6/24 is 25 percent...... so 25% of his apples are bad.
Answer:
805.5 out of 900
Step-by-step explanation:
A test is out of 100 and because there are 9 tests: 9 x 100 which equals 900.
To get the average we add up each test mark and divide by the number of tests. The same can be applied here but reversed. So because there were 9 tests we can multiply 89.5 by 9 which gives us 805.5. Beverly scored 805.5 marks out of 900 which makes her average 89.5% for 9 tests.
Answer:
A
Step-by-step explanation:
To multiply powers of a variable, add the exponents:
This rule works for all exponents, positive, negative, or zero. Also, remember that 
.
Also, remember the definition of negative exponent: 
To multiply the two monomials, start by multiplying the coefficients, 14 and 4. That gives 56, so your answer begins with 56.
Now for the powers of x, 
For the powers of y, 
Your answer is
Answer:
Volume of cylindrical tank is 2122.64 cubed feet.
Step-by-step explanation:
It is given that:
Radius of cylindrical tank = 6.5 feet
Height of tank = 16 feet
Volume of tank = πr²h
Putting the values in the formula
Volume = 3.24 * (6.5)² * 16
Volume = 3.14 * 42.45 * 16
Volume = 2122.64 cubed feet.
Therefore,
Volume of cylindrical tank is 2122.64 cubed feet.
A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
