Answer:
730
Step-by-step explanation:
separate each rectangle
use the formula to calculate the area of each rectangle.
1st rectangle
area = length ×breadth
length =5, breadth =8+25+8=41
A1=5×41=205
2nd rectangle
A2=8×25=200
....
A3=5×25=125
A4=8×25=200
Add all As and you have your ans 730
Answer:
≈ 6360 m³
Step-by-step explanation:
Volume of a cylinder = πr²h
radius = 12 m, h= 42.2 m
Therefore; V = 3.142 × 12² × 42.2
= 19093.3056 m²
Since the tank 1/3 full of water;
Volume = 1/3 × 19093.3056 m³
= 6364.4352 m³
≈ 6360 m³
Given: 2/3 every 30 seconds
If we cut 2/3 in half, we get 1/3. This would also mean we cut the time in half 30 / 2 = 15 seconds
Therefore, 1/3 of the length every 15 seconds.
15 + 15 + 15 = 45 seconds to go the full length of the path
Answer:
children's: 111 and adults: 62
Explanation:
- given total number of people 173
- total amount received is $306
- during the process, we shall consider x as children and y as adult
make equations:
x + y → 173 [ this was from total people ]
1.5x + 2.25y → $306 [ this was from cost ]
try to make x the subject:
x + y → 173
x → 173 - y ______equation 1
1.5x + 2.25y → $306
1.5x → 306 - 2.25y
x → 
__________equation 2
solve them simultaneously:
= 173 - y
306 - 2.25y = 259.5 - 1.5y
-2.25 + 1.5y = 259.5 - 306
-0.75y = -46.5
y = 62
so there were total 62 adults that day in the public swimming pool.
find children's using:
x → 173 - y
x → 173 - 62
x → 111
so there were total 111 children's that day in the public swimming pool.
One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?
- Observing the trends in prices.
- Observing Demand and supply curve.
<h3>Contrast the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets.</h3>
The difference that exist between a rise in price due to the inflation and a rise in price due to microeconomic markets is based on the price changes that has occurred in terms of demand and supply model.
Note that this is said to be the price in a given market but the price rise as a result of to inflation tells that the price rise is one that reaches a lot of markets and not only just one market.
Hence, One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?
- Observing the trends in prices.
- Observing Demand and supply curve.
