Hey mate!
Using Unitary Method, we get :
2 people -> 5 hours
1 person -> 5/2 = 2.5 hours
3 people -> 2.5 hours * 3 peoples
-> 7.5 hours
-> 7.5 * 60 = 450 mins.
I am always glad to help :)
Answer:
3 people can plow a field in 450 minutes.
Step-by-step explanation:
This is a rate/ratio problem, so we have to make sure it's fully simplified.
First, you already know the ratio is 2 people can plow a field in 5 hours, so 2:5.
But that's not the unit rate.
To find the unit rate, you find how much an individual by itself can do their work, and divide numerator by denominator.
In this case, you do 5/2: which is 2.5.
It take's 2.5 hours for one person. Now you multiply by 3 people to get the ratio; since you already found the rate.
2.5x3 is 7.5, and that's in hours. 1 hour is 60 minutes, to find 7 hours, you do 60x7 and get 420 minutes. You add 30 minutes from the remaining half hour.
that results in 450 minutes.
3 people can plow a field in 450 minutes.

Apothem = (the answer is a sqaure root)
Answer:
[tex]\sqrt{20}[/tex]
Step-by-step explanation:
To find the Apothem of a shape, we need to find how long the distance is from a vertex to the center of the shape.
We can see that they've already showed us how to do it: We need to find the length of the hypotenuse of the red triangle.
To do this, we can use the Pythagorean Theorem, which states that [tex]a^2 + b^2 = c^2[/tex].
We know that a is going to be half of 4, which is 2. We also know that b is going to be 4, so we can substitute inside the equation.
[tex]2^2 + 4^2 = c^2\\\\4 + 16 = c^2\\\\20=c^2\\\\c=\sqrt{20}[/tex]

f(x)=x^2+4x-6 a) f(x) can be written in the form (x+m)^2+n find the value of m and the value of n b) use your answer to part (a) to find the positive solution to x^2+4x-6=0
Answer:
see explanation
Step-by-step explanation:
Using the method of completing the square.
Given
f(x) = x² + 4x - 6
add/subtract ( half the coefficient of the x- term )² to x² + 4x
f(x) = x² + 2(2)x 6 + 4 - 4 - 6
= (x + 2)² - 10
with m = 2 and n = - 10
To solve the equation let f(x) = 0 , that is
(x + 2)² - 10 = 0 ( add 10 to both sides )
(x + 2)² = 10 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt{10}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{10}[/tex]
The positive solution is
x = - 2+ [tex]\sqrt{10}[/tex] ≈ 1.16 ( to 2 dec. places )

Answer:
-5
Step-by-step explanation:
Coordinate of A = -7
Coordinate if B = 5
Distance of AB = |-7 - 5| = |-12| = 12
We are asked to find the coordinate of the point that would be ⅙ from the A to B, which is ⅙ of AB.
Let's find what ⅙ of AB is.
AB = 12
Therefore, ⅙ of AB = ⅙*12 = 2.
From point A (-7), we move 2 points towards B which will give us ⅙ from A to B.
The coordinate = -7 + 2 = -5
-5 is the coordinate of the point with a fraction distance of ⅙ from A to B.
T is the midpoint of S and U. ST=7x+4 & TU=10x-2. What is the value of SU?
Answer:
SU = 36
Step-by-step explanation:
T is the mid point so the distance of ST and TU is the same. Since ST and TU are the same, 7x + 4 = 10x - 2.
Solve for x
7x + 4 = 10x - 2
7x - 10x = - 2 - 4
-3x = -6
x = 2.
Find SU
SU = ST + TU
= (7x + 4) + (10x - 2)
substitute the value for x into the equation (x=2)
[7(2) + 4] + [10(2) - 2] = 36

Which of the following lists has numbers arranged in INCREASING order?
Answer:
C
Step by step explanation:1/7 is greater than 1/8 so 1/7 must go after it. but negative is always less then positive so the correct order is
-1/8, -1/7, 1/8, 1/7
The numbers arranged in increasing order is
-1/8, -1/7, 1/8, 1/7
There are 4 values given:
1/7, 1/8, - 1/7, - 1/8
Negative figures are generally lesser than positive figures
1/7 is greater than 1/8
In negative values, the greater number becomes the smaller number
Therefore,
-1/8 is the the smaller number
Arrangements in increasing order =
-1/8, -1/7, 1/8, 1/7

