Answer:

I think the answer is 6x20, beaches you simply do: 6x40

6x(10+10+20), so: 6x10+6x10+60x20

Answer:

\(6*40 = (6*10) + (6*10) + (6*20)\)

Step-by-step explanation:

1. \(6*40=240\)

2. \(6*10+6*10=120\)

3. \(240=120+x\)

4. \(240-120=120\)

5. \(120=6*20\)

6. \(6*20\)

So, you have to fill in 6x20 in the gap.

The tree will be 75 feet tall when it will be fully grown.

The total tree height is the distance between the tree's base and its highest point on the ground. A yardstick provides a quick and relatively accurate way to gauge the height of a tree.

If the tree is currently 60 feet tall and is approximately 80% of its full height, we can assume that the tree will be 100% of its full height when it is fully grown. To determine the full height of the tree, we can use the proportion:

60 feet / 80% = X feet / 100%

We can then cross-multiply to solve for X:

X = (60 feet * 100%) / 80%

= 75 feet

So, when the tree is fully grown, it will be approximately 75 feet tall.

Answer: total cost of the stuff she buys ≤ 18 since she only has 18 dollars to buy stuff

Step-by-step explanation:

let's add up the cost of the stuff she buys:

- a flat cost of $6.50

- a savings of $5.75 (she's technically not spending money but we can count this as part of her expenses since it's taking away from the 18 dollars)

- some number (x) candy bars. if each candy bar costs $1.15 then the money she spends on candy bars is $1.15

with that being said:

6.50 + 5.75 + 1.15x ≤ 18

solve for x

since we are talking about whole # candy bars, if you get a decimal from this, round down to the nearest whole #

Answer:

Andrea can buy 5 candy bars.

Step-by-step explanation:

First to solve this we will subtract 6.50 from 18 because Andrea already spent that money. Then we must subtract 5.75 from 18 because Andrea can't spend that money. All the subtracting equals 5.75. After that we can divide the remaining money by 1.15 to see how many candy bars we can buy which equals 5. Finally the answer is that Andrea can buy 5 candy bars.

(a) f(x) = 10x - x^2 is concave

(b) f(x) = x' + 6x^2 + 12x is convex

(c) f(x) = 2x - 3x^2 is concave

(d) f(x) = x + x is neither convex nor concave

(e) f(x) = x + x^4 is convex

(a) The function f(x) = 10x - x^2 is concave. To show this, we take the second derivative of f(x) which is -2, which is negative for all x. Since the second derivative is negative for all x, the function is concave.

(b) The function f(x) = x' + 6x^2 + 12x is convex. To show this, we take the second derivative of f(x) which is 12x + 2, which is positive for all x. Since the second derivative is positive for all x, the function is convex.

(c) The function f(x) = 2x - 3x^2 is concave. To show this, we take the second derivative of f(x) which is -6, which is negative for all x. Since the second derivative is negative for all x, the function is concave.

(d) The function f(x) = x + x is neither convex nor concave. To show this, we take the second derivative of f(x) which is 0, which is neither positive nor negative. Since the second derivative is neither positive nor negative, the function is neither convex nor concave.

(e) The function f(x) = x + x^4 is convex. To show this, we take the second derivative of f(x) which is 12x^2, which is positive for all x except 0. Since the second derivative is positive for all x except 0, the function is convex.

Answer:

Nicholas can order up to 3 toppings.

Step-by-step explanation:

Solve for the tip:

15% of the total cost = 15% × $7.50

Convert percentage into a decimal:

0.15 × 7.50 = 1.125

Variable x = number of toppings

Set up an equation:

7.50 + 1.125 + 1.25x = 13

Combine like terms:

8.625 + 1.25x = 13

1.25x = 4.375

x = 3.5

Since it is impossible to order "half" of a topping (0.5), Nicholas can only order up to 3 toppings.

The discriminant of ggg is negative.

The discriminant is a term used in mathematics to determine the nature of the solutions of a quadratic equation. For a quadratic equation in the form ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac. If the discriminant is negative, it means that the quadratic equation has no real solutions. In the context of ggg, since the discriminant is negative, it indicates that the quadratic equation associated with ggg does not have real solutions. This could imply that ggg is not a quadratic expression or that it represents a quadratic expression with complex solutions.

The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.

We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.

The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.

First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.

z1 = 2,000 / 5,000 = 0.4.

Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.

z2 = 5,000 / 5,000 = 1.

Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.

Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.

Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.

Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.

So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

For a 7 times 8 matrix A; dim Nul A = 6 and Col A does not span R^2, but at most a two-dimensional subspace of R^7.

To determine the dimension of the null space (Nul) of matrix A, we can use the rank-nullity theorem, which states that the dimension of the null space plus the dimension of the column space (Col) equals the number of columns of the matrix.

In this case, we have a 7x8 matrix A with two pivot columns.

The pivot columns are the columns in the matrix that contain leading non-zero entries in a row reduced echelon form.

Since there are two pivot columns, it means that there are two leading non-zero entries in the row reduced echelon form of matrix A.

The remaining 8 - 2 = 6 columns are free columns, which do not contain pivot elements.

The dimension of the null space, dim Nul A, is equal to the number of free columns, which in this case is 6.

Therefore, dim Nul A = 6.

Regarding the column space of matrix A, Col A, it is not R^2 because the number of pivot columns represents the maximum number of linearly independent columns in the matrix.

In this case, there are two pivot columns, so the column space of matrix A can span at most a two-dimensional subspace of R^7, not R^2.

In order for a number to be divisible by 12, it must be divisible by both 3 and 4.
To be divisible by 3, the sum of the digits must be divisible by 3.
7 + 7 + 3 + 1 + 8 + 6 + 2 + d + e = 34 + d + e

Since 34 is not divisible by 3, we need d + e to be a multiple of 3 in order for the sum to be divisible by 3.
Possible values for d + e are 3, 6, and 9.

To be divisible by 4, the last two digits of the number must be divisible by 4.
Therefore, we need de to be a multiple of 4.

Possible values for de are 12, 16, 32, 36, 52, 56, 72, 76, and 92.
Out of these, only 12, 36, 52, and 76 have a sum of digits that is a multiple of 3.

So the possible values for de are 12, 36, 52, and 76.

The complete question is:

In the previous modules we developed formulas, tables, and graphs to represent how two varying quantities change together. For example, we considered how Kristin's height above the ground changed as her total distance traveled increased while riding a Ferris wheel.

We even assigned letters to represent the possible varying values each quantity can assume.

• Let d represent the distance Kristin has traveled (in meters) around the Ferris wheel starting at the bottom.

• Let h represent Kristin's height above the ground (in meters).

Note that the way we are thinking about this relationship is that we vary Kristin's distance traveled and observe what happens to her height above the ground.

What if you want to communicate information about her position after she traveled some number of feet? You could write it out in words, like "Kristin was 16.3 meters above the ground when she had traveled 23.7 meters around the Ferris wheel". However, that's a lot to have to write out, especially if you want to talk about multiple values. You could also draw a table or create a graph, but mathematicians developed a tool called function notation to help them represent values in a covarying relationship.

[Note: We will define the exact meaning of "function" later in this investigation. For now, just think of "function" as meaning the same thing as "relationship".]

First, we pick a letter to represent the name of the relationship. Let's call this relationship "f". Now, instead of saying "the relationship between Kristin's height above the ground (in meters) and her total distance traveled (in meters)" we can simply say "relationship f".

Also, we can use f(d) to represent values of Kristin's height above the ground (values of h). We read this as "f of d", and the parentheses here are just part of the notation. They do NOT indicate multiplication.

For example, f(13) represents Kristin's height above the ground (in meters) when she has traveled 13 meters around the Ferris wheel.

Subject to:

x1 + x2 + x3 ≤ $1,500 (maximum disposable income)

x1 + x2 ≤ $1,100 (amount spent on food and shelter combined must not exceed $1,100)

x2 ≤ $800 (amount spent on shelter alone must not exceed $800)

x3 ≤ $400 (entertainment cannot exceed $400)

Using Excel Solver:

In Excel, set up a spreadsheet with the following columns:

Answer : The length of QT is 19.

Step-by-step explanation :

As we are given:

Length of RT = 11

Length of RS = 8

As we are given that R is the mid-point of line QS. That means,

Length of RS = Length of QR = 8

Now we have to calculate the length of ST.

Length of ST = Length of RT - Length of RS

Length of ST = 11 - 8

Length of ST = 3

Now we have to calculate the length of QT.

Length of QT = Length of QR + Length of RS + Length of ST

Length of QT = 8 + 8 + 3

Length of QT = 19

Therefore, the length of QT is 19.
