A pilot was scheduled to depart at 4:00 pm, but due to air traffic, her departure has been delayed by 15 minutes. Air traffic co

AlladinOne [14]

Answer:

$y = \frac{x}{2}+15$ will be the equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

Step-by-step explanation:

Let x represent the time, in minutes, of her original flight plan.

Let y represents the time, in minutes, of her new flight plan.

The time of Original flight schedule = 4:00 pm

The number of minutes delayed by Original flight = 15 minutes

As the new flight plan is two times faster than original flight plan.

So, the equation of new flight plan will be:

$y = \frac{1}{2}x$

$y = \frac{x}{2}$

But, the original flight plan was delayed by 15 minutes. Hence, the equation to predict the number of minutes after 4:00 pm she will arrive at her destination will become:

$y = \frac{x}{2}+15$

So, $y = \frac{x}{2}+15$ will be the equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

Dorothy is using fabric to cover a photo album the width of the fabric is 5/8 of a yard the area of the fabric is 5/16 square ya

saul85 [17]

For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

$A = a * b$

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

According to the problem data we have to:

$b =\frac {5}{8} \yard\\A = \frac {5} {16} \ yards ^ 2$

Substituting:

$\frac {5} {16} = a * \frac {5} {8}$

We clear "a":

$a = \frac {\frac {5} {16}} {\frac {5} {8}}\\a = \frac {5 * 8} {16 * 5}\\a = \frac {8} {16}\\a = \frac {1} {2}$

Thus, the length of the fabric is $\frac {1} {2} yards.$

ANswer:

The length of the fabric is $\frac {1} {2} yards.$

During a free fall Swati was accelerating at -9.8m/s^2. After 120 seconds how far did she travel? Use the formula =1/2 * t^2 to

jarptica [38.1K]

Answer:

She traveled 70560 m.

Step-by-step explanation:

Given :

Acceleration (g) = $-9.8m/s^{2}$

Time : 120 seconds .

To Find : Distance traveled

Solution:

Since we are given that there is a free fall .

So, we will use the formula: $d=\frac{1}{2} gt^{2}$

Now put the given values in the formula :

⇒ $d=\frac{1}{2}*(-9.8)*(120)^{2}$

⇒ $d=\frac{1}{2}*(-9.8)*14400$

⇒ $d=\frac{-141120}{2}$

⇒ $d=-70560$

Negative sign shows the direction only.

Hence she traveled 70560 m.

The initial value of a stock is $2500. The value of the stock is expected to grow at an annual rate of 4%. Let x represent the n

vekshin1

Answer:

y = ($2500)(1.04)^x

Step-by-step explanation:

The initial value = $2500

The value of the stock is expected to grow at the rate of 4%

Let x represent the number of years since the stock was made available for purchase.

Let y represent the value of the stock x years later.

y1 = amount of money after one year.

y1 = $2500 (100% + 4%)

y1 = $2500 (104%)

y1 = $2500(1.04)

y2 = amount of money after two years

y2 = y1 (100% + 4%)

y2 = y1 (104%)

y2 = y1(1.04)

y2 = $2500(1.04)(1.04)

y2 = $2500(1.04)^2

This will give a pattern

y5 = $2500(1.04)^5

After x years the model of the equation will be y = ($2500)(1.04)^x

Find the value of x and y

Nesterboy [21]

Step-by-step explanation:

step 1. break into 2 shapes: a rectangle of sides 3 and 4. a triangle of sides (x - 3), 4, and y.

step 2. y = 4sqrt(2) (definition of a 45° triangle)

step 3. note: sqrt is the square root.

step 4. x - 3 = 4 (definition of a 45° triangle)

step 5. x = 7 (add 3 to both sides).
