Step-by-step explanation:
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.

It says to find the value of x.
Answer:
x = 23
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the third angle forms a straight angle with 100°, hence
third angle in triangle = 180° - 100° = 80°
Summing the 3 angles gives
2x + 3 + 80 + 51 = 180
2x + 134 = 180 ( subtract 134 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
Remy drinks 214 cups of water every 145 hours.
How many cups of water does he drink in 1 hour?
Answer:
Approximately 1.5 cups/hour
Step-by-step explanation:
Divide 214 cups by 145 hours.
(214 cups)/(145 hours) = 1.47586... cups/hour
Remy drinks around 1.47 cups of water in an hour. This was calculated by dividing the total cups (214) by total hours (145).
Explanation:To solve this question, we need to calculate the rate at which Remy drinks 214 cups of water every 145 hours. This can be done by dividing the total number of cups by the total number of hours.
So, the formula we have is:Cups per hour = Total Cups / Total hours
This gives us:Cups per hour = 214 / 145
After calculating this, you will find that Remy drinks approximately 1.47 cups of water in 1 hour.

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.

In what direction and by how many units is the graph of f(x) = −3 cos(2x − π) + 2 vertically and horizontally shifted
Answer:
Vertical shift is 2 units top and horizontal shift is [tex]\frac{\pi }{2}[/tex] units to the right
Step-by-step explanation:
Consider the function f(x) = a cos(bx + c) + d.
In this graph, the horizontal shift is -c/b and the vertical shift is d.
Let's compare our graph, f(x) = -3 cos(2x - π) + 2 with this graph.
Here, a = -3, b = 2, c = -π and d = 2.
So, vertical shift = d = 2 units top and
horizontal shift = [tex]-\frac{c}{b} =-\frac{-\pi }{2} =\frac{\pi}{2}[/tex] units to the right.

Answer:
a) x=38
b) x=19
Step-by-step explanation:
a) The interior angles at L and M can be found by subtracting 134 and 84 from 180 respectively:
∠L = 180 - 134 = 46
∠M = 180 - 84 = 96
The angles of a triangle sum up to 180, so x + 46 + 96 = 180.
From this you find that x = 180 - 46 - 96 = 38
b) Because YZ and XW are parallel, ∠Y=∠W = 2x
The sum of the angles in the triangle must be 180, so
3x-5 + 90 + 2x = 180
Which simplifies to
5x +85 = 180
5x = 95
x = 19
Answer:
a) x = 38°; b) x = 19°
Step-by-step explanation:
a)
∠OLM = 180 - 134 = 46° Supplementary angles
∠OML =180 - 84 = 96° Supplementary angles
x + 46 + 96 = 180 Interior angles of triangle
x + 142 = 180
x = 38°
===============
b)
∠XWY + 3x - 5 + 90 = 180 Interior angles of triangle
∠XWY + 3x + 85 = 180
(1) ∠XWY + 3x = 95
∠XWY = 2x
(2) ∠XWY - 2x = 0 Alternate interior angles
5x = 95 [2 subtracted from (1)]
x = 19°
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.

the sum of two numbers that differ by 3 is x, what is the value of the greater of the two numbers?
Answer:
Step-by-step explanation:
You really don't have enough information to solve this with one answer. You want a value for y and there is no what to limit it to just 1 set of values. For example if x = 23 then
x = y + y - 3
x = 2y - 3
23 = 2y - 3 Add three to both sides
23+3 = 2y Combine
26 = 2y Divide by 2
26/2 = 2y/2 Do the division
13 = y
The smaller number is 13 - 3 = 10
Their sum is 13 + 10=23 But that answer is not unique.
====================
Suppose x = 13
13 = 2y - 3 Add 3
13 + 3 = 2y
16 = 2y
y =8
The larger number = 8
The smaller number = 5
=======================
The best I can do is give you the equation which is
x = 2y - 3
