Answer:
A. 11 m
Step-by-step explanation:
Given that
the ten workers are fencing 25 m by 28 m
And, they finished the fencing 95 m
We need to find out the number of more meter of fence that could be developed
So,
= (25+25) + (28+28)
= 106 - 95
= 11
Hence, 11 more meters should be build
Therefore the correct option is A.

Write a paragraph (4-5 sentences) explaining how we can help or change racism to black people
No copying from internet please
Answer
A few ways we could stop racism against black people in this country is to stop the perpepuation of black stereotypes in media. Such as the loud, aggressive black man, or the rude, catty black woman. It causes a harmful view on black people and can result in racial profiling. Another way to combat this racism is to fight off systemic racism. Black people who have unique names, usually African names, are more likely to get turned down for a job when they turn in their resume to an establishment. This is because they automatically assume that they'll be trouble, and won't be a good worker.
How to find right triangle with Pythagorean theorem
Answer:
By using the formula of;
A² + B² = C²
Where A and B could be either of the 2 legs and C always have to be the hypotenuse of the right triangle. Hypotenuse is the longest leg of the triangle is the leg that's opposite to the right angle of the right triangle.

What is the length of X?
Answer:
x = 85
Step-by-step explanation:
Its a Pythagorean theorem question, being a^2 + b^2 = c^2.
and knowing that 168 is the entire base we would divide by 2 to get 84 as b.
The new equation would be 13^2 + 84^2 = c^2
Then squaring them to get 169 + 7056 = c^2
Then add them together and square root them [tex]\sqrt{x}[/tex] 7225 = c
The square root is 85 making it equal x.

Answer:
10. A) 120°
11. D) 40°
12. D) 54°
13. A) 101°
Step-by-step explanation:
The applicable rules of angles and arcs are ...
the whole is the sum of the partsarcs of a circle total 360°an inscribed angle intercepts an arc of twice its measure__
10) Angles C and L intercept the same arc (DE) so will have the same measure.

11) Arc VW is twice the measure of angle X, so ...
9x +8 = 2(5x)
8 = x . . . . . . . . . subtract 9x
∠VXW = 5x = 5(8) = 40 . . . degrees
__
12) Arc EFG is twice the measure of angle W, so ...
70° +FG = 2(88°)
FG = 106° . . . . . . . . . subtract 70°
Arc FGW is twice the measure of angle E, so ...
106° +GW = 2(80°)
GW = 54° . . . . . . . . . . subtract 106°
__
13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.
RS +ST +TR = 360°

Which is the solution for the system of equations? Y = 2x-3
Y = -x
A. (1, -1)
B. No solution
C. (-1, 1)
D. (-1, -1)
Answer:
(1,-1)
Step-by-step explanation:
[tex] \large{ \begin{cases} y = 2x - 3 \\ y = - x \end{cases}}[/tex]
Since both are y-isolated equation. We can combine both.
[tex] \large{2x - 3 = - x}[/tex]
Since we want to solve for x-term, we need to isolate x-term.
So we move from -x which is the right side to x.
[tex] \large{2x - 3 + x = 0} \\ \large{3x - 3 = 0} \\ \large{3x = 3} \\ \large{x = 1}[/tex]
But we are not done yet. Solving system of equations, you must solve for y-term as well. (Because we have to answer in ordered pairs which are (x, y))
Substitute x = 1 in any given equations but I will substitute x = 1 in y = -x
[tex] \large{y = - x} \\ \large{y = - 1}[/tex]
Since we have got y-value. Therefore the answer is (1,-1)
Find the measure of an angle in a regular polygon with 22 sides
If A+B+C=[tex]\pi[/tex] show that tan A + tan B +tan C = tan A.tan B.tan C
Answer:
[tex]a + b + c = \pi \\ = > c= \pi - a - b \\ < = > \tan(c) = \tan(\pi - a - b) = -\tan(a + b) [/tex]
Step-by-step explanation:
we have:
[tex] \tan(a) + \tan(b) + \tan(c) \\ = \tan(a) + \tan(b) - \tan(a + b) \\ = \tan( a) + \tan(b) - \frac{ \tan(a) + \tan(b) }{1 - \tan(a) \tan(b) } \\ = \frac{ ( \tan(a) + \tan(b) ) \tan(a) \tan(b) }{ \tan(a) \tan(b) - 1 } (1)[/tex]
we also have:
[tex] \tan(a) \tan(b) \tan(c) \\ = - \tan(a) \tan(b) \tan(a + b) \\ = \frac{ -(\tan( a ) + \tan(b) ) \tan(a) \tan(b) }{1 - \tan(a) \tan(b) } \\ = \frac{( \tan(a) + \tan(b)) \tan(a) \tan(b) }{ \tan(a) \tan(b) - 1 } (2)[/tex]
from (1)(2) => proven
Are the polynomial functions even or odd ?
If you mirror the graph along the x axis and it lies on itself ( mirror image) it is even, if not it is odd.
If you mirror the top graph the high/ low points would be opposite so the top graph is odd
The bottoms graph can be mirrored so the bottom graph is even.

13. What is the pressure on the bottom of a water tank filled to a depth of 4 feet? O A. 1.73 psi OB. 62.4 psi C. 249.6 psi D. 184.2 psi
Pressure is defined as the force applied perpendicular to an object's surface per unit area across which that force is dispersed. The correct option is A.
What is pressure?Pressure is defined as the force applied perpendicular to an object's surface per unit area across which that force is dispersed.
The density of water is equal to 997 kg/m³, while the acceleration due to gravity is 9.81 m/s², also, given the depth of the water is 4 feet(1.2192 meters). Therefore, the pressure on the bottom of a water tank filled to a depth of 4 feet is,
Pressure = ρ × g × H = 997 × 9.81 × 1.2192 = 11924.47 N/m²
Now, If we convert the pressure from N/m² to psi, then we have to divide 11924.47 N/m² by 6895, therefore, the pressure will be,
Pressure = 11924.47 N/m² / 6895 = 1.729 psi ≈ 1.73 psi
Hence, the correct option is A.
