Answer:

14.5

Step-by-step explanation:

According to Euclidean relation the product of height and base multiplied is equal to the product of legs multiplied:

x × 29 = 21 × 20

29x = 420

x = 14.5 approximately.

Answer:

PLEASE MARK AS BRAINLIEST

Step-by-step explanation:

5 x 4.5 = 22.5 (km)

150 – 22.5 = 127.5 (km)

35 – 5 = 30 (km/h)

127.5/30 = 4.25 (h)

4.25 x 35 = 148.75 (km)

Alternatively,

Let x be the distance that he cycles.

x/35 + (150 – x)/5 = 4.5

x + 1050 – 7x = 157.5

6x = 892.5

x = 148.75

Ans : 148.75km.

Step 3 is unnecessary (the statement is already given, plus you haven't proven the triangle is isosceles anyway).

After, omit step 5 and jump straight to 6.

After this, step 6 is the statement that used to be step 5, which is true by CPCTC.

Then, you can prove the required statement by definition from this.

The total volume of the ice cream is -4.76 cubic inches.

The volume of the frustum of a cone can be calculated as follows:

V = (1/3) × π × h × (r1² + r2² + r1 × r2), where r1 and r2 are the radii of the top and bottom base of the cone.

And the volume of a sphere can be calculated as follows:

V = (4/3) × π × r³, where r is the radius of the sphere.

To calculate the total volume of the ice cream, we need to subtract the volume of the cone from the volume of the sphere.

Let's first calculate the radii of the top and bottom base of the cone.

r1 = (di/2) = (1.25/2) = 0.625 in.

r2 = (d0/2) = (2.25/2) = 1.125 in.

Now, we can estimate the volume of the cone.

V_cone = (1/3) × π × h × (r1² + r2² + r1 × r2)

= (1/3) × π × 2 × (0.625² + 1.125² + 0.625 × 1.125)

= 6.45 cubic inches.

Next, let's calculate the radius of the sphere.

r_sphere = (di/2) = (1.25/2) = 0.625 in.

And finally, we can calculate the volume of the sphere.

V_sphere = (4/3) × π × 0.625³

= 1.69 cubic inches.

So, the total volume of the ice cream is given by:

V_ice_cream = V_sphere - V_cone

= 1.69 - 6.45

= -4.76 cubic inches.

Note: Since the volume of the cone is larger than the volume of the sphere, the total volume of the ice cream will be negative, indicating that it is not possible to fill a frustum of a cone with ice cream in the manner described.

Given:

The distance between the two points (11, 1) and (x, 17) is 20.

To find:

The possible values of x.

Solution:

Distance formula is:

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Using this formula, the distance between (11, 1) and (x, 17) is

\(D=\sqrt{(x-11)^2+(17-1)^2}\)

\(20=\sqrt{x^2-22x+121+(16)^2}\)

\(20=\sqrt{x^2-22x+121+256}\)

Taking square on both sides.

\(400=x^2-22x+377\)

\(0=x^2-22x+377-400\)

\(x^2-22x-23=0\)

Splitting the middle term, we get

\(x^2-23x+x-23=0\)

\(x(x-23)+(x-23)=0\)

\((x-23)(x+1)=0\)

Using zero product property, we get

\(x=-1,23\)

Therefore, the possible values of x are -1 and 23.

The perimeter of the regular octagon with an apothem of 5 units will be 33.14 units.

Since, We know that;

All the sides of the regular polygon are congruent to each other. The perimeter of the regular polygon of n sides will be the product of the number of the side and the side length of the regular polygon.

P = (Side length) x n

Here, The Apothem of a regular octagon is 5 units.

Then the side length of the regular octagon is given as,

tan (360° / (2 × 8)) = (n/2) ÷ 5

tan 22.5° = n / 10

n = 4.142

Then, the perimeter is given as,

P = 8 x 4.142

P = 33.14 units

Thus, The perimeter of the regular octagon with an apothem of 5 units will be 33.14 units.

Step-by-step explanation:

x = number of sold sodas

y = number of sold hot dogs

x + y = 124

x = 3y

so,

3y + y = 124

4y = 124

y = 31

x = 3y = 3×31 = 93

there were 93 sodas and 31 hot dogs sold.

This is true because a probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.

The area under the probability distribution is a measure of the probability of all the possible outcomes. Since the sum of all the probabilities of all the possible outcomes must be 1, the total area under the probability distribution must also be 1. This is because the probability of an event happening is the area under the curve of the probability distribution at that event. Thus, the total area under the probability distribution must always equal 1.

