Answer:

Since 2 and 3 are factors, they should be multiplied to get 6xy.

Step-by-step explanation:

The solution is Option B.

Since 2 and 3 are factors, they should be multiplied to get 6xy and the equation is False

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

2x + 3y ≠ 5xy

a)

If you substitute 4 for x and 5 for y in the expression 2x+3y, it does not equal 5(4)(5)

Substituting the value of x = 4 and y = 5 in the equation , we get

2 ( 4 ) + 3 ( 5 ) ≠ 5 ( 4 ) ( 5 )

8 + 15 ≠ 100

23 ≠ 100

Therefore , the statement is True

b)

Since 2 and 3 are factors, they should be multiplied to get 6xy

2x ( 3y ) = 6xy

But the equation does not equals 6xy

Hence , the statement is False and does not explain the given equation

c)

x and y are not like terms

The statement is true because the variables x and y are not the same

Therefore , the statement is True

d)

Adding x and y is not the same as multiplying x and y

The value of the equation x + y = x + y and on multiplying x and y = xy

And , x + y ≠ xy

Therefore , the statement is True

Hence , the equation 2x ( 3y ) = 6xy is False

Answer:

960 ft^2

Step-by-step explanation:

There are 9 surfaces forming the solid.

5 of them are congruent squares and 4 of them are congruent triangles.

area of square = (side)^2

area of triangle = (base)(height)/2

total surface area = 5 * area of square + 4 * area of triangle

A = 5 * (12 ft)^2 + 4 * (12 ft * 10 ft)/2

A = 5 * 144 ft^2 + 4 * 60 ft^2

A = 720 ft^2 + 240 ft^2

A = 960 ft^2

This solid is a composite of a cube and square pyramid. the total surface area of the solid is 960 ft^2.

The area of a square can be calculated as the square of the sides of a given figure.

The area of square = (side)^2

We know that

The area of triangle = (base)(height)/2

So,

The total surface area = 5 x area of square + 4 x area of a triangle

A = 5 x (12 ft)^2 + 4 x (12 ft x 10 ft)/2

A = 5 x 144 ft^2 + 4 x 60 ft^2

A = 720 ft^2 + 240 ft^2

A = 960 ft^2

Thus, The total surface area of the solid is 960 ft^2.

The probability of getting all tails when flipping a coin three times can be calculated using the multiplication rule of probability. For each flip of the coin, there are two possible outcomes: heads or tails.

Assuming the coin is fair, both outcomes are equally likely, so the probability of getting tails on any one flip is 1/2.

P(all tails) = P(tails on first flip) x P(tails on second flip) x P(tails on third flip)

= (1/2) x (1/2) x (1/2)

= 1/8

Therefore, the probability of getting all tails when flipping a coin three times is 1/8 or 0.125 when expressed as a decimal rounded to four decimal places.

With a 20% discount on sneakers that originally cost $25.00, the sale price can be calculated by subtracting 20% of $25.00 from the original price. The sale price of the sneakers is $20.00.

To calculate the sale price of the sneakers, we need to apply the 20% discount to the original price of $25.00. To find the discount amount, we calculate 20% of $25.00, which is (20/100) * $25.00 = $5.00. This means the discount on the sneakers is $5.00.

To determine the sale price, we subtract the discount amount from the original price. In this case, $25.00 - $5.00 = $20.00. Therefore, the sale price of the sneakers is $20.00.

The discount of 20% reduces the price by one-fifth of the original price, which is a significant reduction. It is important to note that the discount percentage may vary depending on the specific promotion or offer available at the Sneaker Shack.

Answer:

Rafael will read 240 pages.

Step-by-step explanation:

Let's start by setting up the unknowns:

x = # of Rafael's pages

x/2 = # of Philippe's pages

(3/4)x = # of Denise's pages

Set these all equal to 540:

(x) + (x / 2) + (3/4(x)) = 540

Let's multiply both sides by 4 to make this easier.

4x + 2x + 3x = 2160

9x = 2160

x = 240

x was the # of Rafael's pages, so Rafael will read 240 pages. This means that Philippe will read 120 pages (one-half of Rafael), and Denise will read 180 pages (three-fourths of Rafael). Adding these all up will get you 540 pages, so it checks out.

Firstly, simplify. Divide by 2 to get

2(x^2-3x+2) = 0

Move the constant to the other side.

2(x^2-3x) = -2

Divide the x term by 2 and square it

-3/2^2 = 9/4

Add this result to both sides.

