C=1/2e•n solve for e

Answer:

The value of y is 18 at x = 70

Step-by-step explanation:

The equation of the directly proportional is y = k x, where k is the constant of proportionality.

∵ The value of y is directly proportional to the value of x

→ By using the equation above

∴ y = k x

∵ x = 140 and y = 36

→ Substitute them in the equation above

∴ 36 = k(140)

∴ 36 = 140k

→ Divide both sides by 140

∵ [tex]\frac{36}{140}[/tex] = k

∴ [tex]\frac{9}{35}[/tex] = k

→ Substitute the value ok in the equation

∴ y = [tex]\frac{9}{35}[/tex] x ⇒ equation of proportionality

∵ x = 70

→ Substitute in the equation to find y

∴ y =  [tex]\frac{9}{35}[/tex] × 70

∴ y = 18

∴ The value of y is 18 at x = 70

Step-by-step explanation:

We have (n + 2)/5 = 14.

=> (n + 2) = 14 * 5 = 70 (multiply 5 on both sides)

=> n = 70 - 2 = 68. (subtract 2 on both sides)

Hence the number n is 68.

Answer:

  60 feet

Step-by-step explanation:

We always assume that the shadow length is proportional to the height of the object casting the shadow. So, we have ...

  height/shadow = b/(72 ft) = (5 ft)/(6 ft) . . . let b represent the unknown height

  b = (72 ft)(5/6) = 60 ft . . . . . multiply by 72 ft

The building is 60 feet tall.

Answer:

The strategy that his financial advisor may suggest is:

Shift his portfolio to a more moderate approach.

Step-by-step explanation:

The strategy that got Ronald to this position must have been a high-risk portfolio.  Therefore, his adviser should convince him to pursue a more moderate approach to reduce the losses and ensure recovery.  However, it is known that high-risk investments attract higher returns than moderate-risk investments.  The loss exposure that Ronald has experienced lately may also be cyclical, in which case, it may be more prudent to maintain a long position, as recovery will soon be on the corner.

Answer: A- shift his portfolio to a more moderate approach

Step-by-step explanation:

It’s a simple strategy

Answer: Yes

Step-by-step explanation:

Given that:

Number of employees (n) = 6

Number of employees who can work at a time (r) = 3

To know of its possible for different groups of employees to work for two wweka, then, the number of different groups or combination must be greater Than or equal to 14 (two weeks) ; Assume (1 week = 14 days)

Using the combination formula :

nCr = n! ÷ (n - r)!r!

6C3 = 6! ÷ (6 - 3)!3!

6C3 = 6! ÷ 3!3!

6C3 = (6*5*4) ÷ (3*2*1)

6C3 = 120 / 6

6C3 = 20 ways

Hence, 20 different groups of 3 employees can be made from all 6 employees. Hence, it is possible to have different groups work for two weeks

Answer:

with what but make me brainllest

Step-by-step explanation:

Answer:

450:155 min

450/150.75=2.98

155 x 2.98=462.69 minutes

=7 hours 43 minutes

-1/5 (x - 4) = -2

(-1/5)x + (4/5) = -2    

-2 can be turned into -10/5

(-1/5)x = (-10/5) - (4/5)

(-1/5)x = -14/5

multiply by -5 on both sides

x = 14
