an airplane is flying from montreal to vancouver. the wind is blowing from the west at 60km/h. the airplane flies at an airspeed of 750km/h and must stay on a heading of 65 degrees west of north. what heading should the pilot take to compensate for the wind? what is the speed of the airplane relative to the ground?

Answers

Refer to the diagram shown below.

In order for the airplane to maintain a heading of 65° west of north, it actually heads at (65° +x) west of north at a speed of 750 km/h, to compensate for the wind blowing from west t east at 60 km/h.

The actual speed of the airplane relative to the ground is V km/h.

From geometry, obtain the triangle shown.
The speed of 750 km/h is opposite an angle of 155°, and the unknown angle x is opposite the wind speed of 60 km/h.

From the Law of Sines, obtain
[tex] \frac{sin(x)}{60}= \frac{sin(155^{o}}{750} \\ sin(x)= (\frac{60}{750})sin(155^{o})=0.0338[/tex]
[tex]x=sin^{-1}0.0338=1.937^{o}[/tex]

The heading that the pilot should take is 65 + 1.937 = 66.94° west of north.

The third angle of the triangle is 180 - (155 + 1.937) = 23.063°.
Use the Law of Sines to calculate V.
[tex] \frac{V}{sin(23.063^{o})}= \frac{750}{sin(155^{o})} [/tex]
[tex]V=( \frac{sin(23.063)}{sin(155)} )750=695.21\,km/h[/tex]

Answer:
The pilot heads approximately 67° (nearest integer) west of north.
The speed of the airplane relative to ground is 695.2 km/h (nearest tenth)

given that there are eight ounces in a cup and four cups in a quart, which quantity below is equal to 128 ounces

256 ounces 64 ounces 18 cups 4 quarts

Answers

Answer:

4 quarts i had this question on a test and got it right

Step-by-step explanation:

128 ounces is equal to 4 quarts.

To solve this, we need to convert the amount given in ounces to quarts.

Step-by-Step Solution:

There are 8 ounces in a cup.There are 4 cups in a quart.Therefore, there are 8 ounces/cup × 4 cups/quart = 32 ounces in a quart.To find out how many quarts are in 128 ounces, divide 128 by 32: 128 ounces / 32 ounces per quart = 4 quarts.

So, the quantity equal to 128 ounces is 4 quarts.

The other options: 256 ounces and 64 ounces are obviously not equal to 128 ounces since 256≠ 128≠ 64

and, 18 cups =18×8= 144 ounces ≠ 128 ounces.

A man owned 5/8 of an interest in a house. He sold 1/5 of his interest, at a cost for $1000. What is the total value of the house? Explain how u solved it.

Answers

First you would have to find a common denominator with 1/5 and 5/8, which would be 40. So, they would now be 8/40 and 25/40. If 8/40 is $1,000, then you need to figure out how many 8/40 you need to get 40/40. You need 5 8/40, so you multiply $1,000 by 5 to get $5,000, which is the answer.

−5=−8−x What is x? Solve for x

Answers

Hello there!

-5 = -8 -x
First, we need to get x isolated (put on one side of the equation by itself), and then divide by -1 to get rid of the negative sign.
Add 8 to both sides.
-5 + 8 = 3
-8 + 8 = 0
You are left with:
-x = 3
Now, we must divide both sides by -1 to solve for x.
-x / -1 = x
3 / -1 = -3
You are now left with the following solution:
x = -3

The weight of 10 identical samples of a substance is 0.01 pound what is the weight of 10,000 samples

Answers

We use ratios here.

For every 10 samples, the total weight is 0.01 lb.

We write
10 / 0.01.

We want to find the weight of 10,000 samples.

We write
10,000/?

These two ratios must equal each other.

(10 / 0.01) = (10,000 / ?)

If you know how to cross-multiply, then we can do that here.
0.01 * 10000 = 10 * ?
100 = 10 * ?

The unknown value is 10, which is your answer.

Answer:

The weight of 10,000 samples is:

10 pounds.

Step-by-step explanation:

It is given that:

The weight of 10 identical samples of a substance is 0.01 pound.

i.e. 10 samples= 0.01 pound.

Now we are asked to find the weight of 10,000 samples.

Since,

10 samples= 0.01 pound.

1000×10 samples= 1000×0.01 pounds

i.e.

10000 samples= 10 pounds.

Hence, the answer is: 10 pounds.

