Answer:

n(k + m) = number of fruits

Step-by-step explanation:

n(k + m)

Remember that the fruits combined would be k + m.

Then to find the total, you would need to multiply by the number of plates, which is n. Therefore, you would get n(k+m) to showcase the total amount of fruits on the table.

The numeric value of x at x = -2 is given as follows:

f(-2) = 9.

To obtain the numeric value of a function or of an expression, we substitute each instance of any variable or unknown on the function by the value at which we want to find the numeric value of the function or of the expression.

In this problem, we have a piece-wise function, which is a function with different definitions based on the input of the function.

x = -2 is less than 1, hence the definition at x = -2 is given as follows:

f(x) = -4x + 1.

The numeric value is then given as follows:

f(-2) = -4(-2) + 1

f(-2) = 9.

Neither the statement "W is not a subspace of R3 because it is not closed under addition" nor the statement "W is not a subspace of R3 because it is not closed under scalar multiplication" is valid.

The set W is an R3 subspace with ordinary operations. To demonstrate that W is a subspace of R3, we must demonstrate that it meets three subspace properties: (1) it includes the zero vector, (2) it is closed under addition, and (3) it is closed under scalar multiplication.

Since W satisfies all three properties of a subspace, it is a subspace of R3 with the standard operations. Therefore, both statements "W is not a subspace of R3 because it is not closed under addition" and "W is not a subspace of R3 because it is not closed under scalar multiplication" are incorrect.

Answer:

95.2 kg

Step-by-step explanation:

A shop sells potatoes and carrots

let c = carrots

let p = potatoes

let TW = Total weight

The shop orders 50.4 kg more potatoes than carrots

p = 50.4 kg + c

Total weight = Mass of p + Mass of c

TW = 50.4 kg + c + c = 50.4 kg + 2c ....... (i)

32% of the total weight is carrots

c = (32 /100 )  * Total weight = 0.32 TW

TW = c / 0.32 ....... (ii)

50.4 kg + 2c = c / 0.32

Multiply all through by 0.32

16.128 + 0.64c = c

c -  0.64c  = 16.128

0.36 c = 16.128

c = 16.128 / 0.36 = 44.8 kg

Potatoes = 50.4 kg + c = 50.4 kg + 44.8 kg = 95.2 kg

In a right triangle, the trigonometric ratio x must be positive. There isn't an x solution that meets the requirements. The cosine and sine function values given are incompatible with a correct right triangle. x = -0.40

A right triangle is one with a 90 degree inner angle. The two arms of a right angle are made up of height and base.

The sum of the angles B and C's measurements in a right triangle is 90 degrees (since angle A is 90 degrees).

So we have:

B + C = 90

And since sin C = 3x + 0.31, we know that:

C = sin⁻¹(3x + 0.31)

B + sin⁻¹(3x + 0.31) = 90

Subtracting sin⁻¹(3x + 0.31) from both sides, we get:

B = 90 - sin⁻¹(3x + 0.31)

Now we can use the fact that cos B = x - 0.49:

cos(90 - sin⁻¹(3x + 0.31)) = x - 0.49

Using the identity cos(90 - θ) = sin(θ), we can rewrite this as:

sin(sin⁻¹(3x + 0.31)) = x - 0.49

Simplifying the left side using the inverse sine function, we get:

3x + 0.31 = x - 0.49

Subtracting x and 0.31 from both sides, we get:

2x = -0.80

Dividing both sides by 2, we get:

x = -0.40

Answer:

1. Increased

2. 70%

Step-by-step explanation:

The trend show that the percentage of the people in the town (Using coffee shop) increased during the period.

Prediction will be 70% users

H (4.84) will be the correct answer

Answer: You are correct. The answer is choice (H) 4.84

======================================================

Explanation:

10% = 10/100 = 0.1

10% of 4.4 = 0.1*4.4 = 0.44

Increasing 4.4 by 10% means we add on 0.44 to get 4.4+0.44 = 4.84

So the ruler says 4.4 inches but the actual table could be as long as 4.84 inches.

---------

A shortcut is to compute it like this:

4.4*1.1 = 4.84

The multiplier 1.1 represents an increase of 10% because

1.1 = 1 + 0.1 = 100% + 10%

This shortcut allows for multiple percentage increases that can be chained together fairly quickly.

The expected number of boys who make good score is found to be 188 by using random sample method.

To get the projected number of boys who get good grades, multiply the total number of boys by the proportion of boys who answered they would like to get good grades the most.

According to the table, the total number of boys surveyed is:

188 +64 +192 = 444

And the percentage of guys who indicated they

would like to get good grades is:

188/444 0.423

As a result, the projected number of guys with good grades is:

Expected number of boys = total number of boys

x percentage of boys who get high grades

444 x 0.423 = 444 boys expected

Number of boys expected = 187.812

When we round to the nearest full number, we get: The expected number of males with good grades

is 188.

So, as a result there are 188 boys who say they

would like to score more good grades.

The height of the cylinder is approximately 5.97 cm.

A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases and a curved lateral surface that connects the bases. The bases are perpendicular to the lateral surface, which means that the lateral surface forms a curved rectangle.

Given;

The circumference of the cylinder is 32π.

The lateral surface area of the cylinder is 750 cm².

Lateral surface area of a cylinder = 2πrh

Circumference of a cylinder = 2πr

We can use the circumference formula to find the radius of the cylinder:

2πr = 32π

r = 16

Now we can use the lateral surface area formula to find the height of the cylinder:

750 = 2π(16)(h)

750 = 32πh

h = 750/(32π)

h ≈ 5.97

As a result, the cylinder's height is around 5.97 cm.

Answer:

Step-by-step explanation:

The candy store will use 103 grams of sugar in 10 hours.

To find out how many grams of sugar the store will use in 10 hours, we can simply multiply the amount of sugar used in one hour (10.3 grams) by the number of hours (10).

To solve the problem, we use a simple multiplication formula: the amount used per hour (10.3 grams) multiplied by the number of hours (10) to find the total amount of sugar used in 10 hours.

We can interpret this problem using a rate equation: the rate of sugar usage is 10.3 grams/hour, and the time period is 10 hours. Multiplying the rate by the time gives the total amount of sugar used.

So the calculation would be:

10.3 grams/hour x 10 hours = 103 grams

Therefore, the candy store will use 103 grams of sugar in 10 hours.

(a) The answer is 360, and the problem involves a permutation.

(b) The answer is 45, and the problem involves a combination.

(a) This problem involves a permutation because the order of the digits matters. We need to determine how many 4-digit numbers can be formed without repetition from the given digits.

The number of choices for the first digit is 6 (since any of the 6 digits can be chosen). For the second digit, we have 5 choices remaining, then 4 choices for the third digit, and finally 3 choices for the fourth digit.

Therefore, the total number of 4-digit numbers without repetition is:

6 * 5 * 4 * 3 = 360

So, there are 360 different 4-digit numbers that can be made.

(b) This problem involves a combination because the order of the questions does not matter. We need to determine how many different choices the student has to answer 8 out of 10 questions on the exam.

The number of different choices can be calculated using the combination formula. The formula for combinations is:

nCr = n! / (r! * (n-r)!)

where n is the total number of items, and r is the number of items to be selected.

In this case, n = 10 (total number of questions) and r = 8 (number of questions to be answered).

Plugging the values into the formula, we have:

10C8 = 10! / (8! * (10-8)!)

10C8 = 10! / (8! * 2!)

10C8 = (10 * 9) / (2 * 1)

10C8 = 45

So, there are 45 different choices the student has to answer 8 out of 10 questions on the exam.
