A person is to install five devices each 6 7/8 inches wide with 3 1/2 inches between switches. how much space will be needed to

solong [7]

Refer to the diagram shown below.

w = 6 7/8 in = 6.875 in, the width of each device.
d = 3 1/2 in = 3.50 in, the space between teo devices.

The total space needed is
D = 4(w+d) + w
= 5w + 4d
= 5*6875 + 4*3.5
D = 48.375 in or 48 3/8 in

Answer: 48 3/8 inches or 48.375 inches

Cerra Co. expects to receive 5 million euros tomorrow as a result of selling goods to the Netherlands. Cerra estimates the stand

Jlenok [28]

Answer:

$58,075

Step-by-step explanation:

Given:

Expected amount to be received = 5 million euros

Standard deviation of daily percentage change of euros, σ = 1%

Confidence level = 95%

Expected percentage change of the euro tomorrow = 0.5 percent

let,

the current spot rate of the euro (before considering the maximum one-day loss = $1.01

Now,

The maximum one-day percentage loss

= Expected change of euro - 1.65 × σ

(here 1.65 is constant for 95% confidence)

= 0.5% - 1.65 × 1%

= -1.15% (Here negative sign depicts the loss)

Therefore,

maximum one-day loss in dollars

= maximum one-day percentage loss × Exchange rate × Amount to be received

= -1.15% × $1.01 × 5 million euros

= -0.0115 × 1.01 × 5,000,000

= -$58,075 (Here negative sign depicts the loss)

Johnny has $100 in the bank and plans to deposit $15 per day. Sal has $250

ICE Princess25 [194]

Answer:

6 days

Step-by-step explanation:

First we have to write an expression that represents Johnny's and Sal's banking plans.

Johnny: He has an initial value of $100 and that value will increase by $15 every day. So the expression looks like: 15x + 100, where x is the amount of days it's been.

Sal: An initial value of $250 and the value will decrease by $10 everyday. The expression looks like: -10x + 250, where x is the amount of days it's been.

To find how many days they have until they have the same amount of money in the bank, we can set the expressions equal to each other and solve for x:

15x + 100 = -10x + 250

Add 10x to both sides to isolate the x on one side of the equation:

25x + 100 = 250

Subtract 100 from both sides of the equation to isolate 25x:

25x = 150

Divide both sides by 25 to find the value of x:

x = 6

Since x represents the amount of days it's been, x = 6 means that it will take 6 days for their bank accounts to have the same amount of money in them.

Hope this helps :)

Find the perimeter of the triangle shown.Simplify your answer.Show all your work.

VashaNatasha [74]

Answer: 12 sqrt(5)

Explanation:
First simplify:
= Sqrt(45)
= sqrt(9*5) sqrt of 9 is 3 so bring out 3
= 3sqrt(5)

= 2sqrt(20)
= 2sqrt(4*5) sqrt of 4 is 2 so bring that out and multiply it by 2
= 4sqrt(5)

= 5 sqrt(5) is already simplified

= 3sqrt(5) + 4 sqrt(5) + 5sqrt(5)
= 12 sqrt(5)
