Answer:
The height of the wall is 2.7 m.
Explanation:
The number of blocks required = 2450. Each cubical block has a side of 20cm(0.2m).
But, volume = length × width × height.
So that,
the volume of each block = (0.2 × 0.2 ×0.2)
= 0.008
The total volume of the blocks to be used = 2450 × 0.008
= 19.6
The window has a measurement of 2.5m ×1m;
its space volume = 2.5m ×1m × 0.4m
= 1.0
The door has a measurement of 2m× 3m;
its space volume = 2m× 3m × 0.4m
= 2.4
Thus, the window space and door space has a volume = 1.0 + 2.4
= 3.4
Total volume of the wall = length × width × height
⇒ The total volume of the blocks - the window space and door space volume = length × width × height
The wall to be constructed has a length of 15m and width 40cm (0.4m).
So that the height could be determined as,
19.6 - (3.4) = 15m × 0.4m × height
16.2 = 6 ×height
⇒ height =
height = 2.7 m
Therefore, the height of the wall is 2.7m.
Answer:
d. a homogeneous; a downward-sloping
Explanation:
The monopoly is a market structure where there is a single bidder of a certain good or service, that is, a single company dominates the entire supply market, and there is a homogeneous product or there are no nearby substitutes. When there is a monopoly in a market, there is only one company capable of offering a product or service that does not have close substitutes.
The monopoly faces a negative slope demand curve: depending on the price set buyers will demand more or less.
"In September 1786, at the Annapolis Convention, delegates from five states called for a Constitutional Convention in order to discuss possible improvements to the Articles of Confederation. The Constitutional Convention took place in Philadelphia on May 14, 1787."
The answer is D which is physics and computer science
Trade and commerce increase in the Europe during the Middle ages caused effective development of towns and cities. Medieval cities were made possible because of productivity, trade, exchange of products and money. Most businesses nowadays like companies and banks which store the money made in countries had their fair share of history that rooted in the Middle ages.
This is the answer I got from another Brainly user by the name of "Hagrid".
