Answer:
She bought 5 pounds of coffee.
Step-by-step explanation:
We are looking for how many pounds so pounds would be your x.
each pound costs $8.62.
You are taking the money she payed for the coffee away from the $70 she received.
Set up your equation
70 - 8.62x = 26.90
Solve for x
Subtract 70 from both sides 70-70 (Cancels out) - 8.62x= 26.90-70
-8.62x = -43.10
Divide -8.62 from each side. -8.62/-8.62(cancels out) x = -43.10/-8.62 (two negative numbers multiplied or divided by each other makes a positive)
x=5
a printer can print 27 pages in 4.5 minutes. how much time does it take to print 324 pages
Answer:
54
Step-by-step explanation:
27pages=4.5minutes
[tex]1 = \frac{4.5}{27} [/tex]
[tex]324 = \frac{4.5}{27} \times 324[/tex]
[tex]324 = 4.5 \times 12[/tex]
324pages=54minutes
Hence, the printer can print 324pages in 54 minutes
4/5 minus 1/3 plz i need help
Answer:
7/15
Step-by-step explanation:
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 4 by 3, and get 12.
Then we multiply 1 by 5, and get 5.
Next we give both terms new denominators -- 5 × 3 = 15.
So now our fractions look like this:
12
15
−
5
15
Step 2
Since our denominators match, we can subtract the numerators.
12 − 5 = 7
So the answer is:
7
15
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 7. So we're done reducing.

Answer:
22/90.
Step-by-step explanation:
0.24444... * 100 = 24.4444...
0.244444.. * 10 = 2.44444....
Subtract:
0.244444.. * 90 = 22
So the required fraction is 22/90.
Which is a zero of the quadratic function f(x) = 16x?? + 32x - 9?
Answer:
f(x) = 16x2 + 32x - 9
To find the "zeros", set f(x) = 0:
0 = 16x2 + 32x - 9
The equation is solvable by factoring or by using the quadratic formula. The factors (use the "ac" method) are:
0 = (4x-1)(4x+9)
x = 1/4 = 0.25 and x = -9/4 = -2.25
Step-by-step explanation:
The zero of the quadratic function f(x) = 16x² + 32x - 9 is x = -2.25. Thus, the correct answer is option B.
To find the zero of the quadratic function f(x) = 16x² + 32x - 9, we need to solve the equation f(x) = 0.
Setting the equation equal to zero:
16x² + 32x - 9 = 0
To solve this quadratic equation, we can use the quadratic formula:
[tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
For our equation, the coefficients are:
a = 16
b = 32
c = -9
Substituting these values into the quadratic formula:
[tex]x = \dfrac{-32\pm\sqrt{32^2-4\times16\times-9}}{2\times16}\\\\x=\dfrac{-32\pm \:40}{32}\\\\x=\dfrac{-32+40}{32},\dfrac{-32-40}{32}[/tex]
Simplifying further:
x = 8 / 32
= 1/4
= 0.25
x = -72 / 32
= -9/4
= -2.25
Therefore, the zero of the quadratic function f(x) = 16x² + 32x - 9 is x = -2.25.

How do I solve this arithmetic problem?
Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

The function represents the cost in dollars of playing a video game in terms of time spent playing in months.
y = 15x +45
What can you interpret from this function?
It costs $15 a month to play the video game.
There is an initial cost of $45 to play the video game.
There is an initial cost of $15 to play the video game.
It costs $45 a month to play the video game.
The y-variable represents the cost in dollars, and the x-variable represents the number of months.
The y-variable represents the number of months, and the x-variable represents the cost in dollars.
Answer:
It costs $15 a month to play the video game.
The initial cost is $45.
The y-variable represents the cost in dollars.
The x-variable represents the number of months.
Step-by-step explanation:
If you break the function down, you're going to have:
Total = Monthly Cost + Initial Cost
In this case, 15x is your monthly cost, as you can think of x as the number of months meaning:
15 for the first month (x = 1)30 for the second month (x = 2)45 for the third month (x = 3), and so onOur initial cost is always going to be a set amount, thus our constant, $45.
This leaves y as our total, which makes sense, as it's all alone on one side of the equation, where as all the costs are bunched together on the right side.
Hope this helps!

Reuben L. Goldberg and His Machines
The Artist and His Work
Reuben (Rube) L. Goldberg was an American cartoonist. He is best known for drawing elaborate machines. His drawings showed machines with wheels, gears, handles, pails, and other interesting devices. The machines in Goldberg's drawings were designed to take a simple task and make it complex. The contraptions he drew 80 years ago were so funny that they continue to inspire young scientists and engineers today.
Goldberg's Career
Goldberg's cartoons appeared in several respected New York City newspapers, including the New York Evening Journal and the New York Evening Mail. The cartoonist also wrote a feature film called Soup to Nuts, which was the first film starring the Three Stooges. Goldberg's machines appear in the film.
How to Build a Cause-Effect Machine
Every year students build machines based on Goldberg's designs for school projects, for competitions, or simply for fun. Goldberg's machines operate based on cause and effect. Students and engineers of all ages can learn to build these elaborate cause-effect machines. The key to building one of these machines is to understand how to use gravity and force to push and pull objects along a path. Reading up on these concepts is a good place to start. After that, building the machines is all about having fun. Find a simple task for the machine to do. Then, find a complicated way for the machine to do it.
The Cause-Effect Machine in Popular Culture
Cause-effect machines are incredibly fun to watch. For this reason, they have found their way into Hollywood movies such as Back to the Future and The Goonies. The machines also inspired a board game for kids called Mouse Trap. Clearly, Goldberg's machines have a place in our popular culture.

Explain how you can find the side length of a rectangular prism if you are given the volume and the 2 other measurements. Does this process change if one of the measurements is a fraction?
Answer:
The volume of a rectangular prism can be calculated by the formula:
Volume of a rectangular prism = length * width * heightIf the exercise give us the volume and the two other measurements (width and height), we must simplify the length from the formula showed (remember when a value is multiplying in a side to the equal sign, go to the other side to divide):
(Volume of a rectangular prism) / (width * height) = lengthOr, in other form:
[tex]length=\frac{volume}{width*height}[/tex]At last, the proccess change only a little if one is a fraction, in that case, you should just multiply or divide with that fraction.
Step-by-step explanation:
We're gonna take measurements for the volume, width and height to solve a hypothetical exercise:
Volume = 240 [tex]in^{3}[/tex]Width = 4 inHeight = 12 inWe use the formula in the answer:
[tex]length=\frac{volume}{width*height}[/tex]Replacing the data we obtain:
[tex]length=\frac{240in^{3} }{4 in *12in }[/tex][tex]length=\frac{240in^{3} }{48in^{2} }[/tex][tex]length=[/tex] 5 inchesNow, we're gonna make the a hypothetical exercise where a measurement is a fraction, we can select anyone, in this case will be the width:
Volume = 48 [tex]in^{3}[/tex]Width = 8/3 inHeight = 6 inWe use the same formula and replace again:
[tex]length=\frac{volume}{width*height}[/tex]
[tex]length=\frac{48in^{3} }{\frac{8}{3}in *6 in}[/tex][tex]length=\frac{48in^{3} }{16in^{2} }[/tex][tex]length=[/tex] 3 inchesAs you can see, the process does't change much using fractions, you must only know the correct form to operate these.
