Answer: She need 14 visits to reach 90 points

Step-by-step explanation:

Let y be the number of points and v be the number of visits

We will have an equation

y= 2.5v + 55

Now we want to find the number of visits she needs to reach 90 points; we put 90 in the y.

90 = 2.5v +55

Subtracted 55 from both sides

35 = 2.5v

Divided both sides by 2.5

v= 14 visits

So she need 14 visits to reach 90 points

By subtracting the cost of goods sold form the net sales, the gross profit = $439000.

Gross profit is a financial measure that represents the difference between a company's net sales and the cost of goods sold. It is a key indicator of a company's profitability and can be used to assess the efficiency of the company's operations.

The formula for calculating gross profit is:

Gross profit = net sales - cost of goods sold

Gross profit = net sales - cost of goods sold

Gross profit = $732400 - $293400

Gross profit = $439000

Therefore, the gross profit of the company is $439000.

Answer:

1) N = M - L

Step-by-step explanation:

Given equation,

→ L = M - N

Now the value of N will be,

→ L = M - N

→ M - N = L

→ -N = L - M

→ N = -L + M

→ [ N = M - L ]

Hence, value of N is M - L.

To find the equation of the line that passes through the point (1, 2) and is perpendicular to the line y=3x-1, we can first find the slope of the line y=3x-1. The slope of this line is 3, so a line perpendicular to it will have a slope of -1/3. We can then use the point-slope form of the line to write the equation of the line that passes through (1,2) and has a slope of -1/3. The point-slap form of a line is given by y-y₁ = m(x-x₁), where (x₁,y₁) is a point on the line and m is the slope of the line. Plugging in the coordinates of the point (1,2) and the slope -1/3, we get the equation y-2 = -1/3(x-1), which simplifies to y-2 = -x/3 + 1/3. Multiplying both sides of the equation by 3 to get rid of the fractions, we get 3y-6 = -x+1. Finally, we can move all the terms to one side of the equation to get the standard form of the line: 3y-x-5 = 0. Therefore, the equation of the line that passes through the point (1, 2) and is perpendicular to the line y = 3x - 1 is x-3y-5=0, so the correct answer is A.

The point F( – 4, – 1) i rotated 270° counterclockwie around the origin. then The coordinates of the point F' is (-1 ,4 )

Given that the point J(-2,1) is rotated about 270° about the origin.

Coordinates of the resulting point F':

Since, we know that, when rotating a point 270° counterclockwise about the origin, the point (x,y) becomes (y,-x) which means we switch the places of x and y coordinates and make x as negative.

Therefore, the transformation is given by

(x ,y) -> ( y , -x)

Using the above transformation, we have,

(-4 ,-1) ⇒ ( -1 , -(-4)) ⇒ (-1 , 4)

Therefore, the resulting point of the coordinates of the point F' is (-1 ,4)

Answer:

The possible values of t for which the rocket's height is 12 meters are approximately 1.1 or -1.1.

Step-by-step explanation:

12 = 35t - 5t^2

t = (-b ± √(b^2 - 4ac)) / 2a

t = (35 ± √(35^2 - 4(-5)(-12))) / 2(-5)

t = (35 ± √(35^2 + 240)) / -10

t = (35 ± √575) / -10

t = (35 + √575) / -10 = (35 + 24) / -10 = 11/10 = 1.1

t = (35 - √575) / -10 = (35 - 24) / -10 = -11/10 = -1.1

The rocket's height is 12 meters at time t = 0.4 seconds.

Two or more expressions with an Equal sign is called as Equation.

A model rocket is launched with an initial upward velocity of 35 m/s.

The rocket's height h (in meters) after t seconds is h=35t-5t

We have to find the time(s) when the rocket's height is 12 meters, we need to solve the equation:

h = 35t - 5t = 30t

We want to find all values of t that make h = 12. So we set h = 12 and solve for t:

12 = 30t

Divide both sides by 30

t = 12/30

t = 0.4

Therefore, the rocket's height is 12 meters at time t = 0.4 seconds.

