Answers
Answer:
99.25 milesStep-by-step explanation:
The straight line from the starting point forms a hypotenuse of the right triangle with the legs 75 and 65 miles. Use Pythagorean.
The distance is:
[tex]\sqrt{75^2+65^2} = \sqrt{9850} = 99.25[/tex] miles (rounded)Using Pythagorean theorem
[tex]\\ \rm\longmapsto H^2=P^2+B^2[/tex]
[tex]\\ \rm\longmapsto H^2=75^2+65^2[/tex]
[tex]\\ \rm\longmapsto H^2=9850[/tex]
[tex]\\ \rm\longmapsto H=\sqrt{9850}[/tex]

Hayden had 2 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 3/4 gallons of water left over, about how much water did he use for lettuce?
Answers
Answer:
7/8
Step-by-step explanation:
1/4 + 5/8 = 2/8 + 5/8 = 7/8
= amount used for pepper and tomatoes
2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4
= total amount used
so
7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

An airplane heads in the direction of N25°E at 325 mph. A tailwind is blowing in the direction N40°W at 50 mph. What is the actual velocity of the plane?
A) 315.786 mph
B) 349.084 mph
C) 438.064 mph
D) 121860.018 mph
Answers
In order to fully understand the actual velocity of the airplane bearing, we've carefully drawn out the sketch.
From the image below, by applying the cosine rule to calculate the actual velocity of the plane from the starting point, we have:
b² = a² + c² - 2ac Cos B
where;
a = 50 mph c = 325 mph∠B = 65° + 50° = 115°b² = (50² + 325²) - (2 × 50 × 325 × Cos 115°)
b² = 2500 + 105625 - (32500 × (-0.4226))
b² = 108125 - (-13734.5)
b² = 121859.5
[tex]\mathbf{b =\sqrt{121859.5 }}[/tex]
b = 349.08 mph
Therefore, we can conclude that the actual velocity of the airplane from its starting point is 349.08 mph.

The perimeter of Stephanie’s triangle is half the perimeter of Juan’s triangle. Juan’s triangle is shown. Write a numerical expression to describe the perimeter of Stephanie’s triangle.
Answers
The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]
Let the sides of Juan's triangle be x, y and z. So:
[tex]x = 5 \\ y = 8\\ z = 12[/tex]
The perimeter (J) of Juan's triangle is calculated by adding all sides.
So:
[tex]J =x +y +z[/tex]
This gives:
[tex]J =5 + 8 + 12[/tex]
[tex]J =25[/tex]
From the question, we understand that:
The perimeter (S) of Stephanie's triangle is half that of Juan.
This means that:
[tex]S = \frac 12J[/tex]
Substitute 25 for J
[tex]S = \frac 12 \times 25[/tex]
Hence, the numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]

find x if b is the midpoint of the line AC.

Answer:
[tex]if \: b \: is \: the \: mid \: point \: then \: \\ ab = bc \\ then \: 6x - 6 = 72 \\ 6x = 72 + 6 \\ 6x = 78 \\ x = \frac{78}{6} \\ x = 13 \\ thank \: you[/tex]
This question is simply about division of line segments.
x = 13
We see that point B is the mid point of line AC. This means that;
AB = AC
Now, since AB = 6x - 6 and BC = 72Thus, 6x - 6 = 72
Add 6 to both sides to get;
6x = 78
divide both sides by 6 to get;
x = 13

At the end of a snowstorm, Katherine had 18 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 2.5 inches per hour. Assuming no more snow was falling, how much snow would Katherine have on her lawn 4 hours after the snow began to melt? How much snow would Katherine have on her lawn after t hours of snow melting?
Answers
After 4 hours of snow melting, there would be 8 inches of snow with the rate of 2.5 inches per hour Katherine would have on her lawn and after t hours the snow would be = 18 - 2.5*t inches.
In this question, the amount of snow melted is required to calculate to know the amount of snow on the lawn, can be calculated by:
the melted amount = rate of melting × timeGiven:
The total amount of snow = 18 inches
Rate of melting = 2.5 inches
Time = 4 hours
Solution:
The amount melted needs to be calculated first in order to find left snow, therefore, putting values in the formula mention above,
the melted amount = rate of melting × time
the melted amount = 2.5 × 4 inches
the melted amount = 10 inches
Then the final amount would have on the lawn = starting amount−melted snow
= 18−10 inches
= 8 inches
Part b) Snow after t hours:
Starting amount= 18 inches
Melted snow= inches per hour×t
= 2.5×t
= 2.5t
Final amount = starting amount−melted snow
= 18 -2.5t
Thus, the correct answer is - 8 inches and 18 -2.5t
