A rectangle has side lengths (x+4) feet and (2x+1) feet for x > 0. Write a function that describes the area A, in square feet, in terms of x.


A.) A(x) = 3x+5

B.) A(x) =6x+10

C.) A(x) =2x(squared by 2) +9x+4

D.) A(x)= 2x(squared by 2) +7x-4

Answer:

The correct answer is A.

Step-by-step explanation:

The correct answer is A.

To find the length of one side of the square, we need to take the square root of the area. Therefore, the square root of 90 is approximately 9.49 feet. Since this value falls between 9 feet and 10 feet, but is closer to 9 feet, the statement "√90 feet is between 9 feet and 10 feet but is closer to 9 feet" is true. So, Jimmy should cut the carpet to 9.49 feet to fit the square-shaped room.

The volume of the oblique cylinder can be calculated as:

833π cm³

The formula that would be used to find the volume of any given oblique cylinder can be expressed as:

Volume = πr²h, where:

radius of the cylinder = r

height of the cylinder = h

π is a constant

We are given the values for the cylinder as:

r = 14/2 = 7 cm

h = 17 cm

Volume of the oblique cylinder =  πr²h =  π × 7² ×  17

Volume of the oblique cylinder = 833π cm³

Answer:

6x-50-7(3x+10)=0

Distribute the -7:

6x - 50 - 21x - 70 = 0

The summation ∑₁¹²⁴(29a₁ - 13b₁)  = -30

Suppose that ∑₁¹²⁴a₁ = -10 and  ∑₁¹²⁴b₁ = -20. We desire to compute the following ∑₁¹²⁴(29a₁ - 13b₁), we proceed as follows.

So, the summation ∑₁¹²⁴(29a₁ - 13b₁)

Expanding the brackets, we have that

∑₁¹²⁴(29a₁ - 13b₁) = ∑₁¹²⁴29a₁ -  ∑₁¹²⁴13b₁)

= 29∑₁¹²⁴a₁ -  13∑₁¹²⁴b₁

Given that ∑₁¹²⁴a₁ = -10 and  ∑₁¹²⁴b₁ = -20.

So, substituting the values of the variables into the equation, we have that

∑₁¹²⁴(29a₁ - 13b₁) = 29∑₁¹²⁴a₁ -  13∑₁¹²⁴b₁

= 29(-10) - 13(-20)

= -290 + 260

= -30

So, ∑₁¹²⁴(29a₁ - 13b₁)  = -30

John Singer Sargent repainted the right strap on Madame X (1883-1884). The Option C is correct.

Madame X caused a scandal when it was first exhibited in Paris in 1884. Sargent had originally painted the right strap of the dress hanging off the shoulder which was seen as too provocative at the time.

However, he later repainted the strap to be more securely in place, but this change did not entirely satisfy critics, but, nevertheless, the painting is now considered a masterpiece and an iconic example of Sargent's style.

Answer:

Step-by-step explanation:

If the large Jar is $4.10 for 540g

and  small jar  $2.81 for 360 g

You need to show how much it cost for 1 g,so you can compare how much it cost per gram. You would divide the total cost by the grams to see how much it is for 1 g.

Large jar.   $4.10/540 = $.0076  for 1 gram

Small Jar.   $2.81/360 =$.0078 for 1 gram

Because the large jar is cheaper to buy per gram, the large jar is the best value for the money.

The ratio of Student Ambassadors to total Students in Mr. Thompson's class is 1:4.

Ratios and proportions are two fundamental concepts in mathematics that are used to compare quantities and express relationships between them.

A ratio is a comparison of two quantities that are expressed in the same units. Ratios are typically written in the form of "a:b" or "a to b", where a and b are two quantities being compared. For example, the ratio of the number of boys to the number of girls in a class of 20 students might be 3:2, indicating that there are 3 boys for every 2 girls.

A proportion is a statement that two ratios are equal. Proportions are used to solve problems involving ratios by setting up an equation that equates two ratios.

The total number of students in Mr. Thompson's class is 6 + 18 = 24.

The ratio of Student Ambassadors to total Students is 6:24, which can be simplified by dividing both the numerator and denominator by 6 to get 1:4.

Therefore, the ratio of Student ambassadors to total Students in Mr. Thompson's class is 1:4.

