Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h
a recipe uses 1 1/4 cups of milk to make 10 servings. if the same amount of milk is used for each serving how mant servings can be made using one gallon.
Answer:
I believe its 36
Step-by-step explanation:
so what i id is a took apart the answer, if 1 1/4 if 10 cups the 1/4 1/4 1/4 1/4 1/4 would also be 10 cups, so now i know that 1/4 = 2 servings
eso i took 3. 1/4 and that gave me 6 and now add the previous which is 10 so its 16 and i have 2 cups left
from here i knew 1 cup and 1/4 is 10 so subtract 1/4 which is -2 servings and you have 8 and 8+8 is 16 so
then i added
16+16= 36
which leads to my final answer of 36
Im so sorry if im wronge but if its right please give brainlest

so for translation when it says to move up 6 how do I solve that (ex. -6, -10)
Answer:
Well, the y axis is the up and down line of the graph. Therefore, if the translation says move up six, simply add six to the y axis (ex. -6, -10 move up six: -6, -4)! super simple, right? hope this helps!

Suppose on an Icelandic sheep farm, there was a sheep pen next to a barn. If the length of the pen is 16 meters and the width is 9 meters, what is the area of the sheep pen?
Answer:
A = 144 m²
Step-by-step explanation:
Given that,
The length of the pen, l = 16 m
The breadth of the pen, b = 9 m
We need to find the area of the sheep pan. We know that the area of the rectangular shape is given by :
A = lb
Substituting all the values,
A = 16 m × 9 m
= 144 m²
So, the area of the sheep pen is 144 m².

Students collected data and created an equation to model the spread of a winter cold among the students, teachers, and other staff. They decided this was best represented by the exponential function C(d) = 1*3d where d is the time in days since the cold began to spread.
How many people initially had the cold? _______ people
How many people would have the cold after 2 days? ______ people
Answer:
0 People initially had the cold.
6 People will have it after 2 days.
Step-by-step explanation:
To find out how many people had it initially, plug 0 in for x (implying 0 days later.)
C= 1*3(0)
C= 1*0
C=0
Nobody had the cold initially.
To find out how many people had it after 2 days, plug 2 in for x. (implying 2 days later.)
C= 1*3(2)
C= 1*6
C=6
Therefore 6 people had the cold after 2 days.

(i) What values of x and y will make 3x - 2y equal zero?
(ii) Work out the greatest possible value of 3x - 2y.
(iii) Work out the least possible value of 3x – 2y.
b) Find the value of 5(a – 4b) when a = -7 and b = 1
Answer:
a) i) The equation is satisfies of the values x = 6 and y=9
ii) The greatest possible value of 3x-2y is 20
iii) The least possible value of 3x – 2y is 2 and '0'
b)
The value of 5(a – 4b) = -55
Step-by-step explanation:
Given x and y are two numbers taken from the list below
5 6 7 8 9 10
i)
I will choose x = 6 and y = 9
3x - 2y = 3 (6) - 2(9) = 18 - 18 = 0
The equation is satisfies of the values x = 6 and y=9
ii)
we will choose x =10 and y = 5
3x - 2y = 3(10) - 2(5) = 30 -10 =20
The greatest possible value = 20
iii)
we will choose x =6 and y =8
3x - 2y = 3(6) -2(8) = 18-16 =2
we will choose x =6 and y =9
3x - 2y = 3 (6) - 2(9) = 18 - 18 = 0
b)
Given value of 5(a – 4b)
substitute a = -7 and b = 1
5(a – 4b) = 5(-7-4(1)) = 5 (-11) = -55

Step-by-step explanation:
Braden wants to compare the types of ducks in two nearby ponds. He collected two samples using the following
criteria. For sample 1, he counted the types of ducks on Walden Pond from 6 A.M. to 9 A.M. For sample 2, he counted
the number of Mallard ducks that were on Brook's Pond from 12 P.M to 3 P.M.
What would improve Braden's plan? Select three options.
Braden should sample the ducks on each pond at the same time of day because animals are active at different
times
Braden should sample twice at each pond if he wants to make sure each sample is representative of the
population
Braden should count more than Mallard ducks on Brook's Pond if he wants to compare the types of ducks on each
pond
Braden should only count Mallard ducks on Walden Pond so he counts the same types of ducks as he does at
Brook's pond.
Braden should include herons and geese in his samples because they also like ponds.
Answer:
a then b then c
Braden should sample the ducks on each pond at the same time of day because animals are active at different times.
Braden should sample twice at each pond if he wants to make sure each sample is representative of the population.

