The surface area of the cone is 450π in². Therefore, the answer is option B.

The surface area of a cone can be represented as follows:

surface area of a cone = πr(r + l)

where

Therefore,

r = 9 inches

l = 41 inches

Hence,

surface area of a cone = π × 9(9 + 41)

surface area of a cone = 9π(50)

Therefore,

surface area of a cone = 450π inches²

In order to find equation, first find slope:

\(\sf slope : \dfrac{y_2 - y_1}{x_2 - x_1} \quad where \ (x_1, y_1) , \ (x_2, y_2) \ are \ points\)

Given points: (-3, 7) and (6, -5)

\(\rightarrow \sf slope : \dfrac{-5-7}{6-(-3)} =-\dfrac{4}{3}\)

Equation:

\(\sf y- y_1 = m(x - x_1)\)

insert values

\(\rightarrow \sf y - 7 = -\dfrac{4}{3} (x -(-3))\)

Step-by-step explanation:

The probability that George used a personal check is 48% since 48% of shoppers used both credit cards and checks.

The shopping mall has determined that 60% of the shoppers used credit cards to pay for their purchases, and 48% of the shoppers used both credit cards and personal checks to pay for their purchases. This means that 12% of the shoppers used only personal checks to pay for their purchases.

Since George is found to have used a credit card for at least one purchase on that day, it means that he may have used a personal check as well. Therefore, the probability that he used a personal check is 48%, since 48% of shoppers used both credit cards and checks. This is based on the assumption that there are no other payment methods used by the shoppers.

The circumstance that the score is located 5 points above the mean a central value, relatively close to the mean is when the population standard deviation is much greater than 5.

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Here, we have

We have to find under what circumstances is a score that is 5 points above the mean considered a central value--meaning it is relatively close to the mean.

We concluded from the above statement that when the population standard deviation is much greater than 5.

Hence, when the population standard deviation is much greater than 5 then, the score that is 5 points above the mean is considered a central value.

Therefore, the correct option is D.

Step-by-step explanation:

Find the length side of the smaller square

The area of the square is equal to

A = a^2

so

a^2 = 13

a = √13 units

step 2

Find the length side of the larger square

The area of the square is equal to

A = b^2

so

b^2 = 29.25

b = √29.25 units

step 3

Find the value of x

Applying the Pythagoras Theorem

x^2 = a^2 + b^2

x^2 = 13 + 29.25

x^2 = 42.25 units

x = √42.25

x = 6.5 units

The area of the square adjacent to the third side of the triangle is 85 square units.

Important information:

According to the Pythagoras theorem:

\(a^2=b^2+c^2\)

Where, a is hypotenuse and b, c are two legs of a right-angle triangle.

Area of a square is the square of side length. So, \(b^2=35\) and \(c^2=50\). Now,

\(a^2=35+50\)

\(a^2=85\)

Therefore, the area of the square adjacent to the third side of the triangle is 85 square units.

Therefore, the value of n that makes the system of equations true is n = 10.

Given:

p = 2n

p - 5 = 1.5n

Substituting the value of p from the first equation into the second equation, we have:

2n - 5 = 1.5n

Next, we can solve for n by subtracting 1.5n from both sides of the equation:

2n - 1.5n - 5 = 0.5n - 5

Simplifying further:

0.5n - 5 = 0

Adding 5 to both sides of the equation:

0.5n = 5

Dividing both sides by 0.5:

n = 10

Therefore, the value of n that makes the system of equations true is n = 10.

In response to the stated question, we can state that here  Hence, the linear equation (6 2 • 35) 2 equals 1/4096

A linear equation is one that satisfies the algebraic formula y=mx+b. m is the y-intercept, while B is the slope. The foregoing sentence is sometimes referred to as a "linear equation with two variables" because y and x are variables. Bivariate linear equations are two-variable linear equations. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. An equation is said to be linear if its formula is y=mx+b, where m denotes the slope and b the y-intercept. It is referred to as being linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.

We must do the following operations in the correct order to simplify the formula (62 • 35)2:

To start, we must multiply 2 by 35, which results in the number 70.

The result is -64 when we remove 70 from 6.

The final step is to raise the unfavorable integer -64 to the power of -2.

Hence, we can write:

\((6-2 * 35)-2 = (-64)^{-2}\)

To make this statement easier to understand, keep in mind that taking the reciprocal of a number raised to a positive power is the same as raising it to a negative power. With those words:

\(a^-n = 1/a^n\\(-64)^-2 = 1/(-64)^2\\1/(-64)^2 = 1/4096\)

Hence, the expression (6 2 • 35) 2 equals 1/4096.

Step-by-step explanation:

Answer:

9/11

Step-by-step explanation:

Answer:

30°, 60° and 90°

Step-by-step explanation:

Given the expression Arccos (√3/2)=β, we can use the expression to calculate one of the acute angles in a right angled triangle.

Note that a right angled triangle is made up of two acute angles and a right angled (90°)

Let's get one of the acute angles first

If Arccos (√3/2)=β

β = cos^-1 √3/2

β = 30°

This shows that one of the acute angles is 30°

To get the third angle, we know that sum of angles in a triangle is 180° and since we already know two of the angles, i.e 90° and 30°, we can get the third angle.

90+30+x = 180

120+x = 180

x = 180-120

x = 60°

All the angle measurement for the right angled triangle are 30°, 60° and 90°

The velocity of the truck after the collision would be 24 m/s east.

The law of conservation of momentum states that the momentum of a closed system remains constant if no external forces act on it. In this case, we can assume that the car and the truck form a closed system.

The momentum of an object is given by its mass multiplied by its velocity, p = mv. Initially, the momentum of the system is:

p_initial = m_car * v_car + m_truck * v_truck

where m_car and v_car are the mass and velocity of the car, and m_truck and v_truck are the mass and velocity of the truck.

After the collision, the car is stopped, so its velocity is 0. The momentum of the system after the collision is:

p_final = m_car * 0 + m_truck * v'_truck

where v'_truck is the velocity of the truck after the collision.

Since momentum is conserved, we can set p_initial equal to p_final:

m_car * v_car + m_truck * v_truck = m_truck * v'_truck

Solving for v'_truck, we get:

v'_truck = (m_car * v_car + m_truck * v_truck) / m_truck

Substituting the given values, we have:

v'_truck = (1200 kg * 40 m/s + 2000 kg * 0 m/s) / 2000 kg

v'_truck = 24 m/s east

Therefore, the velocity of the truck after the collision would be 24 m/s east.

Let x be the number of small boxes and y be the number of large boxes.

The contractor bought a total of 13 boxes that have 3350 nails altogether.

x + y = 13                     ...............(1)

50x + 350y = 3350              ..........(2)

From equation (1),

x = 13 - y             ...........(3)

Substitute x = 13- y in equation (2)

50(13 - y) + 350y = 3350
