Answer:

36 inches?

Step-by-step explanation:

6 feet x 6 inches in depth = 36 inches?

6 feet by 6 inches in depth

9514 1404 393

Answer:

  y = -3/2x +11

Step-by-step explanation:

The slope of the parallel line is the same as the slope of the given line, so ...

  m = -3/2

The y-intercept of the parallel line can be found from ...

  b = y -mx

  b = 5 -(-3/2)(4) = 11

So, the desired equation is ...

  y = mx +b

  y = -3/2x + 11

_____

Additional comment

Since you know the slope and a point on the desired line, you can write down the equation directly using the point-slope form. No additional math is required.

  y -5 = -3/2(x -4)

Answer:

x - 13 = 13 - x

Step-by-step explanation:

The commutative property of addition is a+b=b+a

The third equation is the only one not following the rule. It states that a-b=b-a, whoich is not true.

For exaple, 2-1 is not equal to 1-2.

Answer:

15.3 m/s

Step-by-step explanation:1) Find the gravitational potential energy using the equation :

     [tex]PE_g=mgh[/tex]

    [tex]PE_g=2.5(12)(9.8)\\PE_g=294[/tex]

2) Then use the equation for kinetic energy to solve for the velocity:

     [tex]KE=\frac{1}{2} mv^{2}[/tex]

     [tex]294=\frac{1}{2}(2.5)(v^2)\\235.2=v^2\\\sqrt{235.2} =v\\15.3 m/s=v[/tex]

Answer:

5x^2-4+4(x^2)-6x

Step-by-step explanation:

first you need to remove the unnecessary parentheses it should look like this: 5x^2-7-(4(x^2)+6x-3)

then you should calculate the sum it should look like this: 5x^2-4+4(x^2)-6x and that is your answer

Step-by-step explanation:

Answer:

32 Square centimeters

Step-by-step explanation:

You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.

Answer: 2 1/2kg

Step-by-step explanation:

Weight of plant food bought = 4 1/2kg

Amount used on strawberry plant = 1 2/3kg

Amount used on tomato plant = 1/4kg

Therefore, the amount used will be:

= 1 2/3 + 1/4

= 1 8/12 + 3/12

= 1 11/12kg

We then subtract the value gotten from the amount bought. This will be:

= 4 1/2 - 1 11/12

= 4 6/12 - 1 11/12

= 2 6/12

= 2 1/2kg

Step-by-step explanation:

Answer: there were 12 chocolates in each box. (Originally, before any got eaten)

Step-by-step explanation: let x represent the total amount of chocolates in each box.

8x - 3(8) = 72

8x - 24 = 72 add 24 to both sides

8x = 96 divide both sides by 8

X = 12

Answer:

That means you had 48 chocolates in each box

Step-by-step explanation:

Since you eat 3 chocolates from all 8 boxes, you do this:

8 x 3 which = 24

Now since you have 72 chocolates left you do this:

72 - 24 which = 48

So, therefore, there were originally 48 chocolates in each box

(Don't eat so much chocolate lol you could get sick)
