Answer:

273/4

Step-by-step explanation:

We know

A company’s stock opened at 68 3/8 dollars per share

68 3/8 = 547/8

The stock dropped 1 7/8 dollars on Monday

1 7/8 = 15/8

547/8 - 15/8 = 532/8

The stock dropped another 2 1/2 dollars on Tuesday.

2 1/2 = 5/2

532/8 - 5/2 = 532/8 - 20/8 = 512/8

On Wednesday, the stock gained back 4 1/4 dollars.

4 1/4 = 17/4

512/8 + 17/4 = 512/8 + 34/8 = 546/8

546/8 = 273/4

So, the answer is 273/4

Answer:

140 toy cars

Step-by-step explanation:

The ratio of Ed's toy car to Pete's toy car is initially given as 5:2

Ed gave Pete a total number of 30 cars

Let x represent the greatest common factor that exists between both number

Number of Ed's car is represented as 5x

Number of Pete car is represented as 2x

Since they each have an equal number of cars which is 30 then we can solve for x as follows

5x-30=2x+30

Collect the like terms

5x-2x= 30+30

3x= 60

Divide both sides by the coefficient of x which is 3

3x/3=60/3

x=20

Ed's car is 5x, we substitute 20 for x

5(20)

= 100 cars

Pete car is 2x,we substitute 20 for x

2(20)

= 40 cars

Therefore, the total number of cars can be calculated as follows

= 100+40

= 140 toy cars

Hence they have 140 toy cars altogether

Answer:

There are approximately 2/3 pounds of clay in one bowl.

Step-by-step explanation:

To find the number of pounds of clay in one bowl, you need to divide the total weight of clay (22 and 2/3 pounds) by the number of bowls (34).

To perform the calculation, we first need to convert the mixed number 22 and 2/3 to an improper fraction.

22 and 2/3 can be written as (3 * 22 + 2) / 3 = (66 + 2) / 3 = 68 / 3.

Now, we can calculate the weight of clay in one bowl by dividing the total weight by the number of bowls:

Weight of clay in one bowl = (Weight of clay) / (Number of bowls)

= (68 / 3) / 34

= 68 / (3 * 34)

= 68 / 102

= 2 / 3

Surface area is increasing at a rate of 502.654 cm^2/sec and volume is increasing at a rate of 2513.274 cm^3/sec.

Part A: To find the rate at which the surface area of the spherical balloon is increasing when the radius is 10 cm, we need to use the formula for the surface area of a sphere.

The formula for the surface area of a sphere is A = 4πr^2, where A is the surface area and r is the radius of the sphere.

Given that the radius is increasing at a constant rate of 2 cm/sec, we can differentiate the surface area formula with respect to time to find the rate of change of the surface area.

dA/dt = 8πr(dr/dt)

In this case, dr/dt is the rate at which the radius is increasing, which is 2 cm/sec. Plugging in the values, we get:

dA/dt = 8π(10)(2) = 160π cm^2/sec

Now, to round to the nearest thousandths, we can approximate π as 3.14159.

So, the surface area is increasing at a rate of approximately 502.654 cm^2/sec when the radius is 10 cm.

Part B: To find the rate at which the volume of the spherical balloon is increasing when the radius is 10 cm, we need to use the formula for the volume of a sphere.

The formula for the volume of a sphere is V = (4/3)πr^3, where V is the volume and r is the radius of the sphere.

Again, we can differentiate the volume formula with respect to time to find the rate of change of the volume.

dV/dt = 4πr^2(dr/dt)

Using the given values, we have:

dV/dt = 4π(10)^2(2) = 800π cm^3/sec

Approximating π as 3.14159, we can calculate the rate of change of the volume:

dV/dt ≈ 800(3.14159) ≈ 2513.274 cm^3/sec

Therefore, the volume is increasing at a rate of approximately 2513.274 cm^3/sec when the radius is 10 cm.

This answers the question: "The following questions are about a spherical balloon that is being filled with air such that its radius is increasing at a constant rate of 2 cm/sec.

Part A: How fast is the surface area increasing when the radius of the sphere is 10 cm? Round to the nearest thousandths.

Part B: How fast is the volume increasing when the radius is 10 cm? Round to the nearest thousandths."

The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.

A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.

The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.

The  area of Henry's flower bed would be 2500 square feet.

Let's start by finding the perimeter of Henry's flower bed since we know that he wants it to be a square. If we let s be the length of one side of the square, then the perimeter would be:

4s = 200

Simplifying this equation, we get:

s = 50

So Henry's flower bed will have sides of 50 feet each.

To find the area of the flower bed, we can use the formula:

Area = side^2

So in this case, the area would be:

Area = 50^2 = 2500 square feet

Therefore, the area of Henry's flower bed would be 2500 square feet.

Answer:

The perimeter of a parallelogram is 30cm.

Step-by-step explanation:

From the question , the given area of a parallelogram is 36 cm².

