Enter your answer as a decimal in the box.

Answer:

2 different ways

Step-by-step explanation:

You are looking at the factors of 60.

1×60 does not work, too many pictures in a row.

2×30 does not work, too many pictures in a row.

3×20 THIS WORKS!

4×15 THIS ALSO WORKS!

5×12 Nope, too many rows

6×10, no, too many rows

So there's just two ways to arrange the pictures.

Answer:

Slope = -1

Step-by-step explanation:

We will use 2 points from the graph.\

(0 , 2) and (2 , 0)

formula for slope = y2 - y1/x2 - x1

0 - 2/2 - 0

=-2/2

=-1

Answer:

y = -2x + 9

Step-by-step explanation:

slope intercept form : y = mx + b

where m = slope and b = y intercept

first let's find the slope

slope formula :

[tex]m = ( \frac{y2 - y1}{x2 - x1} )[/tex]

where the x and y values are derived from the given points

here we are given (2,5) and (6,-3)

(x1,y1) = (2,5) so x1 = 2 and y1 = 5

(x2,y2) = (6,-3) so x2 = 6 and y2 = -3

we now plug these values into the formula

recall formula

[tex]m= ( \frac{y2 - y1}{x2 - x1} )[/tex]

plug in x1 = 2, y1 = 5, x2 = 6 and y2 = -3

m = (-3 - 5) / ( 6 - 2 )

m = (-8)/(4)

m = -2

the slope is -2

now to find the y intercept we plug in the slope and the x and y value of a given point into slope intercept form and solve for b

y = mx + b

given point : (2,5) x = 2 , y = 5, m = -2

5 = -2(2) + b

5 = -4 + b

9 = b

so the equation would be y = -2x + 9

Answer:

y = - 7

Step-by-step explanation:

Since the solution is always the same for y, y equals that solution and does not depend on x.

Answer:

56000 square yards

Step-by-step explanation:

I hope it helps you!!!

Rewrite the equation in slope- intercept form.

3(y-1) = 2x + 2

Use the distributive property

3y-3 = 2x + 2

Add 3 to both sides

3y = 2x + 5

Divide both sides by 3

Y = 2/3x + 5/3

Slope = 2/3

Answer:

No, a polygon cannot have a decimal number of sides.

Explanation:

using the formula:

14 = 360 ÷ number of sides

1/number of sides = 14/360

number of sides = 360/14    

number of sides = 25.71428571    

Answer:

all polygons have exterior angles that totL to 360 degrees from triangles to 20-gons. so 360 divided by 14 is 25.71 sides which is not possible because what would .71 of a side look like....now this is assuming that you were referring to regular polygon with all sides the same. I suppose you could gave a polygon with a whole number of sides but the relationship between the exterior angles could be such that not all of the angles have the same degree measure. I would say that an exterior angle for any polygon would need to be greater than 0 but less than 360. so my answer is yes it could be possible le

Answer:

7 hours

Step-by-step explanation:

12hrs=1116kms

1hr=1116÷12

1hr=93kms

Xhrs=651kms

Xhrs=(651÷93) ×1

=7×1

=7hrs

Answer:

80°

Step-by-step explanation:

the triangles are symmetrical. therefore their angles will be equal.

interior angles of a triangle = 180°

180° - 30° - 70° = m<D

80° = m<D

Answer:

$8000

Step-by-step explanation:

With the provided values you get the equation

1800+.15x=3000

with x being the amount of sales he needs

1. 3000-1800=1200

gives 1200=.15x

2. 1200/.15 = 8000

so x = 8000

Answer:

Answer:

6 of the 30 apples are green

6 / 30 = .2

So 20% of the apples are green.

Percentage of the apples are green is 20%

"A Percentage is a number or ratio that represents a fraction of 100. It is often denoted by the symbol %".

According to the question

Total Apples = 30

Red Apples = 24

Green Apples = 6

Percentage of the apples are green = [tex]\frac{6}{30}[/tex]×[tex]100[/tex]

= [tex]20[/tex] % or [tex]0.2[/tex]

∴ Percentage of the apples are green is 20%.

Answer: Yellow option

Step-by-step explanation:

The points noted are (0,-2) and (3,-1)

So the slope is (-2--1)/(0-3) = -1/-3 = 1/3

So options blue, green and red are out.

So the only option is yellow

Answer:

It's 5

Step-by-step explanation:

-4x+5=-15 (subtract 5)

-4x=-20 (divide by -4)

x=5

Step-by-step explanation:

Work backwards. First, create a function:

f(x) = x

First, instead of adding 5, subtract it:

f(x) = x - 5

Then, divide by -4:

f(x) = (x - 5) ÷ -4

Then plug in -15:

f(-15) = (-15 - 5) ÷ 4

= -20 ÷ -4

= 20 ÷ 4

= 5
