John and Sam have a lawn mowing service. At one home, John can mow the lawn by himself in 2 hours, but it takes Sam 2.5 hours. How many hours twill it take them to mow the same lawn
together? Give the answer correct to one decimal place.
Answer:
3/5 hours or 36 minutes
Step-by-step explanation:
John could mow three of these lawns in three hours (3/1 = three), while Sam could only mow two in three hours (3/1.5 = two). Therefore, the two of them could cut 5 lawns in 3 hours (3+2). Together, they can cut the same lawn in three and a half hours, or 36 minutes.
(8m-3n)(5m+9n) simplify
Answer:
40m² + 57mn - 27n²
Step-by-step explanation:
(8m - 3n)(5m + 9n)
each term in the second factor is multiplied by each term in the first factor, that is
8m(5m + 9n) - 3n(5m + 9n) ← distribute both parenthesis
= 40m² + 72mn - 15mn - 27n² ← collect like terms
= 40m² + 57mn - 27n²

A bicyclist rides 14 miles in 112 minutes. If she continues at this speed, how long will it take her to travel 35 miles? Answer quick hurry
Answer:
280 minutes
Step-by-step explanation:
The new distance travelled is 2.5 times larger than the previous (35/14 = 2.5), therefore, the new time needed to be travelled would also be 2.5 times larger than the original time taken.
[tex]112 \times 2.5 = 280[/tex]
Answer:
it will take her 280 minutes to travel 35 miles
Step-by-step explanation:
miles per hour = miles / hours
or in this case, miles / minutes
[tex]\frac{14 miles}{112 minutes}[/tex]
divide both the top and bottom by 112
[tex]\frac{0.125 miles}{1 minute}[/tex]
= 0.125 miles per minute
35 miles
[tex]35 / 0.125[/tex] = 280
280 minutes

Compute the derivatives at the given value of a
1) The derivative of the function g(x) = (3x - 5)/(x - 2) at a = 1 is; g'(1) = -1
2) The derivative of the function f(x) = √(3x - 4) at a = 2 is; 3/(2√2)
What is the Derivative of the Function?1) We want to find the derivative of the function g(x).
g(x) = (3x - 5)/(x - 2)
g'(x) = -1/(x - 2)²
Thus;
g'(1) = -1/(1 - 2)²
g'(1) = -1
2) We want to find the derivative of the function f(x).
f(x) = √(3x - 4)
f'(x) = 3/(2√(3x - 4))
f'(2) = 3/(2√(3(2) - 4))
f'(2) = 3/(2√2)

A cargo truck is traveling 70 miles per hour and plans to travel 840 miles, plus or minus 105 miles, depending on fuel levels. Fnd the minimum and maximum number of hours the truck will travel at that speed.
The minimum is 10.5 hours and the maximum is not 12.2 hours.
The minimum and a maximum number of hours the truck will travel at that speed are 10.5 and 13.5 hours respectively.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Average velocity = total distance / total time taken
Units of velocity are given by ⇒ meter/second
Speed of truck = 70 miles/hour
Maximum distance = 840 + 105 = 945 miles.
Minimum distance = 840 - 105 = 735 miles.
Now,
Time = distance / velocity
Minimum time = minimum distance / velocity
So,
Minimum time = 735 / 70 = 10.5 hour.
Maximum time = maximum distance / velocity.
Maximum time = 945 / 70 = 13.5 hour.
Hence "The minimum and a maximum number of hours the truck will travel at that speed are 10.5 and 13.5 hours respectively".

A sequence is defined recursively using the formula f(n+1)=-0.5f(n). If the first term of the sequence is 120, what is f(5)
Answer:
The sequence's fifth term is equal to 7.5.
Step-by-step explanation:
It is given in the question that A sequence is defined recursively using the formula f(n+1)=-0.5f(n) and we need to calculate f(5) if the first term of the sequence is 120.
Firstly,
The definition of a series is given by the formula f (n + 1) = -0.5 f. (n).
Now, what will be f(5) if the sequence's initial term is 120, let's calculate;
Recursively, a series is defined as follows;
=> f(n) = 120 if n = 1, otherwise.
Otherwise,
=> f(n) =-0.5f(n-1) if n > 1.
Now,
=> f(1) = 120
=> f(2) = -0.5f(1) = -0.5(120) = -60
=> f(3) = -0.5f(2) = -0.5(-60) = 30
=> f(4) = -0.5f(3) = -0.5(30) = -15
=> f(5) = -0.5f(4) = -0.5(-15) = 7.5
So, For n > 1, f(n) = (-0.5)(n-1) × 120
Therefore, the sequence's fifth term is equal to 7.5.
