The length of the other diagonal is 22.36 cm.

Diagonal is defined as a sloping line or the slant line, that connects to the vertices of a shape.

Let's call the length of the other diagonal "d".

Since a rhombus has perpendicular diagonals that bisect each other

we can use the Pythagorean theorem to find the length of the other diagonal:

d^2 = 10^2 + 10^2 = 100

d = sqrt(100) = 10 * sqrt(10) = 10 * 2.236 = 22.36 cm

Therefore, the length of the other diagonal is 22.36 cm.

Answer:

8 bags of chips.

Step-by-step explanation:

First, find the cost per individual unit. It is given that 2 bags of chips cost $6. Find the cost of one bag by dividing 6 with 2:

$6/2 bags = $3/bag

Next, you are solving for the amount of chips you can buy with $24. Divide 24 with the individual cost of $3:

$24/$3 per bag = 8

You can buy 8 bags of chips assuming all things are the same.

The values of t and s that satisfy the equality are t = sqrt(3 * 74.67 / 49) and s = sqrt(3 * 74.67 / 49).

The equality ⟨−(7t^2), 3s-2t⟩ = ⟨3s-t,24t⟩ means that the two vectors are equal, so the components must be equal:

-7t^2 = 3s-t

3s-2t = 24t

Solving for t, we can subtract 24t from both sides:

3s-26t = 0

Dividing both sides by 3, we get:

s - 8.67t = 0

So, t = s / 8.67.

Substituting t = s / 8.67 back into the first equation, we get:

-7(s / 8.67)^2 = 3s - s / 8.67

Expanding and simplifying, we get:

-49s^2 / 74.67 + 3s = s^2 / 74.67

Dividing both sides by s^2 / 74.67, we get:

-49 + 3 * 74.67 / s = 1

Multiplying both sides by s^2 / 74.67, we get:

-49s^2 + 3 * 74.67 = s^2

Expanding and rearranging, we get:

s^2 - 49s^2 + 3 * 74.67 = 0

Combining like terms, we get: -49s^2 + 3 * 74.67 = 0

Dividing both sides by -49, we get: s^2 = 3 * 74.67 / 49

Taking the square root of both sides, we get: s = sqrt(3 * 74.67 / 49)

Thus, the values of t and s that satisfy the equality are t = sqrt(3 * 74.67 / 49) and s = sqrt(3 * 74.67 / 49).

The student's lifetime value for a four-year degree at this college is $80,000.

The student's lifetime value for a four-year degree can be calculated as follows:

Determine the cost per semester: $10,000 per semester

Determine the number of semesters for a four-year degree: 4 years * 2 semesters/year = 8 semesters

Multiply the cost per semester by the number of semesters to get the total cost of tuition: $10,000 * 8 = $80,000

Therefore, the student's lifetime value for a four-year degree at this college is $80,000.

The term "domain" refers to a group of potential input values, and the domain of a graph is made up of all the input values visible on the x-axis.

All the y values from the ordered pairings are listed to determine the range. Values that are repeated inside the domain or range don't need to be listed more than once. Each x must have a unique y value in order for a relation to be a function.

Simply solving for y = f(x) yields the values of the independent variable x and the domain, which we can use to determine the domain and range. Simply write x as x=g(y) to determine the function's range, and then identify g's domain.

Utilizing graphs is another method for determining the domain and range of functions. The collection of possible input values is referred to as the domain, and the domain of a graph is made up of all the input values displayed on the x-axis.

The length of the crust around the larger pizza is equal to: B. 51.81 inches.

Mathematically, the circumference of a circle can be calculated by using this mathematical expression:

C = 2πr or C = πD

Where:

For Restaurant 1: One large 16-inch pizza is sold for $14.99.

1 inch = 2.54 centimeters

16 inches = 16 × 2.54 = 40.64 centimeters

Therefore, restaurant 1 sells one large 40.64 cm pizza for $14.99.

For Restaurant 2: One large 41.91-centimeter pizza is sold for $14.99

Since we know that 41.91 centimeters is greater than 40.64 centimeters, restaurant 2 offers the larger pizza.

Now, we can calculate the length of the crust around the pizza, which is the same as the circumference of the pizza (circle)

C = π × d

C = 3.14 × 41.91

C= 131.5974 centimeters

Answer: 20 ft

Step-by-step explanation:
We can imagine the ladder, wall and ground as a triangle.
(And because we don't know if our triangle has a 90 degrees angle it means it's an ordinary triangle.)

We know that a triangle that has an angle with 60 degrees means all of its angles have 60 degrees because 180 : 3 angles = 60 degrees which means the triangle is equilateral.

Definition of the equilateral triangle: The triangle that has the 3 side with the exact same length.


From the equilateral triangle we know all sides are equal. If the ladder is 20 ft that means the distance between the building and the base of the ladder (which is actually the base of our triangle) is 20 ft.

Earth removed from a building site is 357 cubic yards.

A contractor's truck can haul 17 cubic yards per load.

To find how many truckloads were needed, we needed to divide the earth removed from the building site by the contractor's truck capable of hauling.

That is,  

The number of truckloads = earth removed from the building site/contractors' truck capable of hauling.

The number of truckloads = 357 cubic yards/17 cubic yards per load

The number of truckloads = 21 truckloads.

Any qualities, quantity, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable. Examples of variables include age, sex, company income and expenses, country of birth, capital expenditures, class grades, eye color, and vehicle kind.

The joint p.d.f of X and Y is f(x, y)

f(x,y) = cxy/ 1+[tex]x^{2}[/tex]+[tex]y^{2}[/tex] for 0 < x < 1 and 0 < y < 1

Lower limit: y = 0⇒t=1+[tex]x^{2}[/tex]

A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations. This mathematical operation enables the multiplication, division, addition, or subtraction of numbers. The following is the structure of an expression: Expression: (Number/Variable, Math Operator, Math Operator)

We know that:

Total number of cherries = 780

Number of cherries on the plate = 145

Number of cherries in the bowl = 4 * (Number of cherries in the cup + Number of cherries on the plate)

So we can set up the equation:

x + 145 + 4(x + 145) = 780

Simplifying, we can combine like terms:

x + 145 + 4x + 580 = 780

5x + 725 = 780

Subtracting 725 from both sides:

5x = 55

Finally, we can divide both sides by 5:

The fountain should be located at the coordinates (4,2). This is the midpoint of the line segment that connects the vertices a(-1,-1) and c(7,-1). It is also the same distance from b(4,4).

To find the location of the fountain, we first need to find the midpoint of the line segment connecting the vertices a(-1,-1) and c(7,-1). This midpoint is located at the coordinates (4,2). To verify that this is the correct location, we can calculate the distance between the midpoint and each vertex. To do this, we use the distance formula, which is d=√((x2-x1)2+(y2-y1)2). Using the coordinates for the midpoint (4,2) and the coordinates for vertex a(-1,-1), we get d=√((42-(-12))2+((22-(-12))2). This simplifies to d=√((52+52))=√(50)=7.07. We can repeat the same process for the midpoint and vertex b(4,4) and for the midpoint and vertex c(7,-1). In both cases, we find that the distance is 7.07, so the fountain should be built at the coordinates (4,2).
