The Science Club wants to print stickers to promote their club and an interest in science. They got a quote to print the stickers from two printers. Pop Art Printing would charge a $25 setup fee and $0.05 per sticker. Sticky Slogans would charge a $12 setup fee and $0.09 per sticker. Write a system of equations that can be used to find the number of stickers for the cost of both printers to be equal.
Answer:
The system of equations =
25 + 0.05x = 12 + 0.09x
The number of stickers where the cost of both printers to be equal is 325 stickers
Step-by-step explanation:
Let the number of stickers = x
Printer 1
Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.
$25 + $0.05× x
25 + 0.05x
Printer 2
Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.
$12 + $0.09 × x
12 + 0.09x
We equate both equations together
The system of equations =
25 + 0.05x = 12 + 0.09x
Collect like terms
25 - 12 = 0.09x - 0.05x
13 = 0.04x
x = 13/0.04
x = 325 stickers
Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers

Which logarithmic equation is equivalent to this exponential equation?
2,400 = 7,500(10) *
A.
B.
I = log
log (3)
I = -log ()
I = -log (*)
I = log (1)
OC.
D.
Answer:
B.
Step-by-step explanation:
2,400 = 7,500[tex](10)^{x}[/tex]
First of all, you want to isolate the [tex](10)^{x}[/tex] by dividing each side by 7,500.
After doing this, you will get
[tex]\frac{2400}{7500}[/tex] = [tex](10)^{-x}[/tex].
Putting this in the logarithmic form, you get [tex]log_{10}[/tex] [tex]\frac{2400}{7500}[/tex] = - x
To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get [tex]-log_{10} \frac{2400}{7500}[/tex] = x.
When you simplify 2400/7500, you get 8/25, so the answer is B.
Hope this helps!
You can use the definition of logarithm here.

how to convert 3500mm into meter
Answer: 3.5 meters
Step-by-step explanation:
First and foremost, we need to note that 1000 millimeters = 1 meter. Therefore, for us to convert 3500 millimeter to meters, we have to divide it by 1000. This will be:
= 3500/1000
= 3.5 meters
Sebastian is ordering a taxi from an online taxi service. The taxi charges $3 just for
the pickup and then an additional $0.75 per mile driven. How much would a taxi ride
cost if Sebastian is riding for 10 miles? How much would a taxi ride cost that is m
miles long?
Answer:
10:50
Step-by-step explanation:
Answer:
$10.50 for 10 miles & 0.75m+3 for "m" miles
Step-by-step explanation:
if the taxi charges $3 just for showing up, then in the formula (y=mx+b) 3 would be your "b"
y = mx + 3
if the taxi is charging $0.75 per mile, the mile will be your "x" in the formula, and 0.75 will represent your "m" in the formula
y = 0.75x + 3 - this is your equation for "m" miles
to find how much for 10 miles, substitute 10 for "x" in your formula
y = 0.75 (10) +3
y = 10.50
so it is $10.50 for 10 miles, including the 3 dollar pick up fee.

make x the subject formula 5x=t
Answer:
x=t/5
Step-by-step explanation:
5x=t
multiply both sides by 5 to make x the subject
x=t/5
Answer: 5x=t
x=t/5(Ans)
Step-by-step explanation:In order to make x the subject,We can start by removing the 5 that is multiplied with x.To do that divide both sides with 5. 5x divided by 5 is x and t divided by 5 is t/5.Therefore the final answer after making x the subject will be x=t/5.
(2, -4), (x, y) , A , and B all lie on the line. Find an equation relating x and y.
Answer:
An equation relating x and y is:
y = 3/4x - 5.5
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the points
(2, -4), (x, y), A(6, -1), and B(10, 2)
Taking any two points let say A(6, -1), and B(10, 2) to determine the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(6,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:2\right)[/tex]
[tex]m=\frac{2-\left(-1\right)}{10-6}[/tex]
Refine
[tex]m=\frac{3}{4}[/tex]
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = -5.5
Thus, the y-intercept b = -5.5
Thus, substituting b = -5.5 and m = 3/4 in the slope-intercept form of the line equation
y = mx+b
y = 3/4x + (-5.5)
y = 3/4x - 5.5
Therefore, an equation relating x and y is:
y = 3/4x - 5.5

