it's Tangent or Toa because the opposite and the adjacent are the two sides

since the x is over the 12 because it's opposite over adjacent, we multiply it by the angle 12° and tangent

Arie has 46$ in his account and is saving 8.50 each week Olga has 14$ in her savings account and is saving 12.50 each week after

victus00 [196]

Answer:

After 8 weeks Arie and Olga will have the same amount in their accounts

Step-by-step explanation:

Assume that Arie and Olga will have the same amount in their accounts after w weeks

∵ Arie has $46 in his account

∵ He is saving $8.50 each week

∵ He will do that for w weeks

- To find his amount after w weeks add 46 to the product of

w and 8.50

∴ Arie's amount = 8.50 w + 46

∵ Olga has $14 in her savings account

∵ She is saving $12.50 each week

∵ She will do that for w weeks

- To find her amount after w weeks add 14 to the product of

w and 12.50

∴ Olga's amount = 12.50 w + 14

∵ They will have the same amount in w weeks

- Equate their amounts

∴ 12.50 w + 14 = 8.50 w + 46

- Subtract 14 from both sides

∴ 12.50 w = 8.50 w + 32

- Subtract 8.50 w from both sides

∴ 4 w = 32

- Divide both sides by 4

∴ w = 8

After 8 weeks Arie and Olga will have the same amount in their accounts

Is it ever too late to save for retirement?

Mekhanik [1.2K]

It can be too late to save for retirement. You want to begin saving at least 45 years before you plan to retire.

<h3>When to start savings for retirement?</h3>

Retirement is when labour stops working at a regular job. When a person retires, they would have a reduced source of income. This is why it is important to save for retirement. The earlier one starts to save for retirement, the more money the person would have when they retire.

The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults. On a certain day

GaryK [48]

Answer:

Number of child tickets = 800

Number of adult tickets = 330

Step-by-step explanation:

Let c = number of child tickets

and a= the number of adult tickets.

We are given:

The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults.

On a certain day, 1,130 enter the festival and 2, 520 is collected.

Making equations:

$c+a=1130$ (because total people entered are 1130, so adding number of adult and child tickets will give us total number of people)

$1.50c+4.00a=2520$ (because total money collected is 2520, so adding coat of adult and child tickets will give us total money)

Now, solving these equations simultaneously, we can find values of x and y

Let:

$c+a=1130--eq(1)\\1.50c+4.00a=2520--eq(2)$

From equation 1 find value of c and put it in eq(2)

$c+a=1130\\c=1130-a$

Putting value of c in eq(2)

$1.50c+4.00a=2520\\Put\:c=1130-a\\1.5(1130-a)+4a=2520\\1695-1.5a+4a=2520\\-1.5a+4a=2520-1695\\2.5a=825\\a=\frac{825}{2.5}\\a=330$

So, we get value of a = 330

Now, punting value of a in eq(1) to get value of c

$c+a=1130\\c+330=1130\\c=1130-330\\c=800$

So, we get value of c = 800

Therefore:

Number of child tickets = c= 800

Number of adult tickets = a = 330
