The cost to buy tickets online for a dance show is $60 per ticket. a. Write a function that represents the cost C(x) (in $) for x tickets to the show. b. There is a sales tax of 5.5% and a processing fee of $8.00 for a group of tickets. Write a function that represents the total cost T(a) for a dollars spent on tickets. c. Find (T ∘ C)(x). d. Find (T ∘ C)(6) and interpret its meaning in the context of this problem.
Step-by-step explanation:
Given
cost of ticket=$60
a. the cost of x tickets is
C(x)=60x
b. sale tax of 5.5% of $60 is 5.5/100*60
0.55*60=$3.3
processing fee = $8
the total cost T(a) for a dollars spent on tickets.
T(a)=60a+3.3+8
T(a)=60a+11.3
c. Find (T ∘ C)(x).
T(x)=60x+11.3
d. Find (T ∘ C)(6)
T(6)=60*6+11.3
T(6)=360+11.3
T(6)=$371.3
This means that for 6 tickets with a tax of 5.5% and a processing fee of $8 the cost will be $371.3

Answer:
the tripled recipe of peaches is 2 or 6/3
the tripled amount of rhubarb would be 21/2 or [tex]10\frac{1}{2}[/tex]
Step-by-step explanation:
for the first part, just multiply the top number (2) by 3. (that would be 6)
then, divide that by the bottom number (3).
6/3 = 2.
for the second part, you need to convert the mixed number to an improper fraction.
[tex]3\frac{1}{2}[/tex] as an improper fraction is [tex]\frac{7}{2}[/tex]
now, multiply the top number (7) by 3. (that would be 21)
then. divide that by the bottom number. (2)
21/2 = [tex]10\frac{1}{2}[/tex]
What is the slope of the line
represented by the equation
2y = 5x + 4?
Answer: The slope is 5/2.
Step-by-step explanation:
Convert the equation into slope intercept form, ( y=mx+b)
2y = 5x + 4 Divide each side by 2
y = 5/2x + 2 In this form the slope will be the coefficient of x variable.
The coefficient is the number that comes before x.
In this case, the slope is 5/2.
The volume of a pyramid is V = 1/2 Ah. If V = 60 when h = 9, find A.
Answer:
Here,
Volume of pyramid (V) = 1/2 ×A×H
Given, V= 60 , H= 9
Now place the value of V and H in :
V= 1/2 ×A×H
60= 1/2 ×A × 9
60×2= 9A
120/9 = A
Hence, A= 120/9

A bus covers a distance of 90km at a uniform speed. Had the speed been 15km/hour it would have taken 30 minutes less for the journey. Find the original speed of the bus.
Answer:
Step-by-step explanation
Let's say d = distance, r = speed and t = time
We know the distance formula is :
distance = speed x time
d = r multiplied by t
d = rt
If the speed is 15km/hr, the time would be 30 minutes shorter.
Since d = rt,
90 = 15t
t = 6,
This means the time taken for the bus to complete the journey at 15km/hr would be 6hrs.
Originally though, the journey takes 30 minutes longer.
So we can say t = 6.5 hrs , and we know d = 90
Now we use the distance formula:
d = rt, since we want to find the original speed, we want to find r.
Speed = distance/time
r = d/t
r = 90/6.5
r = 180/13
Therefore the original speed is 180/13 km/hr

Solve for j.
20 − 17j = –18j
j =
Answer:
[tex]\boxed {j = -20}[/tex]
Step-by-step explanation:
-Solve for the value of [tex]j[/tex]:
[tex]20 - 17j = -18j[/tex]
-Take [tex]18j[/tex]and add it to [tex]17j[/tex]:
[tex]20 - 17j + 18j = -18j + 18j[/tex]
[tex]20 + j = 0[/tex]
-Subtract both sides by [tex]20[/tex]:
[tex]20 - 20 + j = 0 -20[/tex]
[tex]\boxed {j = -20}[/tex]
So, the value of [tex]j[/tex] is [tex]-20[/tex].

ASAP PLEASE ANSWERRR find the value of x. 3x+34=16
Answer:
-6
Step-by-step explanation:
subtract 3 from both sides and that leaves 3x=-18
then divide 3 by -18 and that equals -6
Answer:
x= -6
Step-by-step explanation:
Step 1: Subtract 34 from both sides.
3x+34−34=16−34
3x=−18
Step 2: Divide both sides by 3.
3x /3 = −18 /3
x=−6

I cut along piece of wood into 50cm pieces I manage to cut w, pieces of wood and there is 20cm left over . How long was the wood to start with
Answer:
50w+20 (cm)
Step-by-step explanation:
There would be w pieces of 50cm wood pieces and one 20cm wood piece.
wood length = 50w +20
Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces
Result = length * number
Result = 50 * w
Result = 50w
Lastly, add the leftover to get the actual length of the wood
Woodlengrh = result + leftover
Substitute 50w for Result and 20 for Leftover
woodlength = 50w + 20
Hence, the length of the wood is 50w + 20
The peak of Mount Everest, Earth's tallest point, is about 5 1/2 miles above sea level. The bottom of the Mariana Trench, Earth's deepest point, is about 6 9/10 miles below sea level. If you could place Mount Everest at the bottom of the Mariana Trench, how far from sea level would its peak be?
Answer:
11 7/10 miles below sea level
Step-by-step explanation:
Given the following :
Peak of Mount everest = 5 1/2 miles above sea level
Bottom of Mariana trench = 6 9/10 miles below sea level
If mount everest is placed at the bottom of Mariana trench
. It's be will be :
Since sea level could be considered as a 0 point;
Adding the height and depth of both should give us the depth below sea level:
(6 9/10 + 5 1/2) miles
6 + 5 (9/10 + 1/2)
11 (9 + 5)/10
11 14/10
11 7/10
= 11 7/10 miles below sea level

John earned $36 for 8 hours of work. Earnings are directly proportional with hours worked.how much did he earn when he worked 30 hours.
Answer:
$135
Step-by-step explanation:
First, find the unit rate of money earned (36/8=4.5)
Then, multiply the unit rate of money earned by 30 (4.5 x 30 = $135)
I apologize if my wording is incorrect.
The total earnings for the 30 hours is $1350 if John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.
Earnings ∝ hours
E ∝ T
E = kT
Here k is the constant
36 = 8k
k = 36/8
E = (36/8)T
Plug T = 30
E = (36/8)(30)
E = $1350
Thus, the total earnings for the 30 hours is $1350 if John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.
