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 ,
[tex]Distance = speed \times time[/tex]
Let the distance between Henry and uncle is d,
According to the question ,
[tex]\frac{d}{55} + \frac{d}{45} = 3[/tex]
[tex]\frac{9d + 11d}{495} =3[/tex]
[tex]20d = 3\times 495[/tex]
[tex]d =\frac{3\times495}{20}[/tex]
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
[tex]\rm speed = \dfrac{distance }{time}[/tex]
Let the distance between Henry's uncle from Henry be x.
The time of the trip is during the traveling remains constant. That is
[tex]\rm T = T_1 + T_2\\\\T = \dfrac{x}{v_1} + \dfrac{x}{v_2}[/tex]
The speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather. Then we have
[tex]\rm v_1 = 50 - 5 = 45\\\\v_2 = 50 + 5 = 55[/tex]
Then
[tex]\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}[/tex]
Thus, the distance between Henry's uncle from Henry is 74.25 miles.

The Sharks Aquatic Club recently held a fundraiser to raise money for a local charity. The swimmers received money for each lap that they swam during a one-week period. The three swimmers who raised the most money were Rita, John, and Rodell. Together they swam a total of 2125 laps. John swam three times as many laps as Rita, and Rodell swam 25 more laps than John. How many laps did each swimmer swim?
The number of laps covered by Rita, John, and Rodell will be 300, 900, and 925, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The three swimmers who collected the most cash were Rita (A), John (B), and Rodell (C). Together they swam a sum of 2125 laps. John swam threefold the number of laps as Rita, and Rodell swam 25 additional laps than John.
Then the equations are given as,
A + B + C = 2125 ...1
B = 3A ...2
C = 25 + B ...3
From equations 1, 2, and 3, then we have
B/3 + B + 25 + B = 2125
B/3 + B + B = 2100
(7/3)B = 2100
B = 2100 x 3 / 7
B = 900 laps
Then the value of A will be given as,
A = 900 / 3
A = 300
Then the value of C will be given as,
C = 900 + 25
C = 925
The number of laps covered by Rita, John, and Rodell will be 300, 900, and 925, respectively.

Answer:
a) A = (5, 1), b) A = (1,11)
Step-by-step explanation:
given A is (2,3), question a is represented by a shift of this point 3 units to the right, and 2 units down which means (x,y) → (x +3, y - 2) or T(3,-2)(x,y). (2,3) → (x + 3, y - 2) = (2 + 3, 3 - 2) = (5, 1).
Question b represents a shift of this point one unit to left, and 8 units up which is represented by (x,y) → (x -1 , y + 8) or T(-1,8)(x,y).
(2,3) → (x - 1, y + 8) = (2 - 1 , 3 + 8) = (1, 11).

[tex]y=\frac{3}{2}x-4[/tex]
Step-by-step explanation:
Use the equation of a line: y=mx+b.
First, plug in all of the values that you know. In this case, we are given x, y, and m (the slope).
[tex]y=mx+b\\-4=(\frac{3}{2})(0)+b\\-4=b[/tex]

Answer:
11/12
Step-by-step explanation:
2/3 to 8/12
1/4 to 3/12
8/12+3/12=11/12
Answer:
11/12
Step-by-step explanation:
hi! let's start off by finding the LCM to find a common denominator for these fractions. the LCM of 3 and 4 is 12. so, we can look at what we need to multiply each denominator by to get 12.
3*4 is 12 and 4*3 is 12, so we have to multiply the first fraction by 4/4 (which is equivalent to 1) and we have to multiply the second fraction by 3/3.
this becomes 8/12 and 3/12, which are equivalent to their original forms.
now, we can add these by adding the numerators and keeping the denominators the same.
(8+3)/12

How many times greater was the temperature in Miami (45) than the lowest in San Diego (25)
Answer:
The temperature in Miami is 9/5 times the temperature in San Diego.
Step-by-step explanation:
Ratios
To compare the temperature in Miami (45) with the temperature in San Diego (25), we use the division or ratio between both numbers:
[tex]\displaystyle \frac{45}{25}[/tex]
Simplify the fraction dividing by 5:
[tex]\displaystyle \frac{9}{5}[/tex]
Since the relation between them is 9/5, it means the temperature in Miami is 9/5 times the temperature in San Diego.

Answer:
2, 90
Step-by-step explanation:
Divide 54 by 3 to get how many licks are needed for ONE lollipop. Once you figure how many licks are needed for ONE, you can figure out how many it takes for any amount of lollipops.
54 licks / 3 lollipops = 18 licks / 1 lollipop
Divide 36 by 18 and multiply the quotient by 18 to find the number of lollipops 36 licks takes.
36 licks / 18 licks = 2 lollipops (this is your first answer)
Now multiply 18 by 5 like so: 18 * 5 = 90 (this is your second answer)
