A sports ball has a diameter of 27 cm. Find the volume of the ball. cm.) Round your answer to the nearest tenth if necessary.​
Anestetic [448]
To calculate the volume of a sphere you must use the formula
v=4/3pir^3

The radius (r) is half of the diameter
r=13.5

v=4/3pi13.5^3
v=10305.99

Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)

Find the equation of a line perpendicular to 4x−y=2 that contains the point (4,−2). Write the equation in slope-intercept form.
attashe74 [19]

Step-by-step explanation:

4x -y =2

-y = -4x + 2

y = 4x -2

slope = 4

perpendicular slope is negative inverse

so -1/4

y- -2 = -1/4(x - 4)

y+2 = -1/4x +1

y = -1/4x -1

Select all the expressions with a product less than 2/3.
Monica [59]

The expressions with a product less than 2/3 are:

2/3 × 2/3 and 5/6 × 2/3 ⇒ 2nd and 4th

Step-by-step explanation:

Let us revise some fact about the product of two numbers

  • If x is multiplied by y where y > 1, then the product is greater than x (Ex: if x is 3/4 and y is 2, then xy = (3/4)(2) = 3/2 which is greater than 3/4)
  • If x is multiplied by y where 0 < y < 1, then the product is less than x (Ex: if x = 2/5 and y = 1/3, then xy = (2/5)(1/3) = 2/15 which is less than 2/5)

We need to select all the expressions with a product less than 2/3

∵ 4 and 1/8 × 2/3

- 4 and 1/8 means mixed number 4\frac{1}{8}

∵ 4\frac{1}{8} > 1

- That means the product of it and 2/3 will be greater than 2/3

   as the first fact above

∴ 4\frac{1}{8} × \frac{2}{3} > \frac{2}{3}

∵ \frac{2}{3} × \frac{2}{3}

∵ \frac{2}{3} is between 0 and 1

- That means the product of it and 2/3 will be less than 2/3

   as the second fact above

∴ \frac{2}{3} × \frac{2}{3} < \frac{2}{3}

∵ \frac{2}{3} × 2

∵ 2 > 1

- That means the product of it and 2/3 will be greater than 2/3

   as the first fact above

∴ \frac{2}{3} × 2 > \frac{2}{3}

∵ \frac{5}{6} × \frac{2}{3}

∵ \frac{5}{6} is between 0 and 1

- That means the product of it and 2/3 will be less than 2/3

   as the second fact above

∴ \frac{5}{6} × \frac{2}{3} < \frac{2}{3}

The expressions with a product less than 2/3 are:

2/3 × 2/3 and 5/6 × 2/3
