A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled. Part A: If the total cost of the fare was $41.00, then which of the following equations can be used to determine the number of miles traveled, x?What is the total number of miles traveled, x, if the fare was $41.00?
Answers
Answer:
5 + 3x = 41
x = 12 miles
Step-by-step explanation:
A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled.
Let x is the number of miles traveled.
If the total cost of the fare was $41.00 then
5 + 3x = 41 eq. 1
The above equation can be used to determine the number of miles traveled.
Solving the equation for x,
5 + 3x = 41
3x = 41 - 5
3x = 36
x = 36/3
x = 12 miles
Therefore, 12 is the total number of miles traveled if the fare was $41.00.

4(t+25) = (t+50) - 4 (0.15t)
Answers
Answer:
4(t+25) = (t+50) - 4 (0.15t)
4t + 100 = t + 50 - 0.6t
4t + 100 = 50 + 0.4t
4t - 0.4t + 100 = 50 + 0.4t - 0.4t
3.6t + 100 = 50
3.6t + 100 - 100 = 50 - 100
3.6t = -50
3.6t / 3.6 = -50 / 3.6
t = - 13.9

Two fifths of the performance were sold out. There were 15 performances that were not sold out. a. How many performances were there? b. What was the ratio sold out to not sold out performances?
Answers
Answer:
25
2:3
Step-by-step explanation:
2/5 were sold out
5/5 - 2/5 = 3/5
That means 3/5 were not sold out
p = performances
there were 15 that were not sold out
3/5 * p = 15
Multiply each side by 5/3
5/3 *3/5 p = 15*5/3
p = 25
There were 25 performances
sold out to not sold out
2/5 : 3/5
Multiply by 5

A container shapes like an inverted cone holds 96 cubic centimeters of water. The height of the cup is 14 centimeters. Find the length of the diameter?
Answers
Answer:
Cone Volume = (PI * radius^2 * height) / 3
96 cc = (PI * radius^2 * 14) / 3
(96 * 3) / (PI * 14) = radius^2
radius ^ 2 = 6.5480890872
radius = 2.5589234235
diameter = radius *2 = 5.117846847 cm
diameter = 5.12 cm (rounded)

Answers
Answer:
Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.
Step-by-step explanation:
First of all we know that the total surface are that Calvin is painting is 115 square feet.
The rate at which Calvin is painting refers to the surface area he covers every 2 minutes. This is 2.5 square feet every 2 minutes.
we can set up a relation to solve this problem
If Calvin paints [tex]2.5 ft^{2}[/tex] in 2 minutes
He will paint [tex]115 ft^{2}[/tex] in [tex]x[/tex] minutes
By cross multiplying, we have [tex]x= \frac{2 \times 115}{2.5}=92 minutes[/tex]
Hence Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.

Nguyen is decorating the room for her sister’s baby shower party. She is wrapping Vietnamese conical hats in baby prints tissue paper to decorate the tables and some shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
Answers
Answer:
She needs 301.8 in² of tissue paper.
Step-by-step explanation:
In order to calculate the amount of tissue paper she needs to make 21 hats, we need to find the area of each hat and multiply it by the total number of hats she wants to make.
Since the Vietnamese conical hats are hollow and don't have a base, we need to find the area of the it's lateral walls, this is given by the following expression:
lateral area = pi*r*l
r = d/2 = 16/2 = 8 in
We were given the height, but we need the slant height, therefore:
l = sqrt(r² + h²) = sqrt(8² + 9²) = sqrt(64 + 81) = sqrt(145) = 12.041 in
Then the lateral area is:
lateral area = pi*8*12.0141 = 301.8 in²
She needs 301.8 in² of tissue paper.

The function h ( x ) = 1 x − 1 h ( x ) = 1 x - 1 can be expressed in the form f ( g ( x ) ) f ( g ( x ) ) , where g ( x ) = ( x − 1 ) g ( x ) = ( x - 1 ) , and f ( x ) f ( x ) is defined as:
Answers
Answer: f(x) = 1^(x + 1)
Step-by-step explanation:
we have that h(x) = 1^x
and h(x) = f(g(x))
This mean that we are evaluating the function f(y) in the point y = g(x)
where g(x) = x - 1
then:
f(g(x) = f(x - 1) = h(x) = 1^x
then we should have that:
f(x) = 1^(x + 1)
then:
f(x - 1) = 1^(x - 1 + 1) = 1^x

Answers
Question:
Let [tex]p=x^2-2[/tex] .
Which equation is equivalent to in terms of p ?
Answer:
[tex]p^2+18=9p[/tex] or [tex]p^2+18 - 9p = 0[/tex]
Step-by-step explanation:
Given
[tex]p=x^2-2[/tex] .
Required
Find the equation equivalent to [tex](x^2-2)^2+18=9x^2-18[/tex]
To get the equation equivalent to the given expression, we simply simplify [tex](x^2-2)^2+18=9x^2-18[/tex] and solve in terms of p
[tex](x^2-2)^2+18=9x^2-18[/tex]
Factorize expression on the right hand side
[tex](x^2-2)^2+18=9(x^2-2)[/tex]
Substitute [tex]x^2 - 2[/tex] for p
[tex](x^2-2)^2+18=9(x^2-2)[/tex] becomes
[tex]p^2+18=9p[/tex]
Hence, equation [tex]p^2+18=9p[/tex] is equivalent to [tex](x^2-2)^2+18=9x^2-18[/tex]
Solving further to get the value of p
[tex]p^2+18=9p[/tex]
Subtract 9p from both sides
[tex]p^2+18 - 9p = 9p - 9p[/tex]
[tex]p^2+18 - 9p = 0[/tex]
Rearrange
[tex]p^2 - 9p +18 = 0[/tex]
Factorize
[tex]p^2 - 6p - 3p +18 = 0[/tex]
[tex]p(p - 6) - 3(p -6) = 0[/tex]
[tex](p - 3)(p -6) = 0[/tex]
p - 3 = 0 or p - 6 = 0
p = 3 or p = 6
Answer:
p^2-18+9p=0
