The thickness of a block is approximately 2 centimeters. How many blocks are in a stack that is 1,000 millimeters high? ( 1 cm =
Andru [333]

Answer:

50 blocks

Step-by-step explanation:

First of all, you need to label you're proportions, which can be mm/blocks.

Then, for 1 block, it is 20 mm because the block is 2 cm, which is equal to 20 mm. So for you're proportion, it is 20 mm/1 block.

Finally, you need to find the total amount of blocks that equals 1000 mm. So you can multiply the 20 mm by 50 to get the 1000 mm. What you do at the top, you do at the bottom, so you also have to do 1 block by 50 to get 50 blocks

So for you're final answer/proportion, it is mm/blocks = 20/1 = 1000/50 and you're final answer is 50 blocks

Hope this helps : )

What is the slope between (14,-8) and (7,-6)
djyliett [7]

Answer:

-  \frac{2}{7}

Step-by-step explanation:

Slope formula:

\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

Slope

=  \frac{ - 8 - ( - 6)}{14 - 7}

=  \frac{ - 8 + 6}{7}

=  -  \frac{2}{7}
