4 7/8 + 11 1/2 = 16 3/8
4 + 7/8 + 11 + 1/2
4 + 11 = 15
7/8 + 1/2 = 7/8 + 4/8 = 11/8
11/8 = 1 3/8
15 + 1 + 3/8 = 16 3/8

Cedro bought 10 ounces of Cereal A for $2.25. Then he bought 15 ounces of Cereal B for $3.30. Which cereal is less expensive?
miv72 [106K]

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.

In the calm waters of an inlet, Manon's boat moves with a velocity (speed and direction) vector \vec{b_1} = (3,4) b 1 ​ ​ =(3,4)
andrew-mc [135]

Answer with Step-by-step explanation:

We are given that

b_1=(3,4)

b_2=(1,1)

We have to find the speed of river's current and the direction of current flowing.

b=b_2-b_1=(1,1)-(3,4)=(-2,-3)

Speed of river's current=\mid b\mid

Speed of river's current=\sqrt{(-2)^2+(-3)^2}

Speed of river's current=\sqrt{13} m/s

By using the formula

\mid r\mid =\sqrt{x^2+y^2}

Direction of current flowing,\theta=tan^{-1}(\frac{y}{x})

\theta=tan^{-1}(\frac{-3}{-2})=56.3^{\circ}

The angle lies in third quadrant therefore

\theta=180+56.3=236.3^{\circ}

What percent is the change in the price if the price was $100 and now it is $1250?
Vsevolod [243]

Answer:

  1150%

Step-by-step explanation:

The percentage change is ...

  percentage change = (amount of change)/(original amount) × 100%

  = ((new amount) - (original amount))/(original amount) × 100%

  = ($1250 -$100)/$100 × 100%

  = 1150/100 × 100%

  = 1150%
