Answer:

i got you bro

Step-by-step explanation:

It is very easy to estimate 10% of any number - just divide by 10 by moving the decimal point one place to the left.

Once you know 10% of an amount, it is possible to find 5% by dividing the value that is 10% by 2. Adding these answers gives a quick estimate of 15%

For example: "Find 15% of 300"

10% of 300 = 30 and 30÷2=15

15% of 300 = 30+15 =45

In the same way for this question ...

Treat 89.50 as $90 Find 10%, then 5%.

#10% +5% = 9+13.50#

15% of the bill is about $13.50

Margaret deposits $1,000 in a savings account that pays 1.4% interest compounded
ozzi

Answer:

The balance after 1 year is;

$1,014.05

Step-by-step explanation:

To do this, we use the compound interest formula

That will be ;

A =P (1 + r/n)^nt

A is the amount generated which we want to calculate

r is the rate = 1.4% = 0.014

P is the amount deposited = $1,000

n is the number of times it is compounded annually which is 2 (semi-annually means 2 times in a year)

this the number of years which is 1

we have this as:

A = 1,000( 1 + 0.014/2)^(2*1)

A = 1,000(1 + 0.007)^2

A = 1,000(1.007)^2

A = $1,014.05

I rlly need help :( this is hard
GrogVix [38]

Answer:

A

Step-by-step explanation:

The domain does not exist when the denominater of an equation is zero. So in this case if x was -2 and we added 2 the denominator would be zero, and that value does not exist in the domain. Hope this helps!
