A wind blowing in the direction 0o causes an airplane to drift up 15o from its' original heading of 90o. The ground speed is 336km/hr. Find the airspeed of the plane
Answer:
324.6 km/hr
Step-by-step explanation:
Since the plane drifts up 15° from its original heading of 90°, it is at a bearing of 90° - 15° = 75°.
Now, since its ground speed is 336 km/hr, its air speed, v is the horizontal component of its ground speed since the wind is blowing in the 0° direction. So, v = (336 km/hr)sin75°
= 324.55 km/hr
≅ 324.6 km/hr

Answer: t = 18.8 years
Step-by-step explanation: The modeled function is an exponential function:
[tex]P(t)=78,125e^{0.025t}[/tex]
which is farmland worth along time.
To determine when the farmland will be worth $125,000:
[tex]125,000=78,125e^{0.025t}[/tex]
[tex]e^{0.025t}=\frac{125,000}{78,125}[/tex]
[tex]e^{0.025t}=1.6[/tex]
Apply natural logarithm:
[tex]ln(e^{0.025t})=ln(1.6)[/tex]
And then, power rule:
[tex]0.025t=ln(1.6)[/tex]
[tex]t=\frac{ln(1.6)}{0.025}[/tex]
t ≈ [tex]\frac{0.47}{0.025}[/tex]
t ≈ 18.8
After 18.8 years, the farmland will reach market value of $125,000.

The hypotenuse of a triangle is 37 millimeters long. One of the legs is 24.5 millimeters long. What is the measure of the missing leg? Round to the nearest tenth, if necessary.
Answer: 27.7 millimeters
Step-by-step explanation:
Let the missing leg be represented by x.
We will use Pythagoras formula to solve this. The measure of the missing leg will be:
x² = 37² - 24.5²
x² = 1369 - 600.25
x² = 768.75
x = ✓768.75
x = 27.7
The missing leg is 27.7 millimeter

You want to estimate how many fish there are in a pond. Suppose you cature 140 fish, tag them, and throw them back into the pond. After a couple of days, you go back to the pond and capture 420 fish, of which 28 are tagged.
Answer:
2,100
Step-by-step explanation:
Calculation to Estimate the number of fish in the pond.
Estimated Number of fish=420 fish*140 fish/28
Estimated Number of fish=58,800/28
Estimated Number of fish=2,100
Therefore the Estimated number of fish in the pond will be 2,100
The total number of fish in the pond is 2100
Let y represent the total fish in the pond.
Data obtained from the question Tagged fish in pond = 140Captured fish = 420Captured tagged fish = 28Total fish = y =?The estimated fish in pond can be obtained as follow:
Tagged in pond / Total in pond = captured tagged fish / Captured fish
140 / y = 28 / 420
Cross multiply
y × 28 = 140 × 420
y × 28 = 58800
Divide both side by 28
y = 58800 / 28
y = 2100
Thus, the estimated fish in the pond is 2100

Step-by-step explanation:
2x + 4y = -4 ------------------------(1)
3x + 5y = -3 ------------------------(2)
Multiply Eq. (1) by 3
3(2x + 4y) = -4 * 3
6x + 12y = -12 ---------------------(3)
Multiply Eq. (2) by 2
2(3x + 5y) = -3 * 2
6x + 10y = -6 ---------------------(4)
Subtract Eq. (4) from (3)
6x + 12y - ( 6x + 10y ) = -12 - (-6)
6x + 12y - 6x - 10y = -12 + 6
12y - 10y = -6
2y = -6
Divide 2 to both sides
y = -6 / 2
y = -3
Put y = -3 in Eq. (1)
2x + 4(-3) = -5
2x - 12 = -5
Add 12 to both sides
2x = -5 + 12
2x = 7
Divide 2 to both sides
x = 7 / 2
So,
x = 7 / 2 , y = -3

The length of a rectangle is one more than twice its width. If its perimeter is 20 inches, what is its length and width?
Answer:
Let length be L
Width be W
L=1+2W
Perimeter(p) of rectangle is
P=2L+2W
But L = 1+ 2W and p= 20
:. 20 =2(1+2W) +2W
20=2+4W+2W
18=6W
Divide both sides by 6
W =3
2W+1=L
6+1=L
L=7
Hence, length and width are 7in and 3in respectively

Answer:
A and B
Step-by-step explanation:
Speed is the change in distance divided by the change in time. That is, it is the slope of the distance vs. time curve. A steeper slope corresponds to a greater speed.
Between A and B, the slope is (30-0)/(1-0) meters/time-unit = 30 m/u.
Between B and C, the slope is (30-10)/(4-1) = 20/3 = 6 2/3 m/u.
Between C and D, the slope is 0.
Between D and F, the slope is (50-10)/(10-6) = 40/4 = 10 m/u.
The greatest slope is between A and B.
The object has the greatest speed between points A and B.
