Answer: 375
Step-by-step explanation:
Since we are given the information that there are 250 bricks used to build a wall 20 feet high, the number of brick used per feet will be:
= 250/20
= 12.5 bricks per feet.
Therefore, the number of bricks that will be used to buld a wall that is 30 fet high will be:
= 12.5 × 30
= 375 bricks.
Therefore, 375 bricks would be used.
All you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)
<span>True A.)
It is the longest side of a right triangle.
False B.) It is one of the legs.
It is opposite the right angle.
False C.) Its length is the sum of the lengths
of the other two sides.
False D.) It forms a right angle with an adjacent
side.
If option B is a single choice, then it has to be called false.
Look at option B.
B. "It is one of the legs" is false.
"It is opposite the right angle" is true.
Are you sure option B. is not two different choices, and there are really 5 choices instead of 4?

Wow what grade are you in that seems hella confusing!! I feel bad for you!
Answer:
3 1/5 ft
Step-by-step explanation:
We can set up a proportion:
, where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