Another Eurasian lynx traveled for 301 days. It traveled a distance of 77.8 miles. How many miles per week did it travel
Answer: 1.8 miles per week
Step-by-step explanation:
The European lynx travelled for 301 days and in that time covered a distance of 77.8 miles.
Convert the number of days to weeks:
= 301 / 7
= 43 weeks
If it travelled 77.8 miles in 43 weeks, its speed was:
= 77.8 / 43
= 1.8 miles per week
If EF is the perpendicular bisector of CD, find x.
Answer:
Step-by-step explanation:
A Perpendicular Bisector cuts a segment into two equal parts. We already know that 4x+19 and 6x-7 are both equal.
So then, you would start with 6x-7 = 4x+19.
6x-7 = 4x+19
Subtract -4x from both sides
2x-7 = 19
Add 7 to both sides
2x = 26
Divide both sides by two
x= 13
You only need x, so you're done.
(I'm like 90 percent sure this is wrong man don take my word for it bro).
The value of x will be 13.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
EF is the perpendicular bisector of CD.
Measure of length CE = 4x + 19
Measure of length ED = 6x - 7
Now,
Since, EF is the perpendicular bisector of CD.
So, We can formulate;
⇒ Δ EFC ≅ Δ EFD
Hence, Measure of length CE = Measure of length DE
Substitute all the values, we get;
⇒ 4x + 19 = 6x - 7
Solve for x as;
⇒ 4x + 19 = 6x - 7
Subtract 6x both side, we get;
⇒ 4x - 6x + 19 = 6x - 7 - 6x
⇒ - 2x + 19 = - 7
Subtract 19 both side,
⇒ - 2x + 19 - 19 = - 7 - 19
⇒ - 2x = - 26
Divide by - 2, we get;
⇒ x = 13
Thus, The value of x will be 13.

Celesta used to spend 90 minutes a day on the phone. Now she spends 60 minutes a day. What is the PERCENT DECREASE?
Answer:
-210
Step-by-step explanation:
The percent decrease in the time taken by Celesta is 33.33%.
What is Percentage?Percentage of a number is the parts per 100. Or percentage of a number can be calculated by dividing the number with the whole with respect to which we are finding the percentage of the number and then multiply with 100.
Percentage is a dimensionless number because percentage is not measured by any units.
Percentage decrease can be calculated by the formula,
Percentage Decrease = [(Original value - New value) / Original value] × 100
Time that Celesta used to spend on the phone a day = 90 minutes
Original value = 90
Now, celesta spends 60 minutes a day
New value = 60
Percentage decrease = [(90 - 60) / 90] × 100
= [30 / 90] × 100
= [1 / 3] × 100
= 33.33 %
Hence the percent decrease in the time taken by Celesta in a day is 33.33%.

A container in the shape of a rectangular prism has a base with an area of 19 1/2 square inches. If the container is filled with water to a height of 4 1/2 inches, how much water is in the container?
Answer: Water in the container = 87.75 cu.inches.
Step-by-step explanation:
Formula: Volume of rectangular prism = Base area x height
Base area = [tex]19\dfrac12[/tex] sq. inches Height = [tex]4\dfrac12[/tex] inches
So,
Volume of container = [tex]19\dfrac12\times4\dfrac12\text{ cu.inches}[/tex]
[tex]=\dfrac{39}{2}\times\dfrac{9}{2}\text{ cu.inches}[/tex]

the height of a hat is shaped like a cone is 10 inches. the volume of thw hat is 30(pi) cubic inches. what is the diameter of the hat?
Answer:
3.38pi
Step-by-step explanation:
Using simple math and the equation for finding the volume of a sphere, we can see that by taking the height of 10, and the volume of 30, that with that information we can deduce that the radius of the cone would be 1.69pi. With this information, we know the radius is half of the diameter. Therefore, we multiply 1.69 by 2, to get our end result, 3.36pi