Determine two pairs of polar coordinates for the point (4, -4) with 0° ≤ θ < 360°.

Answers

A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.

The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,

r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)

Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2

The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°

Hence, the polar coordinate is (4√2, 315°)

(12(0.08)+x(0.2))/(12+x)=0.16 perform indicated multiplication on left side

(0.96+0.2x)/(12+x)=0.16 multiply both sides by (12+x)

0.96+0.2x=1.92+0.16x subtract 0.16x from both sides

0.96+0.04x=1.92 subtract 0.96 from both sides

0.04x=0.96 divide both sides by 0.04

x=24

the lines shown below are perpendicular. if the green line has a slope of 1/7, what is the slope of the red line?

Answers

Answer: it's -7

Step-by-step explanation:

Answer:

Therefore, the slope of the red line must be -7

Step-by-step explanation:

If the two lines are said to be perpendicular each other, then the multiplicative of their slope is -1.

Let "m1" be the slope a line and "m2" be the slope of the perpendicular line.

So, m1*m2 = -1

Here, let's take "m1" be the slope of the green line and "m2" be the slope of the red line.

They said to be perpendicular to each other.

So, m1*m2 = -1

Given: m1 = 1/7

NOw plug in m1 = 1/7 in the above statement, we get

1/7 *m2 = -1

Let's find the value of m2, multiply both sides by the reciprocal of 1/7

The reciprocal of 1/7 is 7.

7*1/7*m2 = -1*7

7/7.m2 = -7

m2 = -7

Therefore, the slope of the red line must be -7

In any case, divide by three: equilateral=same sides, triangle=3 sides

Let x represent one side of equilateral triangle.
Next, we know that the perimeter of the equilateral triangle= side+side+side,so
P=x+x+x with the P=15x^3+33x^5 feet
15x^3+33x^5=3x
Divided both side by 3
(15x^3+33x^5)/3=3x/3

x=x³(5+11x²) feet. As a result, the length of each side is x³(5+11x²) feet. Hope it help!

Starting at home, Jessica traveled uphill to the grocery store for 18 minutes at just 20 mph. She then traveled back home along the same path downhill at a speed of 60 mph.

What is her average speed for the entire trip from home to the grocery store and back?

Answers

The average speed is 40 miles per hour.

Based on the formula [tex]distance = velocity*time[/tex] we can find the distance from the grocery store:

[tex]distance = velocity * time = 20mph * \frac{18}{60}hrs = 6 miles[/tex]

Based on this distance we can find the time it took her to get back using the formula [tex]time = \frac{distance}{velocity}: [/tex]

[tex]time = \frac{distance}{velocity} = \frac{6 miles}{60mph} = \frac{1}{10}hrs = 6 minutes[/tex]

After this you just take the average of Jessica going at 20 mph for 18 minutes and 60 mph for 6 minutes:

[tex]\frac{20mph * 18min + 60mph*6min}{24min} = 30mph[/tex]

C+1/c-2 = 4/7 please show how you got the answer which is 5

Answers

Assuming the equation is (c+1)/(c-2) = 4/7, the answer is actually c = -5

(c+1)/(c-2) = 4/7
7*(c+1) = 4*(c-2) ... cross multiply
7c+7 = 4c-8
7c+7-7 = 4c-8-7 ... subtract 7 from both sides
7c = 4c-15
7c-4c = 4c-15-4c ... subtract 4c from both sides
3c = -15
3c/3 = -15/3 ... divide both sides by 3
c = -5

----------------------------

Check:

(c+1)/(c-2) = 4/7
(-5+1)/(-5-2) = 4/7 ... replace every copy of 'c' with '-5'
(-4)/(-7) = 4/7
4/7 = 4/7 .. true equation; answer checks out

So the answer of c = -5 has been confirmed.

Step-by-step explanation:

Given : the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F as , [tex]F=\frac{9}{5}C+32[/tex]

We have to find the correct formula that solve for C,

Consider the given formula,

[tex]F=\frac{9}{5}C+32[/tex]

We have to find formula for C,

Thus, first subtract 32 both side, we get,

[tex]F-32=\frac{9}{5}C[/tex]

Now, multiply 5 both side, we get,

[tex]5(F-32)={9}C[/tex]

Now , divide both side by 9, we get,

[tex]\frac{5(F-32)}{9}=C[/tex]

Thus, formula that solves for C is [tex]C=\frac{5(F-32)}{9}[/tex]

Thus, option (D) is correct.
