Hello There!
This question has to do with proportionalities
The first thing we want to do is create a proportional relationship between the total amount of trains to the amount of trains that are full
It said that out 14 trains 10 were full
so the proportional relationship would be
10 to 14
now we want to find how many trains would be full out of 7
to do so we set up an equation using our formed proportion
let x = number of full trains
[tex]\frac{10}{14} =\frac{x}{7}[/tex]
now we solve for x
to solve for x we want to isolate the variable (x) and get rid of the 7
to do so we multiply each side by 7
[tex]\frac{x}{7} 7=x\\\frac{10}{14} 7=5[/tex]
we're left with x = 5
hence we can expect 5 trains to be full out of 7

The Trinomial factors are...
Step-by-step explanation:
Since you are solving for two numbers that multiply into 56 and since we know they are both integers then they have to be an integral multiple of 56 which are 1,2,4,7,8,14,28, and 56. There are also negative values for every single value listed.
I will restate the example products
so 1 would be paired with 56 to get a product of 56
and -1 with -56 would be a product of 56
2 with 28 to get 56
-2 with -28 to 56
4 with 14 to get 56
-4 with -14 to get 56
7 with 8 to get 56
-7 with -8 to get 56
Hope this helps :)

sin 7A = cos 3A, then m∠A is what?
Answer:
m∠A = 9°
Step-by-step explanation:
[tex] \sin 7A = \cos 3A \\ \\ \sin 7A = \sin(90 \degree - 3A) \\ \\ 7A = 90 \degree - 3A\\ \\ 7A + 3A= 90 \degree \\ \\ 10A= 90 \degree \\ \\ A = \frac{90 \degree}{10} \\ \\ m \angle A =9 \degree[/tex]

In a circle with radius 2.1, an angle intercepts an arc of length 21.2. Find the angle in
radians to the nearest 10th.
Given:
Radius of a circle = 2.1 units
Arc length = 21.2 units
To find:
The central angle in radians to the nearest 10th.
Solution:
We know that the intercepted arc length is
[tex]s=r\theta[/tex]
Where, s is the arc length, r is the radius and [tex]\theta[/tex] is the central angle in radians.
Putting the given values, we get
[tex]21.2=2.1\theta[/tex]
[tex]\dfrac{21.2}{2.1}=\theta[/tex]
[tex]10.095238=\theta[/tex]
[tex]\theta\approx 10.1[/tex]
Therefore, the angle in radians is 10.1.

What conditions would be enough to prove that P is the circumcenter of HJK ?
Answer:
Option A and C
Step-by-step explanation:
Explanation for why I choose option A :-
If you look at the triangle, HK has a midpoint of point L, HJ has a midpoint of point M, and KJ has a midpoint of point N. Now if you stretch the lines inside of the triangle, they intersect at point P which is known as the circumcenter of HJK, true.
Explanation for why I choose option C :-
Now let us look at the lines stretch inside of the triangle. There are three lines which are congruent. Those lines are PK, HP, and PJ (they are the big lines inside the triangle) are congruent. Since those three line intersect at point P, it make the statement true that P is the circumcenter of HJK.
Why option B is not an answer?We do not know the third line (PN) measurements to find that if the three lines (PL, PM, and PN) are congruent and equal 90⁰. Since we do not know, it would not prove that they are congruent and P is the circumcenter of HJK.
Why option D is not an answer?Well it says that triangle HJK is an acute triangle which is true, but this doesn't prove that P is the circumcenter of HJK.
I hope this helps, thank you :) !!
The required conditions are L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex] and [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex]. So, options A and C are correct.
Given:
The given figure of a triangle HJK.
To find:
The conditions that would be enough to prove that P is the circumcenter of HJK.
Explanation:
The circumcenter of a triangle is the intersection of perpendicular bisectors and it is equidistant from each vertex of the triangle.
P is the circumcenter of triangle HJK if PL, PM, PN are perpendicular bisectors and P is equidistant from vertices H, J, K.
PL, PM, PN are perpendicular bisectors if L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex].
P is equidistant from vertices H, J, K if [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex].
The required conditions are L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex] and [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex]. So, options A and C are correct, and other two options are incorrect.

consider the polynomial function p(x) = -5x^6-3x^5+4x^2+6x
What is the end behavior of the graph of p?
Answer:
The correct answer is C. As x approaches ±∞, p(x) approaches -∞
Step-by-step explanation:
The easiest way to see this is to consider the term with the largest power of x. In this case that's the first term -5x⁶. Because the exponent is an even number, the function will ultimately move in the same direction as x approaches infinity. If the exponent was odd, like -5x⁷, then they'd be moving in opposite directions.
The next thing to consider is the coefficient. If the coefficient is positive, then the left side of the curve goes downward, and the right side goes either downward or upward depending on the exponent. If the coefficient is negative, then the left side goes upward, and the right side goes upward or downward depending on the coefficient.
In this case, we have a negative coefficient, so the left side goes downward, and an even power, so the right side goes the same way as the left side.
The correct answer is C. As x approaches +∞, function p(x) approaches -∞and vice versa.
What is polynomial?Polynomial is a combination of algebraic terms may be in addition, subtraction, multiplication, division.
How to find value of function?In the case the first term is -5x⁶. Because the exponent is an even number, the function will move in the same direction as x approaches infinity. If the exponent was odd, like -5x⁷, then they would be moving in opposite directions.

Answer:
5p + 2(p-2)
simplified to: 7p-4
Step-by-step explanation:
Q. states that shop opens for p hours on weekdays
this means that to find the total number of hours on weekdays it would be 5 times p, thus 5p
On weekends, "shop opens 2 hours less" , which means 2 hours less than p.
Thus hours for both saturday and sunday
2(p-2)
Total would be adding those two together
5p + 2(p-2)
expand 2(p-2) = 2p-4
thus, 7p-4
Find the value of y.
y=
Answer:
0.5
Step-by-step explanation:
AB and AC are tangents from point A to the circle with center P at points B and C respectively.
Measures of the tangents drawn from external points to a circle are equal.
Therefore,
11y = 3y + 4
11y - 3y = 4
8y = 4
y = 4/8
y = 0.5

Fill in the blank: A rectangle is a special parallelogram with equal right angles and 4 pairs of __________sides.
Answer:
Parallel sides
Step-by-step explanation:
A rectangle has all of its interior angles equal to each other and inclined at a degree of 90.
The two opposite sides of a rectangle are parallel to each other.
Parallel lines are lines that will never meet, no matter how long that they are extended.
If we can extend the two sides of the rectangle facing each other, we will be able to see that they will never meet no matter how far they are extended.
Thus, the rectangle has 2 pairs of parallel lines
