Answer:

Step-by-step explanation:

If there are 22 students and she has 24 pencils she would need to give each of them 1 pencil. 24-22= 2

The number of pencils will be left over after Mrs Blue has given each student the same number of pencils is 16 pencils.

Given that, Mrs Blue has eight packages of pencils that she wants to distribute evenly among her sixth grades students. There are 24 pencils in each package, and she has 22 students.

We need to find out how many pencils will be left over after Mrs Blue has given each student the same number of pencils.

The unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit. It is a method that we use for most of the calculations in math.

There are 24 pencils in each package and there are eight packages of pencils.

So, the total number of pencils=8×24=192

Now, she is distributing evenly among 22 students=192/22=8.72

Then, 8×22=176

Mrs Blue is distributing 8 pencils to each student.

Number of pencils left=192-176=16

Hence, the number of pencils will be left over after Mrs Blue has given each student the same number of pencils is 16 pencils.

The length is decreasing by 7 in/sec and the width is shrinking at 10 in/sec , so the total area will decreased by -98 in/sec

The area is the total measurement of all the space enclosed by a closed geometric figure.

Using the area of rectangle to find the formula for the area and the perimeter shows us..

A = L*W

P = 2L + 2W

dA/dt = L * dW/dt. + dL/dt * W

dP/dt = 2 * ( dL/dt + dW/dt )

We are given the following information...

L = 8 inches

W = 4 inches

dL/dt = -7 in/sec ( decreasing so the sign is negative )

dW/dt = -10 in/sec ( decreasing so the sign is negative )

dA/dt =  L * dW/dt. + dL/dt * W

Answer:

The equation that represents the line that passes through the given points is y - 1 = \(\frac{5}{3}\) (x - 3) ⇒ A

Step-by-step explanation:

The point-slope form of the linear equation is y - y1 = m(x - x1), where

The rule of the slope is m = \(\frac{y2-y1}{x2-x1}\) , where

∵ The line passes through points (3, 1) and (6, 6)

∴ x1 = 3 and y1 = 1

∴ x2 = 6 and y2 = 6

→ Substitute them in the rule of the slope to find it

∵ m = \(\frac{6-1}{6-3}=\frac{5}{3}\)

∴ m = \(\frac{5}{3}\)

→ Substitute the value of x1, y1, and m in the form of the equation above

∵ y - 1 = \(\frac{5}{3}\) (x - 3)

∴ The equation that represents the line that passes through the given

   points is y - 1 = \(\frac{5}{3}\) (x - 3)

The coordinates of the point closest to the origin are x = -1, y = 0, and z = 1.

To find the coordinates of the point (x, y, z) on the plane z = 1x + 1y + 2 that is closest to the origin, we can minimize the square of the distance from the origin to the point (x, y, z). The square of the distance, D², can be expressed as:

D² = x² + y² + (1x + 1y + 2 - 0)²

Taking partial derivatives with respect to x, y, and z and setting them to zero, we can find the critical points:

∂(D²)/∂x = 2x + 2(1x + 1y + 2)(1) = 0
∂(D²)/∂y = 2y + 2(1x + 1y + 2)(1) = 0

Solving these equations simultaneously:

x + y + 1 = 0
x = -y - 1

Substituting x into the equation for z:

z = 1(-y - 1) + 1y + 2
z = -y - 1 + y + 2
z = 1

So, the coordinates of the point closest to the origin are:
x = -1
y = 0
z = 1

The approximate chi-square value for this study is 10.84.

In a brand awareness study involving 35 males and 35 females, 25 males and 15 females identified the brand correctly.

