Answer:
A regular prism with 10 faces and 12 vertices has 6 sides. This is because the number of faces and vertices are related by the equation F+2 = E+2V, where F is the number of faces, E is the number of edges, and V is the number of vertices. In this case, 10+2 = 12+2V, so V = 6 and the number of sides of the prism is also 6
Step-by-step explanation:
1. A regular prism has 10 faces and 12 vertices.
2. The number of faces and vertices is related by the equation F+2 = E+2V.
3. Where F is the number of faces, E is the number of edges, and V is the number of vertices.
4. In this case, 10+2 = 12+2V, so V = 6.
5. Therefore, the number of sides of the prism is also 6.

find an equation in the form y=mx+b, where x is the number of monthly minutes and y is the total monthly of the splint plan.
B) Use your equation to find the total monthly cost if 866 minutes are used.
Answer: If 866 minutes are used, the total cost will be dollars.
Therefore , the solution of the given problem of equation comes out to be total cost for 866 minutes is $1487.
What is an equation?The similar symbol (=) is used in arithmetic equations to signify equality between two statements. It is shown that it is possible to compare various numerical factors by applying mathematical algorithms, which have served as expressions of reality. For instance, the equal sign divides the number 12 or even the solution y + 6 = 12 into two separate variables many characters are on either side of this symbol can be calculated. Conflicting meanings for symbols are quite prevalent.
Here,
Given :
customer uses 390 minutes , the monthly cost will be $178.
customer uses 940 minutes, the monthly cost will be $398.
To find an equation ,
where x is number of monthly minutes
and y is total monthly of splint plan.
So , equation is :
=> y =mx +b
For first case :
=> 178 = 390x + b
Second case :
=> 398 = 940x + b
Solve for x:
=> 178 - 390x = 398 - 940x
=> -200x = - 550
=> x = 550/200
=>x = 55/20
=>x = 11/4
=> x = 2.75
For value of b
=> 178 = 390(2.75) + b
=> 178 - 1072.5 = b
=> -894.5 = b
B)
=> y = 866(2.75) - 894.5
=> y = 2381.5 - 894.5
=> y = 1487
Therefore , the solution of the given problem of equation comes out to be total cost for 866 minutes is $1487.

The number of phones and accessories sold are 8 and 24 respectively.
How to find the number of phone and accessories sold?Indigo works as a salesperson at an electronics store and sells phones and phone accessories. Indigo earns a $8 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Indigo made a total of $160 in commission from all accessory and phone sales and she sold 3 times as many accessories as phones.
Therefore, the number of phones and accessories she sold can be calculated as follows:
Using equation,
let
x = number of phone sold
y = number of accessories sold.
Therefore,
8x + 4y = 160
y = 3x
Therefore,
8x + 4(3x) = 160
8x + 12x = 160
20x = 160
x = 160 / 20
x = 8

A truck with 0.300 m radius tires travels at 28.0 m/s.
a) What is the angular velocity of the rotating tires in radians per second?
b) What is this in revolutions per minute?
Answer:
Angular velocity = 93.33 radians/second
Revolutions per minute = 1,782.51 revolutions per minute
Step-by-step explanation:
The relation between angular velocity, ω and linear velocity, v is given by the equation
[tex]\omega = \dfrac{v}{r}[/tex]
where ω is in radians per second
v = m/s
and r is the radius (m) of the circular motion, in this case, the radius of the tire
Given v = 28 m/s and r = 0.300 m
we get
[tex]\omega = \dfrac{28 \;m/s}{0.3\;m} = 93.33 \;radians/second[/tex]
Since 2π radians make a full revolution, 93.33 radians/sec = 93.33 ÷ 2π = 29.708 revolutions per second
To get the revolutions per minute, multiply this by 60 since there are 60 seconds to a minute:
29.708 x 60 = 1,782.51 revolutions per minute
demonstrating that there is a trade which will leave both players better
off. Suppose:
Amber can produce 24 apples or 48 pears in a day, and
Johnny can produce 8 apples and 32 pears in a day.

This trade will create a win-win situation for both players, leaving them both better off than they were before.
What is capacity?Capacity in math is the maximum amount that a container or figure can hold. It is typically measured in liters, gallons, or quarts and is determined by the size of the container or figure. Capacity is a measure of volume and is used in a variety of math problems, including those involving capacity conversion, calculating the amount of liquid that can be stored in a container, and determining the amount of material needed to fill a given area.
A trade that will leave both players better off is for Amber to produce all of the apples and Johnny to produce all of the pears. This way, Amber can produce 24 apples in a day and Johnny can produce 32 pears in a day, which is more efficient than if they both tried to produce both items. Amber has a higher capacity for producing apples while Johnny has a higher capacity for producing pears. Therefore, this trade makes the most sense.
The trade will leave both players better off because of the increased efficiency in production. Amber can produce 24 apples in a day and Johnny can produce 32 pears in a day, which is more efficient than if they both tried to produce both items. This means that they will both have more resources to spend on other things. They will also be able to divide their time more evenly between the two tasks, allowing them to be more productive and efficient.
In addition, the trade will also benefit both players in terms of their preferences. Amber will be able to spend a full day producing apples, which she prefers, and Johnny will be able to spend a full day producing pears, which he prefers. This trade will create a win-win situation for both players, leaving them both better off than they were before.

