Answer:

7 millimeters

Step-by-step explanation:

Volume is the area of the base times it's length.

140/10 is 14

so the area of the triangle is 14

the formula for area of a triangle is base times height divided by 2

so

d x 4/ 2 = 14

multiply both sides by 2

d x 4 = 28

divide both sides by 4

d=7

Joe can clear a lot in 2.5 hours. His partner can do the same job in 7.5 hours. How long will it take them working together?
irina [24]

Answer:

The time required by both persons to complete the work T = 1.458 hours

Step-by-step explanation:

Given data

Time required by Joe to clear a lot T_1 = 2.5 hours

Time required by his partner to clear a lot T_2 = 2.5 hours

Time required by both persons to complete the work by working together

T = \frac{T_1 T_2}{T_1 + T_2}

T = \frac{(2.5)(3.5)}{2.5 + 3.5}

T = 1.458 hours

Therefore the time required by both persons to complete the work T = 1.458 hours

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 : )
