Answer:

Cereal B.

Step-by-step explanation:

To figure out how much it costs per ounce for each cereal, first we need to divide.

Cereal A: $2.25 / 10 = $.225 per ounce

Cereal B: $3.30 / 15 = $.22 per ounce

So, cereal B is less expensive.

A gold, a silver, and a bronze medal are awarded in an Olympic event. In how many possible ways can the medals be awarded for a
grigory [225]

Answer:

The medals can be awarded in 1,320 possible ways.

Step-by-step explanation:

Given that a gold, a silver, and a bronze medal are awarded in an Olympic event, to determine in how many possible ways can the medals be awarded for a 200-meter sprint in which there are 12 runners, the following calculation must be performed:

12 x 11 x 10 = X

12 x 110 = X

1,320 = X

Therefore, the medals can be awarded in 1,320 possible ways.

50 POINTS!! Drag each label to the correct location on the image. Not all labels will be used. The values of a, b, and c in scie
serg [7]

Answer:

\boxed{a*b = 1.60 * 10^2}

\boxed{a/b = 7.53 * 10^{-14}}

\boxed{c/a = 1.59 * 10^{13}}

Step-by-step explanation:

a = 3.47 * 10^{-6}

b = 4.61 * 10^7

c = 5.52*10^7

<u><em>Finding a*b:</em></u>

a*b =( 3.47 * 10^{-6} )*( 4.61 * 10^7)

= (3.47*4.61) * (10^{-6}*10^7)

When bases are same, powers are to be added

= 15.997 * 10^{-6+7}

= 15.997 * 10^1

= 159.97

Rounding it off

=> 1.60 * 10²

<u><em>Finding a/b:</em></u>

=> \frac{3.47*10^{-6}}{4.61*10^7}

Using rule of exponents a^m/a^n = a^{m-n}

=> 0.753 * 10^{-6-7}

=> 7.53*10^{-1}*10^{-13}

=> 7.53 * 10^{-1-13}

=> 7.53 * 10⁻¹⁴

<u><em>Finding c/a:</em></u>

=> \frac{5.52 * 10^7}{3.47*10^{-6}}

=> 1.59 * 10^{7+6}

=> 1.59 * 10¹³

If vectors i+j+2k, i+pj+5k and 5i+3j+4k are linearly dependent, the value of p is what?​
IRINA_888 [86]

Answer:

p = 2 if given vectors must be linearly independent.

Step-by-step explanation:

A linear combination is linearly dependent if and only if there is at least one coefficient equal to zero. If \vec u = (1,1,2), \vec v = (1,p,5) and \vec w = (5,3,4), the linear combination is:

\alpha_{1}\cdot (1,1,2)+\alpha_{2}\cdot (1,p,5)+\alpha_{3}\cdot (5,3,4) =(0,0,0)

In other words, the following system of equations must be satisfied:

\alpha_{1}+\alpha_{2}+5\cdot \alpha_{3}=0 (Eq. 1)

\alpha_{1}+p\cdot \alpha_{2}+3\cdot \alpha_{3}=0 (Eq. 2)

2\cdot \alpha_{1}+5\cdot \alpha_{2}+4\cdot \alpha_{3}=0 (Eq. 3)

By Eq. 1:

\alpha_{1} = -\alpha_{2}-5\cdot \alpha_{3}

Eq. 1 in Eqs. 2-3:

-\alpha_{2}-5\cdot \alpha_{3}+p\cdot \alpha_{2}+3\cdot \alpha_{3}=0

-2\cdot \alpha_{2}-10\cdot \alpha_{3}+5\cdot \alpha_{2}+4\cdot \alpha_{3}=0

(p-1)\cdot \alpha_{2}-2\cdot \alpha_{3}=0 (Eq. 2b)

3\cdot \alpha_{2}-6\cdot \alpha_{3} = 0 (Eq. 3b)

By Eq. 3b:

\alpha_{3} = \frac{1}{2}\cdot \alpha_{2}

Eq. 3b in Eq. 2b:

(p-2)\cdot \alpha_{2} = 0

If p = 2 if given vectors must be linearly independent.
