Answer:

The plane travels at a speed of 66 miles per hour without wind.

Step-by-step explanation:

Tyler trip has to stage, the first one where he went against the wind and the second where he returned with the wind. We know that the wind speed is 6 mph, if we attribute the variable "x" to the speed of the plane without wind, then on the first stage of its trip the total speed relative to the ground was "x - 6", while on the return trip it was "x + 6". We also know that the distance between the trips was the same 4320 miles, but the second stage was 12 hours faster. We will use the average speed formula to solve this problem, this is shown below:

[tex]\text{speed} = \frac{\text{distance}}{\text{time}}[/tex]

For the first trip the speed was:

[tex]x - 6 = \frac{4320}{\text{time}_1}\\\\\text{time}_1 = \frac{4320}{x - 6}[/tex]

For the second trip the speed was:

[tex]x + 6 = \frac{4320}{\text{time}_2}\\\\\text{time}_2 = \frac{4320}{x + 6}[/tex]

Since the time for the second trip was 12 hours less, then if we add 12 to the second equation it should be equal to the first, so:

[tex]time_2 + 12 = time_1[/tex]

[tex]\frac{4320}{x + 6} +12 = \frac{4320}{x - 6}\\\frac{4320}{x+ 6} - \frac{4320}{x - 6} = -12\\\frac{4320*(x - 6) - 4320*(x + 6)}{x^2 - 36} = -12\\4320*x - 25920 - 4320*x - 25920 = -12*x^2+ 432\\-51840 = -12*x^2 +432\\12*x^2 =51840 + 432\\x^2 = \frac{52272}{12}\\x^2 = 4356\\x = 66[/tex]

The plane travels at a speed of 66 miles per hour.

Answer:

[ 11 - 10 ] / 10 x 100%

= 1 /10 x 100%

= 10%

Only 10% longer

Answer:

Let the first equation be x + y = 10

x = 10 -y

2nd equation will be 1x + 1.2y = 11

Substituting in 2nd equation

(10 - y) + 1.2y = 11

10 - y + 1.2y = 11

.2y = 1

y = 5

If y = 5, x = 5: coz x + y = 10

She have buy 5 stamps of each $1 stamps and  5 stamps of each $1.20 stamps.

A linear equation is an equation that has the variable of the highest power of 1.

The standard form of a linear equation is of the form Ax + B = 0.

Let the first equation be;  

x + y = 10

x = 10 -y

2nd equation will be,

1x + 1.2y = 11

Substituting in 2nd equation;

(10 - y) + 1.2y = 11

10 - y + 1.2y = 11

0.2y = 1

y = 5

If y = 5, x = 5:

x + y = 10

Hence, She have buy 5 stamps of each $1 stamps and  5 stamps of

each $1.20 stamps.

Answer:

500 mg

Step-by-step explanation:

amount of dextrose in  35 ounce Pedialyte = 2500 mg

dividing LHS and RHS by 35

amount of dextrose in  35/35 ounce Pedialyte = 2500 /35 mg = 500/7 mg

Thus,

amount of dextrose in  1 ounce Pedialyte = 500 /7 mg

since we have to find amount of dextrose in  7 ounce Pedialyte

we multiply LHS and RHS by 7

Thus,

amount of dextrose in  1 *7 ounce Pedialyte = 500 /7 * 7 mg = 500 mg

amount of dextrose in  7 ounce Pedialyte = 500 mg

Thus, As child consumed 7 ounces of Pedialyte, He consumed 500 mg of dextrose.

Answer:

P(Take the bus | Sophomore) = 0.83

Step-by-step explanation:

For a conditional probability (As given in the example),

P(A|B) is read as,

"The probability of event A occurring given that event B has occurred"

Here event A = Sophomore take a bus

Event B (occurred) = (Drive to school + Take the bus + Walk)

Therefore, P(Take a bus | Sophomore) = [tex]\frac{25}{(2+25+3)}[/tex]

                                                                = [tex]\frac{25}{30}[/tex]

                                                                = 0.833

                                                                ≈ 0.83

P(Take the bus | Sophomore) = 0.83 will be the answer.

Answer:

D

Step-by-step explanation:

D is the only answer with the correct distance formula format and the correct numbers inside the parentheses

Answer:

Her average speed is 45 mph

Step-by-step explanation:

Let the average speed be x mph

Time taken complete the journey = distance/ average speed

Time = 300/x

Now , at 9 mph less, she could have only traveled 240 miles in same time

At 9 mph less, the average speed is x-9

so the time would be 240/x-9

since the time is same as before;

300/x = 240/x-9

Divide both sides by 60

5/x = 4/x-9

Cross multiply

5(x-9) = 4(x)

5x - 45 = 4x

5x -4x = 45

x = 45 mph

Answer:

Step-by-step explanation:

For us,

P = 728,

r = .044,

e is Euler's number (a constant), and

t is 16. Filling in:

[tex]V=728e^{(.044)(16)}[/tex] and

[tex]V=728e^{(.704)}[/tex] and

V = 728(2.02182385) so

V = $1471.89

A person places $728 in an investment account earning an annual rate of 4.4%, compounded continuously. The value of the account in t years is $1471.89.

We have given that,

P = 728,

r = 0.044,

e is Euler's number (a constant), and

t = 16.

The formula of the account in t years is,

[tex]V = Pe^{rt}[/tex]

Use the given value in the above formula,

V = 728(2.02182385)

Therefore we get,

V = $1471.89

Therefore, the value of the account in t years is $1471.89.

[tex]\text{As } x \to \infty, y \to \infty,$and as x \to -\infty, y \to \infty[/tex]

Step-by-step explanation:

Given the polynomial function: [tex]h(x)=-x^3+x^4-2x+1[/tex]

To examine its end behavior, we create a table of values that we can then examine.

[tex]\left|\begin{array}{c|c}x&h(x)\\--&--\\-4&329\\-3&115\\-2&29\\-1&5\\0&1\\1&-1\\2&5\\3&49\\4&185\end{array}\right|[/tex]

From the table, we see a repeating pattern of positive values of h(x) with h(1)=-1 being an axis of symmetry.

Therefore, as:
