Answer:

First photo, I think they are all the same

Second, see below

Step-by-step explanation:

Numbering is by the numbers next to the problem, not the order of the photos

(2) Biggest area

[] Find alllll the areas and compare! Area is base x height divded by 2

[] A

2 x 4 / 2

8 / 2

[] B

2 x 4 / 2

8 / 2

[] C

2 x 4 / 2

8 / 2

[] D

2 x 4 / 2

8 / 2

Now, I think this is a trick question and they are all the same areas. I am not 100% sure, but if you do the math that is what you get :)

(1) Drawing heights

[] The height is from the middle of the base to the point across. For the one on the left you would find the of the base and draw a straight line into the corner across from it at the bottom right.

[] The one on the right would be the same, but it would go into the narrower corner on the top

(Hopefully this helps and is correct! Have a nice day :D)

Lizette wanted to see if it would be possible to use a little less materials in a tea infuser but still not be required to be at

Considering the volume of a rectangular prism, since the new volume is greater than the filled volume, the new dimensions would work, and 90.29% of the infuser would be filled.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism of length l, width w and height h is given by:

V = lwh.

The original dimensions are:

h = 7.9 cm, l = 3 cm, w = 1.5.

Hence the volume in cm³ was:

V = 7.9 x 3 x 1.5 = 35.55 cm³.

The infuser was filled to 80% capacity, hence:

Vf = 0.8 x 35.55 = 28.44 cm³.

For the new dimensions, we have that h = 7 cm, hence the volume is:

Vn = 7 x 3 x 1.5 = 31.5 cm³.

28.44/31.5 x 100% = 90.29%.

Since the new volume is greater than the filled volume, the new dimensions would work, and 90.29% of the infuser would be filled.

Solve |5x+30|=10x ......

Orlov [11]

Answer:

Option A

Step-by-step explanation:

We need to solve out ,

$\implies |5x + 30| = 10x$

We can write it as ,

$\implies 5x + 30 = \pm 10x$

On simplyfing further,

$\implies 5x + 30 = 10x \quad or \quad 5x +30=-10x$

On solving the above equation , we will get ,

$\implies \boxed{ x = 6,-2}$

Now we know that the value of modulus is never negative so when we will put x is equal to 2 on the RHS we will get -20 which is not possible . Therefore , the extraneous root is -2 .

Option A is correct .
