Answer:

0.71. ,14%. ,7/40

Step-by-step explanation:

At first we have to find value of 14% and 7/40

which is 14/100=0.14 and

7/40 = 0.175.

so arranging in descending order which is bigger value to smaller value so,

0.71. , 0.14. , 0.175

Answer:

The three consecutive even integers are 6, 8, 10

Step-by-step explanation:

∵ The three consecutive even numbers are x, x + 2, x + 4

∵ The smallest number is x

∴ Twice the smallest number = 2x ⇒ (1)

∵ The largest number is x + 4

∴ Three times the largest number = 3(x + 4) = 3(x) + 3(4)

∴ Three times the largest number = 3x + 12 ⇒ (2)

∵ The sum of twice the smallest number and three times the largest is 42

→ Add (1), (2) and equate the sum by 42

∴ 2x + 3x + 12 = 42

→ Add the like terms

∴ 5x + 12 = 42

→ Subtract 12 from both sides

∴ 5x + 12 - 12 = 42 - 12

∴ 5x = 30

→ Divide both sides by 5

∵ [tex]\frac{5x}{5}=\frac{30}{5}[/tex]

∴ x = 6

∴ The smallest integer is 6

∴ The middle integer is 6 + 2 = 8

∴ The largest integer is 6 + 4 = 10

∴ The three consecutive even integers are 6, 8, 10

Answer:

Step-by-step explanation:

Let v represent the original price of a video game.

Let b represent the original price of a board game.

let y be the total

y=v+b+12

Video games are 20% = 100-20= 80%= 0.8v

 board games are 50% =100-50=50%= 0.5b

the total is now

y=0.8v+0.5b+12

the expression for the total sale price of 2 video games, 3 board games, and 1 basketball

y=2(0.8v)+3(0.5b)+12

y=1.6v+1.5b+12

Answer:

36 in.

Step-by-step explanation:

the perimeter of the square is 4s and the perimeter of the triangle is 3(s+3).

since the perimeters are the same you can set them equal to each other and solve.

you should get s=9

substitute 9 into the square perimeter equation to get 36 in.

The slopes are:

blue: 4/3 = 1⅓

green: -4/3 = -1⅓

I used rise over run to work these out

Answer:

- [tex]\frac{4}{3}[/tex] and [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 8, 8) and (x₂, y₂ ) = (4, - 8) ← 2 points on green line

m = [tex]\frac{-8-8}{4+8}[/tex] = [tex]\frac{-16}{12}[/tex] = - [tex]\frac{4}{3}[/tex]

Repeat with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 2) ← 2 points on the blue line

m = [tex]\frac{2+1}{4-0}[/tex] = [tex]\frac{3}{4}[/tex]

Since the product of the slopes = - [tex]\frac{4}{3}[/tex] × [tex]\frac{3}{4}[/tex] = - 1

Then the lines are perpendicular

The options 1, 3 and 4 are true statements.

Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).

From the diagram,

1) ∠GNH+∠HNJ=90°

So, ∠GNH and ∠HNJ are complementary angles

2) ∠JNK+∠KNL≠180°

∠JNK and ∠KNL are not supplementary angles

3) ∠KNL+∠LNM=90°

So, ∠GNH and ∠HNJ are complementary angles

4) m∠HNK+m∠KNL=180°

∠HNK and ∠KNL are supplementary angles

5) m∠MNG+m∠GNH=90°

So, ∠MNG and ∠GNH are not complementary angles

Therefore, options 1, 3 and 4 are correct.

Answer:

The percent change is 60%.

Step-by-step explanation:

given that the old amount is

$600

also the new amount is $960

the change is 960-600= $360

therefore the expression for percent change is given as

%change= new-old/old

%change= final-initial/initial

%change= 960-360/360

%change= 360/600

%change= 0.6

0.6*100

=60%

The percent change is 60%.

Each polynomial is matched to its factored form. These are the correct answers. I did this on EDGE!

Polynomial is an expression that consists of indeterminates(variable) and coefficients.

Polynomial is an expression that consists of indeterminates(variable) and coefficients, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

To know which polynomial to match, solve the factors.

A.) (x-4)(x²+4x+16)

[tex](x-4)(x^2+4x+16)\\\\=x(x^2+4x+16)-4(x^2+4x+16)\\\\= x^3 + 4x^2 + 16x - 4x^2-16x-64\\\\=x^3 -64[/tex]

Hence, (x-4)(x²+4x+16) will match x³-64.

B.) (x+4)²

[tex](x+4)^2\\\\= x^2+8x+16\\[/tex]

Hence, (x+4)² will match x²+8x+16.

C.) (x-4)(x+4)

[tex](x-4)(x+4)\\\\ = x^2-16[/tex]

Hence, (x-4)(x+4) will match x²-16.

Step-by-step explanation:

Found the answer off some other dude

Answer:

y = -2x + 3

Step-by-step explanation:

The slope-intercept form is y = mx + b

m is the slope

b is the y-intercept

those are the only things you need to find when doing slop-intercept form.

Slope: Find 2 points on the line

ex. (0,3) ; (3, -3) I just chose ones that were not decimals

To find slope you need to do this :  y - y / x - x

you can chose any order, as long as the pairs are together, either first or second.

3 - (-3) / 0 - 3 is one way

6 / -3 is the slope

-3 - 3 / 3 - 0 is another

-6 / 3 is the slope

They are essentially the same.

you can simplify them to get -2

Y-Intercept:

this is really easy, just find where the line touches the y-axis

y-intercept = (0,3)

We have: slope = -2

               y-intercept = 3

Now, replace the m and b in the equation-

y = -2x + 3

hope this helps :)

slope = -5/12x
