r^2=9
\sqrt{r^2} = \sqrt{9}
r=3

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent th
Alla [95]

Answer:

S = \frac{b}{m}

Step-by-step explanation:

Given

Speed = s

Required

Determine the expression for s

The speed is calculated as:

Speed = \frac{Number\ of\ books}{Time}

Substitute S for speed

S= \frac{Number\ of\ books}{Time}

Let the number of books be b and the time be m.

The expression becomes

S = \frac{b}{m}

Hence, the expression for the scenario is:

S = \frac{b}{m}

Aysha has 40 cubes in a bag.
marissa [1.9K]

Given:

Total number of cubes = 40

Red cubes = 18

Blue cubes = 13

Yellow cubes = 9

Aysha adds some more red cubes into the bag.

The probability now that she will take a red cube is 0.5.

To find:

The probability that she will take a yellow cube.

Solution:

Let Aysha adds x red cubes into the bag. Then,

Number of total cubes = 40+x

Number of red cubes = 18+x

Probability of getting a red cube is:

P(Red)=\dfrac{18+x}{40+x}

The probability now that she will take a red cube is 0.5. So,

\dfrac{18+x}{40+x}=0.5

18+x=0.5(40+x)

18+x=20+0.5x

x-0.5x=20-18

0.5x=2

Divide both sides by 0.5.

x=\dfrac{2}{0.5}

x=4

It means Aysha adds 4 more red cubes into the bag.

Now, the total number of cubes int he bag is:

40+4=44

Probability of getting a yellow cube is:

P(Yellow)=\dfrac{\text{Number of yellow cubes}}{\text{Total number of cubes}}

P(Yellow)=\dfrac{9}{44}

Therefore, the required probability is P(Yellow)=\dfrac{9}{44}.
