Answer:

Percentage profit= 33.33%

Step-by-step explanation:

Angela made $90000 income in 2004 then in 2005 she made income of $120000.

The percentage increase on her income will be determined by subtracting tge the initial profit from the final profit then dividing by the initial and multiplying by 100.

Profit= 120000-90000

Profit= 30000

Percentage profit=( 30000/90000)*100

Percentage profit= 1/3 *100

Percentage profit= 33.33%

Find the missing variable for a tralezoid. A=68^2 b= h=4 B=21

Bezzdna [24]

The answer is: " 2291 units " .
____________________________________________
Explanation:
____________________________________________
Formula for "Area of a trapezoid" :
____________________________________________
Area = (1/2) * (base length 1 + base length 2) * height;

or: A = (1/2) * (b + B) * h.

We are missing the value for "b" one of the base lengths.

However, since: A = 68² (given) ; B (the other base length) = 21; and the perpendicular height, "h" = 4 ; we can plug this values into the formula, and solve for "b" ;
________________________________________________
A = (1/2) * (b + B) * h ; ↔ 68² = (1/2) * (b + 21) * 4 ;

↔ 4624 = 2 (b + 21) = 2b + 42 ;

 ↔ 4624 = 2b + 42 ;

 ↔ 2b + 42 = 4624 ;

Subtract "42" from each side of the equation:

 2b + 42 - 42 = 4624 - 42 ;

to get: 2b = 4582 ;
___________________________________________________
 Now, divide each side of the equation by: "2" ; to isolate "b" on one side of the equation; and to solve for "b" ;
___________________________________________________
 2b / 2 = 4582 / 2 ;
___________________________________________________
to get: b = 2291 units.
___________________________________________________

Fill in Sin, Cos, and tan ratio for angle x. Sin X = 4/5 (28/35 simplified)

Fantom [35]

Answer:

Given: $\sin(x) = (4/5)$ .

Assuming that $0 < x < 90^{\circ}$ , $\cos(x) = (3/5)$ while $\tan(x) = (4/3)$ .

Step-by-step explanation:

By the Pythagorean identity $\sin^{2}(x) + \cos^{2}(x) = 1$ .

Assuming that $0 < x < 90^{\circ}$ , $0 < \cos(x) < 1$ .

Rearrange the Pythagorean identity to find an expression for $\cos(x)$ .

$\cos^{2}(x) = 1 - \sin^{2}(x)$ .

Given that $0 < \cos(x) < 1$ :

$\begin{aligned} &\cos(x) \\ &= \sqrt{1 - \sin^{2}(x)} \\ &= \sqrt{1 - \left(\frac{4}{5}\right)^{2}} \\ &= \sqrt{1 - \frac{16}{25}} \\ &= \frac{3}{5}\end{aligned}$ .
