Solve the right triangle

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

Answer:

======================================================

Reason:

The number of weeks can be any number from the set {0,1,2,3,...} so we say that this value is independent. It does not depend on the number of stickers.

But the number of stickers does depend on the number of weeks. As w changes, so does the value of 's'.

The equation would be:  s = 2w+12

And so on. Each time 'w' goes up by 1, 's' goes up by 2.

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.

Therefore , the solution of the given problem of equation comes out to be total cost for 866 minutes is $1487.

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 people in Indiana residents is given by the equation

A = 5,750,000 or 5.75 million

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of people in Indiana residents aged 5 years and older be A

Now , the equation will be

Substituting the values in the equation , we get

The percentage of population residents aged 5 years and older = 5.6 %

The number of residents aged 5 years and older = 322,000

So , the total population A is calculated as

( 5.6 % ) of A = 322,000

On simplifying the equation , we get

( 5.6 / 100 ) A = 322,000

Divide by 6.6 on both sides of the equation , we get

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.

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.

Answer: To calculate the total, we need to first calculate the discount and then the tip.

First, calculate the discount: $21.50 x 10% = $2.15

Then, subtract the discount from the subtotal: $21.50 - $2.15 = $19.35

Next, calculate the tip: $19.35 x 20% = $3.87

Finally, add the tip to the subtotal after the discount to find the total: $19.35 + $3.87 = $23.22

Therefore, Abdiel's total would be $23.22 if he uses a coupon for 10% off the subtotal and leaves a 20% tip before the discount.

The number of phones and accessories sold are 8 and 24 respectively.

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

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.

The appropriate answer to that same previous information is y ≥ -(x-50)² + 25

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

Answer: 96 m.

Step-by-step explanation: Let's call the length of the rectangular field "L".

We know the perimeter of the field is equal to the sum of all its sides, so:

350 = 2L + 2 * 79

Expanding the right side, we have:

350 = 2L + 158

Subtracting 158 from both sides:

192 = 2L

Dividing both sides by 2:

L = 96 m

So the length of the rectangular field is 96 m.
