All of these scenarios involve money earned through simple interest. Match each situation with the appropriate
simple interest formula.
For 2 years,
$400 earned interest at a rate of 10%.
X
I = (400)(0.10) (2)
For 4 years,
$100 was saved at a rate of 2%.
X
1 = (200)(0.04) (10)
For 10 years,
*
1 = (100)(0.02)(4)
$200 was invested at 4%.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

i’ll just s take the points thxs

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

1.m=2

2.m=-6

3.m=3

4.m=1/2
