Answer:
Distance between Henry and his uncle is 74.25km.
Step-by-step explanation:
Speed of Hawk with wind = 50+5
=55km/hr
Speed of Hawk against wind = 50-5
=45km/hr
we know that ,
\(Distance = speed \times time\)
Let the distance between Henry and uncle is d,
According to the question ,
\(\frac{d}{55} + \frac{d}{45} = 3\)
\(\frac{9d + 11d}{495} =3\)
\(20d = 3\times 495\)
\(d =\frac{3\times495}{20}\)
d= 74.25km
Hence , the answer is 74.25km
The relation between speed, time, and distance is used. Then the distance between Henry's uncle from Henry is 74.25 miles.
What is speed?The distance covered in an hour is called speed. it is a scalar quantity.
What is relative speed?The concept of relative speed is used when two or more bodies moving with some speed are considered.
Henry sends his hawk with a message to his uncle.
The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip.
We know the relation
\(\rm speed = \dfrac{distance }{time}\)
Let the distance between Henry's uncle from Henry be x.
The time of the trip is during the traveling remains constant. That is
\(\rm T = T_1 + T_2\\\\T = \dfrac{x}{v_1} + \dfrac{x}{v_2}\)
The speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather. Then we have
\(\rm v_1 = 50 - 5 = 45\\\\v_2 = 50 + 5 = 55\)
Then
\(\begin{aligned} \rm \dfrac{x}{45} + \dfrac{x}{55} &= 3\\\\\rm \dfrac{9x + 11x }{495} &= 3\\\\\rm 9x + 11x &= 1485\\\\\rm 20x &= 1485\\\\\rm x &= 74.25 \end{aligned}\)
Thus, the distance between Henry's uncle from Henry is 74.25 miles.

Find the greatest common factor. 5x^2a+5xa^2
The greatest common factor of the expression 5x²a + 5xa² is 5xa
How to find greatest common factor of 5x²a + 5xa²?To find the greatest common factor (GCF) of the expression 5x²a + 5xa², we need to find the greatest term that can divide into both terms in the expression.
In this case, the GCF is 5xa, as it can divide into both 5x²a and 5xa².
We can check this by dividing both terms with 5xa:
5x²a + 5xa² = (5xa)(x) + (5xa)(a) = 5xa (x + a)
Thus, the GCF of 5x²a + 5xa² is 5xa.

The length of ML in the line segment is 35 units.
How to find the line segment ML?The figure below has the following length as follows:
LN = 79 units
Let's find ML in the line segment as follows:
LM + MN = LN
Hence,
LM = 5y - 5
MN = 4y + 12
Therefore,
LN = 5y - 5 + 4y + 12
79 = 5y - 5 + 4y + 12
79 = 9y + 7
79 - 7 = 9y
72 = 9y
divide both sides by 9
y = 72 / 9

On a Cartesian coordinate plane, points $(2,1)$ and $(3, 4)$ are adjacent points on a square. What is the area of the square?
Hey there! :)
Answer:
A = 10 units².
Step-by-step explanation:
To solve this, we need to find the distance between the two points to derive the side-lengths of the square. Use the distance formula:
\(d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\)
Plug in points into the formula to find the distance:
\(d = \sqrt{(3 - 2)^2 + (4-1)^2}\)
Simplify:
\(d = \sqrt{(1)^2 + (3)^2}\)
\(d = \sqrt{(1) + (9)}\)
\(d = \sqrt{10}\)
Find the area of the square using the formula A = s² where s = √10:
A = (√10)²

what is the volume of the rectangular prism ?
Answer:
180 \(cm^2\)
Step-by-step explanation:
L x W x H
6 x 5 x 6
180
Answer: 180 cubic centimeters
Step-by-step explanation:
Each little blue cube measures 1 cm in each direction - width, height, and depth.
The volume of the whole figure is just the volume of all the little cubes, added up.
The block of cubes is 5 cubes wide and has a depth of 6 cubes. So each horizontal layer is 5 * 6 = 30 cubes, total.
The block of cubes is 6 layers deep, so we have 6 layers of 30 cubes each = 6 * (30 cubes) = 180 cubes in all.
Each cube is 1 cubic centimeter (abbreviated 1 cc), so 180 of them have a combined volume of 180 cc.
A shorter way to say all this is to say that V = width * depth * height =
= 5 cm * 6 cm * 6 cm = (5)(6)(6) cm³ = 180 cubic centimeters

The actual distance that is represented by 30 inches on the map is 225 miles.
What is proportion statement?
Simply stating that two ratios are equal is what a proportion is. There are two methods to write it: either using two equal fractions, a/b = c/d, or by using a colon, a:b = c:d.
Given that, a map's scale indicates that 2 inches correspond to 15 miles.
Therefore the scale factor is 15:2.
Assume a proportional statement:
a:b = c:d
Let c:d = 15:2 and b = 30
a:30 = 15:2
Rewrite the ratio as a fraction:
a/30 = 15/2
Multiply both sides by 30
a = (15/2) × 30

write an equation, g(x), for the transformations of the parent function, f(x) =x , when it is reflected across the y-axis and translated down 5 units
Answer:
\(g(x)=-x-5\)
Step-by-step explanation:
if we reflect across the y-axis, the y-value is just being negated, or in other words from positive -> negative or negative -> positive depending on what the initial y-value was.
So if we have the function \(f(x)=x\), then we just negate the x, since the x represents the y-value.
This gives us: \(g(x)=-x\)
Now to translate 5 units down, the y-value is decreasing by 5 units, and since the -x represents the y-value, we just subtract 5 from it to get
\(g(x)=-x-5\)

The region in the first quadrant bounded by y=x^2/5 and y=1
The area of the curve in the first quadrant is A = 2/7 units²
Given data ,
Let the region described is bounded by the curves y = x^(2/5) and y = 1 be in the first quadrant
Now , the point of intersection of these two curves is given by
x^(2/5) = 1
x = 1^5
So the two curves intersect at x = 1
Now , the area of the curve is given by y = x^(2/5) is the lower curve and y = 1 is the upper curve in the given interval [0, 1]
And , the , integral is used to find the area
∫[from 0 to 1] (1 - x^(2/5)) dx
∫(1 - x^(2/5)) dx = x - (5/7)x^(7/5) + C
Evaluated from 0 to 1, we get:
[(1 - (5/7)(1^(7/5))) - (0 - (5/7)(0^(7/5)))]
Simplifying further, we get:
