PLS HELP marking brainliest 20-27 show ur work

Mathematics
1 answer:
Ivanshal [37]2 years ago
8 0

Answer:

-7?

Step-by-step explanation:

I mean, is the question 20 - 27 =? Or it's something else? Lol.

20 - 27 = -7, it's very straightforward cannot write it in more detailed way. When we substract a number from another and the first one is smaller the result is a negative number. Imagine someone sells up to 3 apples, you ask him to give you 5. He gives you all 3 of his so he has 0 but you force him to go and get another 2 for you. He lost another 2, so he has less than 0 now. He has -2 apples: 3 - 5 = -2.

Now, I don't know if this is the question or these are set of exercises you must solve and your picture just didn't upload. Let me know if you need help with anything else.

Suppose that for a certain company ​C(x)=35x+300,000 represents the total cost​ function, and ​R(x)=75x represents the total rev
enyata [817]

Answer:

40x - 300,000

7,500

Step-by-step explanation:

profit  = revenue - cost

p(x) = 75x - (35x + 300,000)

p(x) = 40x - 300,000

Break even is when profit is zero

40x - 300,000 = 0

40x = 300,000

x = 7,500

At t=0, a rock is dropped from rest from the top of a building 256 ft high. With what velocity will it strike the ground? What i
Rasek [7]

Answer:

128 ft / second.

Step-by-step explanation:

It's acceleration is due to gravity and is 32 ft s^-2.

To find the velocity when it hits the ground we use the equation of motion

v^2 = u^2 + 2gs    where  u = initial velocity, g = acceleration , s = distance.

v^2 = 0^2 + 2 * 32 * 256

v^2 = 16384

v =  128 ft s^-1.

Please help with 2 Math questions. I dont really understand
lisabon 2012 [21]
For the first problem, the answer is D, because every year, the graph goes down by about $4,500.
For problem two, 
a. It's located in quadrant one because x and y are both positive (I've attached a graph with labeled quadrants for reference)
I'm unsure about b and c but I hope I helped with the others!

What is 21 1/4% expressed as a fraction?
Neporo4naja [7]

Answer:

\frac{17}{80}

Step-by-step explanation:

we have

21\frac{1}{4}\%

Convert mixed number to an improper fraction

21\frac{1}{4}=21+\frac{1}{4}=\frac{21*4+1}{4}=\frac{85}{4}

so

21\frac{1}{4}\%=\frac{85}{4}\%

Convert percent number as a fraction

\frac{85}{4}\%=\frac{85}{4}:100=\frac{85}{4*100}=\frac{85}{400}

Simplify

Divide by 5 both numerator and denominator

\frac{17}{80}