Answer:

C.  ∠B ≅∠E

Step-by-step explanation:

Since ΔJAB ≅ ΔFED, their corresponding angles are congruent.

Therefore:

Given that m∠BJA = 52° and m∠EDF = 65°, then:

Therefore, m∠ABJ = 65°.

Interior angles in a triangle sum to 180°. Therefore:

⇒ m∠JAB + m∠BJA + m∠ABJ = 180°

⇒ m∠JAB + 52° + 65° = 180°

⇒ m∠JAB + 117° = 180°

⇒ m∠JAB = 63°

As m∠JAB = m∠FED, then m∠FED = 63°.

Since ΔJAB ≅ ΔFED, their corresponding sides are congruent.

Given that AB = 10 inches, then ED = 10 inches.

Answer:

The equation that shows how the cost of the baby shower, y, depends on the number of guests, x is:

y = 9x + 43

In this equation, x represents the number of guests and y represents the cost of the baby shower. The term 9x represents the cost of food for each guest, multiplied by the number of guests. The term 43 represents the cost of decorations that has already been spent. Therefore, the total cost of the baby shower can be calculated by multiplying the number of guests by the cost of food per guest and adding the cost of decorations that have already been spent.

Answer: y = 9x + 43

Step-by-step explanation: y =  cost of the baby shower

x = number of guests

$9 per guest would be 9x

Answer:

(x + 1)² + y² = 3

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (- 1, 0 ) and r = [tex]\sqrt{3}[/tex] , then

(x - (- 1) )² + (y - 0)² = ([tex]\sqrt{3}[/tex] )² , that is

(x + 1)² + y² = 3

By the theorem of triangles, the calculated value of y in the triangle ABC is 50 degrees

From the question, we have the following parameters that can be used in our computation:

The triangle ABC

Also, the angles in the triangle are given as y, y and 80 degrees

By the theorem of triangles, the sum of angles in a triangle is 180 degrees

Representing the above statement as an equation, we have

y + y + 80 = 180

Evaluate

y = 50

So, we can conclude that the value of y is 50 degrees

According to the information, the least number of committees that need to be formed to meet all of the conditions is 8.

To minimize the number of committees, we can try to use each student in as many committees as possible. Since each student must be in exactly 2 committees, and there are 12 students, we need a total of 24 "student committee slots".

Now we need to figure out how to assign the students to committees so that no two committees have more than one student in common. One way to do this is to use a "round-robin" approach:

Assign the first student to committees 1, 2, and 3.

For the next student, assign them to committees 1, 4, and 5.

For the third student, assign them to committees 2, 4, and 6.

Continue in this way, cycling through the remaining students and assigning them to three committees at a time, making sure to avoid any duplicates.

After assigning all 12 students to committees in this way, we will have a total of 8 committees. We can check that each committee contains exactly 3 students, and that no two committees have more than one student in common.

Using the correct measure of center, the team that typically has the tallest players is C. The Champs, with a mean of about 66.4 inches.

The three typical measures of center are the mean, the median, and the mode.

The mean is the average value, obtained as the quotient of the total value of the data set divided by the number of items.

The median is the middle value of the data set arranged in descending or ascending order.

The mode refers to the value that occurs most in the data set.

66 66 66 = 198

63 63 63 = 189

65 65 65 = 195

64 64 64 = 192

58 58 58 = 174

Total =      948

Mean = 63.2 (948 ÷ 15)

Median = 64 (58, 58, 58, 63, 63, 63, 64, 64, 64, 65, 65, 65, 66, 66, 66)

For any matrices A and B, where A is a m x n matrix and B is a n x p matrix, the inequality rank(AB) ≤ min rank(A), rank(B) holds.

To see why this is so, examine the rank of a matrix, which is defined as the matrix's greatest number of linearly independent rows or columns.

In other words, it is the dimension of the vector space covered by the matrix's rows or columns.

When we multiply matrices A and B to obtain AB, we get a matrix with m rows and p columns.

The dot product of a row from A and a column from B yields each element in the matrix.

Because the rows and columns of AB are linear combinations of the rows and columns of A and B, the rank of AB is at most the minimum of the rank of A and the rank of B.

If either A or B has a lower rank than the other, there will be some linear dependency between the rows or columns of one of the matrices, which will carry over to AB. This indicates that AB's rank will be strictly less than the bigger matrix's rank.
