Answer:

Step-by-step explanation:

It takes 4 hours to do task E using the route: start ⇒B⇒E

It will take 6 hours to do task E if using route : start ⇒C ⇒E

Taking the shortest route, it will take 4 hours

You can apply the critical path method to identify the shortest route possible. First , specify the activity and look for their dependencies.Using the activity diagram, establish the activity completion time.Finally, identify the critical path using the best case estimate.

The numerator of fraction is 1 less then its denominator if the numerator is increased by 5 the new fraction becomes equivalent

jek_recluse [69]

Answer:

4/5

Step-by-step explanation:

the numerator of fraction is 1 less than its denominator. If the numerator is increased by 4 and the denominator is increased by 5, the new fraction becomes equivalent to 4/5. what is the original fraction?

Let n = numerator

d = denominator

n = d - 1

$\frac{d - 1}{d}$

$\frac{d - 1 + 4}{d + 5}$ = $\frac{4}{5}$

$\frac{d + 3}{d+ 5}$ = $\frac{4}{5}$

cross multiply

5(d + 3) = 4(d + 5)

5d + 15 = 4d + 20

d = 5

n = d - 1

5 - 1 = 4

original fraction 4/5

The height (in feet) of punted football is a function of the time the ball is in the air. The function is defined by h(t) = - 7t

Kamila [148]

Answer:

The height of the football after 4 seconds is 80 feet.

Step-by-step explanation:

You know that the height (in feet) of punted football is a function of the time the ball is in the air and it is defined by:

h(t) = -7*t²+48*t

To calculate the height of the ball after 4 seconds, you must replace the time t by the time of 4 seconds:

h(4) = -7*4²+48*4

Solving, you get:

h(4) = -7*16+48*4

h(4) = -112+192

h(4)= 80

The height of the football after 4 seconds is 80 feet.
