Answer:
The answer to your question is: three hours.
Step-by-step explanation:
data
Jogger 1 = 6 mi/h
Jogger 2 = 6.5 miles/h , starts 15 min (0.25 h) after the first Jogger
Time when the second jogger catch the first jogger = ?
Process
Advantage of the first jogger d = vt = 6(0.25) = 1.5 mi
Distance where they meet 1.5 + 6t = 6.5t
Find the t value 6.5t - 6t = 1.5
0.5 t = 1.5
t = 1.5 / 0.5
t = 3 hours
Answer:
A
Step-by-step explanation:
You would first subtract 6x from both sides which will give you something like:
-4= 2x - 9
then you would add 9 on both sides which would give you
5 = 2x
which now you would divide 2 by both sides with would give you
5/2 = x
simplify it one more time
2.5 = x
Answer:
To find the inverse, interchange the variables and solve for y
f^−1(x)=−7x+7

Answer:
The correct answer is 10 units.
Step-by-step explanation:
Profit function of a small business is given by P(x) = 0.3 + 7x - 40, where x is the number of units sold.
The small business intend to make a profit of $60.
To find out the number of units the business has to sell in order to have a profit of $60 is given by,
P(x) = 0.3 + 7x - 40 = 60
⇒ 0.3 + 7x - 100 = 0
⇒ 3 + 70x - 1000 = 0
⇒ x = -70 ± ×
⇒ x = -70 ± 130 ×
⇒ x = 10 or -
Quantity sold cannot be negative giving us the value of x as 10 units.
Answer:
V= 125.6
Step-by-step explanation:
The equation is V=Bh
Since there is a circle you would substitute B for (3.14 x r^2)
V= (3.14 x r^2)(h)
= (3.14 x 4 )(10)
=12.56 X 10
V =125.6
