A ticket printer made 450 tickets in 9 minutes. Another ticket printer made tickets for 5 minutes at twice the rate of the first printer.
How many tickets did the second ticket printer make?
Answer:
500
Step-by-step explanation:
Rate at which first ticket printer works is 450/9 = 50 tickets per minute
Speed of second ticket printer is twice than that of the first.
So, speed of second printer is 100 tickets per minute.
In 5 minutes,second printer made 500 tickets

Solve for C. Show all work please.
C= 5/9 ( F - 32)
Answer:
Step-by-step explanation:
It is solved for C unless you C = 5/9 * F - 32*5/9
C = 5/9F - 17.8
=================
If you mean F, then Multiply both sides by 9/5
9/5 * C = F - 32
9/5 * C + 32 = F
=====================
A quick way to do this is to multiply by 2 and add 32
F = 2*C + 30
My wife, an American, always had to do this when she heard the daily temperatures in Canada.
first multiply both sides by 9/5 to get:
9/5C= F -32
Add 32 to both sides and transpose to get:
F=9/5C + 32
these are the formulas to translate between Fahrenheit and Celsius temperatures
Fahrenheit and Celsius meet at - 40 degrees
that is - 40 Fahrenheit = - 40 Celsius
So alternitive formulas for the conversations can be written:
F=9/5 (C+40) - 40
C=5/9 (F+40) - 40

Given:
The set of points.
To find:
Which set of points represents a function?
Solution:
A set of points represents a function if there exist a unique y-value for each x-value.
It option A, the set of points is
{(1,-2), (3,-5), (3,-2), (5,-7), (7, -8)}
This is not a function because there exist two y-values y=-5 and y=-2 for x=3.
It option B, the set of points is
{(0,1),(1,−3),(2,−5),(3,−7),(4,−9)}
This is a function because there exist a unique y-value for each x-value.
It option C, the set of points is
{(−1,1),(−1,3),(−1,5),(−1,7),(−1,9)}
This is not a function because there exist five y-values y=1,3,5,7,9 for x=-1.
It option D, the set of points is
{(−4,0),(−3,−1),(−3,1),(0,−2),(0,2)}
This is not a function because there exist two y-values y=-1 and y=1 for x=-3.
Therefore, the correct option is B.

What is the slope of the line that passes through the points (-9, 2)(−9,2) and (1, 27) ?(1,27)? Write your answer in simplest form. 1
Answer:
pls mark brainliest if possible:
slope is 1.5
Step-by-step explanation:
Slope = rise over run = (y2-y1)/(x2-x1)
choose y2 and corresponding x-coordinate is x2. If we choose 27 as y2, then:
x2 = 1
x1 = -9
y1 = 2
then plug everything into the equation
(27-2)/(1-(-9))
=15/10
= 1.5
slope is 1.5
hope this helps!

A Boeing 737 airplane travels about 500 miles per hour. The function d(t) = 500t represents the number
miles traveled in t hours. How far does the plane travel in 3.5 hours?
A. O 2,579.50 miles
B. 1,500.00 miles
C. 142.86 miles
D. 1,750.00 miles
Answer:
b
Step-by-step explanation:
The distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function d(t) = 500t represents the number of miles traveled in t hours.
Plug t = 3.5 hours in the equation of the function.
d(3.5) = 500(3.5)
d(3.5) = 1,750.0 miles
Thus, the distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.

