What is mean by Fraction?

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

The number is,

⇒ 0.407

Now,

Since, The number is,

⇒ 0.407

Hence, The equivalent fraction will be;

⇒ 407/1000 = 0.407

And, By option B;

⇒ 11/27 = 0.407

Thus, The equivalent fraction will be;

⇒ 11/27

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:

The garden is 10 ft. wide.

Step-by-step explanation:

2 • (2w + w) = 60 here is an equation to show how I got the width (10 ft.)

2 x 3w = 60

6w = 60

Divide 6 from both sides, 6 & 6 cancel out and 60 divided by 6 is 10.

Answer :

A) y = 7x + 4

Step-by-step explanation:

we need to see the equations 1 by 1

instead of y and x we need to put the value given

I am taking the last x and yes values as they are small numbers and will be easy to calculate

x = -1

y = -3

placing the values in equation :

A) y = 7x + 4

-3 = 7 × -1 + 4

-3 = -7 + 4

-3 = -3

So we got the answer same ! so the correct answer will be A) y = 7x + 4

let's check other one too to confirm overselves

b) y = 4x + 7

-3 = 4 × -1 + 7

-3 = -4 + 7

Answer: In a 30-60-90  triangle the side opposite the 30 degree angle is half the length of the hypotenuse. The shorter leg is the side opposite the 30 degree angle, therefore the shorter leg = 30/2 = 15

By the Pythagorean theorem

the longer leg = √(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units

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

Answer: -3/4 is greater

Step-by-step explanation:

If you plot the fractions on a number line, -6/4 would be farther left than -3/4, meaning -3/4 is a bigger number.

We can solve this problem in three steps.

1) find the area of the square

[tex]a=lw\\\\a=(7.5)(6)\\\\a=45ft^{2}[/tex]

2) find the area of the triangle

[tex]a=\frac{1}{2}bh\\\\a=\frac{1}{2} (6)(4)\\\\a=12ft^{2}[/tex]

3) add the areas together

[tex]a=45+12[/tex]

Answer:

X = 21 / 4 (21 over 4)

Step-by-step explanation:

First, we combine like terms:

5x−11=x+10

Step 2: Subtract x from both sides.

5x−11−x=x+10−x

4x−11=10

Step 3: Add 11 to both sides.

4x−11+11=10+11

4x=21

Step 4: Divide both sides by 4.

4x/4 = 21/4

x= 21 / 4

Please give me brainliest of this helped you! Thanks!

Step-by-step explanation:

a.

simply add both equations

x + y = 2

-3x - y = 5

----------------

-2x + 0 = 7

x = -7/2

x + y = 2

-7/2 + y = 2

y = 2 + 7/2 = 4/2 + 7/2 = 11/2

b.

1/2 x + 2y = -13

x - 4y = 8

first multiply the first equating by 2

x + 4y = -26

x - 4y = 8

--------------------

2x + 0 = -18

x = -18/2 = -9

x - 4y = 8

-9 - 4y = 8

-4y = 17

y = -17/4
