Answer:

120 m squared

Step-by-step explanation:

Volume problems are very simple:

Just multiply the base x height x length

So 10 x 2 x 6, which is 120.

Therefore, the volume of this shape is 120 m squared.

Answer:

120 m

Step-by-step explanation:

Simply Multiply all the given measurements so

10m x 2m x 6m = 120m

So as simple as that.

Select the correct answer. Which graph represents the solution to this inequality? A. B. C .

Answers

Answer: C

Step-by-step-explanation: Given

- (12x + 8) ≤ - 2x + 11 ← distribute parenthesis on left side

- 3x - 2 ≤ - 2x + 11 ( add 3x to both sides )

- 2 ≤ x + 11 ( subtract 11 from both sides )

- 13 ≤ x , thus

x ≥ - 13

Since x can equal - 13 then a solid circle at - 13 represents the solution

Since x greater than - 13 then the arrow is facing to the right of - 13 on the number line.

Then the graph representing the solution is C

Question 3
Find the equation of the line joining (-2,4) and (3,7)

Answers

Answer:

y = (3/5)x+26/5 or 5y = 3x+26

Step-by-step explanation:

Applying,

The equation of a line in two point form

(y₂-y₁)/(x₂-x₁) = (y-y₁)/(x-x₁)............... Equation 1

From the question,

Given: y₂ = 7, y₁ = 4, x₂ = 3, x₁ = -2

Substitute these values into equation 1

(7-4)/[3-(-2)] = (y-4)/(x+2)

3/5 = (y-4)/(x+2)

5(y-4) = 3(x+2)

5y-20 = 3x+6

5y = 3x+6+20

5y = 3x+26

y = (3/5)x+26/5

Hence the equation of the line is y = (3/5)x+26/5 or 5y = 3x+26

What is the inverse of the function f(x) = 2x + 1?

Answers

Answer:

[tex]f(x)^{-1}=\frac{x-1}{2}[/tex]

Step-by-step explanation:

start by replacing f(x) for y:

y = 2x + 1

switch y and x:

x = 2y+1

solve for x by first subtracting 1 from both sides:

2y = x-1

divide 2 from both sides:

y = [tex]\frac{x - 1}{2}[/tex]

replace y with [tex]f(x)^{-1}[/tex]:

[tex]f(x)^{-1}=\frac{x-1}{2}[/tex]

Find the surface area of the "unrolled" cylinder where a = 4 cm and b= 10 cm.
Leave your answer in terms of Pi

Answers

Answer:

= 140.544cm^2

Step-by-step explanation:

Given data

a is the radius=4cm

b is the lenght= 10cm

We two circles, hence the area of the circles is given as

Area= 2(πr^2)

Area= 2(3.142*4^2)

Area= 2(50.272)

Area= 100.544cm^2

Area of the rectangular shape= 4*10= 40cm^2

Hence the total area = 100.544+40

= 140.544cm^2

Solve the equation y - 2.7 = -2.0 + 2y

Answers

Answer:

y = -0.7

Step-by-step explanation:

Reorder the terms:

-2.7 + y = -2.0 + 2y

Solving

-2.7 + y = -2.0 + 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

-2.7 + y + -2y = -2.0 + 2y + -2y

Combine like terms: y + -2y = -1y

-2.7 + -1y = -2.0 + 2y + -2y

Combine like terms: 2y + -2y = 0

-2.7 + -1y = -2.0 + 0

-2.7 + -1y = -2.0

Add '2.7' to each side of the equation.

-2.7 + 2.7 + -1y = -2.0 + 2.7

Combine like terms: -2.7 + 2.7 = 0.0

0.0 + -1y = -2.0 + 2.7

-1y = -2.0 + 2.7

Combine like terms: -2.0 + 2.7 = 0.7

-1y = 0.7

Divide each side by '-1'.

y = -0.7

Simplifying

y = -0.7

Find the value of x in the isosceles triangle shown below.​

Answers

Answer:

option A

Step-by-step explanation:

Let  x = y + y

Now using Pythagoras theorem :

                                    [tex]15^2 = y^2 + 12^2\\225 = y^2 + 144\\225 - 144 = y^2\\81 = y^2\\9 = y[/tex]

Therefore , x = y + y = 18

Answer:

(x/2)²+12² =15²

(x/2)²+144=225

(x/2)²=225-144

x²/4. =81

x² =81×4

x. =√81×4

a circle shown below, m AC = 89° and m BC = 153°. Determine m∠ACB.

Answers

Answer:

m<ACB  = 59degrees

Step-by-step explanation:

To get <ACB, first we need arcAB

arcAB + arcAC + arcBC = 360

arcAB + 89 + 153 = 360

arcAB+242 = 360

arcAB = 360 - 242

arcAB = 118

Also, m<ACB = 1/2arcAB

m<ACB = 1/2*118

m<ACB  = 59degrees

ABC was dilated to create A' B' C'. What is the center of dilation? And what is the scale factor of the dilation?

Answers

Given:

In the given figure the vertices of triangle ABC are A(-2,2), B(4,2), C(-2,-2).

The vertices of triangle A'B'C' are A'(-4,4), B'(8,4), C'(-4,-4).

To find:

The center of dilation and the scale factor.

Solution:

In the given graph, draw the lines AA', BB' and CC'. The intersection point of these lines is the center of dilation.

From the below graph, it is clear that the lines AA', BB' and CC' intersect each other at (0,0).

Therefore, the center of dilation is (0,0).

If a figure is dilated by factor k and the center of dilation is origin, then

[tex](x,y)\to (kx,ky)[/tex]

[tex]A(-2,2)\to A'(k(-2),k(2))[/tex]

[tex]A(-2,2)\to A'(-2k,2k)[/tex]

It is given that A'(-4,4). So,

[tex](-2k,2k)=(-4,4)[/tex]

On comparing both sides, we get

[tex]-2k=-4[/tex]

[tex]2k=4[/tex]

[tex]k=\dfrac{4}{2}[/tex]

[tex]k=2[/tex]

Therefore, the scale factor is 2.
