Answer:

  • About 28 cm³

Explanation:

The shape of a straw may be modeled by a cylinder; thus, use the formula for the volume of a cylinder with length (or height) 25cm and diameter 12mm.

Formula for the volume of a cylinder:

       V=\pi \times (radius)^2\times height

For the given straw:

  • radius = diameter/2 = 12mm /2 = 6mm

  • Convert to cm: 6mm × 1cm/10mm = 0.6cm

  • height: 25cm

Substitute and compute:

         V=\pi \times (0.6cm)^2\times 25cm\approx28.27cm^2\approx28cm^3

You spin the spinner shown below once. Each sector shown has an equal area.
a_sh-v [17]

Answer:  P(not shaded sector) = 0.50

Step-by-step explanation:

Since we have given that

Number of shaded parts = 6

Number of unshaded parts = 6

Total parts = 6+6 = 12

So, Probability of getting not shaded sector is given by

\dfrac{6}{12}\\\\=\dfrac{1}{2}\\\\=0.50

Hence, P(not shaded sector) = 0.50

Novay_Z [31]

Answer: x = 4; x = 5

Step-by-step explanation:

The directions specify to solve by factoring

x^2 - 9x + 20 = 0

To factor, find two numbers that add to -9 and multiply to 20

-5 and -4 work

-5 + (-4) = -9

-5 * -4 = 20

(x - 4)(x - 5) = 0

x = 4, x =5