Explanation:
Using the pythangorean theorem
[a² + b² = c²], we can solve enough sides to find the proportion because both triangles are right triangles or have a 90° right angle.
Given the lengths of side a and c (the hypotenuse), we can rearrange the pythangorean theorem to solve for b.
a² + b² = c² → a² – a² + b² = c² – a² →
b² = c² – a² → b = √(c² – a²).
We are also given the hypotenuse or the side c of both triangle which are 5 to 7, which is the proportion between the triangles. We also know they are similar because they have one congruent angle and a right angle, thus the third angle must be the same. Therefore the bigger triangle has sides that are 7/5 longer than the smaller triangle. So b of the smaller triangle = √(5² – 4²) = √(25 – 16) = √9 = 3.
Now we know the sides of the smaller triangle:
a = 3
b = 4
c = 5
______
Now the only thing we have to do is match the corresponding sides, and multiply by 7/5.
This means that the sides of the bigger triangle are:
a = 3 × 7/5 = 21/5 = 4.2
b = 4 × 7/5 = 28/5 = 5.6
c = 5 × 7/5 = 7
______________
Each angle corresponds to the side opposite or across from it. Since side a is across from the congruent pair of angles we are given, the a of the bigger triangle must be x which means that x = a = 4.2.

Answer:
[tex] \boxed { - 4}[/tex]
Step-by-step explanation:
Substitute y = x-4 in the first equation.
[tex]3x - 2(x - 4) = 4[/tex]
Distribute -2 in the expression.
[tex]3x - 2x + 8 = 4 \\ x = 4 - 8 \\ x = - 4[/tex]
Because we only want to find the value of x.
Therefore the answer is -4.

how many solutions does this have? x+2y=3 x-y=6
Answer:
x = 5 , y = -1
Step-by-step explanation:
x + 2y = 3........(equation 1)
x - y = 6..........(equation 2)
make x the subject of the formula in (equation 1)
x = 3 - 2y
substitute for x in (equation 2)
3x - y = 6
(3- 2y) - y = 6
3 - 2y - y = 6
3 - 3y = 6
-3y = 6 - 3
[tex] \frac{ - 3y}{ - 3} = \frac{3}{ - 3} [/tex]
[tex]y = - 1[/tex]
substitute for y in (equation 1)
x = 3 - 2y
[tex] \times = 3 - 2( - 1)[/tex]
x = 5
Answer:
Uhhh I'll try my best.
The answer to your question is
I’ll do x.
x+2y-2y = 3-2y
(Simplify) x = 3-2y
x-y+y = 6+y
(Simplify) x = 6+y
(Set them equal to each other)
3-2y = 6+y
3-2y-6 = 6+y+2y
-3 = 3y
y = -1
x =

Visit this online dictionary and search for the definition of justice. Which part of speech is the word justice? Which definition best matches the definition given by the online dictionary?
Answer:
noun and fairness
Step-by-step explanation:
Giving each person what they deserve, or, in more formal terms, their due, is what is meant by justice. Today, the terms justice and fairness are frequently used interchangeably because of their close relationship. However, there have also been more definite interpretations of the two names.
Justice is noun part of speech.
What do you mean by Speech?Speech is the ability to articulately express ideas and thoughts through vocal sounds. It is also the act of doing so.
Justice, in its broadest sense, is the idea that people should get what they deserve. However, there are many different fields and viewpoints that have an impact on what is considered to be "deserving," including those that focus on morality as it relates to ethics, reason, law, religion, equity, and fairness. The state will occasionally make an effort to improve justice by running courts and upholding their decisions.
Therefore, Justice means fair treatment and it is noun part of speech.