3) Destiny has 800 gallons of water in her pool and is adding water at a rate of 25 gallons per minute. Jabez only has 20 gallons of water in his pool but water is being added at a rate of 45 gallons per minute. How long before both pools have the same amount of water? answer fast pls
Answer: After 39 minutes, both pools will have the same amount of water.
Step-by-step explanation:
Let's call the number of minutes elapsed t. Then the amount of water in Destiny's pool after t minutes is 800 + 25t gallons, and the amount of water in Jabez's pool after t minutes is 20 + 45t gallons.
We want to find the time t at which the two pools have the same amount of water, so we set their amounts equal:
800 + 25t = 20 + 45t
Subtracting 20 from both sides of the equation:
780 + 25t = 45t
Subtracting 25t from both sides of the equation:
780 = 20t
Dividing both sides of the equation by 20:
39 = t
So, after 39 minutes, both pools will have the same amount of water.

$540 is invested in an account earning 9.1% interest (APR), compounded
continuously. Write a function showing the value of the account after t years, where
the annual growth rate can be found from a constant in the function. Round all
coefficients in the function to four decimal places. Also, determine the percentage of
growth per year (APY), to the nearest hundredth of a percent.
Answer: The formula for continuously compounded interest is given by:
A = P * e^(rt)
Where:
A = the final account balance
P = the initial investment (principal)
r = the annual growth rate as a decimal
t = the number of years the investment is held
In this case, P = 540, r = 0.091 and t = t years.
So, the function showing the value of the account after t years is:
A = 540 * e^(0.091t)
To find the percentage of growth per year (APY), we can use the formula:
APY = (e^r - 1) * 100
Substituting r = 0.091, we find:
APY = (e^0.091 - 1) * 100 = 9.56%
So, the APY is approximately 9.56%, to the nearest hundredth of a percent.

For the right triangles below, find the values of the side lengths B and C .
Round your answers to the nearest tenth.
For the given right triangles the value of side b is [tex]4\sqrt{3}=6.9[/tex] meanwhile the value of side c is [tex]2.5\sqrt{2} =3.5[/tex].
RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem. The Pythagorean Theorem says (hypotenuse)²= (leg1)²+(leg2)². And the main trigonometric ratios are: sin (x) , cos (x) and tan (x) .
The question asks the values of the side lengths b and c. The variables b and c represent one of the sides of the right triangles.
Finding the side b - You should apply the trigonometric ratio sin (Ф). Knowing that: sin (Ф)=[tex]\frac{opposite\ side}{hypotenuse}[/tex] and sin (60)=[tex]\frac{\sqrt{3}}{2}[/tex], you can write:sin (60)=b/8
[tex]\frac{\sqrt{3}}{2}=\frac{b}{8} \\ \\ 2b=8\sqrt{3} \\ \\ b=4\sqrt{3}=6.9[/tex]

What is transversal?There are several different kinds of lines that can exist in geometry, including parallel, perpendicular, intersecting, and so on. A transversal is a different line that we have in addition to that. A road crossing two or more other roads or a railway crossing several other lines are examples of this. These convey the fundamental concept of a transversal. If two or more other lines in the Euclidean plane are parallel, transversals are crucial in determining this. Learn the definition of a transversal line in this article, along with how it can be used to create angles with both parallel and non-parallel lines. Study additional geometrical ideas here.
Given, I || h
Using the same internal property of transversal
81 + x = 180° (angle sum property)
x = 180 - 81
x = 99°
For (3y + 33), vertical opposite angle rule can be applied so
x = (3y + 33)
3y + 33 = 99°
3y = 99 - 33
3y = 66

A wine maker can make 14 bottles of wine with 80 pounds of grapes. If the wine maker picks 625 pounds of grapes, how many bottles of wine can be made? round to the nearest whole bottle.
Answer:First, we can calculate how many bottles of wine can be made per pound of grapes:
14 bottles / 80 pounds = 0.175 bottles / pound
Next, we can multiply this number by the number of pounds of grapes the wine maker has to find the total number of bottles of wine that can be made:
0.175 bottles / pound * 625 pounds = 110.31 bottles
Rounding to the nearest whole bottle, we find that the wine maker can make 110 bottles of wine with 625 pounds of grapes.

Oy2(x-50)² +625
O yz-(x +50)² +625
O y2(x +50)² +625
O yz-(x-50)² +625
The appropriate answer to that same previous information is y ≥ -(x-50)² + 25
Why does inequality matter?According to analysts, inequality promotes political dysfunction and slows down economic progress. Because wealthy households typically spend a smaller share of their earnings than do poorer households, concentrated riches lower the amount of demand within the economy. The economy may suffer if low-income families have fewer possibilities.
Assume that the equation is y = a(x-h)² + k
y - a (x-50)² + 625
Put (61,504) in the equation
504 = a(61 - 50)² + 625
504 = a.121+625

When the three principles are not collinear, a unique rectangle and square in Geometry and trigonometry are discovered. Triangles are polygons because they have sides and three corners. The points at which three sides of the triangle coincide are referred to as the triangle's edges. Three triangle angles are multiplied to generate 180 degrees.
given
FGH and JKL in the specified right angle
GF ≅ KJ ( one side of both right angle triangles) ( one side of both right angle triangles)
∠F≅ ∠J (right angle) (right angle)
FH ≅ JL (opposite side of both right angle triangles ) (other side of both right angle triangles )
Then ,
We can conclude that GH KL (hypotenuse of both right angle triangles)
In two right triangles, if the hypotenuse and one side of one triangle are identical to the hypotenuse and one side of the other triangle, then the two triangles are congruent according to the RHS congruence rule.
It is true that both triangles meet the prerequisites listed before. FGH and JKL are then consistent.