But the area of a parallelogram can be calculated using below formula

Area = base * height

From the question the distances that exist between the point of intersection of the diagonals and the sides are 2cm and 3cm respectively

There is the same distance between point of intersection of the diagonals and the opposite sides then,

The base of the side with 4cm can be calculated as

ha= 2+ 2= 4cm

But area can be calculated as A= base × height

36= b1 × h1

36=b1 × 4

b1= 9cm

The base of the other side can be calculated with 6cm height

h2= 3+3=6cm

A= b2× h2

36= b2 ×h2

36= b2× 6

b2= 6cm

Then the perimeter of the parallelogram can be calculated as

P= 2(b1 + b2)

= 2(6+9)

= 30cm

Hence,the perimeter of the parallelogram is 30cm

Answer:

f(x) = -½x + 16

Step-by-step explanation:

Using two points in the line, (0, 16) and (4, 14), we can write an equation for the linear function in the slope-intercept form, f(x) = mx + b, by finding the slope (m) and the y-intercept (b), then substituting each of the value into f(x) = mx + b.

✔️Slope (m) = change in y/change in x

Using, (0, 16) and (4, 14),

Slope (m) = (14 - 16)/(4 - 0) = -2/4

m = -½

✔️y-intercept (b) would be the value of y when x = 0, or the point at which the y-axis is intercepted by the line.

Thus,

When x = 0, y = 16

Therefore,

b = 16

✅Write the equation of the function by substituting m = -½ and b = 16 into f(x) = mx + b

Thus:

f(x) = -½x + 16

Total number of students = 10

To find:

How many was can you award first, second, and third place?

Solution:

Total number of students is 10. So, the total possible ways for the first award is 10.

We know that one student can hold only one place. So, after giving the first award, the number of remaining students is 9 and the total possible ways for the second award is 9.

Similarly, the total possible ways for the third award is 8.

Now, the total number of ways to award first, second, and third place is:

\(10\times 9\times 8=720\)

Therefore, the total number of ways to award first, second, and third place is 720.

The maximum value of the function y = 8(x^2+1)^(1/2) - x on the interval [0,4] is approximately 29.658, which occurs at x = 4  and The minimum value of y is approximately 3.605, which occurs at x = 1/√15.

To find the maximum and minimum values of the function y = 8(x^2+1)^(1/2) - x on the interval [0,4], we will first take the derivative of the function and set it equal to zero to find the critical points. Then we will evaluate the function at those critical points and at the endpoints of the interval to find the maximum and minimum values.

First, we take the derivative of y with respect to x:

y' = 8(1/2)(x^2+1)^(-1/2)(2x) - 1

Simplifying, we get

y' = 4x(x^2+1)^(-1/2) - 1

Setting y' equal to zero and solving for x, we get

4x(x^2+1)^(-1/2) - 1 = 0

4x(x^2+1)^(-1/2) = 1

16x^2 = (x^2+1)

15x^2 = 1

x = ±(1/√15)

We check these critical points as well as the endpoints of the interval [0,4] to find the maximum and minimum values of y

y(0) = 8(0^2+1)^(1/2) - 0 = 8(1)^(1/2) = 8

y(4) = 8(4^2+1)^(1/2) - 4 ≈ 29.658

y(1/√15) = 8((1/√15)^2+1)^(1/2) - (1/√15) ≈ 3.605

Answer:

Area of the rhombus ABCD = 16 square units

Step-by-step explanation:

Area of a rhombus = \(\frac{1}{2}(\text{Diagonal 1})(\text{Diagonal 2})\)

From the graph attached,

Diagonal 1 = Distance between the points A and C

Diagonal 2 = Distance between the points B and D

Length of a segment between (x₁, y₁) and (x₂, y₂) = \(\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^2 }\)

Diagonal 1 (AC) = \(\sqrt{(4-0)^2+(-1+1)^2}\) = 4 units

Diagonal 2(BD) = \(\sqrt{(2-2)^2+(3+5)^2}\) = 8 units

Now area of the rhombus ABCD = \(\frac{1}{2}(\text{AC})(\text{BD})\)

                                                       = \(\frac{1}{2}\times 4\times 8\)

                                                       = 16 units²

Therefore, area of the given rhombus is 16 units².

Here's a sample program in C++ that satisfies your requirements:

```
#include
using namespace std;

int main() {
 int num;
 cout << "Enter an integer between 0 and 35: ";
 cin >> num;

 if (num <= 9) {
   cout << num << endl;
 } else if (num >= 10 && num <= 35) {
   char letter = static_cast('A' + num - 10);
   cout << letter << endl;
 } else {
   cout << "Invalid input." << endl;
 }

 return 0;
}
```

- The program prompts the user to input an integer between 0 and 35 using the `cout` and `cin` statements.
- The `if` statement checks whether the number is less than or equal to 9. If it is, it outputs the number using the `cout` statement.
- The `else if` statement checks whether the number is between 10 and 35 (inclusive). If it is, it calculates the corresponding letter using the ASCII value for 'A' and the given number. The `static_cast` statement converts the calculated value to a character. Finally, the program outputs the letter using the `cout` statement.
- The `else` statement handles the case when the input is outside the range of 0 to 35. It outputs an error message using the `cout` statement.
- The program ends with the `return 0` statement.
