Which of the following values for x and y make the equation 4x+2y+3=19 true?
Aleksandr-060686 [28]

Answer:

x = 3, y = 2

Step-by-step explanation:

Substitute the values of x from each alternative in the previous <em>question</em>, then solve for y. This is depicted below.

  • <em>A. y = -7, x = 5, 4(5) + 2y + 3 = 19</em>
  • <em>B. y = 0 and x = 4, 4(4) + 2y + 3 = 19</em>
  • <em>C. y = 2 and x = 3, 4(3) + 2y + 3 = 1</em>
  • <em>D. y = 4, x = 2, 4(2) + 2y + 3 = 19</em>

Only the third option has a y value that is <em>comparable</em> to the value in the computations, according to the calculations.

As a result, the letter C is the correct response.

What is the volume of a sphere with a diameter of 3.2 m, rounded to the nearest tenth
frez [133]

Answer:

Volume of a sphere = 17.164 m³ (Approx)

Step-by-step explanation:

Given:

Diameter of a sphere = 3.2 m

Radius of a sphere = Diameter / 2 = 3.2 / 2 = 1.6 m

Find:

Volume of a sphere = ?

Computation:

Volume\ of\ a\ sphere =\frac{4}{3}\pi \times r^3 \\\\Volume\ of\ a\ sphere =\frac{4}{3}\times \frac{22}{7}  \times (1.6)^3 \\\\Volume\ of\ a\ sphere =\frac{4}{3}\times \frac{22}{7}  \times 4.096\\\\Volume\ of\ a\ sphere =17.164

Volume of a sphere = 17.164 m³ (Approx)
