Three friends decide to evenly split their bill at a restaurant. The total bill is $84.99 and they will have to pay an additional $5.10 tax. One of the friends determines that each person owes $45.04. Estimate the amount each person should owe. Is the friend's calculation reasonable? Select from the drop-down menus to complete the sentence. The friend's calculation because each person should owe about .
Given : The Total Bill at the Restaurant is $84.99
Given : The Additional Tax is $5.10
⇒ Total Bill Including the Tax is : (84.99 + 5.10) = $90.09
Given : Three Friends decide to evenly split their Bill
⇒ $90.09 should be Divided into 3 Equal Parts
[tex]\mathsf{\implies The\;Amount\;each\;person\;should\;owe\;is = (\frac{90.09}{3})}[/tex]
[tex]\mathsf{\implies The\;Amount\;each\;person\;should\;owe\;is = 30.03\;Dollars}[/tex]
His Friend Calculation is not Reasonable
The friend's calculation of each person owing $45.04 is not reasonable as the correct amount should be $30.03 per person when evenly splitting a bill of $84.99 with an additional $5.10 tax.
To determine whether the friend's calculation of $45.04 each for splitting a bill of $84.99 with an additional $5.10 tax is reasonable, let's calculate the correct amount each person should owe. First, we combine the total bill and tax: $84.99 + $5.10 = $90.09. Then, we divide this total by three, as there are three friends: $90.09 / 3 = $30.03 per person.
The friend's calculation is not reasonable because each person should owe about $30.03, not $45.04. The estimate of $45.04 is significantly higher than the accurate calculation.
One day jasmine earned $25.20 for 6 hours of work. Another day, she earned $16.80 for 4 hours of work. Which function shows how much jasmine earns (c) for working (h) for hours?
Jasmine earns $4.20 per hour of work. The function that represents her earnings (c) for working h hours is c = 4.2h.
Explanation:From the provided information, we know that Jasmine earns $25.20 for working for 6 hours one day, and $16.80 for working 4 hours the next day. The rate at which Jasmine is paid can be determined by dividing her earnings by the hours she works, otherwise known as her wage rate.
For the first day:
Wage rate = $25.20/6 = $4.20 per hour
For the second day:
Wage rate = $16.80/4 = $4.20 per hour
Thus, we can conclude that Jasmine earns $4.20 per hour. Therefore, the function for Jasmine's earnings (c) for working h hours is given by:
c = 4.2h
Where 'c' represents the total earnings and 'h' represents the hours worked.

What is the shortest driving distance from the animal shelter to the stadium?
Answer:
7 miles
Step-by-step explanation:
Four miles plus 3 miles = 7 miles
The shortest driving distance from the animal shelter to the stadium can be found using a map or a GPS system, which considers all possible routes and chooses the one with the least distance.
Explanation:The shortest driving distance between two locations, in this case, from an animal shelter to a stadium, can be discovered by using geographical tools such as a map or GPS system. These tools can provide data on distance with respect to various routes, allowing you to choose the shortest one.
For example, assume the animal shelter is at Place A, and the stadium is at Place B. The GPS system will analyze all possible routes from A to B, consider traffic conditions, road detours, and provide you with the option that covers the least amount of miles/kilometers and saves the most time. This is considered the shortest driving distance.

what is the r^2 value of the following data to three decimal places???
Answer:
0.783
Step-by-step explanation:
To find first r and then r square for the data
n statistics, the coefficient of determination, denoted R2 or r2 and pronounced "R squared", is the proportion of the variance in the dependent variable that is predictable from the independent variable(s).
correlation coefficient of x and y = Cov (x,y)/std dev x * std dev Y
Cov (x,y) = E(xy) -E(x)E(y)
Hence calculations would be as follows:
x y xy
1 2 2
2 10 20
5 5 25
7 18 126
10 25 250
Mean 5 12 84.6
Cov E(xy)-E(x)E(y) 24.6
r 0.884640297
r^2 0.782588454

to give money and spread awareness of homelessness Alaska made an organization and gets money for the homeless from fees from new members.There were 587 new members that were 18-24 years old and they have to pay $10 in fees.The rest who were older than 24 years old had to pay $15 in fees.If there are 1942 new members in total,how much money did Alaska contribute to stop homelessness?
Answer:
$26,195.
Step-by-step explanation:
total of new members(1942) - age group 18-24 (587)= new members(1355) to pay $15 each in fees.
1942-587=1355 x$15=20,325
next: take age group 18-24 (587)and multiple by $10 fee
587 x$10=5,870
last add both numbers together:
$20,325+ $5870=$26,195

