Answer:

NCA = GRU

Step-by-step explanation:

Since triangle CAN = triangle RUG

This means

C=R

A=U

N = G

We can change the order of the letters for the triangle in the first, but then they have to be corresponding in the second

ANC = UGR

NCA = GRU

ACN = URG

CNA= RGU

In 1987, 522 comma 000 people worked in the air transportation industry. In 2003, the number was 480 comma 000. (a) Find a li

Answer:

the linear equation is :

y= -2625x+5737875

and 440000 employees will be in year 2271

Step-by-step explanation:

in order to find the linerar equation let us first convert the given data into (x,y ) co-ordinates i.e

x1= 1987 y1= 522,000

and

x2= 2003, y2 = 480000

according to two point form:

$y-y1 = (y2-y1) \frac{x-x1}{x2-x1}$

In this example we have x1=1987 , y1=522000 , x2=2003 and y2=480000. So,

$y - 522000 = \frac{480000-522000}{2003-1987} (x-1987)\\y- 522000 = -2625(x-1987)\\y- 522000= -2625x+5215875\\\\y= -2625x+5737875$

now to find the year when there will be 440000 employs working , we simply put y= 440000 in the above derived equation

$440000= -2625x+ 5737875\\\\2526x = 5737875 -440000\\2526x = 5736555\\x= \frac{5736555}{2526} \\x= 2271$

What is -0.18 as a fraction in simplest form.

Radda [10]

The answer is, 9/50
0.18 = 0.18/1
0.18/1 x 100/100 = 18/100
18/100 divided by 2/2 = 9/50
In conclusion the answer is 9/50.
Hopefully that helped! :)

Your friend Michelle just graduated and has two job offers that she is considering. Both job offers pay the same, but JobA

just olya [345]

Money offered to Michelle per annum in Job A = $1700

Number of years she will work in job A = 5

Percentage of earnings per annum for her retirement plan = 6.60%

Money she will earn will be the simple interest at the end of 5 years.

We know that :

$\color{plum}{ \tt{Simple \: interest = \frac{Principle \ \: \times \: Rate \: \: \times \: \: Time}{100} }}$

Principal = $1700

Rate = 6.60%

Time = 5 years

Which means :

$= \frac{1700 \times 6.60 \times 5}{100}$

$= \frac{56100}{100}$

$= \color{plum}\$561$

We also know that :

$\color{plum}\tt \: Amount = Principal + Interest$

Amount Michelle will earn at the end of 5 years for her retirement plan :

$= 1700 + 561$

$=\color{plum}\bold{\$ 2261}$

2261 can be rounded off to 2260.

Therefore, Michelle will earn <u>$2260</u> at the end of 5 years for her retirement plan.