To find the chi-square value, we need to create a contingency table and apply the chi-square formula. Here's a quick breakdown of the process:

1. Create a contingency table:
       Males    Females
Correct    25          15
Incorrect  10          20

2. Calculate row and column totals:
       Males    Females    Total
Correct    25          15          40
Incorrect  10          20          30
Total         35          35          70

3. Find the expected frequencies for each cell by multiplying row and column totals and dividing by the overall total (for example, for the 'Correct Males' cell, multiply 40*35 and divide by 70):
       Males    Females
Correct    20          20
Incorrect  15          15

4. Apply the chi-square formula: Χ² = Σ[(Observed-Expected)²/Expected]
Χ² = [(25-20)²/20] + [(15-20)²/20] + [(10-15)²/15] + [(20-15)²/15]
Χ² ≈ 5 + 2.5 + 1.67 + 1.67
Χ² ≈ 10.84

The total number of coins Latanya has if she has 90 nickels and 150 pennies is 240.

The total number of coins Latanya has if she has n nickels and p pennies is n + p.

Latanya finds some nickels and pennies under the couch cushions.

Latanya has 90 nickels and 150 pennies.

Therefore, the number of coins she has can be calculated as follows:

number of nickels = 90

number of pennies = 150

Therefore,

total number of coins = 150 + 90

total number of coins = 240

If she has n nickels and p pennies, the total coins can be calculated as follows:

number of nickels = n

number of pennies = p

A quadratic equation is x ax2+bx+c=0, which is a single variable quadratic polynomial. a 0. Because this polynomial is of second order, the Basic Theorem of Algebra implies that it has at least one solution. Simple or complex solutions are possible. A quadratic equation is a quadratic equation. This means it has at least one word that must be squared. One of the most common solutions for quadratic equations is "ax2 + bx + c = 0." where a, b, and c are numerical coefficients or constants. where the variable "X" is unnamed.

So, we can set h(t) = 0 and solve for t:

\(0 = t^2 + 3t - 18\\t = (-3 + \sqrt (3^2 - 4(1)(-18))) / (2(1))\\t = (-3 + \sqrt (81)) / 2\\t = (-3 + 9) / 2\\\)

Answer:

p = 16

Step-by-step explanation:

Given p is directly proportional to (q + 2)² then the equation relating them is

p = k(q + 2)² ← k is the constant of proportion

To find k use the condition when q = 1, p = 1

1 = k(1 + 2)² = k × 3² = 9k ( divide both sides by 9 )

\(\frac{1}{9}\) = k

p = \(\frac{1}{9}\) (q + 2)² ← equation of proportion

When q = 10 , then

p = \(\frac{1}{9}\) × (10 + 2)² = \(\frac{1}{9}\) × 12² = \(\frac{1}{9}\) × 144 = 16

If the distance to a star was suddenly cut in half, it would appear four times brighter.

The brightness of a star is directly proportional to the inverse square of its distance from us. This means that if the distance to a star is halved, its brightness will increase by a factor of four.

The relationship between brightness and distance can be expressed as follows:

B = k / d^2

where B is the brightness, k is a constant of proportionality, and d is the distance.

If the distance to the star is halved, it can be expressed as:

d' = d / 2

Plugging this into the equation for brightness, we get:

B' = k / (d / 2)^2

Expanding this and simplifying, we get:

B' = 4 * k / d^2

Since k is a constant, it cancels out and we are left with:

B' = 4 * B

This means that if the distance to a star was suddenly cut in half, it would appear four times brighter. In astronomical terms, this is equivalent to an increase of 2 magnitudes on the logarithmic magnitude scale.

During the second minute of a two-minute training session, a rock climber completed a 12-meter ascent up the wall. The climber returned to the identical location she had been in at the beginning of the two-minute session.

Let x be the distance climbed by the climber is x m

During the first minutes(60 seconds): distance climbed =\(\frac{x}{60}\)

In the 2nd minute, they climbed 12 m higher than in the 1st minute.

Now, the distance climbed by the climbed in the Second minute = \(\frac{x+12}{60}\)

Now, the change in the elevation during the first minute of the training session= \(\frac{x+12}{60}-\frac{x}{60} = \frac{12}{60}=\frac{2}{10}=\frac{1}{5}\)