2(x^2-3x+9/4) = 1/4.
Put the perfect sq on both sides
2(x-3/2)^2=1/4
Then solve the equation:

take the sqrt of both sides and isolate x for each solution

x-3/2= +/-1/2
x = 3/2 + 1/2
x= 3/2-1/2

The exponential form of the given complex number is 5e^(i135°).

Expressing 5(cos135° + jsin135°) in exponential form:

To convert the given complex number to exponential form, we use Euler's formula, which states that e^(ix) = cos(x) + isin(x). Here, we have 5(cos135° + jsin135°), so let's apply Euler's formula:

5(cos135° + jsin135°) = 5e^(i135°)

The exponential form of the given complex number is 5e^(i135°).

To convert from the trigonometric form (cosθ + jsinθ) to exponential form, we utilize Euler's formula. In Euler's formula, e^(ix) represents the exponential form of cos(x) + isin(x), where e is the base of the natural logarithm and i is the imaginary unit.

In this case, the angle is 135°, so we substitute θ = 135° into Euler's formula:

e^(i135°) = cos(135°) + isin(135°)

Using the trigonometric identities, we can calculate cos(135°) and sin(135°):

cos(135°) = -√2/2

sin(135°) = √2/2

Thus, the exponential form becomes:

5e^(i135°) = 5(-√2/2 + i√2/2)

The complex number 5(cos135° + jsin135°) can be expressed in exponential form as 5e^(i135°), where e is the base of the natural logarithm. The calculation involved substituting the angle into Euler's formula and simplifying the trigonometric functions to determine the real and imaginary components.

(a) 3(cos232° + jsin232°)

Answer:

the jet could fly 2565 miles in 9 hours

the rate is hours:miles     1:285

Step-by-step explanation:

you do 570/2=285

then you multiply the answer by 9

Answer:

Step-by-step explanation:

Given: A jet travels 570 miles in 2 hours. 11 hours = ___

To find: At this rate, how far could the jet fly in 11 hours? What is the rate the speed of the jet?

Formula: Distance = rate × time. Speed = distance ÷ time.

Solution:

Part 1: The rate/speed of the jet:-

Use the formula to solve:

r (rate) × 2 (hours) = 570 (distance)

r =\(\frac{570}{2}\)

r = 285 miles per hour

The rate of speed of the jet is 285 mph.

Part 2: How far the jet could fly in 11 hours:-

Then, to find out the distance flown in 11 hours;

285 (rate) × 11 (time) = d (distance)

285 × 11 = d

3135 = d

The distance flown in 11 hours is 3135 miles.

Step-by-step explanation:

Speed is independent and distance is dependent

Distance depends on the speed

Speed influences the distance

The engineer's improved light bulb likely has a statistically significant longer lifetime than the previous design, with a small but measurable difference of 0.2 hours.

Statistical significance refers to the probability that the observed difference between two groups (in this case, the old light bulbs and the new ones) is not due to chance alone. If the probability is low enough, we can confidently reject the null hypothesis (that there is no difference between the two groups) and conclude that there is a real difference between them.

In this case, a sample size of 40,000 bulbs is quite large, which increases the statistical power of the test and allows for even small differences to be detected as significant. The fact that the new bulb had a slightly longer lifetime of 1,200.2 hours, compared to the old bulb's average lifetime of 1,200 hours, suggests that the engineer's design improvement was successful in making the bulb last longer.

However, it's important to note that while the effect is statistically significant, the practical significance may be less clear. A difference of 0.2 hours may not make a noticeable impact on the bulb's usefulness or longevity in real-world scenarios. Additionally, other factors such as cost or energy efficiency may also need to be considered when evaluating the success of the new design.

The activity ratio in the value stream measures the efficiency of the production process by evaluating the ratio of value-added activities to non-value-added activities.

The activity ratio is a performance metric used in value stream mapping, which is a lean management tool for analyzing and improving the flow of materials and information in a production process.

It focuses on distinguishing value-added activities, which directly contribute to meeting customer requirements, from non-value-added activities, which do not add value but consume resources and time.

By calculating the activity ratio, organizations can assess the proportion of time and resources spent on value-added activities versus non-value-added activities.

A higher activity ratio indicates that a greater portion of resources is dedicated to value-added activities, indicating improved efficiency and reduced waste.

Conversely, a lower activity ratio suggests a higher proportion of resources being utilized for non-value-added activities, indicating potential areas for improvement and waste reduction.

The activity ratio serves as a valuable diagnostic tool for organizations to identify process inefficiencies, bottlenecks, and areas for improvement. By analyzing the activity ratio, organizations can streamline their processes, eliminate waste, and optimize resource allocation to enhance overall productivity and customer value.
