Answer:320

Step-by-step explanation:

2/5 of the students surveyed lisen to country. So to make the percentage fit the total student population, you figure out what your 2/5 is in a percetnage.  That comes out to 40%. so, 40% of 800 is 320.

Answer:

  9t^3 +t^2

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of the sides. The side lengths are represented by the polynomials shown, so the perimeter (P) is their sum:

  P = (4t^3 -5) + (4t^3 -5) + (t^2 +9) + (t^3 -t^2 -11) + (t^2 +12)

Rearranging to group like terms:

  P = (4t^3 +4t^3 +t^3) + (t^2 -t^2 +t^2) + (-5 -5 +9 -11 +12)

  P = 9t^3 +t^2

The perimeter of the figure is represented by the polynomial 9t^3 +t^2.

Which equation or function is linear?
zepelin [54]

9514 1404 393

Answer:

  C.  2y = (2x-1)/4

Step-by-step explanation:

An equation is linear when the exponents of the variables are 1 and the sum of the exponents of the variables in any term is 1.

a) 3xy = 4 . . . . sum of exponents is 1+1=2

b) f(x) = 2/3(1 -x^2) . . . . exponent is 2

c) 2y = (2x -1)/4 . . . . all exponents are 1 (linear)

d) y = 3/(x+1)  ⇒  xy +y = 3 . . . . sum of exponents is 1+1 = 2

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..​
nasty-shy [4]

Answer:

y > 3\cdot x + 5

Step-by-step explanation:

Let A(x,y) = (-2,4) and y = 3\cdot x + 5. Now we evaluate the given function at x = -2:

y = 3\cdot x + 5 (1)

y = 3\cdot (-2)+5

y = -6 +5

y = -1

Which means that y is less than the y-component of A. Therefore, the right answer is y > 3\cdot x + 5.

Solve the equation<br> -2(2x - 4) = 4x <br> Write it step by step. I really need help
Artist 52 [7]

Answer:

x = 1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2(2x−4)=4x

(−2)(2x)+(−2)(−4)=4x(Distribute)

−4x+8=4x

Step 2: Subtract 4x from both sides.

−4x+8−4x=4x−4x

−8x+8=0

Step 3: Subtract 8 from both sides.

−8x+8−8=0−8

−8x=−8

Step 4: Divide both sides by -8.
