Answer:
A=168 ft²
Step-by-step explanation:
18×8=144
0.5*8*6=24
24+144=168
Here are the coordinates :)
Answer:
The answer is: 1. 5 minutes and 2. 133.3 meters
Step-by-step explanation:
To find how long it takes the cyclist to travel 2km at 24km / hour, set up the equation and cross multiply:
2 / 24 = x / 1
24x = 2
x = 2/24 = 1/12 of an hour or 60 / 12 = 5 Minutes.
To find how far he travels in 20 seconds:
Multiply 24 km by 1000 to get meters per hour. Divide by 3600 to get meters per second:
24000 / 3600 = 6.6 meters per second.
Multiply by 20 seconds to get the distance traveled in 20 seconds:
6.6 * 20 = 133.3
The answer is 225.19 mm since you convert the 11.2 cm to mm which is 112mm and then use the equation pi x r^2 x h
Answer:
It takes <u>8 4/7 </u>days for both bricklayers to build the wall together.
Step-by-step explanation:
The first bricklayer takes 15 days to build the wall, which means it builds 1/15 of the wall per day.
The second bricklayer takes 20 days to build the wall, which means it builds 1/20 of the wall per day.
So if they build the wall together, the expression below will tell how much of the wall they build per day together.
1/15 + 1/20
To add the fractions, we must find a common denominator, which is 60.
4/60 + 3/60, which equals 7/60.
So, they can build 7/60 of the wall per day together. How many days will it take them? We must find how many times 7 fits into 60, which can be done by solving 60/7, which is 8 4/7.
So, it takes 8 4/7 days for both bricklayers to build the wall together.
