted percentage) × 40 (the number) = 26

Therefore, 65 percent of 40 is 26.

Since f(x) is an even function, the statement which is true is the graph of f(x) has a line of symmetry about the y-axis.

To answer the question, we need to know what an even function is.

An even function is a function f(x) such that f(x) = f(-x). That is f(x) is single valued for both positive and negative values of x.

Now, for an even function, since f(x) = f(-x), both positive and negative values of x give a single value of f(x).

For this to be true, the graph of f(x) is symmetric about the y-axis.

So, since f(x) is an even function, the statement which must be true is graph of f(x) has a line of symmetry about the y-axis.
