Find the exact value of the expression: -6 3/5 - (-7 4/15) + 2 1/5

The Magnititude of -3 + 4i is 5.

Answer: -b - 9

Step-by-step explanation:

First, since the a cancel eachother out we are left with (4-b) + (-6-7)

Second, you want to add the -6 and -7 to get -13, so (4-b) - 13

Finally, add the 4 to the negative 13 to get (-b - 9)

Hope this helps.

Answer:

4.62 years

Step-by-step explanation:

Half the car's value =>$24,000/2 = $12,000

The formula for exponential decrease =

y = a(1 - r)^t

y = Initial value = $24,000

a = Value after time t = $12,000

r = Decrease rate = 15% = 0.15

t = time in years =??

Hence,

24,000 = 12000 ( 1 - 0.15)^t

Divide both sides by 12000

24000/12000 = 12000 ( 0.85)^t/ 12000

2 = 0.85^t

We take the logarithm of both sides

log 2 = log (0.85)^t

log 2 = t log 0.85

Divide both sides by log 0.85

t = log 2/log 0.85

t = 4.62098120373 years

Approximately = 4.62 years

It would take 4.62 years to be worth half the initial price

Answer:  [tex]\$1100[/tex]

Step-by-step explanation:

Given

Principal amount is [tex]P=\$4000[/tex]

Rate of interest [tex]R=5\%[/tex]

Time period [tex]T=5\ yr\ \text{and}\ \text{6 months}\equiv 5.5\ yr[/tex]

We know, Simple interest is

[tex]\Rightarrow S.I.=\dfrac{P\times R\times T}{100}[/tex]

Putting values

[tex]\Rightarrow S.I.=\dfrac{4000\times 5\times 5.5}{100}=\$1100[/tex]

Sara gets [tex]\$1100[/tex] after 5 years and 6 months

120/1500=x/100, x=8

So, you make 8% commision, meaning you now have to do this:

x/1300=8/100, so x=$104

Your question has confusing details. So, I will rephrase as:

How many 2' x 4' would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?

Answer:

12.5 plates

Step-by-step explanation:

Given

Building dimension:

[tex]Length = 25ft[/tex]

[tex]Width = 50ft[/tex]

Plates

[tex]Length = 2ft[/tex]

[tex]Width= 4ft[/tex]

To do this, we have to divide the dimension of the building by the dimension of the plates

So, we have:

[tex]n = \frac{Length\ of\ Building}{Length\ of\ Plates}[/tex]

and

[tex]n = \frac{Width\ of\ Building}{Width\ of\ Plates}[/tex]

For the length, we have:

[tex]n = \frac{25}{2}[/tex]

[tex]n = 12.5[/tex]

For the width, we have:

[tex]n = \frac{50}{4}[/tex]

[tex]n = 12.5[/tex]

So, 12.5 of the plates are needed

Answer:

B

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 26 and h = 5 , then

A = [tex]\frac{1}{2}[/tex] × 26 × 5 = 13 × 5 = 65 ft² → B

Answer:

1/15

Step-by-step explanation:

Given that:

Total Number of M&M's = (4 + 1 + 3 + 2) = 10

Number of yellow M&M's = 3

Probability = required outcome / Total possible outcomes

First pick (choosing without replacement)

P(choosing a yellow M&M) = 3 / 10

Second pick :

P(choosing a yellow M&M) = 2 / 9

P(choosing 2 yellow M&M) = 3/10 * 2/9 = 6/90 = 1/15
