There are approximately 4.3 weeks in each month. How much will you take home each month after taxes?​
Marianna [84]

Answer:

So roughly c x c = b/100

5 x 5 x 100 = $2500

Step-by-step explanation:

Lets say c = 5 and b = 1

= 5c =100c/5c x b

= 20c x b

We can also show

= 20c x b =5c

c = 20c/5c x b = 5c

1/20 x 5c = 5c

b=1

One example is 20%  = 0.20 x 500 = 100c  

=  7.12c  = 7c

1= 100%

100 x 71.042  = 710.42 weekly pay. emergency tax 142 = 568

100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107

710-107 = 603 a week

4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29

Mr. Soto plans to open a savings account. Four banks offer the annual interest rates shown. Which list shows these interest rate
Delvig [45]
Ok, so IDK if I'm about to do this problem right, but here we go;


so first, lets change these all to decimals (I more of a decimal gal)

3 1/2 = 3.5
3 2/3 = 3.6666 (repeating)
3 3/5 = 3.6
3 3/8 = 3.375

So now, just order them from greatest to least.  

3.66666, 3.6, 3.5, 3.375.  

Now, change them back to fractions.  
3 2/3, 3 3/5, 3 1/2, 3 3/8


So, if I'm correct, the answer is 3 2/3%, 3 3/5%, 3 1/2%, 3 3/8%
Hopefully I solved your problem!

Right triangle XYZ is shown. Y (2,6) (1, 2) 6 х 7 Z Rounded to the nearest hundredth of a unit, what is the length of the hypote
Dmitriy789 [7]

Answer:

8.12

Step-by-step explanation:

We obtain the distance between x and y

d = sqrt[(x2 - x1)² + (y2 - y1)²]

d = sqrt[(1 - 2)² + (2 - 6)²]

d = sqrt[1 + 16)

d = sqrt(17)

d² = 17

From Pythagoras rule;

Hypotenus = sqrt(Adjacent² + opposite²)

Hence,

Hypotenus = sqrt(17 + 7²)

Hypotenus = sqrt(17+ 49)

Hypotenus = sqrt(66)

Hypotenus = 8.124

Hypotenus = 8.12
