Answer:

The speed is 2 1/2 miles per hour.

Step-by-step explanation:

To determine the rate, divide the distance by the time taken.

5/8 mile ÷ 1/4 hour

Applying the copy dot flip method:

5/8 * 4/1

Gives us 5/2 miles per hour.

Which simplifies to 2 1/2 miles per hour.

A mattress store sold 1,330 mattresses in one year. If 30% of the mattresses sold were king size mattresses, how many king size
PIT_PIT [12445]

The yearly sales total for mattresses equals 1,330.

The percentage of King size mattresses sold is 30% = 30/100 = 0.3

Now, we need to find the actual sales number using the following formula:

King size mattresses sold = Total mattresses sold in a year * Percentage of King size mattresses sold

King size mattresses sold = 1,330 * 0.3 = 399

King size mattresses sold = 399

P varies inversely with x. If P = 14 when x= 16, find the value of P when x = 21.
tester [12383]

Answer:

Option C. 32/3

Step-by-step explanation:

It is understood that

A relationship between two variables, x and y, signifies inverse variation if it can be represented as either p*x=k or p=k/x

It is also known that

For p=14, x=16

Determine the value of k

k=p*x

By substituting these values

k=(14)*(16)=224

This shows that

The equation equals

p=\frac{224}{x}

Calculate the value of p when x=21

Substitute the given value of x into the equation

p=\frac{224}{21}

Simplify

Divide both the numerator and denominator by 7

p=\frac{32}{3}

Suppose you have two urns with poker chips in them. Urn I contains two red chips and four white chips. Urn II contains three red
Zina [12379]
There are several possible outcomes. The initial composition of the urns is as follows: Urn 1 contains 2 red chips and 4 white chips, totaling 6 chips, whereas Urn 2 has 3 red and 1 white, amounting to 4 chips. When a chip is drawn from the first urn, the probabilities are as follows: for a red chip, it is probability is (2 red from 6 chips = 2/6 = 1/2); for a white chip, it is (4 white from 6 chips = 4/6 = 2/3). After the chip is transferred to the second urn, two scenarios can arise: if the chip drawn from the first urn is white, then Urn 2 will contain 3 red and 2 white chips, making a total of 5 chips, creating a 40% chance for drawing a white chip. Conversely, if a red chip is drawn first, Urn 2 will contain 4 red and 1 white chip, which results in a 20% chance of drawing a white chip. This scenario exemplifies a dependent event, as the outcome hinges on the type of chip drawn first from Urn 1. For the first scenario, the combined probability is (the probability of drawing a white chip from Urn 1) multiplied by (the probability of drawing a white chip from Urn 2), equaling 26.66%. For the second scenario, the probabilities yield a value of 6%.

The value of y at x=-1in the equation 5y=2 is
Zina [12379]

Answer: y = 2/5 --> y = 0.4

Step-by-step explanation:

The equation 5y = 2 represents a horizontal line at y = 2/5.

This means that the y-coordinate holds the value of 2/5 = 0.4 for any x-coordinate.
