What is the surface area of this right triangular prism?

Enter your answer in the box.

Answer:

2x + [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

The like terms that you want to combine is 1/3 and 1/2.  You need a common denominator which would be 6

[tex]\frac{1}{3}[/tex] = [tex]\frac{2}{6}[/tex]

[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{6}[/tex]

2x + [tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex]

2x + [tex]\frac{5}{6}[/tex]  You cannot combine this with the 2 because the 2 is multiplied by x.

Answer: 36

Step-by-step explanation:

After 5 half-lives, only 3.9 g of the original 155 g of radioactive isotope will remain.

Number is a mathematical object used to count, measure, and label. It is an abstract concept that can be represented in a variety of forms, such as the natural numbers, real numbers, and complex numbers. Numbers can be used to describe physical quantities, such as volume, mass, and time, as well as abstract quantities, such as sets, functions, and abstract objects. Numbers are also used to represent concepts such as truth, beauty, and goodness.

To calculate this, we can use the formula:
Final Mass = Initial Mass * (1/2)Number of Half Lives

In this case, the Initial Mass is 155 g, and the Number of Half Lives is 5. Therefore, the equation to use is:
Final Mass = 155 g * (1/2)⁵

Plugging the numbers into the equation, we get:
Final Mass = 155 g * (1/2)⁵
Final Mass = 155 g * (1/32)
Final Mass = 3.9 g

Therefore, after 5 half-lives, only 3.9 g of the original 155 g of radioactive isotope will remain. This is due to the fact that the half-life of a radioactive isotope is the amount of time it takes for the isotope to be reduced to half its original mass. As the number of half-lives increases, the amount of the isotope left decreases exponentially.

The standard form equation of a circle whose diameter endpoints are  (-3,4) (2,1) is [tex](x - (-0.5))^2 + (y - 2.5)^2[/tex] = 6.5

The general form of the equation of a circle is (x - h)² + (y - k)² = r², where (h, k) represents the center of the circle and r represents the radius. This equation is derived using the Pythagorean theorem, which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. By setting (x - h)² and (y - k)² equal to r² and then combining the two equations, we get the standard form equation of a circle.

The center of the circle lies in the middle of the diameter, so we find the midpoint of the end points:

[tex](\frac{-3+2}{2} , \frac{4+1}{2} )[/tex] = (-0.5, 2.5)

And radius of the circle is half of the diameter, which is:

[tex]\frac{\sqrt{( 2-(-3))^2 + (1-4)^2 )}}{2}[/tex] = [tex]\frac{\sqrt{26}}{2}[/tex]

Therefore, the circle equation is:

[tex](x - (-0.5))^2 + (y - 2.5)^2[/tex] = [tex](\frac{\sqrt{26} }{2} )^2[/tex] = 26/4 = 6.5

The cost of a liter of milk is $2.50 and the cost of a loaf of bread is $2.50.

Cost is the value of goods or services measured in money or other forms of exchange. It is the amount that must be given up in exchange for something else. Costs are typically incurred in the production of goods and services, and can include both tangible and intangible elements, such as labor, materials, overhead, and financing.

The total cost for 3 liters of milk and 5 loaves of bread was $11. Therefore, the cost for 1 liter of milk was ($11 / 3) = $3.67. The cost for 1 loaf of bread was ($11 / 5)
= $2.20.
The total cost for 4 liters of milk and 4 loaves of bread was $10. Therefore, the cost for 1 liter of milk was ($10 / 4) = $2.50. The cost for 1 loaf of bread was ($10 / 4)

The length of XY uisng the midpoint theorem is 40 units

The midpoint theorem states that if a line segment is drawn connecting the midpoints of two sides of a triangle, then that line segment is parallel to the third side of the triangle, and its length is half the length of the third side.

In this case, we have a triangle XYZ, and points A, B, C are the midpoints of sides XY, YZ, and ZX respectively.

By the midpoint theorem, we know that AB is parallel to ZX and has a length of half of ZX.

Similarly, BC is parallel to XY and has a length of half of XY, and AC is parallel to YZ and has a length of half of YZ.

We are given that BC has a length of 20, and we want to find the length of XY.

Using the midpoint theorem, we know that

XY is twice the length of BC

So

XY = 2 * BC = 2 * 20 = 40.

There are 250 students in the sixth grade.

First, let's define some variables:

The total number of sixth-grade students is called "x."

The number of students who purchased their lunches will be referred to as "p."

The number of students who brought their lunch from home will be referred to as "h."

