Have you learned PEMDAS? (Parenthesis, exponents, multiplication, division, addition, subtraction). That is what I am going to do here.
The first parenthesis, let's solve. 7*10=70-5=65
The second parentheisis: I am assuming the negative sign is a typo, and this answer will be off if it is not. Sorry. 5*10=50
65*50=3250
I hope this helps, and let me know if you need further assistance.
3 24/99 is the mixed number
321/99 is the fraction
Answer:The equation relating I, r, and k is I =K/r²
Step-by-step explanation:
The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as
I ∝ 1/r²
Introducing the constant of proportionality, K we have that
I =K x 1/r²
Therefore , the equation relating I, r, and k is I =K/r²
Answer:
im think x = 9
Step-by-step explanation:
The x intercept is -3 so the point (-3,0) is on the line. This point is on the horizontal x axis. The x intercept is always in the form (NUMBER,0) where you replace "NUMBER" with any number you want.
The y intercept is -4 so we know that (0,-4) is also on the line. This is on the vertical y axis. The y intercept is always in the form (0,NUMBER)
Use the slope formula to find the slope of the line through the points (-3,0) and (0,-4)
m = (y2-y1)/(x2-x1)
m = (-4-0)/(0-(-3))
m = (-4-0)/(0+3)
m = -4/3
The answer is choice B: -4/3
I have a feeling you mixed up x and y somehow when you got -3/4
