Answer: 20% of the teachers are from district M
There are 50 teachers from district M, so bar M is 50 units tall.
=======================================================
Work Shown:
Let's add up the bar heights of the bars shown in the chart.
J+K+L+N = 50+80+30+40 = 200
So 200 teachers are from districts J,K,L, or N.
We're told that 250 total teachers attended. This must mean M = 50. We're effectively solving 200+M = 250.
So you'll need to draw a bar over M such that it is 50 units tall. This will complete the chart.
Because there are 50 teachers from district M, out of 250 total, we can then compute the percentage to get
50/250 = 0.20 = 20%
So 20% of the teachers are from district M.
what is the equation of the following line?
Answer:
y = -3x
Step-by-step explanation:
The total surface area of this cuboid is 112cm^2. Find the value of x.
Please explain, don’t just give the answer.
Answer:
The value of x is 3
Step-by-step explanation:
Let us study the face of the cuboind
∵ The cuboid has 6 rectangular faces
∵ Each opposite faces area equal in areas
∴ 2 faces of dimensions 10 cm and 2 cm
∴ 2 faces of dimensions 10 cm and x cm
∴ 2 faces of dimensions 2 cm and x cm
∵ The total surface area of the cuboid is the sum of the areas of the 6 faces
∵ The area of the rectangle = length × width
∴ The total surface area = 2(10 × 2) + 2(10 × x) + 2(2 × x)
∴ The total surface area = 2(20) + 2(10x) + 2(2x)
∴ The total surface area = 40 + 20x + 4x
→ Add the like terms 20x and 4x
∴ The total surface area = 40 + 24x
∵ The total surface area of this cuboid is 112 cm²
→ Equate the two sides of the total surface area
∴ 40 + 24x = 112
→ Subtract 40 from both sides
∵ 40 - 40 + 24x = 112 - 40
∴ 24x = 72
→ Divide both sides by 24
∴ x = 3
∴ The value of x is 3
Answer:
= 3
Step-by-step explanation:
(easier way to solve it)
x = L, 10 = B, 2 = W
L x B
x 10 = A1
L x W
x 2 = A2
B x W
10 x 2 = 20 (A3)
= 112cm^2 / 2 = 56cm - 20 = 36
3 x 10 = 30
3 x 2 = 6
30 + 6 = 36
36 + 20 = 56cm
56cm x 2 = 112cm^2
(i hope this actually makes sense, things work differently in my mind)
In right triangle, ABC m\angle A=37 find the measure of angle B.
Answer:
B = 53 degrees
Step-by-step explanation:
37+90=127
180-127=53
If the measure of the angle ∠A is 37°. Then the measure of the angle ∠B will be 53°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
In the right triangle ΔABC, the measure of the angle ∠A is 37°.
Angle A and angle B are complementary angles. Then the equation is given as,
∠A + ∠B = 90°
37° + ∠B = 90°
∠B = 90° - 37°
∠B = 53°
If the measure of the angle ∠A is 37°. Then the measure of the angle ∠B will be 53°.

What is the value of x?
Answer:
x ≈ 6.8
Step-by-step explanation:
since all angles in a triangle add up to 180º:
8x-4+17x-23+3x+17=180
28x-10=180
28x=190
x ≈ 6.8
Find the inequality represented by the graph.
Answer:
y>4x-2
Step-by-step explanation:
First let us find the equation of the line.
Given points (1,2) and (0, -2), the slope would be
(2-(-2))/(1-0) = 4/1= 4
The intercept is at -2, so the full equation would be
y=4x-2
However, we need to find the inequality of the graph. Everything greater than our line/above our line is included. Also notice that the line is dotted, which means that the line itself is not included.
Our equations should be,
y>4x-2

Answer:
The distance between points A and B is 13
Step-by-step explanation:
We need to find distance between points A and B
Looking at the graph,
Point A : (2,6) and Point B: (-3,-6)
We need to find the distance between these points.
The formula used is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\[/tex]
We have Points A : (2,6) and B: (-3,-6)
So, [tex]x_1=2, y_1=6, x_2=-3, y_2=-6[/tex]
Putting values in formula and finding distance
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\Distance=\sqrt{(-3-2)^2+(-6-6)^2} \\Distance=\sqrt{(-5)^2+(-12)^2} \\Distance=\sqrt{25+144} \\Distance =\sqrt{169}\\Distance = 13[/tex]
So, the distance between points A and B is 13

The equation of a circle in the x-y plane is shown above. What is the Radius of the Circle
2

9
Answer:
r = 2
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² + 4x - 2y = - 1 ← rearrange the x and y terms together
x² + 4x + y² - 2y = - 1
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(2)x + 4 + y² + 2(- 1)y + 1 = - 1 + 4 + 1
(x + 2)² + (y - 1)² = 4 ← in standard form
with r² = 4 ⇒ r = [tex]\sqrt{4}[/tex] = 2

3) First four terms are: 8,13,20,29
4) First four terms are: 0,0,2,6
5) First four terms are: 0,1,1.41,1.73
Step-by-step explanation:
1.
n 1 2 3 4 5 6
f(n) 12 24 36 48 60 72
Domain: { 1,2,3,4,5,6}
Range: {12,24,36,48,60,72}
Write first four terms of each sequence
2) f(n)=3n-1
Put n = 1, 3(1)-1 = 3-1 = 2
Put n = 2, 3(2)-1 = 6-1 = 5
Put n = 3, 3(3)-1 = 9-1 = 8
Put n = 4, 3(4)-1 = 12-1 = 11
So, First four terms are: 2,5,8,11
3) f(n)=n^2+2n+5
Put n = 1, (1)^2+2(1)+5= 1+2+5 = 8
Put n = 2, (2)^2+2(2)+5 = 4+4+5= 13
Put n = 3, (3)^2+2(3)+5 = 9+6+5 = 20
Put n = 4, (4)^2+2(4)+5 = 16+8+5 = 29
So, First four terms are: 8,13,20,29
4) f(n)=(n-1)(n-2)
Put n = 1, (1-1)(1-2) = 0(-1) = 0
Put n = 2, (2-1)(2-2) = 1(0) = 0
Put n = 3, (3-1)(3-2) = 2(1) = 2
Put n = 4, (4-1)(4-2) = 3(2) = 6
So, First four terms are: 0,0,2,6
5) f(n) = [tex]\sqrt{n-1}[/tex]
Put n=1 [tex]\sqrt{1-1}=\sqrt{0}=0[/tex]
Put n=2 [tex]\sqrt{2-1}=\sqrt{1}=1[/tex]
Put n=3 [tex]\sqrt{3-1}=\sqrt{2}= 1.41[/tex]
Put n=4 [tex]\sqrt{4-1}=\sqrt{3}=1.73[/tex]
So, First four terms are: 0,1,1.41,1.73