Binomial Distribution:

The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a series of n independent experiments. Each asks a yes-no question and each has its own Boolean outcome: success (probability p) or failure (probability p) (probability q = 1-p.  A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a series of results is called a Bernoulli process. For one trial, n = 1, binomial distribution is Bernoulli distribution. The binomial distribution is the basis for the common binomial test of statistical significance.

In general, (A + B)⁵ = A⁵ + 5A⁴ᵇ + 10A²ᵇ*³ + 10A³ᵇ*² + 5AB⁴ + B⁵

So,

Multiplying that by (1 + ax) gives:

3^5 + 5*3^4*(-2x) + 10* 3^3 *(-2x)^2 + 10*3^2*(-2x)^3 + 5*3*(-2x)^4 + (-2x)^5 + ax(3^5 + 5*3^4*(-2x) + 10* 3^3 *(-2x)^2 + 10*3^2*(-2x)^3 + 5*3*(-2x)^4 + (-2x)^5).

In bold, we find the terms of x^2, so the coefficient of x^2 is 10*3^3*(-2)^2+a*5*3^4*(-2) = 360 - 810a

2x³y⁶

Step-by-step explanation:

A rectangle is a plan shape with pair of opposite side equal and parallel.

The Area of a rectangle is

A =  L×W ........................... Equation 1

Where L = Length, W = Width.

make W the subject of the equation.

W = A/L.................... Equation 2

Given: A = 28x⁶y⁹ square feet, L = 14x³y³ feet.

Substitute into equation 2

W = 28x⁶y⁹/14x³y³

W = 2x³y⁶ feet.

Hence the expreesion for the width is 2x³y⁶

Answer:

W = 2*x^3*y^6

Step-by-step explanation:

For this problem, we need to use the relationship:

a^x/a^y = a^(x - y)

For a rectangle with length L and width W, the area is:

A = L*W

We know that in this case we have:

A = 28*x^6*y^9

and:

L = 14*x^3*y^3

We want to find the value of W.

Using the above equation, we have that:

A = 28*x^6*y^9 = L*W = (14*x^3*y^3)*W

28*x^6*y^9 = (14*x^3*y^3)*W

We can solve this for W by isolating it in the right side.

First, let's divide by 14 in both sides to get:

(28*x^6*y^9)/14 = (14*x^3*y^3)*W/14

(28/14)*x^6*y^9 = (14/14)*x^3*y^3*W

2*x^6*y^9 = x^3*y^3*W

Now let's divide by x^3 in both sides to get:

(2*x^6*y^9)/x^3 = (x^3*y^3*W)/x^3

2*(x^6/x^3)*y^9 = (x^3/x^3)*y^3*W

Now we use the relationship that is in the beginning:

2*x^(6 - 3)*y^9 = y^3*W

2*x^3*y^9 = y^3*W

Now let's divide by y^3 in both sides:

(2*x^3*y^9)/y^3 = (y^3*W)/y^3

2*x^3(y^9/y^3) = (y^3/y^3)*W

2*x^3*y^(9 - 3) = W

2*x^3*y^6 = W

The width of the rectangle is given by the equation:

W = 2*x^3*y^6

The inequality that can be used to determine cc, the greatest number of 110-kilogram crates that can be loaded onto the shipping container is 3800 + 110cc = 23000.

It should be noted that from the information, the greatest weight that can be loaded into the container is 23000 kilograms and other shipments weighing 3800 kilograms have already been loaded into the container.

Therefore, the greatest number of 110-kilogram crates that can be loaded onto the shipping container will be:

3800 + 110cc = 23000

It should be noted that cc represents the number that can be loaded.

Step-by-step explanation:

Another possible vertex of the square is determined as (2, 1).

option B is the correct answer.

The vertex of a figure is the point of intersection of two sides of the shape.

The perimeter of the square is given as 12 units, the length of each side of the square is calculated as follows;

P = 12 units

a side length = 12 units / 4 = 3 units

To determine another possible vertex of the square, the length between the points must be equal to 3.

Let's consider point A;

A = (1, 2)

given vertex = (-1, 1)

distance between the points = √ (-1 -1)² + (1 - 2)² = √5

Let's consider point B;

B = (2, 1)

given vertex = (-1, 1)

distance between the points = √ (-1 -2)² + (1 - 1)² = √9 = 3

Thus, point B is another possible vertex of the square.
