Answer:
model a: 9 presses
model b: 9 presses
Step-by-step explanation:
let x=model a and y=model b.
If asanji has 28 printing presses, we can say that x+y=18.
If he can print 1260 books in a day, we can say that 80x+60y=1260.
Now, We can solve the system of equation by solving an equation in terms of any variable. You can choose any variable. I chose x. x+y=18, So if we subract y from each side, we get x=18-y. Now, we can substitute that in the other equation. Thus, 80(18-y) +60y=1260. If we continue to solve for y, 1440-80y+60y=1260, 1440-20y=1260, subtract 1440 from each side, which gives you -20y=-180, and divide - 20 and you get y=9. Now, substitute the 9 in the x+y=18 to find x. Thus, x+9=18, and x=9. So, Asanji has 9 press of Model A and 9 presses of Model B.
You are making an audience selection. The first selection narrows your audience of 240,000 by 25% and the next selection narrows that audience 40%. What is the size of your resulting audience?
Answer:
the answer is c. 108,000
Step-by-step explanation:
240,000×25%=60,000
240,000-60,000=180,000
180,000×40%=72,000
180,000-72,000=108,000
your answer is 108,000

Answer:
x = 90
Step-by-step explanation:
A line will ALWAYS equal 180 degrees, so we know that one angle is <90 and we have to find x, which is the other angle of the line.
So, x + 90 = 180
You can either solve the equation for x or you can just subtract 90 from x, which is the easier way.
180 - 90 = 90
So, x = 90

Mojave art club is selling t shirts for a fundraiser. A local company charges $35 to set up the logo and $4.25 per t shirt if x t shirts are printed by the business.
If the art club charged $10 per shirt how many shirts would need to be sold to cover their costs?
function C(x)=35+4.25x/x
Answer:
At least 7 shirts would need to be sold to cover their costs
Step-by-step explanation:
Cost of producing x t-shirts.
The cost of producing x t-shirts is a flat fee of 35 plus 4.25 per t-shirt. So
[tex]C(x) = 35 + 4.25x[/tex]
Earnings of selling x t-shirts:
Charges $10 per t-shirt, so it earns 10 for each t-shirt it sells.
[tex]E(x) = 10x[/tex]
How many shirts would need to be sold to cover their costs?
To cover the costs, we need that the earnings are equal or higher than the costs. So
[tex]E(x) \geq C(x)[/tex]
[tex]10x \geq 35 + 4.25x[/tex]
[tex]5.75x \geq 35[/tex]
[tex]x \geq \frac{35}{5.75}[/tex]
[tex]x \geq 6.09[/tex]
Since we cannot sell a decimal part of a shirt, at least 7 shirts would need to be sold to cover their costs
Hi can somebody pllsss tell me the answer
Answer:
choice 3
Step-by-step explanation:
Answer:
Fourth Option
Step-by-step explanation:
The perimeter of a shape is all sides added. So, if you do 2x + 2x + (x+1) + (x+1), you would get 6x+2. To get the answer to the question, you verify to see which one of the options equal to 6x+2.
First option:
2x(x+1) and 2(2x) + 2(x+1). You find what this equals. 2x(x+1) = 2x^2+2x so we can automatically elimate this one.
Second option:
2x(x+1) and 2x+2x+2x+1. Here again you see 2x(x+1) which equals 2x^2+2x and is not correct so we eliminate this.
Third option:
4x(2x+2) and 2x(x+1) + 2x(x+1). Once more you see 2x(x+1) but added to 2x(x+1) which would basically equal 2x^2+2x *2. Therefore, it's not this one.
Fourth option:
6x+2 and 2x+(x+ 1) +2x + (x+ 1). Now this one looks right because we already got 6x+2 and this is the only option that presents that but also because we initially solved 2x + 2x + (x+1) + (x+1) and this equals 2x+(x+ 1) +2x + (x+ 1).
I guess you don't really have to solve each of them you can kinda see and tell that the last one seems right but if you're not sure you should use the process above.
I hope this helped!

all ratios equivalent to 5:1.
Answer:
10:2, 15:3, 20:4, etc.
Step-by-step explanation:
Well just keep going, they all simplify back to 5:1
The required equivalent ratios are,
[tex]10:2\\15:3\\20:4\\[/tex]
Equivalent Ratios:Equivalent ratios are the ratios that are the same when we compare them. Two or more ratios can be compared with each other to check whether they are equivalent or not.
For example, 1:2 and 2:4 are equivalent ratios.
The given ratio is,
[tex]5:1[/tex]
Now, as we know that we can convert the given ratio into fractions.
[tex]\frac{5}{1}[/tex]
Now, for finding the equivalent ratios multiply the same constant in both the numerator and denominator.
So, the required ratios are,
[tex]\frac{5\times2}{1\times 2} =\frac{10}{2}=10:2\\ \frac{5\times3}{1\times 3} =\frac{15}{3}=15:3\\\frac{5\times4}{1\times 4} =\frac{20}{4}=20:4\\[/tex]
And so, on.
