Y and x have a proportional relationship, and y = 25 when x = 60.

Answer:

This equation can be solved by using y = kx.  

Since y = 25 when x = 60,

25 = 60k and if we solve for k then k= 5/12.

That means the equation we're using is

y = (5/12)x.

Plug in y = 30 and you get

30 = (5/12)x

Solve for x

30 * (12/5) = x

360/5 = x

x = 72

You invest $1600 in an account paying 5% interest compounded daily. What is the account's effective annual yield? Assume 360 day
Pavlova-9 [17]

Answer:

5.13%.

Step-by-step explanation:

Amount  accumulated in 1 year

= 1600(1 + 0.05/360)^360

= $1682.03

Account's effective annual yield

= 82.03 * 100  / 1600 %

= 5.13%.

-6a-4= -4 (1+7a) Solve for a.
soldi70 [24.7K]

Answer:

a = 0

Step-by-step explanation:

On the right side of the = multiply -4 through

- 6a - 4 =  - 4 - 28a

add 28a and add 4 to both sides

28a - 6a = 4 - 4

22a = 0

divide both sides by 22

a = 0

Help.. or die.. you decide.

Answer:

<u>Problem 1:</u>

x = 12 unit ; y = 120 ; z = 60 ; perimeter = 58 unit

<u>Problem 2:</u>

FG = 16 unit ; EG = 2√153 unit ; y = 5 unit

Step-by-step explanation:

<u>Problem 1</u>

Since ABCD is a parallelogram. so,

∠ABC = ∠ADC  [Since opposite angles of a parallelogram are equal]

but, ∠ADC = 120° [given]------------(1)

So, ∠ ABC = y° = 120° ----------------(2)

Again, sum of two consecutive angles of a parallelogram is, 180°, so,

∠BCD + ∠ADC = 180°

So, ∠BCD =z°  =  180° - 120° = 60° [Putting the value of ∠ADC from (1)]-----(3)

Again, since opposite sides of a parallelogram are equal,

so, BC = AD

⇒ (x + 5) = 17

⇒ x = 12------------------------(4)

So, AB = 12 unit , AD = 17 unit

So, the perimeter of the parallelogram is given by,

2(AB + AD)

= 2 \times (12 + 17)  unit

= 58 unit --------------------------------------------------------------(5)

<u>Problem 2</u>

Perimeter of parallelogram EFGH = 52 unit

So, 2(EH + GH) = 52 unit

⇒ 2 ( x + x + 6) = 52

⇒ 4x = 40

⇒ x = 10

Now,  FG = EH [since opposite sides of a parallelogram are equal]

            = (x + 6) unit

            = (10 + 6) unit = 16 unit ------------------------------(1)

Again for a parallelogram, the diagonals bisect each other.

so, EG = 2 \times \sqrt{153}

           = 2√153 unit -----------------------------------------(2)

and,

3y - 10 = y

⇒ y = 5 -----------------------------------------------(3)