Answer:

Large box: 18.5 kg

Small box: 13.75 kg

Step-by-step explanation:

Let  L represent a large box, and S represents a small box

We have the equation

3L + 2S = 83 kg

5L + 6S = 175 kg

We time the first equation by -3

-9L - 6S = - 249 kg

5L + 6S = 175 kg

Now Let's find the large box weighs first

Add both equation and we get

-4L = -74 kg

L = 18.5 kg

Now put 18.5 in for the L to find the weight of the small box

5(18.5) + 6S = 175 kg

92.5 + 6S = 175 kg

6S = 82.5 kg

S = 13.75 kg

Answer:

x as large; y as small

3 large + 2 small = 83    (1st equation)

5 large + 6 small = 175    (2nd equation)

3x + 2y = 83   (multiply by -5)

5x + 6y = 175   (multiply by 3)

-15x - 10y = -415

15x + 18y = 525      (simplify)

8y = 110

y = 13.75       (small box weight)

3x + 2y = 83       (substitute the value of y)

3x + 2(13.75) = 83

3x + 27.5 = 83

3x = 55.5

x = 18.5       (large box weight)

3x + 2y = 83

3(18.5) + 2(13.75) = 83

55.5 + 27.5 = 83

83 = 83          (1st equation is proven right)

5x + 6y = 175

5(18.5) + 6(13.75) = 175

92.5 + 82.5 = 175

175 = 175           (2nd equation is proven right)

therefore, large box weight is 18.5kg and the small box weight is 13.75kg.

5x and 3x are like terms because they both have the same variable being multiplied to them which is x.

The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.

What is the inequality equation?

Equations and inequalities are mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are supposed to be equal and shown by the symbol =. Whereas in inequality, the two expressions are not necessarily equal and are indicated by the symbols: >, <, ≤, or ≥.

To determine the minimum number of sets of glasses that Latanya should buy, we can set up the following inequality:

x * 6 + 390 >= 739

This inequality states that the number of glasses Latanya has after buying x sets of glasses should be greater than or equal to the minimum number of glasses the restaurant needs.

To solve for x, we can subtract 390 from both sides of the inequality to get:

x * 6 >= 739 - 390

x * 6 >= 349

x >= 349/6

x  >= 58.16

x >= 58

Hence, The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.

The dimension is d and d<n. Thus maximum number of linearly independent vectors that can draw from the set V1, V2....Vn is d.

First note that for "any vector space V, basis B of V is maximal linearly independent set in V". That is there is no other any linearly independent set which contains more than |B| number of elements on B. Let us consider this statement as 1. Two or greater vectors are stated to be linearly independent if none of them may be written as a linear mixture of the others. On the contrary, if at the least certainly considered one among them may be written as a linear mixture of the others, then they may be stated to be linearly dependent. Now here dimension is d and d<n. Thus maximum number of linearly independent vectors that can draw from the set V1, V2....Vn is d.

Thus, the maximum number = d

D) six and one third feet

Step-by-step explanation:

To find the total amount of wood that Harry needs, we need to find the total length of the three pieces of wood that are two and three fourths feet long and the total length of the six pieces of wood that are one and one third feet long.

The three pieces of wood that are two and three fourths feet long have a total length of 3 * 2 and 3/4 = 6 and 1/4 feet.

The six pieces of wood that are one and one third feet long have a total length of 6 * 1 and 1/3 = 8 and 2/3 feet.

To find the total length of all the pieces of wood, we need to add the total length of the three pieces that are two and three fourths feet long and the total length of the six pieces that are one and one third feet long. This gives us a total of 6 and 1/4 + 8 and 2/3 = 14 and 7/12 feet.

Therefore, Harry will need a total of 14 and 7/12 feet of wood for the project. This is equivalent to approximately six and one third feet, so the correct answer is d) six and one third feet.

0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations

To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.
