Answer:

36

Step-by-step explanation:

you have to times the base by height. so basically, the formual is A(area)=bh (base x height). in this case it is 9x4.

Answer:

The answer is 36.

Step-by-step explanation:

Imagine chopping the parallelogram into half.

You will have a height of 4 cm and a length of 9.

Now multiply.

9x4=36

Answer:

2-(3x-4) = 2x -9

-6x + 8 = 2x - 9

6x = 17

x = 2.833

Answer:

y = 4, x=1 or x=110

Step-by-step explanation:

1. 4y-2=18                      2. x/2+5=11

       -2  -2                         x/10=11

4y = 16                               x=1

4y/4 = 16/4                         or

y=4                                  x/10=11

                                       0.1x=11

                                        0.1x/0.1 = 11/0.1

                                         x=110

Answer:

Area of square field = 900 m²

To find :

Time to take 10 round with the speed of 6 km/h

Now, firstly we'll find the distance for one round which is perimeter of the square field.

=> Perimeter = 4 × side.

We'll find side the helps of area

=> Area = 900 m²

=> Side × Side = 900

=> Side = √900

=> Side = 30 m

Now, perimeter of the field

=> Perimeter = 4 × 30

=> Perimeter = 120 m

Now, he have to take 10 round,. so distance covered in 10 round will be 10 × distance in one round

=> Total distance = 10 × 120

=> Total distance = 1200 m

Now we'll find time

=> Time = Distance/speed

Now the distance is in meter and we have to convert it in Km

=> 1200 m = 1200/1000 km

=> 1200 m = 1.2 km

Now putting all the values

=> Time = Distance/speed

=> Time = 1.2 / 6

=> Time = 0.2 hour

Or

=> Time = 0.2 × 3600 seconds

=> Time = 720 seconds.

Hope It Helps.

Answer:

4x-5y=40

comparing with y=MX+C (equation of a straight line)

we have,

-5y= -4x+40

divide through by. -5

we have,

y= 4/5X - 40/5

therefore,

y= 4/5X - 8

Hence, 4/5 is the slope while -8 is the y-intercept

Rewrite the fractions as decimals:

3/2 = 1.5 ( this terminates)

2/3 = 0.666…. (this does not terminate)

3/4 = 0.75 ( this terminates)

5/7 = 0.71428…. ( this does not terminate)

Step-by-step explanation:            

let angles be 3x, 5x, 10x

3x+5x+10x=180(angle sum property)

18x=180

x=180/18

x=10

therefore, angles are 3*10=30

Answer: y= 3x-1

Step-by-step explanation:

Equation of a straight line:

y = mx + b ------(i)

Step by Step Solution:

Step 1: Calculating Slope (m).

m =

y2-y1

x2-x1

m =

2--1

1-0

m =

3

1

m = 3

Now putting value of m in equation (i)

y = 3x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (0,-1) for calculating y-intercept:

y = mx + b

-1 = 3(0) + b

-1 = 0 + b

-1 = b

b = -1

Answer:

y=3x-1

Step-by-step explanation:

Hi there!
We are given a line, and we want to find the equation of that line in slope intercept form

Slope-intercept form is given as y=mx+b, where m is the slope, and b is the y intercept

First, we need to find the slope of the line

The slope of the line can be calculated from 2 points with the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We can take any 2 points from the line to help us; for example, we can take (0,-1), and (1,2), which are both on the line

We can label the values of the points to avoid confusion while we calculate the slope:
[tex]x_1=0\\y_1=-1\\x_2=1\\y_2=2[/tex]
Now let's plug these values into the formula to solve for the slope:

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{2--1}{1-0}[/tex]

Simplify:

m=[tex]\frac{2+1}{1-0}[/tex]

Add/subtract:

m=[tex]\frac{3}{1}[/tex]

m=3

The slope of the line is 3
Remember that our equation is y=mx+b; we can plug 3 as m into the equation right now.

This is our equation so far:

y=3x+b

Now we need to find b
The y intercept (b) is the point in where the line intersects with the y axis; the value of x is 0 at that point

Since we have the graph given, we can find the value of the y intercept by finding the point that crosses (intersects) the y axis.

That point would be (0, -1)

The value of b is simply the value of y at this point; in this case, the value of b is -1

So plug -1 as b into the equation:

y=3x-1

Hope this helps!

Answer:

Step-by-step explanation:

You want the factors that would create the array of tiles shown.

Each column consists of a rectangle and two squares. If we assume a rectangle represents "x" and a square represents "1", then each column is a representation of x + 1 + 1 = x +2.

Each row is three repetitions of the tile in the first column. This means the factor being represented here is 3.

The two factors that are multiplied to give this array of tiles are ...

  3  and  x+2

Their product is ...

Step-by-step explanation:

so, yes, the area of a triangle is

baseline × height / 2

so, we have here

16 = 8 × height / 2 = 4 × height

height = 16/4 = 4 in.

One of the ways to solve a system of equation is by using the substitution method

The values of x and y are -9 and 5

The equations are given as:

2x + 6y = 12

x + y = -4

Make x the subject in the second equation

x = -4 - y

Substitute x = -4 - y in the first equation

2(-4 - y) + 6y = 12

Expand

-8 - 2y + 6y = 12

Add 8 to both sides

- 2y + 6y = 20

So, we have:

4y =20

Divide through by 4

y = 5

Recall that:

x = -4 - y

So, we have:

x = -4 - 5

x = -9

Hence, the values of x and y are -9 and 5
