Answer:

sine A = four-fifths

Step-by-step explanation:

You have a rectangle triangle ABC with hypotenuse AB 35, side CB 28 and side CA 21. The angle C is 90°.

tanA =5\12

As

tanA = opposite\adjacent

= BC\AC

= 5\12

Answer:

Length of rectangle = 16 cm

Width of rectangle = 4 cm

Step-by-step explanation:

Given:

Area of rectangle = 64 cm²

Find:

Length and width

Computation:

Assume;

Length of rectangle = a

So,

Width of rectangle = a -12

Area of rectangle = l x b

So,

a(a-12) = 64

a² - 12a - 64 = 0

a² - (16-4)a - 64 = 0

a² - 16a+ 4a - 64 = 0

a (a-16) + 4(a-16)= 0

(a-16)(a+4) = 0

a= 16 , a = -4

So,

Length of rectangle = 16 cm

Width of rectangle = a -12

Width of rectangle = 16 -12

Width of rectangle = 4 cm

Answer:

$500

Explanation:

If Joe saved 60% of the cost, given that the amount he saved was $300, to find the total cost of the computer, we need to know 100% of the cost.

60% = $300

[Set the percentage to a fraction and let x be the total cost]

(60/100) x = $300

60x / 100 = $300

_____________

60 → 30 × 2 → 15 × 2 × 2 → 5 × 3 × 2 × 2

______________________________

100 → 50 × 2 → 10 × 5 × 2 → 5 × 2 × 5 × 2

_______________________________

5 × 3 × 2 × 2 / 5 × 2 × 5 × 2 =

3 / 5.

_____________________________

3x / 5 = 300

3x / 5 × 5 = 300 × 5

3x = 1500

Answer:

b 25

Step-by-step explanation:

Answer:

(a) AC = 12.565 m

(b) bearing of C from A is 90°

(c) BT = 9.373 m

Step-by-step explanation:

(a) extend North line down & perpendicular to AC.

Call that perpendicular intersection "P".

∠BAC = 90° - 53° = 37°

cos 37° = AP/15

0.7986 = AP/15

AP = 11.979 m

∠PNC = 180° - 161° = 19°

∠BCP = 90° - 19° = 71°

18 cm = 0.18 m   (red flag note: 18 cm looks very out of scale for the picture)

cos 71° = CP/0.18

0.3256 = CP/0.18

CP = 0.586 m

AC = 11.979 + 0.586 = 12.565 m

(b) The bearing to C from A is 90°

(c) tan 58° = 15/x

1.6003 = 15/x

x = 9.373 m

Step-by-step explanation:

2 + 3 + 5 = 10 units

30,000/10 = 3,000 per unit

2 units = 2 x 3000 = 6,000

3 units = 3 x 3000 = 9,000

5 units = 5 x 3000 = 15,000

Answer:

-62

Step-by-step explanation:

180-w+49(angles  on  a straight line=180)

angles on a triangle=180

Hence,

         180-w+49+w+17+w-4=180

collect the like terms

180+49+17-4+w+w-w=180

242+w=180

Take 180 to the other side and also w

242-180=-w

62=-w    same as w=-62

Answer:

0.430 (nearest thousandth)

Step-by-step explanation:

Using binomial probability relation :

p = 0.81

n = 4

x = 4

1 - p = 1 - 0.81 = 0.19

Recall ;

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 4) = 4C4 * 0.81^4 * 0.19^(4-4)

P(x = 4) = 1 * 0.43046721 * 1

P(x = 4) = 0.43046721

P(x = 4) = 0.430 (nearest thousandth)