The perimeter of the rectangle below is 112 units. Find the length of side VW . Write your answer without variables. Top YX: 4z Left YV: 5z + 2 Right XW: (blank) Bottom VW: (blank)
Answer:
[tex]VW = 33[/tex]
Step-by-step explanation:
See attachment for complete question
Given
[tex]VY = 4x - 1[/tex]
[tex]VW = 5x + 3[/tex]
[tex]Perimeter = 112[/tex]
Required
Determine the length of VW
Perimeter is calculated as:
[tex]Perimeter = 2 * (Width + Length)[/tex]
This gives:
[tex]Perimeter = 2 * (VW + VY)[/tex]
Substitute values for VW, VY and Perimeter
[tex]112 = 2 * (4x - 1 + 5x + 3)[/tex]
Collect Like Terms
[tex]112 = 2 * (4x + 5x -1 +3)[/tex]
[tex]112 = 2 * (9x +2)[/tex]
Divide through by 2
[tex]56 = 9x + 2[/tex]
Collect Like Terms
[tex]9x = 56 - 2[/tex]
[tex]9x = 54[/tex]
[tex]x = 54/9[/tex]
[tex]x = 6[/tex]
Substitute 6 for x in [tex]VW = 5x + 3[/tex]
[tex]VW = 5 * 6 + 3[/tex]
[tex]VW = 30 + 3[/tex]
[tex]VW = 33[/tex]
Sally is making bouquets of flowers with the ratio of red to white flowers being 2:3. If Sally used 12 red flowers, how many white flowers will she use?
Answer:
18 white flowers
Step-by-step explanation:
We are given ratio:
Red : White
2 : 3
If Sally used 12 red flowers, how many white flowers will she use?
Let the number of white flowers Sally uses be represented by x
This is calculated as:
2/3 = 12/x
Cross Multiply
2 × x = 3 × 12
x = 3 × 12/2
x = 18 white flowers
Therefore, if Sally used 12 red flowers, the number of white flowers will she use is 18 white flowers.

A sequence has an initial value (I) of -17 and its fourth term (a4) is 35. What is its general equation? Its 14th term?
Also, A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?
Answer:
The sequence is an Arthemtic ProgressionAn=A1+(n-1)d
A1 is first term, An is nth term, n is number of term, and d is common difference
therefore
A4=35, A1= -17
A4=A1+(4-1)d
35= -17+3d
35+17=3d
52=3d
52/3=3d/3
14=d
common diffrence(d)=14
The general solution is given byAn= -17+(n-1)14
An= -17+14n-14
An= -31+14n
An= 14n-31
A14 term, means n=14
From An=A1+(n-1)d
A14= -17+(14-1)14
= -17+(13×14)
= -17+182
= 165.
Therfore, the 14th term is 165.
2. A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?
solution
common ratio(r)=4/5
eighth term(G8)=393216/3125
From Gn= G1r^(n-1)
G8 means n=8
G8=G1r^(n-1)
393216/3125=G1(4/5)^(8-1)
393216/3125=G1(4/5)^7
G1=(393216/3125)/(4/5)^7
G1=600
The first term is given by G1=600
ThereforeThe General equation is given by
The General equation is given by Gn= 600(4/5)^(n-1)
3rd term (G3)
G3= G1(4/5)^(3-1) where n=3,
=600(4/5)^2
=600(16/25)
=384
Therefore, the 3rd term is given by G3= 384.

Miguel's cat, Chester, weighs 6.8 pounds. Chester's vet tells Miguel to feed the cat 3 4 of an ounce of canned food daily for each pound of body weight. The next morning, Miguel opens a new can of food to feed Chester. If the can holds 5.5 ounces, how much food will be left after one day? Write your answer as a whole number, decimal, fraction, or mixed number. Simplify any fractions.
Answer:
0.4 ounces
Step-by-step explanation:
In a day
Miguel is to feed Chester ,
Chester can eat 3/4 of an ounce for each pound of body weight.
Chester weighs 6.8 pounds
Hence:
1 pound = 3/4 ounce
6.8 pounds = x ounces
Cross Multiply
x = 6.8 × (3/4) ounces
x = 5.1 ounces
Chester is to be fed 5.1 ounces of food each day.
The amount of food left after 1 day
= 5.5 ounces - 5.1 ounces
= 0.4 ounces
Hence, 0.4 ounces of food is left after 1 day

Area = 1/2 * 8.7 * 5 = 21.75
There are 4 such triangles. The total area = 4 * 21.75 = 87 sqr in

He prime factorization of a number is 2 cubed times 3 squared times 5. Which is a true statement about the factors of the number? Fifteen is a factor of the number because both 3 and 5 are prime factors. Fifteen is not a factor of the number because 15 is odd and the number is even. Sixteen is a factor for the number because 2 cubed = 8 and 16 is divisible by 8. Sixteen is not a factor of the number because the exponent of 2 is not even.
Answer:
Fifteen is a factor of the number because both 3 and 5 are prime factors.
Step-by-step explanation:
The computation is shown below:
The cube of 2 is
= 2^3
= 8
The square of 3 is
= 3^2
= 9
Now if we multiplied the 3 digits that it would be
= 8 × 9 × 5
= 360
As we know that the 15 is a factor of 360
Therefore the first option is correct
i.e.
Fifteen is a factor of the number because both 3 and 5 are prime factors.