We know that from the problem statement that

p + h = x (since all students either purchased their lunch or brought their lunch from home)

p = 0.24x (since 24% of the students purchased their lunch)

h = 190 (since 190 students brought their lunch from home)

We can use these equations to solve for x:

p + h = x

0.24x + 190 = x (substituting in the value of p and h from the other equations)

0.76x = 190 (subtracting 0.24x from both sides)

x = 250 (dividing both sides by 0.76)

Step-by-step explanation:

The function f(x) = 4(1+0.1/0.5)^0.5x can be simplified using the order of operations, which is PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction).

First, we can simplify 0.1/0.5 to get 0.2.

Next, we can simplify (1 + 0.2) to get 1.2.

Then, we can simplify (1.2)^0.5 to get approximately 1.095.

Finally, we can multiply 4 by 1.095^x to get the simplified function:

The missing data value in the project is 25.5.

Range is a statistical measure that represents the difference between the highest and lowest values in a dataset. It is calculated by subtracting the smallest value in the dataset from the largest value.

To find the missing data value, we need to use the given range and the known data values.

The range is the difference between the highest and lowest values in the data set. So, if we sort the given data values in increasing order, we have:

11, 15, 15, 22, 29, 31

The range is 33, which means that:

highest value - lowest value = 33

31 - 11 = 33

So, the missing data value must be between 22 and 29 (since those are the values that are next to each other in the sorted list). To find the exact value, we can take the average of 22 and 29:

(22 + 29) / 2 = 25.5

Therefore, the system of equations that could be used to determine the number of liters of Drink A made and the number of liters of Drink B made is.

[tex]0.1x + 0.2y = 70[/tex]

[tex]y = 3x[/tex]

Where x represents the number of liters of Drink B made, and y represents the number of liters of Drink A made.

Let's define the variables as follows:

Let x be the number of liters of Drink B produced.

Since the company produced 3 times as many liters of Drink A as liters of Drink B, let y be the number of liters of Drink A produced, so y = 3x.

Now, let's write the system of equations:

The total amount of real fruit juice used is 70 liters, so we can write:

[tex]0.1x + 0.2y = 70[/tex]

Substituting y = 3x into the above equation, we get:

[tex]0.1x + 0.2(3x) = 70[/tex]

Simplifying the equation:

[tex]0.1x + 0.6x = 70[/tex]

[tex]0.7x = 70[/tex]

As a result, the vertex form of the f(x) equation is: [tex]f(x) = -(x - 5)^2 + 2[/tex]which is equivalent to choice (b).

A quadratic function is a sort of second-degree polynomial equation, meaning it has at least two squared element. A quadratic equation's generic form is: [tex]ax^2 + bx + c = 0[/tex] where the variable x and the constants a, b, and c. If the coefficient a were zero, the expression would be linear rather than quadratic. Several ways to solve a quadratic equation, including factoring, squaring the square, and utilising the quadratic formula. The negative numbers or roots of the quadratic equation are the values of x which it make the equation true and are the solutions to the quadratic equation.

given

The factored form of the quadratic function f(x), which has roots of 3 and 7, is as follows:

f(x) = a(x - 3)(x - 7) (x - 7) where "a" stands for a fixed coefficient.

We can utilise the point (1, 12) through which the function passes to determine the value of "a"

12 = a(1 - 3) (1 - 3)(1 - 7)

12 = -24a

a = -1/2

Inputting the value of "a" into the factored form yields the following results:

[tex]f(x) = -1/2(x - 3)(x - 7) (x - 7)[/tex]

By extending this phrase, we get:

[tex]f(x) = -1/2(x^2 - 10x + 21)[/tex]

We need to finish the square before we can transform this into vertex form. To achieve this, add and remove the square of the coefficient of x's half:

[tex]f(x) = -1/2(x^2 - 10x + 25 - 4)[/tex]

If we condense this phrase, we get:

[tex]f(x) = -1/2[(x - 5)^2 - 4][/tex]

Answer:

d. x > 2 or x < -2

Step-by-step explanation:

Domain describes the range of x-values in a function.

Domain

The domain of a graph is all of the x-values covered by the function. The domain does not reflect the y-values of a function. This means that answers A and B are automatically wrong.

By looking at the graph, we can tell that there is a gap where some x-values are not covered. This gap is known as a discontinuity. The discontinuity begins at -2 and ends at 2. All of the x-values in the discontinuity are not a part of the domain, and any parts of the graph that are continuous, are included in the domain. The graph is continuous at all points greater than 2 and less than -2, so all of those values are included in the domain. Now, we just need to find out if the endpoints are included in the domain.

Included Values

We know that the domain includes all x-values greater than 2 and less than -2, but we need to know if the domain includes 2 and -2. On a graph, included values will be shown as a closed circle and non-included values will be shown as an open circle. By looking at the graph, we can tell that 2 is not included but -2 is. This means that the domain is x > 2 or x < -2 because the domain does not include x = 2.
