Shen rented a truck for one day. There was a base fee $18.95 and there was an additional charge of 83 cents for each mile driven. Shen had to pay $213.17 when he returned the truck. For how many miles did he drive the truck
Answer:
234 miles
Step-by-step explanation:
Lets set the variable 'n' as the number of miles driven. We can set up the following equation:
18.95 + 0.83n = 213.17
Now, all we have to do is solve it. We can get 0.83n = 194.22, so n = 194.22/0.83 = 234 miles
find the number of sides of a regular prism which has 10 faces and 12 vertices
I NEED THE ANSWER THE QUESTION QUICK
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.

Kai bought his younger sister, Loni, a sticker book and 12 stickers. Each week he gives his sister two new stickers. Let w represent the number of weeks that Loni collects stickers, and let s represent the total number of stickers she has collected. a. Determine the independent and dependent variables. The number of weeks, w, is the ? variable. The total number of stickers, s, is the ? variable.
Answer:
w = independent variables = dependent variable======================================================
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
Plug in w = 0 to find that s = 12. This is the starting amount of stickers.Plug in w = 1 to find s = 14. This is the number of stickers after 1 week.Plug in w = 2 to find s = 16. This is the number of stickers after 2 weeks.And so on. Each time 'w' goes up by 1, 's' goes up by 2.
Which inequality shows the region represented by the
inequality in vertex form?
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
121a = -121
a = -1
y = -(x-50)² + 625
Hence, y ≥ - (x-50)² + 625

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,

The subtotal for Abdiel's takeout order is $21.50. What will Abdiel's total be if he uses a coupon for 10% off the subtotal and leaves a 20% tip before the discount? (2 points)
$22.15
$27.95
$23.22
$23.65
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.

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.

(a) The perimeter of a rectangular field is 350 m.
If the width of the field is 79 m, what is its length?
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.
$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.

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.

The phone company Splint has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 390 minutes, the monthly cost will be $178. If the customer uses 940 minutes, the monthly cost will be $398.
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.

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
