Emma has 53 marbles she gets some marbles from Fred then she gives 10 marbles to yessir she how has 58 how many does she gets from Fred

Answers

Answer 1
Answer: 53 + x - 10 = 58 (x = marbles Fred gave)
53 + x = 68 (use operations on both sides, subtract 10 from left side and add 10 to right side)
x = 68-53 (switch the placement around)
x = 15
Fred gave her 15 marbles.

Complete the solution of the equation. find the value of y when x equals to 28

x+3y=28

Answers

Answer:

y = 0

Step-by-step explanation:

We are given the following equation and we are to find the value of y when x equals to 28:

Substituting the given value of x in the above equation:

Therefore, y = 0 when x = 28.

Answer:

y=0

Step-by-step explanation:

If x equals 28 then substitute it in the equation, 28+3y=28

Next, subtract 28 from both sides, 3y=0

Now that you have that its simple, y must equal 0

A toy factor paints all of its rubber balls with 2 coats of of latex for durability. How many square centimeters of latex are needed to cover a rubber ball with a circumference of 16π cm?

Answers

Answer:

  • 1 coat: 256π cm² ≈ 804.25 cm²
  • 2 coats: 512π cm² ≈ 1608.50 cm²   (rounds to 1608 cm²)

Step-by-step explanation:

The radius of the ball is ...

  r = C/(2π) = (16π cm)/(2π) = 8 cm

The formula for the area of a sphere is ...

  A = 4πr²

Filling in the value of the radius, we find the area of the ball to be ...

  A = 4π(8 cm)² = 256π cm² ≈ 804.25 cm²

Then 256π or 804.25 is the number of square centimeters needed to cover the given ball with one coat of latex.

If the ball is only considered to be covered when it has two coats of latex, then twice that amount, 512π or 1608.50 square centimeters of latex are required.
