Answer:

-1/2

Step-by-step explanation:

Slope is calculated by rise over run.

In this case, the rise is 1, and the run is -2.

So, the slope is -1/2.

The number of silver cars in the pictogram is 23.

If 16 cars are red, then, each circle represents 4 cars.

If each circle represents 4 cars, then, each quarter of a circle represents 1 car

White car = 4 + 4 + 4 + 2

= 14 cars

Silver = 4 + 4 + 4 + 4 + 4 + 3

= 23 cars

Grey = 4 + 3

= 7 cars

Total cars = red + white + silver + grey

= 16 + 14 + 23 + 7

= 60 cars

It can therefore be concluded that silver cars is 23 in number.

Answer:

9 cookies

Step-by-step explanation:

The equation is 11.1 = 0.9x + 3. First, we need to isolate the variable so we subtract 3 from both sides. 8.1 = 0.9x. Next we divide both sides by 0.9 which gives us 9 = x or x = 9.

Step-by-step explanation:

Plugin the number into sthe pythagroyean theorm (a²+b²=c²), with 3 replacing a, 4 replacing b, and x replacing c.

3²+4² = x²

9+16 = x²

25 = x²

√25 = √x²

x = 5

Explanation:

3x² − 8x + 4 = 0

Factor left side of equation

(3x − 2)(x − 2) = 0

Set factors equal to 0

3x − 2 = 0 or x − 2 = 0

Quadratic equations are a form of algebraic equations that can or cannot be factorized.

The value of x is 2  and 2/3

Quadratic equations come in the form: ax²+ bx + c = 0

Solution by completing the square for:

3x²− 8x + 4 = 0

a = 3 , a≠1 so  we divide through by 3

3x²/3 − 8x/3 +4/3 = 0/3

which gives us

x²− 8x/3 + 4/3 = 0

Subtract 4/3 from both sides

x²− 8x/3 + 4/3 - 4/3  = 0 - 4/3

 x² − 8x/3 = −4/3

Take half of the x term and square it  and  add the result to both sides

x² − 8x/3 + 16/9 = −4/3 + 16/9

Rewrite the perfect square on the left

(x − 4/3)² = −4/3 + 16/9

and combine terms on the right

(x − 4/3)²= 4/9

Take the square root of both sides

x − 4/3 = ±√4/9

Simplify  

x − 4/3 = ±2/3

Collect like terms

x = 4/3 ± 2/3

x = 4/3 + 2/3

x = 6/3

x = 2

Also:

x=4/3 − 2/3

which becomes

x = 2/3

Answer:

[tex]\frac{7}{4}[/tex] of a bag of soil

Step-by-step explanation:

Given: Mariah had [tex]2\frac{2}{4}[/tex] bags of soil to use in her garden. After her gardening, she had [tex]\frac{3}{4}[/tex] of a bag left

To find: quantity of soil used.

Solution:

Quantity of soil in the garden = [tex]2\frac{2}{4}=\frac{10}{4}[/tex] bags of soil

Quantity of soil left = [tex]\frac{3}{4}[/tex] of a bag

Quantity of soil used [tex]=\frac{10}{4}-\frac{3}{4}=\frac{7}{4}[/tex] of a bag of soil.

Answer:

The slope is 2/5 (0.4).

Step-by-step explanation:

The formula for finding a slope is m = (yB - yA)/(xB - xA). That equation becomes:

m = (9 - 7)/(5 - 0)

Subtract 7 from 9 to get 2.

m = 2/(5 - 0)

Any number subtracted by 0 equals itself.

m = 2/5, or 0.4 is the final answer.

Answer:

t(n)= 0.2 * 2ⁿ

Step-by-step explanation:

Thickness= 0.2 millimeters

paper = 1

n= number of folds

The exponential function will be given by

t(n)= 0.2 * 2ⁿ

so if there's a single fold

t(1)= 0.2 * 2¹

t(1)= 0.4 mm

Now for 2 folds the thickness will be

t(2) = 0.2 *2 ²

t(2)= 0.2 *4

t(2) = 0.8mm

The exponential that represents this scenario is

t(n)= 0.2 * 2ⁿ

And for 3 folds the thickness will be

t(3) = 0.2 *2 ³

t(3)= 0.2 *8

t(3) = 1.6 mm