Answer:
718 cubic inches
Step-by-step explanation:
The formula for a sphere is [tex]V=\frac{4}{3} \pi r^{3}[/tex]. A hemisphere is half this value. We will find the volume and then divide it in half. We substitute r=7 inches.
[tex]V=\frac{4}{3} \pi r^{3}\\V=\frac{4}{3} \pi (7^{3})\\V=\frac{4}{3} \pi (343)\\V=1,436 inches^3[/tex]

Audrey's parents give her $5 to play video games at the mall.Each games costs a quarter to play.which choice is NOT a correct method for determining the total #of games she can play. A.Take the #of dollars she has and divide it by 1/4. B.Take the # of dollars she has and multiply it by 4. C.Take the # of dollars she has and divide it by 0.25. D.Take the # of dollars she has and multiply by 0.25
Answer:
Step-by-step explanation:
If answer A works then so will Answer A. The reason is because 1/4 and 0.25 are equal to one another. The only comment you should recognize is that
5/0.25 is a whole lot easier to do than 5/(1/4)
B is the same thing as C when you apply the division by fractions rule.
D is the odd method out. Instead of 20 games (5 * 4) she will only get to play 4. That because she has 5 dollars and if you multiply by 0.25 you get 1.25 games
what percent of 20 is 6
Answer: 30 percent of 20 is 6.
_______________________________________________
Step-by-step explanation:
_______________________________________________
(n/100) * 20 = 6 ?
Solve for "n" .
_______________________________________________
Divide each side of the equation by "20" :
{ (n/100) * 20 } / 20 = 6 / 20 ;
to get:
n/100 = 6/20 ;
↔ 6/20 = n/100 ; solve for "n" ;
Look at the denominators:
20 * ? = 100 ?
100/ 20 = ? ;
100/20 = 5 ;
So, 20 * " 5" = 100 ;
Then 6* 5 = "n" (for the numerator, "n"; in : "n /100" ) ;
→ 6 * 5 = 30 ;
→ n = 30 .
_______________________________________________
Answer: 30 percent of 20 is 6.

Answer:
3. 9n + 6 = 78
5. see below
Step-by-step explanation:
3.
Let the number of adults be n. Each adult ticket costs $9, so the cost of n adult tickets is 9n. There is only one child, and a child's ticket is $6, so the cost of the child's ticket is 6. Adding the costs, you get 9n + 6. The total cost is $78, but the expression representing the total cost is 9n + 6, so 9n + 6 must equal 78. That is the equation.
9n + 6 = 78

In the figure, a║b. Find x+y in terms of z and w.
A. 180°+z−w
B. 180°–z−w
C. w−z
D. 180°+w−z
Answer:
A. 180°+z−w
Step-by-step explanation:
We know that x + w = 180 because they are same side exterior angles and a and b are parallel.
z=y because they are alternate interior angles and a and b are parallel.
x + w = 180
Solve for x by subtracting w from each side
x = 180-w
y =z
Lets find x+y
x+y
(180-w) +z
Rewriting
180+z-w
Answer:
A. 180º + z - w
Step-by-step explanation:
x + w = 180, because they are same side exterior angles, and are on opposite sides.
z = y, because if you move z down, then you will see that they overlap.
From x + w = 180, you can get x = 180 - w.
We are trying to find x + y in terms of w and z, so:
x = 180 - w
y = z
With that, you can assemble the expression, 180 - w + z.
If you re-arrange, you will get 180 + z - w.
Therefore, A is the answer.

2. 1|8
3. 8|0
4. 0|8
Answer:
4. 0|8
Step-by-step explanation:
key 3|4 = 34
The first digit is the tens place and the second digit is the ones place
8 can be represented as 08
0|8 would be 08
Answer:
4. 0 | 8
Step-by-step explanation:
Note that in the stem-and-leaf plot example given to us, 3 | 4 = 34.
From this, we can assume that the left side of | represents the tens place, while the right side of | represents the ones place value.
It is asking what the value 8 represents in 3 | 8. From the example that we see above, we know that the number given is 38. the value of 8 in this number represents the one's value.
0 | 8 is your best answer, for there is no tens place.

What is the sum of the √-2 and √-18?
Answer:
The sum is 4 i√2
Step-by-step explanation:
Both the numbers √-2 and √-18 are imaginary number and thus can be presented as
i√2 and i√18
On simplifying, the i√18 can be written as i√( 9 x 2)
Taking out square root of 9 we get-
3i√2
Thus the summation of i√2 and i√18 can be written as
i√2 + 3i√2
= 4 i√2
Answer:
The correct answer is (4 √2) i
Step-by-step explanation:
The sum we are looking is "x"
x= √-2+ √-18
By the Radical Properties of Multiplication ,
x=√-2 +√(-2*9)
x=√-2 +√-2* √9
Considering √-2= √((-1)*2)= √-1 *√2
According to the propriety of complex numbers , we can say
i=√-1
Replacing
x= i √2 + 3 i√2
The answer is x= (4 √2) i
