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)

Answer:

Age of Nicole x= 24 years

Age of Donald = y = 48 years

Step-by-step explanation:

Suppose x represents Age of Nicole in years and y represents age of Donald in years

Sum of their ages is 72, therefore

[tex]x+y=72[/tex] -------------- (1)

Nicole is half as old as Donald

[tex]x= \frac{y}{2}[/tex]   ------------------ (2)

Substitute x=y/2 in equation (1)

[tex]\frac{y}{2} +y = 72 \\3y = 2(72) \\y = \frac{144}{3} \\y= 48 \ years[/tex]

Now put y=48 in equation (2)

[tex]x =\frac{48}{2} \\x=24[/tex]

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

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.

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

Answer:

1) Domain: {   1,2,3,4,5,6}

Range: {12,24,36,48,60,72}

2) First four terms are: 2,5,8,11

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

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

I hope this helps! :)

Answer:

66

Step-by-step explanation:

angle 1 and 4 are supplementary so the 2 added together equal 180. 180-124=56.

The sum of the triangles angles equal 180

180-56-58=66 which is the value of angle 2

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
