We add all these mixed numbers together:
1 1/2 + 2 3/4 + 2 1/3
It will be easier to convert the mixed numbers into improper fractions:
3/2 + 11/4 + 7/3
Now we have to find the common denominator which is 12:
18/12 + 33/12 + 28/12 = 79/12 = 6 7/12
The answer is 6 7/12 hours.
Answer: 45 minutes
Step-by-step explanation:
the first pump takes care of 300 gallons so we need to worry about the remaining 900 gallons. the second pump removes 20 gallons per minute so all u have to do to find how many minutes it would take is divide 900 gallons by 20 gallons a minute which gives you 45
it will take 45 minutes to completely drain the pool
Answer:
Option D is the answer : 8.8 * 10^-5
Answer:
g(x)=10x-30 when x is 1
g(x)=-20. hence dats is d first function
g(x)=-20x+5
g(x)=-15 hence dats d second function
Answer:
Step-by-step explanation:
That composite figure is made up of a square and a quarter of a circle. We will first find the area of the square. Then we will find the area of the circle and divide it by 4.
Area of square = 1.6 × 1.6
Area of square = 2.56 m squared
Area of circle = (3.14)(1.6²) In case you forgot, the area of a circle is A = πr².
Area of circle = 8.0384
Divide that by 4 to get 2.0096.
Add 2.0096 to 2.56 to get the total area, which is
4.5696 or 4.6 rounded (choice D)
