2.When you open a checking account, what do you need to have with you?

3.What are three tips for writing checks?

4.What could happen if you do not keep track of the checks you write?

5.What is it call when you put money into your account?

Answers

Answer:

1. I believe that the difference between  keeping an account & and a fee for an account is checking accounts don't have much interest, and are better for more purchases in bills and payments. For a fee like saving accounts, it's better for saving the money and such things like that.

2. You must require your two forms of identification. Which is a Social security card, driver's license, a state ID, and a passport or birth certificate at most. This is what you need to have with you when opening a checking account.

3. Use decimal points in order to tell the differences between dollars and cents. Those can easily mix up. Put a accurate date of what time you signed the check. Put out the amount in words, it helps a lot just incase they can't read the numbers.

4. If you could not keep the track of checks you write, it could mean that you have bounced the check. "Bouncing" the check means that you don't have enough money in your account to provide paying for it. Therefore, the bank gives you multiple fees and a organizer of all checks that you could not afford because you were not keeping up with the track of checks you wrote.

5. This is called a cash deposit.

In a right angled triangle, right angle at C, if AB = 32 cms and sin B=5 by 8 find AC ​

Answers

The numerical length of side AC is 20 units

How to determine the length of AC?

The given parameters are:

AB = 32 cm

sin(B) = 5/8

The possible triangle is added as an attachment

From the attached triangle, we have the following sine ratio

sin(B) = AC/AB

This gives

5/8 = AC/32

Multiply both sides of the triangle by 32.

So, we have

AC = 32* 5/8

Evaluate the product

AC = 20

Hence, the numerical length of side AC is 20 units

pamala has 84 and alannah had 12$ how money must pamala give to so that alanny will three times as much as pamala

Answers

In order to make the Alannah's money 3 times the Pamala's money, Pamala need to give Alannah $ 60.

Money with Pamala = $ 84

Money with Alannah = $ 12

Now let the money given by Pamala to Alannah be x

So, for money with  Alannah to become 3 times of the money with Pamala, we get the equation as:

3 ( 84 - x) = ( 12 + x )

252 - 3 x = 12 + x

3 x + x = 252 - 12

4 x = 240

x = 240 / 4

x = $ 60

Pamala gave Alannah $ 60.

Therefore, we get that, in order to make the Alannah's money 3 times the Pamala's money, Pamala need to give Alannah $ 60.

Fadil sells televisions. He earns a fixed amount for each television and an additional $20 if the buyer gets an extended warranty. If Fadil sells 11 televisions with extended​ warranties, he earns $770. How much is the fixed amount Fadil earns for each​ television

Answers

Answer:

770.00 divided by 11 = total cost of 70.00 per tv, subtract 20.00 for extended warranty, TVs were 50.00 each.

Answer:

$50

Step-by-step explanation:

Given: The amount earned by Fadil on selling 11 televisions= $770

Therfore, the amount he earned on selling 1 television=

[tex] \frac{770}{11} [/tex]

=$70

Since, he sold televisions with extended warranty and he earns $20

Then, the fixed amount Fadil earns for each television= $70-$20=$50

So, Fadil earns $50 as the fixed amount for each television.

Dividing the given polynomial by (x+1) yields a quotient of x^2 +10x +21. That factors as (x+3)(x+7), so the three zeros are ...

  x ∈ {-1, -3, -7}

The factors of x^2 +10x +21 are found by looking for factors of 21 that have a sum of 10. Those factors are 3 and 7, so the complete factorization of f(x) is ...
