Explanation:
Less Men, means more Days {Indirect Proportion}
Let the number of days be x then,
27 : 36 :: 18 : x
[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]
=>27x = 36 * 18
=> x = 24
So 24 days will be required to get work done by 27 men..
Answer:
36 men can complete work in 18 days
so, one man can complete work in 18×36 days
Therefore, 27 can complete work in 18×36/27 = 24 days

A. identify the vertex
B. Identify the intercept
C. Write the equation of the graph above
D. Fill in the end behavior:
As x , y ____
As x 3, y ____
E. Identify the domain and range:
We want to identify different things on the given graph.
The solutions are:
A) (3, -1)
B) x = 4
C) x = y^2 + 2y + 4
D) x ⇒ ∞, y ⇒ ∞
x⇒3, y⇒ -1
A) The first thing we want to identify is the vertex, we could say that a vertex is a point of symmetry. (like the minimum/maximum of a parabola). Here we clearly do not have a point of symmetry, as we only have half of a parabola, but if it was a complete one, the vertex would be at the blue point, in (3, -1)
B) This is the point where the graph intercepts the x-axis, x = 4.
C) we want to write the equation, we start with the general parabola, this time as a function of y:
x = a*y^2 + b*y + c
Remember that the x-itercept is at x = 4. then c = 4.
x = a*y^2 + b*y + 4
The y-value of the vertex is -1, while the general y-value of the vertex is:
y = -b/2a = -1
And evaluating the equation in this value, gives us:
x = a*(-1)^2 + b*-1 + 4 = 3
Then we have two equations:
-b/2a = -1
a + -b + 4 = 3
We can rewrite the first one as:
-b = -2a
b = 2a
Now we can replace this on the other equation:
a - 2a + 4 =3
-a + 4 = 3
-a = 3 - 4 = -1
a = 1
And b = 2a = 2*1 = 2
Then the equation of the parabola is:
x = y^2 + 2y + 4
D) We can see that as x grows, y increases, so we can say that:
x ⇒ ∞, y ⇒ ∞
And for the other limit we can see that as x tends to 3, y tends to -1, then:
x⇒3, y⇒ -1

Answer:
v = 1
u = 2
Step-by-step explanation:
Given is a special right triangle with angle measures as follows:

The side lengths would be :
2x- x[tex]\sqrt{3}[/tex]-x
in the image it shows that the second side length (the one that sees angle measure 60) is [tex]\sqrt{3}[/tex] from this we can conclude x = 1 so:

Triangle EFG is congruent to triangle JKL.
What is KL, in units?
Applying the theorem of congruent triangles, since FG = 6 units and FG and KL are congruent, therefore:
KL = 6 units
Recall:
Congruent triangles have the same shape and size.Congruent triangles have all corresponding angles and side lengths congruent to each other.Given that:
[tex]\triangle EFG \cong \triangle JKL[/tex],
therefore,EF = JK
FG = KL, and
EG = JL
Thus, since FG = 6 units and FG and KL are congruent, therefore:

Answer:
324 ft²
Step-by-step explanation:
Given 2 similar figures with ratio of sides a : b , then
ratio of areas = a² : b²
Here ratio of sides = 3 : 18 = 1 : 6
ratio of areas = 1² : 6² = 1 : 36
That is the area of the larger parallelogram is 36 times the smaller
area of larger parallelogram = 36 × 9 = 324 ft²

Max is conducting a study on the most used phone applications among a group of 500 students at Fairmont High School. 150 students reported using Snapshot most, while 200 students reported favoring Instapic. The rest of the students reported using Photobooth. What is the ratio of the number of students using Photobooth to those students using Instapic?
Answer:200:150
Step-by-step explanation:
Answer: 3:4
Step-by-step explanation:
Choice B is the correct answer. The number of students using Photobooth is equal to
500 - (150+200) = 150
people. To find the ratio of students using Photobooth to those using Instapic:
150/200 = 3/4
This fraction can be converted to a ratio, of 3:4

Place the following steps in order to describe how to solve the following equation: 2(2x+3)-2=5
Answer:
0.25
Step-by-step explanation:
First, you distribute the equation.
2(2x+3)-2=5
4x+6-2=5
Then, you combine like terms.
4x+6-2=5
4x+4=5
Next, you subtract 4 from each side.
4x+4=5
4x+4-4=4x
5-4=1
4x=1
Finally, you divide each side by 4.
4x/4
1/4
(4x/4 you'd end up with x)
Answer: x=1/4

Step-by-step explanation:
To solve this question you need to know some properties of a parallelogram which is the shape given.
Firstly, remember that in a parallelogram opposite angles are equal.
Secondly, remember that the diagonals of a parallelogram bisect each other.
Lastly, remember that the sum of the interior angles of a quadrilateral or a parallelogram is 360°.
So, by using the first property we can see that because [tex]<[/tex]PQR=70° then [tex]<[/tex]PSR must be equal to 70° as well.
Now, we can use the last property to find [tex]<[/tex]SPQ then, use the second property to find [tex]x[/tex].
Let's name [tex]<[/tex]SPQ, [tex]y[/tex].
and That gives:
[tex]2y+140=360[/tex]
Subtract 140 from both sides:
[tex]2y=360-140[/tex]
[tex]2y=220[/tex]
[tex]y=\frac{220}{2}[/tex]
[tex]y=110[/tex]
So, [tex]<[/tex]SPQ=110 and
Now using the second property we can find that:
[tex]<[/tex]SPQ=[tex]2x[/tex]
And [tex]2x=110[/tex]
[tex]x=\frac{110}{2}[/tex]
[tex]x=55[/tex]

Answer:
12/18 and 10/15
Step-by-step explanation:
12/18 = 2/3 (when the numerator and denominator are divided by 6)
10/15 = 2/3 (when the numerator and denominator are divided by 5)
∴ 12/18 and 10/15 are equivalent
For any two real numbers, a and b one and only one of these relations is true:
1. a = b
2. a < b
3. a > b
Answer:
For real numbers according to the Law of Trichotomy,
if a = b then a will never be greater than b and a will never be less than a.
if a<b then a will never be equal to b and a will never be greater than b.
if a>b then a will never be less than b and a will never be equal to b.
And vice versa to b as well.
That means only one property will hold for given two numbers.
