If Susie paid 827 in taxes on gross income of 1748 what percent of her gross pay is being taken out in taxes

maw [93]

Answer:

47.3 % of Susie gross pay is being taken out in taxes .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\value\times 100}{Total\ value}$

If Susie paid 827 in taxes on gross income of 1748 .

Part value = 827

Total value = 1748

Putting all the values in the formula

$Percentage = \frac{827\times 100}{1748}$

$Percentage = \frac{82700}{1748}$

Percentage = 47.3 %

Therefore 47.3 % of Susie gross pay is being taken out in taxes .

The length of the diagonal of a square is 30square root 2 find the perimeter of the square

RoseWind [281]

Answer:

120.

Step-by-step explanation:

Using the Pythagoras theorem:

(30√2)^2 = x^2 + x^2 where x =length of each side of the square

1800 = 2x^2

x^2 = 900

x = 30.

So the perimeter = 4*30 = 120.

A hippopotamus's typical growth rate is typically 50.5% per year when considering it's weight in pounds from birth to maturity.

VARVARA [1.3K]

Answer:

9.3 years

Step-by-step explanation:

we know that

The equation of a exponential growth is equal to

$y=a(1+r)^x$

where

y is the weight in pounds

x is the number of years

a is the initial value or y-intercept

we have

$a=70\ lb\\r=50.5\%=50.5\100=0.505$

substitute

$y=70(1+0.505)^x$

$y=70(1.505)^x$

For y=3,100 lb

substitute in the equation

$3,100=70(1.505)^x$

solve for x

$\frac{310}{7} =(1.505)^x$

apply log both sides

$log(\frac{310}{7}) =log[(1.505)^x]$

$log(\frac{310}{7}) =(x)log(1.505)$

$x=log(\frac{310}{7})/log(1.505)=9.3\ years$

Why does the number 26 not belong with 17, 26, 44 & 65?

Sati [7]

Answer & Step-by-step explanation:

This is what is called an arithmetic sequence. An arithmetic sequence adds the same number every time. If we take and subtract the 3rd term from the 4th term, we get 21. However, when we subtract 17 from 26 or 26 from 44, we get 9 and 18 respectively, which is not in keeping with the sequence.