As it is a Right angled triangle, taking reference angle as angle B.
hypotenuse (h)= AB
perpendicular (p)= 12
base (b)= 24.
Now, let's look which ratio can be used here as p and b are given. Let's use tan ratio here.( as tan = p/b)
[tex] \tan(theta) = \frac{p}{b} [/tex]
[tex]tan(theta) = \frac{12}{24} [/tex]
[tex] \tan(theta) = \frac{1}{2} [/tex]
or, tan theta = (0.5)
Shifting tan to right side making it inverse.
or, theta = tan inverse (0.5)
Therefore, theta = 26.56° or 27° { by rounding off 26.56° we get 27°}.

if 5 a solution of 3x + 30 = 9x?
Answer:
x = 5
Step-by-step explanation:
This equation can be rearranged in order to easily solve.
First, rearrange the equation by simply flipping it.
3x + 30 = 9x → 9x = 3x + 30
Then, you may solve for x.
9x = 3x + 30 subtract 3x from both sides of the equation
6x = 30 divide by 6 on both sides of the equation
x = 5

Find the sum of -2 + i and its complex conjugate.
Write your answer in the form a + bi.
Answer:
- 4
Step-by-step explanation:
The conjugate of - 2 + i is - 2 - i, thus
- 2 + i + (- 2) - i
= - 2 + i - 2 - i ← collect like terms
= - 4 ← in the form a + bi with b = 0
The sum of -2 + i and its complex conjugate is:
w = -4 + 0i
How to find the sum?
The complex conjugate of a number z = a + bi is:
z' = a - bi.
Then the complex conjugate of -2 + i is -2 - i.
The sum will give:
w = -2 + i + (-2 - i) = -4 + 0
Writing it in the wanted form we get:
w = -4 + 0i

Laurie was completing the treasurer's report for her son's Boy Scout troop at the end of the school year. She didn't remember how many boys had paid the $24 full-year registration fee and how many had paid a $16 partial-year fee. She knew that the number of boys who paid for a full-year was ten more than the number who paid for a partial-year. If $400 was collected for all the registrations, how many boys had paid the full-year fee and how many had paid the partial-year
Answer:
14 boys paid for the full year fee and 4 boys paid for the partial year fee
Step-by-step explanation:
Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:
24x + 16y = 400
x = y + 10
Solve by substitution by plugging in y + 10 as x:
24x + 16y = 400
24(y + 10) + 16y = 400
Solve for y:
24y + 240 + 16y = 400
40y + 240 = 400
40y = 160
y = 4
Then, plug in 4 as y to find x:
x = y + 10
x = 4 + 10
x = 14
So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.

Describe a ratio in words about the coins that compares the whole coin collection to one part of it. Then write the ratio in at least two different ways.
Answer:
Kindly check explanation
Step-by-step explanation: A ratio which compares a whole coin collection to a part of it would be expressed in such a way that, the numerator will be the part of the coin which is being compared and the denominator being the value of the entire coin. Mathematically, It could be expressed in proportion form as ;
(Part or amount of the coin which is being compared / total value of entire coin)
A / B such that;
A = value or amount of coin which is being compared.
B = value of the entire coin.
Or in the form
A : B
part of coin being compared : blue of entire coins

When x=3 ,y=16 and when x=6 y=8. Which inverse variation equation can be used to model this function?
Answer:
[tex]y=\frac{48}{x}[/tex]
Step-by-step explanation:
When x = 3, y = 16
When x = 6, y = 8
We need to model the inverse variation.
Inverse Variation : When one value increase another value decrease. But product of both always constant.
[tex]xy=k[/tex]
when x=3, y=16
k=48
When x=6, y=8
k=48
Model of the inverse variation:
[tex]y=\frac{48}{x}[/tex]
Hence, The model of inverse variation is
[tex]y=\frac{48}{x}[/tex]
Answer:
The inverse variation equation can be used to model this function is:
[tex]y=\frac{48}{x}[/tex]
Step-by-step explanation:
An inverse relationship between two variables implies that if the value of one variable increases the value of the other variable will decreases and vice-versa.
The inverse function describing the relationship between x and y is as follows:
[tex]y=\frac{a}{x}[/tex]
Here, a is a constant.
It is provided that when the value of x is 3 the value of y is 16.
Compute the value of a as follows:
[tex]y=\frac{a}{x}[/tex]
[tex]16=\frac{a}{3}\\\\[/tex]
[tex]a=48[/tex]
It is also provided that when the value of x is 6 the value of y is 8.
Compute the value of a as follows:
[tex]y=\frac{a}{x}[/tex]
[tex]8=\frac{a}{6}\\\\[/tex]
[tex]a=48[/tex]
The value of a is 48.
Then the inverse variation equation can be used to model this function is:
[tex]y=\frac{48}{x}[/tex]
