Answer:

16 ounces (nearest ounce)

Step-by-step explanation:

<u>Formula</u>

Volume of a cylinder = πr²h  (where r is the radius and h is the height)

Diameter = 2r  (where r is the radius)

Given:

  • diameter = 7 cm
  • height = 12 cm

⇒ radius = 7 ÷ 2 = 3.5 cm

⇒ Volume of the jar = π · 3.5² · 12 = 147π cm³

If 1 cm³ = 0.034 ounce, then

⇒ Ounces jar can hold = 147π × 0.034

                                      = 15.70168008

                                      = <u>16 ounces</u> (nearest ounce)

Explain why multiplying a fraction by 5/6 results in a value that is less than the original fraction
Ivahew [28]

Answer:

Step-by-step explanation:

(5/6) itself is less than 1 (but greater than 0).  Thus, anything multiplied by (5/6) will result in a smaller-by-magnitude quantity.

For example, (5/6)(3/4) is LESS than 3/4 because 5/6 is greater than zero but less than 1.

1<br> 6 points<br> Solve for x:<br> 3x - 2 = x + 8<br> (Engin+bon.
gizmo_the_mogwai [7]

Answer:

x = 5

Step-by-step explanation:

3x - 2 = x + 8

Subtract x from each side

3x-x - 2 = x-x + 8

2x -2 = 8

Add 2 to each side

2x-2+2 = 8+2

2x = 10

Divide each side by 2

2x/2 =10/2

x = 5

Find the midpoint M of the line segment joining the points S = (-8, 3) and T = (2, -1).
Alex

Step-by-step explanation:

use the midpoint formula

( \frac{xs + xt}{2} \:  \:  \frac{ys + yt}{2} )

substitute into the midpoint formula

( \frac{ - 8 + 2}{2}  \:  \:   \frac{3 + ( - 1)}{2} )

solve the above

(

(3 \:  \: 1)

so the x coordinate if your midpoint is 3

the y coordinate of your midpoint is 1

(3;1)

You can use the pythagoras theorem.

20^2=5^2+x^2

x^2=400-25
x^2=375

x = 19.36

20-19.36=0.64 feet

The answer is 0.64 feet :)
